my favorites are:
Yamcha
Mecha Frieza(heck, frieza in general)
Piccolo
Yamcha just because he is awesome and I have pretty much ,astered being him on different games, Frieza because no matter what I can kill all!!! and of course Piccolo because he is a suoer Namek, and super easy to use and has some of the best moves
Thank you so much Espeon Dude!!!!!!
Jason beat him. He's the best.
