Myth-making writer Al Ewing continues his unpredictable saga! In Asgard, Thor weighed his obligations as All-Father and as Gaea's child - and what he owed to both sides of his nature. Meanwhile, on Earth, a risen evil sought new gods to challenge the old - and found them in Thor's earliest foes. That puts the God of Thunder on a collision course with the Radioactive Man, the Grey Gargoyle, the Cobra and Mister Hyde! All have plenty reason to hate him - and working together, they have the power to end an All-Father's reign! Plus: What shocking game is the Enchantress playing? And a cavalcade of artists joins the fun to tell Tales of Asgard! Collecting IMMORTAL THOR #16-20.
