Quentin Quire go to a mutant tattooist and have their arms marked with an Omega symbol over an X, then attack U-Men Central. Returning to school, the "Omega Gang" ambushes Professor X with a baseball bat and clamps his head in a thought-proof helmet. The next day, at the school's "Open Day" to parents and the media, Quire publicly proclaims it is "open season on humans" and starts a riot. Some of the students join Quire in protesting Xaviers' policies, but most of the damage is done by the Omegas themselves. They are finally subdued by Beast, Cyclops, Emma Frost and Xorn.
