Bret Vyon was a Space Security Agent who assisted the First Doctor in his quest to stop the Daleks from conquering the Solar System in 4000.


Early life[]

Bret was born in Mars Colony 16 in the late 40th century. (TV: The Daleks' Master Plan) He had three half-siblings: Sara, Lena (AUDIO: The House of Kingdom) and David Kingdom. (AUDIO: The Destroyers) In 3990, he joined the Space Security Service, making First Rank in 3995 and Second Rank in 3998. (TV: The Daleks' Master Plan) He outranked Sara, who also joined the organisation.

In 3999, Bret was stationed at the Great Clock and met an older version of Sara who was travelling with the First Doctor and Steven Taylor. As Sara was supposed to be on Venus, Bret questioned her and, when she said that she wanted to know about the Clock, he explained to her how it worked and took her to Mavic Chen to learn of its function. He congratulated her on the promotion that Chen gave her and left, perplexed by the meeting. When the Clock was destroyed later that day, he managed to escape alive and unharmed. (AUDIO: The Guardian of the Solar System)

Joining the Doctor[]


Bret Vyon (TV: The Daleks' Master Plan)

One year later, he was posted on a mission to the planet Kembel with another agent, Kert Gantry, to investigate the disappearance of fellow agent Marc Cory. Gantry was injured and he forced Bret to leave him so he could have a better chance to escape.

Almost suffering a similar fate to Marc Cory, Bret was saved when he witnessed the arrival of the First Doctor's TARDIS. He waited in the bushes until the Doctor exited to find help for an injured Steven Taylor. Bret then held the Doctor at gunpoint and forced the Doctor to give him the TARDIS key, allowing him to enter the TARDIS. He tried to force Katarina to take him off Kembel, but Steven knocked Bret out. The Doctor returned and placed Bret in a restraining chair and went outside again.

Bret managed to convince Katarina that he would not harm her and gave her two tablets which he said would help cure Steven's blood poisoning. When the tablets worked, Katarina let Bret out of the chair, and he took both of them into the jungle when he saw the Daleks on the TARDIS scanner. He investigated the jungle and saw the Daleks using their flame-throwers to burn down the jungle, after which he returned and warned the Doctor of the danger. The Doctor decided to go to the Daleks' city to find out their plans.

When they entered the city, Bret knocked out Zephon and tied him up. The Doctor donned Zephon's cloak and infiltrated the seventh meeting of the Galactic Council. Bret, Steven and Katarina hijacked the Spar, Mavic Chen's spacecraft. When Zephon sounded the alarm, Bret prepared to take off without the Doctor, but the Doctor managed to get aboard with the stolen taranium core just before they took off. Bret decided to head to Earth to warn them of the Daleks' plans. The Doctor showed him the tape-recording of Cory's SOS message which he had discovered in the jungle. From the Doctor, Bret learned that Chen had allied himself with the Daleks.

The Daleks used a remote control device to force the Spar to land on the prison planet Desperus. Bret and Steven managed to fix the damaged controls and managed to take off, but one of the convicts, Kirksen, had managed to get onboard and held Katarina captive in the airlock. Kirksen demanded they go back to Kembel or he would kill her. Despite protests from the Doctor and Steven, Bret adamantly refused to turn back. However, Katarina opened the airlock, killing herself and the convict.

Bret managed to land the Spar on Earth and took the Doctor and Steven to a research station run by his friend Daxtar. However, Daxtar gave himself away as a traitor when he mentioned the taranium, which he could not have known about unless he was told by Chen. Angry at Daxtar's betrayal, Bret shot and killed him. (TV: The Daleks' Master Plan)


Bret proposed that he could infiltrate the security service and alert the authorities himself. While they were preparing to leave, Bret's sister Sara entered. Sara, who had been convinced by Chen that Bret, the Doctor and Steven were traitors, held them all at gunpoint. However, Bret managed to cause enough of a distraction to allow the Doctor and Steven to escape but was then shot and killed by Sara. Once Sara learned the truth, she allied herself with the Doctor to save Earth and avenge Bret's death. (TV: The Daleks' Master Plan)


Bret's innocence of the treason charges made by Chen was also discovered by Senator Diksen, when the recorded warning by Marc Cory was discovered on Bret's body. Diksen subsequently had Chen's accomplice, Karlton, arrested, and dispatched a force to also arrest Chen, though by that point, Chen had already been exterminated by the Daleks. (PROSE: The Mutation of Time)

On the Space Security Service Station 7, the Eleventh Doctor told Tranter that he had worked with Bret Vyon and Sara Kingdom, prompting the station commander to comment that he had impressive credentials and must have started fighting the Daleks at a very young age. (COMIC: The Only Good Dalek)


Vyon was tall, thin and clean and was able to keep himself looking presentable even when Gantry was not. When he first met the Doctor, he needed a shave. (PROSE: Mission to the Unknown)
