Powers: Immense strength, laser beam and plasma blasts. The new Prime Sentinels can disguise themselves as human (since they still are, in some way) and have great ability to avoid mutant powers. Pro-File: The Sentinels are behemoths robots, programmed to kill mutants, nothing more. Created by Bolivar Trask, an anti-mutant scientist, the Sentinels have been one of the X-Men greatest enemies. Bolivar Trask also created the Master Mold, who was some kind of Sentinel's mother that created many of the robots. They rebelled against Bolivar and only the force of the Original X-Men was enough to stop them. As Charles Xavier once said, the robots have no soul, no emotions to appeal to, making them the personification of the hatred that humanity feels for mutant kind. There were a lot of Sentinels since their first appearance: the government Sentinels, Stephen Lang's ones, Fitzroy's ones from the future and the futuristic model, Nimrod, that seems to be in production in our time. Nimrods are a lot harder to destroy, since they have ways to repair themselves really quick. With Operation Zero Tolerance, there are the Prime Sentinels. These villains were once regular humans, transformed with nano-technology, becoming Sentinels. This innocent people had suffered accidents that made them to go to a clinic, the Doctor Prospero's Clinic, to get implants, such as legs, arms and other body parts. They didn't know they were being transformed into deadly cyborgs. After the saga was over, nothing was said or done about the search of the cure for these people. It seems that this new model will keep showing up, as we could see in the limited series Wolverine: Days of Future Past
