- For fighter info, see Little Mac (SSBWU/3DS).
Little Mac (リトルマック Ritoru Makku) made his appearance in the game Punch-Out!!. Like his name states, he is a very little character. Despite his size, he entered a boxing tournament and was able to become a champion. After a long time without being heard of, he makes an appearance in Super Smash Bros. Brawl. Little Mac is an Assist Trophy helper in the game. When summoned, he dashes about the stage to opponents, attacking by dealing two straight punches and an uppercut. The punches do a good amount of damage and the uppercut is devastating because it has very high power (25% damage) and knockback, and is an instant shield breaker. If at the right damage percentage, Little Mac can easily knock out opponents for the one who summoned him, but he is unreliable as he often falls off the stage. The punching sound effects from Punch-Out!! can be heard as Little Mac attacks. Little Mac receives his own trophy in the game, like all other Assist Trophies. Recently, Little Mac appeared in the fifth installment of the Punch-Out!! series for the Wii, released one year after Brawl.
Little Mac appeared as an assist trophy in Super Smash Bros. Brawl.
Little Mac was confirmed to be a playable character in Super Smash Bros. for Wii U and 3DS on February 13, 2014 in a Nintendo Direct. One new feature he has is a power meter at the bottom of the screen, which when charged up, can be a one-hit KO.
A lightweight scrapper from the Bronx. After meeting with a former boxing great named Doc Louis who fell from glory, Mac takes Doc on as his coach, and together the pair try for the championship belt in the WVBA. Little Mac works his way up the ranks of the WVBA, taking out foes several times his size. By landing multiple blows, Little Mac gains a "☆" uppercut.
- Given that Punch-Out!! is itself a fighting game series, Little Mac is the first character in the Super Smash Bros. series to have originated in a fighting game. Consequently, he also belongs to a group of characters who have also appeared in another fighting game, which includes Donkey Kong (whom he previously appeared with in Punch-Out!! for the Wii), Link, Snake, Sonic and Mega Man.
- Little Mac is the first Assist Trophy in Brawl to become playable in later installments.
