Ultimate Comics: The Ultimates #2

THE REPUBLIC IS BURNING PART 2 The Ultimates are spread too thin.  With disasters igniting across the globe and Captain America quitting after the death of Spider-Man, Fury's superhuman taskforce is at its limit. Though nearly killed by a nuclear bomb in Uruguay, Iron Man manages to join Thor in Europe to help stop the Children of Tomorrow, a highly-evolved race of humans bent on reshaping the world. The Children have rapidly expanded their home-base, an advanced civilization known as The City, into neighboring European countries, threatening humans and gods alike. Pushed to the edge, Thor gathers the combined might of his fellow Asgardian gods to take a stand. However, the Children of Tomorrow prove to be too powerful, destroying Asgard, killing the gods - and cutting Thor off from the very source of his power.
