The Z fighters are all the Earth's strongest warriors. So he like, how many of them are there now? Eleventh strongest person on earth. That talking cat is a fiercely loyal friend. He did pretty well with the ladies during his stint as a baseball player. All in all, actually, Yajirobe is the worst. Unless you count Vegeta and the countless planets he destroyed which makes him like a mega hitler x9001, but I like the series better while he's still a bad guy and not one of the Z fighters...
