Final Edge

Final Edge (, Final Edge) is the Mii Swordfighter's Final Smash.

Overview
It involves the Mii Swordfighter lifting their sword and unleashing many low-knockback crescents of random colors in a chosen direction. It is similar to and bears a resemblance to the Sword Beam from  franchise. Compared to Wii Fit, Final Edge is much weaker, each slash dealing mediocre knockback, designed to overcome foes with its sheer number of slashes and drag them offstage for a KO.

This Final Smash behaves slightly differently between both versions of Super Smash Bros. 4. Final Edge on the Wii U makes the crescents follow a wider path, giving it more vertical range and less accuracy than on the 3DS. In both versions, however, the Swordfighter can unleash a powerful blow from its sword to anyone very close to it as it initiates the attack. This hitbox can KO opponents at moderate damage percentages.

In Super Smash Bros. Ultimate, the move was given an aesthetic change, in the form of the Mii Swordfighter rapidly slashing their sword to release the crescents. The move now seems to be performed faster because of this. Unfortunately, the Final Smash has less range than it did before making it less consistent for KOs.

Trivia

 * Possibly as a result of being a Final Smash used for pushing opponents off-screen, much like Mario Finale, Doctor Finale, or, it is the only Final Smash used by a Mii Fighter that does not trigger Finish Zoom.
 * Final Edge is the only move in SSB4 to vary depending on whether it is used on or.
