my fav badges are the kind where it looks like the character is interacting w/ the punch hole (or whatever your hanging meathod it), like they're grabbing it or swinging from it or w/e

I like Lioness' idea. And then something that matches the theme of the convention that year is good.

idk, recall def wanting something with tucker coosplaying guts in his black dragon armor(i know this is not a theme but UGh it would be dope)

but as a real theme maybe something like kaiju versions of OCs people have would be dope
