X-Men: Children of the Atom, and the home stage of Sentinel. This stage takes place in a Sentinel production facility. This stage is located northeast of Madagascar.
- In the comics, Genosha is a country that uses its mutant population as slave labor. Eventually, the government was overthrown and the country was taken over by Magneto, who sought to make it a haven for mutantkind before being destroyed by a group of Sentinels.
- Though the Sentinels are not usually associated with Genosha in the comics, a Sentinel facility in the country was visited in an episode of the X-Men animated series, which may be the inspiration for the stage.
