The Phantom of the High School Musical was the disguise of Coach Hayes.
The Phantom is a costume with green skin, a white mask half, red eyes, black hair, and a blowing magenta cape wrapped around his neck. He wears a tuxedo and has a massive build compared to any member of Mystery Inc.
He keeps his personality reasonably dramatic to keep up the identity of a high school phantom. He even sings when hurt. Still, he is a cunning coach under the mask with a good plan to win the sports carnival.
Powers and abilities
His powers and abilities consist of wiring on the roof to make it seem like he's flying, glow effects to make him look powerful, and a great deal of physical strength and health for a normal man.
