Marcus Scarman

Marcus Scarman, brother to Lawrence, was an English archaelogist.

He lived in the same village as his brother Laurence, in a priory that would later be burned down and used as UNIT HQ. Marcus found the Black Pyramid in Egypt, which served as the prison of the Osirian Sutekh. Sutekth killed him but animated his corpse and used it as a vessel of his power. Scarman (or his body) returned home via a space-time corridor contained in an Egyptian sarcophagus.

He killed Namin, Sutekh's servant, and, with a small number of Osirian service robots at his command, set about doing Sutekth's will. He killed his brother Marcus and, witnessing the destruction of the Osirian war missile, traveled to the Pyramid of Mars with a possessed Doctor and Sarah Jane Smith to release Sutekh from the Eye of Horus. Despite the fact Sutekh was freed, the Doctor was able to defeat him, after which Sutekh relinquished his hold on Scarman's corpse, allowing him to die. (DW: Pyramids of Mars)
