Deadpool creator Rob Liefeld admits big presence of Colossus
During a Q&A session, the amazing Hawaii Comic-Con responded frankly about the long-awaited Deadpool and the Colossus factor. Rob Liefeld had this to say about the inclusion
“You guys have seen a glimpse of him in the trailer; at San Diego in Hall H, they showed a little bit more of Colossus. You are going to love Colossus in Deadpool. He’s in it a good amount; he doesn’t just walk through the movie.”
Pitor Rasputin is one of the most powerful X-Men to ever fight for Professor Xavier with the ability to transform his body into organic steel. This well-liked "˜Colossus' was originally played by Daniel Cudmore in X2: X-Men United. He was offered to play the same in Deadpool and while that was not the case the character is now actually protrayed by Andre Tricoteux.

According to CinemaBlend, Rob Liefeld also told the eager fans that while Deadpool is very much a distillation of the core traits of its titular character, they should not expect a direct adaptation of any specific storylines because Deadpool and Colossus do not have a rich history of stories together to draw from.
