John Romita Jr.

Avengers vs. X-Men Omnibus — the Phoenix Force returns to Earth and splits the Marvel universe. Captain America vs. Cyclops, the Phoenix Five transform the world, Hope Summers as the chosen one. The event that changed everything. Avengers vs. X-Men #0-12 plus AVX: VS #1-6 and AvX Consequences #1-5 collected in the complete omnibus. The Phoenix Force returns to Earth targeting Hope Summers — Captain America demands she be handed over, Cyclops refuses. Twelve issues of Marvel's biggest superhero war: the Avengers fighting the Phoenix Five (Cyclops, Emma, Namor, Colossus, Magik with Phoenix power). Ends with Cyclops in prison and the mutant population beginning to rise again. The event that launched the All-New Marvel NOW era.

X-Men: Mutant Massacre Prelude Omnibus gathers the material that makes the later disaster land harder, showing the X-Men world before the tunnels become a wound. Chris Claremont, Barry Windsor-Smith and John Romita Jr. give the prelude its tension: relationships, threats and unease gathering before the line changes shape. It is useful because it lets the reader feel the world before impact. The tension is quieter than the massacre itself, but that quiet makes the later violence harder to dismiss as just another crossover.

Chris Claremont assembles a dream team of artists — John Romita Jr., Arthur Adams, Barry Windsor-Smith and Dave Cockrum — for this massive fifth omnibus collecting issues #194-209 plus the complete Longshot and Nightcrawler limited series. The Juggernaut makes an earthshaking return, the second Lifedeath story explores Storm's journey without powers, and the Asgardian Wars crossover sends the X-Men and New Mutants into Norse mythology. Nathan Summers is born and Rachel Summers grapples with the Phoenix Force, while Barry Windsor-Smith crafts the defining Wolverine solo tale Wounded Wolf. This volume also introduces Longshot, the lucky six-fingered warrior from the Mojoverse, in Arthur Adams' career-making limited series that became an instant classic.

Uncanny X-Men Omnibus Vol. 4 catches the Claremont era in a rich, unstable stretch, with Arthur Adams, John Romita Jr. and the art team giving the mutant world sharp visual range. The team’s relationships, fears and transformations keep expanding, making the volume feel like long-form character drama disguised as superhero adventure. For collectors, the attraction is the density of the Claremont period: every relationship has history, every transformation leaves residue, and the superhero plots keep feeding a larger emotional machine.
