Butch

Butch (コサブロウ Kosaburō) is an agent of Team Rocket who appears in the Pokémon anime. Like his partner Cassidy, he is fairly arrogant, and has a bitter rivalry with fellow Team Rocket members Jessie and James. Between him and Cassidy, Butch does more of the heavy duty work, such as driving or carrying, while Cassidy tends to boss him around a little. As a running joke, none of the other characters seem to remember Butch's name and always address him by the wrong names, which irritates him to no end.
