Another split cover on Adventure 477 (Nov 80), and the final one to really feature Starman and Plastic Man.
Aquaman leaves New Venice by mutual agreement as this story, by J.M. DeMatteis and Dick Giordano, begins. The mayor is furious with him for abandoning so many of this plot lines from World’s Finest Comics.
But another long-abandoned character shows up, Cal Durham, formerly one of Black Manta’s men, now forced to live underwater. His young sister goes to Aquaman for help. Cal had last appeared in Aquaman’s brief 70’s revival, along with Manta.
And it’s Black Manta that is the trouble once again, capturing the two after Cal stumbles across Manta’s new base, from which he plans to attack and conquer Atlantis.
On the last page, Mera re-appears. She had not be taken, so much as phased away, and now back, still all feverish and comatose.
Starman goes in search of Mn’torr in this chapter, by Paul Levitz, Steve Ditko and Romeo Tanghal.
He heads to a trippy temple Mn’torr was connected with, which speaks to him and allows him to essentially teleport to Mn’torr’s homeworld.
We discover that he broke sacred vows about the balance of the universe when he rescued Prince Gavyn, and that he was not defeated by Oswin, but by his own people, who gave Oswin the staff to balance the power.
