Doctor Who: 10 Reasons Why We Need A War Doctor Spin-Off

5. The Master As A Soldier

Rassilon was not the only Time Lord to have been resurrected to fight in the Time War. When the Doctor encountered the Master in the episode Utopia, we learnt that the renegade Time Lord fought and fled from the war by using a Chameleon Arch to rewrite his biology. It's possible that the War Doctor may have fought shoulder-to-shoulder with the Master during the Time War. It would be brilliant to see a less restrained incarnation of the Doctor combining his genius with the cruel, calculated cunning of the Master in order to defeat a common foe. The same goes for the other renegade Time Lords that popped up on occasion in Classic Who.
