Now that Sentinel Prime has been officially confirmed as a character in the DOTM film, a few questions come to mind: Is he a descendant of the Ancient Primes like Optimus? If so, could there be other descendants that are forgotten, hidden away, and/or nobody knows about? Will his role in DOTM be the same as The Fallen in ROTF, but the opposite? Will he challenge Optimus for leadership of the Autobots? Could he be the key to ending the war between the Autobots and Decepticons and restoring Cybertron? Who do you think will be the voice of Sentinel Prime in the film?
