Professor X recruits a new team of X-Men, to rescue the original X-Men, who had disappeared on a mission to the island of Krakoa, with only their leader Cyclops escaping. The new team consists of Sunfire and Banshee, Wolverine, and the newly created Storm, Nightcrawler, Colossus, and Thunderbird. These members are gathered from all over the world.
The team soon learns that Krakoa is not just an island, but a giant mutant as well. Despite a number of personality clashes among the individual members, the new team succeeds in rescuing the old X-Men as well as destroying the island by shooting it into outer space with Polaris' power.
