Rabbid Kong

"We would like to introduce a new friend of ours. He's the 'top banana' around here."

- Bowser Jr.

Rabbid Kong is a massive, ape-like Rabbid that appears in Mario + Rabbids Kingdom Battle as the end boss of Ancient Gardens, as well as the main antagonist of the Donkey Kong Adventure expansion. As his name implies, he is heavily based on Donkey Kong, right down to wearing his signature "DK" necktie. However, Rabbid Kong's posture and walk style are more realistic and more comparable to those of a real life than Donkey Kong's more cartoonish movements.

Mario + Rabbids Kingdom Battle
Rabbid Kong is created by Spawny after Bowser Jr. convinces him to join him, and is subsequently fought by Mario and his friends.

Rabbid Kong's first move is to create a shock wave on the battlefield that deducts 10 HP from each heroic character, and the move also knocks them back unless they have full cover. To damage him, one of the characters must approach him, which will cause the pressure plate in front of him to drop his banana hoard and go ballistic as a result, making him an easier target - however, he will also hit the nearest character with a much stronger attack. To avoid this, Luigi or Rabbid Peach can alternatively deploy a Sentry towards the pressure plate, allowing all three heroes to attack Rabbid Kong while simultaneously protecting them from his stronger attack. When his HP is depleted, Rabbid Kong will move to another portion of the battlefield and replenish himself with a fresh banana hoard, repeating the process. He is defeated after the third phase. Three Garden Ziggies support Rabbid Kong in the first phase, followed by two Garden Hoppers in the second phase and one Garden Smasher in the third phase.

When defeated, Rabbid Kong attempts to make his last stand by standing atop a wobbly block tower; however, Rabbid Peach humorously knocks it over (after Mario tells her not to touch it), causing Rabbid Kong to plummet down to his defeat, after being in a selfie with Rabbid Peach.

Rabbid Kong returns in the Donkey Kong Adventure DLC pack as the main antagonist. There, he gets revenge on Rabbid Peach by trampling her into the ground, but with that, he sets Donkey Kong and Rabbid Cranky against himself. He eventually is corrupted into his large alter ego thanks to the Bad Bananas, but reverts to normal once the Bad Bananas are turned back into regular Bananas, and makes amends with the group.

Super Smash Bros. Ultimate
Rabbid Kong, although depicted in his Mega Rabbid Kong form, appears in Super Smash Bros. Ultimate as a Novice-class Attack-type primary spirit. When used, the spirit increases a fighter's weight. In World of Light, the Rabbid Kong spirit is encountered west from the area with the mushroom platforms on the Light Realm map. To earn the spirit, the player has to fight a white Donkey Kong wearing the Bunny Hood on the 3D Land stage.

Trivia

 * Rabbid Kong's battle theme is an arrangement of the music heard in the stormy part of Jungle Japes in Donkey Kong 64, itself an arrangement of DK Island Swing.
 * As shown in early prototypes of the game, Rabbid Kong was supposed to perform a dab upon successfully landing a move, but this was removed by the final version of the game, and was instead given to Luigi.
 * In the  episode Gorilla Rabbid, there is a similar-looking Rabbid who also references Donkey Kong through barrel-throwing, akin to the arcade game.
