PK

Ness and Lucas using PK Fire

PK, known as PSI in Super Smash Bros. Ultimate, is an attack type in the Super Smash Bros. series that encompasses attacks from Earthbound characters using their PSI powers.

PK attacks are boosted by PK Attack stickers in Super Smash Bros. Brawl's The Subspace Emissary and the Spirit skill or trait PSI Attack ↑ as well as certain Spirit Battle conditions in Super Smash Bros. Ultimate. PK attacks are resisted by the Support Spirit skill PSI Resist ↑ in Super Smash Bros. Ultimate.
