Kirby (SSBU)/Up smash

Overview
A bicycle kick. For the entire duration of the hitboxes (frames 12-17), Kirby's foot is intangible. It has the fastest interruptibility of Kirby's smash attacks (27 frames of ending lag) and consists of a clean hit that lasts for its first three frames, a mid hit for two frames and a late hit on the last active frame. The mid hit has larger hitboxes than the rest of the attack, but the clean hit is fairly powerful, having good knockback overall. The attack has three hitboxes, including a farther sourspot that deals less damage. Good anti-air due to its vertical range and the foot intangibility.
