The Sentinels are mutant-hunting robots, specifically programmed to target the mutant X-gene. They are used by Sentinel Services to hunt and apprehend mutants that are too dangerous for agents to approach. They are the antagonists to the X-Men.
The exact history of the Sentinels is unknown. However, they were likely developed sometime after the Sentinel Services.
In eXposed, Sentinel Services surrounded the Strucker family and several mutants from the Mutant Underground (Eclipse, Thunderbird, and Blink) in an abandoned warehouse facility, and ordered them to the ground. When the fugitives refused to comply, they deployed the Sentinels to hunt them down throughout the warehouse. Despite their best efforts, they failed to apprehend the subjects due to Blink's ability to create portals, which allowed them to escape. The robots were able to withstand Thunderbird's strength, Eclipse's heat blasts, and Lauren's force fields. Andy was the only mutant powerful enough to defeat them by tearing the Sentinels apart with his ability.
Physical Appearance Edit
They are small spider-like robots with a rotating red eye in the center. They are extremely durable and can withstand intense physical assaults and intense heat, capable of quickly adapting to damage to continue functioning. They capture mutants by latching onto them with immense grip, even Thunderbird could not break free from a sentinel until Eclipse assisted with an intense heat blast and even then the sentinel continued to function and hunt them. With their spider-like design, they can crawl and maneuver on walls and ceilings.
- The Sentinels made their first appearance in the 1965 comic series titled "Uncanny X-Men #14".
- They also appeared in the X-Men cinematic universe, debuting in X-Men: Days of Future Past as giant humanoid robots.
