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 was ranked as IGN's 38th Greatest Comic Book Villain of All Time.

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.
This section needs expansion. You can help by adding to it. (January 2011)
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 Sentinel variants have the ability to learn from their experiences, developing their defenses during an engagement. Several groups of Sentinels have been created and/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 as demonstrated in the Tri-Sentinel.
- Mark I and Master Mold - Created by Bolivar Trask. First appeared in X-Men (vol. 1) #14. Bolivar 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 (vol. 1) #57.
- Composite - Created by merging the remaining portions of five Sentinels destroyed by the X-Men and came under control of Ashley Martin. It was destroyed by her when it rebelled against her.
- Mark III - Created by Stephen Lang and Project: Armageddon, secretly funded by Edward Buckman and the Council of the Chosen. First appeared in X-Men (vol. 1) #98.
- X-Sentinels - Created by Stephen Lang. They are androids who were duplicates of the original X-Men.
- Mark IV - Created by Sebastian Shaw. First appeared in X-Men (vol. 1) #151.
- Mark V - Created by Sebastian Shaw for U.S. government's Project Wideawake. First appeared in New Mutants (vol. 1) #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. Cancelled after X-Force interfered. Based on the Nimrod Sentinel.
- Prime Sentinels - Created by Bastion and Operation: Zero Tolerance. They are disabled humans equipped with nanotechnology without their knowledge at Prospero Clinic. The Prime Sentinels were used as sleeper agents until activated by attack or presence of a mutant.
- Omega Prime Sentinels - The second generation of Prime Sentinels. Karima Shapandar is one of them.
- Wild Sentinels - Built in secret by a new 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.
- Bio-Sentinels - Humans infected by a technological virus created by Simon Trask, the victims become anti-mutant activists, who later at Trask's command, are fully transformed into robotic Sentinels mindlessly following Trask's commands.
- Stark Sentinels - 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 Sentinels based on the knowledge of different super heroes he acquired after the Civil War storyline. When Red Skull became the Red Onslaught, and the Avengers arrived to Genosha to stop him, he deployed the Stark Sentinels.

- Tri-Sentinel - A combination of three fairly standard Sentinels bonded together by Loki, and defeated by Spider-Man at the peak of his cosmic (Captain Universe) powers. Later revived by The Life Foundation, only to be destroyed again by Spider-Man and Nova.
- 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 at The World. 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 in order to make the extermination of mutantkind look "like a Saturday morning cartoon".
- Colcord's Sentinels - Some of the Boxbots created by Madison Jeffries (aka Box) to serve the Weapon X Program, run by Malcolm Colcord. In one variation of the Days of Future Past timeline seen in the Weapon 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 the Mutant Liberation Front, who called himself a Bio-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, such as adapting to almost any situation and programming that at times forced him to attack mutants.
- Juston Seyfert's Sentinel: First appearing in Sentinel #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 of Avengers Academy and featured in Avengers Arena.
- 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.
The following are alternative versions of the Sentinels, which appear outside of regular Marvel canon.
Age of Apocalypse
In the "Age of Apocalypse" timeline, Bolivar Trask created the Sentinels with his wife Moira. These Sentinels are equipped with several body-mounted gun turrets, and their primary directive is to protect humans rather than to hunt mutants. They are capable of cooperating with mutants in order to further this mission. Later the Sentinels are adapted by Weapon Omega to serve a reverse purpose, and now aid in the hunting of the human race.
Days of Future Past
In the "Days of Future Past" timeline, which takes place in an alternate future, the "Omega Sentinels" have advanced technologically and become the de facto rulers of the United States. The most powerful among them is Nimrod.[volume & issue needed]
Here Comes Tomorrow
In the "Here Comes Tomorrow" future timeline, a Sentinel named Rover is Tom 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]
House of M
In the House of M storyline, Magneto is victorious in a mutant/human war. The Sentinels are adapted by Sebastian Shaw, now the director of S.H.I.E.L.D., to serve a reverse purpose, and now aid in the hunting of sapien rebels.[volume & issue needed]
In the alternate reality of X-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]
In the comic crossover X-Men/Star Trek: Second Contact, the X-Men work with the crew of the Enterprise-E to battle Kang the Conqueror. An away team composed of Captain Picard, Deanna Troi, Nightcrawler and Colossus encounter an approximation of the "Days of Future Past" timeline, in which the Sentinels have merged with the Borg.[volume & issue needed]
In Ultimate X-Men, the Sentinels, created by the Ultimate Marvel version of Bolivar Trask, were already in action at the beginning of the first 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 the New Sentinels that were sixty of S.H.I.E.L.D.'s top agents in Sentinel battle armor that was described as having enough hardware to take on a fleet of the old Sentinel models. A new breed of Sentinel robots, created by Trask under orders from the Fenris twins, was later created.
After the events of the Ultimatum Wave, a new model of Sentinel (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 the Shroud.
- In an issue of the What If series, Cannonball's brother Josh (who would, in normal continuity, later become Icarus) found and "adopted" a Sentinel.[volume & issue 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.[volume & issue 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.[volume & issue needed]
In other media
- A Sentinel appeared in Spider-Man and His Amazing Friends. In the episode "A Firestar Is Born", It is seen in a flashback, fighting the X-Men back when Firestar was a member.
- The Sentinels appeared a number of times on the X-Men animated series, voiced by David Fox. They appeared as season one's main antagonists. The Sentinels first hunt down Jubilee. The Sentinel program, controlled by Bolivar Trask and Henry Peter Gyrich, was cancelled but the project moved overseas to Genosha. Trask constructed Master Mold for the Sentinels while on Genosha, but it was apparently destroyed when Storm flooded the complex. Sentinels are later seen in Bishop's future timeline where they had taken over the world and mutants were on the verge of extinction. In the season one finale, the Sentinels, acting under Trask's orders, rescued Senator Robert Kelly from Magneto, but Master Mold then declared "giving the orders now" in Track's and Gyrich's secret base in the United States. As Master Mold plans to kidnap world leaders from around the world and replace their brains with computers so that the world would fall under his control, the X-Men managed to fight through a seemingly endless wave of Sentinels until Charles Xavier flew an explosive-filled Blackbird into Master Mold and escaped at the last minute with Magneto's help. However, the Sentinels had sporadic appearances in season four.
- The Sentinels appeared in Spider-Man: The Animated Series. In the episode "The Mutant Agenda", they are seen in a Danger Room simulation when Spider-Man accidentally activated the simulation when visiting the X-Mansion.
- The Sentinels appear in X-Men: Evolution. This version is much more powerful and heavily armed than their comic book counterparts. There was originally only a prototype created by former S.H.I.E.L.D. agent Bolivar Trask, however, released in public by Magneto to force the X-Men to fight the prototype and reveal mutant existence to the media. The prototype alone was a dangerous challenge, even for the combined might of the X-Men and the Brotherhood. Three upgraded Sentinels are later used by S.H.I.E.L.D. against Apocalypse and prove a difficult fight for the ancient mutant. The series finale hinted with Professor X's future visions at Nimrod appearing later in the show's timeline leading a fleet of Sentinels.
- Sentinels appear in the Wolverine and the X-Men animated series, voiced by Jim Ward. There are several types of Sentinels: Sentinel Prowler, the Mark I Sentinel, a more futuristic Sentinel, and Sentinel Hounds. The Sentinels are controlled by Master Mold.
- Sentinels appear in The Super Hero Squad Show, voiced by Tom Kenny. In this version, they were created in an alternate reality's future where they were created to defend a superhero-less city. They are seen in the episode "Days, Nights and Weekends of Future Past! (Six Against Infinity Part 2)".
- A Sentinel appeared in a Danger Room simulation in Marvel Anime: X-Men.
- A Sentinel appears in the Ultimate Spider-Man animated series. In the episode "Game Over", Arcade's Madland game includes a real Sentinel (in the Days of Future Past level) which Spider-Man took control of, using its firepower to cheat through Arcade's levels.
- A Sentinel appears in the Toei anime series Marvel Disk Wars: The Avengers.
- The Gifted television series, which is connected to the X-Men cinematic universe, features a modern-day version of the Sentinels called Sentinel Services. In the seventh episode "eXtreme measures" Trask Industries (the creator of the Sentinels) is revealed to have been responsible for the Hound Program.
- Sentinels appeared in an early draft of X-Men (2000), wherein Henry Peter Gyrich and Bolivar Trask attacked the X-Men with the Sentinels, but this treatment didn't make it past the concept stage.
- Sentinels were planned for inclusion in X2: X-Men United (2003), but they did not appear onscreen (although Project Wideawake is mentioned on a computer readout screen). Sketches for the Sentinels appear as extras on the DVD release. The Sentinels' height was not specified, but the sketches indicated that although their appearance was not severely altered, they would have had the ability to compact itself into a rolling saucer as a mode of transportation.
- A Sentinel was seen in X-Men: The Last Stand (2006), during a training simulation for the young mutants at Xavier's school. At the end of the session, Colossus throws Wolverine at the robot, while the latter beheads it. The only part of the Sentinel ever made visible to the viewer is its severed head, while the rest is shrouded in fog.
- The Sentinels are featured in X-Men: Days of Future Past (2014) as secondary threat to the mutants. In 1973, Bolivar Trask pitches the Sentinel concept to the US Congress but they decline him so he pitches them to foreign powers. Mystique kills Trask in revenge for the mutants' murders that were experimented on while creating the Sentinels. Inspired by the fear of Trask's death, the US government approves the Sentinel program to hunt and kill mutants, and research on Mystique leads to Sentinels that can adapt and use mutant powers. The Sentinels eventually expand their targets beyond mutants to baseline humans based on the logic that they have the potential to produce mutant descendants, culminating in a dystopian future where most of humanity and mutantkind have been wiped out. With Kitty Pryde having developed the ability to project the minds of others into their past selves, the X-Men project Wolverine - the only person capable of surviving the time-travel's psychological strain - back into his past self in 1973 to rally the younger versions of Charles Xavier and Beast to stop Trask's assassination, setting into motion the events of the film. The storyline concludes with Mystique defeating Magneto and then deciding not to kill Trask on Xavier's encouragement, resulting in the government witnessing clear evidence that not all mutants are a threat to normal humans and deciding to abandon the Sentinel program. The original Sentinels from 1973 were similar in appearance to their comic counterparts being three times the size of a human, possessed gatling guns on one of their arms capable of firing 3000 rounds per minute, sensors that allow them to track carriers of the X-Gene and could fly using the vent-like systems on their chest. They were built out of a space-age polymer to be immune to Magneto's powers (but the mutant infuses them with metal bars to control them in the film's climax). In contrast, the future Sentinels were smaller and sleeker, with a body built out of adaptive mechanical scales, and besides having Mystique's adaptive powers they can reshape their hands into stabbing blades. The Sentinels were designed by Legacy Effects with Digital Domain building digital models based on their full-scale practical model while the future variant were all computer graphics made by Moving Picture Company.
- The Sentinels appear at the end of X-Men: Apocalypse (2016), once again in a training simulation, where the new X-Men team begins their training.
Sentinels have appeared as major antagonists in almost every video game to feature the X-Men:
- In the X-Men arcade game, where they served as the bulk of enemies.
- In Spider-Man/X-Men: Arcade's Revenge, they were featured enemies in Cyclops' levels.
- In X-Men: Mutant Apocalypse, Sentinels appear as bosses in Genosha, with varying sizes.
- A robot resembling a Sentinel also appears in both the arcade and SNES versions of Captain America and the Avengers. In the game, it is not called a 'Sentinel', but instead, is referred to simply as 'Robot'.
- In X-Men 2: Clone Wars, in the second level (the first level after the title screen), Sentinels appear in the background, as the level is set in a high-tech factory that produces Sentinels.
- A non-standard 10' tall Sentinel is a playable character in X-Men: Children of the Atom.

- In X-Men: Next Dimension, Bastion is the main boss character, who is also unlockable as a playable character. A male Prime Sentinel and a female Prime Sentinel are both available as playable characters.
- In X-Men Legends, they are the game's primary antagonists. There are several versions of the Sentinels in this game:
- Sentinel Alpha uses rockets, gas, stomp, and a palm beam
- A Sentinel with rockets, eye beams, stomp, and a bomb (this version has shoulder pads like Sentinel Squad ONE)
- A Sentinel Controller with eye beams, stomp, an enhanced version of the palm beam, rockets, and a wave that nullifies mutant powers (this version has a blue head and its body is blue and purple)
- A Sentinel Weapons Platform in the shape of a purple spider with green blasters, which can bash and use a green wave that reverses the controls
- A Sentinel Advanced (based on the Prime Sentinel) with freeze beam, orange blasters, punch, groundquake (with fist), and a rush.
- In X-Men Legends II: Rise of Apocalypse, the Sentinels are shown assisting with the evacuation after Apocalypse devastates New York City. Bastion later turns them on the X-Men and the Brotherhood of Mutants. After Bastion is defeated, the Sentinels resume their evacuation duties.
- In X-Men: The Official Game (which fills the gap between X2 and X-Men: The Last Stand), the Sentinels are part of William Stryker's back-up plan if his plan to eliminate all mutants with the Dark Cerebro failed. Stryker would have the mutant-hunting robots track down and kill all mutants they could find. The Sentinels featured in the game appear to be similar to those from the game X-Men: Children of the Atom. There are two types of Sentinels: one is a smaller, aerial model; and the other is a giant walking behemoth.
- In the X-Men Origins: Wolverine video game, the Sentinel Mark I is one of the major bosses of the game. While infiltrating the headquarters of Project Wideawake to find his old teammate John Wraith, Wolverine encounters two full-sized Sentinels, destroying a half-finished Sentinel with a Sentinel hand-weapon and defeating the other one in a prolonged confrontation.
- The Sentinel from X-Men: Children of the Atom (now given the model number "COTA-94", in reference to the year Children of the Atom was released) is an unlockable playable character in Marvel vs. Capcom 3: Fate of Two Worlds and its updated version Ultimate Marvel vs Capcom 3, with Jim Ward reprising his role.

Several different toys of Sentinels have been made since their introduction. One is the X-Men Classics 10" Sentinel by Toybiz. A "Build-A-Figure" version of the character was made in wave ten of the Marvel Legends line. The most recent Sentinel toy is made by Hasbro as part of the Marvel Universe line. Along with a large, unposeable statue, two Minimates figures have been made of the Sentinels. The first, a classic version, came with Rachel Summers in either her Phoenix or Marvel Girl guises. The second, based on Marvel vs. Capcom 3: Fate of Two Worlds, comes with a red-haired "First Appearance" figure of Ryu. In 2014, The Lego group released a set in the Marvel Super Heroes line titled "X-Men vs. the Sentinel", featuring the sentinel as a buildable figure, also including the Blackbird, Magneto, Wolverine, Storm, and Cyclops.
- On the Adult Swim show Robot Chicken, the episode "Sausage Fest" showed a parody of the X-Men being killed by a Sentinel, and Professor X then recruiting the cast of the Police Academy films to replace them.
