The Shopkeeper (Lost in Time)

The Shopkeeper along with his companion, a parrot called Captain, were self-described "servants of the universe", who took more direct approaches to putting the universe in order than the Doctor. He and his parrot were capable of teleportation and opening time windows, but he was "forbidden" to travel through them himself.

Biography
On 23 November, 2010, the Shopkeeper, who refused to state his age, told the Ealing Echo that there was an alien in his shop. When Sarah Jane Smith, Clyde Langer and Rani Chandra saw the paper, they went to the Shopkeeper's shop. He revealed that it was a ploy to get them there to send them through a time window to find three pieces of Chronosteel for him throughout history to save time itself. Sarah Jane was sent to 1889, Clyde was sent to 7 June 1941, and Rani was sent to 19 May 1553. As he monitored their progress, he became increasingly anxious, noting to his parrot Captain that when the sand timer ran out they would be trapped in the past forever.

When the sands expired, he tried to close the time window but it would not shut. If left open it would destroy the entire planet. He watched as Rani and Clyde obtained their objects and returned. Sarah Jane returned empty-handed, but Angela Price, the granddaughter of Sarah Jane's companion in the past, gave her the final object and the Shopkeeper took it, and with the others closed the time window. He then bade farewell to the Bannerman Road gang, saying Captain's work was done, and he and the parrot teleported away. (TV: Lost in Time)

In 2011, he returned to drop off a baby at Sarah Jane's house. This child was initially a weapon created by Miss Myers of the Fleshkind to destroy every single Metalkind in existence. The Shopkeeper felt that the child (named Sky Smith by Sarah Jane) would be safest with Sarah Jane. When the ordeal with Miss Myers was over, he and the Captain appeared in Sarah Jane's attic to confirm it was he who dropped Sky off. He explained that it was his duty to "put things in the right places" and after Sky expressed the desire to stay with Sarah Jane, he and the Captain teleported away telling the former time-traveller she would find out exactly who he was in good time.

Behind the scenes

 * In the intended series 5 finale The Battle for Bannerman Road, the Shopkeeper would have returned, revealing that he had been manipulated by the Trickster into leaving Sky on Sarah Jane's doorstep. (The Sarah Jane Companion Volume Three)
 * The Shopkeeper was added to Sky because the original plan for Matt Smith to appear as the Doctor fell through. (The Sarah Jane Companion Volume Three)
 * When Neil Gaiman showed Russell T Davies his "Eleven Things You Probably Didn’t Know About The Corsair" page in The Brilliant Book 2012, Davies said he believed the Shopkeeper was actually the Corsair. There are similarities, as the Shopkeeper had a scarlet macaw named Captain while a dark-skinned incarnation of the Corsair was pictured with a blue-and-yellow macaw.
