Most Common Superpower/Playing With

Basic Trope: A female superhero or superpowered fantasy character has very large breasts, often to an unrealistic degree.
 * Straight: Amazing Girl is a DD-cup.
 * Exaggerated: They don't make bras big enough for Amazing Girl.
 * Justified: Amazing Girl's powers have a mildly transformative effect on her physique, increasing her bust size in the process.
 * Alternatively: Amazing Girl isn't human. Given that she even has them, they're as likely to be that size as any.
 * Alternatively: Hey the majority (or entirety) of the Male character cast has "seemingly perfect bodies" so why should the ladies be exempt from that?
 * Amazing Girl is a shapeshifter and gives herself large breasts for the hell of it.
 * Amazing Girl isn't really that large, but has false breasts as part of her costume to help conceal her secret identity.
 * Inverted: Amazing Girl is an AA-cup.
 * Alternatively: Amazing Guy is a DD-cup.
 * Amazing Guy is 12 inches long.
 * Everyone except the superheroes has large breasts.
 * Subverted: Amazing Girl is discussed as if she has overly large breasts, but they are revealed to be smaller than expected.
 * Doubly Subverted: However, she is later hit with powers that increase her bust size.
 * Parodied: Amazing Girl's breasts are so large she needs to carry something in front of her to support them.
 * Alternatively: Amazing Girl uses her figure to gain employment in the sex industry whilst not fighting crime. See Stripperella.
 * Or: Amazing Girl actually makes use of her giant bazookas in a fight. Nobody ever takes Baron Wasteland seriously again after that.
 * Deconstructed: Amazing Girl's figure has led to her becoming a figure of derision amongst the superhero community, meaning that she is not taken seriously as a woman or as a crime fighter. It is assumed that because of her breast size she is an airheaded 'slut' and she is often the victim of sexual harassment from other superheroes, whilst simultaneously the subject of jealous gossip.
 * Alternatively, Amazing Girl's bust gets in the way when she tries to fight crime, and she is plagued by chronic backaches.
 * Reconstructed: However, Amazing Girl is a confident and strong person regardless, is proud of her body and manages to overcome these issues to be a hero. Besides, her boyfriend likes them.
 * Alternatively, Amazing Girl's breasts hinder her when she fights crime, but male criminals are too Distracted By the Sexy to escape successfully anyway.
 * Alternatively (again), Amazing girl's superpower is being large-breasted, as well as the Required Secondary Powers that go along with it (super strength, impeccable balance)
 * Averted: Amazing Girl is depicted as having average, realistically sized breasts.
 * Enforced: "The people reading our comics are mostly men. Men like women with large breasts. Ergo, give Amazing Girl large breasts and men will like her!"
 * Lampshaded: "It still sometimes amazes me that I can still fight crime with these!"
 * Invoked: "Female superheroes need large breasts. It's essentially a job requirement."
 * Alternatively: They're fake. Amazing Girl got implants before she started fighting crime so she'd fit in (or pads her bra while she's in costume.)
 * Amazing Girl intentionally fakes / changes her bust size and exploits it in order to help protect her Secret Identity; not only is her civilian persona a lot less buxom than her superheroic identity, but people who are focusing on her breasts aren't focusing on her face.
 * Amazing Girl's Secret Identity looks fairly normal; when she says the magic words her clothes turn into her costume, she becomes more muscular and her breasts grow significantly larger. Of course, the Transformation Sequence never fails to highlight this.
 * Defied: "I don't need unrealistically large breasts to fight crime!"
 * Discussed: "Seriously, outside of a comic book no one has breasts like hers!"
 * "Superheros that like small breasts must have trouble finding girlfriends."
 * Conversed: "Amazing Girl's breast size is ludicrously unrealistic!"
