It’s hard to believe that a hero that's usually shown not even have normal flesh would be known for his sex appeal, but Colossus definitely is. While he’s been a longstanding member of the X-Men, Colossus has always been known for his massive frame and surprisingly skimpy costume. Unlike other “sexy” heroes known for their bad boy qualities, people are drawn to Colossus because he’s generally really sweet and caring, not only with his affection towards Kitty Pryde but also with his sister Illyana. Even with his sweet personality, comic book fans will probably never forget his “centerfolds” from those old swimsuit issues.
Pretty much every superhero in comic books has a superpower that isn’t really mentioned. Sure, some billionaire genius could, theoretically, learn how to build powerful metal suit and fight crime similar to Iron Man. However, that person still won’t have all the superpowers of Tony Stark. You see, Tony Stark is a ridiculously attractive man. Wonder Woman, in addition to being a badass warrior that could pretty much dominate any foe, is also incredibly beautiful. Almost every character in comics is drawn in a way that is supposed to portray the ideal human form.
