The Mighty World of Marvel #123

When a secret plan to contain the Hulk goes awry, the world’s greatest heroes—Mister Fantastic, Iron Man, Captain America, Thor, Black Panther, and others—find themselves drawn into a cosmic conspiracy. A mysterious alien force, wielding ancient powers and a touch of voo-doo, has taken the Hulk, and now the fate of Earth may rest on whether the heroes can track him down before the dark gods awaken.

In a bold move to outwit Cobra and Mister Hyde, Daredevil dons the guise of Thor—only to find the real Thor, in the form of Donald Blake, far from amused. When the thunder god tests Matt Murdock’s worthiness, the trial leads to a clash with the villains, culminating in Daredevil losing his enhanced senses to one of Hyde’s experiments, leaving him truly blind.
