you can really do anything with them as long as you don't claim to own/make them. You can do stuff like make art, songs, models, fanfics, even weird stuff. But there's one thing that I don't want done with my characters that being vore and I'm in no way trying to shame someone's kink or anything of that sort, people are weird like the rest of us and that's great, but that's one of the few things I don't want done with my characters as it makes me very uncomfortable. Please understand, have a great day and a happy pride month. :)

(lmao never thought I would need to make this but whatever.)
