Sir Pentious/History

Past

As a demon, his main goal is to gain complete control of Hell, though he has failed multiple times so far. He is an expert with building and working with machines and devices, and he has an army of sentient egg demon henchmen known as the Egg Boiz, who were created with the help of another individual.
