Fan Casting X-Men: Modern Warfare 3

Worthington Labs announces it has developed an inoculation to suppress the X-gene that gives mutants their abilities and offer the "cure" to any mutant who wants it. The cure is created from the genome of a young mutant named Jimmy, who lives at the Worthington facility on Alcatraz Island. While some mutants are interested in the cure, including the X-Men's Rogue, many others are horrified by the announcement. Magneto re-establishes his Brotherhood of Mutants with those who oppose the cure, warning his followers that the cure will be forcefully used to exterminate the mutant race.
