When you create a treatment that seemingly every mutant can be converted into a normal human being, there is anger among the mutant community. While some mutants, such as the idea of a cure, including Rogue find many mutants that there should be no healing. Magneto, who still believes that there is a war, recruits to kill a large group of mutants Warren Worthington II and its healing. It may seem easy for the X-Men to stop, but it has one big advantage Magneto, Wolverine does not. Jean Grey is back, and with Magneto. Phoenix was awakened in her, which has the ability to destroy everything in their path, even if that “something” is an X-Men.
