Death's Head Interactive Archive

The Death's Head Interactive Archive was a supercomputer created by Hob over the course of three million years to track the life of Death's Head and related individuals. It was located on the space station Maruthea, located in the Time Vortex. (COMIC: The Incomplete Death's Head)

History
Hob was flung through time and space by the thermonuclear explosion of the Dogbolter Temporal Rocket the Seventh Doctor and Death's Head left at the Intra-Venus, Inc. headquarters. (COMIC: Time Bomb!, The Incomplete Death's Head) Hob believed his master, Josiah W. Dogbolter, also survived the explosion and he dedicated his efforts to searching through "every inch of the physical universe and every second of history" to find him. Hob focused on recording and investigating every moment of Death's Head's life to locate him and force him to find Dogbolter. The Seventh Doctor sent Death's Head II and Tuck to Maruthea to wrap up loose ends with Hob. Hob captured Tuck and connected Death's Head into the Archive's virtual world, forced to re-experience the adventures of his first self as recorded by the Archive.

At the same time, the original Death's Head as well arrived as Bonjaxx's Bar, which the Archive's scanner detected, alongside the Seventh Doctor and a future incarnation, much to Hob's delight. (COMIC: The Incomplete Death's Head) After a bar fight, (COMIC: Party Animals) Hob intended to coerce information out of the original Death's Head or kill him, but his later incarnation escaped the virtual world, and they defeated Hob together. Before the original Death's Head could create a paradox by fighting his future incarnation, the Seventh Doctor stunned him, revealed his manipulation of Death's Head's life, and returned the original Death's Head to Bonjaxx's bar.

According to one account, Dogbolter survived the explosion and continued to run Intra-Venus, Inc. with Hob before being exposed by the Twelfth Doctor and arrested. (COMIC: The Stockbridge Showdown)

Archive data
The Interactive Archive contained informational entries ("archive back-up scans") on groups or individuals Hob was monitoring due to their relationships with Death's Head. These included Dragon's Claws and the Doctor. The archive itself noted that these archives, particularly the Doctor's, were not very accurate due to Hob rewriting them to suit his own "deluded interpretation of real events".

The Doctor's entry depicted the fourth, fifth, sixth and seventh incarnations as "known aliases", with the Seventh Doctor being noted as the latest and "most deadly" known, and the Fourth Doctor as a "possible alias" (due to him not having encountered Dogbolter directly). The entry reported on his encounters with Dogbolter, including the Fifth Doctor's encounter with the Moderator and the Wrekka, (COMIC: The Moderator) the Sixth Doctor's encounter on Venus with a Whifferdill (incorrectly reporting his bounty of 250,000 mazumas as 750,000), (COMIC: The Shape Shifter) and the Seventh Doctor's encounter with Death's Head in possession of the Dogbolter Temporal Rocket. The archive also listed many "known confederates" of the Doctor, including Keepsake, Frobisher, John and Gillian Who, Ace, Ian Chesterton, Liz Shaw, Sarah Jane Smith, Peri Brown, Leela, Miss Young, Sharon Davies, and Death's Head.
