Synopsis for "Day of the Atom (Part 3)"
Havok manages to keep Xorn from opening a black hole with his powers. The Eight Immortals return and inform them of another helmet for the Xorn. They take all the X-Men save Havok, Iceman, and Juggernaut, who stay with Xorn. Soon, however, the Collective Man appears and fights Iceman and Juggernaut. The other X-Men are actually tricked and they find more Collective Men to fight before they can get the helmet.
