Porter

Porter "Paintergeist" Geiss is a poltergeist ghost who attends Haunted High, a school for ghosts and son of the Poltergeist. He appears in the TV special Haunted.

Free-spirited, rebellious, and honest, Porter has been labeled several times as part of the "bad boy" type due to spreading his graffiti art everywhere around the school, and has accumulated more "Detention Chains" than anyone else in school. Porter's nickname, "Paintergeist" comes from his love of art and loves painting on everything. Whenever inspiration strikes, he wastes no time in finding the nearest canvas, usually a wall, and painting an image in ghost paint. Despite Porter's art constantly lands him in trouble with Principal Revenant, he always remains upbeat, friendly, and cheerful, always looking for his next masterpiece. However, Porter's playful and laid-back behavior makes it hard for other to take him seriously unless he outwardly shows it. Porter proves to be crafty and observant, such as getting past the Hall Moanitors long enough to paint his artworks. Porter is also is the only student at Haunted High to notice the increase of detention chains that Principal Revenant been giving out unfairly. He also was able to steal the key Principal Revenant uses to transfer her chains to the students and plays along with her deal to betraying his friends in order to see how the key works and free them later.

Though sometimes coming off rude and often considers to be a troublemaker but he has a soft side, and greatly cares about his friends. Porter is very considerate whenever he's creating artworks, as he hates ruining other people's property, so he only paints using "ghost paint", a type of paint that fades away after a while, and only permanently paint something if he owns it. In In her Kiyomi Haunterly's dairy, Porter spray painted a touching haiku for her when he notices she been feeling down lately. In the Haunted, Porter offers to take on all the Detention Chains of the other students as Spectra Vondergeist and her friends work to stop Principal Revenant's plot to invade the Monster and pass off her punishment chains to innocent students.

Porter is a slim yet stocky build ghost with slime green skin and dark green hair with long bangs swept to the left. His limbs are fading away and transparent, and he has dark-green eyebrows that match his hair. Porter has intense blue eyes with two green sclera and dark blue pupils.

He wears paint-artist-inspired clothing that is colorful and looks like they have been painted; he wears a black shirt and black brick-pattern shorts with paint-like stains all over his clothes. He wears a shackle on his left wrist, and chains wraps around his waist, with two chains dangling on his sides. He wears blue shoes and has two painter spray cans of "ghost paint" attached to the chain suspenders on his shirt.
