Doctor Who

Doctor Who is a British Television show that's been running for over 50 years. In the show, we follow The Doctor, a time-traveling alien from the planet Gallifrey. Using his TARDIS (Time and Relative Dimensions in Space), he meets companions and whisks them away on adventure up in the stars. When the Doctor gets to old, or is dying, he regenerates, which gives him a new body. He loses part of his old personality and gains a new one made up of his adventures and experiences in the previous regeneration. The Doctor is currently on his twelfth regeneration. The fanfiction separates from the plot before/during the Christmas Special when the Doctor Regenerates into Twelve.
