Kirby (SSBU)/Up tilt
A scorpion kick from back to front. One of the fastest up tilts in the game, coming out on frame 4, lasting until frame 10 and having almost no ending lag (10 frames). For the entire duration of the hitboxes, Kirby's foot is intangible. Has rather poor vertical range, but the hitboxes are slighly disjointed. It deals low damage, but its very low ending lag and vertical angle make it one of Kirby's best combo starters. Can set up into another up tilt, up air, or even Inhale.
