Clara Oswald (Jenna Coleman)

Clara Oswald was a companion to the Eleventh and Twelfth doctors. She earned the nickname of ‘the impossible girl’ after entering the doctor’s time stream, which spit her into multiple different versions of herself, meaning she was there watching over every incarnation of the doctor. From The Shard to a submarine, Time Zombies to Trenzalore, She was there to witness it all, always by the doctor’s side.
