Uncanny X-Men #1

Cyclops is the head of this group of X-Men housed on an island sanctuary off San Francisco called Utopia. They continue to battle negative perceptions of mutants and his idea is to form a team to battle evil and bring humanity around to their side. This team is grouped into subgroups, starting with what he has termed the Extinction Team, which includes Storm, Emma Frost, Magneto, Namor Colossus, Hope, Danger, and Magik.

In this issue, a mutant called Sinister, who takes the viewpoint that mutants are superior to humans and would prefer to exterminate them, takes control of the Celestial standing near San Francisco - this is a towering alien robot standing in the San Francisco area. This causes it to surge energy and the Extinction Team teleports there just in time for the head to launch off the shoulders - they immediately assume Sinister is behind it.

The giant head starts emitting rays that is able to disable Colossus and Emma Frost - Colossus changes into Juggernaut (???) and charges back in - ultimately Magneto takes control of the giant metal being (sans head). Sinister lands the head at the Palace of Fine Arts in downtown and with a release of energy turns everyone in the area into a faux Sinister. Fiendish! I'm sure it will accomplish something!
