Kirby (SSBB)/Back aerial
Kirby kicks backward with both of his feet, dealing 12% damage on the first frames, then 9% on the later frames. Has sex kick properties, but the hitbox lasts shorter than other sex kicks. It has good range with a slightly disjointed hitbox, and is good for spacing. It is Kirby's best approach option (although still poor), and Kirby players commonly approach while jumping backwards (via RAR), using the back aerial when opponents get close. Can KO at percents under 150% when fresh, but the move will usually be stale because Kirby players use it often. However it can still KO through edgeguarding or gimping, and can perform Fence of Pain techniques. It has very low start-up lag, as well as low ending lag and almost no landing lag. It is considered Kirby's best aerial and one of his best moves overall due to its usefulness both offensively and defensively, as well as its great edgeguarding capabilities.
