SUPERMAN'S PAL, JIMMY OLSEN 70 (July 1963)--1st story, "Jimmy Olsen's Boo-Boos" by Jerry Siegel and John Forte:
When Jimmy Olsen visits the Smallville chapter of the Jimmy Olsen Fan Club, he commits a series of boo-boos which enrage Superman--who takes back the signal watch and disavows his friendship with the cub reporter. Yet, in fact, this Jimmy Olsen Fan Club was really the Superman Junior Revenge Squad--children of the Revenge Squad. They set up Jimmy to fail.
However, Olsen figures out that the Fan Club were likely Revenge Squad aliens because they didn't drink the lemonade he prepared for them, which had ice cubes in it. And he knows the Revengers hate ice.
Reality Check: The title was no doubt inspired by the legions of fans who liked to point out boos-boos in their letters to the editor.
SUPERMAN 163 (August 1963)--1st story, "Wonder-Man, the New Hero of Metropolis" by Hamilton, Swan and Klein:
A new super-hero comes to town and the Metropolis Marvel feels like he's not needed. However, this Wonder-Man was once Superman's top robot, Ajax. When Ajax went into outer space to stop a meteor swarm, his robot body was damaged and salvaged by the Superman Revenge Squad, led by Attal, who has long had a vendetta against the Last Son of Krypton.
The Revengers transferred the Superman robot's consciousness into a biological android body, sending him to Earth to kill and replace his former master. However, Ajax understands that he is being used as a pawn and turns the tables on the S.R.S. As well, the so-called Wonder-Man knows that he has only a few days to live as his new body will soon expire.
Above his grave, Superman puts a headstone that reads:
Wonder-Man
Formerly Called Ajax
He Was
Born A Robot
...But
Died A Man
Reality Check: One of Superman's first competitors was a super-hero called Wonder Man--created by Will Eisner for Victor Fox, in WONDER COMICS 1 (May 1939). The attempt to trade off the success of the new sensation was rather blatant and the publishers of ACTION COMICS sued Victor Fox, putting an end to the first Wonder Man. The court decided that--
So far as the pictorial representations and verbal descriptions of Superman are not a mere delineation of a benevolent Hercules, but embody an arrangement of incidents and literary expressions original with the author, they are proper subjects of copyright and susceptible of infringement because of the monopoly afforded by the act . . . [but the] complainant is not entitled to a monopoly of the mere character of a "Superman" who is a blessing to mankind . . .
The ruling established a precedent for more court cases to follow. And there were more Wonder Men to come.
