Sonic Wave (ソニックウェーブ, Sonikku Uēbu) was Super Sonic's side special move in Super Smash Flash 2. Sonic curls into a ball and fires off a powerful energy blast directly in front of him. The attack deals extreme knockback at higher damage percentages and can pass through enemies. It was completely replaced by the Spin Dash in v0.7 of the demo.
