Avengers Disassembled (Earth-1600)

Avengers Disassembled is a crossover event that primarily runs through the Avengers series.

Overview
When the Avengers come across a powerful force that may prove to be too great for them to handle, sacrifices must be made that might determine the future of Earth's Mightiest Heroes. The general concept is that the major heroes (the Avengers, Spider-Man, the Fantastic Four, the X-Men, and the Primitives) are assaulted, not just physically, but psychologically.
