A rival network, and all that entails, are introduced by Maggin, Swan and Blaisdel in Action 458 (April 1976).
UBC has been causing a lot of problems for Morgan Edge. We discover that they have lured a number of anchors away from WGBS, including Lola Barnett. But the one thing WGBS has that UBC doesn’t is a super-hero. The head of the network, Tanner, orders the company scientist, Peter Silverstone, to create one. We see Silverstone fashion the gear and the costume, and decide on who the person inside must be.
But neither the reader nor Superman has any idea who is beneath the mask as this new hero appears, during a robbery by a vacuum truck. Superman mistakes the man for a criminal, and they wind up in a brief fight. This new hero can travel through the airwaves, and channel them through a miniature tv aerial he carries.
The story uses parallel structure well, as in the second robbery by the vacuum truck. Superman follows the radio control waves to the truck’s operator, while the new hero deals with the truck directly. Both believe they are responsible for the victory.
The new hero than manifests in Lola Barnett’s office at UBC, and she christens him Blackrock. About time. Was getting tedious avoiding using his name.
The issue concludes with some more pleasing parallel structure, as Edge and Tanner both freak out, wanting to know more about Blackrock.
The story concludes in the next issue.
Black Canary really loses it in the final back-up story that she shares with Green Arrow, by Maggin and Grell.
Luthor attempts to hypnotize Canary into killing Green Arrow, but it backfires, and she gets hypnotized into killing Luthor, and really tries. He barely escapes with his life.
When Green Arrow finally arrives, he is far more concerned with calming Dinah down, and bringing her back to herself. Luthor gets away, and a note informs us that he can be found next in the Joker’s book, where they work together. For part of it.
As for Green Arrow and Black Canary, they head back into Green Lantern’s series, as that gets revived.
And the Nutty Kid actually does sort of resemble Jerry Lewis in the final panel.
