Upon activation, Terry will shout "Overheat!" and release a Triple Geyser, consisting of three consecutive Power Geysers. If an opponent is hit by one of these geysers, gameplay will transition into a cutscene, where Terry will perform a Power Dunk, shouting "Slam!", before charging his fist up, declaring "Here's the big one!" and performing a cinematic Buster Wolf while shouting “BUSTER WOLF!!”. If multiple opponents are hit by the Triple Geyser, only the first one will be subject to the full combo.
The Triple Geyser is capable of dealing a lot of damage to bystanders; the cinematic finisher can KO Mario at around 60% from the center of an Ω form stage, while the geysers themselves can KO at around 130% under the same conditions, though the latter is only relevant if the move strikes multiple opponents. Due to the move's massive range and ability to combo from a wide variety of Terry’s moves, it is an effective Final Smash against single opponents.
The move combines Power Dunk, a special move of Terry's, with Triple Geyser and Buster Wolf, two of Terry's Super Special Moves from the Fatal Fury series. Triple Geyser, an improved version of the Power Geyser, was first introduced in Fatal Fury 3, where it was a Hidden Super Desperation Move that required a hidden button combo pre-match to use (as Power Geyser was a Desperation Move). Buster Wolf was introduced in Garou: Mark of the Wolves. The incorporation of Power Dunk in the Final Smash could be a reference to Real Bout Fatal Fury Special, where it is used as the first part of Terry's secret Desperation Move, High-Angle Geyser, or The King of Fighters XIV, where it is turned into a super move in the form of Star Dunk Volcano.
Terry's cries of "Here's the big one!" and "BUSTER WOLF!!" in this Final Smash are heavily inspired by his voice clips for EX Buster Wolf from The King of Fighters XIV.
