Strong. Unstoppable. Stepped on by a Sentinel. That's Colossus in X-Men: Days of Future Past. Daniel Cudmore reprises his X-Men: The Last Stand role as Russian mutant Piotr Nikolaievitch Rasputin in this upcoming franchise sequel. 20th Century Fox is continuing its daily debut of character portraits leading up to the film's summer release (or perhaps a new trailer). Check out Piotr in his human form, before he transforms his skin into an organic steel-like substance that grants him superhuman strength. Will he be able to defeat the Sentinels? Or is this one mutant Wolverine will have to save when he is transported back in time to stop the mass Mutant genocide that takes place in the future?
