Character themes? (Patreon)

I have a few ideas for themes, but im curious to hear what themes you guys think would be good. For example: say the theme is dad, you guys then would suggest character who are fathers. Another one we did was DBZ. Thoose are themes for voting. Now, what kinda themes do yall wanna see?🤔

(I don't mean environment themes, or concepts. What I'm talking about it purely for choosing characters. So we don't get the same characters over and over)

(Hopefully this makes sense)
