Zygon (The Zygon Invasion)
From Tardis Wiki, the free Doctor Who reference
A Zygon was captured by the Twelfth Doctor and Osgood. Under a Zygon base in Turmezistan, this Zygon attacked the Doctor while he was rescuing Osgood from her chains with his sonic sunglasses. However, a cave-in trapped the Zygon, prompting the Doctor to secure it and bring it aboard Boat One, where it was questioned. It refused to tell the Doctor its name but revealed the Zygons' new intention: to rule the world. It told the Doctor that the Zygon invasion had already taken place and that the plane would never land. (TV: The Zygon Invasion) Boat One was shot down by Bonnie. (TV: The Zygon Inversion)
