Template:Infobox comics elements In the Marvel Comics universe, Cerebro (Spanish and Portuguese for "brain") is a device that the X-Men (in particular, their leader, Professor Charles Xavier) use to detect mutants. It was created by Xavier, and was later enhanced by Dr. Henry McCoy. The current version of Cerebro is called Cerebra, to be distinguished from the character of the same name. Cerebro first appeared in X-Men Volume 1 #7 (1964).

Use and function of the deviceEdit

Cerebro amplifies the brainwaves of the user. In the case of telepaths, it enables the user to detect traces of other mutants worldwide. Depictions of its inherent strength have been inconsistent; at times in the storylines it could detect mutated aliens outside of the planet, when at others it could only scan for mutants' signatures in the United States. It is not clear whether it finds mutants by the power signature they send out when they use their powers or by the presence of the X-gene in their body; both methods have been used throughout the comics.

Using Cerebro can be extremely dangerous, and telepaths without well-trained, disciplined minds put themselves at great risk when attempting to use it. This is due to the psychic feedback that users experience when operating Cerebro. As the device greatly enhances natural psychic ability, users who are unprepared for the sheer enormity of this increased psychic input can be quickly and easily overwhelmed, resulting in insanity, coma, permanent brain damage or even death. The one exception has been Magneto, who has been said to have minor or latent telepathic abilities as well as experience amplifying his mental powers with mechanical devices of his own design. Kitty Pryde once upgraded Cerebro so that non-telepaths could use the device. This was during the time that Professor Xavier was with the Shi'ar and Rachel Summers had just left the team. Kitty was able to track Nightcrawler who became missing after a battle with Nimrod.

The only characters to use Cerebro on a frequent basis are Professor X, Jean Grey, Emma Frost and the Stepford Cuckoos. However, Rachel Summers and Psylocke have also used it. After the device was upgraded to Cerebra, Cassandra Nova used it in order to exchange minds with Xavier. The Stepford Cuckoos once utilized the machine to amplify their combined ability, with only one of them directly connected to the machine, but all of them experiencing its interaction due to their psychic rapport. The strain of mentally halting a riot during Open Day killed Sophie, the Stepford Cuckoo who was hooked up to Cerebra. Sophie was both inexperienced at using Cerebra and was high on the mutant-enhancing drug "Kick"; however, it was revealed that it wasn't the strain of using the machine, nor the drug, that was responsible for her death, but Sophie's own sister Esme, whom also used Kick to power her own abilities, seize control of the Cuckoos temporarily, and manipulate Sophie into her death. The now remaining three Cuckoos demonstrated that they were capable of using Cerebra with relative ease in Phoenix: Endsong.

Some mutants have learned to shield themselves from Cerebro, usually via their own telepathic ability. Magneto can shield himself from the device through use of minimal telepathic powers; in the film series, he does so with a specially constructed helmet.

History of the deviceEdit

Originally, Cerebro was a device similar to a computer that was built into a desk in Xavier's office. This early version of Cerebro operated on punch cards, and did not require a user (telepathic or otherwise) to interface with it. A prototype version of Cerebro named Cyberno was used by Xavier to track down Cyclops in the "Origins of the X-Men" back-up story in X-Men Volume 1 #40. In the first published appearance of Cerebro, X-Men Volume 1 #7, Professor X left the X-Men on a secret mission (to find Lucifer) and left Cerebro to the new team leader, Cyclops, who used it to keep track of known evil mutants and to find new evil mutants. The device also warned the X-Men of the impending threat posed by the non-mutant Juggernaut prior to that character's first appearance. Later, the device was upgraded to the larger and more familiar telepathy-based technology with its interface helmet.

When the human-Sentinel gestalt Bastion stole Cerebro from the X-Mansion, Cerebro was hybridized with Bastion's programming via nanotechnology. The resulting entity, a self-aware form of Cerebro, created two minions, Cerebrites Alpha and Beta, through which it would act without exposing itself. It also used its Danger Room-derived records of the powers of the X-Men and the Brotherhood of Evil Mutants to create its own team of imposter "X-Men" whose members possessed the combined powers of specific members of each of the two teams. Cerebro's goal was to put human beings in stasis so that mutants could inherit the Earth, and to this end it hunted down a group of synthetic children called the Mannites who possessed vast psychic powers. It was destroyed by the X-Men, with the help of Professor X and the Mannite named Nina. More recently, following the example set by the X-Men films, Cerebro has been replaced by Cerebra (referred to as Cerebro's big sister), a machine the size of a small room in the basement of Xavier's School For Higher Learning. Though designed to resemble the movie version of Cerebro, Cerebra is much smaller than the films' version. It resembles a pod filled with a sparkling fog that condenses into representations of mental images.

Other versionsEdit

In Chris Claremont's X-Men: The End storyline, which takes place some 20 years ahead of standard X-Men continuity, Cerebra has been replaced in turn by the disembodied brain of Martha Johansson, a human psychic who was introduced during Grant Morrison's run on the X-Men.

In the video game X-Men Legends, Cerebro is identical to its appearance and usage in the X-Men film. Jean Grey and Emma Frost use the device at one point to attempt to return Professor X's mind to his body. In X-Men Legends II: Rise of Apocalypse, it was destroyed along with the rest of the mansion, but Forge mentioned plans on building Cerebra to replace it.

In the video game Marvel: Ultimate Alliance, while the team is staying in the Sanctum Sanctorum, Professor X used a device created by Beast allowing him to use Cerebro from long distance in order to find Nightcrawler, who had been kidnapped by Dr. Doom.

In the universe of Marvel Zombies, zombified versions of Beast and Mr. Fantastic reprogram Cerebro to help them and the other zombies track down the last remaining humans on Earth. Cerebro locates many in the European nation of Latveria, but all escape.

In the MC2 universe, the X-People carry "mini-cerebros", that can detect mutants just as well as the full-size version.

In other mediaEdit



In the films X-Men and X2: X-Men United, Cerebro is a massive device that fills a spherical room in the basement of Xavier's School. The helmet interface is similar to the version seen in the comics, although the bulk of Cerebro's machinery is contained in the surrounding walls. While in use, three-dimensional images of the minds scanned by the device appear around the user. Unlike the comics' version of Cerebro, the film version can detect both human and mutant minds with ease. The unique signature of mutant brainwaves is shown in the first film by having human mental images portrayed in black and white, while those of mutants show up in color; In X2, mutants appear in red, and humans in white.

In the first film, Cerebro is sabotaged by Mystique so that it injures Professor X, putting him into a coma. The only person seen using Cerebro effectively in the films is Xavier; Jean Grey attempted to use the device to locate Magneto in X1, but the input overwhelmed her nascent telepathic power and left her stunned, though she was successful. It is mentioned that Magneto helped Charles Xavier design Cerebro. This has not been confirmed to be true in the comics, although the Magneto of the comics can use Cerebro and has designed similar devices.

In X2: X-Men United, the device was copied and modified by William Stryker in his plot to have a brainwashed Xavier use his Cerebro-amplified powers to kill the world's mutants, and was later further modified by Magneto to kill humans. According to X2, it is difficult to pinpoint the location of mutants who have the ability to teleport and are constantly in transit, such as Nightcrawler.


In the X-Men: The Animated Series Cerebro was heavily featured throughout the series' duration. It was primarily used by Professor Xavier and he was shown to use it in various ways, such as detecting mutants, increasing his powers, and even understanding Shi'ar technology, and so forth. There was no specified room where Cerebro was kept as in the other animated series (which were all inspired by the designs in the X-Men films) but instead came out from the ceiling in most notably the War Room where the X-Men held their team meetings. Jean Grey was also noted to use Cerebro frequently and it would amplify her telepathic powers as it did for Professor X. Jean Grey in this animated series did not always join the X-Men on their field missions but rather monitored them telepathically using Cerebro's help. Even the White Queen of the Hellfire Club, Emma Frost, used Cerebro when she telepathically hacked into it to secretly "spy" on Xavier, the X-Men, and to learn more about Jean Grey and her transformation into the Phoenix. It should be noted that the X-Men's Blackbird jet was also equipped with its own Cerebro.

In the animated series X-Men: Evolution, Cerebro was featured numerous times. It was shown being used mainly by the Professor and eventually Jean Grey. In the beginning of the series Cerebro was a primitive version of what it would later become as the show progressed eventually taking an appearance identical to the Cerebro in the X-Men films. Cerebro originally appeared as a computer console with custom peripherals that came out of a hidden wall component in the mansion. Eventually this Cerebro was destroyed by Professor X's evil step-brother the Juggernaut. When it was rebuilt the Cerebro was given its own room, instead of the hidden wall component as before, and looked identical to the designs of Cerebro in the films. Cerebro even came in a portable helmet form for travel and field missions. Jean Grey used this Cerebro to amplify her telepathic powers as she did in the comics and previous series. It even helped boost Jean's telekinetic powers in order to battle a possessed Professor X in the series finale. During the fight Cerebro was shown to unleash the Phoenix within Jean for a split second, eventually gaining the power to defeat the evil Xavier eventually saving him. Telepaths were not the only ones who could use Cerebro in the series. In one episode the young Arcade, a student version of one of the X-Men greatest villains, hacked into Cerebro and used it to control the mansion's security system to attack the X-Men.

In the 1996 Generation X telefilm on Fox, Cerebro was depicted as a desktop personal computer with a few custom peripherals. The scaled down depiction fit with the very low budget appearance of the movie in general.

In the 2008 series, Wolverine and the X-Men, Cerebro is extremely important to the overall series as it serves as a link to the past, present, and future. Originally Cerebro was damaged in an unexplained attack on Professor X in the present where he ends up in a coma only to awake twenty years into the future. In the future twenty years from now the X-Men have all been killed and the world is being controlled by the mutant-hunting robots named Sentinels. With the surviving Cerebro components he finds Xavier telepathically contacts the X-Men twenty years in the past (the present) and instructs them to stop those who would create the bleak future he awakes in twenty years later (his present). During the majority of the X-men's present, as well as it's first appearances in the future, it is similar to the version seen in the X-men films, however for the majority of the scenes in the future, Xavier uses a Portable version of Cerebro. With Warren Worthington's money and Forge's technical expertise, the X-Men were able to get the Cerebro destroyed at the mansion repaired. As Xavier is comatose in the present and Jean Grey missing, Emma Frost serves as the team's resident telepath and she primarily uses Cerebro.
