The X-Men detect the presence of a very powerful being, but are unable to see who or what it is. In the city a man is walking through town when he comes across a busy intersection. The man decides to just levitate and walk above the traffic until he realizes that he is causing a commotion. The man phases through the wall of a building that he had some strange attraction to. Inside he is greeted by Magneto and the Brotherhood of Evil Mutants. Meanwhile the X-Men have begun a search for the powerful being believing that he is a mutant.
Magneto asks the Stranger to join the Brotherhood. In an attempt to impress the Stranger, Magneto ties him up with cables and Mastermind projects illusions of being under the ocean. The Stranger is unimpressed and uses his powers to free himself and turn Mastermind into a statue. The X-Men see the scene from outside and rush into the building where they face off against the Brotherhood. The Stranger decides to depart and opens up a vortex to depart. Magneto decides to follow him in an attempt to recruit the Stranger and the loyal Toad follows as well. The Scarlet Witch and Quicksilver are the only villains left, but they both inform the X-Men that they are quitting the Brotherhood because they feel that they paid off their debt to Magneto and want to return to Europe.
The Stranger's vortex leads the three villains into a wooded area where Magneto demands to know what kind of mutant the Stranger is. The Stranger informs him that he is an alien from a distant planet. Believing that he is too powerful, Magneto tries to stop the Stranger, but is imprisoned instead. The X-Men are able to find the wooded area and soon find Magneto and Toad encased in their prisons. The Stranger informs them that he will be taking them back to his home planet to study their mutations and takes off. The X-Men leave the area as well when they hear police sirens. Back at the mansion, the X-Men are startled by Cerebro which has detected another very powerful presence nearby.
