There were some slight changes from Ditko's armor to the one featured here, mostly with the face mask, but since those changes were made, that basic design has been fairly consistent. Now, Iron Man's armor has obviously been altered in other ways as technology has changed, but the basic yellow and gold design has been used almost exclusively since then. No matter how fancy the armor gets otherwise, the yellow and gold set-up is a catchy design.
Vartox belongs on this list, not because of his sexy nature, but because of how he was created to be sexy and ultimately failed. Unfortunately, over the years, the sexy nature of his design was lost, and the ridiculous costume and silly look defined the character. His look is also lampooned a bit in his appearance in “Power Girl.” There, he tries to woo Power Girl into helping him repopulate his home world. He dons a black leather speedo and see-thru robe, trying to show how sexy he is. Unlike others on this list who are actual sex symbols, Vartox is here because he was created to be a sex symbol, but fans never really bought into it.
The red and blue webbed costume that Ditko came out was one of the most unusual superhero costumes ever designed, but despite it not really looking all that much like a spider, it really did fit the character well. Although artists sometimes differed on whether to give him webbing under the arms and artists like Todd McFarlane have certainly differed with how big the eyes on his mask are, the basic costume design has remained the same for over 50 years.
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.
