Overview

PK Beam does not belong to a specific element but instead is a psychic beam that is fired at the target. It is the most powerful single-target PSI attack in the game, with PK Beam γ being a one-hit KO attack that instantly KOs a target reguardless of the amount of HP they have. The first three tiers of PK Beam are a single-target attack, and Ω attacks all opponents on screen. PK Beam Ω is the strongest non OHKO attack in the game dealing 100-210 damage.

Because PK Beam does not belong to an element, there is no pendant that can protect the player from it, not even theSea Pendant. However theFranklin Badge will reflect PK Beam γ back at the enemy, additionally mechanical enemies are resistant to PK Beam and are also immune to γ altogether.

Lloyd's Laser Beam and Plasma Beam are funcionally the equivalent to PK Beam α and β respectively.

In later games

PK Beam is the only offensive PSI attack that does not return inEarthBound andMother 3, however it is likely to have been replaced withNess andLucas's respective favorite thingsPSI Rockin andPK Love, as they are also PSI based offensive PSI attacks that do not belong to an element, similar to PK Beam. The only difference is that all tiers are multi-target whereas only PK Beam Ω targets all opponents. Additionally PK Beam γ's one-hit KO property is present inPK Flash.

In theSuper Smash Bros. series

TheStarmanassist trophy is able to use PK Beam inSuper Smash Bros. for Nintendo 3DS and Wii U andSuper Smash Bros. Ultimate. When summoned it attacks opponents with either PK Beam γ or Ω, in these games γ is single-target while Ω sends a barrage of beams. Additionally the Starman enemy in theSmash Run mode exclusive to Super Smash Bros. for Nintendo 3DS also uses PK Beam. In this mode PK Beam can be reflected back at the Starman for a one-hit KO referencing PK Beam γ being a one-hit KO, as well as Starmen being vulnerable to it.
