Kirby (SSBU)/Up smash

Hitbox visualization showing Kirby's up smash.

Overview

A bicycle kick that hits all around Kirby. At frame 12, it is a situational out-of-shield option. However, it has the fastest interruptibility of his smash attacks, with 27 frames of ending lag. Kirby's foot is also intangible for the entire hitbox duration, giving the move a disjoint and anti-air properties. The tip hitbox on Kirby's foot is a sourspot, dealing 1% less damage.

The clean hit comprises the entire front half of the kick, and is a relatively strong up smash when sweetspotted. The mid hit has slightly larger hitboxes, with a nearly straight upward angle, but is overall weaker and punishable on hit at low percents. The late hit lasts for a single frame, but despite its good damage, it has extremely low knockback with a diagonal launch angle; it is punishable on hit until high percents and cannot KO at realistic percents.
