The Screwdriver (スクリュードライバー,Sukuryūdoraibā?), also spelled as the Screw Driver, is a move used by Knuckles the Echidna. When performing this move, Knuckles dives through the air while spinning around.
When performing the Screwdriver, Knuckles does a forward dash through mid-air, similar to a dive, where he keeps his fists out in front of him and horizontally spins his entire body rapidly, turning himself into a flamming drilling projectile.
The Screwdriver's first appearance was in Sonic the Hedgehog (2006), where it is referred to as the Screwdriver (スクリュードライバー,Sukuryūdoraibā?). In this game, it is one of Knuckles' standard attacks. When performing it, Knuckles leaves a fiery red trail as he dashes forward.
To perform the Screwdriver in gameplay, the player must hold down / and then release to execute it. When performing the Screwdriver near an enemy, Knuckles will home in on the enemy and attack it, similar to the Homing Attack. However, this can only be done once per attack, and if the player tries to chain it, Knuckles will perform the Ground Shaker instead. Additionally, when holding down /, Knuckles will assume a stance where he pulls his right fist back and charges his power in the form of red energy. During the charge, Knuckles is immune to all enemy attacks.
