Asteroid M is a large asteroid used as a headquarters for the Brotherhood of Mutant Terrorists.
At some point a small dragon made its home there, much to the annoyance of Magneto. At another point Magneto was captured by the military and released by the White Queen.
Once released Magneto set a plan into motion. He sent Blob and Pyro to the Deep Space Observatory to distract the X-Men while he and Juggernaut attack the Xavier Mansion to acquire the Mutant Power Circuit. It worked and the X-Men departed leaving Professor X and Kitty Pryde behind.
His plan was successful and the Brotherhood got the circuit and the coordinates.
Inside the asteroid Magneto told Toad to put the circuit into their computer, and then swatting away the small dragon. Toad did so then chased the small dragon away.
After recovering Xavier then used his powers to find and discover what Magneto was doing. On Asteroid M Magneto had successfully installed the Mutant Power Circuit and was diverting the Scorpio Comet towards Earth. It would have killed most of the human race so that mutants can rule.
Magneto watched on a monitor while Cyclops blasted his way through the airlock. Magneto sent the Brotherhood after them, after swatting away the dragon again.
The X-Men encountered Pyro so Dazzler decided to take him on. The X-Men went on without her until Toad surprised and attacked Wolverine. The other X-Men continued on only to run into the Juggernaut. Colossus took him on while Cyclops and Nightcrawler continued on. They encountered the White Queen who did battle with Cyclops. Nightcrawler went on by himself and teleported past the Blob.
He found Magneto who only taunted him. He tried to destroy Nightcrawler but Kitty phased up through the floor to stop him. Magneto was further distracted when the dragon bit his ankle. Magneto accidentally broke the circuit, which meant that nothing could change the comet's course. However, Xavier told Nightcrawler to complete the circuit while Kitty pushed Magneto back onto the platform. The resulting energies pushes away the Scorpio Comet, but sent it towards Asteroid M.
Unfortunately, Nightcrawler must have continued completing the circuit or else the comet would head back towards Earth. Magneto left with the Brotherhood back to Earth. Nightcrawler told Kitty to leave, as does Xavier since he had a plan. She grabbed the dragon and headed back towards the Blackbird.
Xavier kept the Blackbird on a viewscreen that Nightcrawler could see. Xavier told him that he must teleport aboard at the very last second. The plan worked and the comet hit the asteroid destroying both.
