Kirby (SSB4)/Back aerial

Hitbox visualization showing Kirby's back aerial.

Overview

Kirby quickly crouches in midair, then does a back kick with both feet. A sex kick. The move has very low startup lag and good range, with a slightly disjointed hitbox. It is Kirby's fastest and strongest aerial, being the only one that can kill an onstage opponent. It can also be used for a Fence of Pain. The low lag and hitboxes make this one of his most reliable spacing moves. The knockback of the move means it won't start any combos, but it is a solid finisher. Overall, like in every game, it is a defining part and important tool in his metagame.
