Screw Attack (move)

The Screw Attack is an upgrade from the Metroid franchise that appears in every Super Smash Bros. series title as Samus's up special move. Upon using it, Samus quickly somersaults into the air, surrounded by an electrical field that continuously damages any opponents caught in it. In Super Smash Bros. Ultimate, Screw Attack is also Dark Samus's up special move.

In Super Smash Bros. for Nintendo 3DS / Wii U, this move has two unlockable custom variations. The first is Screw Rush, which quickly sends Samus diagonally up rather than directly up and deals more damage. The second variant is Apex Screw Attack, which only deals damage at the beginning and peak of the jump.

A Screw Attack item also appears in each installment, though it functions somewhat differently from this move.
