It's a Marvel team-up for the ages in this 4-issue weekly limited series event! When a highly coveted piece of alien Shi'Ar technology en route from the X-Men's headquarters to Avengers Mansion gets intercepted by a rogue group of ex-S.H.I.E.L.D. super agents, both teams send their best chance to get it back into the field! Can these two VERY different heroes work together for a common cause?
