Twelfth General

The General was the Time Lord military commander who, in his eleventh and only male incarnation, led the War Council, therefore the efforts to defend Gallifrey from the Dalek onslaught in the final days of the Last Great Time War. He had a testy relationship with the Doctor, thinking him a "mad fool".

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, discovering that the Doctor had taken the Moment, the last weapon in the Omega Arsenal and that only he would dare use it.

He was later contacted by three incarnations of the Doctor, much to his displeasure, the War Doctor with the Tenth and Eleventh Doctor, who 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 that the calculations would take centuries. The Doctors informed that they have recruited all their incarnations to help. With the Dalek fleet closing in, he soon gave the order and "all thirteen" Doctors performed the process together.

When the Twelfth Doctor returned to Gallifrey, the General’s submission to the Doctor on his return ultimately confirmed the fall of the Lord President, Rassilon, and the succession of the Doctor in his place. 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 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. Unperturbed, the Doctor shot the General, causing him to regenerate into a woman. The General continued to pursue the Doctor, but his escape through the Cloisters and theft of a TARDIS meant that he and Clara ultimately eluded her. (TV: Hell Bent)

Behind the scenes
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. Although not explicitly confirmed, it can be inferred that the voice asking the Question was that of the General. Indeed, the subtitles on the Blu-Ray and DVD identify the voice as that of the General.
