Solitar

 History: 

Lord Solitar is the final king of the Sinestral Elves (excluding the Watcher's short reign). His race feared him due to his incredible power. They tried to escape their war as well as him through time, and have the Watcher as their king, but Solitar secretly followed, posing as the Watcher's master. Eventually it was discovered, that his master was indeed Solitar the entire time, who simply wanted to escape the war, and conquer the land to the east in the future, with his great power and empire.

 Plan: 

His entire plan is as follows:
 * Pose as Watcher's master and train him
 * Send him to the future in a cryogenic freeze
 * Have him open a portal to summon the Sinestral Elves to the future, where he'd kill everyone but the army and usurp the Watcher
 * Pretend not to know of the plan
 * Take over
