Anti-mutant sentiment rises and the federal government launches its own covert anti-mutant program, Project Wideawake. Believing that the times have become too dangerous for the Brotherhood of Evil Mutants to continue, Mystique goes to Doctor Valerie Cooper, special assistant to the head of the National Security Council, and offers the Brotherhood's services to the government. In return for entering government service, Mystique and her team receive a presidential pardon for all criminal charges, to be revoked if any member of Freedom Force is found committing a crime. Cooper agrees to convey the offer to the President on the condition that the Brotherhood arrests their founder, Magneto. The Brotherhood, now reincarnated as Freedom Force, are defeated by Magneto and the X-Men. When Magneto learns that Freedom Force are official federal agents, he voluntarily surrenders to them.
