Seviper first appeared to defeat Team Rocket and its Poison Tail proved to be stronger than the Poison Tail used by Jessie's Seviper. After defeating Team Rocket with Flamethrower, Seviper was used to battle Ash's Donphan when Ash challenged the battle pike. Seviper put up a good fight but was defeated when Donphan rolled straight into Seviper's Flamethrower creating a flaming Rollout attack (basically a Flame Wheel although this could not be learned by Donphan) which defeated Seviper.
