#336
Fang Snake Pokémon
Seviper is a Poison-type Pokémon, No. 336 in the National Pokédex, introduced in Generation 3 (Hoenn region).
« Seviper’s swordlike tail serves two purposes—it slashes foes and douses them with secreted poison. This Pokémon will not give up its long-running blood feud with Zangoose. »
Seviper is a snake usually bunched up like an accordion. Black scales with yellow hexagons, purple scar-like marks, long red fangs, and a tail that ends in a blade.
It wraps a foe so it cannot move, then poisons it with its tail and fangs. A bitter enemy of Zangoose, it lives in grasslands and savannas.
Jessie makes it her main partner in place of Arbok. Before Unova, she leaves it at Team Rocket Headquarters so an outsider Pokémon will not draw notice.
It suggests a viper, especially the habu. French Séviper may blend “sévir” and viper; English Seviper blends sever or serpent with viper, its S mirroring Zangoose's Z.
