During the "Final Crisis" crossover, a group of teen supervillains calling themselves the Terror Titans begin abducting teenaged metahumans to use as competitors in the Dark Side Club, an underground arena where the young heroes are brainwashed and forced to fight to the death for spectators and wealthy patrons. After learning of the abductions, Terra goes on the run, eventually meeting up with fellow teen superheroes Aquagirl, Molecule, Offspring, Zachary Zatara, and the Star-Spangled Kid. While deciding on a course of action, the teens are ambushed by the Terror Titans, who proceed to overpower and capture them, killing Molecule in the process. Atlee and the others are taken to the Dark Side Club and subjected to the Anti-Life Equation, which causes them to become slaves to Darkseid and his cadre of followers. After winning several matches in the tournament, Terra is made a member of the Clock King's Martyr Militia, a team of brainwashed superhumans he plans to use on an attack in Los Angeles. Atlee and the others are ultimately freed from the Anti-Life Equation when Miss Martian, Rose Wilson, and Static lead a rebellion against the Terror Titans and capture the various members of the Dark Side Club.
