Jagganth Daiki-Nagata

 was the leader of a human military rescue team in the 38th century assigned to investigate why all contact had been lost with Le Verrier space station in orbit of Neptune. Upon encountering the Doctor and Clara on Le Verrier, Nagata instantly assumed that they had something to do with the disappearance of the station’s crew. However, with the Doctor’s help she soon discovered that the truth: the crew had been consumed by their own sleep dust. Having taken the Morpheus process for granted whilst on Triton, Nagata was horrified to discover that the pods also evolved human sleep dust over time to become a sentient lifeform in the shape of the Sandmen. Aiding the Doctor in determining that whilst the lumbering Sandmen appeared blind, their visual receptors were being hijacked by the dust, she discovered that everyone who had used the Morpheus pods was now a spy for Gagan Rassmussen.

Nagata was ultimately the only one of the Le Verrier crew or rescue team to survive the Morpheus incident. (TV: Sleep No More)
