, to arrive from the 64th century. Brainiac 13 began transforming Metropolis into the 64th century version of the city, which, apparently, he controlled. When it became apparent he was to be defeated by the combined efforts of Superman, Lex Luthor, and his own past self (now possessing the body of Luthor's infant daughter Lena), Brainiac 13 gave control of Metropolis to Luthor in exchange for Lena/Brainiac 2.5, whom he forced to help him escape.
He returned to Earth during the Our Worlds at War crossover, in which Earth and its allies fought a multi-front war against Brainiac 13 and Imperiex. Brainiac 13 claimed to be allying himself with Earth, but this proved to be part of a complex plan to regain control.
His chief aide was "Leniac", a green-skinned teenage girl with "control discs" on her forehead, suggesting the diodes of earlier Brainiacs (and identical to the forehead discs of the "upgraded" Brainiac 5.1 in the Legion of Super Heroes, and the Superman: The Animated Series version of the original Brainiac).
At the end of the war, Brainiac 13 and Imperiex were both sent back in time, becoming part of the Big Bang, and Brainiac 2.5 was expunged from Lena, who reverted to infancy, although the discs remained.
