ThunderCats is an American animated television series that was developed and produced by Rankin/Bass Productions, debuting in 1985, based on the characters created by Tobin "Ted" Wolf. The animation was provided by Pacific Animation Corporation, the working name for a collective of Japanese studios prominently including Topcraft, a group who would later go on to form Studio Ghibli. Season 1 of the show aired in 1985 (65 episodes), followed by a TV movie entitled ThunderCats - HO! in 1986. Seasons 2, 3, and 4 followed a new format of twenty episodes each, starting with a five-part story; these aired from 1987 to 1988, 1988 to 1989, and 1989 to 1990, respectively.
The series was originally distributed by Telepictures Corporation which would later merge with Lorimar Productions, becoming Lorimar-Telepictures. Near the end of 1988, Lorimar-Telepictures was purchased by Warner Bros., whose television syndication arm would eventually assume distribution of the show; Warner Bros. would eventually gain rights to the series from that point on.
On March 17, 1997, ThunderCats was the first series seen on (Warner Bros' corporate sibling) Cartoon Network's new action-animation afternoon block, Toonami. The series would depart and return in various timeslots including Saturday mornings and late night marathons until 2002.
There were also several comic-book series produced: Marvel Comics' version, 1985 to 1988; and two series by Wildstorm, an imprint of DC Comics (another Warner Bros. corporate sibling), beginning in 2003. Items of clothing featuring the ThunderCats logo and DVD boxsets of the original series have enjoyed a resurgence in recent years as nostalgia for the former children's favorite has grown.
It was announced on June 5, 2007, that Warner Brothers is making a CGI-animated feature film of ThunderCats, based on a script written by Paul Sopocy. In October 2007, Variety magazine revealed that Jerry O'Flaherty, veteran video game art director (Gears of War), had signed on to direct. The film is being produced by Spring Creek Productions. It is set for a summer 2010 release.
follows the adventures of the eponymous team of heroes, cat-like humanoid aliens from the planet of Thundera
. The series pilot pays homage to the origin of Superman
, as the dying Thundera meets its end, forcing the ThunderCats (a sort of Thunderian nobility) to flee their homeworld. The fleet is attacked by the Thunderians' enemies, the Mutants of Plun-Darr, who destroy all crafts save for the flagship containing the young Lord of the Thundercats, Lion-O, his protectors, and the mystical Eye of Thundera, the source of the ThunderCats' power, embedded in the hilt of the legendary Sword of Omens. Although the Mutants damage the flagship, they are driven back by the power of the Eye, and Lion-O's elderly guardian, Jaga, pilots the ship to the safety of the world of "Third Earth," but perishes in the process (there were insufficient cryo-stasis pods aboard the ship, and the journey to Third Earth takes several decades even with advanced interstellar spacecraft).
When the ThunderCats awake from their suspended animation on Third Earth, Lion-O discovers that his suspension capsule has failed to inhibit his aging, and he is now a child in the body of a man. Together, the ThunderCats and the friendly natives of Third Earth construct the "Cat's Lair" their new home and headquarters, but before long, the Mutants track them down to Third Earth. The intrusion of these two alien races upon the world does not go unnoticed, however - the demonic, mummified sorcerer, Mumm-Ra, recruits the Mutants to aid him in his campaign to acquire the Eye of Thundera and destroy the ThunderCats so that his evil might continue to hold sway over Third Earth.
This status quo holds strong for the first season of the show, and serves as the basis for a vast array of stories that freely mixed elements of science fiction and fantasy into a traditional good-versus-evil tale that steadily introduced more and more recurring allies and villains into the world of the ThunderCats. Futuristic technology is just as central to the series as magic and myth, but even in the midst of all this action, the series never under-emphasizes the importance of moral values in solving problems. Each episode would normally include a short denouement, featuring the characters recuperating after the events of the story and taking the time to single out a personal value or wholesome approach that helped save the day, or could have done so if they had not overlooked it.
The first half of Season 1 featured a gentle continuity, with early episodes following on from one another and establishing recurring concepts, although this became a little less common as the season transitioned into its second half, which was mostly comprised of incidental one-shot adventures. Tying the second season together was the over-arcing five-part adventure, "Lion-O's Anointment," in which the hero battled the other ThunderCats to truly earn his title as Lord of the ThunderCats. Although intended to be viewed consecutively (as the adventures depicted occurred one day after the other), the five parts of the mini-series were erroneously aired (and released on DVD) with multiple other episodes between each installment.
The 1986 TV movie "ThunderCats - Ho!" featured the first major shake-up to the status quo of the series, introducing three new ThunderCats who had also survived the destruction of Thundera. A massive cast of returning heroes and villains were incorporated into the story to make it the most epic ThunderCats adventure yet produced, and it concluded with the apparent destruction of Mumm-Ra. When the series returned in 1987, however, this was quickly proven not to be the case in the opening mini-series, "Mumm-Ra Lives!", as the evil wizard survived his fate. "Mumm-Ra Lives!" set the pattern for the show's final three seasons, which each began with a five-part mini-series that established the new characters and concepts that would go on to influence the rest of the season. In the case of "Mumm-Ra Lives!", these concepts included the debut of the villainous Lunataks, who became a third faction that existed for the rest of the series, and the new team of ThunderCats from "ThunderCats - Ho!" being given their own headquarters, vehicles and so forth.
The 1988 season began with "ThunderCubs," a miniseries named for its plot about the ThunderCats being transformed into children, but which was principally about Mumm-Ra reconstructing Thundera in order to retrieve the weapon that had destroyed it, the Sword of Plun-Darr, and the legendary Treasure of Thundera. In the course of the adventure, the treasure - containing the Book of Omens, a tome holding all the secrets of the ThunderCats, and many other mystical items - was scattered across the New Thundera, ushering in a new concept for the series: a season with an actual story arc. Continuity between episodes became tighter as the ThunderCats, Mutants, Lunataks and Mumm-Ra alternated their adventures between Third Earth and New Thundera, searching for the treasure and exploiting its powers. The season also featured the running theme of the Ancient Spirits of Evil having to take a more active hand in pushing Mumm-Ra into action, culminating in another unique feature of the season - an actual finale episode, "The Last Day," in which the spirits give Mumm-Ra one last chance to destroy the ThunderCats. Ultimately, the villain failed, and was banished to the farthest corner of the universe by the spirits.
However, the 1989 season proved that you can never keep a good villain down. In the opening miniseries, "Return to Thundera!", the ThunderCats returned to New Thunderato rebuild their society, but before departing, they destroyed Mumm-Ra's pyramid, enraging the Ancient Spirits of Evil to the point that they brought Mumm-Ra back, and installed him within a new pyramid on New Thundera. The season proved to be quite divorced from what had gone before, with adventures consigned almost entirely to the wild and wonderful locales of New Thundera, and most villainous opposition coming from either Mumm-Ra or assorted new villains. The Mutants, Lunataks and Captain Cracker all returned for one episode each, however, and at the conclusion of the series, the mystery of the Book of Omens was at last solved, and the tumultuous and terrifying environment of Thundera was at last rendered peaceful and pristine.
- Lion-O (Larry Kenney) — The leader, and the hereditary "Lord of the ThunderCats." Lion-O, based on the lion, wields the legendary Sword of Omens, able to fire bolts of energy and allow Lion-O to see across great distances with its power of "Sight Beyond Sight," and the Claw Shield, a gauntlet that launches grappling lines from its claws. A mere child of twelve years old at the time of Thundera's destruction, Lion-O aged to adulthood during the trip to Third Earth when his suspension capsule failed to prevent his aging. Although cunning and skillfull, he is truly a child in a man's body, and throughout the series, must learn what it takes to become a true leader and gain true maturity. In the latter half of the show's first season, Lion-O has to put all that he has learned to use in the "Anointment Trials"contests of strength, speed, cunning and intelligence against each of the other ThunderCats. Ultimately triumphing over Mumm-Ra in a final battle in the heart of the villain's pyramid, Lion-O is crowned the true Lord of the ThunderCats in an august ceremony attended by nearly every inhabitant of Third Earth. Lion-O also has the ability as Lord of the ThunderCats to command all cats, as he demonstrated in his battle with the Snowman of Hook Mountain when he commanded Snowmeow to halt.
- Jaga (Earl Hammond) — Known as “Jaga the Wise”, based on the jaguar, this elder warrior was once regarded as the greatest of all ThunderCats. An adviser and protector of the Lord’s family, it was Jaga who gathered the nobles of the ThunderCats to escort Lion-O and the Eye of Thundera to safety, but in his aged condition, he did not survive the trip to Third Earth. However, Jaga does reappear on Third Earth as a spirit — seen only by Lion-O at first, to guide him in his lessons and adventures. At times, he appears before the other ThunderCats as well, such as when facing down Grune the Destroyer, and when the ThunderCats need to rescue their fellow Thunderans. When he was alive, Jaga also wielded the Sword of Omens and was a formidable fighter in combat.
- Tygra (Peter Newman) — A staunch, level-headed warrior, based on the tiger, Tygra is known as the ThunderCat architect and scientist. He is the one Lion-O often turns to as second-in-command and for counsel. He is responsible for the design of all of the ThunderCat structures on Third Earth — Cat’s Lair and the Tower of Omens. He is also gifted with ‘mind-power’ — the ability to create life-like illusions in other people’s minds; he used this for Lion-O’s Anointment Trial, but it puts a great strain on him. He uses a whip-like bolas in combat, with which he can render himself invisible to the naked eye. In the episode "All that Glitters", Lion-O instructs Tygra, "If I do not return, you will be the new Lord of the ThunderCats" verifying that indeed, Tygra is the second-in-command. Where creators described Panthro's character as being based on "strength" and Cheetara's character as being based on "speed", Tygra's character was described as being based on "integrity."
- Panthro (Earle Hyman) — The next noble and also the eldest (after Jaga), based on the panther, this warrior is the chief mechanic/engineer and pilot for the ThunderCats. He’s also physically the strongest and is a cunning warrior in combat. With Tygra’s help, he builds all of the vehicles the ThunderCats use on Third Earth — including the ThunderTank, the Feliner and the ThunderClaw, ThunderStrike and HoverCat. A jovial soul, he’s also quick to lose his temper and has a paralyzing fear of bats and a dislike of spiders. In combat he uses a pair of chained fighting sticks (nunchaku) which house several chemical spray-compounds that he can use against foes. The spikes on his chest bands can be used like projectile weapons or as rappelling lines.
- Cheetara (Lynne Lipton) — A female warrior, based on the cheetah, who is the only adult female ThunderCat (until the later appearance of Pumyra). She is as lovely as she is brave and caring. Often a voice of reason, she is also the bearer of a budding ‘sixth sense’, detecting when something is unsafe or if evil is near. This precognitive sense, which Cheetara regards as a curse for the most part, also allows her to perceive visions — whether involuntary or by forcing herself — but this drains her and she may require days or weeks to recover. She has incredible speed, once clocked at speeds of 120mph on a morning jog. She can only maintain this top speed for a short moment, but with it, she can move very fast in combat. Her weapon of choice is a staff that can grow or shrink to variable lengths, with which she can vault or leap over enemies. When not in use, it is attached to the armband on her left arm.
- WilyKat and WilyKit (Peter Newman and Lynne Lipton) — Twin siblings (Kat the boy and Kit the girl) who are the youngest (in appearance) members of the ThunderCat team, both based on the wildcat. They are the mischief-makers, and often have their own lessons to learn alongside Lion-O while they live on Third Earth, where they frequently use tricks and traps to combat evil. Kat is the more adventurous, while Kit usually errs on the side of caution. Kit also the more agile, and at times employs a rolling-attack against the enemy. Their agility is often displayed when they ride their "space boards" — specially designed flying devices shaped like Earth surfboards that can carry them over long distances. Each uses special capsules, balls and other gimmick weapons carried in pouches and on their belts. They sometimes use slingshots to fire these at the Mutants or other foes. They also carry trick lariats, with which they can either tangle and ensnare foes, or use to pull themselves out of danger. In the first episode they appeared slightly older than Lion-O, and also went into suspended animation. Though they did not age in the suspension capsules. WilyKit is the elder of the twins.
At the start of the series' second season, it was revealed to Lion-O (after having a recurring dream
about the final moments of the destruction of Thundera) that there are three more Thunderans living on Third Earth. They survived the cataclysm when rescued by a Ro-Bear Berbil scoutship piloted by two Berbils. The ship, damaged in the final explosion of the planet, made it to Third Earth, landing on an unknown island somewhere in the northern sea.
After Mumm-Ra tries to capture them to use as bait to destroy the others, these three are rescued and brought back to the Cat’s Lair, where Lion-O anoints them as new ThunderCats. They initially come to live in Cat's Lair, but after the arrival of the Lunataks, they are stationed at the Tower of Omens.
- Ben-Gali (Peter Newman) — One of two younger Thunderans among the trio, named after the bengal tiger but more resembling a white tiger, this warrior is a skilled blacksmith like his father before him. This talent proves valuable after the Sword of Omens is once again broken. Fast and agile like Tygra, Ben-Gali is called ‘brother’ by him, but it is unclear if they share a true familial bond or if the greeting is merely meant as a term of endearment (given that the new ThunderCats repeatedly call the originals "Nobles" while referring to themselves as "mere Thunderans", it seems unlikely that there is any family relationship between the two). Another possibility is that because they are both tigers, the Ben-Gal clan may be cousins to the Tygra clan, even though one is considered nobility while the other is not. In combat, Ben-Gali wields a weapon called the Hammer of Thundera. It can shoot energy blasts, and carries smoke pellets in its handle, to allow him to cause confusion and provide cover for withdrawal from a fight.
- Pumyra (Gerrianne Raphael)— Another female Thunderian — along with Cheetara and WilyKit — this young woman, based on the puma, is a talented healer and medic. She uses her knowledge of Thunderan medicine, combined with the wide range of medicinal supplies to be found on Third Earth, to help heal and cure her fellow ThunderCats. Her compassionate nature lends to offering an alternative perspective, solving problems or conflict without fighting by using compromise and understanding. Possibly the most agile ThunderCat next to the ThunderKittens, Pumyra employs an incredible leaping ability — often able to vault higher than even great jumpers like Tygra or the ThunderKittens. In combat, she uses a special whipcord, which resembles a ‘cat’s tail’, that can launch special pellets and spheres like an ancient sling.
- Lynx-O (Bob McFadden) — The oldest of the trio, based on the lynx, Lynx-O was spared the sight of the destruction of their homeworld by a cruel twist of fate: A blast of intense heat and fire blinded him moments before he and his two younger companions were rescued. Because of this injury, Lynx-O has had to adapt to survive on Third Earth, and has done so by honing his other senses to superhuman levels. His sense of touch, smell, taste and hearing are far above those of the other ThunderCats, and this affords him a type of ‘sixth sense’ (although not like the one Cheetara employs). Though blind, Lynx-O is still a formidable fighter. His sense of touch allows him to find pressure points on a foe’s body to knock them off balance or stun them. He can also feel vibrations, which allow him to evade attacks and capture, and can use a Sonic Reflector as a weapon in combat. His greatest skill comes in utilizing a special "braille board" — a device that allows him to translate information coming from sensor systems inside the Tower of Omens, enabling him to see into the gloom of Dark Side. This same device also allows him to pilot the Thunderstrike aircraft through the Valley of Mists when the ThunderCats need to find a way through to Dark Side.
- Claudus — The previous Lord of the Thundercats and Lion-O's father, Claudus ruled Thundera before its destruction. He lost his sight during a war he fought against the mutants of Plun-Darr. In the episode 'Return to Thundera', Lion-O is transported back in time to Thundera the day before it was destroyed. He later rescued his father from past versions of Slithe and Vultureman, who were attempting to recover plans for a War-Bot that Claudus' Spies had gotten their hands on; he then proceeded to give these plans to Lion-O, who used them in the present to destroy the mutants' War-Bot. Believed to have died on Thundera while assisting the royal flagship in taking off, he was later found to have been captured by the Shadowmaster. Through a sequence of nightmares, Lion-O eventually learns of his father's imprisonment in the Shadow Realm and is able to rescue him.
On New Thundera
When the planet of Thundera is reformed in Season Two of the series, the ThunderCats must work to stabilize the planet before it can tear itself apart again. It is here that they discover another ThunderCat.
- Jaguara (Gerrianne Raphael) — Found deep within the core of New Thundera, this powerful, ancient ThunderCat, based on the jaguar like Jaga, is an immortal sorceress. Her duty is to guard the massive gyroscope that keeps the planet intact. She uses the powers of levitation, teleportation and psychokinesis to perform her tasks, and to defend the gyroscope from attackers. It is noted by Jaga (no relation) that she has been acting in this capacity for countless years.
A race of intelligent cat-like creatures, Snarfs are plump, fuzzy and kind. Snarfs are native to Thundera, living in the Valley of Snarfs, and many of their number act as servants to Thunderan nobility, happily working as cooks, nursemaids, squires and so forth. When Thundera was destroyed, forty-nine Snarfs were able to commandeer a Mutant tanker and made their way to an uninhabited planet which they took as their own, dubbing it the "Planet of Snarfs". Later, when Mumm-Ra recreated Thundera, he captured the Snarfs and brought them back to their home planet, putting them to work searching for the Treasure of Thundera. Subsequently liberated by the ThunderCats, the Snarfs returned to living happily on Thundera.
Snarfs are the only creatures in the universe incapable of evil (except while possessed). Quick and clever, a Snarf is a loyal friend, though their small size often makes them a target for Mutants or other evil creatures. The Snarfs have proved to be valuable allies to the ThunderCats in times of peril. Though their fighting skills are more than wanting, the Snarfs have an inherent invulnerability/resistance to many (but not all) forms of magic and mind-control. This ability has enabled the Snarfs to save the other ThunderCats on several occasions. Snarfs are known to end their sentences with the squeaking exclamation for which they are named - "snarf, snarf!"
In the series, several are named prominently.
- Snarf (Bob McFadden) — An elder snarf, properly known by his name Osbert (which he hates), Snarf served as a nursemaid and protector for Lion-O when he was a boy. After Lion-O grew up, Snarf found that often Lion-O didn’t want to have him ‘mothering’ or protecting him. Still, Snarf has remained loyal to Lion-O and the other ThunderCats. At times, he does come through in a pinch with an idea and takes action when it is needed. Despite his age, he does keep up with the others. Even though not a fighter by skill or nature, Snarf is very agile (he boasts he can outplay anyone at tailbail or kick-the-bucket). He also can communicate with other animals on Third Earth to enlist their help in his tasks and adventures.
- Snarfer (Bob McFadden) — Young and excitable, Snarfer is Snarf’s young nephew. He was thought lost when Thundera exploded, but was one of the surviving Snarfs that made it to the Planet of Snarfs. Slightly more aggressive than his uncle, Snarfer is a keen mechanic and pilot in his own right, having been educated at "Snarf College" (Snarf once said he was a ‘college boy’). He does tend to babble when over-excited, but at times he can be just as level-headed as Tygra. Though smaller than Snarf, he doesn’t let that get in his way when he wants to help friends. It was through him that the ThunderCats learned that Snarf's real name was Osbert.
- Snarf Oswald (Earle Hyman) and Snarf Eggbert (Larry Kenney) — Two of the Snarfs who survived the destruction of Thundera, this duo became the ThunderCats main Snarf "contacts" on New Thundera. Oswald was originally mentioned by Snarf during the first season, noting that he owed him "fifty thunder-dollars."
Allies and natives of Third Earth
- The Ro-Bear Berbils — Partly-furred robot-bears from the planet Ro-Bear. Because their homeworld is so tiny, they must form other colonies on distant worlds to survive. Small and harmless-looking, the Berbils are steadfast, hardy workers and skilled farmers, cooks and craftsmen. It was thanks to them that Tygra was able to build Cat’s Lair — and later the Tower Of Omens — so quickly. Apparently, the Ro-Bear Berbils are Cybernetic organisms, as they are able to eat and digest organic food.
- * Ro-Ber-Bill and Ro-Ber-Belle — Leaders of the nearby Ro-Bear Berbil village, these robot-bears are the first to befriend the ThunderCats and often supply information about local places, people and phenomena on Third Earth. Through their fields and forests of Fruit Trees, they are also able to provide the Thunderians with new foodstuffs.
- The Warrior Maidens — A race of Amazon women who live in the forests of what is called the Tree-Top Kingdom. They are fierce fighters and very territorial. At first distrustful of the ThunderCats — whom they view as aliens — the Warrior Maidens soon treat them as friends. Often, Nayda and Willa are the two that have the most contact with the ThunderCats.
- * Willa and Nayda (both Lynne Lipton) — Sisters, both members of the Warrior Maidens, who live in the Tree-Top Kingdom. Willa is their leader, while Nayda is a scout and second-in-command. Both are expert markswomen with bows and arrows, and are very agile and fleet among the branches of their forest home. Often distrustful of outsiders, both become friends of the ThunderCats and by their example, the rest of their people treat them as allies. They often help the Thunderians by showing them paths around Third Earth and using special tricks (like Bushy, a giant tree-top spider) to aid them on their quests and missions.
- Wollows — Small, furry people who have small villages all around the habitable places of Third Earth. Farmers, carpenters and fishermen, they are gentle folk who often turn to the ThunderCats for protection.
- Bolkens — Sheep-like people, similar to the Wollows. They are herdspeople and farmers, who are just as likely to call for help from the ThunderCats.
- Mandora the Evil-Chaser (Lynne Lipton) — An intergalactic police officer, who works in conjunction with a series of law enforcers to protect the peaceful people of the galaxy. She works in part to run the Great Penal Planet — which houses some of the galaxy’s nastiest criminals — and routinely comes to Third Earth as part of her patrols. When one of these criminals, a robotic pickpocket named Quik-Pik, helps her and Lion-O against Captain Cracker, she makes him an Evil Chaser assistant. She travels on a specially-equipped hoverbike — called the Electro-Charger — and uses a weapon called the “enzyme catalyzer” (a spray gun that uses a chemical — "a closely guarded secret, once called soap").
- Hachiman (Peter Newman) — A samurai warrior and master swordsman from Ancient Japan. Summoned to Third Earth by Mumm-Ra, he was tricked into fighting Lion-O, but thanks to his code of Bushido, he became an ally to the ThunderCats and the Warrior Maidens of the Tree-Top Kingdom. He wields a sword known as “The Thunder-Cutter”, a katana-blade that, with his skill, can cut through solid stone. Hachiman has saved the lives of various ThunderCats on multiple occasions. He is the only character in the entire series whom Lion-O believed could have defeated him in battle (see the episode "Thunder-Cutter"). Hachiman is also the only character to physically battle with the Ancient Spirits of Evil.
- Snowman of Hook Mountain (Earl Hammond) — A yeti-like chivalrous knight, who rules over the Kingdom of the Snowmen on the frigid heights of Hook Mountain. He once tried to fight Lion-O for possession of a meteor that fell onto the slopes of his mountain kingdom, but they became friends after Lion-O rescued him from a Mutant attack. He can craft weapons out of ice, seemingly at will, and fights mounted on a great snow cat, Snowmeow.
- Turmagar (Earl Hammond) — Leader of the walrus-like Tuska Warriors who live near the source of the river that serves as Third Earth’s natural water supply. Very skilled as a warrior and leader, Turmagar is also a crafty pilot who flies the Gomplin, a vehicle/creature hybrid resembling a dragon. It is Turmagar whom often helps the ThunderCats with air support before they crafted their own air-vehicles (it is worth noting that the Tuska Warriors are among the few factions in the series to employ firearms, as opposed to melee weapons and/or bows and arrows).
- Dr. DomeTome (Bob McFadden) — One of Third Earth’s great thinkers, scientists and gentlemen. He is the chief protector of the Great Oceanic Plug, a massive engineering project built to seal a crack in the ocean floor to prevent the planet’s oceans from flooding its core. He is a small man but very chivalrous, and a skilled pilot of Hercules (aka "Herky"), a giant frog-shaped robot used to guard the sea floor.
- Wizz-Ra — A powerful wizard from Ancient Egypt, banished to an alternate dimension after he lost a battle to Mumm-Ra. His helmet has the ability of mind-control and is sought by Mumm-Ra after it’s discovered that the wall of the Seventh Dimension is weak enough (after 7,000 years) for him to appear in Cheetara’s bedchamber. He aids the ThunderCats after they help him to recover his helmet, and then is forced to return to his dimension prison, though not before promising Cheetara they would meet again in her dreams.
- Mumm-Rana — An ancient sorceress for good, and counterpart to Mumm-Ra. She lives in the White Pyramid, where her powers keep her from traveling too far. She at one time battled Queen Luna (grandmother to the Lunitac Luna), to stop her rampage across Third Earth. She did so by stripping Queen Luna of her magical belt, which she later lost to Luna (which was destroyed eventually). Much like Mumm-Ra, her powers limit the time she can spend outside of her pyramid home.
- The League of Third Earth — In season two, once the Mutants, Luanatacs & Mumm-ra had been removed from Third Earth, the ThunderCats left to re-settle New Thundera. They left several of their allies in charge, calling them "The League of Third Earth." This league included, Mandora the Evil Chaser, the Snowman of Hook Mountain and his cat Snowmeow, the warrior maidens Willa & Nada, and the Rober-Berbills: Rober-Bill and Rober-Belle. The Tuska warriors were not included (no reason given) but seemed obvious choices, especially over Mandora, who was not a native of Third Earth and spent most of her time in off the planet.
- Mumm-Ra (Earl Hammond) - The chief villain and antagonist against the ThunderCats, Mumm-Ra is the self-proclaimed "ever-living source of evil" on Third Earth, having powers of sorcery and an apparently unlimited lifespan. He is, in fact, a bound servant to the Ancient Spirits of Evil (represented by four anthropomorphic statues within the burial chamber of his pyramid), who provide him with increased power and virtual immortality to further his pursuit of spreading their dark influence throughout Third Earth.
Residing within the Black Pyramid amid the ruins of what appears to be an ancient Egyptian civilization, Mumm-Ra exists in a decayed, weakened form that must return to a stone sarcophagus to replenish his energy. When leaving the pyramid, he can summon the power to transform himself into a more vigorous form: Mumm-Ra, the Ever-Living by reciting the famous incantation: “Ancient spirits of evil, transform this decayed form to Mumm-Ra, the Ever-Living!” While in this form, Mumm-Ra possesses superhuman strength, the ability to fly, as well as fortification of his mystical might — casting spells, throwing energy bolts, etc. — to battle his foes. He can also alter his physical form into a variety of alter-egos to deceive his enemies.
Seemingly invincible in whatever form he chooses, Mumm-Ra appears to have a singular weakness: seeing his own hideous reflection neutralizes his ability to remain outside the Black Pyramid and forces him to withdraw there in his emaciated mummy form. However, as the second season began, the Ancient Spirits of Evil eventually overcame this shortcoming to make Mumm-Ra even more formidable. Above all, Mumm-Ra is a master of deception, and will use whatever means necessary to fight against the forces of good. Mentioned, in the second episode (and other times through out the series) Mumm-Ra is said to pay a price for leaving the pyramid, but this was never made clear.
In later episodes, while endowing Mumm-Ra with his powers, the statues of the Ancient Spirits of Evil come down from their perches, extend their arms over him as the powers of evil flow into Mumm-Ra.
He also assumes alias forms to deceive the ThunderCats on various occasions. Among these are: Diamondfly (the episode "Queen of Eight Legs"), Gregory Gregion (in the episode "All That Glitters"), Silky (in "The Garden of Delights"), The Netherwitch (in "The Astral Prison"), Pumm-Ra (in the episode "Pumm-Ra"). He once took the form of King Arthur to acquire the legendary magic sword Excalibur, using it against the Sword of Omens.
In several episodes, Mumm-Ra has an even more powerful form beyond "Mumm-Ra the Ever-Living" called "Mumm-Ra the All-Powerful": in this manifestation, Mumm-Ra absorbs the entire power of the Ancient Spirits of Evil to become grander in size and strength, and the design pattern on his loin cloth changes, as does his voice (this form is only presented in the series twice). In another incarnation, calling himself "Mumm-Ra the Dream Master," he is able to enter dreams to subliminally influence the ThunderCats in their sleep as a form of mind control.
Mumm-Ra is regarded as immortal, and when defeated or 'killed', he simply returns to his sarcophagus. Mumm-Ra cannot stay destroyed, as he often states: "Wherever evil exists, Mumm-Ra lives!". Initially, Mumm-Ra cannot stand the sight of his own reflection; if he catches a glimpse of himself he reverts to his mummified form and flees to his pyramid. Eventually however, the Ancient Spirits of Evil rid Mumm-Ra of this vulnerability when they revive him following his failure to harness the power of the Star of Thundera.
Later, Mumm-Ra is shown to have a blue bulldog companion named Ma-Mutt, capable of flight and supernatural feats of strength and speed. He is generally evil, though some episodes depict him as having sympathetic qualities.
An absolute master of both arcane and clerical magic; Mumm-Ra possesses nearly unlimited knowledge of, and experience with, numerous mystical arts from all corners of the universe. As such, he can summon their use to assist him in almost any manner he chooses, most commonly being: flight by self-levitation, necromancy, alchemy, transmogrification, temporal manipulation, teleportation, telekinesis, mind-control, astral projection, scrying, energy blasts.
While in the form of Mumm-Ra the Everliving, he becomes a conduit for the Ancient Spirits of Evil; such that he can amplify his aforementioned abilities to a nearly cosmic scale, gain superhuman strength, as well as retain his undead status despite the passage of time or any injuries sustained. The price of this power however, is extremely limited stamina: once Mumm-Ra the Everliving has surpassed a given threshold of energy-expenditure, he must revert back to his default form, and enter his sarcophagus to rejuvenate himself. It also should be noted that his power in his Everliving form is directly linked to the condition of both his sarcophagus and the Ancient Spirits' four statues within his pyramid; should any of them be harmed or destroyed, his power weakens immediately and considerably.
These creatures are the first villains seen in the series, originating from the planet Plun-Darr. They are the long-time enemies of the Thunderans. Later in the series, it is revealed that events stemming from their invasion of Thundera ultimately lead to the destruction of that planet.
Not content to see the Thunderians lose their homeworld, the Mutants chased after the survivors, using their spaceships to devastate the Thunderian fleet and seeming to destroy the majority of the doomed planet's escaping populace. They then boarded the flagship — which carried the ThunderCat nobles, Jaga the Wise and the young Lion-O — in attempting to capture the Eye of Thundera. They were repelled and retreated to later relocate the crashed flagship on Third Earth.
It was here that Mumm-Ra’s power grounded the Mutant ship, and they were forced to follow his demands once he sank their vessel beneath the desert sands. Though they exhibit an extraordinary incompetence (characteristic of most cartoon villains), the Mutants manage to construct their own fortress called Castle Plun-Darr (named after their homeworld) and salvage equipment from their downed spaceship to build weapons and vehicles that they use on Third Earth (e.g., the Skycutters, the Nosediver, etc.).
The Mutant group is comprised of a diverse mix of races, including:
- Reptilians — Bipedal lizard-men. Their brutish leader, Slithe (Bob McFadden), is the best example of these creatures. Domineering and impatient, Slithe often must browbeat the other Mutants into going along with his plans. It should be noted that unlike Jackalman and Monkian, whose appearances are identical to other mutants of their kind, Slithe stands out from other Reptilians because of his ears. He pilots the Nosediver.
- Simians — Ape men whose leader is Monkian (Peter Newman), a shifty no-good who makes a habit of eavesdropping. He often plays the role of scout for the Mutants, and is frequently the first to run from danger. He pilots one of the Skycutters.
- Jackalmen — Canine scavengers. Their leader is Jackalman (Larry Kenney), a distrustful coward who leaps at taking any advantage he can get — so long as no risk is involved. He most often sides with Slithe, if only to keep from being the scapegoat when plans fail. He also pilots a Skycutter.
Other Mutants are:
- Vultureman (Earl Hammond) — This crafty, avian opportunist is the chief inventor and mechanical know-it-all for the Mutants. His skills with both machines and science make him often indispensable, but he’s more often than not blamed when his devices or machines fail to live up to Slithe’s expectations. Much later, he decides to work for his own gains, and often strikes solo deals with Mumm-Ra. He pilots a vulture-styled Flying Machine, and later commands weapons like the Mutank and Thundrainium Cannon. Unlike the other mutants, Vultureman was not introduced in the opening episode of the series.
- Ratar-O (Bob McFadden) — A General in the Mutant armies, this portly rodent is considered the most cunning and evil of all the Mutants. He comes to Third Earth at the behest of Vultureman to aid them in defeating the ThunderCats. His flagship, the Ratstar, is a powerful war machine, and though it crashes, Ratar-O salvages parts to make a Mutank to continue the fight. He is strong, and wields the Rat’s Eye — a pair of criss-style daggers which have two mystical gems embedded in their hilts — that he can use to fire energy blasts, levitate foes and even fly through the air. Ratar-O resembles Ratilla the Terrible, the former holder of the Sword of Plundarr, but it is unknown if they share a family relation.
Hailing from the Moons of Plun-Darr, these vile beings were once feared criminals in ancient times. They dwell in Dark Side, a volcanic region on the far side of Fire-Rock Mountain. They were encased in molten rock by Mumm-Ra when they attempted to take control of Third Earth. Mumm-Ra later released them on the condition that they work for him to battle the ThunderCats. However, the Lunataks form their own 'third column' based in Dark Side, building a massive, floating fortress called Sky Tomb from which they strike against all of Third Earth. Their numbers consist of:
- Luna (Lynne Lipton) — A diminutive sorceress, now the leader and chief strategist of the Lunataks. Because of her small form, she is carried around and cared for by Amuk, her servant. Cruel and caustic, Luna at one time recovered the magical belt once worn by her grandmother, Queen Luna, and used its power to grow tall and mobile again, but reverted in size when the belt was later destroyed.
- Amuk (Earl Hammond) — Luna’s loyal servant and bodyguard, also her chief mode of transportation. A hulking, dog-like brute having limited capacity for vocalization, Amuk is strong and fast but also displays enough cunning to exact revenge against Luna for abandoning him when she recovers Queen Luna’s magical belt.
- Tug Mug (Bob McFadden) — A Lunatak from one of Plun-Darr’s moons with strong gravity, Tug Mug proves extremely powerful in the lesser gravity of Third Earth. He can use his tripod ‘legs’ to leap great distances, and his strength is so impressive that he once snapped the blade of the Sword of Omens with his bare hands (later repaired by the ThunderCat blacksmith, Bengali). Combative by nature, Tug Mug can use a "gravity carbine" in battle whose beams can make a person or object light as air or as heavy as stone.
- Chilla (Gerrianne Rapahel) — This female Lunatak from the ice moon of Plun-Darr has command over cold and heat by the power of her expelled breath, blowing to freeze the air around a target in seconds to immobilize them, or heating it to incite flames to burn them. She has little regard for life and sometimes uses her powers willfully out of spite. Out of all the Lunataks, Chilla is the most humanoid.
- Red-Eye (Earle Hyman) — A Lunatak from the dark moon of Plun-Darr, this hulking brute has enhanced vision capabilities, allowing him to see things in infra-red and even to detect the ThunderCat Tygra when invisible. A loyal follower of Luna, Red-Eye uses a spinning discus (stored in his armored chestplate) to battle his foes. He is often the engineer and pilot of Sky Tomb.
- Alluro (Doug Preis) — A gangrel-creature with a slimey personality, Alluro is a master of mind-games and psychological warfare. He’s not much of a fighter, but he uses a powerful weapon called a Psyche-Club to immobilize his foes. The crystal ball launched from his club focuses his mental powers onto a foe, allowing him to manipulate their minds with illusions or to command them to do his bidding.
Hammerhand and the Berserkers
This odd band of pirates first appeared pillaging the northern shores of the Unicorn Forest (in the episode The Terror of Hammerhand
). They have a habit of repeating certain words or phrases three times. The original Berserkers were apparently all killed when their ship was sank, but Hammerhand was later mystically resurrected by Mumm-Ra, who summoned up his spirit to animate a clone of Panthro which he had created. When the plan failed, Hammerhand's spirit broke Mumm-Ra's control, and the clone body shifted into Hammerhand's original form before departing. When he next appeared, in the Season 2 mini-series, "ThunderCats-Ho!", Hammerhand had reformed the Berserkers with new members endowed with cybernetic bodies and powers like his own. The Berserkers are:
- Hammerhand (Earl Hammond) — The leader, who has a cybernetic arm that can punch and pound with great force.
- Topspinner (Bob McFadden) — A warrior who can spin at high speeds to deflect missile objects or smash opponents. His spinning can also make him dizzy.
- Ram Bam (Peter Newman) — Rolling by the wheel embedded in his chest, this fighter can launch himself along the ground at high speeds to smash through objects like a battering ram. He also has rollers on his feet to help him move fast.
- Cruncher (Earle Hyman) — A hulking pirate whose sheer strength can crush buildings and boulders with ease.
- Grune the Destroyer (Bob McFadden) — An anthropomorphized saber-toothed tiger in appearance, this former ThunderCat noble was once a good friend to Jaga the Wise on Thundera. His lust for power and greed turned him renegade against his fellow ThunderCats, forcing Jaga to fight him in a titanic battle that lasted for days. Grune was defeated by Jaga, then banished and sent into exile in space.
Eventually his spacecraft landed on Third Earth and he began terrorizing its natives until, many years later, he was defeated (by unknown means) and sealed away inside a tomb (which was covered with a stone slab and a tree to prevent others from opening it). A tablet held the seal in place, until centuries later, a pair of Bolkens accidentally released his spirit. Once freed, the ghost of Grune seeks out the ThunderCats, attacking them to draw out Jaga, whose spirit ultimately defeats him using both Lion-O’s strength and the Eye of Thundera.
However, Grune would return later when summoned by Mumm-Ra to stop Jaga’s spirit from obtaining the Star of Thundera (which was needed to help free three more Thunderians — Pumyra, Bengali and Lynx-O — from the Mutant prisons at Fire-Rock Mountain).
When the ThunderCats return to New Thundera, Grune is resurrected by Mumm-Ra. Grune is initially successful against Lion-O, breaking the Sword of Omens and chaining Lion-O and Cheetara up on the Churning Rocks. However, Snarf gathers the pieces of the sword and while attempting to take them to Bengali for repair, he is captured by Char, who repairs the sword, wanting to keep it for himself. Sensing the sword is repaired, Lion-O calls for it and uses it to free himself and Cheetara. Grune attempts to defeat Lion-O, but fails and is banished back to Third Earth.
- Safari Joe (Larry Kenney) — An intergalactic big-game hunter (with an Australian accent) who ventures to Third Earth to hunt the ThunderCats. He uses a rifle that has a variable arsenal of weapons (capture claws, fire rounds, missiles, etc.), and has a robot assistant named Mule (whose head is shaped like a train) who helps to assemble traps, using a computerized analyzer to provide information on his prey. Safari Joe manages to capture all the ThunderCats and imprison them in cages made of thundranium, a substance that weakens ThunderCats. Safari Joe fails to capture Lion-O thanks to Snarf supplying a distraction. When Safari Joe finds himself out of ammunition, he is revealed to be nothing more than a coward. Safari Joe was made to promise that he would never hunt again, and Mule was reprogrammed to ensure he kept his word.
- The Demolisher (Peter Newman) — Only appearing in a single episode, Demolisher is one of the more powerful foes to challenge the ThunderCats. Similar to Safari Joe, his motives are not power but glory. A dog-like being, the Demolisher travels from planet to planet seeking a worthy opponent to battle with his arsenal of high-tech weapons. The Demolisher travels with his stumpy, drummer companion "Dirge" who serves the role of a cheerleader/herald and is somewhat of a 'Snarf' to Demolisher's 'Lion-o.' Demolisher originally lands on Third Earth to battle Mumm-ra. Mumm-ra is defeated by the galactic warrior but convinces him that Lion-o is a far worthier conquest. Demolishers seeks out and engages Lion-o in battle but is eventually overcome. Defeated, Demolisher flees Third Earth in shame, Lion-o laments that such a strong & courageous warrior must live without a cause to fight for, stating "..I wish he had joined us in our fight to spread the code of Thundera."
- Captain Cracker (Earl Hammond) — A robotic space pirate who captains a starship named the Jolly Roger. He raids the Great Penal Planet to release a criminal contingent to help him take over the space-ways. He has a robot parrot named Polly.
- Captain Shiner (Bob McFadden) — A monocle-wearing, doglike space-faring alien mercenary commanding a starship named The Vertus and its sizeable crew. He is summoned on more than one occasion to carry out Mumm-Ra's bidding (for a substantial fee).
- Mongor (Bob McFadden) — A demonic goat-like being believed to be the personification of fear on Third Earth. For three centuries, Mumm-Ra had unsuccessfully tried to locate his tomb and free him, but the Thunderkittens accidentally freed Mongor, allowing him to attack and subdue the other ThunderCats. He feeds from his opponents' fears to grow larger and more powerful. His only weakness is for his foes to not look directly at him, which takes away his power (as Lion-O, Wilykit and Wilykat discover to defeat him).
- Driller (Bob McFadden) — A metallic humanoid being who has a drill in place of legs. He also has changeable drill bits on his head, which allows him to drill through the sand, rock and dirt in the deep desert. His services are for hire; his chief price is diamonds, which he needs to keep his drill points sharp. He once captured Panthro for Mumm-Ra, and appeared again to drill a tunnel from Acid Lake to the Cat's Lair. Driller starred in three episodes.
- The Shadowmaster — A wizard on Thundera who used a cloak of darkness to conjure his magical powers and attempted to take over the planet. He was defeated by both Jaga and Lion-O's father, Claudis, and was then banished to the 'Shadow Realm', but he managed to escape years later, kidnapping Claudis just before Thundera was destroyed. Through a sequence of nightmares, Lion-O eventually learns of his father's imprisonment in the Shadow Realm and is able to rescue him. Shadowmaster has arguably come closer to defeating the ThunderCats than anyone else. In his one-time assault on the ThunderCats, Shadowmaster would have succeeded had Mumm-ra not interfered for fear that Shadowmaster would replace him as the chief servant to the Ancient Spirits of Evil.
- Zaxx-A four-armed avian sorcerer who unsuccessfully fought Mumm-Ra for control of Third Earth in the distant past. Zaxx was left without form as his essence was trapped within a magical medallion; any creature later wearing the medallion acquires his fantastic power but is progressively transformed to permanently become Zaxx, who requires a host body for retribution against his ancient foe.
- The Mad Bubbler- A reptilian phantom that inhabits the Hook Mountain thundrylium mines. Bears an uncanny resemblance to the bubble dragons from Bubble Bobble.
Despite its large cast of characters, ThunderCats
featured a rather small circle of voice actors, with only six actors providing voices for the entire first season. Every actor provided multiple voices, although the incredibly distinctive baritone of Earle Hyman (Panthro) left the actor providing only very occasional guest voices in comparison with his fellow performers. In particular, as the first season's only female actor, Lynne Lipton (Cheetara and Wilykit) provided voices for every single female character that appeared in the season. Above all others, however, actor Bob McFadden would most regularly provide the voices of guest characters, with his two diametrically-opposed main roles - the timid, high-pitched Snarf and the rumbling, sibiliant Slithe - showcasing the variation that ensured he was up to the job.
Despite introducing a large number of new regular characters, the show's second season brought in only two new actors. Gerrianne Raphael provided the voice of Pumyra, and was able to provide Lynne Lipton with some relief by added new female voices. Conversely, actor Doug Preis is regularly credited on the Internet as the voice of Lynx-O, but this is incorrect - it does not take a particularly alert ear to recognise Bob McFadden providing Lynx-O's vocals. Preis, it would appear, is the voice of Lunatac Alluro, the only member of the cast who does not appear to be voiced by any of the first season cast members.

Action figures and other merchandise
produced the ThunderCats action figures
from 1985–1987. The ThunderCats line was based on the animated series which was actually created in 1982. Due to difficulties, it wouldn't air until 1985. Each figure had an action feature of some sort, and the line also included a unique "laser" light-up feature that interacted between the Cats Lair playset, some figures, and some accessories. Lion-O's head and Mumm-Ra's eyes would illuminate when a special key ring that came with the figure was pressed into a slot in their backs. PVC companions were packaged with some figures in 1986, including WilyKat with Tygra, WilyKit with Cheetara, Snarf with Lion-O, and Ma-Mutt with Mumm-Ra. The PVC companion figures were also produced as full size articulated figures.
LJN did produce a few variant figures including the young Tygra version and the silver rat-eye daggers for Rataro. There are also a few slight color variations of Lion-O, such as red and orange-haired versions. The third series of figures from 1987 are harder to find along with the Tongue-A-Saurus and Astral Moat Monster. Driller and Stinger are the toughest figures to track down; Stinger's wings are very fragile, making it next to impossible to find a loose, complete figure.
An unproduced final series of figures would have included The Mad Bubbler, Redeye of the Lunatacs, Cannon-Blaster, and Quick-Jaws from the Bezerkers as well as the Feliner, Thunderstrike, and Luna Tacker. The Mad Bubbler is rumored to have been produced, but this has yet to be proven. Photos of these were featured in the 1987 LJN catalog.
In 1987, Elite Systems released the game , for Commodore64/128 and Sinclair ZX Spectrum personal computer systems. Many years later, Cartoon Network's official website featured a game that allowed visitors to play as Lion-O and rescue fellow ThunderCats while venturing into Mumm-Ra's tomb.
Other ThunderCats merchandise of the 1980s included, among other items, a board game, TV tray, tin lunchbox, and apparel. A retro spurt occurred in the 2000s which saw a handful of new ThunderCats items like T-shirts and sweatbands make their way to shelves.
There is currently an online petition to get Warner Bros. to release an official soundtrack containing the music from the series, which was written and performed by Bernard Hoffer. The petition can be found at http://www.thundercatsfans.org/tcfans/petition/index.php
In 1985, a ThunderCats
series was published by Marvel Comics
through its Star imprint. It ended with issue #24 in 1988. The following year, a new series was published by Marvel UK
. The series consisted of 129 issues and was published for three years.
In 2002, DC Comics, owned by Warner Bros. (who acquired the rights for the franchise due to its 1989 purchase of Lorimar-Telepictures), published a ThunderCats sourcebook through its Wildstorm imprint. In 2003, a wave of mini-series and one-shots were published.
The original mini-series, Reclaiming Thundera (written by Ford Gilmore with various artists contributing), published in 2003, formed a series of loosely connected "episodes" that saw Lion-0 continue his struggle against Mumm-Ra and The Mutants, a major plot point was the slow corruption of WilyKat by Mumm-Ra, which would play a major role in later storylines.
After another fateful battle with Grune, Lion-O entered the Book of Omens to begin his training and claim his rightful place as Lord of the ThunderCats, but Mumm-Ra uses a powerful spell to keep Lion-O trapped in the book for several years in real time, not "Book" time, and seizes control of Thundera afterwards.
In the follow-up mini-series The Return (written by Gilmore, and illustrated by Benes, Pimental, and Lea), Lion-O returned to Thundera to find it enslaved to Mumm-Ra. Several of the ThunderCats are scattered, held prisoner, or enslaved to his enemies. This storyline was distinctly more mature than many episodes of the series, with much harsher language such as "Bastard" used by Mumm-Ra. Cheetara is depicted as holding a grudge against Lion-O for "abandoning" his friends for such a long time, and WilyKat's corruption in the earlier mini-series takes greater form. Realizing he has betrayed his friends, the older Cub flees when the mini-series concludes, Lion-O and the ThunderCats emerge triumphant over Mumm-Ra once again.
By the third mini-series, The Dogs of War, (written by John Lyman, illustrated by Vriens, Heling and Campus of Udon Studios) many years have passed and Thundera has prospered. Lion-O is now an aged and experienced commander of his countrymen. An invasion of Dogstar forces ultimately lead Lion-O to ally with Mumm-Ra himself (when Ma-Mutt even turns against him). Along the way, WilyKit finds true love and WilyKat redeems himself. The storyline concludes with Mumm-Ra offering Lion-O an elixir of youth so that they may continue their struggle against one another.
The remaining mini-series were all prequels, set during the events of the animated series. These were "Hammerhand's Revenge" (written by Fiona Avery, illustrayed by D'Anda, and Enemy's Pride, (written by Layman and illustrated by Virens, Hellig and Campus), which was published in 2004.
Several one-shots were also published. Two crossovers with Battle of the Planets, one crossover with Superman, and three "Origins" issues that established more of the backstories. These were published in 2003 and 2004.
In 1986, ThunderCats - HO The Movie
was released on VHS in the UK and North America. It was later edited into the five episodes which ultimately led to season 2.
Warner Bros. is in the process of creating a CGI animated film based on ThunderCats. It will be an original story expanding on the events of the first episode. Expected release circa 2010.
