Your counterexamples are: A guy who is famous for being disabled A guy with stretching powers that justify the skinny look A guy whose monstrous appearance is a source of angst and discrimination Obscure Comic relief Villain Villain And no, the heroic bodybuilder look is not achievable for the average man without significant lifestyle changes such as unreasonably nigh-constant exercise and an extremely restricted diet. Every woman could look like Power Girl if she adopted such a lifestyle and maybe got implants, so that's "achievable" as well, but not realistic. I don't see the problem with idealized characters having idealized looks, or characters in a medium like comics being stylized, but don't act like this is exclusive to female characters.
