Plot
While the X-Men celebrate their one year anniversary of becoming X-Men, Magneto's Brotherhood of Evil Mutants captures a Naval convoy freighter, which they use, along with Mastermind's illusions, to conquer the South American Nation of Santo Marco. The X-Men intervene, taking on the Brotherhood. The X-Men manage to force Magneto and the Brotherhood to abandon the country, but not before Quicksilver disables a nuclear bomb Magneto left behind and an additional booby-trap seemingly robs Professor X of his power, making the X-Men's victory bittersweet.
