Following the reboot of the Multiverse at the end of " Dark Nights: Death Metal " as seen during the " Infinite Frontier ", Earth-3 is recreated with a new version of Alexander Luthor. This version is a non-superpowered African-American man who wears a suit of high-tech armour. He is the sworn enemy of Ultraman, the self-appointed ruler and "protector" of Metropolis, and one of the few people with the courage to defy him directly. He is depicted as well intentioned and compassionate but largely ineffectual. He is horrified when Earth-3's evil metahumans are hailed as heroes for defeating the invading Starros. Aided by former Emerald Knight Thaal Sinestro and a New God named Lonar, he begins recruiting good metahumans into a Legion of Justice. Most of the group is defeated and Luthor is imprisoned by Ultraman.
