Kirby (SSBU)/Down smash

Hitbox visualization showing Kirby's down smash.

Overview

A spinning split kick. It has the fastest startup of Kirby's smash attacks (frame 10), but the highest amount of ending lag (FAF 54, 31 frames of ending lag). It is a semi-spike, with Kirby's feet being intangible, starting from frame 5 and lasting until the clean hit ceases at frame 14. The clean hit deals 14% and has above average power for a semi-spike, while the late hit deals 10%. Due to its long active duration, it's Kirby's best option for 2-framing.
