Spawny

Spawny is a Rabbid thar appears in Mario + Rabbids Kingdom Battle. In the Mushroom Kingdom, he is differentiated from other Rabbids by his white muzzle, blue belly, and ears, and the goggles that cover his eyes. He has the power to fuse other beings with Rabbids, doing so to create the Pirabbid Plant; however, said power is uncontrollable, and activates whenever he's stressed.

His name was given to him by Bowser Jr., who sought to use his powers to take over the Mushroom Kingdom.

Although he is a major catalyst for the events of the game and forms an alliance with Bowser Jr., it is unknown if Spawny is evil.

Spawny started out as an ordinary Rabbid. However, when he and many other Rabbids were transported to an unspecified location, Spawny stole the SupaMerge and used it to fuse other Rabbids with objects, doing so to create Rabbid Peach and Rabbid Mario. When Spawny enters the Mushroom Kingdom however, his appearance is differentiated from the other Rabbids.

Personality
When he was still a regular Rabbid, Spawny was mischievous, curious, and playful like his fellow rabbids. Always causing trouble without thinking about the consequences. After his transformation, Spawny became timid, naïve, and childlike. This causes Bowser Jr. to take advantage of him, pretending to be his friend so he could use his abilities. Because his power comes from fear and stress, Spawny has little to no control of his abilities.
