Harrods

Haroldson, more commonly called Harrods, was a tramp who was often seen around the New World University campus, and lived in a disused shack.

Biography
Haroldson's nickname "Harrods" derived from the fact that he was fussy about where he slept. He was a Flight Sergeant in the RAF until he was left homeless after his squadron was disbanded.

He helped Daniel Hinton escape from the forces of the Great Intelligence and later saved Brigadier Lethbridge-Stewart from an attack by the Chillys (the dazed Brigadier at first thinking Harrods was the Doctor regenerated once again), teaming up with him to combat the Great Intelligence and its Yeti at New World University.

Later, when Hinton was turned into a Yeti, Harrods sacrificed his life to save the Brigadier. (HOMEVID: Downtime, PROSE: Downtime)
