Zack Snyder's Justice League
Diana informs Bruce Wayne, and as the two are trying to form a team of superheroes in Superman's absence, they realize they need to act fast with Steppenwolf trying to recapture the Mother Boxes. Though Bruce had failed to recruit Arthur Curry, he finds Barry Allen and gets him to join, but Diana is unable to convince Victor Stone to join until Victor's father Silas is kidnapped by the parademons and brought to Steppenwolf. Meanwhile, Arthur is convinced to help the Atlanteans guard their Mother Box. He manages to save Mera when Steppenwolf attacks the outpost but is unable to prevent the alien from taking the second box.  Victor arrives in time to help Bruce, Diana, and Barry rescue several S.T.A.R. Labs scientists, including Silas, from an underwater building where Steppenwolf is questioning them about the final Mother Box's location. Though they fight Steppenwolf off, the building is flooded and they are only saved when Arthur arrives and stops the water from reaching them.
