With the movie studio being haunted by mummies and ghosts, Robert Zabrinski asked him to buy the studio from the Milton brothers, but they refused to sell the lot.
He was unmasked as the Red Knight. He wanted to buy a film studio from the Milton brothers for Greenwood development, so he dressed as the Red Knight and summoned monsters from the Tome of Doom to scare people away.
