If Terry is over 100% damage, or has less than 30% of his health in Stamina mode, and the player inputs either ↓ ↘ → ↓ ↘ → + Attack/Special or ↓ → ↓ → + Attack/Special, Terry will rush forward with a shout of "Are you okay?". If the move connects with an opponent, Terry will fire a large explosion directly in front of him, shouting "Buster Wolf!" as he does so. A successful use will cause the screen to have a blue overlay. Buster Wolf also has 8% damage-based armor from Frames 1-15, allowing Terry to shrug off weak attacks.
If the opponent is lying on the ground when hit by the first lunge, they'll be knocked away weakly for minimal damage and Terry will not follow through with the explosive finish. This also occurs if the opponent is too high above Terry. This is due to the command grab hitbox actually being smaller than the attacking hitbox, which knocks them out of range. This can be unsafe on hit.
Terry will also not follow through if the initial punch is shielded. This is because while the move is treated as a command grab, it cannot grab opponents that are shielding. It is one of the few command grabs with this trait (alongside Fishing Rod and Grappling Hook). This is due to it having a normal hitbox before the grab starts, likely as a balancing factor. Due to it being a grab upon connecting with an opponent however, it can notably affect Incineroar, Joker and Banjo & Kazooie while they are performing Revenge, Rebel's Guard and Wonderwing respectively.
Like Power Geyser, this move cannot be performed in the air.
Like his normal specials such as Power Wave, Terry can cancel the endlag of his normals into Super Special Moves as well. Buster Wolf does happen to have confirms, namely out of forward tilt pre-tumble. This can serve as a very early kill confirm should it connect at the edge. Outside of this however, it is generally unreliable.
Additionally, the first hit of Buster Wolf itself can be cancelled into Terry's Final Smash, Triple Wolf.

Buster Wolf was a move introduced in Garou: Mark of the Wolves, and has since become one of Terry's signature moves, seen in practically every game he's included in. The command used to perform the move in Ultimate mirrors the command for it in most games.
