Eleventh Drax

Drax was a renegade Time Lord with a knack for tinkering. He knew the Doctor before either had left their home planet of Gallifrey.

Youth
Drax attended Prydon Academy with the Doctor in the Class of 92. They took the tech course together. Though his practical work was satisfactory, he failed his exams, done in by temporal theory. (TV: The Armageddon Factor). Whilst he was at the academy, Drax became a member of the Deca and had his own self-made skimmer. (PROSE: Divided Loyalties)

As a Renegade
Drax had already escaped from Gallifrey when the Doctor was expelled from the Time Lord Academy. (PROSE: Divided Loyalties) Upon going renegade, Drax travelled the universe, doing repair and maintenance work in the fields of cybernetics, guidance systems and armaments. When Drax's TARDIS suffered a breakdown in its hyperbolics, Drax was stranded on Earth. He engaged in criminal activity to procure replacement parts and did time in Brixton prison.

Later, the Black Guardian's agent, the Shadow, imprisoned Drax and forced him to build and maintain a giant computer called Mentalis on the deserted planet Zeos. Mentalis carried out a war against the neighbouring planet of Atrios.

Four hundred and fifty years later in their personal timelines, Drax and the Doctor met again. While searching for the last segment of the Key to Time, the Fourth Doctor and Romana arrived on Zeos. Drax, under the Shadow's orders, reluctantly led the Doctor into a trap. Easily seeing through Drax's pretence, the Doctor talked him into joining forces against the Shadow. With Drax's assistance, the Doctor recovered the final segment of the Key to Time. Afterward, Drax stayed on Atrios to help rebuild that world. (TV: The Armageddon Factor)

Personality
Drax showed great technological aptitude. However, he could not grasp temporal theory and failed the class. (TV: The Armageddon Factor)

During his prison stay Drax picked up Brixton's local accent and idioms, which remained part of his speech patterns after he left Earth and resumed his travels. When Drax met K9 Mark II and marvelled at the "little tin dog", K9 noted Drax's silliness. Although Drax was not above criminal activity and weapons dealing for personal gain, he displayed a sense of what was morally right and bemoaned having to assist the Shadow in his schemes. The Doctor talked him round to joining him against the Shadow without much trouble. (TV: The Armageddon Factor)

Behind the scenes

 * Drax was Barry Jackson's third guest role in Doctor Who, after Ascaris (TV: The Romans) and Jeff Garvey (TV: Mission to the Unknown).


 * The exchange between the Doctor and Drax regarding his accent in The Armageddon Factor would be echoed centuries later in a similar exchange between Rose Tyler and the Ninth Doctor in Rose.


 * Although Drax's TARDIS is somewhere around in The Armageddon Factor, only components from it are seen on-screen. The interactive Make Your Own Adventure with Doctor Who book Search for the Doctor included Drax as a character, in which his TARDIS was in the shape of a convertible car, the registration plate of which read TARDIS.
