Zach Schneider's version of justice league

Thousands of years ago, Darkseid led an army of demons to try to conquer the Earth using the transformation power of the three mother boxes, and the Green Lantern, the Old God of Olympus, the Amazons, atlantes, and humans successfully joined forces to repel Darkseid, and the three mother boxes were separated and hidden in different places. Now, the death of Superman has revived and signaled the MotherBox, causing Darkseid's subordinate Steppenwolf to descend to Earth with demons. Steppenwolf wants to form the Mother Box into a "Trinity" to conquer Earth, hoping to end the exile and regain Darkseid's favor.

Steppenwolf first retrieves the first mother box from Paradise Island, and Queen Hippolyte lights a beacon to warn her daughter diana Prince of the human world, who informed Bruce Wayne of the incident after stopping a court bombing. In order to fight the impending threat, Bruce has been trying to recruit superhumans like Arthur Curry, but everywhere he runs into obstacles, only Barry Allen is willing to join, his father is serving a prison sentence, Barry works to pay the tuition for the criminal science, and accidentally uses his superpowers to save a girl in a car accident. Diana, on the other hand, finds Victor Stone/Steel Bone, who was in a car accident with his mother after a rugby match, and his mother died, and he was revived by his father, Silas Stone, using the power of the mother box. Victor initially refused to join the Alliance until his father and several Star Lab employees were kidnapped by demons. Meanwhile, Steppenwolf attacks the fortress of Atlantis, successfully repelling Maela and Arthur and retrieving the mother box.

Bruce and the others learn of Steppenwolf's location in Director James Gordon's intelligence, and all of them rush to the location to fight Steppenwolf and rescue the hostages, but Steppenwolf destroys the tunnel and floods in, and Arthur appears in time to delay the flood so that they can escape. Victor brings with him the last mother box, which is called a "transformation machine", which ignores life and death and rules, and only destroys or rebuilds things according to the needs of the owner. The Alliance decided to use the Mother Box to resurrect Superman to help them resist the Steppenwolf invasion. The crowd exhumed Superman's body and arrived at the Kryptonian spaceship in the Star Lab to revive it. Victor, when activating the device, accidentally sees the + world destroyed by Darkseid, the deaths of Diana and Arthur, and the future vision of Superman surrendering to Darkseid by losing Louise Lane, and is ready to stop, but Barry successfully activates the mother box with the current generated by moving at high speed under unknown circumstances, and Superman is resurrected. The newly resurrected Superman's memory and consciousness are confused, and he fights with everyone, and just as Bruce is attacked, Louise arrives in time to pacify Superman. With the help of his girlfriend, Superman recovers his memories through convalescence and is reunited with his mother, Martha.

Steppenwolf breaks into the Star Lab to retrieve the last mother box, and Silas sacrifices his life to heat up the mother box, allowing Victor to track the location of the mother box through heat energy. Using satellite positioning, the five men traveled to Putanov, an abandoned ghost town in Russia where Steppenwolf was hiding, to prepare for war with him. Superman, on the other hand, returns to Krypton's reconnaissance ship to change into a new black outfit and asks Afu about his resurrection. Although Victor came into contact with the bound mother box, the crowd could not delay Steppenwolf so that he could not separate the mother box; at the same time, Superman in black clothes arrived and defeated Steppenwolf, but Barry was shot by a demon and could not reach Victor in time to provide him with power, so that the mother box was successfully integrated, thus decomposing everything on Earth and about to transform into an apocalyptic star. Barry had to use Divine Force to reverse time, allowing Victor and Superman to separate the mother box in time. Arthur pierces Steppenwolf with a trident, and Superman sends him flying before being beheaded by Diana, who after confronting an enraged Darkseid, tells his military master, Desard, that he will personally set out on Earth to capture the long-awaited anti-life equation.

After the battle, Bruce, Diana, and Afoe Pennyworth decided to convert the abandoned Wayne Manor into the Hall of Justice for more future members of the Alliance. Diana also receives messages from her hometown; Barry informs her father that Henry has taken a job in the Central City Penal Department; Victor listens to his father's messages and acts of good in his own strength; Arthur bids farewell to Maela and mentor Nudis Vulko and says he is going to see his father; Superman resumes his daily life and continues his work as a journalist, while Bruce redeems Superman's house from the bank.

Escaping from the Arkham Psychiatric Sanatorium, Lex Luthor hopes to recruit Slade Wilson, who wants to kill Batman on the grounds of a "personal vendetta", and Rex reveals Batman's true identity. Bruce, on the other hand, dreams of another scenario: the surviving Barry, Victor, Maela, and Wilson reluctantly team up with the Joker to confront the controlled Superman in a world destroyed by Darkseid. Bruce suddenly wakes up to find a Martian manhunter visiting, and he has disguised himself as Martha to comfort Louise. Martian Manhunters endorses Bruce's formation of a coalition and wants to keep in touch with him to deal with darkseid's threat.
