From Bulbapedia, the community-driven Pokémon encyclopedia.
Tyson (Japanese: タツミ Tatsumi) is a high-ranking officer of Team Rocket.
Tyson is somewhat coarse, but not overly rude. A reserved opportunist, he grabbed the three most useless agents he could find—Jessie, James, and Meowth—and tricked them into a most dangerous job by giving them free food. He also has a thing for making bad jokes off and on. He was arrested along with some other Rocket Grunts in the ending of Rage Of Innocence.
