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.

X-Factor: The Original X-Men Omnibus Vol. 2 drives the reunited team into Inferno-era chaos, with Madelyne Pryor, Nathan, Mister Sinister and the X-Men reunion turning family drama into mutant crisis.

X-Factor: The Original X-Men Omnibus Vol. 1 reunites Cyclops, Jean, Beast, Iceman and Angel under a new public mission, while young mutants, Apocalypse and the Four Horsemen push the team into darker territory.

One of the absolute pinnacles of American superhero comics. Simonson introduces Beta Ray Bill (a horse alien who proves himself worthy of Mjölnir), brings back Surtur as a cosmic menace, transforms Thor into a frog, and elevated the character's mythology to unseen heights. If you're only going to read one Thor in your life, make it this one.
