From the list, These ones are my fav:

Superhero/Supervillan (Gritty/Dark)
Fantasy World building (Original World that we create with lore ((A Deep one)))
Harry Potter OCs
Cross Realm characters (From different stories Movies/videogames)
Skyrim OCs

but if you really want to do something specific, feel free to do so ~
