Margaret Blaine

Margaret Blaine was a senior member of MI5 in the early 21st century. Some time before March 2006, Blaine was murdered by Blon Fel-Fotch Passameer-Day Slitheen, who used her skin to impersonate her. (TV: Aliens of London) According to Blon, Blaine "died screaming." (AUDIO: Sync)

Still posing as Blaine, by September 2006, Blon ran for mayor of Cardiff. Shortly after, the skin suit made from the deceased Blaine was left vacant in the Doctor's TARDIS when Blon was regressed to her pre-hatched state after looking into the Heart of the TARDIS, with the egg being recovered by the Ninth Doctor. (TV: Boom Town) Later in her second life, Blon was once again in possession of Margaret's skin suit when the Twelfth Doctor encountered her. (COMIC: A Confusion of Angels)

Behind the scenes

 * Technically, Margaret Blaine never appeared in Doctor Who, only Blon Fel-Fotch Passameer-Day Slitheen masquerading as her. However, the credits for Aliens of London, World War Three and Boom Town credit the character by her alias of Margaret Blaine.
 * There is some disagreement about the age of Margaret Blaine at the time of her death. While unreadable in the episode itself, the copy of the Western Mail featured in Boom Town gives Margaret's age as 45. The reference book The Doctor: His Lives and Times, which is not considered a valid source on this wiki, includes a further Western Mail article which states that Blaine is 56.
