The Aquaman story in Adventure 447 (Oct 76) feels a bit like a filler issue, before the full length story in the following issue. Paul Levitz, Marty Pasko and Jim Aparo craft a decent enough tale, but it really does little except lead up to the coming resolution.
After bidding farewell to Aqualad and Aquagirl, Aquaman pursues the gun-smuggling operation to a Civil War mementos factory on land, and falls into the hands of the Fisherman.
The Fisherman is working as hired muscle for Black Manta, and his fight with Aquaman takes up most of the issue. Only at the end do we see Manta and Karshon plotting together. There is also a brief scene with Mera and Aquababy, presumably just to remind us they are part of the story as well.
The Karshon plotline concludes next issue.
The third and final chapter of the Creeper story is a bit better than the previous two. Not that Marty Pasko has remembered to make Jack Ryder abrasive, but Ric Estrada and Joe Staton’ s art is satisfactory.
It turns out the Maddox’s robot is acting on his unconscious whims, but no less deadly for that. The Creeper manages to get him to face his creation, in order to stop it.
That doesn’t work exactly as planned, as Maddox dies destroying the robot, but the physiotherapist gains the ability to walk again, even though the telepathy thing is a bit of a stretch.
Jack Ryder has a cameo in Teen Titans, and the Creeper next appears in Secret Society of Super-Villains. His next run at a series is in World’s Finest Comics, with his creator, Steve Ditko, returning to helm the character.
