Superman Supacomic #64

In "The Nightmare Ordeal of Superman," the Man of Steel finds himself stripped of his powers on a planet bathed in a red sun, reduced to mortal weakness. After being overpowered by a tribe of primitive cavemen—one of whom steals his iconic suit—Superman must endure a brutal test of will and endurance. When Jimmy Olsen and Lois Lane arrive in a spaceship to rescue him, they discover a far more vulnerable hero than they’ve ever known.

In "The Raid from the Phantom Zone!", Superboy is sent a mysterious giant box of Red Kryptonite—when he opens it, the strange substance plunges him into a vivid dream where he unwittingly frees the Phantom Zone prisoners. The dream spirals into a tense, surreal sequence as the imprisoned aliens begin their long-awaited return, testing Superboy’s resolve in a vision that blurs reality and nightmare.
