In episode 21, this card appeared while Jaden was rebuilding his deck.
In episode 46, Jaden uses this card during his duel against Amnael. He equips this card onto "Clayman". Jaden then activates "Polymerization" to fuse "Clayman" with "Burstinatrix" in order to Fusion Summon "Rampart Blaster". Since this card was sent to the Graveyard, its effect activates, allowing Jaden to destroy "Elemental Absorber".
In episode 105, this card appears in a flashback Jaden has when he notes that even though he lost to Aster when the latter used his real Deck, it gave him the chance to see the Neo-Spacians who later became his friends.
