Seventh Doctor Originally a man with the demeanour of an eccentric , light - hearted buffoon , the Seventh Doctor darkened into a mysterious , cunning manipulator to combat Fenric ' s return . Though he delighted in humorous reverie , it was only the surface layer of his true nature . Beneath , he was a Machiavellian and somber genius of frightful calibre who could tactfully use his mind to manipulate almost any situation into reaching his favoured outcome . Despite this , every action he did " for the greater good " , as this incarnation actively sought out evil to vanquish . He could also show profound warmth and affection to his companion s , and built a strong bond with many of them . Initially , the Seventh Doctor travelled with his predecessor ' s final companion , Melanie Bush . After several adventures with the new Doctor , she left to travel with Sabalom Glitz , prompting him to begin travelling with Ace , a troubled teenager from Earth in the 1980s . Treating her both as a protégé and initially as a pawn in Fenric ' s game , he did his best to help heal Ace ' s psychological wounds by helping her come to terms with her past misdeeds and fears , aiding her in maturing and supporting her in moments of difficulty . Although he initially planned to take Ace home , they ultimately travelled together for several years , only for their strong bond to grow increasingly strained as secrets and death tore them apart . Following Ace ' s initial departure from the TARDIS , he became " champion " to the Eternal known as Time . Although he did many good deeds while under the title of Time ' s Champion , his manipulative ways and amoral decisions cost him dearly , leaving him questioning his actions and himself . The aftermath left him tired and saddened , and after reuniting with many old friends he eventually began a lonely retirement from plotting . Though wearisome , he decided he would return to Gallifrey when the Time Lord s needed his assistance , but having grown complacent in his retirement , he let his guard down at the wrong time , and paid for it with his life . After many years of schemes and manipulation , the Seventh Doctor regenerated in San Francisco on 31 December 1999 , following Dr Grace Holloway ' s exploratory surgery on his gunshot wounds accidentally clogging a vein . Biography . A day to come . The First Doctor was shown footage of the Seventh Doctor , as well as his ten other successors , by the Testimony when he expressed doubt over the Twelfth Doctor ' s identity . ( TV : " Twice Upon a Time " ) When the Fifth Doctor was under the influence of the Dark , he saw a nightmare image of himself regenerating into his seventh incarnation on a blood soaked altar . ( PROSE : " Fear of the Dark " ) Mawdryn attempted to force the Fifth Doctor to use up his eight remaining regenerations to end his follower ' s cycle of perpetual rebirth , but this was rendered unnecessary when Alistair Gordon Lethbridge - Stewart made physical contact with his younger self and a discharge of temporal energy was released that allowed Mawdryn and his followers to die . ( TV : " Mawdryn Undead " ) The Seventh Doctor was described as " the schemer " by the Doctor ' s first TARDIS to the Fifth Doctor . ( AUDIO : " Prisoners of Fate " ) After the TARDIS became " stalled in the equivalent of a galactic lay - by " , the Sixth Doctor had a worried thought of Peri Brown growing old and dying in the TARDIS , while he would " go on regenerating until all [ his ] lives [ were ] spent . " ( TV : " Vengeance on Varos " ) When exposed the Valeyard ' s alliance with High Council to the Sixth Doctor at his trial , he revealed that the Valeyard was acting as the prosecutor for the trial in exchange for the Doctor ' s remaining regeneration s . ( TV : " The Ultimate Foe " ) The Valeyard offered to tell the Sixth Doctor of his next incarnation , whom he claimed was filled with " plots and schemes , " all to win a game " that was never his to win . " ( AUDIO : " Trial of the Valeyard " ) When she met him out of sequence , the Rani told the Sixth Doctor that she was expecting " the little man with the hat and the umbrella " , only for the Doctor to interrupt her before he could hear more about his future self . ( AUDIO : " The Rani Elite " ) Post - regeneration . According to one account , the Sixth Doctor , after being sapped of chronon energy whilst fighting the Lamprey , ( PROSE : " Spiral Scratch " ) suffered a fatal head injury ( AUDIO : " Zagreus " ) due to the buffeting of the TARDIS caused by the Rani ' s laser bombardment . ( TV : " Time and the Rani " ) A second account showed that the Sixth Doctor was sent a psychic signal advising him to go to the planet Lakertya , despite an ominous source of radiation being nearby . Upon approaching Lakertya , the TARDIS came under attack from focused beams of the radiation being fired from the Rani ' s TARDIS . Whilst Mel only passed out , the Doctor was mortally wounded by the radiation . As the persona of the Seventh Doctor manifested before him , the Doctor ' s sixth persona dissolved into his seventh , both agreeing their future was " in safe hands . " ( AUDIO : " The Brink of Death " ) After the laser attack , the TARDIS was caught in the Rani ' s tractor beam , and forced to make a landing on Lakertya ' s surface , where the Rani and her Tetrap servant , Urak , boarded the TARDIS and abducted the Doctor as his regeneration concluded , taking him to the Rani ' s laboratory . Awakening in the Rani ' s lab , the Doctor immediately recognised her , but was knocked out by Urak and injected with an amnesia - inducing drug , which allowed the Rani to trick him into assisting her with her project by pretending to be Mel . Upon regaining consciousness again , the partially amnesiac Doctor first decided to choose a new look , before returning to work on the Rani ' s machine , having been convinced by " Mel " that he had been working on it before an accident caused him to regenerate . However , as the Doctor found what was wrong with it , the real Mel snuck into the lab and the two convinced each other of their identities , exposing the Rani ' s lies . Escaping , the Doctor discovered that several other geniuses from throughout time , including Albert Einstein and Hypatia had been captured to act as components of the Rani ' s " time brain " . Forced to become the final component , the Doctor ' s still recovering mind caused it to spout nonsense , though he also inadvertently provided the brain with the means to determine the needed substance : Loyhargil . The Lakertyan leader , Beyus , then sacrificed his life to destroy the brain and delay the launch long enough for the rocket to miss the asteroid . Rescuing the captives , the Doctor took them back to their own times . ( TV : " Time and the Rani " ) Bemoaning the loss his umbrella and scarf , the Doctor went back to his wardrobe and obtained a new paisley scarf and whangee - handled umbrella . Taking the time to clean out the dimensionally transcendental pockets of his former self ' s patchwork coat , he sat down to sort the contents of several lifetimes , organising them into two piles , of what was useful and what was not . While doing so , he considered the consequences of regeneration , and assessed whether he was going to like his new body . ( PROSE : " The Useful Pile " ) Travels with Mel . Shortly after he dropped Mel off in London , the Doctor became a prisoner at " the Institute " , and sent the TARDIS back to Mel to save him . After he had been driven insane , the Doctor was found by Mel , who helped him restore his mind and sanity . Informed that the institute was run by the Celestial Intervention Agency , the Doctor found that medics were conducting experiments to graft TARDIS minds into sentient life forms , and , horrified at their amoral stance , restored the TARDIS consciousnesses to their physical bodies , and freed the inmates . ( AUDIO : " Unregenerate ! " ) The Doctor took Mel to Sussex Downs in 2040 to show her how much human computer technology had advanced from her time . They found a community of mathematicians led by Thea , who believed that they had discovered the pattern of the TARDIS ' s landings on Earth and could thus predict the time and place of their arrivals . The Doctor tried to explain that it was just chance , but Thea refused to believe him . Determined to prove them wrong , the Doctor took the TARDIS back in time five weeks , thus spoiling the pattern . ( PROSE : " Daisy Chain " ) Visiting the Hammerson Plastic PLC New Year ' s Eve 1999 gala , the Doctor revealed to Mel that its owner , Alisha Hammerson , was in fact an advanced Auton under the control of the Nestene Consciousness . After her Autom workers gassed the building , the Doctor was awoken by Hammerson , and given a tour of the building .

( COMIC : " Plastic Millenium " ) On a visit to Croydon on 24 December 1995 , Mel and the TARDIS disappeared . Investigating , the Doctor found an archaeological dig and met archaeologist Michael Gregson , who told him the history of unusual phenomena attached to the site .

( PROSE : " 24 Crawford Street " ) Travelling to Paradise Towers so Mel could enjoy its swimming pool , the Doctor found that the staff and residents residing within the Towers had all become either anarchist Kang s , cannibalistic Rezzie s or pompous Caretakers .

The real architect , Kroagnon , a madman who killed anyone who moved into his creations to keep them perfect , was still within the complex , and had been using the Cleaner s to murder residents . As the Doctor and Mel investigated , Kroagnon became concerned , and transplanted his disembodied mind into the Chief , going on a murderous rampage through the complex . He was defeated when Pex , the only remaining male resident , pushed him to his death down a lift shaft , sacrificing himself to prove his bravery . ( TV : " Paradise Towers " ) The Doctor and Mel then travelled to Pax Lucis , an English village occupied by Nazi s during the Second World War .

The Doctor gained an ally in the Nazis ' commander , Luther , who sacrificed himself by blowing up " the weapon " , saving the planet . ( PROSE : " Special Weapons " ) When the TARDIS was forced to materialise in England in 1978 , the Doctor and Mel traced the cause to an anomalous concentration of artron energy from a Cnidarian artefact discovered in a cave by a group of university students .

( PROSE : " The Invertebrates of Doom " ) The Doctor and Mel foiled a Vardan invasion of Earth with Nikola Tesla and encountered weretarantula s on Vyga 3 .

After the planet was named Prosper , the Doctor proposed to Mel that they take a holiday to Earth . ( AUDIO : " Maker of Demons " ) In search of leptonite crystal s to combat the Quark s on the space yacht " Pinto " , the Doctor and Mel arrived on the planet Puxatornee in the year 3090 , where the inhabitants were struggling to live in peace with a race called the Slithergee s , who were slowly taking over after they arrived there as refugees 30 years prior . The Doctor and Mel were forced by two inhabitants , Stuart and Reed , to travel back to 3060 to kill the president of Puxatornee before she could invite the Slithergees to stay . When they returned from the successful assassination , history had changed so that the Slithergees instead went to war with the Puxatornees . The Doctor and Mel became separated with Stuart and Reed and captured , but realised that an alternative Mel and Doctor were due to land in the same place as them and quickly escaped back to their TARDIS and left . The other Doctor and Mel successfully landed on Puxatornee , and were captured and interrogated by the new history ' s Lt . Stuart and Reed before the old history ' s Reed and Stuart arrived to help them escape , but were killed shortly afterwards . The new history ' s Stuart and Reed then forced the Doctor and Mel to take them back 30 years so that they could prevent the president ' s death and make peace with Slithergees . The Doctor and Mel took them back to 3060 to see their new history , which was the first version before he and Mel showed up . Lt Stuart and Reed then ordered the Doctor to take them back to the previous day to prevent their earlier selves from time travelling , but the Doctor couldn ' t as that history no longer existed . The Doctor worked out that an alternative version of himself and Mel were due to land any minute and took off in the TARDIS just as their earlier selves showed up . ( AUDIO : " Flip - Flop " ) Arriving in Britain in 1987 , the Doctor and Mel were shocked to see a tower in the exact form of a Dalek , serving as the main office of the Zenos Corporation . As Mel infiltrated the Zenos Corporation , the Doctor learned that the Daleks were working with the corporation ' s CEO , Alek Zenos , to present themselves to the British government as interested in becoming Britain ' s economic partners in the galactic market . As part of this plan , the Daleks also introduced a new video game , " Warfleet " , which allegedly depicted a space empire pursuing a rebel ship , but actually allowed the players to take control of Dalek drone ships in the future and use them against the Daleks ' enemies , subverting the Daleks ' usual handicap of relying on pure logic . The Doctor nearly turned the tables when Mel was able to tell the Warfleet players what was happening and convince them to help the rebels , as well as the revelation that Alek Zenos was actually a double agent working with Thal rebels against the Daleks . However , things turned against the Doctor when MP Celia Dunthorpe allied with the Daleks , believing that the economic benefits of an alliance with the Daleks were more important that the Doctor ' s warning about how dangerous they were . Although the Daleks almost won by using the Zenos Tower to transmit a Dalek perspective across London , brainwashing even Mel to adhere to a Dalek philosophy , the Doctor was able to cure Mel of the programming and pass on instructions before he was taken to Skaro for trial . Using the Doctor ' s advice , Mel was able to reprogram the time corridor in Zenos Tower to send the entire tower to Skaro , the continued broadcast of the ' Dalek Factor ' causing all Daleks on Skaro to turn on each other as their natural aggression and arrogance was amplified . With the Daleks destroying themselves and the " Warfleet " players helping the rebels rescue the Thal slaves on Skaro , the Doctor used the building to trigger a time storm after setting up a time corridor to take himself and his allies back to Earth , the resulting storm causing most Daleks left on the planet to age to death as their parts became too old to operate . ( AUDIO " We Are The Daleks " ) Responding to a distress call , the Doctor and Mel found themselves in an abandoned human mining colony that had been re - appropriated as a Sontaran research base , only for the Sontaran research team assigned there to have gone insane , most of them now dead and the surviving commander now a gibbering wreck hiding in the cells under a blanket made from his former uniform . When a new Sontaran force was sent to investigate , the Doctor realised that the cause of the mental imbalance was the telepathic influence of a silicon - based life - form in the base ' s former mines , which identified itself as ' The Bloom ' , absorbing the emotions of the residents of the facility to allow itself to grow . While the original miners had only been affected by the Bloom after prolonged exposure to it , the Sontarans ' experiments at influencing human emotions had given the Bloom far more emotional material to ' feed ' on , driving the Sontarans and the former prisoners to increasingly irrational actions , such as Sontarans fighting each other in the dark in a brief panic and one of the prisoners trying to break a glass observation dome despite the planet ' s tainted atmosphere . As a result of this emotional ' stimuli ' , the Bloom had achieved sentience at the cost of making it far more hostile due to the Sontarans ' violent nature , now manifesting as a dust cloud that consumed the humans and Sontarans to gain their knowledge and experience . Despite acknowledging the Bloom as a sentient creature with a right to exist , The Doctor refused to let it continue in its current state due to the danger it posed to others , tricking the last Sontaran present into carrying bombs directly into the Bloom while he , Mel and the remaining human survivors retreated to the TARDIS , the Doctor hopeful that the explosion would disperse the Bloom to such an extent that it would have to start its ' evolution ' over again and hopefully become something more peaceful .

When the burned Master took the Doctor prisoner and confronted his other self , the Doctor realised that the two Masters were somehow in each other ' s bodies . With this discovery , coupled with the Masters referencing prior encounters with his immediate two previous incarnations that he couldn ' t remember , the Doctor deduced that the two Masters were responsible for the previously - detected gaps in reality due to their current paradoxical state . Although the Doctor was able to convince them not to compound the paradox by trying to send the younger Master into " his " body , the two Masters , once restored to their own bodies , stole the Doctor ' s TARDIS and fled the currently - crashing ship , mockingly informing the Doctor that Jemima had already been killed . However , the Doctor was able to take refuge in an energy - seeking missile and flee the destruction of the ship , using the missile to find the Master ' s TARDIS and then track the two Masters to the only part of reality left intact as reality collapsed .

Before the Masters could kill the Doctor or remake the universe , the Doctor was able to knock them down using the sonic emitter , subsequently using the Cult ' s equipment to remake the universe as it had been before , his own two changes being to send the two Masters back to wherever they had been before they made contact with the Cult and to restore Jemima to a life where she had never been captured by the Rocket Men in the first place .

He managed to make Klein follow him from a pub into his TARDIS , unintentionally with junior science officer Will Arrowsmith in tow . Travelling to Düsseldorf in 1945 , they met Lukas Hinterberger , a Nazi who claimed to be one of Schalk ' s colleague , who apparently recognised Klein and immediately opened up to her , raising suspicion from Klein and the Doctor . Hinterberger told them about beings called the Struwwelpeter , and eventually agreed to take them to Schalk . Arriving on the Greek island of Minos , they came face to face with the Struwwelpeter , godlike beings from another universe whose true names were the Shepherd and Shepherdess . Considering this universe to be evil and decadent , they gave Schalk the knowledge to build a device known as the persuasion machine so that they could manipulate all beings in the universe to submit to their will . The Doctor trapped them on New Peerlessness , a prison planet near Kasterborous , but was unable to prevent the Klecht entity from taking Schalk , forcing the TARDIS crew to search for him . ( AUDIO : " Persuasion " ) The Doctor found a weapons auction intergalactic commercial being presented by Garundel , and realised Garundel was auctioning Schalk alongside a prototype of the persuasion machine .

Using the prototype of the machine to persuade Garundel and Ziv to rescue Klein , the Doctor explained to Will that the body they had found was actually that of Hinterberger ; Schalk had used the machine to convince Hinterberger he was Schalk and then used it on himself to convince himself that he was Hinterberger .

After getting an audience with a Dalek clone of Schalk , the Doctor and Klein concluded that the Daleks were still hidden on Azimuth . The Doctor revealed to Klein that there was a blood connection between her and Schalk , prompting her to ask him to take her to 1945 to discover the truth , just as Will returned and told them about a man called " Father " that wanted a meeting with the Doctor . Going to the meeting alone , the Doctor discovered that Father was actually Davros , and the two were taken to the Daleks and Schalk , enabling the Doctor to deduce that Klein had travelled in the TARDIS to three weeks before they first arrived in Düsseldorf , discovered that Schalk was her biological father , and that she was engineered to operate the persuasion machine . At that moment , Klein returned in the TARDIS and , having seemingly reverted to her original counterpart , claimed to be willing to become the tool for the persuasion machine . A man called Falkus then entered the room and , revealing himself as Davros ' s " son " , ordered the Daleks to exterminate Schalk , but Klein forced the Daleks and Falkus to die with the power of the machine . Will returned with the Shepherd , who threatened to kill them all , but Klein used the power of the machine to kill the Shepherd , dying in the process . After ensuring that Davros ' escape pod would land on Lemuria , the Doctor and Will noticed that the Klein who had just died was actually her mother , prompting them to search for Klein on 1945 Earth .

Before falling unconscious , the Doctor saw the Master exiting the TARDIS in liquid form , and tried to warn a survivor of the shootout who came to his aid , Chang Lee , to stop him , but Lee could make no sense of the Doctor ' s warning . Lee hailed an ambulance , and the Doctor was taken to Walker General Hospital , where the bullets were found to have caused only minor injuries and removed . However , the medical team assumed that he was fibrillating and that the X - ray s showing his two hearts were a double exposure , and Cardiologist Doctor Grace Holloway was called to undertake exploratory surgery to " fix " his abnormal heartbeat . The Doctor woke up just as Holloway began the surgery , and tried to stop her operating on him by explaining his non - terrestrial origins , but Holloway and the surgeons believed him to be acting irrational due to the pain and quickly put him under anaesthetic . Shaking off the effects to give one last warning about the Master , the Doctor was rendered unconsciousness . Holloway rapidly became lost in the Doctor ' s cardiovascular system , and he began to flatline when she damaged his circulatory system with her probe . Though the team attempted to revive him , their attempts only allowed to Doctor to awaken briefly , and he was pronounced dead after he let out a final scream . Unlike his previous deaths , this regeneration did not begin promptly ; his successor attributed his delayed regeneration to having been under anaesthesia at the time . The hospital staff locked the Doctor ' s dead body inside a cold chamber , with a " John Doe " toe tag attached and a sheet placed over his body .

Though he attempted to contact the Time Lords , the Doctor was unable to as his TARDIS began to explode .

Afterwards , the First Doctor turned off the automatic distress actions which had brought all of the Doctors to the pocket dimension , triggering the TARDIS ' destruction , making it so none of it had happened . ( AUDIO : " The Light at the End " ) In an alternative timeline , the Doctor was able to save Jan Rydd and his fellow Travellers on Heaven in 2570 , and , in yet another alternative timeline , was beheaded by an Ice Warrior on Peladon in 3985 .

( PROSE : " Infinite Requiem " ) However , as he matured , he became a grumpy and melancholy manipulator who saw the battle between good and evil as a game of chess or a stage play , and everyone around him as pawns in the game of fighting evil that he directed , ( TV : " Remembrance of the Daleks " , " Silver Nemesis " , " The Curse of Fenric " ; PROSE : " " , " The Highest Science " , " Head Games " ) though he hated himself for it , ( PROSE : " Iceberg " , " Blood Heat " ) instead desiring a life of playing the spoons and acting as a children ' s entertainer with his magic tricks .

( AUDIO : " Project Lazarus " ) The Doctor would claim that he served as Time ' s Champion because of " principles , truth , love and harmony , peace and goodwill , [ and ] the best of intentions . " ( PROSE : " Return of the Living Dad " ) Despite viewing himself as " a nice little man in a silly jumper " , ( AUDIO : " Harvest of the Sycorax " ) he was viewed as being the most dangerous of the Doctors by UNIT , ( AUDIO : " Persuasion " ) and would often only see the " bigger picture " rather than the world before him , ( PROSE : " Head Games " ) which resulted in him causing much grief , such as devastating Ace by labelling her an " emotional cripple " to weaken Fenric ' s power by making her abandon her belief in him .

( AUDIO : " The High Price of Parking " ) Ace , considering the Doctor to be her " guru " , ( AUDIO : " Nightshade " ) believed that he had the " deepest , saddest eyes " , ( AUDIO : " The Prisoner ' s Dilemma " ) and even told him that she loved him .

( AUDIO : " Persuasion " ) However , after being saved from one of the Eight Legs by the Eighth Doctor , he became determined to enjoy every minute of his current incarnation .

( PROSE : " The Eight Doctors " ) He " [ couldn ' t ] stand " burned toast , loathed bus stations , calling them " terrible places full of lost luggage and lost souls " , and hated unrequited love , tyranny , cruelty , ( TV : " Ghost Light " ) the taste of pear s , ( PROSE : " Human Nature " ) swimming , ( PROSE : " The Also People " ) and goodbyes . ( PROSE : " The Room With No Doors " ) He also had little respect for those who chose not to fight injustice when they had the power to .

( AUDIO : " Thin Ice " ) He also told Benny Summerfield that he loved " chaos , big explosions , and rebellions " , ( PROSE : " Love and War " ) described E flat minor as his favourite musical key , gave blue as his favourite colour , ( PROSE : " Lucifer Rising " ) and claimed having his hair cut relaxed him more than anything . ( PROSE : " The Left - Handed Hummingbird " ) He also enjoyed playing nine dimensional scrabble , ( PROSE : " St Anthony ' s Fire " ) drinking lemonade , ( PROSE : " Just War " ) and " doing interviews " . ( PROSE : " Happy Endings " ) When thinking about rewards he could seek for his actions , the Doctor thought about " the smile of a baby child , the first sunset on a soft and new - born world , [ and ] the taste of the purest spring water , untouched by any pollution of Man ' s making . " ( PROSE : " The Dimension Riders " ) According to Ace , while the Doctor " wasn ' t scared of monsters or pain or dying , he was scared of being alone , " ( PROSE : " The Left - Handed Hummingbird " ) though he would decide later in life to travel alone after a devastating incident made him realise that he couldn ' t trust himself with anyone ' s life . ( AUDIO : " The Resurrection of Mars " ) He also admitted to the Mi ' en Kalarash that he was afraid of the Old Time , the Times of Night and Chaos . ( AUDIO : " House of Blue Fire " ) While his human counterpart fell in love with Joan Redfern , ( PROSE : " Human Nature " ) the Doctor himself was decidedly celibate , ( AUDIO : " Bang - Bang - a - Boom ! " ) failing to understand human attraction and affection , ( PROSE : " " ) except when it came to Ace . ( PROSE : " " ) He could also be critical of human nature , stating that humans had " the most amazing capacity for self - deception , matched only by [ their ] ingenuity when trying to destroy [ themselves ] " , ( TV : " Remembrance of the Daleks " ) that " among all the varied wonders of the universe , [ there was ] nothing so firmly clamped shut as the military mind " , ( TV : " Battlefield " ) and that their expectation that " everything [ had ] to be within [ their ] comprehension " was their " most irksome trait . " ( PROSE : " The Dimension Riders " ) However , he admitted to Mikey that , despite their illogical behaviour , he found human beings irresistible . ( PROSE : " Bad Therapy " ) In direct contrast to his previous incarnation , the Seventh Doctor was opposed to violence of any sort , although he proved capable of rendering an opponent unconscious with a touch ( TV : " Battlefield " , " Survival " ) by using the Venusian nerve pinch . ( PROSE : " " ) While he was completely against the use of firearms , ( TV : " The Happiness Patrol " ) the Doctor was willing to use a Tissue Compression Eliminator to defend himself against Death ' s Head . ( COMIC : " The Crossroads of Time " ) Believing " killing [ to be ] wrong except when it ' s right " , ( PROSE : " Original Sin " ) the Doctor was not averse to manipulating events that resulted in the lose of life , ( PROSE : " Love and War " ) taking a life by himself , or convincing someone to commit suicide , ( PROSE : " Zamper " , " Just War " , " Loving the Alien " , " Utopia " ) though he refused to shoot when it served no purpose . ( PROSE : " First Frontier " ) He also played a part in the destruction of many planets , such as Skaro , ( TV : " Remembrance of the Daleks " ) the Seven Planets , ( PROSE : " The Pit " ) and the Silurian Earth . ( PROSE : " Blood Heat " ) The Seventh Doctor believed evil to be a genuine force , ( PROSE : " Strange England " ) considered pacifism to be a " noble ideal " , ( AUDIO : " Fiesta of the Damned " ) and also maintained a strict vegetarian diet . ( PROSE : " Human Nature " , " Happy Endings " , " Return of the Living Dad " , " The Room With No Doors " , " Lungbarrow " ) He took five to six sugars in his tea , ( AUDIO : " House of Blue Fire " ) with his favourite teas being Arcturan , Earl Grey and Lapsang souchong , ( PROSE : " Lucifer Rising " ) his favourite ice cream being boysenberry ripple , ( PROSE : " The Left - Handed Hummingbird " ) and his favourite biscuits being chocolate HobNob s . ( PROSE : " Cold Fusion " ) While he didn ' t like peppermint tea , he drank some when it was a gift from a friend . ( PROSE : " Notre Dame du Temps " ) While he was of the opinion that his third and fourth incarnations were not unattractive , ( PROSE : " The Algebra of Ice " ) he regretfully felt that his fourth incarnation had " condemned untold billions to death by not destroying the Daleks at the moment of their birth " , and resented that his fifth incarnation " could have saved billions more by shooting down Davros like a mad dog when [ he ] had the chance " . ( PROSE : " Lucifer Rising " ) The Seventh Doctor was generally disliked by his other incarnations . ( AUDIO : " The Shadow of the Scourge " ) The Fifth Doctor was repulsed by his manipulative nature , ( PROSE : " Cold Fusion " ) and the Sixth Doctor told Evelyn Smythe that his successor was " always blowing up planets " , something he was " not looking forward to " . ( AUDIO : " The 100 Days of the Doctor " ) The Eleventh Doctor described his seventh incarnation as " probably one of [ his ] more circumspect periods . " ( AUDIO : " Shockwave " ) The Eighth Doctor came to view his immediate predecessor ' s manipulative nature with disdain , telling Lucie Miller that he was always " the man with the master plan , " arranging the destruction of his enemies and the toppling of dictatorships in order to serve the greater good , to the point where he began to countenance sacrificing the lives of the few to save the many . In this regard , he negatively compared him to the Monk . ( AUDIO : " The Resurrection of Mars " ) Ace had twice described the Doctor as an " aging hippy " , once during their early travels ( TV : " The Greatest Show in the Galaxy " ) and again during their battle with the Monk , ( PROSE : " No Future " ) with the Doctor later agreeing with the sentiment during their last adventure together . ( PROSE : " Set Piece " ) Guy de Carnac , however , compared the Doctor to an owl , observing that " he [ was ] comfortable in the darkness " , and also though the Doctor " [ was ] equally as adept at hunting down prey in cold blood " . ( PROSE : " Sanctuary " ) Fakrid believed the Doctor had " the mind of a genius " , but he also " prattle [ d ] like any other parasite " . ( PROSE : " The Highest Science " ) Dr Smith , who initially saw the Doctor as a " great scientist " , quickly changed her opinion of him to that of " an entertainer who might be hired for a children ' s party " after the Doctor started enthusiastically rambling . ( PROSE : " Zamper " ) Iris Wildthyme described the Doctor as " a portentous little feller , swaggering around , thinking he ' s got all the world ' s darkest secrets under his hat . " ( PROSE : " The Scarlet Empress " ) Brigadier General Adrienne Kramer described him as " a manipulative little weirdo who was always up to something behind [ her ] back . " ( PROSE : " Vampire Science " ) When she encountered the Seventh Doctor shortly before her death , Evelyn Smythe criticised him for his scheming , manipulative nature , ( AUDIO : " A Death in the Family " ) while Melanie Bush described the man he became as " a liar and a user and quite possibly a murderer " , and proclaimed that she wanted nothing more to do with him . ( PROSE : " Head Games " ) The Doctor associated regeneration with death , calling it a " miniature death " . ( PROSE : " The Room With No Doors " ) Though he was afraid of it , ( PROSE : " Parasite " ) the Doctor wished to die alone , ( PROSE : " Transit " ) on his own terms , ( PROSE : " The Room With No Doors " ) and also believed it would be best if all traces of him were erased . ( PROSE : " Transit " ) While the Doctor originally thought he would " beat chance and choose the moment to die " , he later confessed to Benny that he knew he would die " [ without ] control , surrounded by strangers , [ and ] helpless . " ( PROSE : " Return of the Living Dad " ) He later told Chris Cwej that he viewed regenerating as both a good and bad feeling in the same way that driving a car very fast was a good and bad feeling ; enjoying the exhilaration of the process but knowing that you were going to " die " at the end . ( PROSE : " The Room With No Doors " ) After getting shot in a gang shootout in San Francisco , the Doctor spent his last lucid moments desperately trying to warn Dr Grace Holloway not to operate on him , proclaiming his need to stop and , after succumbing to sedation , screaming in agony when the operation dealt fatal damage to him . ( TV : " Doctor Who " ) Holloway noted that the Doctor seemed " very clear , very determined and very powerful " while also looking " very serious but also very frightened of something " , and felt that he was " rarely afraid of anything " . ( PROSE : " The Novel of the Film " ) The Doctor later recalled his demise as being " undignified " , and expressed annoyance that he " [ hadn ' t seen ] that one coming " . ( AUDIO : " Zagreus " ) Habits and quirks . Speaking with a Scottish accent , ( TV : " Time and the Rani " ) that was noted by Bernice Summerfield to be of the Highlands , ( PROSE : " Big Bang Generation " ) the Seventh Doctor occasionally rolled his ' R ' s and emphasised his ' P ' s and ' L ' s . ( TV : " Paradise Towers " , " Delta and the Bannermen " , " The Greatest Show in the Galaxy " ) He could , when necessary , adopted other accents , though . ( PROSE : " The Highest Science " , " No Future " , " Bad Therapy " , " The Room With No Doors " ) When talking about Dalek s , the Doctor ' s voice would develop a harder edge to it . ( PROSE : " Illegal Alien " ) The Doctor occasionally displayed a tendency to mangle and combine Earth idioms , creating s . ( TV : " Time and the Rani " , " Delta and the Bannermen " ) After Mel described the habit as " really annoying " , the Doctor promised that he would try to stop doing it , ( AUDIO : " Bang - Bang - a - Boom ! " ) though would later slip up on his promise long after she had left the TARDIS . ( PROSE : " White Darkness " , " No Future " , " Sanctuary " , " The Also People " ) The Doctor would routinely answer any query as to his health with a biffed back claim to be " fine " , and often told others that " monsters " feared him in their " nightmares " . ( PROSE : " Love and War " , " Blood Heat " , " Continuity Errors " , " Return of the Living Dad " ; AUDIO : " The Shadow of the Scourge " ) The Doctor was fond of using the term " grubby " when explaining his mission to keep an artefact away from his adversaries , such as when keeping the Hand of Omega out of the Daleks ' " grubby little protruberances " , ( TV : " Remembrance of the Daleks " ) when he sent the TARDIS away to keep the Robot Ant s from getting their " grubby little mandibles " on it , ( PROSE : " Set Piece " ) and when preventing the fake skull of Jesus Christ from falling into Louis de Citeaux and Francisco Guzman ' s " grubby little protruberances " . ( PROSE : " Sanctuary " ) The Doctor would often raise his hat to greet new people , smiling as he did so , ( PROSE : " Lungbarrow " ) or when he was departing from company . ( TV : " Paradise Towers " ) As a show of affection , the Doctor would gently press his forehead against a friend ' s forehead , ( TV : " Time and the Rani " ; PROSE : " Sleepy " ) or tap their nose . ( TV : " The Greatest Show in the Galaxy " , " The Curse of Fenric " ; PROSE : " Bad Therapy " ) Skills . The Seventh Doctor was a grand manipulator , often utilising his choice of words to persuade others into a decision of his choosing , ( TV : " Paradise Towers " , " The Happiness Patrol " ) or devising an unscrupulous scheme to defeat his adversaries . ( TV : " Remembrance of the Daleks " , " The Curse of Fenric " ) He had a tendency to play the long game in his schemes , preferring to keep his plans subtle and " behind the scenes " . ( PROSE : " " , " The Highest Science " ) When his plans went awry , or an unexpected element developed , the Doctor was efficient at improvising around it . ( TV : " Remembrance of the Daleks " ) However , as he got older , his power of persuasion weakened , with the Doctor unable to convince Grace Holloway not to operate on him . ( TV : " Doctor Who " ) The Doctor could calm a person , ( PROSE : " Blood Heat " , " Legacy " , " Head Games " ) erase their memories , ( PROSE : " No Future " ) or induce someone to sleep by touching their forehead , ( PROSE : " GodEngine " ) and also read a person ' s dreams with a touch to the head . ( PROSE : " Sleepy " ) However , he could also influence people ' s decisions without the need for physical contact , such as when making Mel leave with Sabalom Glitz . ( PROSE : " Head Games " ) He was also able to set up a psychological block in Sally Morgan ' s limbic system by touching her forehead . ( AUDIO : " House of Blue Fire " ) Despite his stature , the Doctor was capable of both directly and indirectly taking control of situations involving strangers , using his greater intelligence to assess and direct events . ( TV : " Remembrance of the Daleks " , " The Happiness Patrol " ) While he loathed violence , the Doctor also showed a skill at unarmed combat , being able to briefly overpower a judo trained Mel , ( TV : " Time and the Rani " ) a Cheetah virus infected Master , ( TV : " Survival " ) strike down two Hitler Youth s with a series of slaps , ( PROSE : " " ) and disarmed Aoi using martial arts . ( PROSE : " The Room With No Doors " ) Something of a showman , the Doctor was an adept physical performer , and deployed a repertoire of magic tricks , illusions and escape artistry as part of his plans . ( TV : " The Greatest Show in the Galaxy " ) He could juggle five balls with his feet whilst stand on his head and gargling " The Star - Spangled Banner " ( PROSE : " Lucifer Rising " ) and whistled " anything you can do , I can do better " while a small bomb was in his mouth , ( PROSE : " The Also People " ) but he could not dance . ( PROSE : " Bad Therapy " ) He could also perfectly mimic the local fauna of his surroundings , ( TV : " Silver Nemesis " ) such as a lion ' s roar . ( PROSE : " Iceberg " ) He was also capable of picking a lock with a hairpin . ( PROSE : " The Death of Art " ) The Doctor also showed a knack for playing the spoons as a musical instrument , ( TV : " Time and the Rani " , " The Greatest Show in the Galaxy " ; PROSE : " " , " Conundrum " , " Strange England " , " The Ghost ' s Story " ; AUDIO : " Colditz " , " Afterlife " ) though this was done less as he matured . ( AUDIO : " Master " ) Representing Earth in lieu of Nicky Newman , he won the 309th Intergalactic Song Contest by playing the spoons , ( AUDIO : " Bang - Bang - a - Boom ! " ) and also broke the galactic record for continuous spoon - playing , with sixty - seven hours to his name . ( PROSE : " The Also People " ) He could also play the piano . ( PROSE : " Blood Harvest " ) Claiming to be " fluent in everything " , ( PROSE : " " ) the Doctor could speak the ancient dialect of the Japanese royal family , ( PROSE : " Transit " ) read the writing of the Silurian s , ( PROSE : " White Darkness " ) swear in Old Low Gallifreyan , ( PROSE : " Blood Harvest " ) knew sign language , ( PROSE : " Sleepy " ) use his eyebrows to communicate with Benny , ( PROSE : " The Trials of Tara " ) and , without the aide of the TARDIS ' s translation circuit , could speak German , ( PROSE : " " ) French , ( PROSE : " Set Piece " ) ancient Betelgeusian , ( PROSE : " The Death of Art " ) plain Anglo - Saxon , ( PROSE : " Damaged Goods " ) and Draconian . ( PROSE : " Monitor " ) The Doctor could levitate off the ground whilst in meditation ( PROSE : " Lucifer Rising " ) deliberately lower his intelligence , ( PROSE : " Parasite " ) identify blood samples by taste , ( PROSE : " Bad Therapy " ) pilot a helicopter , ( PROSE : " Eternity Weeps " ) and crack a safe by listening to the turns of its dial . ( AUDIO : " Lurkers at Sunlight ' s Edge " ) The Doctor was also an admired chief , able to work as a cook on the " Schirron Dream " , ( PROSE : " Sky Pirates ! " ) with Ace saying he made " great omelette s " . ( AUDIO : " The Fearmonger " ) He also knew how to make sofrit page s and could mix a good sangria . ( AUDIO : " The Rapture " ) The Doctor ' s sense of smell was sensitive enough for him to differentiate between ketones , ammonia , amino acids , aldehydes , butyric acid and geosmin in cheese , though he could choose to switch off the part of his brain that identified the chemicals if he so chose to enjoy the taste of the cheese . ( PROSE : " Culture War " ) With a thought process that worked faster than his mouth , ( PROSE : " The Also People " ) the Doctor could memorise entire files after flicking through them , ( PROSE : " Blood Harvest " , " Bad Therapy " ) and was capable of mentally keeping up with a ship that thought picoseconds was a long time . ( PROSE : " The Also People " ) After opening a surgery in the alternate universe TARDIS , the Doctor was able to remove genetic implants from soldiers modified by the Skrak , and sew Sareth ' s hand back on to him while doing so . ( PROSE : " Death and Diplomacy " ) Appearance . The Seventh Doctor was a short man , who initially appeared to be in his mid - forties , ( TV : " Time and the Rani " ) with his human counterpart being able to pull off being forty - eight - years - old . ( PROSE : " Human Nature " ) By the end of his life , however , the Doctor had aged significantly . ( TV : " Doctor Who " ) He was ambidextrous , ( PROSE : " Warlock " ) and had a small tattoo . ( PROSE : " Return of the Living Dad " ) With an animated face , the Doctor had expressive bulgy eyebrow s , ( TV : " Time and the Rani " ) and , according to Ace , three distinctive smiles : his " cartoon grin " , his " secret freak - the - enemy - smile " and his " halfway smile " , the last of which unnerved Ace . ( PROSE : " Love and War " ) Though his eyes were naturally blue , ( PROSE : " Set Piece " ) they would often change colour , ( PROSE : " " ) appearing as grey , ( PROSE : " " ) green , ( PROSE : " " ) brown , ( PROSE : " Transit " ) black , ( PROSE : " Legacy " ) and a mix of blue and grey . ( PROSE : " Toy Soldiers " ) After being stabbed in his left shoulder by Ace , ( PROSE : " The Left - Handed Hummingbird " ) the Doctor would occasionally feel pain emanating from his wound . ( PROSE : " Set Piece " , " Infinite Requiem " , " Return of the Living Dad " ) Ace thought that in his " get - up " , the Seventh Doctor resembled a " dance - hall comic " . ( PROSE : " Fable Fusion " ) Peri Brown described him as a " kooky little guy in a weird pullover " , ( AUDIO : " The Veiled Leopard " ) and Josiah W . Dogbolter also considered him a " pipsqueak " . ( COMIC : " Time Bomb ! " ) The First Doctor described his seventh incarnation as the " short Scottish fellow " who would " turn things to his own ends " . ( PROSE : " Five Card Draw " ) Hair and grooming . While he had a full set of brown hair after his regeneration , ( TV : " Time and the Rani " ) the Doctor allowed his greying hair to grow out into tufts on the sides of his head , while it thinned a bit at the top of his scalp , by the end of his life . ( TV : " Doctor Who " ) Clothing . Main attires . After many failed attempts to find a new look , the Seventh Doctor eventually settled on a single breasted off - white safari - styled jacket with a red paisley handkerchief in his left pocket , a red / black tartan scarf under his lapels , with a yellow pullover adorned with red question mark s and turquoise zigzag patterns , with sand - coloured tweed plaid trousers and a pair of red braces either pulled over ( TV : " Time and the Rani " ) or tucked under the pullover . ( TV : " Paradise Towers " ) Under the pullover , he wore a white shirt with a red paisley necktie , and completed his outfit with a pair of two - tone white and brown brogued spectator shoes . He also had a chained fob watch attached to his left lapel , while the watch rested in his upper left breast pocket . After losing his tartan scarf during his clash with the Rani , ( TV : " Time and the Rani " ) he replaced it with a paisley one . ( TV : " Paradise Towers " ) He wore one navy blue sock and one " Rocky and Bullwinkle " sock . ( PROSE : " Return of the Living Dad " ) As he matured into more of a schemer , the Doctor began wearing a chocolate brown jacket , and changed his hatband , handkerchief and necktie to ones in more subdued shades of burgundy ( TV : " Battlefield " ) and brown . ( TV : " Ghost Light " ) Occasionally , he would remove his pullover as well , ( COMIC : " Distractions " , " The Mark of Mandragora " , " Party Animals " ) and wear a tan brown duffle coat when caught in the rain . ( TV : " The Curse of Fenric " ; PROSE : " Untitled " , " The Highest Science " ) During his escapades as Time ' s Champion , the Doctor replaced his usual attire with a wrinkled cream - coloured linen suit , with a glistening silk shirt worn with a green silk cravat , and a paisley banded white fedora ( PROSE : " White Darkness " ) that he had had made especially for him . ( PROSE : " First Frontier " ) Worn on his lapel would either be Cameca ' s brooch , ( PROSE : " White Darkness " ) or a Smiley Face pin badge . ( PROSE : " Sky Pirates ! " ) He would later replace the cravat with a bright green , ( PROSE : " Tragedy Day " ) paisley blue , ( PROSE : " Strange England " ) or solid red four - in - hand tie . ( PROSE : " Original Sin " ) After his confrontation with the Brotherhood of the Immanent Flesh , ( PROSE : " So Vile a Sin " ) the Doctor had taken to wearing a light brown tweed jacket , with a red paisley waistcoat , a white shirt , green plaid trousers and a black and brown zigzag patterned tie . ( TV : " Doctor Who " ) On his head , the Doctor wore battered cream colonial - styled Panama hat with an identical paisley handkerchief folded into a hatband and an upturned brim . ( TV : " Time and the Rani " ) He later replaced his battered hat with a newer one . ( TV : " Remembrance of the Daleks " ) He also wore a black Tank - styled wristwatch on his right wrist , ( TV : " Time and the Rani " ) which he later replaced with a sportier round watch , ( TV : " Silver Nemesis " ) and then with a rectangular faced tank watch . ( TV : " Battlefield " ) After finding his old signet ring in the TARDIS console , ( COMIC : " The Chameleon Factor " ) the Doctor started wearing it again through numerous adventures , ( COMIC : " The Good Soldier " , " Metamorphosis " ) until he gave it to Joan Redfern . ( PROSE : " Human Nature " ) Other clothes . Whilst in Nazi Germany , the Doctor briefly donned a long black leather overcoat and a black soft hat . ( PROSE : " " ) During his time in Chicago in 1929 , the Doctor donned a grey striped suit and fedora . ( PROSE : " Blood Harvest " ) Whilst visiting Betrushia , the Doctor wore an orange waistcoat , a white shirt with a Gladstone collar and a black cravat with his dark jacket . ( PROSE : " St Anthony ' s Fire " ) On Youkali , the Doctor wore a burgundy - coloured waistcoat and a tweed jacket . ( PROSE : " Return of the Living Dad " ) Umbrellas . After his regeneration stabilised , the Doctor took to carrying around an umbrella as part of his day - to - day outfit , using them as physical props , usually to disarm and trip opponents , He initially carried his previous incarnation ' s multi - coloured umbrella , but was forced to leave it in the Rani ' s base on Lakertya where it was destroyed . ( TV : " Time and the Rani " ) During a clear out , he managed to find a replacement within the TARDIS wardrobe : ( PROSE : " The Useful Pile " ) a black umbrella with a handle . ( TV : " Paradise Towers " ) After his black umbrella was damaged , ( AUDIO : " The Warehouse " ) the Doctor acquired a new umbrella , with an elaborate handle in the shape of a large red question mark . ( TV : " Delta and the Bannermen " ) The handle could split in half and unfold into a makeshift stool , ( COMIC : " Planet of the Dead " ) and was also detachable , hiding a secret compartment containing a vial of Time Lord restorative . ( COMIC : " The Forgotten " ) Attempting to " wean himself off " his umbrella , the Doctor took to carrying a walking - cane as his reign as Time ' s Champion drew to an end . ( PROSE : " Christmas on a Rational Planet " ) Behind the scenes . Casting . Actors considered for the role of the seventh incarnation before Sylvester McCoy was cast included Rowan Atkinson , who later played the ninth incarnation in the satirical " The Curse of Fatal Death " ; McCoy ' s mentor Ken Campbell ; Chris Jury ; Tony Robinson ; and Alexei Sayle . Sayle had previously played the DJ in TV : " Revelation of the Daleks " . Furthermore , Andrew Sachs and Dermot Crowley auditioned for the role . Cartmel Masterplan . Season 25 and 26 had broad hints that the Doctor was not simply a Time Lord , as previously shown and stated . This overarching plot , conceived by Script Editor Andrew Cartmel and referred to by fans as the Cartmel Masterplan , was designed to restore an element of mystery in the Doctor and his true nature as in the stories of the first and second incarnations . Although the cancellation of the series at the end of Season 26 prevented further on - screen exploration of this arc , it was later given full rein in the Virgin New Adventures novel series . Travels with Peri ? In COMIC : " A Cold Day in Hell " the Seventh Doctor is shown to be travelling with Frobisher , a companion of the Sixth Doctor . Frobisher refers to Peri Brown as if she had recently left . The timeline given in the Doctor Who Magazine article " Stripped for action ? " claims that the Seventh Doctor picked up Peri and Frobisher sometime before COMIC : " A Cold Day in Hell " , and in an unknown adventure Peri left the Doctor to live with Yrcanos . whoisdoctorwho . co . uk . The website whoisdoctorwho . co . uk had a list of sightings of the Doctor from which people had ostensibly been submitting to Clive Finch , a conspiracy theorist character from TV : " Rose " . A submission from " j q public " had sighted someone who looked like a version of the Doctor in Clive ' s photographs — the Ninth Doctor — arguing with " a little man with an umbrella " on a university campus .
