Super Sonic Boost

Super Sonic Boost was 's up special move in Super Smash Flash 2.

Overview
When performed, Super Sonic covers himself in yellow energy and rockets at high speeds in the direction pressed, during which time the player can freely move left to right. and any foe caught in the energy will be dealt multiple hits of 1% damage each, as well as weak knockback. The move travels a very far distance and does not leave Super Sonic helpless, making for a strong recovery move despite Super Sonic's infinite midair jumps.

Origin
The Super Sonic Boost is a Chaos Power used by both Super Sonic and Super Shadow in the  franchise that was first used by Super Sonic against Biolizard in Sonic Adventure 2, but it was not actually given a name until Sonic Unleashed. When performed, the user surrounds himself in a powerful fiery aura of chaos energy (where the known color is either blue or yellow) and flies into the target at incredible speed, resulting in a quite devastating impact that can stun creatures as large as Perfect Dark Gaia. As seen in Sonic's case, the Super Sonic Boost can be performed for unlimited time (or for as long his can maintain his super transformation) as Sonic's Boost Gauge is given unlimited amounts of energy from his super transformation.
