Giant Donkey Kong is a recurring enemy in the Super Smash Bros. universe.
He first appeared in Super Smash Bros.' 1P Game as a giant opponent. DK has little knockback when attacked, while his own attacks send opponents flying, making him a formidable opponent on higher difficulties. Because of this, players face him with two regular-sized allies. It is also possible to play as him using the Debug menu code or change 1 player to specific character.
Extra appearances include an immensely large version (over twice as large as the normal Super Mushroom DK) that appears in Event 25: Gargantuans against the player controlling a similarly-sized Bowser, plus a super tiny Mario and Peach.
Giant DK returns in Super Smash Bros Brawl. He appears in Event 9: The Monster Beneath the Earth. If the player can't KO the two Diddy Kongs before a certain point, they must fight Giant DK. Also, in Event 27: Three-Beast Carnage, Giant DK returns with Giant Bowser and Giant Charizard, attacking New Pork City. Finally, in Co-Op Event 14: The Dark Guardians, Ganondorf and Wolf must defeat Giant Charizard and Giant DK, again in New Pork City.
Giant DK makes yet another appearance in Super Smash Bros. Ultimate, as Jigglypuff's final boss in Classic Mode, reflecting its route that resembles fighters that appeared in Super Smash Bros.
