* A rock in a video game: What game are you asking about? Different games have different moves.
* A rock musician: Rock music is a genre, not a person. You might be thinking of a specific musician's signature move.
* A rock type in Pokémon: Rock type Pokémon have specific moves, but there's no one "special move" for all of them.
Let me know what you mean by "rock" and I'll be happy to help!
