Ultra Sword

Ultra Sword is a Super Ability from Kirby's Return to Dream Land. It is an upgraded form of the Sword ability.

Super Smash Bros. series
In the Super Smash Bros. series, Ultra Sword appears as Kirby's Final Smash in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate, replacing Cook Kirby from Super Smash Bros. Brawl. When activated, Kirby pulls out a giant sword and slashes to trap opponents, then slashes them multiple times before the sword grows larger for the final attack, dealing massive damage and knockback. If the first swing does not connect with any opponents, the Final Smash fails.

In Super Smash Bros. for Wii U, there is a trophy of Kirby using Ultra Sword, and it can be obtained by clearing All-Star Mode with Kirby.
