Synopsis for "From the Void It Came..."
A brooding Namor gets into a confrontation with a couple of surface dwellers. They attack Namor which leads to a fight. Then he's attacked by an alien creature and also retaliates against it. The defeated creature escapes and Namor is left to wonder what its purpose was.
- The Sub-Mariner next appears in Giant-Size Super-Villain Team-Up #1.
- This story serves as unofficial conclusion (and crossover) by writer Steve Skeates of Aquaman #56 over at DC Comics. The title character's hand appears pushing the button that destroys the satellite boarded by the Slime-Thing in the beginning of the story, like he does in the end of the aforementioned comic. This issue's narrator makes the odd remark that the identity of that person is not of the reader's concern.
