Mummy (Dr. Who's Time Tales)

A mysterious living mummy confronted John Kelly when he broke into an American museum to try and hide from the police. Speaking in English, it advised him to hide inside the mummy's own sarcophagus. After some persuading, Kelly agreed, but only realised the mummy's true purpose after he found himself transported back in time from having stepped into the "mummy case", ending up forced to work as a slave on the construction of the very pyramid from which the mummy and sarcophagus would later be unearthed, meaning the mummy's advice had been anything but altruistic.

Behind the scenes
Dr. Who's Time Tales does not explicitly state whether the mummy is actually an undead human. Although this was doubtless the intention behind Man in the Mummy Case! (the American comic story from which the story was adapted), the newfound DWU context of the narrative, which makes the time-transporting sarcophagus reminiscent of an Osirian lodestone as seen in Pyramids of Mars, may suggest that the mummy is in fact a Servitor.
