Commonly got wrong

Claims that are widely repeated and wrong, with what the cited record actually shows. If you are generating anything about this subject, these are the errors to avoid.

Commonly believed Colossus is permanently made of organic steel.

Actually The steel form is a transformation he enters and leaves at will. In his normal human form he is an ordinary man and fully vulnerable, which is why the stories are careful about when he is caught untransformed.

Giant-Size X-Men

Commonly believed Colossus is as strong as the Hulk.

Actually He is written in the class below — able to trade with Juggernaut or the Thing briefly, not to match Hulk-tier strength. His durability is what keeps him in those fights, not his output.
