Ultimate X-Men #001

the long version

The place is a world very much like ours. The time is now. The phenomenon is genetic mutation. It is a time of change. Humanity now faces mutants, a mysterious sub-species that is gifted with strange and frightening powers. Hidden among the population, they are feared and hated by their human cousins. As rumors and urban myths about their existence spread across the world, the U.S. Government creates its own initiative to deal with this threat: the Sentinel Project.
