Literally two different characters in my inbox, from two different artists, are named Yvette!

Also haaaaaaaaaaawt

Ooooh!

I remember seeing pics of her a while back. She looks like someone I'd probably bump into at a game store and hang out with watching cheesy movies.

Yeah, she's a bit of a nerd :p
Glad you like her!

I do. And I gave the story a read too. Gotta love when a character 'expands' their horizons. I would love to see and read more about her.

And I missed us talking about her and the Changelings too.

Comparing this to the 2020 reference sheet, I wonder if Yvette simply has a private kink for becoming massive, if not bodacious, or her personality is just slightly different in the story on FIMFiction.

In essence, the Fimfic story is more or less a precursor to how she is in the ref sheet. In the fic it was a private kink, yeah, but some time after it became more and more public-ish. So yeah, her personality between the two is slightly different, but only due to the passage of time in her universe.
That all being said, there's still scraps of lore for her here and there that I haven't really fully fleshed out yet (no pun intended). Some people have suggested certain kinds of things that have really pressed my buttons in the right way that I still need to work out how to incorporate into her lore.

I would have liked if there were more illustrations of her when she is plumped up.
