Upon releasing the button, or after approximately 3 seconds have passed, Knuckles will leap out of the ground with a spinning rising uppercut, dealing damage to anyone above him when he re-emerges. In the air, Knuckles will perform Drill Claw instead. Knuckles will pause for a moment, and then begin to head directly towards the ground while spinning.

In the air, Knuckles will instead begin to glide forward. He can remain gliding for approximately 2 seconds, and is capable of changing direction while he does so. If Knuckles comes into contact with a wall whilst gliding, he will stick to it for a moment, and can climb up or down the wall while he is attached to it.
Up special		Spring Jump	N/A (jump), 4% (spring)	Bounces off of a Spring. When used on the ground, it remains in place for a few seconds, allowing Knuckles and any other character to keep bouncing off of it until it vanishes.

Down special		Spin Dash	1.5%-2.4% (loop), 4% (last)	Begins charging up a Spin Dash. The player must mash the button after inputting down special to continue charging.
