The Ninth Doctor was the direct survivor of the Last Great Time War in the Alpha Doon'kin Universe and the Ninth incarnation of The Doctor, but left the conflict with the excruciating knowledge of his hand in its grisly conclusion. Now cut off from the Time Lord race, the Doctor found himself alone and bereaved. Emotionally haunted by the war, he entered a darker period of his life spattered by resentment, where he tended to brood and act crossly to those who rubbed him the wrong way. Despite this, he remained jovial and quite friendly towards anyone he took a liking to, slowly reasserting himself as the Doctor while letting go of his lingering wartime persona. The Ninth Doctor was an emotional incarnation of great sorrow and anger, plagued by the outcome of the Last Great Time War.
