The fallout from METAL continues as the evolutionarily perfected Lex Luthor serves as a John the Baptist for the goddess Perpetua, paving the way for her conquest of everything. Only one person stands in his path -- The Batman Who Laughs, the evil Joker-fied Batman from the Dark Multiverse. TBWL has spread the dark infection to six heroes, five of whom attack Luthor at his safehouse -- which turns out to be one of his employee's apartments he long ago modified without her knowledge.
Lex is not only outnumbered, but he's up against the powers of Kara Zor-El (Supergirl), King Shazam (Shazam), Deathbringer (Donna Troy), Sky Tyrant (Hawkman), and Scarab (Blue Beetle). Anyone else would give up, but Luthor -- who was already the smartest man alive before his augmentation -- has already defeated all five of them while they were posturing. It's all over except for the actual doing of it, which proves to be simplicity itself.
