*Created by Boliver Trask, Sentinels are robots programmed to rid the world of mutants. There have been many versions of Sentinels, including ones from the future like Nimrod. They learn from their mistakes and come back smarter each time. In addition to a wide variety of armaments, Sentinels have immense strength, boot jets for flight, and the ability to neutralize mutant powers. *Source: Back of card
