The Sentinels are a group of mutant-hunting robots appearing in American comic books published by Marvel Comics. They first appeared in The X-Men #14 (November 1965), written by Stan Lee and illustrated by Jack Kirby. The original Sentinels were created by Bolivar Trask, and they are typically depicted as antagonists to the X-Men.

The Sentinels played a large role in several X-Men animated series and have been featured in a number of X-Men video games. The Sentinels are featured prominently in the 2014 film X-Men: Days of Future Past, and made brief appearances in the 2006 film X-Men: The Last Stand and the 2016 film X-Men: Apocalypse. In 2009, the Sentinels were ranked by IGN as the 38th Greatest Comic Book Villain of All Time.

Publication history

The Sentinels first appeared in The X-Men #14 (November 1965), and were created by writer Stan Lee and artist/co-writer Jack Kirby.

Sentinels are programmed to locate mutants and capture or kill them. Though several types of Sentinels have been introduced, the typical Sentinel is three stories tall and is capable of flight, projecting energy blasts, and detecting mutants.

Characteristics

Sentinels are designed to hunt mutants. While many are capable of tactical thought, only a handful are self-aware.

Sentinels are technologically advanced, and have exhibited a wide variety of abilities. They are armed (primarily with energy weapons and restraining devices), capable of flight, and can detect mutants at long range. They possess vast physical strength, and their bodies are highly resistant to damage. Some are able to alter their physical forms or re-assemble and reactivate themselves after they have been destroyed.

Some Sentinels can learn from their experiences, developing their defenses during an engagement. Several groups of Sentinels have been created or led by a single massive Sentinel called Master Mold. Some Sentinels are also equipped with an inconspicuous logic loop in case they should go rogue to convince them that they are mutants.

Types of Sentinels

  • Tri-Sentinel - A giant-sized, six-armed, three-faced combination of three Sentinels created by Loki. Life Foundation attempted to reprogram the Tri-Sentinel but as that attempt failed along with the fail-safe Spider-Man and Nova had to destroy the Tri-Sentinel.
  • Soviet Sentinels - Created by the Soviet Union and later purchased by Cuban government officials.
  • Super-Sentinels - Using Nano-Sentinel technology, Weapon Plus created artificially evolved superhumans. Three of the creations were chosen to form the mutant-hunting Super-Sentinels: Huntsman, Fantomex and Ultimaton, who were intended to be presented to the public as superheroes to make the extermination of mutantkind look "like a Saturday morning cartoon".
  • Colcord's Sentinels - Several Boxbots were created by Madison Jeffries (aka Box) to serve Weapon X.
  • Hardaway - A cyborg created at Camp Hayden who called himself a Bio-Sentinel.
  • Juston Seyfert's Sentinel: A rebuilt Sentinel that was reprogrammed to obey Juston Seyfert. In Avengers Arena, the Sentinel is destroyed and Juston apparently killed. Juston is later revealed to have been revived after his Sentinel infused his body with nanotechnology, transforming him into a Sentinel cyborg.
  • Sentinaughts - One of the types of sentient robots who live in the free robot city of The Core, Sentinaughts are apparently based on the Sentinel design. They vary in size from roughly human to the large stature of traditional Sentinels.
  • Nano-Sentinel - Microscopic Sentinel type of tech created by Cassandra Nova and implemented in various ways by other users. They attach themselves to the brains of humans and mutants alike.
  • Adamantium Cyborgs - Near-fully mechanical mutant hunter killers refitted by Weapon X with the titular metal as an endoskeleton using sentinel based nanotech. Coming in numerous alphabetical categorical batches, these bionic weapons can shed their skin revealing a murderous automaton with the abilities of various X-Men heroes and villains integrated into them.
  • Core/Central Command - A biotech Master Mold variant behind the design parameters of the new Prime Sentinels.
  • Box Sentinels - Smaller and faster Sentinels based on the Box technology created by a joint venture between Department H and Orchis to track down and capture mutants in Canada.

Film

  • A Sentinel appears in X-Men: The Last Stand (2006) as a Danger Room simulation.
  • Two variations of the Sentinels appear in X-Men: Days of Future Past (2014). The prototype Mark I Sentinels were designed by Legacy Effects with Digital Domain building digital models based on a full-scale practical model while the future Mark X variants, based on Nimrod Sentinels, were computer graphics made by Moving Picture Company. In the film, the prototypes are said to be built using space-age polymers and are equipped with chest-mounted vent-like structures that grant flight capabilities as well as arm-mounted Gatling guns while the future Sentinels are smaller, sleeker, and built with adaptive mechanical scales, hands that can reform into blades, and emitters in their heads capable of firing energy beams. This version of the Sentinel program was originally created in the 1970s, with Bolivar Trask experimenting on mutants to accelerate his research, though he found little success in gaining support for his project. After Raven assassinated Trask in 1973 (which was the first time she killed and how she truly became Mystique), the U.S. government approved the Sentinel program, captured her, and experimented on her to give the Sentinels the ability to adapt to and utilize any mutant power. However, the Sentinels subsequently target humans due to their potential for having mutant descendants, culminating in a dystopian future where most of humanity and mutant-kind are nearly extinct by 2023. After Kitty Pryde uses her ability to project the minds of others into their past selves on Logan to rally Charles Xavier and Erik Lehnsherr's younger selves and avert Trask's assassination, the pair eventually succeed, causing the U.S. government to realize that not all mutants are a threat to humanity and abandon the Sentinel program.
  • The Sentinels make a cameo appearance in X-Men: Apocalypse (2016) as Danger Room simulations.
  • Sentinels appear in films set in the Marvel Cinematic Universe (MCU).
