If death be his destiny. When the High Evolutionary plans a new race of immortals in the Black Galaxy, Hercules and the Celestials play a part in a spacefaring saga with major implications for Thor and his new mortal host, Eric Masterson. Thor will experience flame, frost and fury courtesy of Surtur and Ymir but will a new god take charge of Asgard. On Earth, Code Blue serves and protects New York from superhuman dangers like the Wrecking Crew but things get out of hand when Thor and Excalibur take on the unstoppable Juggernaut. Collecting THOR (1966) #419-436 and ANNUAL #15.
