Constantine I

Constantine, also called Constantine Augustus, was an emperor of Rome.

Biography
In 312, Constantine was at war with Emperor Maxentius over the right to claim the title of sole emperor of Rome. Constantine won the battle when Maxentius was drowned in the Tiber by Entity possessed Cybermen. He intended to face the Cybermen with his army, but was talked out of it by the Eleventh Doctor and Alice Obiefune. Later, he saw what he believed to be the face of the Christian God in the sky, but in reality, it was the Doctor speaking through the illusion of the Entity. (COMIC: Conversion)
