PZ9 is the leader of Project Zorgo, a group of hackers. He kept you around since you would help him. He had sent the hackers out on a mission to find the spy ninjas. He wears the top half of a Project Zorgo mask. He would let you be the only one allowed to call him by his real name, Melvin

PZ9 was walking back and forth since he was bored and didn't know what to do while he waited. It was just you and him in the safe house
