Boom Boom

Boom Boom, Bowser's nephew and fellow comrade, is typically one of Mario's more persistent foes and is often battled as a mid-boss in fortresses. He is strong and aggressive, with his main form of attack is running around while swinging his fists.

Appearance
Boom Boom has an orangy-yellow complexion, with a red shell with small spikes. He has no hair and two long, sharp teeth stick out his mouth. His is rather chubby and short, he also has huge fists, which increases his mobility in combat.

Personality
Boom Boom's general behaviour at times can be repulsive and vulgar, especially to his enemies. However, towards people he likes, he would act calm yet somewhat rowdy. He also has a way of words, where we would refer anyone to "cuz". He is also very half-hearted and anguished when he encounters a problem in his life, this is seen when Junior confronts him in Worlds Collide.

Powers
Invisibility/Camouflage: As seen in Super Mario 3D World, Boom Boom has invisibility powers. It is unknown if he was born with the power, or if it was given to him by Kamek, but it adds a lot of power to most of his attacks.
