🧣 Ooh, interesting! I hadn’t really thought about these questions before, since we kinda just all love tf a lot, but I have a few ideas!
For transforming others, Clover comes to mind, thanks in part to recency bias (she’s new), but also just because her whole vibe is “little fairy who transforms people”! In fact, she’s already made Key grow a pair of moth wings once, if you’d believe it… Anyways, other contenders for this title are any headmates featured in stories of mine who are depicted transforming others (Gale, Beryl) and Soda (who doesn’t exactly transform people as her “job”, but has gone and created an entire business that provides transformations for others).
As for being transformed… Well, we all love this a lot, so it’s hard to say… Maybe Lock, though? Lock is kinda like a secondary skin of Key (gray hair and brown hoodie instead of Key’s brown hair and gray hoodie), but is also way subbier. So yeah, it’s probably her who likes being transformed the most, but I’d be remiss to not also mention Cozy and her love of relaxation and comfort. Depending on the form, her desire to be modified might exceed Lock’s!
This was super fun to think about, thanks so much!
