Headless Horseman

The Headless Horseman was a Chendaki warrior that was tried by the Tachyon Judicial Alliance and sent to Earth as punishment for his crimes. He arrived in Sleepy Hollow in the 19th Century, where he took on the mantle of a supernatural villain, creating a legend.

Character History
The Horseman began life as a warrior, part of the Chendaki race. He committed an unnamed crime and was tried by the Tachyon Judicial Alliance, who cut off his head and sent him to Earth. He was alive, due to the biological structure of the Chendaki race, but he felt as if he had lost his purpose without his head, as the head is considered a vital part of the Chendaki's intimidation. As a result, he took to removing other people's heads as the Headless Horseman, making the catalyst for the story by Washington Irving. The Doctor realised who the Horseman really was and persuaded him to come with him to a planet of outcasts where he could live out his life. He is happy there, and no longer feels isolated.
