The Mighty Thor #6

In "Challenged by the Human Cobra!", Don Blake’s visit to India takes a dark turn when he discovers the murder of an old teacher at the hands of a snake-powered villain. As Thor, he battles the serpent-like foe in New York, but the real test comes when Jane Foster, once Doctor Andrews’ employee, sees the limits of her new boss’s courage and returns to working with Blake.

In "The Mysterious Mister Hyde!", Calvin Zabo, scorned after being denied a job by Doctor Blake, transforms into the rampaging Mister Hyde and strikes out in vengeance. When Blake survives—thanks to Thor’s intervention—Hyde’s rage turns to a new target, and the god of thunder finds himself framed for a bank robbery, sparking a manhunt that tests Jane Foster’s worthiness and Thor’s resolve.

In "Surtur the Fire Demon!", the ancient fire demon Surtur rises to challenge Asgard, rallying the Trolls to his cause. When Odin thwarts their assault, Surtur turns his fury toward Earth, only to be defeated once more—this time banished deep beneath the planet’s surface. Their cataclysmic clash reshapes the world, forging the moon and setting Earth spinning on its axis.

In "The Master Plan of Mr. Hyde!", the sinister Mr. Hyde takes Don Blake and Jane Foster hostage, using Jane as leverage to steal a submarine. As Thor races to stop him, Jane’s desperate attempt to protect Don leads her to halt Thor’s pursuit—only to later realize she’s been manipulated. The truth behind the bank robbery unfolds, and Jane’s actions ultimately challenge her worthiness in Odin’s eyes.
