Death's Head

Death's Head was a metallic life-form who worked as a 'freelance peacekeeping agent' (effectively, a mercenary, bounty hunter and assassin) in a number of dimensions and time zones. Death's Head described himself as a mechanoid, a designation not related to the Mechanoids, the enemies of the Daleks.

Profile
Death's Head did not take pleasure in killing, merely in being professional and financially astute, and possessed a rather pedantic personality. He was a habitual traveller between alternate realities, spending most of his career in universes other than the main one. At the time that he first encountered the Doctor, Death's Head had been enlarged to nine metres in height.

Some unspecified time after his enlargement, Death's Head worked as a freelance bounty Hunter. One of his targets was the Cybertronian Decepticon called Galvatron. After various dealings with the Cybertronians, Death's Head was released into the Time Vortex.

While travelling through the Time Vortex, Death's Head collided with the Doctor's TARDIS, forcing both to materialise. Death's Head attacked the Doctor, but was shot with a TCE and returned to his original size apparently uninjured. The Doctor eventually used the TARDIS to launch the mechanoid through time and space to the planet Earth in the year 8162. (DWM: The Crossroads of Time)


 * There is marginal evidence to suggest this version of Earth is in the main universe to the Doctor and Death's Head both encountering the scavenger Keepsake at a later point, but it could just as easily be Earth-616 or another as yet unidentified parallel.

Apart from a rather distant encounter at Bonjaxx's party he and the Doctor did not meet again for some time. (DWM: Party Animals)

Later, Death's Head attempted to claim the price put on the Doctor's head by Josiah Dogbolter, using a prototype time machine to track him down. However, Dogbolter meant to double-cross the mechanoid, hiding a nuclear device in the time travel unit to kill both him and the Doctor. The Doctor saved Death's Head from the bomb and in return the mechanoid decided not to complete the contract on the Time Lord... this time. (Death's Head #8)

Behind the Scenes
Death's Head was the lead character of a comic book published by Marvel UK, which (as described above) had several crossovers with Marvel UK's Doctor Who comic strip, thus tangentially placing Doctor Who (or at least the DWM comic strip version) within the Marvel Universe.
