From Bulbapedia, the community-driven Pokémon encyclopedia.
Howie (Japanese: ヒロヲ Hiro'o) is a character of the day who appeared in The Ole' Berate and Switch!. He is a Trainer from Sable City.
He was the first Trainer that Ash and his Corphish battled in a fake tournament organized by Team Rocket agents Butch and Cassidy.
Howie's Pinsir battled well and used Vise Grip, Guillotine, and Seismic Toss to weaken Corphish, but when his second Guillotine failed due to Corphish using Harden and then Bubble Beam, he lost.
