The Sentinels played a large role in severalX-Men animated series, and have been featured in severalX-Menvideo games. The Sentinels are featured prominently in the 2014 filmX-Men: Days of Future Past, and made brief appearances in the 2006 filmX-Men: The Last Stand and the 2016 filmX-Men: Apocalypse. In 2009, The Sentinels were ranked inIGN as the 38th Greatest Comic Book Villain of All Time.[2]
Sentinels are programmed to locatemutants and capture or kill them. Though several types of Sentinels have been introduced, the typical Sentinel is threestories tall, is capable offlight, 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 offanaticism in Marvel stories,[5] represent the horrific consequences of humanity's actions based on hate and ignorance, along with a caution of the risks ofAI takeover.
Sentinels are technologically advanced, and have exhibited a wide variety of abilities. They are armed (primarily withenergy 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 calledMaster 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]
There are different types of Sentinels that appear in the comics:
Mark I andMaster Mold - Created byBolivar Trask. First appeared inX-Men #14. Trask sacrificed himself to destroy the Master Mold.
Mark II - Created byLarry Trask. This model was capable of adapting to and counteracting superpowers almost instantly. First appeared inX-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 byStephen Lang and Project: Armageddon, secretly funded byEdward Buckman and theCouncil of the Chosen. Based on incomplete notes of Trask and inferior to Mark II. First appeared inX-Men #98.
X-Sentinels - Created by Stephen Lang. They areandroids who were duplicates of the original X-Men. First appeared inX-Men #99.
Mark IV - Created bySebastian Shaw. First appeared inThe Uncanny X-Men #151.
Mark V - Created by Shaw for U.S. government'sProject Wideawake. First appeared inThe New Mutants #2.
Mark VI - Created by Shaw Industries for Project Wideawake and used byOnslaught. Also incorporated parts of Project Nimrod.
Mark VII - Created by Shaw Industries. They were experimental and remote controlled.
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 afterX-Force interfered.
Prime Sentinels -Bastion's humanoid Sentinels. They were at first disabled humans infected with Nano-Sentinel technology at Prospero Clinic under the belief that they were being equipped with cybernetic nanotech implants to replace their lost limbs. Unbeknownst to many of them, they became sleeper agents forOperation: Zero Tolerance, as they would, upon activation by a mutant attack or near the presence of one, transformed into armoredcyborg 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.
Mark VIII /Sentinel SquadO*N*E - Sentinels designed byStark Enterprises which, unlike other Sentinels, 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 the 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 the 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 theAXIS storyline. Under the influence of theRed Skull (who also had erased from him any memory of their construction),Tony Stark created a model ofAdamantium-constructed Sentinels outfitted with Pym Particle technology with databases withholding knowledge of different super heroes he acquired after the 1stCivil 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 - 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 byMister 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.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 after 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]
Fireteam - A group of cyborg sentinels created by Larry Trask from the harvested nanites inside Juston Seyfert, to create human sentinels of his own. This led to the creation of a new Sentinel Program which he uses to track down and capture the world's most dangerous mutants.

Colcord's Sentinels - Some of the Boxbots created byMadison Jeffries (aka Box) to serve theWeapon X Program, run byMalcolm Colcord. In one variation of theDays of Future Past timeline seen in theWeapon X: Days of Future Now limited series, one of the Boxbots evolves into a new Master Mold and a new breed of Sentinels.
Hardaway - A cyborg created at Camp Hayden, killed by theMutant Liberation Front, who called himself aBio-Sentinel.
X-51 (Machine Man) - Captured by Bastion and "infected" with Prime Sentinel nano-bots which reconfigured and reconstructed his systems thereby giving him similar capabilities to Nimrod,[24][25] such as adapting to almost any situation and programming that at times forced him to attack mutants.[26]
Juston Seyfert's Sentinel: First appearing inSentinel #1, this is a rebuilt Sentinel (likely a Mark V or Mark VI), reprogrammed to obey Juston Seyfert. Initially, Seyfert controlled the Sentinel by riding on its shoulder; he now has built a cockpit into it. Seyfert and his Sentinel are former members ofAvengers Academy and featured inAvengers Arena.
Sentinaughts - One of the types of sentient robots who live in the free robot city of The Core,[27][full citation needed] 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.[28] Moving within the body and attaching themselves to the brains of humans and mutants alike, turning them into mutant-hating assault drones with no self control. Ready to take down any mutant who so much as looks at them.[29]
An unknown form of human made Sentinels created by Simon Trask using a nanite based Sentinel Tech virus. The victims become anti-mutant activists who later, at Trask's command, are fully transformed into lifeless robotic Sentinels mindlessly following Trask's orders.[30]
Adamantium Cyborgs - Near-fully mechanical mutant hunter killers refitted by Weapon X with the titular metal as an endoskeleton using sentinel based nanotech.

Box Sentinels - Smaller and faster Sentinels based on theBox technology created by a joint venture betweenDepartment H and Orchis to track down and capture mutants in Canada.[33]
In theAge of Apocalypse timeline, Bolivar Trask created the Sentinels with his wifeMoira MacTaggert. These Sentinels are equipped with several body-mounted gun turrets, and their primary directive is to protect humans rather than to hunt mutants.[citation needed] They are capable of cooperating with mutants to further this mission.[34][full citation needed] Later, the Sentinels are adapted by Weapon Omega to serve a reverse purpose, and now aid in the hunting of the human race.[35][full citation needed]
In theDays of Future Past timeline, which takes place in an alternate future, the "Omega Sentinels" have advanced technologically and become thede facto rulers of theUnited States. The most powerful among them isNimrod.[volume & issue needed]
In theHere Comes Tomorrow future timeline, a Sentinel namedRover isTom Skylark's companion and protector. After more than 150 years of being active, Rover has become self-aware and, possibly, capable of emotion.[volume & issue needed]
In the alternate reality ofX-Men: Ronin, the story is played out in Japan. A police unit called "Sentinel Force" designs, builds and pilots the robots. These are aesthetically similar to regular Sentinels, but each is subtly different from the others.[volume & issue needed]
TheUltimate Marvel version of Sentinels were created by Bolivar Trask, were already in action in theUltimate X-Men story arc, hunting down and killing mutants on the streets, in a program apparently openly and publicly acknowledged by the U.S. government. Later on, there were also theNew Sentinels that were sixty of S.H.I.E.L.D.'s top agents in Sentinelbattle armor and they were described to have enough hardware to take on a fleet of the old Sentinel models. A new breed of Sentinel robots, created by Trask under theFenris twins' orders, was later created. After the events of theUltimatum Wave, Nimrod Sentinels was deployed to hunt, capture or kill mutants that refused to turn themselves in.William Stryker, Jr., using Sentinel tech, later displayed an ability to summon a fleet of Sentinels after being attacked by theShroud.[36][full citation needed]
InWhat If... StarringCannonball's little brother Josh—and his pet Sentinel", shows Josh (who would, in normal continuity, later becomeIcarus) finding and adopting a Sentinel.[37][full citation needed]
In "What if... Starring Secret Wars: 25 Years Later", the children of Marvel heroes are teleported back to Earth where, sometime in the last 25 years, a variation of "Days of Future Past" is shown when the group is attacked by Sentinels.[38][full citation needed]
In "What if... Starring Juggernaut: The Kingdom of Cain",Juggernaut has killed the X-Men, and as a result there is no one to oppose the Sentinels, so the world is ravaged by them until they are destroyed by Juggernaut.[39]
The Sentinels appear inX-Men: The Animated Series, voiced byDavid Fox.[40] Introduced in the first season, the Sentinel program was controlled byBolivar Trask andHenry Peter Gyrich and was temporarily cancelled before being transferred toGenosha, with Master Mold constructed as the Sentinels' leader/mass-production unit. While the Sentinels are seemingly destroyed byStorm, a possible future depicts them as having taken over the world and successfully putting mutants on the verge of extinction. In the first season finale, Master Mold takes over the Sentinels from Trask and Gyrich's secret U.S. facility in an attempt to kidnap world leaders and replace their brains with computers to bring them under its control, resulting inProfessor X andMagneto joining forces to thwart Master Mold. Afterwards, the Sentinels and Master Mold make sporadic minor appearances in the fourth season.
The Sentinels appear inX-Men: Evolution.[citation needed] These versions are more heavily armed than their comic book counterparts. In the episode "Day of Reckoning" Pt.1, Magento hijacks a prototype Sentinel to attack the X-Men and reveal mutant existence to the media. In "Uprising",S.H.I.E.L.D. uses three upgraded models againstApocalypse. Additionally, the series finale "Ascension" Pt. 2 features a vision of the future which includes a fleet of Sentinels led by Nimrod.
A Sentinel appears in theRobot Chicken episode "Sausage Fest".
The Sentinels appear inWolverine and the X-Men, voiced byJim Ward.[40] This version of the Sentinel program consists of Mark I Sentinels,Sentinel Prowlers, an unnamed futuristic variation from a Sentinel-dominated future, andSentinel Hounds, all controlled by Master Mold. Additionally, the reprogrammed SentinelRover appears in a self-titled episode as an associate of a future incarnation of the X-Men.
Alternate timeline variants of the Sentinels appear inThe Super Hero Squad Show episode "Days, Nights, and Weekends of Future Past! (Six Against Infinity Part 2)", voiced byTom Kenny.[40] These versions were created to defend Super Hero City in a possible future where theScarlet Witch is a dictator.
A variation of Sentinel Squad O*N*E appears in theAvengers Assemble four-part episode "Civil War". This version, established byUltron, consists of a mech-sized battlesuit and unmanned green and yellow sentries.
The Sentinels appear inThe Gifted.[41] These versions are small spider-like robots created by Trask Industries to withstand various hazardous environments and forms of attack as well as adapt quickly to damage taken. Additionally, a similarly named government agency calledSentinel Services appears throughout the series.
The Sentinels as they appear inX-Men: Days of Future Past (2014); theMark I model in 1973 (left) and theMark X model in 2023 (right)
The Sentinels were originally meant to appear inX-Men (2000). In an early draft written byAndrew Kevin Walker and turned in during June 1994,Henry Gyrich andBolivar Trask use three 8 feet (2.4 m) tall Sentinels to attack theX-Men.[45] Following several rewrites and new scripts, the Sentinels were eventually dropped from the film.[46]
Two variations of the Sentinels appear inX-Men: Days of Future Past (2014).[47][48][49][50] The prototypeMark I Sentinels were designed byLegacy Effects withDigital Domain building digital models based on a full-scale practical model while the futureMark X variants, based on Nimrod Sentinels,[48][50] were computer graphics made byMoving 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. AfterMystique assassinated Trask in 1973, the U.S. government approved the Sentinel program, captured Mystique, and experimented on the latter 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. AfterKitty Pryde uses her ability to project the minds of others into their past selves onLogan to rallyCharles Xavier andErik 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 inX-Men: Apocalypse (2016) as Danger Room simulations.
The Sentinels appear inX-Men: Next Dimension, with a male and female Prime Sentinel available as playable characters.
The Sentinels appear inX-Men Legends, voiced byScott MacDonald.[40] This version of the Sentinel program includes regular Sentinels, Sentinel Alpha, a Sentinel Controller, a Sentinel Weapons Platform, and a Sentinel Advanced.
A non-standard 10' tall Sentinel appears as an unlockable playable character inMarvel vs. Capcom 3: Fate of Two Worlds andUltimate Marvel vs Capcom 3, voiced again by Jim Ward. In its arcade mode ending, it uploads Master Mold's program intoGalactus's warship with the intention of killing mutants and humanity via Galactus-inspired Sentinels.
In 2020, Brooklyn rapper Magneto Dayo unveiled "The Sentinels", a project that gained viral traction on Instagram reels in 2024, amassing over 5 million plays.
