- In episode 103, Yugi Muto and Yami Yugi face this monster in a door puzzle. Yugi Normal Summons "Swift Gaia the Fierce Knight" without Tributing via its own effect and uses it to attack this monster, but the door activates "Mirror Force" to destroy "Swift Gaia the Fierce Knight". After Yugi Normal Summons "Gazelle the King of Mythical Beasts", this monster reveals itself. The door then equips this card with "Sword of Dark Destruction", increasing its ATK by 400 and decreasing its DEF by 200. Yugi then activates "Polymerization" to fuse "Gazelle" with "Berfomet" in order to Fusion Summon "Chimera the Flying Mythical Beast". "Chimera" then attacks and destroys this monster.
