Collects Thor (1966) #437-450, Thor Annual (1966) #16-17. 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? Zarrko the Tomorrow Man may be more than even they can handle when he plucks a cadre of classic Thor villains out of the timestream to join him — including the scheming Loki! Meanwhile, Balder and Sif search for the real Odinson. When Dr. Donald Blake returns, could it be a clue? And why is Eric Masterson heading into Hell itself? Plus: Operation Galactic Storm takes Thor into space! Dargo meets the Guardians of the Galaxy! Thor battles Absorbing Man, Titania and…Spider-Man?! And the deadly debut of Bloodaxe!
