Thor Corps unite! Eric Masterson is still settling into his role as the replacement Thor - and Hercules' "training" isn't much help. Will Eric be able to keep up when he joins forces with Beta Ray Bill and Dargo Ktor, the 26th-century Thunder God?

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?
