Maxil

Commander Maxil was a member of the Chancellery Guard. Zealous and humourless, he stunned the Doctor and confined him in a cell under the Capitol to await the judgment of Lord President Borusa and the High Council of Time Lords. (DW: Arc of Infinity) He was promoted to Castellan briefly after the death of Andred, but after siding with Pandora and Inquisitor Darkel in the Civil War, he was demoted back to Commander. (BFG: Appropriation)

Coincidentally, Maxil looked almost identical to the Doctor in his sixth incarnation. (DW: The Twin Dilemma)

Behind the scenes

 * Maxil was portrayed by Colin Baker, who later became the Sixth Doctor. As a result of Baker being chosen to replace Peter Davison as the Doctor, the character of Maxil was dropped from the later anniversary story The Five Doctors.
 * Colin Baker has said he made the suggestion that, in DW: The Mysterious Planet, Commander Maxil should have arrested the Doctor and taken him into the trial room.


 * His wasn't the last time a future Doctor would be involved in an earlier production; David Tennant participated in several Doctor Who audio dramas for Big Finish Productions (the first being BFA: Colditz) before being cast as the Tenth Doctor.
 * In BFG: The Inquiry writer Justin Richards had suggested that Maxil should be revealed to be the 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
