Sevastase vs. Avesher would be an interesting fight.
Although SpermBallsTaste = a delusional moron, he would probably win as he has experience from Kyoshinkai Karate, sparring experience in boxing (or something like that), and he has the strength advantage (if he bothers to go to teh gym for a few months) + speed advantage.
Avesher really only have some weight advantage, and he = nuts (but so is SpermBallsTaste).
