Here's some resources that aren't PM-specific, but they may help out in developing your OCs.
I will try to limit anything that's for other fandoms. :)))
Hallo there! I'm Lebkuchen or Utsusemi (whichever one suits you best). I'm a multifandom little cat that is always creating and brainstorming. Project Moon is dear to me, so dear that I now have 76 OCs either in that universe or relatively adjacent! Please DO NOT tell me about your OCs because they might end up being yoinked by project moon! (I swear they're wiretapping me.)
