Well, the wiki itself says that Superhumans gain their "idealized body", which takes into consideration the person's mental state and their own securities and insecurities.
Still, we've never really gotten an MC level of body uplift on any of the women, which is strange when you take into account the law of averages.
Like, I've only seen men transform like that, while the women barely ever change, save for a few - but it's hard to count some of them, because we have no idea what they looked like pre-Superhuman.
Alice didn't change one iota, and neither did Liz or Amber besides an outfit change and some more superficial ones. Like, are their bodies *really* their idealized versions?
