Comments:
Jimmy Olsen is inducted into the Legion of Super-Heroes as an honorary member.

The appearance of the Legion of Subsitute Heroes at Jimmy’s induction ceremony places this story chronologically after the existance of the Substitutes is revealed in the first story of Adventure Comics #315.

Synopsis:
Jimmy is abducted by a being calling himself the Collector and taken to an alien world. The Collector claims vibrations from Jimmy’s signal watch have penetrated his dimension and wrecked his cities. In an act of revenge he creates and unleashes five Olsen duplicates resembling Jimmy’s prior transformations: Turtle Boy, Porcupine Olsen, Fat Olsen, Wolf Boy, and Elastic Lad. The duplicate Olsen’s threaten Jimmy, but he convinces them to rebel against the Collector. The Collector defends himself against the attack and even scares off Superman.

Jimmy soon realizes that he is being hoaxed. The Olsen duplicates and the Collector are all disguised members of the Legion of Super-Heroes. He confronts them with his discovery, and they reveal themselves. The hoax was part of an initiation test designed for Jimmy. Having seen through the hoax, Jimmy is taken to the Legion’s time period and inducted as an honorary member.
