In Justice League, the superhero team forms to honor Superman following his death and to save the planet from the catastrophic threat of Steppenwolf and his army of Parademons.
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 in the palace. 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.
