Justice League of America, Vol. 1 #147 (1977)

Crisis In The 30th Century
The Justice Society members are visiting the Justice League briefly, following their battle against the Psycho-Pirate, when a gigantic magical hand plucks five members from each team out of the satellite, and into the year 2977, where they become pawns of Mordru the Magician, arch-foe of the Legion of Super-Heroes. Mordru has recently captured five Legionnaires, he holds hostage until their comrades have secured for him the three mystic artifacts necessary to free the ancient demons, Abnegazar, Rath, and Ghost. The Legionnaires having failed to return from their missions, the sorcerer now enlists the JLA and JSA heroes to do his bidding, while adding Green Arrow and Black Canary to his group of hostages. Superman, Dr. Fate, and Hawkman of Earth-2 rescue Sun Boy and Wildfire, and secure the Silver Wheel; Batman and the two Green Lanterns aid Brainiac 5 and Princess Projects in attaining the Green Bell; and Power Girl and the Flash of Earth-2 use their super-speed to enter a limbo-like realm and regain the Red Jar. Mordru then uses the objects to awaken the three demons, but the evil trio turns on him, and overpowers him.
