New X-Men: Childhood's End

A brutal and necessary evolution for Marvel's mutant teens, New X-Men: Childhood's End (2006–2007) strips away the safety of Xavier's School as writers Chris Yost and Craig Kyle, alongside artist Mark Brooks, force the student body to confront a world that no longer coddles them. Following the devastating events of "Decimation," which left most mutants depowered, this five-issue series redefines what it means to be a young X-Man in a hostile new era, where survival and responsibility are the only lessons that matter. It's a pivotal turning point for the franchise, marking the transition from youthful adventures to a grittier, more desperate tone that would define the team for years to come.
