Kirby (SSBU)/Down aerial

Hitbox visualization showing Kirby's down aerial, when landing.

Overview

A corkscrew dropkick. It has the slowest startup of Kirby's entire moveset on frame 18, but it has low ending lag. It consists of multiple hits, with the final hit being able to meteor smash. It has a landing hitbox on Kirby's sides that launches at a 60 degrees angle, which makes it a useful combo starter. It also has a large initial autocancel window. In spite of its low ending lag and ability to meteor smash in the final hit, it is unsafe on shield (being -12) and the final hit being unable to KO characters such as Jigglypuff near the ledge offstage at 155%. Other aerials such as his neutral air or forward air possess faster frame data, stronger knockback, wider combo opportunities, and more versatility in general. In short, while serviceable against characters with bad recoveries and for starting combos, other aerials outclass down aerial in most aspects.
