Character archetypes/existing but not implemented characters

So this ones gonna be about characters I'd like to see, or character archetypes that'd be interesting to see in future characters. And remember they're just Ideas so chill yourself if you're one of those people who see "want to see in league" and immediately want to scream NO, o God please No,Nooooo like that one meme (you probably knew the one I mean.)

Anyway starting off -an observer/watcher style character: if you're a marvel fan the concept of The watcher makes sense to you, a character who exists in the universe but is for as long as possible not associated with the actions happening in their world, merely spectating them who could reveal some interesting things -The ruined king: o boy, that's right the guy who caused the shadow isles creation would be pretty badass -a human whose aware of Yordles: not just because their magical like Swain, but one who actually just is immune to their glamour and interacts with them while being their own character

Feel free to leave ideas below, maybe I'll think of more but for now that's all I've got
