It's possible you're thinking of a different move. Honchkrow can learn several strong moves, including:
* Brave Bird: A powerful Flying-type move that deals heavy damage but also has recoil damage to the user.
* Heat Wave: A Fire-type move that can hit multiple opponents.
* Night Slash: A Dark-type move with high critical hit rate.
* Superpower: A Fighting-type move with high power, but it lowers the user's Attack and Defense after use.
To learn these moves, you'll need to level up your Honchkrow, teach it TMs, or breed it with a Pokémon that knows the move.
If you're still unsure about the specific move you're looking for, please provide more context, such as the game you're playing or the move's description.
