That's exactly my point. I'm against a rename just for that fact.
The trope is supposedly going hand-in-hand with how a superpowered female somehow gains a perfect body (or already had one to start with). Jubilee is not an exception: she proves the rule, as does Kitty Pryde. Their entire purposes were to be the teen sidekick (to the same guy, even). Other examples which prove the rule are Spoiler, nearly every female member of Young Justice
, Generation X, New Mutants and Teen Titans
(until they grow up), and so on.
In fact, having studied as a commercial artist, I can tell you that comic book companies (such as Marvel) actually impose
the attitude that if you're drawing a superheroic woman that is supposed to be larger than life, then her body is supposed to support that. She's supposed to be iconic to look at. Likewise, if the girl is a teenager, you have
to make her smaller and plain in order to reflect that. This isn't just a trope, but an Enforced Trope
within the industry.
And Japanese media is no different. Most flat-chested women are either supporting characters or Staff Chicks
or Lolis. The super-powerful women (that is, the ones who get down and dirty on the front lines) are usually buxom. (Even here, this is not always the case, as Rukia and Orihime from Bleach
are inversions. Almost every woman from Fairy Tail
plays this straight as an arrow, though, as do half of the female cast from Naruto
Yeah, I think renaming this trope would be a terrible, terrible mistake that would pretty much destroy the only thing that makes it different from the other boob tropes.
