Dynamic, curious and endlessly caring, the **Thirteenth Doctor** was the result of her predecessor's last stand for kindness. This incarnation of the Doctor believed in hope and practiced compassion, providing help to anyone who asked.

After being separated from her TARDIS during her post-regenerative trauma, the Doctor was assisted in her recovery by Graham and Grace O'Brien, Ryan Sinclair, and Yasmin Khan. Following a battle with Tzim-Sha, which resulted in Grace's death, the Doctor accidentally brought Graham, Ryan, and Yaz with her in her search for the TARDIS.

After retrieving the TARDIS, the Doctor planned to take the trio back home, making a few pit stops along the way. However, when they did reach Sheffield, all three decided they would stay. Travelling together, they developed a close, familial bond, calling themselves Team TARDIS.

Though the Doctor tried to keep her past very much behind her, sharing almost nothing about herself with her new friends, the Doctor's history began to catch up with her when she met the Reconnaissance Dalek, one of the first reconnaissance scouts from Skaro and an old enemy. She also encountered a new incarnation of the Master, and discovered that he had ravaged their home planet Gallifrey.

As her whole history began to unravel, with a mysterious past incarnation on the run, Jack Harkness returning, and a Lone Cyberman reawakening the Cyber-Empire, the Doctor eventually found herself back on Gallifrey. Here, the Doctor uncovered the secret of her own past lives as the Timeless Child, a being with the natural ability to regenerate, who was found and adopted by Tecteun. After a series of experiments, the First Tecteun passed on the ability to regenerate to her own people, the Shobogans, who later discovered the ability to time travel and became Time Lords. The Doctor learned that she had been inducted into the Division, a secretive organisation founded on Gallifrey, and that they had taken these memories from her, as well as turning her back into a child with the ability to regenerate only twelve times.

The Doctor spent some time imprisoned by the Judoon, rethinking her identity, before eventually reuniting with her friends with the help of Jack Harkness. However, ten months had passed on Earth, and much had changed without her. After defeating the Daleks together, Ryan and Graham left the TARDIS to resume their lives on Earth. The Doctor continued travelling with Yaz by her side, as co-pilot, who was now fully immersed into the Doctor's world. She also continued to investigate her lost past, pursuing the last surviving member of the Division, Karvanista.

Dan Lewis later joined them as they faced an existential threat like no other: the Flux, a force which would take apart the very structure of the cosmos, bringing about the end of everything. The Doctor was reunited with a new incarnation of Tecteun, who informed her that the Division was behind the Flux, making and placing it in an attempt to destroy a "virus" they had let into their "experiment" - none other than the Doctor herself. After the crisis had been resolved, and a war for control of the remaining universe between the Dalek War Fleet, Cyber-Fleet and Sontaran Empire ended in mutual destruction during the final Flux event, she met the Eternal embodiment of Time, who warned her of her looming final fate.

Seeking the Doctor out in revenge for the destruction of their fleet, Dalek Executioners pursued the TARDIS to ELF Storage, where it was rebooting after damage sustained from the Great Disruption. Unknowingly, however, the TARDIS had trapped the inhabitants of the building in a time loop whilst it rebooted, and any time one of them died, they found themselves reset a minute later than the last loop. Finally defeating the Daleks once and for all in an explosion of fireworks with the help of Sarah and Nick, the Doctor and her companions broke the time loop and returned to a fully repaired TARDIS.
