Maxil

Commander Maxil was a member of the Gallifreyan Chancellery Guard. Zealous and humourless, he stunned the Fifth Doctor with a staser blast and confined him in a cell under the Capitol to await the judgment of Lord President Borusa and the High Council of the Time Lords. (TV: Arc of Infinity)

He was promoted to Castellan shortly after the death of Andred. (AUDIO: Lies) After siding with Pandora and Inquisitor Darkel in the Gallifreyan Civil War, he was demoted back to Commander. (AUDIO: Appropriation)

Behind the scenes

 * Maxil was portrayed by Colin Baker, who later became the Sixth Doctor. As a result of Baker being chosen to succeed Peter Davison as the Doctor, the character of Maxil was dropped from the twentieth anniversary story The Five Doctors.
 * Maxil shoots the Fifth Doctor at one point during Arc of Infinity. As a result, Baker has often joked that he gained the role of the Doctor by shooting the incumbent.
 * Colin Baker has said he made the suggestion that, in The Mysterious Planet, Commander Maxil should have arrested the Doctor and taken him into the court room on Space Station Zenobia.
 * This is not the only time a future actor to play a Doctor would be involved in an earlier production on screen. Peter Capaldi, who would later play the Twelfth Doctor, appeared in The Fires of Pompeii (TV story) alongside the Tenth Doctor, David Tennant.
 * In addition, David Tennant participated in several Doctor Who audio dramas for Big Finish Productions (the first being Colditz) before being cast as the Tenth Doctor.
 * Justin Richards had suggested that, in The Inquiry, Maxil should be revealed as the Sixth Doctor, who chose to remain on Gallifrey in the timeline in which Minyos was not destroyed by the time bomb. However, Gary Russell felt that this development would be too complicated.
