X-Corp works with local governments, such as when they took in the superstrong twelve-year-old orphan Molly Hayes on behalf of the Social Services of Los Angeles.
It should not be confused with the X-Corps, a short-lived paramilitary team led by Banshee, which merged with the X-Corporation after its dissolution, most of its members transferring to the Paris branch.
In the wake of the Decimation of mutantkind, wherein 90-95% of the mutant population was rendered genetically and physically human and thus powerless, several bombings occurred at X-Corporation locales.
For the safety of those operating the facilities, and to regroup all empowered members, Cyclops ordered the evacuation of all X-Corp offices and the organization appears to be dead.
In the Marvel Trading Card Game, X-Corp is the evil scientific corporation that is controlled by the Hobgoblin, from the Spider-Man series.
