Sonic (SSB4)/Forward aerial
A corkscrew battering ram, similar to Pikachu's forward aerial. It has fast start up, hitting on frame 5, hits multiple times and its last hit has high knockback scaling, which makes it useful for edgeguarding. It can also combo into itself in certain instances thanks to Sonic's fast air speed. Originates from Sonic the Fighters. However, it has high ending lag (31 frames) and landing lag (26 frames).
