Rabbid Kong is a massive, ape-like Rabbid that appears as the end boss of Ancient Gardens in Mario + Rabbids Kingdom Battle. As his name implies, he is heavily based on Donkey Kong, right down to wearing his signature necktie. He is created by Spawny after Bowser Jr. convinces him to join him, and is subsequently fought by Mario and his friends.
When defeated, Rabbid Kong attempts to make his last stand by standing atop a wobbly block tower; however, Rabbid Peach 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 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.
