Dark X-Men stories are something else. We’ve gotten some unforgettable moments from these books, one that have changed the way superhero stories work. These seven X-Men stories are the darkest ones, taking readers to the blackest portions of the human (and mutant) soul.
7) “Onslaught

“Onslaught” gets a bad rep, but it’s not all that bad. However, it is definitely a dark story. The X-Men learn that Xavier was the mysterious villain Onslaught, who beats the team and then launches an attack on New York City using a fleet of Sentinels. He captures Franklin Richards and X-Man to steal their powers, in an effort to destroy humanity, and eventually the human heroes of the world “sacrifice” themselves to defeat him. Every part of the story is dark, and it ends with the world hating mutants more than ever, putting the black cherry on the dark chocolate sundae.
6) “Final Execution”

“Final Execution” is the final story arc of the first volume of Uncanny X-Force and it saw Wolverine’s chickens come home to roost. He’s targeted by his son Daken, who brings together a new Brotherhood of Mutants to kill his father and his mutant hit squad. This whole story is about how bad a father Wolverine has been to Daken, and ends with the two of them trying to kill each other, with Logan drowning his son while they think of the kind of life they could have had if they hadn’t been who they are. It’s a tragic story about a life of hatred and death coming back to haunt everyone.
5) “The Dark Phoenix Saga”

“The Dark Phoenix Saga” changed the X-Men for years, with the death of Jean Grey redefining the team. This story was all about watching a member of the X-family fall to darkness because of a mental assault by an enemy, becoming a monster that ate billions of lives. The team’s battle against Dark Phoenix is heartbreaking, as the group does the best they can to beat without hurting her. Finally, her sacrificing herself for them after they lose their battle against the Shi’Ar Imperial Guard for her life is the pitch-black climax. It’s hit after hit of sadness, a book that wears its dark heart on its sleeve.
