Thousands of years ago, Steppenwolf and his army of Parademons attempt to conquer Earth through the combined energies of three Mother Boxes. They are foiled by a unified army that included the Olympian Gods, Amazons, Atlanteans, humans, and Green Lanterns. After repelling Steppenwolf’s army, the Mother Boxes are separated and hidden in locations around the world.
In the present, the world is in mourning after the death of Superman. This triggers the Mother Boxes to reactivate and Steppenwolf’s return to Earth in an effort to regain favor with his master, Darkseid. Steppenwolf manages to retrieve the Mother Box from Themyscira, prompting Queen Hippolyta to warn her daughter, Diana Prince, of Steppenwolf’s return by lighting the invasion fire. Prince joins Bruce Wayne in his attempt to unite the other metahumans, with Wayne going after Arthur Curry and Barry Allen, while Prince tries to locate Victor Stone. The two of them fail to persuade Curry and Stone but manage to recruit an enthusiastic Allen onto the team. Stone later joins the team after his father Silas is kidnapped, along with several other S.T.A.R. Labs employees, by Steppenwolf seeking to acquire the Mother Box from them.
