Synopsis:
After helping build canals on an alien world, Superman stops a giant meteor on a collision course with Earth. When he returns to the Daily Planet, he chest shield illuminates beneath his clothes, exposing his secret identity. Superman tries to get rid of the effect by bathing in the heart of the sun. He then returns to Earth, but his insignia fires deadly rays which kill his friends.

Superman learns that the rays came from a Doom Demon which he picked up during his demolition of the meteor. A space-hunter named Knarf has been hunting the demon, but is killed before he can tell Superman how to stop it. After Knarf's death, the demon tries to kill Superman too.

Superman then awakens on the alien world upon which he was building the canals. The aliens show him a chunk of Red Kryptonite that he was exposed to. Superman realizes that his encounter with the Doom Demon was only a dream. However, when he returns to Earth, he sees the same meteor on a collision course. Deducing that his dream was actually a prophecy of the future, Superman tracks down Knarf and learns that X-rays will neutralize the demon. He then uses his X-ray vision on it, preventing the rest of the prophecy from being fulfilled, and saving his friends.
