Card Appearances:Armityle the Chaos Phantasm
- In episode 130, Marcel Bonaparte uses this card during his Tag Duel against Jaden Yuki and Jesse Anderson while the former was possessed by Yubel. He Special Summons this card via "Dimension Fusion Destruction". Yubel, at this point, regains her physical form and takes over in Marcel's place. She then activates the second effect of this card in order to inflict 10000 Battle Damage to "Elemental HERO Chaos Neos", but Jesse activates "Prism Wall" to redirect the effect to "Rainbow Dragon". Jesse then activates the first effect of "Rainbow Dragon" to send "Crystal Beast Amber Mammoth", "Crystal Beast Topaz Tiger", "Crystal Beast Emerald Tortoise", "Crystal Beast Cobalt Eagle", "Crystal Beast Sapphire Pegasus", and "Crystal Beast Amethyst Cat" to the Graveyard and increase the ATK of "Rainbow Dragon" by 1000 for each Crystal Beast sent to the Graveyard to this way. With six sent this way, "Rainbow Dragon" gains 6000 ATK, allowing it to survive this card's effect. The last effect of "Prism Wall" then activates, inflicting damage to Yubel and Jesse equal to the new ATK of "Rainbow Dragon" and defeating both of them. The attack between "Rainbow Dragon" and this card is so powerful that it is enough to create a portal to return Duel Academy to Earth. Jesse tells Jaden to go on without him as he needs to keep the portal open long enough for Duel Academy to be transported back to Earth.
- In episode 131, this card is shown in a flashback Jaden has when he remembers that Jesse stayed behind in the alternate dimension so that he could keep the portal open long enough for Duel Academy to return to Earth. Jaden then realizes that what happened was his fault as he was the one who sent Yubel to space, which caused the chain of events to occur up until now.
- In episode 132, this card is shown in a flashback Jaden has when he notes he is positive that Jesse is alive somewhere in the dimension that he (Jaden) is in.
- In episode 149, Jesse uses this card during his Duel against Adrian Gecko while the former was possessed by Yubel. He summons this card via "Dimension Fusion Destruction". Jesse then activates this card's third effect to switch control of this card to Adrian. On Jesse's End Phase, this card's last effect banished "Exodius" and returned itself to Jesse's side of the field. In the next episode, "Fog King" attacks this card. Adrian then activates the third effect of "Fog King" to reduce both battling monsters' ATK to 1 during the Damage Step only. Adrian then activates the first effect of "Fog Castle" to move his monster to a different Monster Card Zone, place a Beacon Counter on "Fog Castle" and prevent "Fog King's" destruction, however he loses a Monster Card Zone. "Fog King" then destroys this card as "Fog King" negates the effects of all other monsters on the field.
- In episode 153, this card appears within a series of flashbacks Jaden has when he wonders if he will have to use overwhelming force to defeat Yubel. Jaden notes he can't take more sadness, so he will have to throw away all of his pity toward Yubel and use the power of the Supreme King.
- In episode 175, this card appears in a flashback Jaden and Jesse have when Jaden reminds Jesse it has been a while since they fought in a Tag Duel together.
