Princess King Boo Rule 34

Princess King Boo is a fan-created character from the Mario series, resulting from King Boo using the Super Crown item, similar to the popular Bowsette transformation. In this form, King Boo adopts a regal, feminine appearance reminiscent of Princess Peach, often featuring a white frilled dress with a collar or choker, elbow-length gloves, and sometimes thigh-highs. She has long white hair, very pale skin, and red or purple eyes. Her accessories include a crown, spherical earrings, a collar jewel often as a pendant, and occasionally a chest jewel. She retains King Boo's sharp teeth and frequently sticks out her tongue, often posing in a ghostly or claw-like stance. Fan artists typically depict her alongside Bowsette as fellow rulers, or with Luigi and Princess Daisy, mirroring the Bowsette-Mario-Peach dynamic. Common tags highlight her gloves, facial hair (a nod to King Boo's mustache), crown, white hair, jewelry, earrings, and breasts. The character was initially popularized by artist oshiruko_(tsume) and is preferred over similar Boo transformations.
