Following the events of the M-Day, several mutants lost their powers, including several students from the Xavier Institute and the main squads (New Mutants and Hellions (squad)). The remaining members (who remained with his powers) were recruited for a trainee team of X-Men. The team faced many enemies, like: reverend William Stryker; Nimrod; Predator X; Belasco, among others.
Recently, after the confrontations with Lady Deathstrike (and her Reavers); Purifiers; Predator X and Marauders, Hellion was severely wounded; X-23 joined X-Force; the members dispersed, and the New X-Men team disbanded.
