The Story: "The Battle At The Edge of Forever!" by Gerry Conway, Dick Dillin, and Frank McLaughlin. Continued from last issue, two different aliens use their transporter beams to move both Despero and the JLA (inside Hawkman's Thanagarian spaceship) to a sort of antechamber.
Despero takes on the JLA(wondering who the "fool-hardy freak" attacking him is--Elongated Man having joined after the last time they fought Despero), and realizes that the heroes he has imprisoned on his ship are not the real ones.
The two aliens act as though this is a game, and start transporting different JLAers all over to fight Despero, and when he defeats them they just move down the line.
It's Supergirl who figures out when, after she's knocked Despero silly, he keeps fighting, that he and they are under someone else's control. On an asteroid chunk, she confronts the two alien game masters and demands that they each pick a side, and whoever wins wins, ending this game. And even though the aliens have given Despero a force-field which shields him from harm, Supergirl throws him into orbit around the asteroid and meets up with him here:
...force-field or no, I don't know how this punch didn't reduce Despero into a pile of magenta-colored pulp.
The two aliens--the lone survivors of their race--end the issue beating each other up, still fighting over who won the bet.
Roll Call: Superman, Batman, Wonder Woman, Atom, Hawkman, Elongated Man
Notable Moments: Supergirl guest-stars again, in a kind of confusing story--the two aliens, tall and lean, from last issue, seem to be the story's protagonists. And then with this issue it shifts to two other aliens, also tall and lean.
The letter page mentions that Martin Pasko is hard at work on a story where the JLA takes on The Joker, to appear in The Joker #10, which was never published, the book being cancelled with #9. I wonder how far this story got to being completed...
