Apologies for not being helpful in narrowing it down! I am pretty open to any given goddess, since the way I see it if it's one that's very "fitting" for Leela, like a war goddess, then well that makes sense. If it's one that's not fitting for her, then that could be fun to play off of at times and likely it was the only Familia she could get into or it was simply the first one to grab her up. So for me at least, it really is pretty open! That said, if you really need one specific vote then I suppose I'll just say Athena, since that's still my "top pick".

Enjoy your nap and hope you feel better! Being sick sucks.

On the note of pictures, I'll dig around and see what if I can find anything suitable for Leela. At the very least face-wise, since the entire thing is pretty specific and I doubt I'd find an exact match unless I drew it myself or got super super lucky.
