- "I hate ponies. Ponies are rubbish"
The main character of the blog and the 12th incarnation of the Doctor. Due to an encounter with Discord, instead of being his heroic self, he has become cowardly, womanizing, and outright vicious at times. He tries most of the time to stay in the TARDIS hidden in the time vortex, but he has again and again been forced to leave. From time to time, his original personality manages to emerge, but it doesn't remain permanently and he always reverts to his Discorded state shortly.
