Although they do not appear in Justice League: War, the Olympian Gods are briefly mentioned by Wonder Woman during a conversation with Superman about the other five heroes, referencing Batman as Hades (who is just as dark and mysterious just as Maxie Zeus did in the "Fire From Olympus" episode of Batman: The Animated Series), Green Lantern as Apollo (the God of Light), Flash as Hermes (the Messenger of Olympus and God of Speed), Cyborg as Hephaestus (the Blacksmith of Olympus and God of Metal) and Shazam as Zeus (God of Lightning).
While Diana stood admiring the replica, Bruce Wayne appeared. He proceeds to angrily confront her by grabbing Diana's arm and asking her about the information device that she had stolen. Bruce claims to see right through her "babe in the woods" act, saying that while Diana doesn't know him, he's met "a few women like [her]". Diana, however, calmly smiles and retorts that Bruce has never met any women like her. She then proceeds to tell Bruce that she was unable to obtain anything from Bruce's device, due to Lex Luthor's data having military-grade encryption. Diana explains her intention to re-obtain her photograph from Luthor, stating that she only borrowed Bruce's device, and has already returned it to him shortly beforehand (placing it into the glove compartment of his car), before calmly excusing herself and leaving.
As Diana, Victor and Arthur all try to simultaneously flank Superman (albeit unsuccessfully), Barry attempts to help using his speed, but Superman is able to see him and keeps up with the speedster. Despite Barry's best efforts, Superman is able to land a glancing blow, knocking him out before Batman arrives and gets Superman to stop. Wonder Woman tries to fight Superman again, yet she's knocked down. He then swats Batman and asks him the same question that Bruce asked him "Tell me, do you bleed?". Before Superman could kill Bruce, Lois and Alfred to stop him.
