"...And the Lights Went Out All Over the World!"
The power has gone out all around the city and the Fantastic Four individually save lives before making their way back to the Baxter Building to figure out what's going on.
The Avengers contact the Fantastic Four about the power outages, but no one has any answers so Reed and the FF head out to find the source of the power drain. They head north, over Canada on their way to the North Pole but their plane loses power and Ben crash lands the plane in the middle of a glacier.
Continuing on foot, the FF arrive at their destination, a strange base being built by aliens. The aliens' machine calls up a large crystal spire that spells doom for all of humanity.
