bowser peach
A prototype design found in the art book of Super Mario Odyssey. She was to be the Captured form of Princess Peach, possessed by Bowser when he used a hat that worked similar to Cappy.
The comic that introduced her was fairly sketchy, but her most discenerible character traits were a green hat, a green dress, pointy ears, and red hair styled similarly to Bowser's own. She has humanoid claws in place of hands, and has two fangs.
