The Forgotten (comic story)

 was a Tenth Doctor comic published by IDW from 2008 to 2009. It is notable for its inclusion of many historical Doctor Who elements.

Summary
The Tenth Doctor discovers a museum dedicated to his lives and has to remember events from his previous incarnations in order to restore his fading memories.

Issue 1: Amputation
The Tenth Doctor wakes in a strange room without the TARDIS or the sonic screwdriver. He finds Martha Jones. Together they explore the building. They soon learn it is a museum dedicated to the Doctor.

The displays consist of things such as a Dalek gun, the Seal of Rassilon and a Voord helmet. They enter a large room where the Doctor's clothes from his previous nine incarnations are found, along with some thing he used during that incarnation (jelly babies, a walking stick, a recorder, psychic paper, etc.). The Doctor mentions how he'd be lost without his previous incarnations.

A strange man in a darkly lit room decides to test that theory. The Doctor suddenly becomes very weak. He realises he can't remember anything from before his encounter with the Sycorax on Christmas Day a couple of years ago.

Martha brings him his walking stick from his first incarnation and he tells her a story (when Susan, Barbara and Ian were travelling with him) of how he saved a pharaoh's life with that staff. He tells how and when he dropped Ian, Barbara, and Susan off. Martha asks if he thinks that Susan is dead and he replies in the affirmative and mentions that, as far as he knows, he is the last, although the Doctor mentions he left Susan on a future Earth with a freedom fighter she fell in love with. The strange man chuckles and says, "If only that were true." He reveals (talking to himself) how he will force the Doctor to regenerate so he can steal the Doctor's remaining incarnations. He tells Martha that one of his hearts has stopped; he collapses into unconsciousness.

Issue 2: Renewal
The Doctor has fallen into a coma. Martha performs CPR on him and he wakes up. The Doctor and Martha explore more of the museum and find the recorder he played in his second incarnation. He tells Martha about his second incarnation.

The Second Doctor is on a space ship with Jamie and Zoe. They find it has been attacked by snake-like creatures. They help the crew of the spaceship defeat them by playing on the recorder. Back in the museum the man watching the Doctor and Martha releases an Auton, ready to kill the Doctor and Martha.

The Doctor remembers his third incarnation as Martha hands him the keys to Bessie, the car he used to drive while he worked for UNIT. He, the Brigadier and Jo Grant are in a car, chased by giant, spider-like robots, with humanoid dogs as drivers. Jo uses her make-up mirror to aim the laser beams at the ships and the Doctor uses his sonic screwdriver to destroy the dog-like aliens, with Captain Yates's help.

Back at the Museum the Auton approaches the Doctor and Martha. The Doctor fires a can of Nitro 9 at the Auton, killing it. The Doctor checks the readings of the TARDIS' key. Horrified by the absolute lack of response, he tells Martha that it means the TARDIS has been destroyed.

Issue 3: Misdirection
Martha asks if the TARDIS is actually gone. She and the Doctor return to the costume room and find a bag of Jelly Babies. This reminds him of his fourth incarnation.

He recalls taking Romana II to Paris for the second time, in the year 2000. Romana notices a mime posing. She thinks he is trapped in time, but a time hole appears near him. The mime, the Doctor and Romana fall through the hole and land in a late 17th century sewer. They are soon questioned by guards; the Doctor makes up an alias so he can have an excuse to boss them around. Following the trail, they reach the exit door, which is guarded by Taureau the Minotaur, who agrees to let them pass if they answer his riddle. When Romana fails miserably to answer correctly, the Doctor opens a wall, causing an explosion, killing Taureau and the mime. The Doctor and Romana escape through it.

Back at the museum, the Doctor says to himself that Romana did pretty well for herself—until the Time War. He notices Martha has gone. He finds a cricket ball in his pocket. He thinks about his fifth incarnation.

The Fifth Doctor is playing cricket near Allen Road. Tegan Jovanka and Vislor Turlough are watching. All of a sudden a Judoon ship flies over. The Doctor asks Turlough to fetch his five hundred year old diary, while he and Tegan go to meet the Judoon. It turns out the Judoon have landed on Earth in search of the Eye of Akasha. Turlough returns and the Doctor fetches the Eye from the TARDIS before doing a switch with his cricket ball. He gives the Judoon the ball.

In the museum the Doctor finds Martha. She is holding Ace's baseball bat, ready to defend herself. The strange onlooker releases a swarm of giant spiders from Metebelis III, surrounding Martha...

Issue 4: Survival
The Doctor arrives and distracts the Metebelis 3 spiders with the crystal from his sonic screwdriver, which is similar to the type they search for. He and Martha escape and the Doctor vaguely recalls the phrase "There's something on your back." He collapses and begins to fade again. Martha hands him his sixth incarnation's cat brooch and goes off to hunt for the "Time Bracelet thing" and another screwdriver in the Fourth Doctor's costume, while the Doctor recalls a memory from his sixth life involving the brooch.

He remembers when he and Peri Brown were in the court of an animal people with Peri accused of the first-degree murder of Professor Mis'Kin Karac. On the first day of the trial, Peri tells the court how while in the market, a boy pushed a gun into her hands. It fired, killing the professor as he left the building. Peri says she never meant to kill anyone and the Doctor calls off questioning.

On the second day, Professor Karac's assistant offers evidence against Peri and the judge calls a recess until the next day. The Doctor gets the assistant's permission to check out the lab, where the professor and he had been working on quantum flux technology. The Doctor finds the murder weapon in the lab and comes up with a plan.

The next day in court, the Doctor pulls out the gun and aims at Peri, explaining that it is tagged with a genetic signature which the bullet uses to find its target. He also explains this was why the professor's assistant was behind Peri: so he could fire through her at the professor and make it look like she, being the one with the gun, had done it. He tells the assistant how he is currently wearing a cat brooch doused in chronal energy and with a drop of his blood on it. If he fires, the bullet will kill him, not Peri. The assistant confesses and is taken away. As Peri and the Doctor leave, the Doctor explains that the gun wouldn't have worked. He was bluffing, a bluff which the assistant fell for.

Back in the museum, the Doctor speaks through a camera to the mysterious onlooker, who says that he and the Doctor have much in common, except for the obvious, and that he should have left him in the Crucible. The Doctor challenges him to come out, holding up an umbrella and remembering his seventh incarnation.

He recalls the time that he and Ace ended up in the war of Angrivan Seven, which was declared a non-intervention site by the Time Lords. Someone had given the Strykes a Gallifreyan virus to use on the Marats and the Doctor had to stop it. They were captured by the Strykes, but escaped due to an air strike. They met a Marat, who took them to the Marats infected by the Strykes' new bioweapon. The Doctor met with Doctor Treykan and gave her the antidote to the plague, hidden in his umbrella. He seemed to talk to the current Doctor, telling him to fight to survive.

Back in the museum, the Doctor finds the same restorative inside the umbrella and begins to hear the Cloister Bell. He declares the impossibility of this, as it can only be heard in the TARDIS, the Time Lord Matrix or on Gallifrey, none of which they are at--or are they?

Martha demonstrates knowledge of the Cloister Bell she shouldn't yet have and the Doctor remembers her saying he isn't the only doctor in the TARDIS, though she's only a medical student. The Doctor wonders again what's really going on. The mystery onlooker says they can't have the Doctor remembering his future just yet and sends out a Clockwork Droid and a Voc Robot. In the TARDIS with the Cloister Bell tolls, the interior red and an alien life form attaching itself to the unconscious Doctor...

Issue 5: Revelation
After the Cloister Bell rings, the Doctor begins to question who or what Martha really is. They are attacked by a Clockwork Droid and a Voc Robot. The Doctor and Martha escape. Martha hands the Doctor a cravat from his eighth incarnation and the Doctor begins to tell Martha about that life.

The Doctor was alone in a prison cell on a planet, wondering whether the Last Great Time War was still being waged, when the cell door opened and the guards threw a new prisoner into the cell. Sixteen days later the Doctor and his new cellmate, Chantir, saw through the cell window a spaceship land. The Doctor said it was time to escape. The Doctor slowed his heartbeats to almost nothing and Chantir called in the guards. The Doctor and Chantir overpowered them and stole their laser weapons. The Doctor opened all the other cells to allow the other prisoners to escape.

They travelled to the end of the hall and blasted open the door. Inside, the Great Key stood on a pillar in the centre of the room. The Doctor picked it up and told Chantir he planned to use it to recreate the De-mat Gun and possibly even modify the original to increase its lethality to remove millions from time and space at once. The Doctor and Chantir escaped from the prison by sliding down a power cable on the outside wall of the prison. Chantir left the Doctor to find his crewmates and the Doctor walked a few miles to recover his TARDIS.

Martha asks if the Doctor was always alone in that regeneration. The Doctor explains to Martha that his eighth incarnation started and ended alone, because the Last Great Time War happened. He remembers how he saw Arcadia destroyed, laughed in the face of the Nightmare Child, Gallifrey sacrificed, which burned when the Cruciform fell, and how he ended the Time War with the Great Key that turned "the lock" and doomed everyone.

Martha has the Doctor acknowledge that the victims knew the cost of what the Doctor did- saving everything else. She makes the Doctor focus his thoughts on what happened immediately after the war, such as meeting Rose, and gives him the psychic paper. The paper displays the message, "Everything is not as it seems". The Doctor ponders that he spent much more time in cells and brigs than saving the universe before he had this utility and he remembers his ninth incarnation.

The Doctor and Rose arrived in a World War I trench on Christmas Day and the Doctor showed the British occupants documents identifying him as Brigadier Bambera with the psychic paper. A football landed in the trench and the Germans asked the British to hand them back their football. The Doctor challenged the Germans to a football match for their ball. As the British played football with them, the Doctor refereed. After the match, the Doctor and Rose left in the TARDIS.

Martha hands the Doctor the Chameleon Arch and the Doctor regains the last of his memories. At that very moment, an individual resembling the Meta-Crisis Tenth Doctor, but calling himself the Valeyard, arrives with the Clockwork Droid and the Voc Robot and threatens to steal the Doctor's regenerations so he can regenerate himself.

Issue 6: Reunion
As the Meta-Crisis Tenth Doctor finishes his threat, the real Doctor laughs mockingly. He claims to have known it was a bad fake made by the creature who was responsible for the entire mess, using bits and pieces of the Master, the Valeyard and the Meta-Crisis Doctor to fabricate a poor amalgam to bedevil the Doctor.

Infuriated at his plans being exposed, the being identifies itself: Es'Cartrss of the Tactire, a parasitic race known as the Cranial Parasites. It tells him of how his planet was one of the many the Daleks had stolen to power the Reality Bomb. He infiltrated the Crucible until its destruction, then entered the Doctor's TARDIS and attached itself to him in the effort that began the story.

The Doctor uses the distraction to flee and "Martha" gives him the final clues to realise what she truly is - the TARDIS' own mind, desperately trying to help its pilot shake off the parasite. The entire museum was actually the TARDIS matrix. Upon discovering this, the Doctor realises realises that the TARDIS could assume the form of anyone who had ever travelled with him.

Prompted by the Doctor, the TARDIS assumes a variety of disguises of many past companions geared for combat, such as Steven Taylor, Leela and Harry Sullivan, while the Doctor examines the baseball bat. He realises it was, in fact, a chameleon circuit covering the Great Key of Rassilon, the final key to the last door of the Matrix, the one the robots had been so desperate to keep them away from.

The TARDIS begins assuming other shapes better suited to specific tasks, like Kamelion, who shrugged off attacks by the Voc Robot and the Clockwork Droid to open the door with the Great Key; Sarah Jane Smith; and Adric, whose intellect allowed him to design a way to break the parasite's hold on the Matrix by blowing himself, the infected Matrix components and the droids, with one of Ace's old Nitro 9 cans.

Confronted by the last of the Tactire, the Doctor implements his plan - reminding the Matrix there was only one Time Lord in existence: himself. As he speaks, the power of the items he has gathered coalesces, and summons all of his other forms at once - ten Doctors against a Tactire. He offers his enemy a final chance and Escart'rss rejects it. Sighing, the Doctor asks the Matrix to eliminate all non-Time Lords from itself, purging the system of Escartr'ss.

The Doctors converse briefly. The Tenth is surprised, not realising it could be done, despite some squabbling and complaining on every side. Leaving his memories, the Doctor and "Martha" walk through the museum to the exit, modelled after the TARDIS. Having lost his key, the Doctor wonders how to open the doors, until Martha reminds him River Song already taught him how. Smiling, the Doctor thanks her and snaps his fingers. The doors open and flood the museum with light. Before leaving, he asks the TARDIS to assume a final form and she agrees.

Susan Foreman appears before her grandfather, who begs her forgiveness and asks if she's had a good life. She hugs him and soothes him, saying she understood his thoughts and that she always knew he was doing the right thing. She beckons him to walk into the light, and the dream ends.

The Doctor awakens inside the real TARDIS, and kicks the now-mindless Tactire out of the way. Reflecting how he's never truly alone with his oldest companion, he thanks her and decides to go on a little adventure - to Barcelona.

 * The Tenth Doctor refers to Romana II's involvement in the war, and claims that it didn't turn out well for her.
 * The Tenth Doctor states that he succeeded in ending the Last Great Time War using the Great Key. It is implied that this key was used to create the time lock, which closed off the war from the rest of the universe and repelled any time travellers from entering by normal means.

Species

 * The First Doctor mentions that the Egyptian gods Sutekh and Horus were aliens.
 * A Sea Devil is seen as a prisoner during the Eighth Doctor flashback.

Continuity

 * During the First Doctor's vignette, presented in monochrome as a reference to the early seasons of the series being aired as such, the Doctor hopes the TARDIS team doesn't end up in an Aztec temple. The Doctor and his companions did this in TV: The Aztecs.
 * The Doctor encountered Kublai Khan in TV: Marco Polo.
 * The Tenth Doctor recalls Susan's departure in TV: The Dalek Invasion of Earth and the return of Ian and Barbara to more-or-less their original time in TV: The Chase. The Doctor states that he doubts that Susan is still alive, and adds that, although he "can't prove it", he believes all the Time Lords are gone. This follows on from his earlier discussion of the Time War with Martha in TV: Gridlock and the return and death of in TV: Utopia and Last of the Time Lords.
 * The Third Doctor tale is set in 1972 during the Doctor's exile on Earth.
 * The mysterious man at the controls in Issue 1 sports a beard similar to that sported by the and  incarnations of the Master. The Doctor himself comments on the similarity when he tries to use one of the Master's devices on him. Later, the character's identity is revealed to be an insectoid creature impersonating the Meta-Crisis Tenth Doctor.
 * The Tenth Doctor has experienced heart stoppage on prior occasions, beginning in TV: The Christmas Invasion.
 * During the Eighth Doctor's flashback, it is suggested that his statement of being "half-human" in TV: Doctor Who was a ruse.
 * The final issue establishes that the events of The Forgotten occur immediately following the final scene of TV: Journey's End.
 * In the Ninth Doctor tale, Captain Jack Harkness is mentioned. A soldier mentions a Captain Harkness being shot in the head and surviving with "not a scratch to be seen", suggesting this is the version of Jack who is already immortal.

At this point in their timeline, the Doctor and Rose have not met Jack yet. (TV: The Empty Child)
 * Also during the Ninth Doctor tale, the Doctor uses the name of "Bambera" to pass in World War I.
 * The Advocate later claims that the modified De-mat Gun becomes the Moment. (COMIC: Don't Step on the Grass) Statements made by the Time Lords suggest otherwise, indicating it was created by the ancients of Gallifrey. (TV: The Day of the Doctor)
 * A Heavenly Host's disk is in a glass case in the TARDIS Matrix. (TV: Voyage of the Damned)
 * The Doctor tells the fake Martha that he was all alone when his eighth incarnation died. This was shown in [TV]]: The Night of the Doctor, where he was indeed alone and companionless when dying, losing his life after travelling by himself, avoiding the Time War. After dying in a spaceship crash, the Doctor was briefly resurrected by the Sisterhood of Karn, and was given the chance to choose the nature of his next incarnation before he truly perished. Opting to become a warrior, he demanded to be alone before he began to regenerate.
 * The Tenth Doctor indicates his plan to use the Great Key as a way of ending the Time War failed. His war incarnation eventually chose to prime the Moment for detonation as a last resort after he had exhausted all other alternatives. (PROSE: Engines of War, TV: The End of Time, The Day of the Doctor)
