Carl Tyler

Carl or Jim Tyler (PROSE: Doctor Who and the Dalek Invasion of Earth) was a freedom fighter on Earth during the Daleks' invasion and occupation.

Tyler and David Campbell rescued Barbara Wright and Susan from the Daleks and took them to their hiding place.

Tyler resisted Dortmun's plans to attack the Daleks, as they didn't have enough men. In spite of his reluctance, he led the attack on the Dalek flying saucer. He was one of the few survivors of the attack. After the failed attack, he decided that London was too dangerous for them to remain, and stated he would look for more survivors and head north.

Tyler met up again with David, Susan and the First Doctor. He saved Susan from an alligator in the sewers.

He accompanied the Doctor to the Dalek control centre and helped to evacuate the miners. (TV: The Dalek Invasion of Earth)
