Anton (The Enemy of the World)

Anton, along with Rod and Curly, were members of Giles Kent's plot to take down Ramón Salamander. In 2018, Anton, Rod and Curly mistook the Second Doctor for Salamander and attacked him in their hovercraft, ignoring Astrid Ferrier's orders to hold their fire.

When Astrid helped the Doctor and his companions escape, Anton and Rod took her helicopter and chased them down. They were unaware that they had damaged the helicopter when Astrid was piloting it, and they were killed when it exploded. (TV: The Enemy of the World)
