Kirby (SSBU)/Down special
Upon usage, Kirby transforms into a rock, which makes him invincible to attacks that deal less that 25%, but he can still be grabbed while he is still using it. It deals high damage and knockback, especially in the air, and the aerial version has super armor frames, while the landing hit is a semi-spike, and it can also be useful for mindgames. It can combat juggles at high percents, but only if he is at a certain distance away from his opponent. Stone can also be used as an occasional landing or edgeguarding tool. However, due to its high startup and endlag, it can be punished for overusing the move. As such, stone is best used situationally.
