Neo-Sentinels 0001

They were later used by the Consortium after the destruction of the last of their Mark II Sentinels.

Sentinels (Earth-295) from Amazing X-Men Vol 1 1 0001

Earth-295 (Age of Apocalypse)

The Sentinels on Earth-295 were constructed by Bolivar Trask, a member of the Human High Council to defend humanity from the threat of Apocalypse. Early prototypes were manufactured in Africa and were sent to defend Wakanda from Apocalypse's genetic culling, leading to a clash with the X-Men in the process.[1] This model of Sentinel was human-sized and armed with palm-mounted blasters and rocket boots.

These human-sized models were later phased out for giant humanoid robots armed with laser cannons in their heads, and the ability to fire their gauntlets like rockets. They also contained rocket boots that allowed for flight. They acted as the primary defender of the Eurasian human settlements. They had a patrol route that circled the entire European continent and the northeastern region of Africa. Manufacturing plants where these Sentinels were created were speculated (though unconfirmed) to be located both at Muir Island, Scotland and the German colonies.[2]

A squad of Sentinels were dispatched by the Human High Council to perform a massive evacuation of remaining humans in North America. With the aid of Weapon X and Jean Grey, the Sentinels would breach Apocalypse's sea-wall defense perimeter.[3] Arriving on the shores of America, a squad of X-Men would be there to aid with the evacuation process, despite some interference by brought on by the Brotherhood of Chaos.[4] Their mission would be a success although they would unknowingly smuggle Copycat, Box and the Reavers into Europe.[5]

Following the downfall of Apocalypse,[6] the Sentinels were used by Weapon X in his quest to cull the human race, then used after his own fall by the Human Council.[7][citation needed]

Uncanny X-Men Vol 1 142

Earth-811 (Days of Future Past)

In Earth-811, the Omega Class Sentinels were the robotic controllers of the United States of America. Sentinel Mk VI was the previous model, and Nimrod was following the model. They were self-replicating robotic "overseers" of Earth and Mutant hunters. They were originally born in the Baxter Building, New York City, New York, Earth-811, and also other construction centers throughout the United States of Earth-811.

In the alternate reality of Earth-811 ("Days of Future Past"), the Brotherhood of Evil Mutants assassinated Senator Robert Kelly. As a result, anti-mutant hysteria grew and an extreme candidate was elected President. This President freed the Sentinels, giving them the open order to permanently eliminate the mutant "threat."

The Sentinels reacted by taking control of the United States and all of North America, and killing or capturing virtually all of the super humans, be they mutants or not. Captured mutants were kept in concentration camps known as "mutant internment centers."

The self-replicating Sentinels developed a new model, the Omega series, designed specifically to hunt and kill superhuman mutants. They share the most threatening feature of the Mark IIs, a learning program.

The Omega Sentinels, absolute kings of the land, later developed an even more advanced Sentinel: Nimrod. The prototype of this project managed to go to Earth-616.[8]

Powers included:

  • Darts: Omega Sentinels carried ten steel javelin-like darts on their trunks that could be thrown to pierce an opponent.
  • Electric Isolation: Omega Sentinels were specially protected and insulated against electrical attacks.
  • Encephalo-Scanner: At least some of the Omega Sentinels ("Executive type") were equipped with an scanner to read brainwaves of a target and determine if the target was being truthful. This device was not infallible.
  • Energy Blasts: The Mark I Sentinels had a variety of different blasts that could be shot from their chests, including plasma, electron, stun, and heat blasts. They were also armed with a disintegrator, although it only worked with inorganic matter.
  • Flight: Jets were used to stay aloft.
  • Learning Program: A special learning program allowed an individual Mark IV to attain certain advantages when fighting an enemy, but only after some seconds of analysis. This data could be stored for future uses against the same enemy, so that any model Sentinel could then access the information. Any needed modification would take at least one week. In the 21st century, all known mutants, living or dead, were filed in the program's database.
  • Mutant Detection: The Sentinels constantly scanned all the living beings in the immediate surrounding area and were able to determine if they were humans or mutants. The "immediate area" covered up to ten miles.
  • Robot: Due to their construction and fabrication materials, the Sentinels were protected by the sheer strength of their hulls. They could not be affected by emotional or mental attacks, nor by illusions, due to their robotic natures. However, they were susceptible to attacks affecting machinery.

Omega Sentinels were able to lift up to 70 tons.

The Mark I Sentinels were programmed to protect humanity from mutants, but their programming was completely open as for how they could accomplish this task. Thus, they could damage or kill humans to capture mutants.

The Sentinels

Earth-889 (Pre-digital Era)

After the Zeppelin accident[9] in which the confrontation between the alternate reality invasion scout Agent X-13 and Mr. Logan of the X-Society ended in a catastrophic explosion and the death of numerous civilians, the mutants accused to be responsible for the event were subsequently disowned and assigned to residence by the authorities, and threatened by mechanical men called Sentinels.

Sentinels 2099

During the fight between Victor von Doom and Erik Czerny traveling in time they found themselves in a time period where they observed the death of Wolverine by a Sentinel[10].


On Earth-1191, the Sentinels would take over the world much as they did on Earth-811, however this reality's mutants would eventually fight back and free themselves from slavery. Trevor Fitzroy would bring some of these Sentinels with him when he traveled back to present day Earth-616, where they would be used as part of his "game" with the Upstarts to slay Donald Pierce and the Reavers.[11] One such Sentinel would be damaged and become inundated with the bio-mechanical fluid that Pierce used to create his cyborgs and androids. When accidentally reactivated by Wolverine and Jubilee, this Sentinel would find that it had gained sentience and re-christen itself 3.14159. It would attempt to eradicate the Earth to make room for Sentinels to be the dominant life form on the planet and would reactivate Larry Trask's Mark II Sentinels to accomplish this goal. It would later scrap this plan while witnessing human compassion when battling Logan and Jubilee, and decided to try to understand and alter Sentinel programming to be able to articulate and express human compassion. This process, according to 3.14159 would take over 2137 years.[12]

In recent history, when humanity began to mutate due to the Terrigen Mists, the governments of the world did not know the cause and assumed that mutation was a communicable disease being spread by mutants. In order to try and stave off what the governments believed to be the cause of the infection, mutants and those who were "infected" were placed in internment camps.
