Justice League (2017 PG13)

Steppenwolf and his legions of Parademons attempt to take over the Earth using the combined energies of the three Mother Boxes. The attempt is foiled by a unified alliance including the Olympian Gods, Amazons, Atlanteans, humanity, and extraterrestrial beings. The Mother Boxes are separated and hidden in different locations. Thousands of years later, Superman’s death following the battle with Doomsday reactivates the Boxes, attracting Steppenwolf again to Earth. He aims to gather the Boxes to form “The Unity”, which would instantly devastate Earth and terraform it into a copy of his homeworld. Steppenwolf retrieves one Mother Box from Themyscira, prompting Queen Hippolyta to warn her daughter Diana. Diana joins Bruce Wayne in an attempt to unite other metahumans to their cause: Wayne goes after Arthur Curry and Barry Allen, while Diana locates Victor Stone. Bruce fails to persuade Arthur but finds Barry enthusiastic. Victor joins after his father Silas and other S.T.A.R. Labs employees are kidnapped by Steppenwolf, who is seeking the Mother Box protected by humanity.
