The main thing they need is to get Drug Control in there to get these guys off their steroids! Character design is an abomination IMO. It's like they took one oversized muscle-man model and stuck different heads on it. The result is boring.
Well with the latest new character unveiled, Abel, these muscular characters are no accident. Abel is copied straight out of Baki, so it is clear to me now that the look most of the original world warriors too are inspired by Baki in SF4.
I still prefer their inspiration from Hokuto like previous SF games. At least with Hokuto, the height and head ratio kinda balance them out a little.
Just look at Feng from Tekken 5, that one is copied straight out of Baki too. He was rather muscular too. Heck check out Baki fighting game, the characters are like these too.
