I'm glad you brought that up. The debate on the issue of Claws vs Armor has been ongoing since the beginning. Granted this is the Ultimate version, but every other attempt Wolverine has made at slicing through Colossus in either (Universe) has caused nothing but sparks. And this one appears (from the picture) to show him having only steel skin, while the originals entire organics are composed of steel. If this Colossus dies (though I hope he doesn't) I don't know if I'll be as upset as when the Original did. Especially seeing as how the true Colossus (as I refer to him) sacrificed himself for the greater good, while this one seems to be a bitter, cynical, perhaps even self loathing A-hole who gets murdered by his own team-mate. Come to think of it very few of these X-men are likable in contrast to their original counterparts. They just don't exude that sense of heroism, at least to me anyway.
