Antagonista

Antagonista was a planet which was home to hordes of hungry zombies. Charles Abbott teleported Sammy Jones to Antagonista using Incredulitas 4. He then wrote a series of books based on what happened.

After discovering Sammy's fate, the Twelfth Doctor and Eliza Jones came to Antagonista and rescued Sammy from zombies which were about to eat him. (COMIC: Shock Horror)
