Kirby (SSBU)/Up smash

Hitbox visualization showing Kirby's up smash.

Overview[edit]

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 and launches at a more favourable angle, but the clean hit is the stronger one and it's fairly powerful, having good knockback overall. The attack has three hitboxes, with the tip of Kirby's foot being a sourspot, and it deals even less damage on the move's last active frame. Good anti-air due to its vertical range and the foot intangibility. Its late hit has very low knockback however, having no KO potential.

Update History[edit]

3.0.0

• Its clean hit has a longer duration, with the late hit having a shorter duration instead (frame 12 (strong)/13-14 (mid)/15-17 (late) → 12-14/15-16/17).

6.0.0

• Its clean sourspot deals more knockback (30 base/99 scaling → 36/104), with the knockback values matching the sweetspots.
