I'd say that the name 'Peter' but this isn't entirely true for comic Colossus (Piotr Rasputin).
They all are male and they have red in their costumes.
They all enjoy peanut butter on their hamburger.
They are all white guys?
Hey man, Pain Ass could be any ethnicity under that mask.
Kitty pride has been into al of them
They all have red color on their uniforms
They are red clothes..
They wear masks or somehow cover their face
They are all white people
Colossus doesnt have a mask. Thats just his face
What do you think?
