The X-Men exist in the [[Marvel Universe]] along with other characters featured in Marvel Comics series and often interact with them. The X-Men/mutant corner of the Marvel Universe has been informally called "X-Universe".{{citation needed|date=April 2024}} For instance, [[Wolverine (character)|Wolverine]] was an antagonist to [[Hulk|the Hulk]] before joining the X-Men and has ties to other heroes such as [[Captain America]], [[Black Widow (Marvel Comics)|Black Widow]], [[Thing (comics)|the Thing]], [[Carol Danvers|Captain Marvel (Carol Danvers)]], [[Elektra (character)|Elektra]] and [[Spider-Man]]. [[Quicksilver (Marvel Comics)|Quicksilver]] and [[Scarlet Witch]] are former [[Brotherhood of Mutants]] members who joined the [[Avengers (comics)|Avengers]], as have other X-Men characters such as [[Beast (Marvel Comics)|Beast]]. [[Rogue (Marvel Comics)|Rogue]] got her powers via absorbing Carol Danvers (then called Ms. Marvel) who has also interacted with the X-Men. [[Kitty Pryde|Kitty Pryde/Shadowcat]] has been part of the [[Guardians of the Galaxy (2008 team)|Guardians of the Galaxy]] and dated [[Star-Lord]], she also served as a mentor to [[Franklin Richards (character)|Franklin Richards]] the mutant son of [[Mister Fantastic]] and [[Invisible Woman]] of the [[Fantastic Four]]. [[Storm (Marvel Comics)|Storm]] was once the Queen of [[Wakanda]] and the wife of [[Black Panther (character)|Black Panther]], as well as a temporary member of the Fantastic Four. [[Rachel Summers]] was the girlfriend of Franklin Richards. [[Iceman (Marvel Comics)|Iceman]] and [[Warren Worthington III|Angel]] have also joined [[Champions (1975 team)|the original Champions]] alongside Black Widow, [[Ghost Rider]] and [[Hercules (Marvel Comics)|Hercules]] as well as having frequent partnerships with [[Firestar (Marvel Comics)|Firestar]] and Spider-Man as "The Amazing Friends". [[Sabretooth (character)|Sabretooth]] was an [[Iron Fist (character)|Iron Fist]] villain before becoming Wolverine's archenemesis. After [[Avengers vs X-Men|a conflict over the Phoenix Force]], Captain America admitted to a remorseful but unrepentant Cyclops that the Avengers should have done more to help mutants, and not allowed the world to hate them. As a result, he formed a team called [[Uncanny Avengers]] (aka Avengers Unity Division) of both X-Men and Avengers members in hopes of unifying mutant and humankind. The global nature of the mutant concept means the scale of stories can be highly varied. The X-Men's enemies range from mutant thieves to galactic threats.

Historically, the X-Men have been based in the [[X-Mansion|Xavier Institute of Gifted Youngsters/X-Mansion]] located in [[North Salem, New York|Salem Center]], [[Westchester County, New York]], and are often portrayed as a family. The Xavier's School for Gifted Youngsters/X-Mansion is often depicted with three floors and two underground levels. To the outside world, it acted as a higher learning institute until the 2000s, when Xavier was publicly exposed as a mutant at which point it became a known mutant [[boarding school]]. Xavier funds a corporation aimed at reaching mutants worldwide, though it ceased to exist following the 2005 "Decimation" storyline. The X-Men benefit from advanced technology such as Xavier tracking down mutants with a device called [[Cerebro]] which amplifies his powers; the X-Men train within the [[Danger Room]], first depicted as a room full of weapons and booby traps, now as generating holographic simulations; and the X-Men travel in their [[Blackbird (comics)|Blackbird jet]].

===Fictional places===
The X-Men introduced several fictional locations which are regarded as important within the shared universe in which Marvel Comics characters exist:

* '''Asteroid M''', an asteroid made by Magneto, a mutant utopia and training facility off of the Earth's surface.
* '''Avalon''', Magneto's [[space station]] that served as the primary base for him and his [[Acolytes (comics)|Acolytes]] to create a mutants-only safe haven after Magneto drastically reverted to his villainous ways. Originally created by [[Cable (character)|Cable]].<ref>''X-Force'' #24</ref>
* '''[[Genosha]]''', an island near Madagascar and a longtime [[crime of apartheid|apartheid]] regime against mutants. The U.N. gave control to Magneto until the ''[[E Is for Extinction]]'' story saw Genosha destroyed via mass [[genocide]].
* '''[[Krakoa]]''', a living island which is currently home to the X-Men and other mutants. It is an official country.
* '''[[Otherplace|Limbo]]''', a hellish dimension heavily populated by demons. Whoever possesses the Soulsword bears control over and can draw power from Limbo. In ''[[Extraordinary X-Men]]'', the X-Men made a sanctuary in Limbo called ''X-Haven'' their home after Terrigen Mist made Earth uninhabitable for mutants.
