Death's Head (series)
Death's Head was a comic series published by Marvel UK across various comic books, such as Death's Head (1988) and Death's Head (2019). It is a part of the larger Marvel Multiverse. The series centres around the titular Death's Head, who first appeared in the Transformers UK comics, although not every Death's Head story is considered part of the Death's Head series. For a full list of the character's stories as covered on Tardis Wiki, see Death's Head/Appearances.
While not every issue in the series is covered by Tardis, the complete 1988 run was reprinted in The Incomplete Death's Head, which is covered by the wiki.
Crossovers
Various instalments of Death's Head contained elements originating from Doctor Who and Doctor Who Magazine, such as the Seventh Doctor and Keepsake's vulture, thus constituting official crossovers with the Doctor Who universe. Additionally, various instalments in the series were reprinted in The Incomplete Death's Head, which also involved DWU elements, thus constituting further crossovers due to the linking narrative. Outside of the actual Death's Head comics, an additional narrative - Synchronicity II - also crossed over with the DWU.
The following Death's Head stories involved DWU elements and are thus covered on this Wiki:
