>>48054875It exists solely to be Bruxish's signature move that goes with its whole deal of being a Psychic type with Strong Jaw and all the bite moves. Sure other mons can get it, but only through late/end game shit like Move Tutors and TR's. There's lots of moves like that, where while other Pokemon can technically learn it, it's blatantly meant to be "that" Pokemons trademark.
