Antodus

Antodus was a member of the Thal expedition to seek another way into the Dalek City via their water supply system. His brother was Ganatus.

Antodus became distressed after the death of Elyon and was reluctant to continue the mission. Ian Chesterton helped the Thals jump across a chasm in this system to progress by supporting the expedition with a rope tied around him. When it was Antodus' turn to jump, he missed, pulling Ian down. Unable to pull himself back up the rock face, he cut the rope and fell into the chasm, saving Ian's life. (TV: The Daleks)
