||This article describes a work or element of fiction in a primarily in-universe style. (October 2009)|
|First appearance||X-Men #5 (May 1964)|
|Created by||Stan Lee
|In story information|
Utopia is the name of the separatist mutant homeland created by the X-Men from the remains of Asteroid M which is the name of several fictional settings, each an asteroid converted by the mutant Magneto into his home/orbiting base, in the Marvel Comics Universe. Asteroid M was created by Stan Lee and Jack Kirby, in X-Men #5 (May 1964).
Asteroid M has been destroyed and reconstructed by the Master of Magnetism many times since it was first introduced. Each iteration has had several internal levels, including an observation deck, hangar bays and medical facilities. The various facilities have had technology that keep the asteroid concealed from standard detection technology. They have all been positioned in a low geosynchronous orbit. Each asteroid was relatively small yet sufficiently large that it could not be shot down, or destroyed externally, without the risk of massive devastation to Earth.
First version 
Magneto completes construction on Asteroid M just before recruiting his children, Quicksilver and the Scarlet Witch into his group, the Brotherhood of Mutants, as seen in X-Men, vol. 2 #-1 (July 1997). This first version is destroyed in a battle with the original team of X-Men in X-Men #5 (May 1964) after the Brotherhood kidnapped the Angel and held him prisoner there. The X-Men got there using a rocket that was being used to transport the Toad. This version has a device on it that can increase Magneto's magnetic powers.
Second version 
Asteroid M is reconstructed just after Magneto imprisons the X-Men in his Antarctic citadel, reducing them to the level of six-month-old babies, around the time of X-Men #113 (September 1978).
The space station is severely damaged when Warlock, an alien being from a techno-organic civilization with rigid rules and regulations, is fleeing to Earth. He collides with Asteroid M, breaking it to pieces, as seen in New Mutants, vol. 1 #21 (November 1984).
Third version 
During his brief association with the Hellfire Club, Magneto builds a fancier version of Asteroid M. Wanting a contingency plan if things don't work out with the Club, Magneto proceeds to rebuild his base of operations to survey the Earth from high above. From there, he hears of the troubles of his daughter, the Scarlet Witch. He descends to Earth to bring her back to his space station. This version was first seen in Avengers West Coast #57 (April 1990).
When the West Coast Avengers attack Asteroid M to free their team-mate, we learn that Magneto has service robots on the station. The service robots are instrumental in alerting Magneto to the presence of the Wasp on his base. Furthermore, we learn that the entire asteroid isn't made out of metallic objects. Quicksilver demonstrates this when he rips plastic tubing out of one the consoles.
After events involving Zaladane, in the Savage Land, Magneto returns to Asteroid M to live in peace, but his peace doesn't last very long. Acolytes, led originally by Fabian Cortez, request and are granted sanctuary by Magneto on Asteroid M, to escape American soldiers that are chasing them.
In X-Men, vol. 2 #1 (October 1991), it is stated that the asteroid is in geosynchronous orbit and 250 kilometers above the Earth. The asteroid also has selective inhibitor fields that may keep mutants or superhumans from using their powers. This version of the asteroid has medical and science facilities, an observation deck, sleeping quarters, and a swimming pool.
This third version of Asteroid M is destroyed in X-Men, vol. 2 #3 (December 1991). From an escape pod, Cortez sets off nuclear missiles that were around the asteroid. Although Magneto survives the re-entry of Asteroid M to Earth, the rest of the original Acolytes do not. The remains of this Asteroid M crash in the Middle East. Forge, Henry Peter Gyrich, and other government officials, inspect the wreckage in Uncanny X-Men #299 (April 1993).
Fourth version 
Fifth version/Utopia

|First appearance||Dark Avengers #8|
|Created by||Matt Fraction
|In story information|
After the X-Men are chased out of their new base in San Francisco by Norman Osborn and the Dark Avengers, in the conclusion to the storyline "Utopia", Cyclops sets up the new headquarters and mutant sanctuary on the ruins of the original Asteroid M, which was raised from the bottom of the ocean.
Christening it "Utopia," this version is more of a haven than a base of operations, brought on not by a desire to make a place among mankind, but to simply get away from it. Although Utopia is sometimes referred to as a "mutant nation," it is as yet unclear if this is simply a figure of speech or if Utopia has literally seceded from the United States and is now a sovereign nation.
The island first appeared to be in trouble of only being a temporary home as the technology keeping it afloat was not stable and the island was starting to sink back into the ocean. However, a recently recruited Magneto was able to make a deal with Namor in which he and the Atlanteans would help construct a pillar underneath the island, connecting it to the ocean floor and keeping it afloat. This pillar would also serve as the new home to the Atlanteans, who had been scattered across the sea ever since Atlantis was destroyed.
The island underwent an dramatic transformation performed by the Phoenix Five, turning it into a virtual mutant paradise called "Pax Utopia", during Avengers vs. X-Men, until it was partially destroyed and fully abandoned after the events of the storyline were finished.
Other versions 
Ages of Apocalypse 
In the aftermach of the gathering of the Twelve, the Asteroid M was seen in a series of reality warps where Apocalypse attempted to use the X-Men and their powers.
Marvel Zombies 
In the Marvel Zombies universe, Asteroid M is in use when the zombie plague strikes that Earth. Magneto orders his acolytes to prepare it as the possible last, best hope for mankind. Despite Magneto's later death, it does eventually serve this purpose, acting as the basis for the last human colony. Its more notable residents include Fabian Cortez, Joanna Cargill, Black Panther, and Forge. Years later, the residents move back to Earth.
What If? 
In other media 
It should be noted, in all of its appearances in animation it is destroyed soon after it appears.
- In X-Men: Pryde of the X-Men, Asteroid M appears as Magneto's base of operations. After his escape from prison thanks to the Brotherhood of Evil Mutants (primarily the White Queen), Magneto steals Cerebro's "mutant power circuit" from Kitty Pryde, to whom it had been given by Professor X for its protection. Once he obtains the circuit he and his Brotherhood go to Asteroid M, and with a machine, use the circuit to amplify Magneto's power in order to change the course of the "Scorpio" comet, aiming it towards Earth. However, the X-Men stop his attempt to destroy the Earth when Nightcrawler reprograms the controls and makes the comet hit Asteroid M instead, resulting in its destruction.
- In X-Men: The Animated Series, Asteroid M appears in the two-part episode "Sanctuary." In the series, it has been built by Magneto with the goal of having it act as a sanctuary for all mutants, where they might live free from their human oppressors since he has become weary of battling for mutant supremacy. As such, he tells all of the world of his intentions for Asteroid M. He gathers many mutants from Earth (mainly from Genosha) and takes them to their new home in large transports. He has also previously gathered a large number of nuclear warheads to defend his new sanctuary. Soon the governments of the world feel threatened by Magneto's plan. They are intent on destroying Asteroid M, but through the interference of Professor X this is stopped. In his sanctuary, Magneto no longer cares about humanity. However, one of his followers, the Acolyte Fabian Cortez, desires nothing more than to destroy the humans. This eventually causes him to betray Magneto and jettison him towards Earth. Magneto survives however and is forced to destroy Asteroid M when he destroys hundreds of nuclear warheads Cortez has launched at the Earth in order to wipe out humanity.
- In X-Men: Evolution, Asteroid M appears in the two-part season 1 finale, "The Cauldron." In this version, Asteroid M isn't actually outside Earth's atmosphere, instead being placed a few miles above the Arctic Circle. In the episode, Magneto pits the X-Men and the Brotherhood of Evil Mutants against each other to see who is the "fittest" to join him at his sanctuary on Asteroid M. While some may have come voluntarily, others have been captured. On Asteroid M to those who survive his competition he gives the opportunity to "evolve" their powers, as he puts it, by being put in a machine powered by the Gem of Cyttorak. To show it is safe to use he lets Sabretooth go in as an example, failing to mention that it also alters the subjects mind to better suit his point of view. After the process is finished Sabretooth comes out more powerful and much more beast-like in appearance. Following him are Cyclops, Havok and later Mystique. Afterward fighting ensues that causes the destruction of the engines which keep Asteroid M at its high altitude, causing its impending crash on the surface below. To stop this, however, Cyclops and Havok use their newly enhanced abilities to destroy Asteroid M before it can do any harm, resulting not only in its obliteration but creating a wave which negates their new powers, reverting them back to their former states. Sabretooth also eventually reverts to his normal form, while Mystique and Magneto retain their enhanced powers.
