Story of a thousand stars

lets just say i got into gravity falls again and couldn't find any mythical/hybrid/etc reader so um here i am with some s/o scenarios ig? headcanons definitely and just maybe one-shots but not likely lol
reader is gn and not human at all (although yk, they kinda look like human cause its a but easier for me and stuff)
some may have, like, an animal/mythical creature/god/etc form
