Yajirobe

Yajirobe is the most useless of the Z warriors. He occasionally comes in handy, shuttling information and Senzu beans from Korrin, but for the most part is basically a ravenous, lazy, crab of a man. He is never very pleasant, and isn't thought of with fondness in any of the Z warriors' hearts. He does prove useful in the battle with Vegeta, however, cutting off the Saiyan's tail and distracting him long enough to give the others another chance.
