Little is known of this Doctor, for he only appears in a series of flashbacks of his next incarnation, after his memory was wiped of the 13th Doctor. He was known to be trigger happy and was running from some fairly unsavoury events at the time of the 14th Doctor's introduction in 'Trick or Treat' (2004).
