- In episode 117, Thelonious Viper uses this card during his duel against Jaden Yuki. After he summons this card, Viper activates this card's effect to place a Venom Counter on "Elemental HERO Clayman" at the cost of forbidding this card from attacking this turn. In the next episode, "Elemental HERO Plasma Vice" attacks and destroys this card. Viper then activates "Snake Whistle" and "Damage = Reptile" to Special Summon "Venom Serpent" and "Venom Boa" respectively. Later Viper discards another copy of this card in order to activate "Snake Deity's Command" and give Vennominon 500 attack points. Later Jaden activates the effect of "Elemental HERO Marine Neos" to destroy one card in Viper's hand and Viper reveals it to be this card. This increases the ATK of "Vennominon the King of Poisonous Snakes" by 500. "Marine Neos" then attacks and destroys "Vennominon". Viper then activates the third effect of "Vennominon" to banish one copy of this card from his Graveyard and revive "Vennominon". In the following episode, Jaden activates the effect of "Necro Shot" three times to banish one copy of this card and two "Venom Serpents" from Viper's Graveyard and decrease the ATK of "Vennominaga the Deity of Poisonous Snakes" by 1500. After that resolves, "Necro Shot" is destroyed. "Elemental HERO Darkbright" then attacks and destroys "Vennominaga". Viper then activates the third effect of "Vennominaga" to banish this card from his Graveyard and revive "Vennominaga".
