I've seen a lot of cases of female characters who aren’t that thicc or stacked in their official designs, but the fandom just collectively decides is really busty (Cynthia from Pokemon, Marina from Splatoon, Makima from Chainsaw Man ect.) It's not a bad thing of course...in fact it could be a good thing, even though she's not officially got big boobs people decide that's what she deserves! M-maybe (or they're genuinely just gaslighting themselves). I do think it's interesting how it doesn't just apply to every character in something. Like it seems to be agreed upon in porn for the most part that all of the female Splatoon idols have big boobs except for Pearl and Shiver (albeit not as much as Pearl), despite not being any less top heavy than their fellow idols. How does THAT happen?

So, have any examples of female characters you headcanon as having massive boobs?

I think all robot characters just have detachable boobs. Like, with sensors in them and stuff. So they can put on the boobs and feel them like they were real, and those boobs could in theory be as massive or small as they desired.

Except v1/v2. Their pecs can prooobably round out from all the blood, rendering them... sort of titty like. Probably.
