Writer Len Wein is joined by all-time great THOR artist Walter Simonson, and there's no question that what's in store will be legendary! Odin has disappeared, and Asgard needs its All-Father, so Thor ventures across the vastness of space to find him. But his quest will bring him into conflict with the Enchantress, the Executioner, the Destroyer and, of course, Loki! Then, Roy Thomas and John Buscema take up the hammer! Tapping deep into Thor's mythic roots, the duo crafts amazing adventures featuring the death of Balder, the Midgard Serpent and a new Norse Thor! Also featuring rare Thor and Hercules stories from MARVEL PREVIEW, a team-up with the Guardians of the Galaxy against Korvac, and the beginning of the epic Eternals saga! Collecting THOR (1966) #260-280 and ANNUAL #6-7, and MARVEL PREVIEW #10.
