Little Mac (USBIV)

Little Mac is a startable playable character in Ultra Smash Bros. IV and makes his second return in the series since Smash 4. He was confirmed during the Famicom Smash Week where some retro characters appear in the Nintendo Entertainment System with only one or less than two games, alongside with R.O.B., the Ice Climbers, Duck Hunt, Dr. Mario, and the newcomer Excitebike Rider and King Hippo, including Mr. Game & Watch. In his own series, Punch-Out!!, Little Mac is the main protagonist, alongside with the side-character, Doc Louis, for being his coach. Mac is a boxer with a small size. With help with his coach, he trains to be the best boxer in the world, and so that, he must face many competitors, bigger than his size, during boxing tournaments.
Little Mac has an alternate framewire costume where it's used in arcades from Punch-Out!! Both also use a pink jacket costume (for framewire, a green jacket) that appears in his games were he, and his coach, work-out together, similar to Bowser having alternate costumes as Dry Bowser.
Little Mac voiceclips were reused from Smash 4, only for the Japanese version of the game, Kosuke Toriumi reprises his role. While adding new voiceclips for the English version, Matt Harty reprises his role again, who did in Punch-Out!! for the Wii. Framewire Little Mac receives no voiceclips but sound-effect that are used in the NES or arcade games of Punch-Out!!.
Little Mac ranks the 88th place of the 103rd in the tier list, putting him at the top of the mid tier classment (C-) behind Chibi-Robo and after Excitebike Rider. And so on, Little Mac stays at the same spot as a mid tier character since Smash 4.
