Zack Snyder's Justice League
Thousands of years ago, Apokoliptian warlord Darkseid and his Parademons attempt to invade Earth using the combined energies of the three Mother Boxes to harvest the Anti-Life Equation, a secret power capable of controlling all of existence. Darkseid is foiled by a unified alliance of the Olympian Gods, Amazons, Atlanteans, humanity, and extraterrestrial beings.[c] The Mother Boxes are then separated and hidden in different locations. Millennia later, Superman's death following the battle with Doomsday reactivates the Boxes, attracting Steppenwolf, Darkseid's disgraced lieutenant. Steppenwolf aims to regain Darkseid's favor by gathering the Boxes to form "The Unity," which would instantly devastate Earth and terraform it into a copy of their homeworld.
Steppenwolf reaches Themyscira through a portal and fights to obtain the Amazons' Mother Box. Diana Prince informs Bruce Wayne, as the two seek to form a team of metahumans[d] to protect the planet. After failing to recruit Arthur Curry, Bruce locates Barry Allen, who enthusiastically joins. Diana locates Victor Stone, who joins after his father, Silas, and other S.T.A.R. Labs employees are kidnapped by Parademons seeking humanity's Mother Box. Steppenwolf kills Atlantean guards and takes their Mother Box, forcing Arthur to join the group. Victor retrieves the last Mother Box, which he had hidden. He reveals it was used to rebuild his body after a car accident, explaining that the Boxes can rearrange matter. The group realizes they could resurrect Superman using the Box.
The team exhumes Clark Kent's body and places it in a Kryptonian ship.[e] They successfully resurrect him, but Clark fails to remember who he is and attacks the group. Lois Lane arrives and placates him, then takes him to Clark's family home in Smallville, allowing him to regain his memories. Steppenwolf retrieves the last Mother Box, but not before Victor's father sacrifices himself to supercharge it with laser heat, allowing Victor to track it. Without Superman, the five heroes travel to an abandoned Russian city called Pozharnov, where Steppenwolf aims to form the Unity.
They fight their way through the surrounding Parademons, with Superman arriving in time to subdue Steppenwolf. However, Victor fails to prevent the Unity and the planet begins to be destroyed. To reverse time in order to provide Victor the necessary charge, Barry enters the Speed Force, allowing him and Superman to prevent the Unity. Working together, the team kills Steppenwolf. Darkseid vows to return to Earth for the Anti-Life Equation. In the aftermath, Bruce and Diana make plans to set up a base of operations for the newly formed alliance at the desolated Wayne Manor. Clark resumes his double life in Metropolis, with Lois implied to be pregnant with his child. Arthur meets with Vulko and Mera before going to see his father,[f] and Barry informs his erroneously convicted father in prison that he has acquired a job in Central City's police department. Victor is inspired by a message left by his father to realize his purpose in life.
Later, Lex Luthor, who has escaped from Arkham Asylum, is visited on his yacht by Slade Wilson, to whom he reveals Batman's secret identity while Bruce awakes from an apocalyptic dream of the future,[g] in which his ragtag resistance troop is hunted by a mind-controlled Superman, and receives a visit from the Martian Manhunter, who promises to help prepare for Darkseid's return.
