mcs with mary sue vibes?

there are so many mcs with mary sue vibes but no one bothers to mention them and i want to hear from yall

imo Kalia from "The Baby Isn't Yours" lowk gives me mary sue vibes bc out of nowhere shes related to the king of fairies and the only "hints" we got was some tree children sensing that she was "special" and like no scenes from her past that also shows HOW shes special
