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, it 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. When it hits, it creates a pillar of fire that blocks the enemy from passing through it. It can also be performed in the air, which causes the bolt to move in a diagonal fashion, similar to Sheik's needles.
Lucas' version of this attack works almost the same as Ness's version, except Lucas' PK Fire always travels in a horizontal fashion, and the fiery explosion seems to be far greater.
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.
