Force Palm (はっけい, Force Discharge) is Lucario's side special move in Super Smash Bros. Brawl, Super Smash Bros. 4, and Super Smash Bros. Ultimate. When used, Lucario thrusts its paw in front of itself, briefly charges up aura, then unleashes it in a large area in front of its palm. The move becomes a grab at point blank range, which deals substantially more knockback.
Force Palm bears some similarities to Lucario's forward smash, except that it exhibits more range and less knockback. If Force Palm is initiated close to an opponent, it changes to a grabbing attack with more power, unless Lucario is in the air. With a high enough Aura level, the grab serves as a remarkable KO option. Force Palm's range also makes it a viable edgeguarding move, although it is generally risky to use offstage due to its high ending lag. In Brawl, Force Palm can also be used repeatedly at low percents as a chain grab, much like Lucario's up throw.
Force Palm's attack has a few unintuitive properties. The blast produced by it is technically a projectile that can be reflected and absorbed, but it does not move by itself, and so reflecting it cannot hurt the original user unless Lucario is pushed into it at the same time. By contrast, it is also a direct attack, so Subspace Emissary enemies do not resist it, and it triggers the effects of items that ignore indirect attacks (such as Metal Boxes). It is also the only command grab in Ultimate that causes Cloud to lose a portion of his Limit Gauge when grabbed out of Limit Charge, rather than gaining more charge.
Force Palm also causes light-bending graphics for a portion of its animation, where Lucario stands in a readying-stance with a single hand out and the other one placed upon its wrist, firing the blast with stationary recoil. When used as a grab, it grabs the opponent with its leading hand and places its free hand onto the other (in a quick thrusting motion) to blast them in a violent gesture.
From Smash 4 onward, the size of Force Palm's blast increases in proportion with Lucario's Aura, becoming much larger at high percents. For this, the blast's scale is multiplied by the result of the formula
In Ultimate, as an additional aesthetic effect, Force Palm's throw causes a Special Zoom if used when Lucario's Aura damage multiplier is 1.14× or higher. With Stock Aura taken into account, the minimum percentages for Lucario to trigger the effect correspond to the following:
Force Palm can be escaped via button mashing. The grab duration is the same as from a standard grab, as is the effect of mashing. Since the move takes a fixed 28 frames between grabbing the opponent and throwing them, the number of inputs required to escape is consistent with percent, although escaping it is only feasible at low percents and with quick enough mashing speed. The number of button inputs required to escape is summarised for low percents below:
Special Move customization was added in Super Smash Bros. 4. These are the known variations:
In the Pokémon games, Force Palm is a physical Fighting-type attack that was introduced in Generation IV. While not very strong at 60 base power, it has a 30% chance of paralyzing the target.
Force Palm’s depiction in Smash is similar to how it’s shown in the Pokémon anime.
Lucario can learn this move by leveling up in Generations IV, V and VIII. While Lucario can’t learn the move by leveling up in Generation VI and VII due to learning Power-Up Punch in its place, its pre-evolved form Riolu can, and therefore Lucario can retain the move as it evolves. In Sword and Shield, Lucario can learn the move at level one.
In Japanese, the term "fajin" (発勁) is the naming basis for the attack's Japanese name, being a term used in Chinese martial arts that involves use of internal energies for explosive force, being the backbone for a majority of the one-shot-power-based blows from such fighting styles. "Hakkei" is the term read in on'yomi.
