Id like to see Gorgon win, but I'm not sure if he can. If his tp is strong enough to defend against Sinister's tp.....he wins. If the battle gets physical in any win....Gorgon stomps. But if it stays at a distance and Sinister is able to use his ranged attacks wisely, he can take a slight majority.
Gorgon is really durable though. So it's not a given that Sinister can win even if he uses his ranged attacks.
