Sir Pentious/History

Past
Sir Pentious was a brilliant inventor and supervillain during his lifetime.

He died in 19th Century London, specifically in the year 1888.

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.

When he tries to invade the Happy Hotel, Alastor steps in and takes him down by summoning his shadow tentacles.

However, at the end of the pilot episode it was revealed that Sir Pentious had miraculously survived the attack, but he was severely injured.
