**Isabelle "Izzy" Sinclair** was a human companion of the Ninth Doctor.

Orphaned at a young age, Izzy spent several of her developing years unsure of who she was or who she wanted to be. At the age of eight, Izzy was told that she was adopted. The truth hurt Izzy, and she began to tell herself that she was a lost alien princess, and someday her alien parents would find her. Because of her unknown ancestry, she chose to call herself Izzy S (for "Izzy Somebody") from then on.

When she first met the Ninth Doctor, Izzy was a seventeen-year-old science fiction fan and amateur paranormal investigator. She lived in the town of Stockbridge, England. She was a friend of Maxwell Edison. She met the Doctor after Max and she had stolen an artefact being sought by the Doctor's old enemy, the Celestial Toymaker. The Toymaker had put the entire town of Stockbridge into a pocket dimension and turned everyone into dolls save for Izzy and Max. The Doctor arrived in the midst of this, rescued the town, defeated the Toymaker again and took Izzy on board the TARDIS as his newest companion. The TARDIS landed in the city state of Tar-Ka-Nom, of which Izzy had been reading a tourist log about it's history. The Doctor ended up being implicated in a series of murders, Izzy tried to free by smuggling the sonic screwdriver in through a birthday cake, but was imprisoned too. Remembering the date, from the yet-to-be-written tourist log, as the date the real killer was captured, Izzy left an anonymous tip off on the identity of the real killer.

The Doctor once took Izzy to Jora, where all native life forms were affected by the Syntax. Izzy fell under its influence, and saw Jean-Luc Picard whilst hallucinating. Wanting to solve the mystery behind the disappearance of the 56th issue of *Aggrotron!*, one of her favourite comics whilst she was growing up, Izzy had the Doctor take her to her local comic shop the day the comic released, where the Suits destroyed all the copies and tried to wipe her memory of the incident. The Doctor traced the incident back to the comic's extraterrestrial publishers and the culprit to 51st century native Derek O'Dell, who had adopted the identity of *Aggrotron!*'s star character Courtmaster Cruel to become a vigilante hero in his time. Derek confided his motive was to suppress the twist of Issue 56 that the Courtmaster was a woman, which greatly shocked Izzy. To the Doctor's bewilderment, she agreed with Derek that it should stay secret. The Doctor swapped the Crystal of Consciousness with an identical duplicate, which Valis stole. Valis restrained the Doctor and Izzy, having them at his mercy, when the fake crystal backfired on him upon it being placed in Valis' psychic web. Izzy mocked this substitution as obvious. At one point, Izzy played a collection of video games on the TARDIS Time-Space Visualiser, one of which was *Happy Deathday*. In London, 2001, Izzy was nearly eaten by human-morphant hybrid Donald Stark before her memories of the Doctor repelled him, and was instead taken prisoner as leverage against the Doctor. She was saved by the efforts of Grace Holloway, after which the three of them were able to able to destroy the creature.

In 17th century Japan, after being separated from the Doctor following capture by clan Rikushira, Izzy was saved from Gaijin nano-drones by Sato Katsura. While infiltrating the Rikushira palace, Izzy's mind was forcibly read by Lady Asami for information on the future, which revealed to her the atomic bombings of Hiroshima and Nagasaki in World War II, and drove her to madness. The nano-drones began a rampage using Asami's fury and imagery from Izzy's mind (a giant robot and a Godzilla-like creature), and Sato was mortally wounded protecting Izzy and the Doctor from them. The two saved him with a Gaijin hibernation chamber, unwittingly giving Sato immortality, to his grave displeasure. After the TARDIS collided with Beep the Meep's starship, the two vessels ended up in the BBC Television Centre of a parallel universe. Beep proceeded to enslave the Doctor and the centre's occupants with black star radiation via a star drive, leaving Izzy alone against the alien until she ran into Tom Baker. She convinced the actor to confront Beep and distract him with his ramblings, allowing her to sabotage the star drive and break the Meep's mind control. Before leaving, Izzy explained her solution to the Doctor while showing him a copy of *Doctor Who Weekly*. Finding themselves aboard Qutrusian Cargo Freighter X-703, under assault by space pirates led by Grast Horstrogg, Izzy and the Doctor then met Kroton, a Cyberman who had regained his individuality and a sharp wit. The three resist the pirates and follow the TARDIS after it is brought by Tobal Reist to a nearby asteroid, and as the pirates fought for control of both the ship and the superweapon the Eraser, the Doctor stole the weapon's power source while Izzy ordered the Eraser to self-destruct. Kroton then saved the both of them as the self-destruction eradicated the asteroid's atmosphere, joining their travels in the TARDIS.

On Paradost, Izzy and Kroton bore witness to the Church of the Glorious Dead as the Ash Wraiths ravaged the planet, becoming fugitives after the Doctor vanished into the the Glory. After helping to destroy the Wraiths, she was shrunk by a tissue compression eliminator wielded by Chruch Cardinal Morningstar, though uniquely she survived the shrinking. Captured by the Cardinal, he revealed himself to her as Sato Katsura, having allied with the Master in his scheme for control of the Glory to take revenge on the Doctor while turning Earth into Dhakan in a holy war. As Sato was forced to fight a vengeful Kroton who believed Izzy dead, Izzy herself escaped capture and reached the TCE, restoring her to full size. With a Mnemonic crystal she had gotten on Paradost, she diffused the fight by convincing Sato to repent with her experience as a fugitive, and letting Kroton experience the life he lost from cyber-conversion. Her actions revealed to Esterath that Kroton was worthy of being his successor as controller of the Glory, ending the conflict for control the Doctor and Master were engaged in, reverting the destruction the Master and Sato had wrought, and giving Sato the peace of death. Izzy joined the Doctor in inspecting Blueberry House, an institute for rehabilitating robots with “severe programming deviancy”, where she was trapped inside a chamber with the mechanical patients in a scheme to force them into being subjected to an Adjuster to restore their "normal" programming. Instead, however, she befriended the robots, revealing to the Doctor the sentience and society they had developed. Allying with the egglike Emperor Zero after correctly suspecting the Doctor was in danger, she helped them break out of the chamber and intercept the Adjuster after Andrelina Hastoff tried to silence him with the machine. She and the Doctor remained after the robots mourned Zero following his sacrifice to destroy the Adjuster and overthrew the institute staff, capturing Hastoff in the process. Before leaving, she had a heartful goodbye with a ducklike robot who said "goodbye" as its first words to her, and would go on to tell their story and her role in it for generations to come.

After trying on some bright new clothes from the TARDIS wardrobe, Izzy witnessed as the ship was swallowed by a gigantic, snake-like spacecraft called Ophidius. Exploring the inside, Izzy and the Doctor met Destrii, an amphibious alien who looked like a humanoid fish. Destrii gained Izzy's confidence and friendship, both finding they enjoyed old Earth television shows like *Star Trek*, only for Destrii trick her into switching bodies with her to evade capture by the aliens who controlled Ophidius. When Destrii (in Izzy's body) was apparently disintegrated by a vengeful Mobox, Izzy had to deal with the possibility she would be in an alien body for the rest of her life. Reacting badly, Izzy had a breakdown in her bedroom in the TARDIS, lashing out at the Doctor when he tried to help, refusing his comparisons of her experience to his own regenerations. Shortly after, Izzy began to suffocate as her new body needed to be submerged in water periodically. The Doctor carried Izzy through the TARDIS to the swimming pool, submerging her in the water. Izzy then learnt how to breathe in her new body, and apologized to the Doctor for pushing him away. Izzy then tried to dress herself in her old clothes, but discovered they no longer fit her scaly, alien body. (TV: *Ophidius*)

At the TARDIS's next stop in Coyoacan, Mexico on the 1941 Day of the Dead, Izzy was found by Frida Kahlo and Diego Rivera after being hit by their car when fleeing a Torajenn that had just stolen the flesh of a local couple. While Diego sought after and aided the Doctor, Izzy saved Frieda from a Torajenn that had appeared as her father, and the two went out to warn the city of the aliens posing as the spirits of the dead, Izzy herself setting off fireworks that disrupted the Torajenn's disguises. During this, Frida helped Izzy come to terms with her condition, relating to her through her experience recovering from a broken spine, and personally saving Izzy from a Troajenn who appeared to her as her real body. After the crisis, Frida painted Izzy a portrait of her human self. The Doctor then took Izzy to the marine research submarine *Argus* on Kyrol, where Dr. Alison Lavelle was able to help her better adjust to Destrii's biology. While enjoying a swim in the sea outside the sub, she was the first to encounter the humanised Daleks, and was taken away to their hidden city of Azhra Korr separately from the the *Argus* crew. As tensions escalated between the human crew and the Daleks, the former began to reject her due to her alien appearance, and when she attempted to retrieve the TARDIS from underwater, one of Kata-Phobus's tentacles stopped her. Following the Daleks' self-destruction to kill the creature, she and the Doctor were about to enter the TARDIS and leave when Hassana and Helioth, the powerful twins of the Horde, kidnapped her, under the belief she was Destrii.

When she awoke, Izzy discovered she had been taken on the order of Destrii's mother, the Matriax Scalamanthia of her homeworld planet Oblivion, who wanted her "daughter" to prepare for her wedding by fighting a duel to the death. (COMIC: *Oblivion*) Meanwhile, trying to trace Izzy's whereabouts with the help of his former companion Fey, the Doctor discovered that Destrii in Izzy's body was still alive, (COMIC: *Uroboros*) and arrived on Oblivion with her to both save Izzy and switch their bodies back. As Izzy was put into the arena against Lady Tetronnia, Destrii arrived just in time to stab her adversary in the back, after which Hassana and Helioth chose to swap back their minds. In the process, Izzy and Destrii saw into each other's minds, and Destrii saw how finding out she had been adopted made Izzy withdraw emotionally, unable to trust herself or admit she was a lesbian, while Izzy saw how Destrii suffered an abusive childhood, made into a lethal warrior, and only found respite from her uncle Jodafra and the 1960s Earth television he had let watch. After Destrii killed her mother in a fit of anger, unleashing the Horde who bestowed upon her the powers of their leader, Izzy used her newfound insight into her counterpart's life to remind her of her need for freedom, ultimately helping her lead the Horde off the planet and into Jodafra's chronon capsule.

The Doctor would in the end force her to leave, deeming it too dangerous for her to stay, despite her attempting to tell the Doctor that it was not his fault that Chang, Alex, Fey and Hex all died. Afterwards, Destrii returned to the TARDIS, and both sharing the same body, eventually found attraction to her. The two married, and via Destrii's species' genetics, they were able to have four children, Anatos, a son, Suyil and Primatix, daughters, and Xohmi, a genderless child. She learned of Destrii's species' near-immortality and lived on Destrii's planet as a housemaid and servant while Destrii remained the head of the house. According to Destrii and Destrii's brother, Lurmoxx, they could live for up to 1400 years. Izzy had only been in Destrii's body for 126 years when her body was suddenly reverted back to a human, albeit around thirty years older. She nearly drowned underwater before Destrii took her to the shore due to her quick swimming speed. Izzy was later transported to Earth by an unknown force, but not before saying goodbye to her wife and family. According to a conversation she had with Anders Hausner whilst forming the Coalition, she and the Doctor remained friends, and later incarnations would even take her on adventures.

Decades later, Cornelius Duncan was looking at the Doctor's companions listed on the TARDIS, he found Barbara, Dodo, Polly, Zoe, Liz, Romana II, Nyssa, **Izzy Sinclair**, Ashley and Destrii to be relatively beautiful, later being scolded by Jericho for his remarks. (TV: *The Chainsaw Massacre*)
