The Sentinels are specialized mutant-hunting machines created by Dr. Bolivar Trask as a solution to what he felt was a growing problem caused by superhuman mutants; however, the Sentinels soon grew out of hand and planned on taking over humanity. It was only due to the intervention of the mutant superhero team known as the X-Men did the Sentinels plan for domination toppled. They serve as one of the main antagonists of the X-Men franchise, but also have appeared as enemies of other superheroes as well
However, the damage had been done, and many other villains and misguided souls created new versions of the Sentinels, some driven by hatred of mutants, others simply trying to make the world safer. These Sentinels varied largely in size, function and danger but all of them shared a common trait: they were merciless hunters of the mutant race and a symbol of fear and hate in the eyes of many
In addition to the legions of lesser drones, there have been a number of Sentinels who have evolved beyond their normal programming and have become super-villains in their own right. Examples of these elite Sentinel units would be Master Mold (the supreme leader of the Sentinels in the early years), Nimrod (a future Sentinel of immense power) and Bastion (the mystical-fusion of Master Mold and Nimrod). Later there would be Prime Sentinels human and sentinel hybrids like Omega Sentinel who was a former hero and later comes the main villain in the Krakoa era as the founder and leader of Orchis while creating the Earth-616 version of Nimrod
In their appearances in cartoons and television series, they were voiced by David Fox in the X-Men animated series, Tom Kenny in The Super Hero Squad Show, and Jim Ward in Wolverine and the X-Men
