PK Freeze is a PSI attack appearing in every installment of the MOTHER / EarthBound series. It appears as Lucas's neutral special move in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U, as well as being one of Ness's custom variants for his neutral special move PK Flash in Super Smash Bros. for Nintendo 3DS / Wii U. When used, Lucas sends a snowflake into the air that travels in an arc in front of himself automatically unless influenced and for as long as the special attack button is held, and freezes opponents rather than exploding. Opponents stay frozen longer the longer the move is charged. The move automatically strikes once it hits the ground or once it reaches the altitude at which Lucas started the move, but if it lands at a point above where it was originally started the attack disappears without damaging. After using the move in midair, Lucas is left helpless.
