Maggin, Swan and Oskner conclude the Blackrock introduction storyline in Action 459 (May 1976).
Superman has come to terms with Blackrock operating in Metropolis, even though Morgan Edge continues to be furious, particularly at how Blackrock always gives his interviews to Lola Barnett at UBC. Clark points out some of the reasons for Lola changing networks.
Superman loses his patience with Blackrock during a robbery by teleporting thieves. The radio waves Blackrock uses short out the tech, preventing Superman from following them. Blackrock does not take well to being criticized, and the two start to fight.
Superman follows Blackrock back to UBC, but loses track of him. He goes to confront Tanner, certain that the man must know something about the hero, but is stunned to discover that Tanner himself is Blackrock. And Tanner does not even know it. Silverstone felt that only Tanner himself could live up to what he wanted Blackrock to be, and turned him into the hero.
But with Blackrock now out of control, Silverstone works with Superman to turn him off.
Tanner is left with no memory of being Blackrock. But Blackrock does return in a couple of years, in the pages of Superman.
The Private Life of Clark Kent begins as a rotating feature in Action. These stories, which deal with the non-Superman side of his life, began as a back-up in Superman. Here, this story begins a series that deals not only with Clark Kent, but with the personal lives of many of the supporting cast.
In this story, by Bridwell, Swan and Oskner, Morgan Edge demands that Clark find out what has happened to a prominent boxer. Steve Lombard has washed out on finding any information.
Clark pretty much stumbles across this one, winding up in a taxi that was meant to be part of a ransom pay-off. He follows the money, and frees the champ, meant to resemble Muhammed Ali, and winds up with a personal on-camera interview, while a pained Lombard looks on.
