I was trying to remember that list I read cause it had some great images to go with it to show what I'm talking about. It's actually quite interesting to me that comic writers came up with an "explanation" for the standard Most Common Superpower physique--namely that they're fake.
I know one of them they mentioned was Jubilee, who apparently got her's after she lost her superpowers (somehow? I don't read X-men). It's not like this was subtle either, it was made quite obvious too. I looked it up and, yeah, it's some straight up BE there. She goes from COMPLETELY flat-chested to, a couple months later, having fairly large breasts. I think she outright says so even.
To give you an example (because pics or it didn't happen), Jubiliee looked like this for 20 years:

Now she looks like this:

Fans have apparently taken to calling her "Boobilee" now.
Edit: oh yeah and she's a vampire now. Why? Because comic books, that's why.
