Colossus

Piotr Rasputin is a big man before he goes into metal form, standing six feet six inches, and over 200 pounds! He can then turn his skin into organic steel, and gains one foot and one inch in height, and nearly 300 pounds. Colossus first appeared in the Giant Size X-Men box set, along with Cyclops, Wolverine, Storm, Nightcrawler, and Thunderbird. His figure was then not released for several years, up until recently, when the Juggernaut version was made, and also 2 classic versions. No versions of his ultimate, Acolyte, or any other variants have been made yet.
