Tor was a Xeron rebel who fought the Moroks in the Space Museum. When he, Sita and Dako encountered the First Doctor, Sita hit him. Believing the Doctor to be unconscious, Tor and Sita went off to find something to bring him round. They later found Vicki and took her to safety. Tor sent Dako to find Barbara. As Tor explained his people's history to Vicki, she encouraged them in their rebellion, offering to help them. They made their way to the armoury, taking several weapons, and Tor sent Sita to help Vicki find her friends.
