The story opens in medias res, with Professor X recruiting a new team of X-Men, to rescue the original X-Men (Marvel Girl, Iceman and Angel [but not Beast, who had left the team], plus X-Men recruits Havok and Polaris), who had disappeared on a mission to the island of Krakoa, with only their leader Cyclops escaping. The new team consists ofSunfire and Banshee, who had been introduced in earlier X-Men comics; Wolverine, who had made his first appearance in The Incredible Hulk #181 (Oct. 1974); and the newly created Storm, Nightcrawler, Colossus, and Thunderbird. These members are gathered from all over the world, and so Professor X uses his telepathic powers to teach them all English so that they can communicate with each other.
