Yes, it's Colossus in the flesh (as opposed to "organic steel"). His powers have been neutralized by Kruun,, who wants to trow down with a depowered Piotr in Uncanny X-Men #537. I've always thought Piotr looked great in his steel form, but he's way hotter when he's just flesh and blood and clad in nothing but boxers. Many thanks to our old pal, Tranetrax. who sent in these scans.
