Professor X hasn't been himself lately - moody, inscrutable - but the psionic armor and army of Sentinels are the real tip-offs! It'll take every super hero New York has to face the Onslaught - including not only the X-Men, X-Factor and X-Force, but also forgotten stars of the nineties like Phil Urich, the Green Goblin; Nate Grey, the X-Man; and Ben Reilly, a.k.a. Spider-Man! Also guest-starring the Punisher, S.H.I.E.L.D. and others!
