Ross (Into the Dalek)

Ross was a Combined Galactic Resistance soldier serving aboard the Aristotle. He was shrunken by a molecular nanoscaler and went inside "Rusty”, a Dalek that had been damaged and turned good, along with the Twelfth Doctor, Clara Oswald, Journey Blue, and Gretchen Carlisle. He was killed by the Dalek antibodies. (TV: Into the Dalek)
