Final Cutter

Final Cutter is one of the attacks used by the Cutter ability in the Kirby series, and appears in the Super Smash Bros. series as Kirby's up special move. Like in its series of origin, Kirby pulls out a blade and slashes up into the air before flying back toward the ground. When Kirby lands the attack sends out a shockwave in front of him that also damages opponents. The move also has a meteor smash on the descent. The player can also influence Kirby's horizontal movement a little during the attack.

In Super Smash Bros. for Nintendo 3DS / Wii U this move has two customizable variants:

Wave Cutter creates a rock wave upon landing, which has more power and range than normal, but the blade can't deal any damage.

Upper Cutter executes quickly, dealing damage to those who are caught in the attack's path. However, upon finishing the jump, Kirby does not plummet straight down, but instead, enters a helpless state without affecting his horizontal mobility; this also removes the shockwave and meteor smash properties that Final Cutter has.
