The film introduces Wolverine and Rogue into the conflict between Professor Xavier's X-Men and the Brotherhood of Mutants, led by Magneto. Magneto intends to mutate world leaders at a United Nations summit with a machine he has built to bring about acceptance of mutantkind, but he was not aware that this forced mutation will result only in their deaths.
