TheDanger Room is a fictional training facility^[1] appearing inAmerican comic books published byMarvel Comics. It first appeared inThe X-Men #1 (September 1963) and was created byStan Lee andJack Kirby. The facility is depicted as built for theX-Men as part of the various incarnations of theX-Mansion. Its primary purpose is to train the X-Men, initially using traps, projectile firing devices, flamethrowers, and mechanical dangers such as presses and collapsing walls. These were replaced byholographics, when the Danger Room was rebuilt usingShi'ar technology. It gained sentience inAstonishing X-Men asDanger.

An obstacle course in which the X-Men train appears inThe X-Men #1 (September 1963), but the Danger Room is never mentioned by name. The name "Danger Room" is first used inThe X-Men #2 (November 1963). According to X-Men writer/editor/co-creatorStan Lee, "the Danger Room wasJack Kirby's idea. I thought it was great because we could always open with an action sequence if we needed to."^[2]

In the early books, the Danger Room was filled with traps, projectile firing devices, flamethrowers, and mechanical dangers such as presses, collapsing walls and the like intended to challenge the trainee. Meanwhile, an observer is in the overhanging control booth^[3] managing the room's mechanisms to oversee the exercise while manually ensuring the subject's safety. Later the Danger Room was upgraded with machines and robots for the X-Men to fight against.^[4]

After befriending theShi'ar, the X-Men rebuilt the Danger Room with Shi'ar hard-lightholographic technology. These upgrades were largely added byBeast. The Danger Room is located in the X-Mansion; every destruction of the latter led to a rebuilding, and usually upgrading, of the Danger Room. The training facility has endured extensive damage over the years, usually from X-Men training or X-Men going rogue, asColossus did during theMuir Island Saga.Supervillains have dealt critical damage to it as well as taking over the facility, especiallyArcade. The security and safety protocols that ensure the safety of anyone using the Danger Room have frequently been disrupted, tampered with by villains, failed, or have been completely negated over time.

It is suggested in theX-Men Official Guide that the objects in the Danger Room are holograms surrounded by force fields, supposedly confirmed inAstonishing X-Men when a student managed to kill himself by jumping from a holographic cliff face. It is also revealed that the Danger Room can display holograms in only32-bit color.

With the Danger Room gone, the X-Men resorted to using the empty room to train with their students. The studentProdigy, using the borrowed knowledge from several X-Men, built a "Danger Cave" underneath the X-Mansion. The Danger Cave is similar to the Danger Room, but it uses holograms to train the students by re-enacting renowned battles the X-Men were involved in, like Inferno or Onslaught, even going so far as to dress the participants up in what the X-Men wore at that time.^{[citation needed]}

The Danger Room is well known and viewed as an iconic part of the X-Men mythos.^{[5][better source needed]}

The Danger Room equivalent in theAge of Apocalypse reality was the Killing Zone. The facility was located in Mount Wundagore^[6] and was apparently destroyed byNemesis. Later, it wasDazzler who replaced the Danger Room and acted as a one-woman training facility for the fully fledged X-Men.^{[volume & issue needed]}

TheUltimate Marvel version of the Danger Room has similar technology, including smaller holographic training rooms in the hiddensafehouses prepared for theX-Men. However, these are prone to malfunctions, such as a fight sequence producingHasidicrabbis instead ofninjas (though to no less of an effect towards the latter intent).^{[volume & issue needed]}

In the alternate universe ofWhat If? Astonishing X-Men, the Danger Room got a body of her own and betrayed the X-Men. She eventually marriedUltron and the two conquered Earth, theShi'ar Empire and the entire universe.^[7]
