Ground Shaker

Ground Shaker is a move used by Knuckles the Echidna in Sonic the Hedgehog (2006). When using this move, Knuckles dives into the ground to create a ripple to attack foes.

Description
When performing Ground Shaker, Knuckles jumps into the air where he then dives straight downward with fists first while spinning his entire body around himself rapidly and giving off a flaming red aura. Knuckles then impacts the ground with his fists with such force that he creates a disruptive ripple along the surface to damage the surroundings, before he jumps back on his feet.

When used in gameplay, Ground Shaker can not only damage enemies, but also paralyze them, leaving them immobile. To perform Ground Shaker in gameplay, the player must press / during a jump. Once the attack has begun, however, it cannot be interrupted before after Knuckles has hit a surface.

Trivia

 * The Ground Shaker resembles the Drill Claw used by Knuckles in Sonic Adventure 2 and Sonic Adventure 2: Battle. The main differences are that the Ground Shaker damages and paralyzes enemies, cannot penetrate the ground, and cannot be interrupted.
