PK Fire
PK Fire (called PSI Fire in the English version of Earthbound) is a special move that can be performed by both Ness and Lucas in their respective Smash games. It is a projectile attack performed with Forward-B. When performed on the ground, a bolt travels in a straight line until it hits an enemy or destructible portion of the stage. If it does not hit either of the aforementioned objects within a few feet, then it disappears.
Lucas' version of this attack shares differences from Ness's version. Lucas' PK Fire always travels horizontally. When the hits an opponent, it hits once, and deals fair knockback to the enemy. In all games of the Smash series, Ness's PK Fire explodes into a pillar of fire that hits an enemy multiple times, which can lead to potential combos while the enemy is stunned. Ness can also fire his PK Fire diagonally downwards if he uses this attack in the air.
In Earthbound, the attack is actually not learned by Ness (something Paula's Trophy in Melee explains). It is described as a wave of fire shot from the fingers and is capable of damaging rows of enemies.
