Marvel Comics

X-Men: Mutant Massacre Omnibus is one of the X-line’s most brutal turning points, sending the team into the Morlock tunnels and leaving wounds that echo through years of stories. Chris Claremont, Louise Simonson, Marc Silvestri, Rick Leonardi and Walter Simonson make the event feel like trauma rather than spectacle. This is not just a famous X-Men crossover; it is a wound in the line. The Morlock material gives the story a human cost, and the aftermath keeps echoing through characters who cannot simply move on.
