The third piece of the Amulet, the top point of the artifact, was revealed to be in the possession of Lady Illusion (although not many people took it into account and mistook it for Lord Fear's piece of the Amulet). She gave it over to Lord Fear willingly. The fourth fragment was discovered by Dirty Rat, who had picked up its unique scent and found it by digging underground. Lord Fear used it to summon Googler from White Hot Oblivion.
Several days on, Dirty Rat came up with a devious plan. He stole Mark's and Lord Fear's pieces of the Amulet and connected them, summoning Random Virus. Ace later detected the fifth fragment, located in a claw machine in a jar. While Ace was losing to Lord Fear and Anvil, Mark worked the claw machine and obtained the fragment, summoning Sparx to Earth. Sparx was later destroyed by Googler and sent back to the game.
Ace had developed a hatred for garden gnomes and destroyed one outside Duff Kent's trailer. Interestingly enough the sixth piece of the Amulet was located inside to Ace's delight and he slowly searched for Mark, finding him at a campsite. The two connected their fragments and Sparx made her return.
The final fragment showed up in Episode 24, hidden in a prize box at the carnival. Lady Illusion, disguised as a carnival worker, was stunned when the piece was picked up by Samantha. Lady Illusion and Dirty Rat tried to get it back but failed too. Lord Fear heard what happened and went with Dirty Rat to get the piece from Samantha, who was in the school play. Lord Fear got caught up in the play, starting to play the organ and forgetting all about the fragment. Dirty Rat, however, scooped up the fragment and plotted to use it to overthrow Lord Fear.
The next day, Sparx was captured and had Dirty Rat guard her. With prodding from Sparx, Dirty Rat got the other minions together and they revolted against Lord Fear and started to chase him. Meanwhile, Lady Illusion was sent by Staff Head to get the rest of Ace's pieces of the Amulet, presumably getting those from the Thunder Tower and then obtaining Mark's while disguised as Sparx. Lord Fear obtained those pieces and managed to persuade Dirty Rat to rejoin him and gained the final piece of the Amulet.
Now that Lord Fear had the Amulet, the Lightning Knights slowly started to lose their powers. Mark explained from the rulebook that they would now have to fight the villains and get the Amulet back, but if any of their energy dropped below 12%, they would die. Ace, Sparx and Random went to the Carnival of Doom and did battle with the villains, but were losing badly. Mark sneaked into the haunted house and tried to beat Lord Fear in his game, but lost. He then realised the Amulet was hidden in Lord Fear's organ. After playing the right notes, Mark obtained the Amulet and shattered it, automatically winning the game and killing Lord Fear and his gang.
Lady Illusion found another fragment the following day that was hidden in a prank snake jar. Lord Fear summoned Anvil back from the game. Soon on, Lady Illusion found a fourth piece by shattering a vase in Mark's house. However, this was the last piece she would retrieve in her guise as Felicity. Ace Lightning appeared and for a long time decided not to obtain any more pieces of the Amulet.
He and Dirty Rat retrieved the fifth fragment from Mark's backyard by digging up the garden, and Lord Fear used it to summon Pigface back from the game. Lady Illusion obtained the sixth fragment at the carnival when Mark left his bag unattended and Lord Fear used it to summon Googler back, completing the villains. The final fragment was obtained by Kilobyte when he ambushed Mark at the carnival. However, Kilobyte was destroyed by Lord Fear, Mark and Lady Illusion disguised as Ace. The Amulet was shattered by the blast and the pieces flew off.
The cancelled Season 3 would have featured the Amulet again, but Lord Fear would not possess it as he was on the run, and would try to use Mr. Cheseborough's technology to summon his minions back from the game.
Season Two involved the fragments hidden in and around Mark's house. Lady Illusion infiltrated her way into Mark's house, disguised as a housekeeper called Felicity Fury. She obtained four pieces before her guise was revealed to be a fake. These pieces were hidden in Mark's bedroom and in a vase in the house's living room. The fifth fragment was obtained by Kilobyte and Dirty Rat by digging in Mark's backyard. The sixth fragment was found by Lady Illusion when she looked in Mark's rucksack. The seventh piece was gained by Kilobyte in the final episode. Kilobyte completed the Amulet but before he could use it, he is blasted back to the Sixth Dimension and the Amulet shatters again.
