Mega Rabbid Kong

Mega Rabbid Kong is the corrupted alter-ego of Rabbid Kong featured in the Donkey Kong Adventure expansion of Mario + Rabbids Kingdom Battle.

Mario + Rabbids Kingdom Battle
In Mario + Rabbids Kingdom Battle, Mega Rabbid Kong fights Donkey Kong and his allies twice. He is first fought at the end of the Jungle. When the group first sees him, Donkey Kong attempts to rapidly punch him, only to be knocked away. Rabbid Peach then teases Mega Rabbid Kong by petting Donkey Kong, enraging Mega Rabbid Kong. His introductory tagline for this battle is a reference to a line in the DK Rap. ("He's bigger, faster and stronger too!")

In his first battle, Mega Rabbid Kong is initially immune to all attacks due to him draining a literal health pool known as the Megabug Pool to recover. He attacks by moving a few cells to the closest character, then launches an uppercut which can Bounce the character caught in the attack. If the character is too far from Rabbid Kong, he will instead attack by throwing a Bwananarang. In order to attack Mega Rabbid Kong, Donkey Kong and co. must attack him directly, or the Megabug Pool, or both so that the Megabug Pool is drained either way. This can be done a variety of ways, one of which involves Donkey Kong throwing a TNT Barrel at a target.

Once the Megabug Pool is completely drained, Mega Rabbid Kong escapes as the Megabug Pool explodes, collapsing Donkey Kong and co. into the Dungeon before they can escape as well.

Mega Rabbid Kong is encountered again at the end of the Dungeon. When he sees Donkey Kong and co., he fuses his remaining Bad Bananas together into a two-sided hammer, which he uses to create a whirlwind before eventually slamming into the ground.

In his second battle, Mega Rabbid Kong now has his two-sided hammer to contend with. He attacks by creating a powerful whirlwind that Pushes characters, then moves a few cells to either throw one of his Bad Bananas like a Bwananarang, or glide with his hammer to slam it down at a certain point. Donkey Kong and co. must attack him normally until he loses 1000 HP, at which point Mega Rabbid Kong's HP bar will go haywire. Mega Rabbid Kong will deploy a shield as several panels appear. Donkey Kong and co. must then step on all of the panels to unchain a golden Blast Barrel, which they can then use to defeat Mega Rabbid Kong for good.

Afterwards, Rabbid Kong reverts to normal. Rabbid Peach will grab a Banana to seemingly attack Rabbid Kong as he cowers in fear, but she instead offers the Banana to him, enlightening his spirit.

Super Smash Bros. Ultimate
Mega Rabbid Kong, simply referred to as Rabbid Kong, is featured as a Novice-class Attack-type primary spirit in Super Smash Bros. Ultimate. When equipped, it increases the playable character's weight during battle. 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.
