OK, this is really crossing the boundaries of Marvel due to the fact that Colossus in Deadpool is always in metal form, but in Deadpool Colossus seems to have dents in him. I never thought he could have been dented permanently as Colossus seems to have in Deadpool.
Dent in his left arm,
I know in the comics that he has his bent and broken by "World Breaker Hulk",
But, there is not much on if dents will stay with him. Contrary to the comics and other Marvel movies Colossus does not change into human form in Deadpool, so I can only imagine that he has an injury of some sort to keep that dent???
