King Boo

King Boo is an enormous, orb-shaped white ghost creature with fangs and a large drooling tongue, who wears nothing more than a golden crown on his head. He is the leader of the Boos and ghosts, and typically the arch-nemesis of Luigi. He is also an ally of Bowser and has aided him in his various schemes. He has succeeded in capturing Mario three times, as well as capturing Toads, Professor E. Gadd, and Princess Peach. Although not the biggest Boo, King Boo has some powers that the others lack, including materializing objects and spitting fire. King Boo's power is often directly proportional to the number of Boos in his vicinity. Though most of the year he is simply a mischievous and playful villain who enjoys scaring people, during the month of October he becomes dark, twisted, and somewhat sadistic. When taking on this alternate personality, his appearance changes, giving him dark shadows around his eyes which will glow purple, turning his tongue purple, and materializing a gem in his crown. This alternate personality loves trapping his foes in paintings as well as his stomach. Regardless of personality, King Boo resides in a giant manor known as the Twisted Mansion, inhabited by many other Boos. He seems to be somewhat lonely, longing for a proper partner who will love him, and not just because he's the king. King Boo is pansexual and very dominant, having a sixteen-inch, pink, tapered cock with heavy white balls. He is able to take on an anthropomorphic form, giving himself a musclegut body with proper arms as opposed to his usual nub-hands, a curling tuft of white hair atop his head, and even a fancy royal suit with a cape. King Boo is somewhat afraid of his October personality, worried that he might harm or scare away a potential lover, but during the rest of the year he is extremely loving and affectionate to those he cares for, not being a truly bad ghost, even thinking his subjects are cute. Despite being a ghost, he is not undead, having been born this way. In any form, King Boo has a wispy tail and can fly through the air as well as phase through solid matter. Even in anthro form, he never has legs, instead allowing the tail to encompass everything below his pelvis. His kinks are vore, brain-fucking, and of course, fearplay. He is able to swallow almost anyone whole and digest them as fast or as slow as he wants, as well as allow them to respawn afterwards. Since King Boo is a ghost, he can phase his penis into someone's body and fuck any part of them, including their brain.
