Colossus (Piotr Rasputin) is a gentle Russian farm boy who can transform his entire body into organic steel, making him virtually indestructible and superhumanly strong. Created by Len Wein and Dave Cockrum in 1975, Piotr is the X-Men's gentle giant — a painter and artist whose massive armored form belies a deeply compassionate soul. His combination of immense physical power and tender humanity makes him one of the most lovable members of the entire X-Men roster.
