Force Palm

Force Palm is Lucario's Side Special Move in Super Smash Bros. Brawl. 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, which is even larger after Lucario has taken damage. Force Palm bears some similarities to Lucario's Forward Smash, except that it exhibits more range and less knockback. If Force Palm is used when standing within grabbing range of an opponent, it changes to a grabbing attack with slightly more power. Force Palm's range also makes it a viable edge guarding move, but caution should be used if attempting to use Force Palm in the air, as Lucario cannot jump until it finishes attacking with it. Force Palm can also make a good Chain grab. Initial damage for close-range is 9%, long range is 6%.

Interestingly, Force Palm can be reflected and absorbed much like Thunder is, yet even at the closest out-of-grab range, it will never hurt the same Lucario that used it. Due to its range and connection with Lucario, it is more like a disjointed hit box; however, it is in fact a projectile, as it doesn't move with Lucario when falling or slipping on the ice. Also it is possible for the opponent to break out of a close range Force Palm before the punch is administered.

Origin
In the Pokémon games, Force Palm is a physical fighting-type attack which deals somewhat low damage, but has exactly a 30% chance of paralyzing the foe.
