Cyborg uses his metallic powers to single handedly apprehend Lex Luthor. The Super Powers Team is so impressed, they invite him to join the team, but Cyborg declines. Firestorm, who would like have someone his own age on the team learns about Cyborg, how he came to be and that he only wants to be left alone. The metallic hero reluctantly winds up working with the Super Powers Team when they discover giant seed pods that Darkseid's Parademons have placed all over the Earth. The seeds will sprout and crack the Earth's crust and eventually will change Earth into a second Apokolips. To stop Darkseid's plan, Cyborg reluctantly accompanies Wonder Woman and Firestorm to Apokolips to find the source of the seeds and destroy them. In the end, Cyborg finally joins the team.

While being pursued by Darkseid in space, Superman, Firestorm, and Cyborg take shelter in a gigantic space ship. They discover a female being who seems to cast her image all over.

Superman's powers are cut in half due to the orange sun in the galaxy they are in.

He insists that before Bizarro #1 takes them back, they need training as Super Heroes and with their backwards minds, they wreak havoc on Earth.

The Super Powers Team has to search for Col. Steve Trevor, Wonder Woman's love interest who vanishes, but he shortly reappears and returns to Earth with no one knowing that Col Trevor has been captured and replaced by Darkseid who uses a molecular reconfigurator to impersonate Col.

So our heroes have two people to rescue and a satellite to retrieve.

The Scarecrow is plaguing Gotham City with his fear transmitters, but he has to contend with Batman and Robin, Gotham's Guardians. Batman has always been known as the man with no fear, but when he chases the Scarecrow into a certain alley, he is paralyzed with terror. The alley is none other than Crime Alley where years ago, Bruce Wayne witnessed the murder of his parents and guided his destination to becoming Batman. The Scarecrow plans to take advantage of this and captures Robin and Wonder Woman and uses them as bait to set a trap for Batman. The Caped Crusader now has to not only battle the Scarecrow, but his own fear as well.

With their new powers, they are able to capture Superman, Wonder Woman, and Firestorm. Ace is in cohoots with Darkseid, and things really get wild when Batman, Robin, and Cyborg raid their hideout. Batman also discovers that Ace is really his arch foe, the Joker, a rather unlikely foe to team up with Darkseid.

Darkseid sees great opportunity to take over Star City, the first city in space built by Japanese billionaire Industrialist Dr. Moko. When Batman, Samaraui, and Firestorm journey up to the city, they and Moko's daughter are unaware that Moko has been captured and replaced by a robot duplicate. Meanwhile, Superman and Wonder Woman join Aquaman who has found an odd island which is not only Darkseid's base of operations, but a trap set for them. Batman, Samaraui, Firestorm, and Moko's daughter are forced to flee through Star City with the robot workers being contolled by Kalibak and Desaad. Their only chance is to cut off the power and black out the city.
