New X-Men #155

New X-Men #155, published in 2004, serves as the concluding chapter of the acclaimed 'Planet X' story arc, which marked the finale of Grant Morrison’s transformative run on the title. The issue was written by Morrison and illustrated by Marc Silvestri, whose clean, muscular art style provided a distinct aesthetic shift from the previous run. The narrative directly addresses the catastrophic fallout of Xorn’s betrayal, focusing on the psychological and physical devastation left in the wake of the X-Men's struggle against Magneto.

This issue occupies a significant place in Marvel history as it serves as a bridge between the Morrison era and the subsequent relaunch of the X-Men franchise. The creative team aimed to ground the high-concept superhero action in the personal trauma of the students and faculty at Xavier’s School for Gifted Youngsters. It was received by readers and critics as a somber, character-driven conclusion that effectively closed the book on a period defined by subversion and radical reinvention of the mutant mythos.
