Card Appearances:Doom Virus Dragon
- In episode 150, Seto Kaiba uses this card during his Duel against Alister. He Special Summons this card by merging "Fang of Critias" with his set "Crush Card Virus". Kaiba then activates this card's effect to destroy Alister's two "Blue-Eyes White Dragons" (who Alister took control of via "Fire Whip") and "Gorlag" (as their ATK were at least 1500). This card then attacks directly, but Alister activates "Contagion of Madness" to inflict half the damage he takes to Kaiba. This caused the Duel to end in a DRAW.
