Giant Donkey Kong

Giant Donkey Kong, also referred to as Giant DK, is a recurring minor boss in the  series.

In Super Smash Bros.
Giant DK first appeared as a non-playable character in Stage 6 of Super Smash Bros.' 1P Game. Giant DK has a large amount of knockback resistance, while his own attacks have increased knockback capable of KOing opponents more easily on top of having increased range due to his size, making him a formidable opponent; however, the player is given two regular-sized AI partners to help out. On higher difficulties, Giant DK behaves more similarly to a level 9 CPU while the player's partners are lower in level. It is possible to exploit Giant DK's AI, making him walk back and forth on the top platform, similar to Metal Mario along with his size making him a larger target to attacks. However, it is harder due to AI partners jumping into him or attacking him which will often interfere with his pattern.

Due to being considered as a character separate from regular, Giant DK does not appear in a different color when a player- or AI-controlled regular DK fights him. While Giant DK has all of regular DK's color variations (including the Team Battle-exclusive green palette), they are only accessible through the debug menu.

As a playable character

 * Main article: Giant Donkey Kong (SSB)

It is possible to play as Giant DK using a debug menu code or GameShark. He is distinguished by having drastically increased attack range and being heavier than the regular, notably with regards to his jab. He is, however, prone to being chain grabbed, such as by or, and his grab doesn't reach directly in front of him. Despite being his own unique, separate character, he has the exact same head icon as the original.

In Super Smash Bros. Melee
In Melee, Giant DK is essentially regular with a permanent Super Mushroom upgrade (and can thus be temporarily playable that way or played permanently using Action Replay's Auto-Mushroom cheat). Giant DK appears at the end of the Stage 2 of Adventure Mode, after defeating two tiny Donkey Kongs. Giant DK is also very exploitable; by standing perfectly still or moving slightly towards the edge, depending on character, it is possible to bait him into using an f-air or n-air and falling into the water, resulting in a free win. This is much more likely on higher difficulties due to the more aggressive AI, and is a common speedrunning tactic for this stage. Additionally, in, like all giant characters, Giant DK has a chance of appearing on Stage 5 as a random giant opponent.

Giant DK appears controlled by the player in Event 2: Lord of the Jungle.

Additionally, Event 25: Gargantuans features an immensely large Donkey Kong (over twice as large as the normal Super Mushroom DK) as an opponent, while the player is a Giant Bowser, with a super tiny and  also present.

In Super Smash Bros. Brawl
Giant DK returns in Brawl in a similar fashion as in Melee, as a regular permanently equipped with a Super Mushroom. Giant DK appears in four event matches: in Event 9: The Monster Beneath the Earth, if the player can't KO the two s in time, they must fight Giant DK; in Event 22: Monkeys Unite, Giant DK appears as Diddy Kong's ally to defeat and ; in Event 27: Three-Beast Carnage, Giant DK returns with Giant Bowser and Giant, attacking New Pork City; finally, in Co-Op Event 14: The Dark Guardians,  and  must defeat Giant Charizard and Giant DK, again on New Pork City. If counting both events and co-op events in Brawl, the aforementioned events are Giant DK's only appearances in Brawl.

Unlike the other playable characters (along with the characters and ), Giant DK does not appear as an opponent in, making this the only game in which he does not appear in Classic Mode.

In Super Smash Bros. 4
Giant DK is once again one of the possible random giant characters in. Giant DK can appear in in a giant Special Smash or Special Orders.

In Super Smash Bros. Ultimate
Giant DK appears as the boss of 's Super Smash Bros.-themed route, in reference to his original 1P Game role.

Origin
The closest analogue to Giant Donkey Kong in the series is the final boss battle of  for Game Boy, where the title character used Super Mushrooms to become much larger and fought Mario atop the Tower that comprised World 9. In this appearance, however, Giant Donkey Kong was significantly larger relative to Mario than his depiction in Smash.

Alternatively, Giant Donkey Kong's size may simply be a reference to one of Donkey Kong's inspirations,.
