The Doctor (Barusa's universe)

In one of the infinite parallel universes of "possible space", (COMIC: Fire and Brimstone) the history of the Doctor was recorded by his grandfather and companion, the Time Lord Cardinal Barusa. (PROSE: The Chronicles of Doctor Who?)

Origins
This version of the Doctor was born on "the Blue Planet" to the Time Explorer Ulysses and a "simple peasant girl" called Annalisse. Ulysses had given up his immortality to be with her. The Doctor's first regeneration occurred on Earth at a very young age. After it, he was taken back to Gallifrey in secret to be raised as a Time Lord under the watchful eyes of his grandfather, Barusa, with no knowledge that his short first life had occurred on Gallifrey. He was also kept unaware about his parentage, believing that he was an orphan and that his half-brother the Master was Ulysses's only son. (PROSE: The Chronicles of Doctor Who?)

Early life
The Doctor spent his following six incarnations largely on Gallifrey, though he often snuck away to Earth to adventure and interfere with history. He was well-liked on Gallifrey, seen as a throwback to the passionate adventurousness and boundless compassion of earlier generations of Time Lords, and was widely viewed as the only man who could stand up to the political influence of the Master, heir apparent to the Presidency, who wished for Gallifrey to become a civilisation of warmongering conquerors, forcing their influence directly on all life-forms in Gallifrey's galaxy. By the age of 800, the Doctor, now in his eighth incarnation, had not changed. (PROSE: The Chronicles of Doctor Who?)

Exile and meeting with the Outcasts
Eventually, Barusa, feeling that his final regeneration was near, announced in the Panopticon that he wished to break with tradition and name the Doctor as his successor instead of the Master's. Faced with bitter disagreement in the crowd, the Doctor took to the stand and delivered an impassioned speech shaming the Time Lords for failing in their duties. This inadvertently turned the majority against him and the Doctor was exiled to the forbidden desert outside the Domed City. There, he wandered for months, nearing death, until he was found by the Outcasts, a secret sect who guarded the secrets of the Tomb of Rassilon. With their help, the Doctor found the Scrolls of Rassilon and brought them back to the Domed City where he found Barusa on his deathbed. Barusa revealed to him that he was Ulysses's son by a human mother before passing away. (PROSE: The Chronicles of Doctor Who?)

Fugitive in time
As the Presidency transferred to the Master, the Master ordered the Doctor executed and the Doctor had to flee, stealing a TARDIS. The instant of his leaving Gallifrey coincided with Barusa's final regeneration, during which his soul left his body. However, instead of taking root in the crystals of the Domed City, Barusa's spirit somehow found itself drawn to the Doctor's TARDIS, merging with it and becoming the Doctor's first and constant companion on his flight through time and space.

Early on in their journeys, the Doctor and Barusa decided to visit the last known coordinates of Ulysses before his disappearance, which turned out to be the Cairo Museum in 1994. There, they found a sarcophagus whose painted face resembled Ulysses's, which turned out to be empty but also to contain a message from Ulysses confirming that he was alive and promising that one day, he and his son would meet again. (PROSE: The Chronicles of Doctor Who?)

Meeting the Daleks
One day, the Doctor's TARDIS was drawn off-course and back to Gallifrey, where the Doctor was summoned before the Time Lord Council. To his and Barusa's surprise, the Master acknowledged the Doctor as his brother and embraced him, offering him a full pardon in the eyes of Gallifreyan law in exchange for going on a few missions on the Time Lords' behalf. The first concerned a species of warmongering cyborg killers who the Master had learned were threatening the outer edges of Gallifrey's galaxy: the Daleks.

The Doctor and Barusa were sent back in time to the Daleks' home planet of Skaro before the Daleks' creation to try and avert it. After discovering that the seemingly benevolent Kaled scientist Davros was actually working on the creation of the Daleks, the Doctor attempted to denounce him to the Kaled High Council, only for Davros to leak the Kaled base's location to their enemies the Thal, resulting in all Kaleds save for Davros and his creations being destroyed. The Doctor later tried to sneak back into the incubator room where more Daleks were being hatched, only to be confronted by Davros, who had let him in as a trap and wanted to feed him to the Daleks. Before he could do so, a further double-cross occurred as the Master himself materialised and revealed to the Daleks how Davros had betrayed their ancestors. The Daleks destroyed their creator and pledged allegiance to the Master, who would go on to have them chase the Doctor through time. The Doctor finally detonated the incubator room, though he could not destroy the Master and the already-living Daleks. He considered going further back in time to undo the entire chain of events, but ultimately could not find the strength to bear the responsibility of altering the history of the galaxy on such a massive scale. (PROSE: The Chronicles of Doctor Who?)

Chased by the Daleks
The Doctor and Barusa continued looking for Ulysses through time and space in the The Doctor's TARDIS, now pursued by the Daleks. They went on many adventures, including encounters with the pirate Blackbeard in 18th century Spain — who turned out to have been Ulysses in disguise —, the war criminal Magnus Greel in 20th century New York City, the marauding cyborgs know as the Cybs, an alien who has merged with a light-house keeper in 1906, an "evil force" known as the Toymaker, the gunslinger Doc Holliday, a group of Neanderthals in Tibet, and with a colony ship where the whole population of the future Earth is frozen in cryo-stasis, only to be preyed on by parasitic insect creatures.

On one occasion, the Doctor also spent some time trying to talk Napoléon Bonaparte into calling off his attack at the Battle of Waterloo, desperate to prevent the deaths of millions. However, Napoléon was unwilling to trust the mysterious stranger, to the Doctor's frustration. When the Doctor walked out of the tent early in the morning and back to the TARDIS, he found Barusa trying to repair the TARDIS's chameleon circuit so that the ship would cease being stuck as a police box, something the Doctor told him off for doing. In turn, Barusa scolded him for meddling in history once again. Eventually the Doctor agreed to leave this timezone with no further meddling to focus on finding Ulysses. (PROSE: The Chronicles of Doctor Who?)

Return to Gallifrey
Eventually, the Doctor and Ulysses were reunited at last, "with great joy". They returned to Gallifrey, bringing with them "all the strength and curiosity that had been lost… (…) passion and, even more importantly, compassion". With Ulysses to prove his lineage, the Doctor was allowed to replace the Master as President and wear the Sash of Rassilon. As the Time Lord population's divides healed, so did the "bottomless crevasses" that were threatening to tear Gallifrey itself apart close again. Barusa's spirit transferred itself from the crystals of the TARDIS to those of the Domed City. In subsequent years, however, the Doctor still occasionally snuck away from his duties aboard the TARDIS to engage in further adventures, just for the fun of it.

Appearance
In his eighth incarnation, the Doctor resembled a man in his 30s. (PROSE: The Chronicles of Doctor Who?)
