SCROUNGED (when was the last time you saw that word?)"One with a take-out order?"
HITMAN"History or mystery"
I love puns, so this was fun for me. I particularly liked MASHHYSTERIA and ATOUCHOFCLASH.
Wasn't wild about "Perfection symbol" for TEN since I don't see the numer as a symbol. A better clue might be "Perfection, at times."
Nor did "Unlikely protagonist" for NONHERO sit right with me. I'm not sure non-hero is a ligit word, but if it were, it would not be defined that way. A protagonist is a leading character or hero(ine), so a non-hero could not possibly be a hero (protagonist.) Unlikely
suggests it is possible for a non-hero to be a hero. A better clue might be "A minor character" or "Not the protagonist."
