Adolphus Caesar

Emperor Adolphus Caesar was the young and spoiled child ruler of an alternate Rome that never fell. His titles included "Master of the Solar System and the Galaxy Beyond." After the Malevilus were defeated, the Fourth Doctor advised Vesuvius to send Adolphus to a boarding school on Cryos Four, run by an order of Lukronian Vorks who were very strict on discipline.

According to another account, Adolphus was sixteen when he met the Fourth Doctor, rather than a young child. (AUDIO: Doctor Who and the Iron Legion)
