Justice League Giant was one of four Walmart-exclusive DC series that debuted in 2018. The series featured one original Wonder Woman story per issue, with the rest of the issue consisting of reprinted stories. The series was replaced in 2019 by Wonder Woman Giant.
The Wonder Woman feature story was subsequently re-printed in a standalone mini-series.
While guiding Diana and Etta to where Steve and his co-pilots went, Jonah states that he’s also searching for his friend Tallulah who was riding in a boat along with him, but they got separated after a storm. As it starts raining, Jonah directs them to a cave he used earlier and starts firing towards it mouth, in case some animal is taking shelter in it. Diana and Etta stop him, worrying he could harm their friends if they’re in there. As Diana goes to search inside the cave, Jonah gets attacked by an energy blast but is saved by Diana who gets knocked away by it.
As she goes after the attackers, Wonder Woman comes across a group of robots who talk about killing her and her accomplices to safeguard a princess. After she fails to reason with them, she is forced to destroy them and saves Etta from being killed by one of them. As Diana wonders about the person the robots were protecting, the princess Sibella comes out and reveals they were protecting her after Jonah’s bullets hit her body armor. She invites them into the cave but states she can’t remember anything asides from their names.
They spot surveillance footage of many parts of the island on monitors of the ship inside the cave and wonder whether they are recordings or live feed. Diana theorizes the place might have been used as a control center to run the island, though Sibella states she doesn’t remember anyone ever coming to the place. They look at Sibella’s chamber and Etta guesses she’s an alien. As a non-hostile robot shows up, Sibella orders it to tell how she landed here and who the ship belongs to, learning it was the same ship they are in and it’s stolen, but is denied access as to who stole it.
Jonah then calls upon Diana to show her the surveillance footage of Steve and his co-pilots cooking food. The robot states that is a live feed but is unable to determine their location. As she spots some bugs in the jungle on the video feed, Diana rushes to rescue Steve, Etta wonders what can cause her to run away because of some insects and Jonah tells her to view her the video feed again so she can observe the insects are actually giant in size.
In the middle of the parademon assault, a writer named David is trying to save his family, wishing for some help. His prayer is seemingly answered by a set of green fireworks on the horizon. The fireworks are part of the Justice League’s plan to fight Darkseid.
On Apokilips, Bruce Wayne sneaks through the building he is in, finding a pair of superbeings discussing the invasion of the Multiverse in search of Darkseid’s daughter, who was apparently kidnapped. The superbeings have Superman tied down before them, and they plan to clone him as part of the next generation of parademons.
On Earth, Cyborg uses his new machinery to tap into the Mother Box network. By saying the word, he is able to suddenly overload the system, causing teleport holes to appear all over the area – and on Apokilips. This shocks the two beings torturing Superman, and Batman uses the moment to free Superman, before the two escape back to Earth through the Boom Tubes. They try to trap Darkseid on the other side of a Boom Tube, but he grabs Superman. With seconds to spare, Cyborg works out how to shut down the network, seemingly killing Darkseid. The world is saved.
In the immediate aftermath, a crowd gathers around. The group thinks they are to be stoned, but instead they are cheered, hailed as the world’s greatest superhumans. Writing after the fact, Graves acknowledges the wording was off. The group were the world’s greatest super heroes. At a subsequent awards ceremony, the U.S. President gives a speech about how this team of heroes saved the world. Green Lantern is about to break ranks and say it was a one-time deal, but Batman stops him, pointing out that official sanction will get the GCPD off his back, the Air Force off Green Lantern’s and the Army off Superman’s. The President receives a message from an aide, to say there has been a disaster, and the group is needed. The Flash announces that they have a name, and tells the President to call them the “Super Seven.” The rest of the team hates this.
A writer named David Graves writes a book about them later, coining the term “super heroes.” In his book, Graves calls this team the “Justice League.” The book is titled “Gods Among Us” and the cover depicts them fighting a starfish-monster.
In London, a man with the shadow of a devil meets a man with glowing blue eyes. They discuss the fact that since the Justice League started, similar beings have become active: Green Arrow, Hawkman, Zatanna. The second man muses that if these are super heroes, then people like himself would be called super villains. As he lights a cigarette, we see he has a monstrous-looking lapel pin.
