Tyson (in Japanese: タツミ, Tatsumi) was a high-ranking Team Rocket agent.
In English version he was voiced by legendary voice actor Dan Green. In Japanese version he was voiced by Yoshinori Sonobe.
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.
