Sixteenth Master

The seventeenth incarnation of the Master.

Last Great Time War
The Master was resurrected to fight in the Last Great Time War, due to the Time Lords' belief that he would be to the perfect warrior due to his savagery. (TV: The Sound of Drums) He was able to write out most of his involvement in the conflict. (COMIC: The Judas Goatee)

In the body of a small child, the Master made a deal with the War Doctor: to end their old ways of fighting and to become allies. (COMIC: Kill God) He teamed up with the Doctor and his companion the Squire for a time, during the period of the War in which the Cyclors allied themselves with the Daleks. (COMIC: The Organ Grinder)

The Doctor and the Master travelled to Veestrax, where they saw a broken wall with "Exterminhate" written on it. The Master told the Doctor that he hadn't written it. The Doctor then asked for the Master's help with destroying the planet. (COMIC: Outrun)

He arrived on Golgalith with the Doctor asking what he intended to do. The Doctor replied "what I have to". (COMIC: The Then and the Now, The Organ Grinder) The duo soon encountered the Volatix Cabal, together killing one of its members. They then encountered Alice Obiefune, who had travelled in the Master's TARDIS from after the War had ended. The Master set about tethering his future TARDIS to the Doctor's while the Squire set about saving Alice from the Volatix Tendrils.

With both TARDISes in tow, they travelled beneath the surface of Golgalith, where an Overcaste rebel base was located. The Master and the Doctor revealed a Volatix spy in the group and neutralised him. The spy revealed that he had called for help and moments later a Cyclor tore off the roof of the base. (COMIC: The Organ Grinder) The Master decided to use this distraction to flee, sneaking into his TARDIS that Alice had brought from the future. He inadvertently created a paradox when attempting to fly the machine, realising too late that he was erasing a timeline that brought his future TARDIS into being. (COMIC: Kill God)

The chronal tumour began to react with the Psilent songbox, which had been activated by Alice. Realising that it would result in a temporal bomb, the Master deactivated it. The Master was too late, however, and the resulting paradox caused him to regenerate.
