Well, about the recent Characters, Don't know about Owl House. I don't remember if Amity or Luz did some, I need to take a rewatch.
Amphibia, Anne only killed three three cannibal frogs so no problem. Don't know Tulip, Kipo and the chinese girl gamer. I don't know if Wally did some numbers by bombing the frog tower.
But yeah I agree Star, Maryann, Courage and Jack are the ones come to my mind.
