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.

"[2] In the early books it 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.

During the Sentinel's attack, Cyclops orders Shadowcat and the students to go hide in the Danger Room for safety, finding the corpse of Wing.

Cyclops recovers, and Emma tells Danger to help the X-Men in Breakworld, and in exchange, it will be given Professor Xavier.

headquarters is destroyed during the Skrulls' Secret Invasion, Danger escapes and goes to Australia, taking on the form of an anthropologist from Melbourne University.

Danger tells Armor, that she constantly reboots herself, but can't wipe out Wing's image in her memory.

[volume & issue needed] Beast rebuilds the Westchester School at the behest of Wolverine at the aftermath of the Schism event.

Built on the ruins of the previous Xavier Institute, the school is rechristened the Jean Grey School for Higher Learning and is built with state of the art Shi'ar Technology, gifted by the current Emperor of the Shi'ar Empire Gladiator (Kallark) whose son Kid Gladiator is enrolled.

[25] Danger appears in the form of the Blackbird jet plane and is used as the main transport for the original time-displaced X-Men.

[26] During the Secret Empire storyline, Danger takes Jean Grey and Jimmy Hudson to a prison stronghold to rescue their captured teammates.

During the ensuing battle, she reveals her true form and projects holograms of the adult X-Men to keep the guards occupied.

[27] When Krakoa became a sovereign nation for mutants, Madison Jeffries tried to bring Danger with him but the island rejected the home he tried to build for her.

Madison was subsequently put into the Pit of Exile for breaking Krakoa's third law and Danger was forced to leave the island.

[28] Abandoned and alone, Danger joined and began working with the CIA's Dolores Ramirez and potentially the anti-mutant organization Orchis and is revealed to be behind the "X-Robots".

[29] It was later revealed by Third Eye's report that Danger is not a villain, but just a non-mutant being who has been abused and rejected by Krakoan society and abandoned by those meant to protect her.

As Danger gained self-awareness and adopted a more humanoid appearance, she has shown enhanced strength and durability, the abilities to create hard-light holographic projections that can affect entire areas, emit modulated energy waves for blasts, binding and protection, flight capability, mechanical regeneration & shapeshifting; with which to alternate her physical form as well as rebuild herself after her body is destroyed (at one point even rebuilding herself with butterfly-like wings which are soon destroyed by Beast), control and assimilate machinery and cybernetic components into herself via thought.

She is able to bring other machines into self-awareness and upload her consciousness into foreign digitized or mechanical systems to build, operate or otherwise commandeer new bodies.

Also, the student Prodigy, using the borrowed knowledge from several X-Men, built a "Danger Cave" underneath the X-Mansion that is a giant stone room with a large metal circle control center.

Danger is born from a literal revolution of consciousness; she becomes newly sentient and realizes that she is forced into a role that is not fulfilling and in which she cannot reach her potential...

Later, it was Dazzler who replaced the Danger Room and acted as a one-woman training facility for the fully fledged X-Men.
