Sentinel Mark I

Invented by Dr. Bolivar Trask, the Sentinels are programmed to hunt and kill mutants.

Several types of Sentinels have appeared through the years, manufactured by various private and paramilitary groups, but the typical Sentinel is three-stories tall, possesses the ability to fly, project energy blasts and detect mutants.

The Sentinels have been featured in several X-Men video games and played a large role in the 1990s X-Men animated series.

Sentinel Mark I Drawbacks

Mark I Sentinel’s are strictly programmed and generally unable to operate outside of their operation parameters. They are programmed to protect humanity but have a design flaw that causes them to believe the best way to protect humanity is to control it. (they are still unable to cause harm to humans though)
