To spare a life, Thor makes the ultimate sacrifice. With the fate of his friend Eric Masterson in the balance, Thor steps in and finds himself once again bonded to a mortal form. But which deadly foe will bring about such dire straits. Could it be Quicksand. The maniacal Mongoose. A new Executioner or as an untethered Asgard drifts into the Negative Zone, Annihilus. As a new era begins for Thor, another legendary hero returns: Zounds, it's Hercules. It will take the combined might of these godly friends, plus She-Hulk, to face not one but two Dooms. In another heavyweight bout, Thor takes on the Juggernaut with the New Warriors lending a hand. Collecting THOR (1966) #401-418 and ANNUAL #14.
