Time Heist (Earth-1600)

The Time Heist was a planned mission by the remaining Avengers, X-Men, Fantastic Four, and individual heroes to retrieve the six Infinity Stones from key events to undo Thanos' Decimation. The mission began after Ant-Man (Scott Lang) traveled to the Avengers Facility and explained the Quantum Realm, believing it could be navigated for time-travel.
