The Sentinels are a group of mutant-hunting robots appearing in American comic books published by Marvel Comics. They are typically depicted as antagonists to the X-Men.

The Sentinels played a large role in the 1990s X-Men animated series and have been featured in several X-Men video games. The Sentinels are featured prominently in the 2014 film X-Men: Days of Future Past while simulated versions 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 as IGN's 38th Greatest Comic Book Villain of All Time.^[2]

Publication history

Created by Stan Lee and Jack Kirby, they first appeared in The X-Men #14 (Nov. 1965).^[3]

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, is capable of flight, projects energy blasts, and can detect mutants.^[4] Pursuing genocide as the means of dealing with a threat has made the Sentinels an analogy for racial hatred and other negative types of fanaticism in Marvel stories,^[5] represent the horrific consequences of humanity's actions based on hate and ignorance, along with a caution of the risks of AI takeover.

Characteristics

This section needs expansion. You can help by adding to it. (January 2011)

Sentinels are designed to hunt mutants.^[6] 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.^[6] Some are able to alter their physical forms or re-assemble and reactivate themselves after they have been destroyed.

Some Sentinel variants have the ability to 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.

Because of their power, sophistication, and high mass production, Sentinels are sold on the black market.^[7] Entities obtain them—often in poor condition—for their own purposes (not necessarily mutant-related).^[6][8]

Types of Sentinels

This section contains a list of miscellaneous information. Please relocate any relevant information into other sections or articles. (July 2018)

There are different types of Sentinels that appear in the comics:

• Mark I and Master Mold - Created by Bolivar Trask. First appeared in X-Men #14. Trask sacrificed himself to destroy the Master Mold.
• Mark II - Created by
  Larry Trask
  . This model was capable of adapting to and counteracting superpowers almost instantly. First appeared in X-Men #57.
  • No.2, the robotic leader of Larry's Sentinels, later "mutated" with the capability of creating space warps.^[10]
• Composite - Created by merging the remaining portions of five Sentinels destroyed by the X-Men and came under control of Ashley Martin. It rebelled against her and was subsequently destroyed.
• Mark III - Created by
  Edward Buckman and the Council of the Chosen
  . Based on incomplete notes of Trask and inferior to Mark II. First appeared in X-Men #98.
  • X-Sentinels - Created by Stephen Lang. They are androids who were duplicates of the original X-Men. First appeared in X-Men #99.
• Mark IV - Created by
  Sebastian Shaw
  . First appeared in The Uncanny X-Men #151.
• Mark V - Created by Shaw for U.S. government's Project Wideawake. First appeared in The New Mutants #2.
• Mark VI - Created by Shaw Industries for Project Wideawake and used by Onslaught. Also incorporated parts of Project Nimrod.
• Mark VII - Created by Shaw Industries. They were experimental and remote controlled.
• Nimrod (later Bastion) - A prototype Super Sentinel that arrived from the "Days of Future Past" timeline and was later reactivated by Reverend William Stryker.
  • Project Nimrod - Created by an offshoot of Project Wideawake and was in the experimental stage, Project Nimrod was actually a self-awareness program that Nimrod implanted before its demise into the base's military computer cybernet, the program served as a sleeper virus that awaited the opportunity to access a Sentinel development program so it could use it to re-create Nimrod itself. Cancelled after X-Force interfered.

• Prime Sentinels - Created by Bastion and Operation: Zero Tolerance. They were at first disabled humans infected with Nano-Sentinel technology at Prospero Clinic under the believe that they were being equipped with cybernetic nanotech implants to replace their lost limbs. Unbeknownst to many of them, they became sleeper agents for Operation: Zero Tolerance, as they would, upon activation by a mutant attack or near the presence of one, transformed into armored beings with powerful weapons systems.
  • Omega Prime Sentinels - The second generation of Prime Sentinels. Often simply called Omega Sentinels, their nanotechnology is far afield's in advancement to their brethren. Omega's have an 8 step cycle of transformation they undergo before transmuting from full organic to complete machine entities; which are Infection, Nesting, Replication, Dormancy, Activation, Union, Adaptation and finally Omega.^[11] Karima Shapandar is one of them.
• Wild Sentinels - Built in secret by Master Mold in Ecuador, activated by Donald Trask III and used by Cassandra Nova. New units are produced based on the currently available resources – salvaged parts, weapons and sometimes even entire vehicles – which give this particular type of Sentinel a very diverse, rag-tag appearance. Due to both this and their design flexibility, a wide variety of different shapes and forms have been observed. The Mega-Sentinels used to destroy Genosha and Nanosentinels both belong to this kind of Sentinel. The technology used in Nano-Sentinels is also employed by Weapon Plus for their artificial evolution experiments and the creation of their Super-Sentinels.
• Mark VIII - Sentinel Squad
  O*N*E, designed by Stark Enterprises
  . Unlike other Sentinels, the Mark VIII requires a human pilot.
  • T.O. Sentinels - An intended upgrade to the Squad O*N*E sentinels conceived of by director Robert Callahan, who sought to use techno-organic substance to increase the effectiveness of his Sentinel program.[12] Failing in his first attempt he would get a second chance after obtaining the Warlock infected New Mutants to use as experimental fodder for further technoforming augmentation to his Sentinel Squad Armor unit.^[13][14]
• Bio-Sentinels - Human mutant corpse infected by a technological virus created by Kaga.^[15] They come with the innate capacity of weaponizing bio-technological apparati such as Brood designed missiles as a means of offense.^[16]
• Stark Sentinels MK I - The Stark Sentinels debuted during the AXIS storyline. Under the influence of the Red Skull (who also had erased from him any memory of their construction), Tony Stark created a model of Adamantium constructed Sentinels outfitted with Pym Particle technology with databases withholding knowledge of different super heroes he acquired after the 1st Civil War storyline.^[17] When Red Skull became the Red Onslaught, and the Avengers arrived to Genosha to stop him, he deployed the Stark Sentinels.^[18]
• Mother Mold - A self-aware and capable of adaptation Master Mold variant head designed to create "Master Molds" which in turn create Sentinels. Built in secrecy near the Sun by a human group called Project ORCHIS which is made up of various members of human organizations such as A.I.M., S.H.I.E.L.D., Hydra, Alpha Flight and others, once coming online, Mother Mold will lead directly to the creation of Nimrod, the ultimate nanotechnological Sentinel form.^[19]
  • Nimrod the Hunter - Created in the modern era solely from contemporary technology and independent of its time-travelling counterparts by Dr. Alia Gregor on Orchis's Mother Mold
• X-Sentinels -
  Orchis' new era of Sentinel, which is a modern Sentinel created by Mister Sinister's clone Doctor Stasis. He pulled this off by building over his gene-spliced animal/human Chimeras and used the many corpses of Wolverine to perfect a process and converting them into Sentinel units, combining Wolverine's Adamantium skeleton and claws with the latest Sentinel casing and systems prove to be a lethal combination.^[20]
  • Sentinel Zero - The first X-Sentinel to come online and built over the frame of Wolverine's Adamantium Skeleton. In the end, Firestar incinerated Sentinel Zero's Sentinel parts, leaving a smoking Wolverine skeleton.
• Stark Sentinel MK II - A new version of Stark Sentinel created by the anti-mutant industrialist Feilong afer he embedded himself in the Stark Unlimited company and secretly funneled its resources in the construction of Sentinels based on the technology of the Iron Man Armor. Once Feilong publicly took control of the company, Iron Man investigated his movements and found out the first Stark Sentinel in the final process of assembly. Feilong had the robot come online to chase off Stark and herald his plans for mutantkind.[21]
