War Doctor

The War Doctor was a particular incarnation of the Doctor that fought in the Time War. After specifically regenerating into a warrior when he realised that escape from the War was inevitable, the Doctor plunged into the War against the Daleks and witnessed brutal and horrific acts from both sides, some of which he may have even commited himself.

This incarnation of the Doctor ended the War by supposedly destroying everything in it, a decision which his successors regretted immensely. However, it was revealed that he did not destroy the Time Lords or Gallifrey, he had simply trapped them forever in an alternate universe and destoyed the Daleks.

He says things like 'What I did, I did without choice. In the name of peace... and sanity...'. He also shows disdain at his recent incarnations when he meets them, claiming that all they could do by waving the Sonic Screwdriver at their enemies is 'Assemble a Cabinet at them'. Strange.

He also borrows guns from Time Lord soldiers just to shoot graffiti into walls. He once crashed his TARDIS into a Dalek and then made it read the words he had written before blowing it up in a massive inferno. Ha.
