Henry (Kill the Moon)

Henry was an astronaut who, under the command of Captain Lundvik, traveled to Earth's Moon to blow it up with nuclear missiles. When he went to explore the lunar surface, he was attacked by one of the Moon's spider germs, which attacked and killed him. The Twelfth Doctor later found him, dead, his spacesuit ripped open and his skull grinning from the inside. (TV: Kill the Moon)
