The Sontarans are a fictional race of extraterrestrial humanoids principally portrayed in the British science fiction television programme Doctor Who and its spin-off series The Sarah Jane Adventures. A warrior race characterised by their ruthlessness and fearlessness of death, they were conceived by writer and future story editor Robert Holmes and first appeared in the 1973 Doctor Who serial The Time Warrior.
The Time Lords are a fictional ancient race of extraterrestrial people in the British science fiction television series Doctor Who, of which the series' main protagonist, the Doctor, is a member. Time Lords are so named for their command of time travel technology and their non-linear perception of time. Originally, they were described as a powerful and wise race from the planet Gallifrey, from which the Doctor was a renegade; details beyond this were very limited for the first decade of the series. They later became integral to many episodes and stories as their role in the universe developed. For the first eight years after the series resumed in 2005, the Time Lords were said to have been destroyed during the Last Great Time War at some point in the show's continuity between the television movie in 1996 and the show's revival. In 2013, the 50th anniversary special "The Day of the Doctor" concerned this supposed destruction and their eventual survival.
The Doctor is the protagonist of the long-running BBC science fiction television series Doctor Who. An extraterrestrial Time Lord, the Doctor travels the universe in a time travelling spaceship called the TARDIS, often with companions. Since the show's inception in 1963, the character has been portrayed by fourteen lead actors. The transition to each succeeding actor is explained within the show's narrative through the plot device of regeneration, a biological function of Time Lords that allows a change of cellular structure and appearance with recovery following a mortal injury.
The Eleventh Doctor is an incarnation of the Doctor, the protagonist of the British science fiction television series Doctor Who. He is played by Matt Smith in three series as well as five specials. As with previous incarnations of the Doctor, the character has also appeared in other Doctor Who spin-offs.
The Great Intelligence is a fictional character from the British science fiction television series Doctor Who. Although the Great Intelligence has no physical form, it is capable of communicating, both by itself and through possession, with other characters within the series. The Great Intelligence was originally created by Henry Lincoln and Mervyn Haisman and first appeared in the 1967 serial The Abominable Snowmen where it encountered the Second Doctor and his companions Jamie and Victoria. The Great Intelligence tries to form a physical body so as to conquer the Earth, making use of Yeti robots that resemble the cryptozoological creatures. Initially the Great Intelligence used the Yeti robots to scare off curiosity seekers, only later using them as an army. Both the Intelligence and the Yeti returned in its sequel The Web of Fear.
River Song is a fictional character created by Steven Moffat and played by Alex Kingston in the British science-fiction series Doctor Who. River Song was introduced to the series as an experienced future companion of series protagonist the Doctor, an alien Time Lord who travels through time in his TARDIS. Because River Song is a time traveller herself, her adventures with the Doctor occur out of synchronisation; their first meeting is with the Tenth Doctor, the Doctor's first and apparently her last. Kingston plays her in 15 episodes, as River becomes a companion, romantic interest and eventual wife of the Doctor in his eleventh incarnation portrayed by Matt Smith. From a production perspective, the Twelfth Doctor is the last incarnation to meet her, spending a 24-year-long night with her, before her first meeting with the Tenth Doctor. From the timeline perspective, the final time River meets with the Doctor, she is a hologram/echo from the library archives; she and the Eleventh Doctor part ways in the episode, "The Name of the Doctor".
