Pardon me sirs, but Knuckles is a guy, right? He's naked besides his shoes and gloves, right? Everyone knows he's a guy, but the creator didn't draw a penis on him or anything. Everyone just assumed he was a guy be his attitude and kewlness. Same goes for Yobo. He has long, SS3-like hair, and he's not even a human, so he shouldn't wear clothes. I dont think I need to draw a dick on him so that you know he's a guy.
