PK Fire is a PSI attack, introduced in EarthBound Beginnings. It has a variety of effects between games, but the most common effect is hitting multiple enemies for fire-based damage. PK Fire is learned by Ana in EarthBound Beginnings, Paula in EarthBound, and Kumatora in Mother 3.


PK Fire is a fire-based PSI attack that the user summons from their fingers. Damage output depends on the enemy, as enemies associated with ice are more vulnerable to the attack; additionally, characters with the H2o Pendant (in EarthBound Beginnings) or the Flame Pendant (in EarthBound) equipped will be more resistant to it.

PK Fire of all tiers is a multi-target PSI attack. In EarthBound Beginnings and Mother 3, PK Fire targets all opponents on screen. In EarthBound, the targeting is slightly different; instead, it only targets all enemies in a selected row. In EarthBound Beginnings, only PK Fire Ω one-hit KOs all opponents on screen, including ones that are unaffected by PK Beam γ. PK Fire can also cause secondary effects: In EarthBound and Mother 3 it has the possibility of decreasing one of the targets' PSI Shield strength by 1, and in Mother 3 only it can set the target on fire, causing them to gradually take damage every turn.

Lloyd's explosives in EarthBound Beginnings all share the effects of each PK Fire tier: Bottle Rockets are α, Bombs are β, Flamethrowers (the only reusable one) are γ, and Super Bombs are Ω, although Super Bombs inflict recoil damage on Lloyd unlike PK Fire Ω.

In EarthBound Beginnings, the explosion caused when certain enemies are defeated are also equal to PK Fire.

  • PK Fire's damage is affected by the enemy's resistance to fire according to the formula Actual Damage = (Base Damage) x (Enemy Weakness) / 100. If Kumatora uses PK Fire α on an Osohe Cape, which has a fire weakness of 120, it will do between 72 and 96 points of damage.
  • Mother 3 introduced a new secondary effect for PK Fire, adding a chance of setting an enemy on fire, and take a small amount of damage for several turns. Like most status ailments in Mother 3, PK Fire has a base chance to engulf the enemy in flames, modified by an enemy's inherent weakness to flames, according to the formula Actual Success Rate = (Base Success Rate) x (Enemy Weakness) / 100. PK Fire's base chance to engulf in flames is 8. If used on an Osohe Cape, which has a Flammability of 100, the enemy will be engulfed in flames 8% of the time.

In the Super Smash Bros. series

PK Fire appears in every Super Smash Bros. game. It was Ness's neutral special in Super Smash Bros., before being moved to his side special in Super Smash Bros. Melee onwards when PK Flash took its place. When Lucas was introduced in Super Smash Bros. Brawl he too also has PK Fire as his side special. It is implied that Paula and Kumatora taught Ness and Lucas respectively how to use PK Fire, as neither could learn PK Fire in the EarthBound series.


Ness using PK Fire.

Ness' variant of PK Fire shoots a lightning bolt at a slight downward angle. When it hits a player it ignites into a pillar of fire that continuously burns an opponent for a short period of time.


Lucas using PK Fire.

Lucas' variant of PK Fire shoots a lightning bolt goes directly ahead of him, and Lucas is slightly pushed back during the firing animation. Instead of starting a pillar of fire, it ignites in a single burst with low knockback.


In Super Smash Bros. for Nintendo 3DS and Wii U, Ness has two extra variants of PK Fire as custom special attacks:

  • PK Bonfire: The lightning bolt doesn't travel as far, but the pillar of fire is larger and lasts longer.
  • PK Fire burst: Ignites into a single burst, functioning identically to Lucas's variant.

Due to Lucas's status as a downloadable character, he does not have custom variants of PK Fire.
