First off, what kind of bullshit is this that Rogue beats Carnage? It took Spiderman, Venom, and the entire freakin fantastic four to take him down. One little girl who steals others powers isnt going to kill the strongest symbiote ever.
Also, whoever said Silver Surfer was the strongest, Id like to see him take on Marvel Powered Spiderman.
Anyways-
Spawn
Batman- Hes taken on ol' Freezy many times, i dont think Iceman would be much different.
Rorschach- Sadly, I just cant vote for Hellboy after the Watchmen trailer
Green Lantern- Is completely BA
Justice League
Green Lantern Corps.
