Iron Man: Tony's cool; just as long as he's not the Silver Centaurion or the Golden Avenger.
Savage Hulk: Greatest character ever. (I loved the Hero's reborn artwork. Didn't care for the fact that Hulk was stark naked.)
Thing: Original "Clobberin' Time" Ben.
Superman: Superman as a herald.
Colossus: How many versions are there?
Wolverine: Ditto?
Thor: Heroes Reborn.
Spiderman: Cosmic Spiderman, (Spidey with the Captian Universe power,) kicked ass.
Iron man?--His Thorbuster armor looked kind of dorky, but was badass, nonetheless. The XCON ceramic armor was cool too.
Hulk?--Peter David's Hulk. Brutish, but more on a bully level. He interacts with Banner and doesn't have a three word vocabulary.
Thing?--Classic Thing
Colossus?--Same as Thing
Wolverine?--AOA
Thor?--King Thor, because he had a cool looking helmet.
Apocalypse?--don't care
Captain Mar-vell?--Kree Uniform Genis
Superman?--MULLET!
Spiderman?--Scarlet Spider
