Collider's David Caballero argues that Immortal X-Men is the standout X-Men comic of the past decade, praising it for trading traditional superhero action for a political, Game of Thrones-style drama built around power, ambition and betrayal. The 18-issue series is set during Marvel's "Krakoan Age," when mutants formed the sovereign island-nation of Krakoa, and it focuses on the internal machinations of the Quiet Council, the body governing the mutant homeland. This shift towards character-driven political intrigue is credited with producing the most layered and compelling mutant storyline in years, reinforcing the X-Men's reputation as one of Marvel's most versatile franchises.

The article explains the series' backdrop, rooted in the 2019 House of X and Powers of X miniseries, in which Charles Xavier and Magneto establish Krakoa as a sentient, hive-minded island offering amnesty to all mutants. The Quiet Council is made up of twelve members split across four factions named after the seasons, each with distinct roles ranging from diplomacy to overseeing the island's most dangerous figures, though the line-up shifts as characters like Magneto depart over the course of the run. The piece is published as Marvel builds anticipation for the X-Men's MCU debut, noting recent castings such as Sadie Sink as Jean Grey, Samara Weaving as Emma Frost and Kit Connor as Scott Summers.
