Giga Mac (ギガ・マック, Giga Makku) is Little Mac's Final Smash.


After transforming into Giga Mac, Little Mac can still use his normal moves, but their power is significantly increased, similar to Giga Bowser and Wario Man. His Smash attacks, in particular, have a significant damage boost, being able to one-hit KO at 40% damage. The two attacks that are different for Giga Mac are his neutral combo, which is slower but deals more damage, and Straight Lunge, which has its charge time reduced in half. Giga Mac's aerial attacks, however, remain the same as Little Mac's.

In addition to increasing his damage input, Giga Mac has similar properties to Giga Bowser, being immune to launching, flinching, or shield breaking, but can still take damage. However, for the duration of the transformation, the Power Meter is disabled, making Giga Mac unable to use the KO Punch.


Giga Mac first appeared in Punch-Out!! for Wii. In the game, Little Mac becomes Giga Mac after one of the players fills up a blue bar by punching the other player at certain times.
