Little Mac transforms into his hulking alter ego known as Giga Mac, then initiates a rush forward. If he connects, the move can trap opponents and trigger a single flurry of blows before the Final Smash ends.
- This version of Giga Mac joins all former "transformed moveset" Final Smashes (such as Giga Bowser and Wario-Man) in losing its player-controlled moveset in favor of a quick attack that returns players more promptly to normal gameplay.
- It is a clone of Jungle Rush, albeit with slightly less knockback to compensate for the added range potential.
