Eleventh General

Kenossium, commonly referred to as simply the General, was a General in the Time Lord military.

Early days
Kenossium was, for her first ten incarnations, a woman. (TV: Hell Bent) Like all Time Lords, she was taken from her family at the age of eight for the selection process in the Drylands. Staring into the Untempered Schism as part of a Time Lord initiation rite, she was inspired by what she saw in the Schism. (PROSE: A Brief History of Time Lords)

At the Time Lord Academy, Kenossium was mentored by Bellator, whose lessons taught her how to survive "sixteen transwarp campaigns and a Time War." (COMIC: The Clockwise War) She became the Time Lords' military commander, (TV: Hell Bent) with the rank and title of "the General". (TV: The Day of the Doctor)

The General was present on Gallifrey when the First Doctor stole a TARDIS, and also witnessed the commotion caused by the event. (PROSE: The Day of the Doctor)

Eleventh incarnation
The General's tenth regeneration resulted in a male eleventh incarnation. He appeared as a grey-eyed middle-aged light-skinned bald man (TV: The Day of the Doctor, PROSE: Lords and Masters).

Fighting in the Time War
In the first year of the Last Great Time War, the General led a strike force of Battle TARDISes to the Gates of Elysium. There he saved the War Doctor from the Nightmare Child shortly before Davros was killed. (PROSE: The Third Wise Man)

The General once found the Master in the Siege of the Chronotide, screaming for mercy as the Multiform closed in. (PROSE: Lords and Masters) He led the War Council and its efforts to defend Gallifrey from the Dalek onslaught in the final days of the Last Great Time War. In the aftermath of the Fall of Arcadia, he was informed of the War Doctor's appearance there. He was then alerted to a security breach in the Time Vaults. He discovered that the War Doctor had taken the Moment and intended to use it.

The General was later contacted, much to his displeasure, by the War Doctor, the Tenth Doctor and Eleventh Doctor. They revealed to him their plan to save Gallifrey by freezing it before its destruction and shifting it to a pocket universe. The General was sceptical, shocked by the thought of being lost and forgotten in another universe and stated that the calculations would take centuries. The Doctors informed him that they have recruited all their incarnations to help and that while the Time Lords would be lost, they'd at least have hope which they didn't have at that point with the Daleks bombarding Gallifrey heavily. The Doctors also told the General that the alternative was burning and no one wanted that. As the General continued to hesitate, the Dalek Fleet realised something was wrong and increased their firepower. Realising he was out of options, the General ordered the Doctor to "just do it." The thirteen Doctors then succeeded in freezing Gallifrey and shifting it to a pocket universe, causing the Dalek fleet to destroy themselves while the Time Lords were saved. (TV: The Day of the Doctor)

After the Time War
The General sent on a mission with Yayani to stop Kalub from developing his experiments further, as they would expose Gallifrey if successful. He was present at the location where Missy sent Yayani's shrunken dead body back to Gallifrey. (PROSE: Lords and Masters)

Regeneration
When the Twelfth Doctor returned to Gallifrey, the General discussed the event with Rassilon and the High Council. He told Rassilon that the Doctor had the respect of his men as he was the one who won the Time War and had served with many of them. When Rassilon ordered the firing squad to kill the Doctor, the General protested but made no move to stop them. The squad purposefully missed and sided with the Doctor. When military ships arrived, Rassilon assumed the General had summoned them. However, the Doctor told Rassilon he'd called the ships, all of which chose to provide the Doctor with backup. As Rassilon prepared to kill the Doctor with his gauntlet, the General stopped him, telling Rassilon, "Lord President, with respect, get off his planet." The General then dropped his gun and stood at the Doctor's side against Rassilon. Rassilon was exiled from Gallifrey and the General informed the Doctor that Gallifrey was at "the end of the universe, give or take a star system", and as such, Rassilon could have nowhere to go.

When the General continued to call Rassilon the President, the Doctor corrected him that he was the President now. The Doctor agreed to assist the High Council in learning the true identity of the Hybrid. To do this, he claimed that Clara Oswald had vital information and insisted that she be extracted from the point of her death and brought to him on Gallifrey. The General facilitated this but quickly discovered that the Doctor had merely lied in an extraordinary attempt to save Clara.

The General insisted that any attempt to prevent Clara's death as an established historical event would have grave consequences for the timeline. Attempting to prevent the Doctor from escaping with Clara, the General was threatened by the Doctor who stole his gun. The General and Clara attempted to talk sense to the Doctor with the General reminding the Doctor that the gun had no stun setting. Finally, the Doctor asked which regeneration the General was on. The General realised what the Doctor intended and stated that he was on his tenth regeneration and thus his eleventh incarnation. After the Doctor and the General wished each other luck, the Doctor shot the General which caused him to immediately regenerate, giving the Doctor time to flee with Clara. (TV: Hell Bent)

Twelfth incarnation
The General quickly recovered after regenerating, this time having the form of a dark-skinned woman with a shaven head. She observed that she was "back to normal" and rhetorically asked how men continually dealt with "all that ego". With assistance from Ohila, the General continued to pursue the Doctor into the Cloisters. She exchanged words with Clara and seemed to respect the human's opinion. Unfortunately for the General, Clara had been buying enough time for the Doctor to escape and steal another TARDIS, and the pair fled from Gallifrey. (TV: Hell Bent)

She was present when Bellator chose his final incarnation's form and witnessed his death as he died in her arms when his regeneration went wrong. She was then informed by a Time Lord soldier that the same thing had happened to six other Time Lords the same day. Shortly after this, she was contacted by the Twelfth Doctor to help him in his attempts to solve the mystery of the Clockwise Men. Following his orders, she travelled to 1882 America and recruited Bass Reeves and Totika. They eventually travelled to 2018 London and acted as the Doctor's "cavalry", rescuing him from the hands of Alexander Truscott and the Clockwise Men, having been somewhat held up by the busy traffic of the city.

Joining the Doctor in entering the Dreamspace that Shayde had created around Fey Truscott-Sade, she led the Obsidian Fleet to fight the Clockwise Men. Although this was against the Doctor's wishes, she stated that with the fate of her planet on the line, "we're not going down without a fight". When Fey's spell broke after realising the Absence was never real and that the attacks were her doing, Kenossium and her fleet was returned to normal space. After recognising Fey's efforts, she promised to return Reeves and Totika to their own time. (COMIC: The Clockwise War)

Later life
Many years after the conclusion of the Time War, the General would deny that additional Doctors other than the war, tenth and eleventh incarnations were present in the saving of Gallifrey. (PROSE: A Brief History of Time Lords)

Alternate timeline
After the Cyberman invaded Gallifrey, the General, planning to fight back against the invaders, rescued the Twelfth Doctor from Rassilon with her soldiers, teleporting him in the Tomb of Rassilon. When Rassilon found them, the Doctor opened the door to face him. Rassilon took them to the cyber-converted Eye of Harmony, and put the General inside one of the looms to power it, in order to store regenerative energy to create a new universe. Kenossium was freed after the Doctor and Rassilon joined forces to regenerate the universe back to its former state. (COMIC: Supremacy of the Cybermen)

Eleventh incarnation
During the Last Great Time War, the General was devoted to defeating the Daleks and saving his species. He was shown to be a greatly respected military leader who didn't seem impressed with Rassilon and the High Council's plans to save their species. He was also shown to not think highly of the War Doctor, calling him "the mad fool" and saying that three Doctors arriving was "all [his] worst nightmares at once" and that twelve of them turning up was even worse. He was also stunned by the idea that Gallifrey and the Time Lords' only option was to be frozen in a pocket universe and was knowledgeable about the fact that it would take a very long time to make such calculations. However, he was shown to be able to make quick decisions when the need arose, such as when the Dalek Fleet increased their firepower on Gallifrey and he ordered the Doctor to "just do it" rather than continuing to hesitate over his decision. (TV: The Day of the Doctor)

Following the end of the Last Great Time War, the General gained a great respect for the Twelfth Doctor. When Rassilon questioned who the Doctor thought he was ignoring the military, the General called him "the man who won the Time War" with a respectful tone. When Rassilon ordered the Doctor's execution, the General protested but chose not to disobey orders like his men. However, he also did nothing to stop his men as they sided with the Doctor. When the General defected to the Doctor's side, he ordered Rassilon off Gallifrey in a way that showed he was disgusted with the former Lord President. He did, however, question the Doctor's decision to banish Rassilon, as there could be nowhere for him to go and Rassilon was once a good man. He accepted the decision regardless though.

When he realised the Doctor had manipulated the situation to save Clara Oswald, the General showed no fear as he stood his ground against an armed Doctor, merely trying to get him to stand down. When the Doctor wished him good luck before shooting him, the General did the same, remaining magnanimous towards him to the end despite the fact that the Doctor was about to shoot him. (TV: Hell Bent)

Twelfth incarnation
As a woman, the General showed a distaste for the egos of men and was at least partly relieved to be a woman again. While trying to stop the Doctor, she allowed Clara to say some final words to him before she was sent back to die, showing some compassion and listened stoically as Clara called the Time Lords monsters. However, she was shocked by the Doctor's escape with Clara's help and somewhat panicked by it. (TV: Hell Bent)

She showed great respect for Bellator, due to him being an old mentor of hers. Originally being cheerful, she turned to vicious anger after Bellator died. Although continuing to respect the Doctor by willingly helping him when necessary, she was not afraid to turn against his wishes when the fate of Gallifrey was on the line. (COMIC: The Clockwise War)

Behind the scenes

 * In their first-seen incarnation, the General was played by Ken Bones, who also provided the Time Lord voice asking the Question, "Doctor who?", in The Time of the Doctor. A connection between the voice heard in The Time of the Doctor and the General was never made explicit, although the subtitles on the Blu-Ray and DVD identify the voice as that of "the General".
 * The General's regeneration in Hell Bent marked the first time a gender-swapped regeneration was shown on television. Michelle Gomez's was the first gender-swapped Time Lord depicted on television, but her actual regeneration occurred off-screen. The very first gender-swapped regeneration was depicted in AUDIO: The Black Hole, which was released two weeks before Hell Bent.
 * Incidentally, it was also the first regeneration witnessed in the revived series where the Time Lord in question was lying down, rather than standing up, and the regeneration was far calmer than is generally seen with Time Lords such as the Doctor and.
 * The General's birth name Kenossium, as revealed in COMIC: The Clockwise War, is a combination of the name Ken and the Latin word "ossium" meaning "bones". It is, therefore, a subtle reference to the actor Ken Bones, who played the eleventh incarnation.
 * According to TARDIS Type 40 Instruction Manual, Kenossium wrote an unofficial memoir titled "Thirteen of Them: I Didn't Know When I Was Well Off", which detailed the events at the climax of the Last Great Time War.
 * Following the revelation in Hell Bent that all of the General's regenerations prior to the Ken Bones incarnation had been female, a fan theory emerged that "the General" was a new identity adopted by Romana at the end of the Last Great Time War. Although contradicted by a handful of sources (most notably The Clockwise War giving the General a different birth name from "Romana", and the Twelfth Doctor Doctor Who Experience Interactive Story depicting Romana still in her Lalla Ward incarnation in "the very last days of Gallifrey"), this idea was endorsed by veteran Doctor Who writer Jonathan Morris, who indicated in 2020 that he intended to confirm it in a licensed short story at the first opportunity.
