My friends said that one of his Pokemon has a ability that can hit Pokemon through protect cause we are building teams to battle with and we each give one hint to each other Pokemon and that's the hint
Unseen Fist is an Ability exclusive to the two Urshifu forms, and it is the only Ability that can bypass Protect. If you also want a list of moves that deal damage through Protect, check this Bulbapedia page.
