Nova Burst
Rather than a starspin, Nova, Smash's Luma buddy, Gives him a burst of power and speed. This helps him get running starts, extra boosts over obsticals, and smash through enemies. Nova, being the little resilient Luma he is, can help Smash preform these moves in rapid succession, but uses a starbit in order to do so. Smash himself can't help himself to snack on a few starbits himself.
