Once again the final story in the book gets the cover of Superman 117 (Nov. 57).
It’s been a long time since we have seen Superman’s mountain Citadel, and the Fortress of Solitude was still to come when Otto Binder, Boring and Kaye crafted this tale.
Luthor plays a small role in the story, having Superman use his powers to destroy a device, which was really a decoy. Unwittingly, Superman opened a passage to another dimension, allowing creatures to come through.
Superman constructs a fort outside of the city, stocking it with trophies and exotic creatures – a clear forerunner of the Fortress.
But in this case, it’s all a big trap. Lois Lane and Jimmy Olsen come to investigate, and Superman has to keep them out of the way as the other-dimensional beings fall for the deadly treasures in the fort, eventually fleeing Earth.
Superman winds up with cold vision in this Plastino story, after using his heat vision to destroy an odd alien object.
For no clear reason, this causes all of his other vision powers to create extreme cold at the same time.
The resolution does not make a lot of sense either, at the time it was written. Superman basically resets his powers by flying into the sun. He will do that again, in years to come, but only after the source of his powers is given as sunlight. At this time, gravity is still the only given explanation, so flying into the sun really should have no effect.
