Actually, aside Gatsu. I think Vegeta, Tien, Android 17 & Super C17 would be my other favorite anime characters...
The design for Super 17 was bad ass... I remember I used to be addicted to him when I was playing ESF... I kept requesting a Android 17 or Super 17 player model but no one wanted to make one :\
I also used to like Tien next to 17. I remember a while back there was an arguement in this forum over who was the best Human... Everyone knew Tien was the man, newbs kept saying it was Krillin :\ Tien is the man
I ended up liking Vegeta more than Gokou after more about his Ego/Pride is revealed throughout the DBZ Series. Plus everyone knows he was the **** in the Saiyan Saga.
