History
The X-Mansion is the inherited property of Charles Xavier (Professor X) and has been in the Xavier family for ten generations including two known mutants in the lineage, both becoming detached from the family. Little else is known about them or their mutations.
As Xavier's School for Gifted Youngsters, the X-Mansion was the training site of the first two generations of teenage X-Men:
In X-Men (vol. 2) #38 (November 1994), the X-Mansion was renamed from Xavier's School for Gifted Youngsters to the Xavier Institute for Higher Learning, as most of the X-Men were adults rather than teenagers by this time. Xavier's School for Gifted Youngsters was relocated to the Massachusetts Academy in Western Massachusetts (a Marvel created town or region called Snow Valley somewhere in The Berkshires), which served as the training site of the third generation of teenage X-Men beginning in Generation X #1 (November 1994).
The Massachusetts Academy closes permanently in Generation X #75 (June 2001). Shortly thereafter, the school for young mutants is reopened at the X-Mansion, but the name remains "The Xavier Institute for Higher Learning" despite the younger student body. The fourth generation of mutant teenagers, featured in Grant Morrison's New X-Men (2001–2004) and in New Mutants (2003–2004; relaunched as New X-Men: Academy X, July 2004–February 2008), study at the mansion until it is destroyed during the 2007–2008 story "Messiah Complex" and the X-Men subsequently disband and close the institute.
Though protected by high-tech defenses, the X-Mansion has often been breached by the supervillains and evil mutants faced by the X-Men. Indeed, the X-Mansion has been destroyed and rebuilt several times. It was demolished in a battle with the Sidri in The Uncanny X-Men #154 (February 1982) and atomized by Mister Sinister in The Uncanny X-Men #243 (April 1989). It was rebuilt by a future Franklin Richards in moments, but reverted to its destroyed state after the time-traveler became confused.[7]
Certain portions of the mansion, such as extensive sub-basements, survived both demolitions. When Onslaught revealed himself and fought the X-Men (X-Men #54 (June 1996) and Onslaught: X-Men), the mansion took heavy damage, though was quickly repaired in-between issues after the "Onslaught" storyline. In "Operation: Zero Tolerance", Bastion forced Jubilee to reveal the mansion's defenses. He stripped down the mansion and had everything inside it removed. After defeating Bastion, the X-Men moved back into the mansion, as detailed in X-Men #70 (November 1997). The X-Mansion survived an assault by the Shi'ar in New X-Men #122–126 (March–July 2002) as well as a riot by students led by Quentin Quire in New X-Men #134–138 (Jan.–May 2003). In the "Planet X" storyline of New X-Men #146–150, the X-Mansion was destroyed; the rebuilding process could be seen in New X-Men #155–156 (June 2004). In the wake of M-Day, the mansion was infiltrated by followers of William Stryker in an attempt to wipe out the students, resulting in some structural damage and several casualties. Then the mansion was severely damaged when the Danger Room became sentient and summoned local machinery to attack the structure. The mansion was also damaged when the Marauders attacked the mansion. A fight between the Hulk and several mutants heavily damaged the mansion. In the "Messiah Complex" storyline, the mansion is destroyed by Sentinels.
Unlike past times, the mansion was not rebuilt for a considerable length of time.[8] Rather, the X-Men and their students relocated to a new base of operations in San Francisco. Under the name Graymalkin Industries, the new X-base is not run as a school, but rather as a sort of community center for mutants who wish to develop their powers.
- The X-Men: 1st Class – Cyclops, Iceman, Angel, Beast, Jean Grey (Marvel Girl) and then later Havok, Polaris, Mimic, and Changeling join the team as well.
- The original New Mutants – Cannonball, Wolfsbane, Mirage, Karma, Sunspot, Cypher, Magma, Magik, and Warlock along with Shadowcat, a contemporary member of the original New Mutants who was their classmate but was a member of the adult X-Men team instead.
- Generation X – Skin, Synch, M, Husk, Jubilee, Chamber, Blink, Mondo, Gaia, and Penance
Faculty (pre-Messiah Complex)
- Shadowcat teaches computer science classes and, in addition to being a member of the senior staff, acts as a student advisor and liaison for the senior staff.
- Karma teaches French and is in charge of students who are too young to join the training squads. She also oversees the library.
- Nightcrawler teaches music, art, life sciences, and drama.
- Beast teaches science and mathematics and is part of the senior staff, presumably overseeing the curriculum.
- Emma Frost, besides being the headmistress of the Xavier Institute, also teaches English, business, and ethics, much to the horror of Kitty Pryde. She also presides over the new team of X-Men, teaching them to work as a team, with some assistance from the senior staff, such as Colossus.
- Wolverine teaches close quarters combat.
- Cyclops, besides being the headmaster of the Xavier Institute, also teaches the elective leadership and tactics.
- Northstar, before his death (and later resurrection), taught business and consumer law classes, as well as a flying class for those students with flight powers. He also mentored the Alpha Squadron training squad.
