Saul Tigh

Saul Tigh is a fictional character on Battlestar Galactica played by Michael Hogan. He is one of the main characters of the show.

Occupation on New Caprica
Saul was the leader of the resistance against the Cylons that occupied New Caprica. While he was held in one of the Cylon camps for questions and torture, one of the Cylons ripped out his right eye.

Post New Caprica
After being saved from the operation on New Caprica, Saul tumbled into an angry, vengeful, drunken stupor. The fact that he killed his wife and the other acts he committed on New Caprica is to blame. Eventually, he manages to overcome these feelings and returns as the XO of the Galactica.

Final Five
It was revealed in the season 3 finale that Colonel Tigh was one of the final five Cylons. To say the least, he was not happy to find himself to be that which he had hated his whole life.
