Marvel Collectors' Item Classics #4

In "The Stonghold of Doctor Strange!" from Marvel Collectors' Item Classics #4 (1966), a criminal scientist uses his genius to hijack Iron Man’s armor, turning the hero into a weapon of mass destruction. With the world at his mercy, he demands to be crowned ruler—only to face resistance from the one person he never expected: his own daughter, torn between loyalty and conscience.

In his European castle, Baron Mordo schemes to steal the Ancient One’s secrets, sending his spirit to Tibet to poison the sorcerer’s food. From his New York sanctum, Stephen Strange senses the danger and confronts Mordo in a battle of wills across the spirit realm. The Ancient One warns Strange that Mordo remains a threat—alive and dangerous.

In "The Monster and the Machine!", Bruce Banner, still reeling from the strain of his monstrous form, takes a bold risk with his own gamma ray machinery—this time not to flee the Hulk, but to reclaim control. With the device now capable of shifting him between identities at will, Bruce finds himself caught between two selves, each with their own will, and a new kind of power—and peril—comes with the choice.
