Career with UNIT Edit
After he had joined UNIT and the Third Doctor was apparently in a coma, the Brigadier summoned "Dr Sullivan" to help see him through the process. When Sergeant Benton woke the Doctor by offering him a cup of coffee, the Brigadier cancelled the call for Dr Sullivan's assistance. (TV: Planet of the Spiders)
Three weeks after confronting the Great One on the planet Metebelis III, the Doctor and his TARDIS re-appeared in his laboratory at UNIT HQ. The Doctor had received a fatal dose of radiation, forcing him to regenerate or die. (TV: Planet of the Spiders) Harry Sullivan arrived on the scene just moments after the Doctor regenerated into a new form. (TV: Robot)
Adventures with the Doctor Edit
After the defeat of the robot K1, Harry found himself in the Doctor's TARDIS. (TV:Robot) At first very much confused, he trailed the Doctor and Sarah Jane Smith to Space Station Nerva, where they were pitted against the Wirrn. (TV: The Ark in Space) Then they travelled by transmat from the space station to an uninhabited far future Earth, where they faced the Sontaran Styre. (TV: The Sontaran Experiment) Heading back to the beacon, the Time Lords intercepted the transmat beam and took them to Skaro to prevent the creation of the Daleks. (TV: Genesis of the Daleks) Via time ring, they travelled back to Nerva, but to a much earlier year. There he helped save Voga from the terror of the Cybermen. They then received a summons from the Brigadier on the space-time telegraph calling them back to 20th century Earth. (TV: Revenge of the Cybermen)
Immediately after his adventure with the Cybermen, Harry was ejected from the TARDIS and it stranded him in England, 1936. There Harry met the Eighth Doctor, who had no memory of Harry or any of his previous adventures. Harry helped the Eighth Doctor to stop a Dryad from turning the land of Britain on the people that lived upon it. The Fourth Doctor and Sarah picked Harry up shortly after. (PROSE: Wolfsbane)
Back in the late 20th century, Harry rejoined UNIT to defeat the shape-changing Zygons and their giant, dinosaur-like beast, the Skarasen, in Scotland. After the Zygons' defeat, Harry decided to return home to London by train rather than by TARDIS. (TV: Terror of the Zygons)
Sometime after the attempted Zygon invasion, Harry developed a Zygon-killing gas called Z-67 while working on captive Zygons at Porton Down. However, the gas was confiscated by the Doctor. (TV: The Zygon Invasion/The Zygon Inversion)
At some point during his UNIT career, Harry was put in charge of a team and sent to the West Country to investigate a missing UNIT team member and a subsequent series of "monster" sightings. He met up with the Ninth Doctor and his companions, Rose Tyler and Jack Harkness, and together they found the missing man and solved the mystery of the "monsters". (COMIC: Official Secrets)
Post-UNIT career Edit
By 1997, he was Deputy Director at MI5. At that time, via the agency of time travel, he met up once again with a familiar version of the Doctor, as well as a much younger Sarah Jane Smith, for whom little time had passed. (PROSE: System Shock) He still worked for MI5 in 1999, (PROSE: Millennium Shock) and became Chief of Staff at some point prior to 2015. (PROSE: Damaged Goods)
To commemorate an anniversary date, Sarah Jane had yearly meetings with Harry Sullivan. By 2006, Harry had been missing in action for some time, though Sarah kept coming to the same place they used to meet. She "talked" to him and raised a toast to him wherever he was. (AUDIO: Buried Secrets) Harry was still missing in 2009. (PROSE: The Wedding of Sarah Jane Smith)
Alternative timelines Edit
A parallel Earth version of Harry served on a nuclear submarine in a world taken over by the Silurians after the death of the Third Doctor. He saved the life of the Seventh Doctor's companion Bernice Summerfield. (PROSE: Blood Heat)
Undated events Edit
In the Hellscape Edit
A version of Harry appeared in a "hellscape" dream the Eleventh Doctor created while the mind parasite Mr Waites fed off the worst thing Doctor could imagine. In the dream, the Doctor worked with Harry at the Department of Commonality. Harry revealed that the protest at the "square" was much larger than reported and that his sister's boyfriend had proof on his camera. After the Doctor didn't enjoy working at mediation and wanted to return to records, he reported to Mr Waites about the camera, and the peace officers arrested Harry. (COMIC: John Smith and the Common Men)
Harry was rather old-fashioned and stereotypically English in his attitudes. He often employed slightly archaic language, referring to Sarah affectionately as "old girl" or "old thing" — which somewhat annoyed her. (TV: The Sontaran Experiment, PROSE: Doctor Who and the Ark in Space) He was brave, one time saving the Fourth Doctor's life from a landmine on Skaro. (TV: Genesis of the Daleks) He had a "can-do" attitude, adapting well to the many strange situations in which he found himself. He could, however, be quite clumsy and unsubtle. This led the Doctor to declare in a moment of frustration, at the top of his lungs that "Harry Sullivan is an imbecile!", before passing out from the effects of a rockfall on Voga – caused by Harry. (TV: Revenge of the Cybermen) He flirted a bit with Sarah. Despite an outward annoyance at that attitude, once when thinking him dead, Sarah admitted she found it endearing. (PROSE: Wolfsbane)
Behind the scenes Edit
- Harry has many similarities to Martha Jones: They both worked as medical officers for UNIT whilst working with other organisations, they both had adventures with the Doctor after leaving the TARDIS, both were possessed by enemies of the Doctor, and they both battled Davros, Daleks and Sontarans.
- Harry was created as a companion when it was thought that the Fourth Doctor would be played by an older actor who would not be able to handle the physical side of the series. This would necessitate Harry handling physical "two-fisted" action as the plot required. This was not a concern when the 40-year-old Tom Baker was cast in the role, as he was somewhat younger than the previous actors and capable of physical action on his own. Harry was thus deemed redundant and ultimately written out of the show, despite his popularity — a decision that Philip Hinchcliffe later admitted was probably a mistake.
- Harry is a member of a small group of companions who did not feature in any TARDIS interior scenes. Although he is seen entering and emerging from the TARDIS several times, he is never seen within the TARDIS itself.
- Following The Android Invasion, there were to be no further guest appearances for Ian Marter, as the Doctor Who production team had by this time decided to phase out UNIT and sever the Doctor's links with Earth.
- It was hoped that Marter would reprise the role of Harry for the 20th anniversary story The Five Doctors in 1983, but he had to turn down the offer, as he was committed to other work at the time.
- Although various spin-off media have depicted Harry living into the 21st century, in real life the actor who portrayed him, Ian Marter, died in October 1986. A reference to the character is made in the television story Invasion of the Bane, when Sarah Jane considers Harry as a possible name for her adopted son, Luke Smith.
- Doctor Who and the Rebel's Gamble, a story which this wiki does not consider to be a valid source, suggests that at some point Harry Sullivan shared an adventure with the Sixth Doctor.
- According to an interview in Doctor Who Magazine #512 with writer Mike Bartlett, the character of Harry in the 2017 episode TV: Knock Knock was originally to have been identified as Harry Sullivan's grandson, but the reference was cut before broadcast.
