Borusa (Battle for the Universe)
From Tardis Wiki, the free Doctor Who reference
An incarnation of Borusa was one of four malevolent Time Lords, along with Morbius, Omega and the Rani, who joined the Master in opposing the Doctor in a multi-sided battle for control of the universe, with the Doctor, the Master, Davros and a Cyber-Controller all vying for control of artefacts and locations which would make them masters of the cosmos.
