Marcus Scarman

Marcus Scarman was an English archaelogist working in Egypt and brother to Lawrence.

He lived in the same village as his brother Laurence, in a priory that would later be burned down and used as UNIT HQ. Finding the Black Pyramid which served as the prison of the Osirian Sutekh, he died, but his corpse was re-animated and used a vessel of Sutekh's power. Scarman (or his body) returned home via a space-time corridor contained in an Egyptian sarcophagus.

He killed Namin, Sutekh's servant, and 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)
