He is a clone of Zack Max, but he's shown to be more powerful than him even as a clone. He's the leader of all simulations no matter what they are. He's also the leader of the gods of the simulations. Alot fear his power so they cheat their simulations. Tthulhu for example had made it that if Zack Scientist joins, everyone in that simulation will die.
When he discovered the Simulation, he was shocked. He had papers reading about the location. He couldn't enter because it would just kill everyone. He was angered due to how corrupt it is. He noticed the leader being Zack Max, looks exactly like him.
