Tales of Asgard #1

In "The Hordes of Harokin! [Warlock's Eye]," Thor faces a mysterious enemy whose true nature shocks even him—Harokin, a foe eerily similar in appearance, hints at a deeper mystery beneath the battle. With the help of the Warriors Three, Thor breaks the spell binding Asgard’s defenders, uncovering a threat that goes beyond brute force. Written by Stan Lee and brought to life with dynamic art by Jack Kirby, inks by Vince Colletta, colors by George Roussos, and letters by Sam Rosen, this 1984 Marvel classic features a striking cover by Walt Simonson.
