The Eleventh Doctor arrived after the Tenth Doctor absorbed to much radiation. His regeneration was explosive causing the TARDIS to malfunction and career over London before crash landing in the village of Ledworth.
The first person he met was the young Amelia Pond who helped him in the hours following his regeneration by cooking him Fish Figures and Custard.
The Eleventh Doctor wears a bow-tie and has a penchant for hats.
His death was seen to take place on 22 April 2011 at Lake Silenco in UTAH, a fixed point in time, athough it later transpired he faked his death by hiding in a Teselecta.
He traveled with Amy and Rory until he was forced to leave them after they were transported by a Weeping Angel to New York in the 1930's and he saw their names on a Tombstone, creating a fixed moment in time which he was unable to break.
