After the Source Wall was shattered, four entities known as the Omega Titans began invading Colu, forcing Brainiac to summon the Justice League for help. But as Amanda Waller and the new Task Force XI destroy him, his great-great-grandson Brainiac 5 informs the League that Brainiac was using them to make sure the Omega Titans would destroy Earth, so there can be no interference for him. Over time, Lex Luthor found a mysterious object related to an unknown force known as the Totality, while forging a new Legion of Doom, which includes a revived Brainiac and The Batman Who Laughs. The Totality is presumed to be linked to Perpetua, an ancient goddess who was made to vanish by her three children, the Monitor, the Anti-Monitor and the World Forger. After faking his death through a bombing and with Perpetua's help, Luthor manages to transform himself into a human/Martian hybrid version of himself called "Apex Lex".
