The Uncanny X-Men #335

Direct Edition

The Avengers and X-Man arrive at the decimated X-Mansion looking for survivors. The X-Men come out of the woods, and X-Man pulls an image of Onslaught from their collective minds. The teams discuss how Onslaught seems to be a combination of the psionic energy of both Professor X and Magneto. The teams split up as they try to figure out how to combat this new threat.
