Bionicle Legends is the third book series based in the Bionicle universe. It is currently ongoing, and covers the events that are occurring in the storyline's 2006-2008 story arc. It follows the Bionicle Adventures series; but as Adventures is almost exclusively told in flashbacks, the events preceding those in Legends are told in the first book series, Bionicle Chronicles.
In Bionicle Legends, the Great Spirit Mata Nui is dying, and the universe will die with him if nothing is done. A new group of Toa must find the Mask of Life that can save him before it is too late, but other more sinister groups also want such a powerful mask.
The 2006 arc of Legends was adapted into the Bionicle Heroes video game, but the game is non-canon and has many inconsistencies with the actual storyline.
The following sources provide background information and tell side stories taking place during Bionicle Legends:
The Toa Inika, six Matoran that journeyed from Metru Nui, are created when they are struck by mysterious Red Star energy. With the aid of the Voya Nui Resistance Team, a group of Matoran, they rescue the Toa Nuva.
The reconstruction of Metru Nui is underway as the Turaga call a meeting with the Toa Nuva and Toa Takanuva. Turaga Dume and Nuju reveal their discovery. By studying the stars, they have found the Great Spirit has fallen from his coma-like state and is dying. After his death, the universe will die along with it in three days. His only chance of survival is if the Toa Nuva recover the legendary Kanohi Ignika, the Mask of Life, to save him. Dume leads the Toa Nuva underground to Toa Canisters and send them on their journey, to the island of "Daggers of Death". Toa Takanuva stays behind to guard the metropolis as per his destiny.
On Voya Nui, the Piraka, Zaktan, Avak, Thok, Reidak, Vezok, and Hakann, arrive and masquerade as Toa (see BIONICLE Legends 4: Legacy of Evil). Despite their claims, it is their frightening appearance and demeanor which primarily makes the Matoran natives fall into the Piraka's plot. Thus, the Matoran survivalists are convinced, and begin the construction of the Piraka's fortress, the Stronghold, as well as temples and statues in their honor. They are also used to dig trenches for "lava-farming" out of Mount Valmai to search for the Ignika. This makes six Matoran suspicious of their claims, and form the "Voya Nui Resistance Team". They watch the Piraka closely and take place in the theft of a mysterious artifact they created, a Zamor Launcher, ultimately believing they will use the weapon against them.
After skirmishes with the Piraka, including Dalu's attempt to increase Avak's senses, Hakann and Avak create a monster of rock and lava to fool the Matoran, and defeat the monster, hopefully to better the Piraka's image. Using Antidermis, Zaktan creates a Zamor Sphere to test upon a Ta-Matoran subject named Dezalk, which makes the Matoran obedient and loyal, sending him to assemble the Matoran where the Piraka enslave the Voya Nui Matoran save the resistance team. Meanwhile, the Toa Nuva arrive, and despite the Resistance Team's intervention, and defeated by the Piraka. Zaktan commands their tools and Kanohi are to be stripped, and the Toa Nuva to burn in Mt. Valmai. During this time, Balta, in an attempt to steal a Zamor Sphere, traps himself in a cave.
Back on Metru Nui, Jaller organizes a labor strike until the Turaga divulge the Toa Nuva's sudden disappearance, believing the Matoran have been protected too closely for far too long. Turaga Nokama meets with Jaller secretly to discuss the events, and Jaller organizes a team with Matoran from each Metru, Hahli, Hewkii, Nuparu, Kongu, and Matoro, and they depart to aid the Toa Nuva.
On Metru Nui, Turaga Dume holds a conference with the Turaga. He reviews the events of the previous meeting and confesses his doubts on the Toa Nuva, who have not returned with the Ignika. More importantly, he accuses the Turaga of revealing this, as Takanuva and Jaller's team departed the night before, vanishing into the Underwater Chutes of Le-Metru. Nokama confesses, and the Turaga are forced to wait as Takanuva is not available to dispatch. At the same time, Takanuva and Jaller's team emerges from a Chute onto a land bridge.
Takanuva attempts to unsuccessfully persuade Jaller to return to Metru Nui and let him continue the mission, and scouts ahead up a tunnel. When he uses his Light powers to illuminate the tunnel, he finds his Light powers are disabled in the tunnel, and becomes disoriented and confused. After a while, the Matoran team decide to enter the tunnel, their Lightstones fail, and they link themselves with cable and continue to talk to ensure they would not become separated.
Matoro is worried as Nuju said the way to Voya Nui was through a "land of the dead", but is ignored. He then no longer hears his allies' voices even when he shouts, and stumbles in the darkness. He feels a hand grab out to him and helps the figure to his feet, and continues to follow the cable, where the Matoran and Takanuva await. The figure is no longer in the tunnel, and is revealed to be an extension of the Kanohi Ignika. They continue down a long strip of land, with a stone archway far away.
Jaller offers if anyone wants to turn away do so now, but no one declines. Hahli wonders about Takanuva and Teridax, and if Teridax's defeat was intentional, and Hewkii finds a Kanohi Suletu, Takanuva acknowledging its existence by wearing the Kanohi and listening on Hahli's thoughts. The team sets down close to the Archway, Jaller standing guard as the Matoran slept. Jaller questions Matoro's attitude after they escaped the tunnel, but they are interrupted by Takanuva sighting a Matoran in the archway, which awakens the others. They continue toward the Archway, Takanuva explaining that the Matoran disappeared before contact was made, and he attempts to pass through the Archway only to be repelled, along with the power of light.
The Matoran pass through the Archway, but are unable to get back. Hahli warns them from a tablet she found, describing that "This is a realm of shadow ... of famine and plague and blight ... This is a world of darkness ... and there is no place for light." Sadly, Takanuva is forced to depart for Metru Nui again and the Matoran continue onward, with a message to update the Turaga and not send any assistance. The team continues up a mountain, and are met by eight Manas. They are led into a canyon of Matoran in various states of disrepair. The land is desolate, waterfalls of dust, volcanoes of hot ice, thunderless lighting and thunder-producing water. The ground screams as they walk past stone statues of Matoran and the un-repaired Matoran follow them. They are led to a armored being, with a horrific patch-work mask and chains of fire. His name is Karzahni, the ruler of this land named in his honor.
Hahli remembers this place from the Turaga's tales, where "lazy" Matoran were sent. Karzahni describes a hundred thousand years ago, Matoran of laziness and disrepair were sent here, and when the team mentions Mata Nui would not accept such a place, he is confused. The Matoran then confiscate the Matoran's supplies and tools (to strip their identity), and when asked for their masks, Jaller refuses, learning of his Kanohi Hau belonging to Toa Lhikan. He is forced to carry out his wishes when Karzahni gives him a vision of an alternate future where Takua dies.
The Matoran are re-purposed, Hahli works with Karzahni. As the Chronicler, she educates him in the events of the past hundred centuries. The other Matoran are put to work in the furnaces, where they meet an Av-Matoran who resided there before the light-barrier Archway was constructed. His mind insane, he rambles about his previous identity, working in a "world that feeds the world" where he constructed the Toa Canisters. He reveals a set where hidden in Karzahni, and despite his warnings that Matoran would not survive the journey, they journey underground to them. Karzahni tries to stop them, but when he gives a vision of the death of the Great Spirit and its effects, he hesitates, and Jaller's team escape for Voya Nui.
On the "Island of Doom", the Piraka carry the unconscious Toa Nuva to Mt. Valmai, but an eruption stops them from doing so, and they flee. The Toa Nuva regain consciousness in time to save themselves. After recovering, the run into the Voya Nui Resistance Team, but the group believes them as threats as well, and they attack the Toa Nuva, who refuse to retliate against that which they chose to protect. Gali Nuva is driven insane when Dalu enhances her sight, and flees from the area, coming into the custody of Axonn, who heals her and frees Balta from the cave. The two return to the conflict and the Toa Nuva and Matoran ally, and they journey for the Piraka's Stronghold to find the Nuva's Kanohi and tools.
Meanwhile, Zaktan is furious upon the Toa Nuva's survival. He reveals the Piraka's seventh member, Vezon, briefly, and sends Thok to work the Matoran harder, as the volcano had slowed after the eruption. Zaktan later meets with Brutaka, and Hakann overhears. He fires a Zamor Sphere at the titan, which only appears to make him stronger. He follows the gold and blue armored warrior, and strikes a deal that if he can control the Zamor Spheres, he can grant them to Brutaka, they too journey to the Stronghold. Coincidentally, Avak and Thok, searching for the Toa by the green belt of Voya Nui, realize the Ignika must be hidden there, and conclude Zaktan was using Mount Valmai as a diversion. They retreat to the Piraka Stronghold to confront him.
A battle begins within the Stronghold between the Piraka. Reidak attempts to enter the Stronghold and encounters the Toa Nuva, aiding them in getting inside. The Toa Nuva recover their tools and masks. Zaktan once again resumes control of Brutaka, offering the secret of Antidermis. Brutaka defeats the Toa Nuva and the Matoran, and he takes the Toa into his custody. The Piraka continue to hold onto a loose alliance, and interrogate the Matoran.
(Events from Comic 1: If a Universe Ends are in italics.)
Dalu is able to regain consciousness as the Matoran are taken to the Chamber of Truth. She escapes, but runs into Hakann and Zaktan. Hakann blames Zaktan for her escape, as he was too busy boasting his victory over the Toa Nuva. They fight, and Hakann barely survives, crushed under a mountain of rubble. Dalu escapes again.
Meanwhile, on Mt. Valmai, Thok and Reidak discuss the Ignika. Reidak complains about not having anyone to "break in half", and Thok pushes him off the mountain. Reidak climbs back up and hits his Piraka "ally" with his Buzzsaw.
Meanwhile, the Matoran arrive on the shores of Voya Nui, and the Red Star shoots a bolt of energy which splits into six lighting bolts at the Canisters. When the Matoran emerge, they are no longer Matoran, but six Toa Inika.
From afar, Axonn watches the defeat of the Toa Nuva and the Voya Nui Resistance Team. He reflects upon how they ended up there. Axonn and Brutaka are part of a organization named the Order of Mata Nui, devoted to the Great Spirit. They were assigned to protect the Kanohi Ignika on Voya Nui, unfortunately, Brutaka lost faith within their mission, as Voya Nui separated itself from the Southern Continent and the Great Cataclysm. Soon, Brutaka betrayed his mission to ally himself with the Piraka to ultimately steal the Kanohi Ignika.
Brutaka, as well ponders his history, while aiding the Piraka in interrogating the Voya Nui Resistance Team, and when Dalu attempts an escape, he saves her from a Doom Viper. He leaves, troubled by his choices. After the incident, Garan is questioned, and the Piraka are troubled by the sight of six Spirit Stars, specifically the Toa Inika's. Vezok attempts to throw him in a crevice of lava, but he is rescued by the Voya Nui Resistance Team.
Meanwhile, the Toa Inika start to figure out their next move; noting especially odd things about their transformation like glowing faces and living masks. They end up triggering their mask powers, causing chaos as Nuparu flies uncontrollably, Kongu can't keep from hearing others' thoughts, Matoro's spirit is separated from his body, and Hahli seems to be talking to thin air. As they regain control, Matoro reports that he saw the Matoran, and the Toa agree that they need to meet them and figure out what's going on on this island.
After a scuffle with Vezok, the Toa meet the Matoran rebels and compare notes on what they know. Armed with Zamor Launchers built by Velika, they split up into three groups: Jaller and Hahli go to free enslaved Matoran, Hewkii and Matoro go visit Axonn, and Kongu and Nuparu sneak into the Piraka stronghold to search for the Toa Nuva. While Jaller and Hahli's mission has no problems; Hewkii and Matoro find Axonn badly injured by Brutaka, telling them to stop his former partner even if it means killing him. Worse, Kongu and Nuparu are discovered and faced with all six Piraka and Brutaka.
Thankfully, the other Toa arrive just as the battle starts and Hewkii is able to bury Brutaka under a pile of rock, taking him out of the fight temporarily. While the Matoran search the stronghold for the Toa Nuva, the Toa Inika begin taking the Piraka out one by one. But the tides turn when Brutaka begins to dig himself out: Hakann enacts the plan to steal Brutaka's power for himself, Avak, Reidak, and Thok -- but he intended to take it all for himself, and only quick action by Thok allowed him to take a share of Brutaka's power as well. The two quickly use their new strength to turn on the others, with Hakann knocking them all out with one superpowered mental blast.
When everyone comes to, they realize that Hakann and Thok had forced the weakened Brutaka to reveal the location of the Mask of Life. Axonn arrives and begins to go after the two Piraka, but Jaller tells him to swallow his pride and let others help, to which Axonn agrees. Realizing that the best way to stop the two is to return Brutaka's power to him and that the Piraka are the only ones who know how to do that, the two groups form an uneasy alliance. While the Piraka work on the Zamor Sphere that will depower Hakann and Thok, Axonn warns Jaller of the mask's guardians and hands him a glowing Zamor for "protection". At the same time, the Matoran are continuing their search, and they find records of Voya Nui's history - it was long thought that many were lost when some of the land sank underwater, but these records say that they may still be alive underwater as a prelude to the Mahri Nui story!
Meanwhile, Hakann and Thok have begun to turn on each other. The resulting destruction makes them easy to track, and the Toa Inika and other Piraka quickly arrive on the scene (Axonn chose to stay behind). Though most of the Piraka are taken out of the fight early, Hakann and Thok are soon put at a disadvantage by the Inika. The two call a truce and launch a combined attack, but at the same moment Hewkii hits them with the specially-prepared Zamor. As a result, both sides fall unconscious from their enemies' assault; leaving only Zaktan standing. By the time the Toa Inika awaken, the Piraka are already up and gone, headed down a staircase that leads to the Mask of Life. Agreeing that they can't wait for reinforcements, they quickly follow.
7,000 years prior to the events of BIONICLE Legends:
Vezok and Hakann, two Skakdi, raid a Toa fortress in search of an artifact. As Hakann creates a fracas to distract the Toa, Vezok finds the artifact, a tablet named the Makoki Stone, with barely-discernible writing detailing the Brotherhood of Makuta, in the event that they would rebel. They depart the Fortress and are captured by the Dark Hunter "Ancient", who confiscates the artifact and recruits the Dark Hunters along with four Skakdi, Zaktan, Avak, Thok, and Reidak.
5,000 years prior to the events of BIONICLE Legends:
Zaktan leads his Skakdi peers (minus Avak) in an unsuccessful maneuver to overthrow the Shadowed One, but are confused by the transforming walls of the fortress. The Shadowed One attempts to execute Zaktan for his treacherous leadership of the plot, but his disintegration vision instead transforms Zaktan into a mass of sentient protodites.
4,000 years prior to the events of BIONICLE Legends:
In a blackmail scheme, the Shadowed One sends Reidak, Vezok, and Avak to free the Kanohi Dragon from imprisonment in the seas around Metru Nui, leaving the Rahi to rampage upon the city. When the trio meet with Turaga Dume to offer protection in the event the Dark Hunters' are allowed to establish a base, he declines. Therefore, Vezok attempts an assassination, but is unsuccessful due to the arrival of Toa Lhikan and his Toa Mangai team. The Toa eventually defeat the beast and deport it to Xia, where Roodaka awaits its' arrival.
3,000 years prior to the events of BIONICLE Legends:
The Toa/Dark Hunter War, beginning as a result of Dume refusing to establish Dark Hunter bases within Metru Nui, is well underway. Hakann oversees Nidhiki's betrayal and Lhikan overhearing the matter. He bargains with the Toa of Fire, Nidhiki for the Makoki Stone which Lhikan guarded long ago. He agrees, but six months later, the Dark Hunters have it within their possession again, split into six, and auctioned to the Brotherhood at a profitable price. Roodaka then mutates Nidhiki into an insectoid being, dooming him to a lifetime with the Hunters.
250 Years prior to the events of BIONICLE Legends:
Zaktan, Thok, and Reidak guard Odina against the Brotherhood during the Dark Hunter/Brotherhood War. As the Hunters' are occupied with an unsuccessful Brotherhood attack of Rahkski, Exo-Toa, and Visorak, Zaktan learns from Roodaka the base was initially in the possession of the Brotherhood. Zaktan investigates the matter and uses his protodite abilities to find a entire record of the Brotherhood and their Plan. Zaktan vows to use this knowledge to his nefarious ends. Later, Zaktan recruits his five fellow Skakdi and rebel against the Hunters'. Rogue, they investigate Teridax's lair after his supposed death, which happens just as the Matoran arrive in Metru Nui.
Hakann discovers the Spear of Fusion, and uses it on Vezok, dividing him into two beings, Vezok and Vezon (the latter taking his name as Vezon means "double" in Matoran). They encounter Teridax's essence as "Antidermis", subconsciously informing them to go to Voya Nui for the Kanohi Ignika, and escape the lair as his Mana Ko come after them. They flee to the island of Mata Nui and find the Toa Mata's Toa Canisters, bringing them to the beach. Avak and Zaktan chart a course to Voya Nui and Zaktan informs the Piraka to masquerade as Toa on their arrival. Hakann uses his heat vision to create a small puncture in Vezok's canister as they depart.
The Piraka continue down the hall of 777 stairs to the Kanohi Ignika, and surmise that Vezon awaits them as they found another Toa Canister upon Voya Nui on their arrival. Zaktan lets Hakann lead the way, as he is plagued by the laughter of Teridax within his mind. Meanwhile, Avak discovers Hakann cowering in a corner, his armor gleaming with intense heat.
Meanwhile, the Toa Inika have their own tests to worry about. They soon come across a group of enemies that they had fought in their former Matoran lives, including a Rahkshi Turahk that had once killed Jaller during his search for the Toa of Light. Jaller is able to overcome this disturbing memory, but like all the other Inika, his powers go out of control and end up killing his opponent. Adding to their shame and grief at being killers, the bodies change to look like their old friends, the Toa Nuva. While worried that such things could happen again, they decide that the stakes are too high to abandon their quest. However, before the Toa Inika go on they turn to take one last look at the slain Toa Nuva, only to see that the bodies had disappeared. They then realise that the dead Toa Nuva, as well their earlier foes, were merely illusions.
In their next test, the Toa Inika are trapped and told they must sacrifice one of their own to continue. With his last death still on his mind, Jaller is distracted long enough for Matoro to volunteer himself, on the grounds that he as a translator has less to offer their mission than the others and becomes another foreshadow to the Barrakki story. This sacrifice is accepted and Matoro is disintegrated - only to be re-formed moments later, as the willingness to die for the cause was what was important, not the death itself.
After this, the Toa Inika face Umbra, a guardian of the mask who uses super-speed to attack. Matoro is once again key to passing the test, as he uses his ice power to make Umbra slip and crash. As Umbra turns into a beam of light and becomes even faster, he eventually hits the ice and rebounds around the frozen cave until he is knocked out, making it easy to obtain the mask.
As both groups converge on the Mask of Life, the Piraka are a little bit ahead and they set an ambush, with the Toa Inika ending up trapped and delayed. The Piraka enter the mask's chamber to find that Vezon had arrived far ahead of all of them, and has since been fused to a Fenrakk spider and to the Mask of Life itself. As the Piraka prepare to take the mask by any means necessary, Vezon uses his spear to fuse Vezok and Reidak together, ordering the resulting beast to crush the others. By the time the Inika arrive, Vezok and Reidak are back to normal and all six are knocked out.
While all this is happening, Brutaka wakes up in the Piraka's stronghold under Axonn's watch. While Axonn extends an offer of friendship to his old partner, Brutaka rejects it and attacks. In the course of the battle, he tries to get an edge by summoning a dimensional gate to warp Axonn away. Eventually, Axonn accepts that Brutaka will never be redeemed, and he becomes unstoppable in his anger. Brutaka tries to get to the Piraka's antidermis, which could enhance his strength, but Axonn shatters the vat before blasting Brutaka into unconsciousness. Once this is done, Botar arrives to banish Brutaka for his crimes, though Axonn still expresses hope for his redemption. After all leave the stronghold, Krahka and Tahtorak use Brutaka's portal to escape their exile (which began a thousand years ago in Bionicle Adventures).
As the Toa Inika fight Vezon and Fenrakk, the latter's ability to absorb kinetic energy is proving too much for the heroes; even when the Toa figure out how to weaken the two without hitting them, Fenrakk can just tap his leg on the ground to regain his and Vezon's strength. Eventually, the Toa are able to drive Fenrakk towards the chamber's lava, and Vezon surprisingly encourages him to dive in. As Jaller prepares to go after the mask, Vezon reemerges, with his steed evolved into an even more formidable dragon called Kardas. Needing a plan of attack other than direct assault, the Toa guess that the Mask of Life may have life and thoughts of its own, and Kongu attempts to use his Mask of Telepathy to read the mask's mind. He finds that the mask has grown to despise Vezon, and would happily abandon the madman in favor of a new, nobler guardian - Matoro. When Vezon learns of this he becomes enraged, allowing Jaller to use Axonn's Zamor Sphere. The sphere freezes Vezon and Kardas in space and time, allowing the mask to be removed safely.
Unfortunately, the Piraka have recovered by now, and they aren't about to let the mask go without a fight. But the mask has other plans; as Kardas makes Matoro lose his grip on it, it flies away towards the surface. As the Toa Inika are able to get a small head start following it, Vezok is dead set on re-fusing with Vezon; but the other Piraka smash the Spear of Fusion to ensure that Vezok will never be whole again.
Back on the surface, the Mask of Life dives into the sea. Hahli tries to follow it, but the depths become too deep for her to handle. As she loses consciousness, a Mahri Nui Matoran dives from below and helps her up to the surface, though at the cost of his own life. Before passing on, he pleads with the Toa to help a city beneath the sea.
But in the midst of the Toa Inika's mourning the Matoran, they are reunited with all their friends: the Matoran had succeeded in freeing the Toa Nuva, and Axonn is there as well (Botar had just left after talking to the Nuva). While the Inika worry that the Nuva will take over the mission to save the Great Spirit, the Nuva recognize that this mission is the Inika's destiny and give them their full blessing. Axonn also declares his intent to be the Matoran's guardian; openly instead of secretly this time. The Piraka, watching from afar, decide that taking on twelve Toa and Axonn would be suicide; opting to bide their time.
Soon afterward, the Toa depart on their new missions which are revealed on the web: the Toa Nuva go on a mysterious quest that they have not told the Inika about, and the Toa Inika enter a secret passageway (opened by Axonn) leading to the underwater world where the Mask of Life now resides...
By the time Kyrehx brings the mask to the planning meeting, it has already been adjourned. She instead seeks out someone knowledgeable about Kanohi, but is soon caught and attacked by the very seaweed beneath her feet. She is saved from the plants by Dekar, and she is happy to pass the strange mask off to him.
Meanwhile, Defilak has gathered a crew for his home-built submarine: Gar, Idris, and Sarda. As they descend into unknown territory, they are soon attacked and trapped by a school of Takea sharks, who are led by a bigger, shark-like being who is named Pridak. After the submarine is destroyed, Pridak demands the Mask of Power from the crew and throws Sarda to the sharks when they claim ignorance. He explains that he is a Barraki, one of six warlords banished to the Pit millennia ago for their crimes. Sarda is subsequently saved by the arrival of Toa Lesovikk.
The other Barraki, however, have their own plans concerning the mask: Takadox has Carapar kidnap Kyrehx, and from her tale realizes that the mask is the legendary Mask of Life. He also sends Carapar to return Kyrehx and stop Ehlek, who has gathered his venom eel army and launched an all-out assault on Mahri Nui.
In the meantime, Dekar has found that every enemy he fights has become immortal and invincible. Realizing that his and Kyrehx's strange curses come from the mask, he decides that it is too dangerous to exist. When Dekar tries to destroy the mask - as the remaining two Barraki, Kalmah and Mantax close in on him - it defends itself by enlarging a nearby venom eel to giant size.
The eel begins to attack everything in sight. As Defilak, Gar, and Idris use the chance to escape from Pridak and his sharks; Ehlek and Carapar take the opportunity to snoop around Pridak's lair, where they find a newcomer to the Pit - the mutated Brutaka. Takadox tries to hypnotize the eel into submission, but it becomes distracted by sounds in a long cord of stone that reaches to the surface and it knocks Takadox far away. Dekar, now with a healthy respect for the mask, cautiously touches it and is given a vision of its history, along with the revelation that the Pit's waters are eroding it away and damaging it.
By this time, Pridak has gathered the Barraki, with Brutaka in place of the missing Takadox. As they confront Dekar, Brutaka demands he hand over the mask, swearing that an Order of Mata Nui member such as himself would never let the Barraki have it. When Dekar refuses, saying one who should have the mask would have claimed it himself, the Barraki mock Brutaka for his "lies" about an Order and command a giant squid to drag him off. They then step over to Dekar and take the mask from him, causing it to release a blinding light.
At the same time the Barraki deliver the damaged Kanohi Ignika to Nocturn to keep it safe, the Toa Mahri knock the venom eel unconscious, and head for Mahri Nui. However, the Matoran there are frightened and uncertain about the new arrivals, and open fire on the Toa. Toa Mahri Kongu then creates a gust of wind to blow Defilak out of the air bubble, while Toa Mahri Hahli creates a whirlpool, trapping the Matoran. Then Hahli releases him, and states that if she wanted to harm him, she would have done so. Still needing to be convinced, Defilak asks five of the Toa Mahri to rescue Matoro. Arriving at the fields, the other Toa Mahri are captured by the Barraki, and attempt to lull them into a false sense of security by masquerading as Toa sent to the Pit for incarceration. Matoro is captured by the newly reincarnated Hydraxon.
Hydraxon takes Matoro to the Pit, where he his placed under the watch of the guard robot Maxilos. Matoro's predicament worsens when he learns that Maxilos has become the new body of Teridax, the Makuta of Metru Nui. Teridax frees Matoro, forcing him to ally with him without revealing his identity to the other Toa Mahri. The others, taken to prison caves by the Barraki, escape through the use of their new mask powers; Kongu's summons a giant sea creature, which ends up getting into a battle with the revived venom eel. All the Toa Mahri then return to Mahri Nui, where the others are introduced to Maxilos. Honored by Defilak by being offered the group name Toa Mahri, the six and Maxilos set out to divide the Barraki against each other. Luckily, their efforts prove successful, and the Barraki and their armies begin clashing. Afterwards, however, the Toa are shocked to learn that Mantax's army of rays is approaching Mahri Nui with Hahli at its head.
Working as a pair, Teridax/Maxilos and Matoro find themselves confronting Pridak's army of sharks. After an attack by Ehlek disrupts the assault, Teridax reveals that the stone cord connecting Voya Nui and Mahri Nui must be destroyed in order to put the universe in proper order for Mata Nui's reawakening. Unfortunately, Voya Nui's descent to its proper place will kill all the Matoran on both islands, something that Teridax takes great pleasure from. He then leads Matoro to the ruins of the original Pit, planning to show him the remains of Toa Tuyet so he can find out how to design a Nui Stone. However, shortly after Tuyet is reanimated, Karzahni ambushes Matoro and Makuta and the remains of Tuyet are destroyed.
Knowing that a moment cannot be spared, Matoro leaves his fellow Mahri, and quickly swims with Voya Nui to its place of origin. Meanwhile, the furious Barraki arrive, and have an all-out battle against the five remaining Mahri, and plot to send their armies after Matoro. Meanwhile, Hydraxon, seeing all that has happened, discovers a destroyed Maxilos, with the Spirit of Teridax missing (which will rock the foundation of the Toa's lives once they discover where he is). Matoro beats Voya Nui and descends into the Universe Core, nearly being crushed by the landmass above. There, the sentient Ignika speaks, and informs him to don the Mask of Life, which Matoro accepts as his destiny. The entirety of his life, from Matoran to Toa, flashes, and Matoro realizes that this was where he must be in the end. however, he used his last bit of will to save his friends. His body is then transformed into fierce raw energy, and revives the Great Spirit Mata Nui in a massive explosion.
As the battle between the Toa Mahri and the Barraki rages, a sudden change of events occurs; the Mahri are instantly transported back to Metru Nui, able to breathe air, where Turaga Vakama awaits, informing them of Matoro's deed and of his death. But in their hearts, he will never be truly gone, he is now part of the universe, having transcended to a higher state of being.
When he went to help her, he discovered that she was different. She had been hit with a leech-like creature, and mutated into a monstrous form. She had become the first of the Av-Matoran to have her light drained and become a Shadow Matoran.
In the following week, Kirop, the leader of the Av-Matoran, became corrupted, along with many others. Even Radiak, hero of the Av-Matoran, succumbed to the attack of the enemies, who Kirop revealed to be members of the Brotherhood of Makuta before his corruption. All of the Av-Matoran villages fell save one, where the remaining uncorrupted Matoran were sheltering at the time of Mata Nui's death.
Minutes after the tragic event, Tanma noticed a white Toa falling down the waterfall and there was suddenly a gigantic explosion of light, blinding the three attacking Makuta (Antroz, Vamprah, and Chirox) and bringing the Great Spirit back to life. Likely Tanma ordered all the other Matoran to duck and close their eyes.
A few hours later the Av-Matoran waged a battle against the Makuta and the Shadow Matoran in the sky. And as they did so, the Toa Nuva arrived in Karda Nui, teleported there by Artakha from the island with the same name.
As soon as the toa Nuva Arrived, Pohatu rush to engage the Makuta in battle. Wise Onua was the one that noticed that the bat-like Makuta were blind. The Toa helped the Matoran finish the fight and regrouped at the village, where they began to remember that they once lived in Karda Nui. They discovered the use of their new weapons, which they named Midak Skyblasters. (Midak was the name of a strange Onu-Matoran of Metru Nui who liked the light despite being able to see better in the dark, and Toa Nuva Lewa had always wanted a weapon called a "Skyblaster", and none of the other Toa cared to object, thus the name was created.)
Meanwhile in the Makuta's Shadow Leech hive, Mutran and Vican were working on a new experiment, a Rahi that could turn into a liquid when disturbed. Mutran "kept slipping in it" and ordered Vican to get rid of it. He kicked it out of the hive and it fell into the swamp below, only for Vican to notice too late that it had begun to fly.
Vamprah arrived at the hive and forced Mutran to come to the main Makuta lair to create a flying Rahi to take Vican to Destral to summon Icarax. He created a part-Rahi and part-Matoran creature, and sent Vican off to Destral.
Back at the Av-Matoran's village, the Toa Nuva learned of Matoro's death from the Av-Matoran's description of the events leading up to the blinding flash of light. From this they realized that the Mask of Life that Matoro was last seen with was probably in the swamp below. Tahu, Gali, and Onua departed for the swamp and Lewa, Pohatu, and Kopaka stayed to defend the Matoran. Tahu leading one group and Kopaka leading the other.
Later, an Av-Matoran who looked up to the Toa, named Solek, approached Kopaka and gave him part of an object called a Keystone. It was a tablet detailing how to awaken Mata Nui from his endless slumber, but it had been broken into six pieces. According to Solek, the Makuta held two pieces (one held by Kirop), and the locations of the other three were unknown. Kopaka, understanding all that these Matoran have been through, spoke kindly to him and gave him inspiration for the battle to come, using how Takua became a Toa as an example. It was then that Kopaka learned that Solek knew Takua.
The next day, Lewa happened to knock Kirop out of the sky in battle. Kopaka captured him and with Lewa's help, led him to believe the Toa would be launching an attack on the Shadow Leech hive in a few hours. Kirop found a way out and escaped to the Shadow Leech hive, exactly as the Toa had planned. They followed him, along with Tanma, Solek, and another Av-Matoran named Photok.
In the swamp at the bottom of Karda Nui, the Mask of Life pondered whether or not to create some more guardians for it. But recalling the failures of others like Hydraxon and the gigantic Venom Eel, it decided to create a body for itself, so it could have friends like its former guardian, Matoro.
It also created itself a Skyboard. It flew into the skies above and began silently following Kopaka and the others as the trailed Kirop. It (now considering itself a "he") proved itself by saving the Toa from a hostile flying Rahi by speeding up its life, killing it. The Toa did not notice another flying Rahi escape through the Makuta's portal into Karda Nui, with Vican riding it, heading for Destral.
When the Toa arrived in the Shadow Leech hive, they found no leeches, and just Mutran instead. Kopaka and Solek hung back to take on Mutran, while the others headed further into the hive, which seemed to be bigger on the inside than it was in the outside. They reached a dead-end, and when they turned around to see if Toa Ignika was still behind them, they found that in his place was a gigantic monster. Without worrying about whether it was hostile or not, Tanma (and the others soon afterwards) jumped into battle.
They did not realize that this was an illusion put up by Mutran, and that this monster was actually Toa Ignika. Confused and enraged as to why the Toa were attacking him, he decided to use his Life powers to kill the Toa and their Matoran friends. But eventually the illusion faded and the Toa were able to disrupt Toa Ignika's attack.
Meanwhile, Mutran had attempted to tear Kopaka's mind to pieces, and Kopaka led him to believe he had succeeded, until eventually he turned the tides of the battle and froze Mutran in a blast of ice and snow. It was then that Antroz, Chirox, and Vamprah arrived and quickly defeated Kopaka and captured the heroes. The Toa were chained to a wall, and the Matoran were left in another chamber. Antroz warned the Toa that if they made one hostile move, he would send a mental message to Vamprah and Chirox who were with the Matoran to immediately kill them.
Pohatu collapsed the floor below the Makuta and used his Mask of Speed to race to the chamber with the Matoran before Vamprah and Chirox killed them. He returned with the Matoran, and the Makuta not far behind. Pohatu shared his mask power with the others and the heroes sped around the chamber too fast to be seen and then escaped. Toa Ignika, using his life power, destroyed the organic stone cord holding the hive up and causing it to fall into the swamp.
Vican arrived on Destral before long, and delivered the message to Icarax, who was wearing the mask of Makuta Teridax and sitting in his throne. Though enraged that Antroz was giving him orders, Icarax decided to come, only to tell Antroz he was not to be ordered around.
By the time Icarax had arrived, the final battle had begun. The Makuta laid siege to the Matoran village...only to find that there were no Matoran there. The Toa Nuva and the Matoran were in the Makuta's base, searching for the third keystone.
When the Makuta went after them, a battle occurred. In the end, Mutran used the equivalent of a Nova Blast of Shadow. Icarax had earlier sent Antroz into the swamp, and Toa Ignika had made Icarax into a biomechanical being once more by de-evolving him. And after the Nova Blast, Chirox, Vamprah, and Icarax were nowhere to be found.
The Toa withstood the blast, and Mutran was forced to surrender. The Toa headed into the swamp to meet up with their friends.
But elsewhere, Makuta Teridax's energy floated through an unknown location...a location that would "rock the Toa's universe" to discover. It was a place heavily guarded, but Teridax easily crossed, having no body and being only a cloud of energy. He located his goal, a carving of a Kanohi Hau, and set about his final goal, to accomplish his destiny.
Takanuva wakes up in a room in the Archives where the Onu-Matoran bring dead Rahi bodies for inspection. Illuminating the cave, he notices two Toa standing over him, one Toa of Water, and a Toa of Sonics. The Toa of Water calls herself Helryx, while the Toa of Sonics is Krakua. She explains that they have a message that Takanuva must deliver to the Toa Nuva. Before he leaves, though, Helryx latches her 'pet' Kratana onto Takanuva's Kanohi so he can learn of the past.
Meanwhile, the other three Toa Nuva land in the Swamp of Secrets. They decide to split up, and Onua comes across a giant Nui-Kopen. Slamming it with his fist, it falls into the swamp water, and emerges as a completely different looking creature with tentacles. Before it attacks, Onua's body suddenly does not listen to his will, and he witnesses a yellow Makuta approach him. Bitil explains that his Nynrah Ghost Blaster took over Onua's mechanical parts in his body, then summons duplicates of himself, and they take Onua, who is under their control, to Krika's lair for interrogation. In another part of the swamp, Tahu encounters an enormous spherical structure embedded in a fallen stalactite. He approaches it, but is abruptly blown back by an invisible energy field, and a white Makuta looms over him and prepares to feed.
In Takanuva's visions of the past, he witnesses the Toa Mata being awoken and spoken to by Helryx. After questions are exchanged and hot arguments are quelled, they are led outside of the room they are in, only to be taught more about what Toa are meant to do in their life.
Back in the swamp, Bitil had arrived at Krika's cave. Onua silently realizes that he is no longer under control by Bitil, and quickly gets one duplicate into a headlock. Threatening to tear the Makuta's head off, the other Bitils blast him with energy. Onua rises to see fifty Bitils before him, and he then makes the Earth explode beneath them. His concentration broke, only one Bitil pursues the escaping Onua, who uses his Nynrah Ghost Blaster to create an energy field around Bitil, sending him falling down to the swamp.
In yet another part of the swamp, Gali finds a broken Keystone in the grasp of a sentient plant. After successfully retrieving it, she is attacked by Gorast, who stuns her. After a short, furious fight, Gali traps Gorast in a mud sinkhole. Gorast seemingly commits suicide by drowning herself, but she shortly bursts from the ground and defeats Gali. A huge fireball then illuminates the sky.
Tahu struggles getting up and then rolls away from Krika's grasp. Krika then explains to Tahu why Makuta hate Toa so much, and that is why he must die. Tahu then succumbs to a sudden cold that sweeps over him, and with one final effort, launches an enormous fireball into the sky.
Back in Takanuva's visions, Gali is knocked flat by her trainer, Hydraxon, after being defeated countless times before. She then goes into a short frenzy in a wild effort to defeat him, but fails. She gets up, ready to strike again, but then is knocked down by Spinax. She then finds her way back to the Toa Mata's rest station, and engages in discussion with several of the other Toa.
In the present, right before feeding on Gali's light, Gorast is picked up by Onua and slammed into the ground so hard she almost snaps into pieces. Gali turns out to be alright, and Onua and her escape, Gorast and Bitil wildly on their tails. They eventually arrive at the scene of Tahu's dismay, and a short battle ensues. Chirox, another Makuta, is seen falling out of the sky, and the other three rush to help him, leaving the three Toa Nuva alone. They are guided deeper in the swamp by an Av-Matoran who had appeared to help them escape. They eventually arrive at a small ground surrounded by Lightvines. The Nuva are horrified by what they see in the middle: Matoran-like forms are undergoing strange changes. Suddenly, the forms change into Bohrok, leaving the Toa puzzled. The Av-Matoran explains that the first Bohrok had evolved from Av-Matoran, and the transformations came naturally. Gali takes her eyes off of the robots for a moment, and when she looks back, they are gone. The Matoran guide hands Onua a Keystone, and then lies down and transforms into a Bohrok, and disappears like his other brothers. Tahu then expresses his subtle rage toward the fact that that was the price to be paid for Mata Nui's awakening.
In Takanuva's visions, he sees Lewa underwater, attempting to find his Miru. Frustrated from the attacks of carnivorous schools of fish, he gives up, and Hydraxon laughs at him. Their trainer had taken each of their masks and hidden it somewhere on Daxia. Angered, Lewa comments on how each of the other Toa Mata are doing, then realizes that they can work together. Hydraxon commends him, and Lewa seeks out Gali's help for getting his mask, in exchange for him getting her mask. After the mask search, Tahu and Kopaka scale a mountain to get to an Order of Mata Nui base. They then trick the guards into letting them in, and they are greeted by Helryx, the leader of the Order. She stops working on her project, the Swamp Strider, and then asks them if they will take on the job to become Mata Nui's guardians.
In the present, Tahu and the two other Toa follow a trail created by the Makuta toward Krika's base. They plan a strategy to steal the final Keystone. Once arriving there, they cause timed explosions of their elements to happen. Each explosion goes right, and each Makuta is distracted out of the lair. Seizing the opportunity, the Toa steal the Keystone, and Tahu throws a shield around them from the attack of the non-tricker Krika. Onua digs a huge hole and the Nuva follow it, planning to escape to the Codrex, where they will wait for the other three Toa. Krika and his team follow, planning to ambush the Toa. It turns out the Nuva were the ones planning the ambush. Above the Codrex, they witness the three Makuta and three more Bitils appear, waiting for them. Tahu then lead the two other Nuva in a power dive towards the Makuta in a last attempt to defeat them.
In Takanuva's visions, he witnesses the Toa Mata in Karda Nui, and Kopaka and Tahu fighting off a group of Avohkah. After they are defeated, Tahu and Kopaka debate whether or not they should tell the other Mata the truth about the Codrex and what it is meant for.
Back in the present, a furious battle breaks out against the two teams in the swamp. Eventually, the Toa gain the upper hand, but not before Antroz and his Makuta team come flying down, and prepare to fire at the Nuva. All hope seems lost, when suddenly, an ice blast blocks the blast of energy Antroz fires, backfiring on him. Kopaka, the three Av-Matoran, and the other two Toa soar down, ready to join the fight. Tahu and his team smile as they charge back into the fight, ready for the final battle.
In Takanuva's last vision, Gali defeats the last Avohkah. While Tahu and Kopaka congratulate the team, the final Av-Matoran, Takua, leaves Karda Nui with his friends. While they did that, Tahu and Kopaka led their team to the Codrex. Curious as to what it is, Lewa runs to it, only to be blasted away by the energy field. They insert the Keystone into a niche inside the Codrex's energy field, and enter it. Tahu then closes the entrance, and the Mata witness a huge energy storm brewing inside Karda Nui. Tahu explains what their destinies are, and the other four Toa Mata are outraged by Kopaka and the Toa of Fire for not telling them. Tahu also explains that if they don't get into the six canisters lined up in the Codrex, the storm would kill them all. The team reluctantly enters their canisters, ready for the day that they must awaken.
The Kratana is forcefully ripped off of Takanuva's face, and the Toa of Light then asks how he will go to Karda Nui soon enough. At that moment, Brutaka enters the room, holding the Dark Hunter Dweller in his hands. He then activates his Olmak, and Takanuva steps through the portal, ready to begin his trip to Karda Nui. In the swamp, Makuta Krika carried Gali Nuva off to the west. There, he told her he was giving her a chance to get out of Karda Nui, because if she and her mates succeeded, their future would be the most terrible they could imagine. Before Gali could respond, however, Takanuva, who had just arrived to Karda Nui through a dimensional gate, fired a bolt of light which forced Krika to retreat, with an almost resigned look on his face. Gali recognized Takanuva, but the Toa of Light told her he would explain later his changed appearance. He then showed her a small sundial he carried, saying that if he shone light upon it, the shadow would lead to the location where Mata Nui should be awakened. The two Toa then spotted Pohatu flying through the air. However, after the Toa of Stone joined the group, some Niazesk spotted and attacked them. Takanuva defeated them with a shadow bolt, but that caused Pohatu to believe Takanuva was the Makuta of Metru Nui. However, Takanuva was able to prove the Toa of Stone his identity by having Gali read his mind using a mental link. Pohatu then explained that the Makuta had turned dozens of Av-Matoran into Shadow Matoran. Takanuva swore he would see these Matoran cured.
The three then arrived to the scene of a battle between the rest of the Toa and the Makuta. Takanuva's powers tipped the balance of the fight, forcing the Makuta to retreat.
Tahu then showed the other six Toa the Keystones. Shortly after that, Toa Ignika arrived and told the Toa, using his new knowledge of spoken languages, that he wasn't simply wearing the Mask of Life, he was the Ignika and apparently on a countdown to destroy the universe. Takanuva then revealed that as soon as the Toa Nuva awakened Mata Nui, an energy storm would ravage Karda Nui. However, Tahu said that they would then have to get in the Codrex, the place where Mata Nui was to be awakened, reawaken him and get out of Karda Nui really fast. The Toa then flew off to the battle. No words could describe the fight. Tahu managed to fit the Keystone into niche in the force field surrounding the Codrex and then, as the Toa passed inside, retrieve the Keystones, to prevent any pursuit. However, Antroz managed to slip behind the Toa. Inside the structure, Onua hit a button which made the floor descend. There, the Toa found six giant Lightstones and six pathways leading off in different directions. Lewa, Pohatu and Kopaka found at the end of theirs three vehicles, the Axalara T9, the Rockoh T3 and the jetrax T6. However, before Kopaka could board the Jetrax, Antrox hijacked the vehicle and discovered it acted like eyes for him. Pohatu, aboard the Rockoh and Lewa aboard the Axalara pursued thorugh a maze of tunnels. Lewa tried shooting the Jetrax down, but without avail. Pohatu pursued the Makuta out of the Codrex and used his power over stone to try and stop him, but Antroz managed to shoot the Rockoh down. Lewa then arrived, declaring that only one of them would survive the fight.
Meanwhile Takanuva and Kopaka got out of the Codrex as well and Takanuva remembered that when the storm was going to hit, all the Matoran inside would be killed. He figured he had to evacuate them from Karda Nui. With the help of Tanma, Photok and Solek he captured Radiak. However, as the Toa of light was trying to figure out a way to accomplish his mission, the five met Vican, who declared he had been freed by a Rahi attack on him. Takanuva decided to believe the Matoran.
This sub-story starts with a Matoran named Sarda thrown out of Pridak's cave and about to be killed by Takea sharks. Just when Sarda thought he would die, he was saved by a being who was revealed to be Lesovikk on his sea sled, the last surviving member of the first Toa team, and also an old friend of Sarda's. Nearby, Karzahni, an evil being, lurked in the shadows. He followed the Toa Inika/Mahri to first Voya Nui and then the Pit as he began his own quest to seize power in the universe. Karzahni attacked Lesovikk and Sarda, saying he will soon rule the universe, and first he must "sharpen his claws" by killing the pair.
Karzahni traps Lesovikk with his chains and is about to kill him when Lesovikk tells Karzahni that they met before when Sarda and his fellow villagers were sent to him, so he tried to save them but failed. Karzahni then says that failure will not be new to Lesovikk, but Sarda intervenes and says that Lesovikk is a hero. Acting as a jolt of energy and triggering the power inside Lesovikk, he breaks the chains and prepares for battle. Soon after, Karzahni gives Sarda a horrible vision, which is about him- and all the Matoran- not surviving the descent of Mahri Nui. He falls down, popping his air bubble, and begins to drown. Karzahni gives Lesovikk a choice, to fight and let Sarda die, or to save Sarda and let him go. Lesovikk saves him with an air bubble, but Sarda has already turned into a water breather. Popping the air bubble, Sarda survives, and has Lesovikk tell him how he wound up here. Lesovikk tells him, and Sarda talks with him about defeating Karzahni. Lesovikk, knowing that if Karzahni was merely defeated he would just go back to his realm and do more damage to the matoran, says that Karzahni needs to be destroyed. Later, Karzahni fights Makuta and Matoro, destroying Toa Tuyets corpse. Knowing he is overwhelmed, he summons his Manas that have one thing in mind... kill the enemies of Karzahni. After a long fight, Maxilos/Makuta beats Karzahni, using his telepathy to literally shred Karzahni's mind, and Matoro and Maxilos/Makuta go off to find Icarax, who has obtained the staff.
However, Toa Lesovikk has recruited Idris, and now he, Idris and Sarda are preparing a fight against Karzahni. Lesovikk prepares to make a trap, when Karzahni gives him a vision of the past... except Lesovikk saves his friends from being killed. Lesovikk enjoys it so much, that he decides to stay in that vision.
Sarda and Idris decide to fight Karzahni on their own, preparing a trap for him. Lesovikk stays with his group until one of his former teammates in the vision, Nikila, mentions the Zyglak. Lesovikk suddenly remembers this was a vision, and breaks free of it. He awakes in the Pit, ready for revenge.
When Lesovikk finds Karzahni, He sees his matoran friends luring the being into their makeshift trap. Lesovikk was about to kill Karzahni until he noticed he would be worse off as he was. Plus, Krakua also told him that if Karzani was captured, someone would come to take him away (Botar).
Some time after Matoro and Pridak's battle-using armies of zombies and Takea, respectively, Matoro is swimming with Makuta Teridax. The Makuta taunts Matoro, saying that they are not very different and that all it will take is one bad incident to make Matoro into a being exactly like him. When Matoro retorts, Teridax leads him down into the original Pit to show him something.
Once Matoro is brought through the old Pit, Teridax shows him the long dead body of Toa Tuyet, and tells him her story. He then tells Matoro he wants her reanimated. Matoro, refusing at first, realizes Teridax will destroy him without a second thought (and also curious as to why Teridax wants her alive) brings her back, and sees microscopic shards of the Nui-Stone embedded in her armor. Teridax then tells Matoro that he requires the Staff of Artahka, which the Toa Nuva are currently retrieving. They swim away and encounter Hahli, who asks what he is doing. Matoro, knowing Teridax would kill them both if he breathed a word to her, answers that everything is as okay as the time when Nuparu (back on Voya Nui) carried her over the chasm, and swims away. Hahli, remembering that Nuparu dropped her, realizes that he was trying to send her a message and is in trouble.
Soon after, Matoro and Teridax are ambushed by Karzahni, who destroys Tuyet's corpse and, after a brief conversation with the Makuta of Metru Nui, summons his Manas. However, Teridax uses his Rahi-control power and pits half of Karzahni's Manas against the other half, effectively destroying the entire army. In retaliation, Karzahni uses his mask power of alternate futures to inflicts a vision on Teridax of how Mata-Nui would punish him upon his reawakening. After Teridax recovers, he uses his telepathic powers to take hold of Karzanhi's mind and, in an act of cold hate, rip it apart.
Later, Teridax obtains the Staff of Artahka from Icarax and prepares to use it on a shard of the Nui-Stone. However, Brutaka, now mutated by the Pit mutagen, interferes and calls Botar to take the staff away. Teridax and Brutaka then begin to fight, while Matoro leaves to meet the other Toa. Brutaka and Teridax battle until Brutaka tells Teridax that Nocturn was stripped of his possession of the Mask of Life by Hydraxon. The Makuta then retreats to claim the mask.
As he swims, Teridax remembers the past when he was jealous of Mata Nui and rallied the Brotherhood to betray him. Matoro then ambushes him and freezes Teridax in a block of ice. While imprisoned, Teridax reflects on the power of the Mask of Life, including the painstaking research he did to discover that the Kanohi Ignika is in fact capable of eliminating all life in the universe in an instant. Teridax then realises that his ice-prison is melting, as a result of Jaller's fire attack on Hydraxon. Teridax flexes the powerful body of Maxilos, and breaks free. The names of the 2008 Makuta are revealed here.
On Voya Nui, Axonn and Botar inform the Toa Nuva that the time was here to prepare the universe for the Great Spirit Mata Nui's awakening, and to do so, they must return to Metru Nui. Within the Great Temple lies hidden information and tasks the Toa Nuva must fulfill, and secrecy was important, for if the Brotherhood discovered them, they would attempt to stop them. They fulfilled the first task to free the Bahrag to allow the Bohrok swarms to cleanse the island of Mata Nui, and attempted to retrieve the Staff of Artakha from the Metru Nui Archives. However, Onua recalls Onewa told him the staff was stolen by the Dark Hunters.
The Toa Nuva make their way to Odina, the Dark Hunter base island, approaching from the north. Kopaka freezes the guard "Minion". Lewa uses his Kanohi Miru Nuva to scout and is attacked by energy webs from "Airwatcher". Tahu uses his Kanohi Hau Nuva to shield the Toa as Kopaka ices his wings and Onua defeats him with a blow using his Kanohi Pakari Nuva. They continued to approach the fortress, using Lewa's ability to create vacuums to silence guards before they could sound an alarm. Pohatu takes out a guard and uses his power to open his way into the stone fortress, but the strange ability of the fortress to shift and change forces the Toa into a prison, and the Shadowed One gives them an offer.
The Shadowed One reveals the Staff was given to Xia in exchange for weapons, and would set them free and told them where the Staff was held if they were to eliminate Roodaka, who was recently discovered to be betraying both the Dark Hunters and the Brotherhood of Makuta. Tahu agrees, and the Toa Nuva journey to Xia, Pohatu leaving a timed blast that would shatter every stone in the Dark Hunter fortress to dust in an hour. Tahu reveals he has other plans, sending Lewa to Metru Nui. On Xia, the Tahtorak and the Kanohi Dragon are engaged in a brawl devastating the island. Tahu sends Onua underground to retrieve the Staff just as Kopaka rescues Roodaka.
Roodaka is taken into the Toa Nuva's custody and brought to the Rahaga, whom Tahu sent Lewa to find. The Rahaga had heard of the events of Xia and arrived to aid the Vortixx, and the Toa Nuva force her to use her Rhotuka into mutating the Rahaga back into Toa Hagah. Suddenly, Onua arrives without the Staff and reveals a Makuta named Icarax stole the staff, saying the Brotherhood "was his" and soon Karzahni will be too. The Toa Nuva depart, leaving Roodaka in the custody of the Toa Hagah. When they arrived, the Toa Nuva find the realm abandoned of Karzahni or his Manas, and Lewa and Onua convince the hundreds of Matoran to depart for Metru Nui. Then Icarax ambushed the Toa Nuva, leaving only Gali conscious in the end.
She decides to use a water Nova Blast to defeat him, destroying Karzahni with a thousand-foot high tsunami, using her Kanohi Kaukau Nuva to save the Toa Nuva from drowning. Icarax has disappeared following the subside of the tidal waves, which causes the Toa to awaken from unconsciousness. Tahu finds the Noble Hau of Turaga Lhikan and keeps it. Despite their losses, they continue the tasks and split up. Tahu and Kopaka subdue a group of volcanic southern islands (Artidax, where Miserix was imprisoned), Gali is sent to the island of Mata Nui, Lewa simply vanishes, and Onua and Pohatu recover an artifact known as the Heart of the Visorak.
Gali travels to Mata Nui, where she sees a wounded Kardas Dragon and remains of Bohrok, alluding to a confrontation. Using her Toa Power, she heals the creature, and performs her task, travel to the Great Telescope (mysteriously intact), and focus it on the Red Star. She records information and decides to use her Kanohi Akaku Nuva to zoom in on the star, discovering that there was beings inside it. Startled, she ran from the telescope, intending to track down the others to inform of her discovery. She almost ran into the materializing Order member Botar, who told her she was "needed" teleported her to a chamber with the other Toa Nuva. Helryx's voice sounds, rewarding the Toa for their actions, as Trinuma, holding the Staff, places it into a chamber.
The chamber and the staff create energies reach across the Matoran Universe repairing all damage save for Karda Nui inflicted by the Great Cataclysm. Helryx tells the Toa that they have one final task- the most important- and dangerous of all. They were taken into a chamber to await their final task, catching up on the Toa Nuva's adventures. It was revealed Lewa heard a mysterious voice that told him to dig up the Sundial deep in Mata Nui and bring it to the Metru Nui Archives, when a Matoran steps into the doorway. He tells them they have a great honor, to set foot on Artakha, where he reveals its ruler may lead them into his fortress, or banish them without a thought. Then they are transported to the beaches of Artakha, with the Matoran wishing them good fortune.
Continued in the conclusion of BIONICLE Legends 8: Downfall.
After the Toa Mahri's return to Metru Nui, Takanuva was guarding on the coast when he was attacked by a Shadow Leech unleashed by Makuta Icarax. Fortunately, Brutaka saves him, but Takanuva is left as a Toa of Twilight, able to fire a blast of shadow from one hand and light from the other. However, Brutaka informs him this is not the only problem, and gives him information that could determine the Toa Nuva's fate. Using Brutaka's Mask of Dimensional Gates, he tries to transport himself to aid the Toa, but the mask was damaged and sends him to an alternate reality, where he quickly discovers a world dominated by the Toa Empire, a corrupted version of Toa. Takanuva is brought under capture, and thrown into a cell, where he finds his alternate self: Takua, who tells him what happened to Metru Nui. Learning that the Toa were corrupted when Tuyet gained the Nui Stone and she and Nidhiki killed Lhikan, he also learns Tuyet suspected the Brotherhood's evil, and destroyed them, and anyone else she didn't agree with, so all the Brotherhood's plans aren't currently in progress. As Takanuva realizes that even the Toa Nuva are Toa Mata, and the Turaga and Toa Mahri are still Matoran, Takanuva and Takua break free, and head mysteriously to the Archives.
Instead of the Archives being a Rahi museum, it is a collection of various trophies of Toa conquests, ranging from the Shadowed One's staff to the Mask of Shadows. The two soon find a separate stasis tube, containing Turaga Dume, who was frozen as a result of speaking up against Tuyet. Takanuva frees him and prepares to find Krahka, only for Empress Tuyet to show up unexpectedly.
Tuyet leads them to an unknown section in the Archives where two shadow beings guard. Tuyet is revealed to be Makuta, wearing a cracked Hau. Takanuva tells them a small bit about his universe, and that he needs Brutaka to go back. Makuta says that he will help if Takanuva intercepts an expedition coming back from the island of Artahka with the Vahi, the Mask of Time, and kill the leader. Takanuva inquires about the name of the leader, and Makuta replies "Jaller".
Because intercepting the shipment at sea is to risky, Takanuva is temporarily given the power of flight from Makuta Krika. He then faces against Toa Kualus and Bomonga, guarding Jaller and Pewku. Takanuva tries to bluff his way into guarding, saying that someone is intending to steal the mask. He makes up a number of beings he'd seen on Mata Nui until he mentions Brutaka. But Bomonga had already slain him. his mask and weapons have been stored in the Coliseum. When Takanuva thinks on the days when Toa were respected like heroes, he prepares to take the mask. only for Toa Lesovikk take it first, as he is an enemy of the Empire. He brings him to his secret hideout in Po-Metru, where they meet Pohatu and a band of Matoran. Takanuva learns that Tuyet found something in the Coliseum to summon the Toa Mata from Artahka, since it is too well guarded. She told them to use extreme force to bring peace, but Pohatu didn't buy and fled. Now they plan to decapitate the Toa Empire leadership by breaking into the Coliseum. Instantly, a battle against the Toa Empire and the Rebel-Dark Hunter-Makuta strike force began to have casualties on both sides. Takanuva soon comes face-to-face with Tuyet for real, holding the Nui Stone in one hand, the Mask of Dimensional Gates in the other. She already guessed that he doesn't belong in her universe. Takanuva and Tuyet then battled against each other, with Takanuva's attacks counteracted by those of Tuyets. As Tuyet prepared to finish him off, the pair noticed from a hole in the Coliseum wall that the Matoran and other races had joined the rebellion as well. Takanuva managed to convince Tuyet to open up a portal using the Olmak and go to another dimension where she could start anew. However, as Tuyet prepared to step into the portal, Takanuva ripped the mask off Tuyet's face and entered the portal himself.
Angered, Tuyet followed by grabbing onto Takanuva's leg. During the brief struggle, the Olmak was lost in the dimensional space. The portal generated by the Olmak closed, cutting Tuyet, whose upper body was in the portal when it closed, in half and instantly killing her. Takanuva turned away from the remains of the Toa of Water and continued his journey to Karda Nui, wondering what will happen to the Toa Empire now that Tuyet is gone, and whether he would ever be able to return and find out.
Sometime after the events of Into the Darkness, a team has been formed to combat the Brotherhood of Makuta. Barraki Takadox, Barraki Carapar, Roodaka, Makuta Spiriah, and Vezon, have been detained by the Order of Mata Nui and are to be led by Brutaka. Though Brutaka does not reveal the Order, he informs to the group of their mission and that their involvement with the Makuta species makes them perfect candidates for the job. However, Vezon says that Brutaka actually wants Vezok instead of him, as he had no dealings with the Makuta that gave the Piraka the idea to steal the Mask of Life. With Brutaka as leader, the rest of the team has two choices: Cooperate, or die.
The group made their way to Stelt, the late Sidorak's homeland. Roodaka is cautious because the word is about that she killed Sidorak and Spiriah fears that the Brotherhood of Makuta is on the look for him. They seek out a ship's captain and offer Roodaka as payment for a ship to the south. Vezon offers to give him "a light tap" on the head to make it seem like he was in a fight. But this was just a deception; Takadox hypnotizes the crew into jumping into the water and the captain is knocked out by Brutaka.
Many days later, Brutaka reveals to his team that their mission is to seek out the previous Brotherhood leader, Miserix, who is imprisoned on an uncharted island. However, they are ambushed en route by Zyglak. Brutaka tries to turn away but the winds don't let him; Spiriah used his weather-control power to stop him. He reveals that the Zyglak are working with him, for they are both outcasts. He demands that they turn to Zakaz so he could wipe out his miserable failure of the Skakdi.
Escorted by the Zyglak, Spiriah forces the group to Zakaz and attack three Dark Hunter vessels stationed there. Then suddenly, the Zyglaks' boats begin to sink. Brutaka then reasserts his authority over Spiriah, stating he had someone tail them from Stelt and his "friends", sent armies of Ehlek's species to combat the Zyglak. He then introduces the seventh member of their team... the female Dark Hunter Lariska. It is later learned that two Order of Mata Nui members, Botar and a nine-foot tall warrior named Trinuma, had been dispatched with an arsenal of weapons for a meeting on an island. But Icarax had seen them and attacked. During the fight, Botar was slain, but Trinuma barely escaped. Then he stored the weapons at the first place he came to before he went to Daxia to tell the tale. The group soon finds the weapons, but a wall of stone rises around them that traps them. Spiriah tries to escape by flying away, but is stopped by a stone spear that appears from one of the walls. The group hears a voice, and Brutaka warns the voice of the power it is up against. Then a tentacle shoots out of a cave, and draws Brutaka in. Brutaka has to struggle to keep his sanity in the presence of something so awful. Finally, it speaks again, "Now tell Tren Krom of your power". The ancient entity that existed before Mata Nui, when the universe was young, demanded to know more about it. Lariska tells the entity that the universe is in danger and they must go. As explained by Spiriah, if the Brotherhood's Plan succeeds, then the Makuta will dominate the universe and would eliminate anyone who opposes their rule, even Tren Krom. But Tren Krom said that no being could kill him. Then suddenly, Carapar tried to attack him, but Tren Krom's third eye appeared and shattered him to dust. He lets the rest leave the forsaken island, condemning then to live in the awful universe that they had created, and knowing that any visions he could insert into their heads would be no match for what the team had already seen.
Resuming course for their original destination, Artidax, they encounter traps that could detect a Makuta, which began putting Spiriah into quick sand. Roodaka thinks quickly by turning the sands into fireflyers. The group then decide to turn Spiriah into a detector. To get him to comply, Brutaka "promises" him control of the Brotherhood. As they enter a volcano, Takadox betrays them by causing an avalanche that traps them. After the team managed to get out, they move on but are then blocked by a swarm of insects. After Spiriah's falied attempt to control the insects, Roodaka mutates them, allowing the team to keep moving.
They soon find Makuta Miserix in the form of a giant dragon, chained to a wall. After Brutaka freed him, the Makuta absorbed Spiriah in for betraying him. After the team fought several Klakk in the cave, and Roodaka's attempt to convince Miserix to be her ally, they jump on Miserix's back. The Makuta then sprout wings, and fly away from the island.
