Tommo (The End of Time)
Tommo was a homeless man who lived in the wastelands of London in the 21st century. He was friends with a younger homeless man called Ginger. On Christmas Eve 2009, he and Ginger bought burgers at Steven's Point. Another homeless man bought a burger. He and Ginger both remarked that he looked like Harold Saxon. They were then both eaten by the hooded man, who in reality was the Saxon Master scavenging for food. (TV: The End of Time)
While looking for a segment of the Key to Time, Missy (claiming to be the Doctor) took her past self to various points in their timeline. One of these was when the Master was chasing Tommo and Ginger. (COMIC: The Master Plan)
