Marvel Girl along with several other X-Factor and X-Men stopped N'astirh from opening a portal to Limbo and releasing a swarm of Demons. However, unknown to them S'ym absorbed N'astirh's power and joined forces with Madelyne Pryor. The pair surprised the X-Men and there combined powers killed several X-Men. Wolverine saved Marvel Girl from the initial attack, but Madelyne telepathically grabbed them and killed Marvel Girl.[1]
