Thor #404

Something ominous stirs in the depths as Thor #404 (June 1989) arrives with a cover — penciled by Ron Frenz and inked by Joe Sinnott — that sets an unmistakably foreboding tone. Thor and a sword-bearing warrior companion press cautiously through a rocky underground passage while a dark, cloaked figure lurks menacingly to the left, clawed hands reaching forward from the shadows. As a bonus, this issue also kicks off a brand-new Tales of Asgard super-epic, making it a satisfying double-feature for fans of Marvel's Asgardian corner of the universe.
