Terry tilts his cap backward before leaping into the air, hitting twice with his knee while taking the opponent with him, and performs a downward-angled diving punch toward the ground. While performing the move, Terry says either "Power Dunk!" or "Beat up!" After performing the move, Terry then tilts his cap back to its original position. The move sends diagonally outward at a harsh angle. The move has low enough ending lag in the air for Terry to safely recover afterward. Like all of Terry's special moves, Power Dunk has two variations depending on how long the button is held, although in this case it only affects the height of Terry's initial hop and the pause before he punches downward, with the move's damage and knockback unaltered. The light version performs a shorter hop and a faster punch, while the heavy version allows Terry to jump past the bottom platforms of Battlefield, and slightly delays the punch.
Input Power Dunk
If the player performs the move's original input (→↓↘+attack/special or the "Shoryuken command" as mentioned by Masahiro Sakurai), Terry will perform a stronger version of the move. The command-input version causes the initial shockwave from Terry's flaming fist to turn blue, alongside the end of his fist's trail. The strong version of the punch where the attack button is held will also meteor smash a few frames after Terry is falling, with the sweetspot being the center of Terry's fist, before becoming a stronger version of the initial hitbox. Additionally, the move grants Terry intangibility from frames 6 to 12, allowing it to work as a combo breaker option.
Terry can perform a Power Dunk out of some standard attacks, as part of his special-canceling mechanic. By pressing the down special input or command input after connecting with one of certain standard attacks, Terry will cancel the ending lag of the attack and perform a Power Dunk. This can be used for combos. One of the most commonly used combos involves special-canceling Terry's neutral attack before its third hit into Power Dunk, although this can be SDI'd out of. Neutral aerial is one of the most common alternatives to confirming Power Dunk given this fact.
Power Dunk itself can be cancelled into Terry's Final Smash, Triple Wolf during the rising hits.
Power Dunk is a move in Terry's repertoire that first appeared in Fatal Fury 3, that was introduced as a reference to his love of basketball and slam dunks, Terry also tilts his cap backward used as reference to his Climax Super Special Move in The King of Fighters XIV, Star Dunk Volcano.
