Giga Mac

Giga Mac (, Giga Mac) is 's Final Smash in Super Smash Bros. 4.

Overview
Little Mac transforms into his hulking alter ego known as Giga Mac. Giga Mac can be freely controlled, moving and attacking normally with a moveset similar to Little Mac's.

In Super Smash Bros. 4
In SSB4, Little Mac flashes in a ball of green light before transforming into a hulking form known as Giga Mac. He retains the same moveset, but with a considerable upgrade in power and reach, along with a mobility increase. His smash attacks in particular can deliver high amounts of damage, and offer incredibly high knockback scaling (except for the low angled forward smash, which still deals low knockback), capable of KOing most of the cast below 40%, with the forward angled forward smash being capable of one-hit KOs.

Only four of Giga Mac's attacks have different attributes compared to Little Mac: namely, his neutral infinite is significantly slower but deals more damage, his forward tilt transitions to the second hit slower (though the move's effectiveness remains unchanged), the charge time of Straight Lunge is reduced by half, allowing it to be fully charged in under a second, and Slip Counter's counterattack deals a minimum of 30% damage while still possessing the 1.3x damage multiplier.

Giga Mac has the fastest air speed of all fighters (including the other transformation Final Smashes), despite Little Mac's average air speed. He also has the fastest walking speed of any fighter, but his running speed is only increased enough to surpass ; he still loses to and Wario-Man. Giga Mac's aerial attacks also gain a damage and knockback boost; while they are still considerably weaker than Giga Mac's grounded moves, they become capable of KOing at the 90-100% range at the edge of Final Destination.

Like, Giga Mac cannot be launched, does not flinch when attacked, and cannot have his shield broken, but he can still receive damage, and can still take knockback from windboxes. Additionally, Giga Mac is unaffected by Super Mushrooms and Poison Mushrooms, making it impossible for players to alter his size during a match. Likewise, Metal Boxes also have no effect on Giga Mac.

While Little Mac is under the effects of Giga Mac, his Power Meter is temporarily disabled and Doc Louis will not call out during Giga Mac's taunts. Giga Mac reverts back to Little Mac after 11 seconds have passed.

Origin
In the two-player mode of Punch-Out!! for the Wii, both players control a Little Mac; either can turn into Giga Mac after punching the opponent enough times in a certain area. If they do, the game then shifts from two evenly-matched Little Macs fighting in split-screen to gameplay resembling the single-player mode, with Little Mac fighting a larger and slower Mac. The player controlling Giga Mac gains slower but stronger attacks, in addition to a taunt.

In Punch-Out!! for Wii, there is another Giga Mac color scheme used by the brown haired Little Mac controlled by the second player. However, in Super Smash Bros. 4, Giga Mac only has one color scheme regardless of the costume that Little Mac had prior to using the Final Smash, like other transformation Final Smashes.

Trophy
Giga Mac has a trophy that only appears only in the Wii U version of Super Smash Bros. 4.

Spirit
Giga Mac also appears in Super Smash Bros. Ultimate as a Legend-class primary spirit.

In Adventure Mode: World of Light, Giga Mac is presumably one of the countless spirits captured by Galeem during his takeover of the universe. After Galeem's defeat, Dharkon takes control of Galeem's spirits, including Giga Mac. After Dharkon's defeat, he flees to the final world, with Galeem following soon after. In the final world, Galeem and Dharkon wage war against each other using their captured spirits, with Galeem taking control of Giga Mac.

Giga Mac's Spirit Battle uses a Giant puppet fighter and is fought on the Boxing Ring stage. During the battle, Little Mac is equipped with super armor, referencing how Giga Mac cannot be flinched when attacked as a transformation Final Smash in Super Smash Bros. 4.

Trivia

 * In the E3 2014 demo, due to a glitch, if Giga Mac touched a spring, he would be stuck in his bind pose for the remaining duration of the Final Smash.
 * While the transformation is a size increase for Little Mac, Giga Mac is actually only slightly larger than.
 * Since windboxes still affect Giga Mac, it is possible to KO him off the upper blast line (such as with Greninja's down taunt when Giga Mac is in the air); however, since he does not have a screen/star KO animation, this will always result in a blast KO.
 * Even though Wireframe Mac uses 8-bit sound effects for his "voice", Wireframe Mac still emits the vocal sound that Little Mac emits upon transforming, and still has the default Giga Mac texture. However, the sound effect that plays when Little Mac begins transforming (during the ball of green light) is completely removed in.
 * Aside from the obvious technical reason, Giga Mac not having a wireframe variant might be because the transformation was introduced in the Wii version of Punch-Out!!.
 * Interestingly, the speed multiplier of Training Mode does affect how long Giga Mac lasts, despite the fact that his duration formula is the same as that of Wario-Man and Mega Lucario.
 * Doc Louis will not be heard while taunting as Giga Mac.
 * Giga Mac is one of the few Final Smashes to be a Spirit.
