Warning: The following contains spoilers for Captain Marvel #23 by Kelly Thompson, Lee Garbett, Belén Ortega, Antonio Fabela, and VC's Clayton Cowles, available now.
Since the mutant nation of Krakoa formed, the X-Men's outlook on the world and their place in it has seemed to change significantly. With a few notable exceptions, the mutant heroes have mostly abandoned their usual ideology of fighting for a world that hates and fears them, instead of seeming to focus solely on protecting their own kind from that world.
But in Captain Marvel #23 Carol Danvers learned the history of a possible future timeline and while it was mostly tragic it did feature the X-Men fighting side by side with non-mutant heroes, suggesting that the mutants may still learn to care for the rest of the world again.
The formation of Krakoa, with its united population of mutants, many of which are former enemies, represented a radical shift in the X-Men's ideology. Charles Xavier made this plain in House of X #6 by Jonathan Hickman, Pepe Larraz, Marte Garcia, David Curiel, VC's Clayton Cowles, and Tom Muller. Xavier sent a telepathic message to the humans of the world informing them that mutant scientists had created drugs that could cure some of the world's most common, destructive illnesses including Alzheimer's and "many cancers." He explained that while in the past the mutants would have freely given these drugs to those humans who needed them, as an effort to work towards Xavier's dream of peace and harmony between man and mutant, the humans have proven to him over the years, through all their cruel attacks against mutants, that "That dream was a lie." He declared that only nations that recognized Krakoan sovereignty and that all mutants are entitled to Krakoan citizenship would receive the drugs. This kind of pragmatic stance would become the usual one for the Krakoans, who now always prioritize mutant needs above those of non-mutants.
This ideology has led the mutants to drift away from their connections to humanity and led characters to question the morality of Krakoa. Some of the mutants themselves, including Cyclops and Nightcrawler, among others, have questioned how Krakoa is run but even they have mostly kept to its isolationist ways. Ironically enough Wolverine, who maintains connections to many non-mutant superheroes, is one of the only mutants who has not let the other aspects of his identity become subsumed by his status as a mutant and Krakoan. He and a handful of others have questioned where the Krakoan ideology will lead mutants in the future.
Despite being a bleak dystopia, the future Captain Marvel has found herself in during her series' current story arc offers a glimpse of hope that the mutants will become less isolated going forward. In Captain Marvel #23 Carol leads a team of future heroes to a confrontation with the mysterious Ove. Among them are Emma Frost, Rogue and Gambit's daughter, Forge and Kwannon's daughter, and a being called Fantomex 5, working side by side with the children of non-mutant heroes like Dani Cage and Thor's daughter. Carol asks the group to explain to her how the world turned out like it did and they tell her of two wars with an enemy they still know little about but suspect may be alien. They describe the X-Men as working with the Earth's other heroes to fight for the planet and flashback images show Cyclops, Storm, Rogue, Armor, and others involved in the battles. It is implied that most of the characters not appearing in the future scenes died in the conflicts. Magneto sacrificed himself to build the underground sanctuary where the resistance lives.
Many post-"Dawn of X" stories imply that the corruption of Krakoa is leading mutantkind to some kind of dire reckoning, whether that's the ongoing conflict with Arakko or something worse. But this issue of Captain Marvel indicates that it may still be possible for the X-Men to reunite with humanity. One just hopes that it won't take such a drastic threat to get them to do so.
