Brainiac 5
Brainiac 5
Originally thought to be the descendant of the original Brainiac, Brainiac 5 is actually descended from Brainiac II (Vril Dox), who was adopted by Brainiac I to hide his origin.
Brainiac 5 (real name: Querl Dox) is a member of the Legion of Super-Heroes in 30th Century Metropolis (Act No. 276/2, May 1961: "The Three Super Girl-Friends"; and others). Possessed of a 12th level intelligence common to his homeworld of Colu, his many inventions have included the Legionnaires' time-traveling bubble, the best cure for Mon-El's lead poisoning, flying belts, flight rings, and Computo.
Both Supergirl and Brainiac 5 apply for Legion membership at the same time but Supergirl is rejected as Red Kryptonite has turned her into a "Superwoman" and over the 21-year age limit for membership (Act No. 276/2, May 1961: "The Three Super Girl-Friends").
As depicted in the chronicles repeatedly, Brainiac 5 and Supergirl are sweet on each other. (TGSB)
Note: the original future timeframe of the Legion of Super-Heroes is chronicled as the late twenty-first century, hence only four generations separated Brainiac 5 from his namesake "ancestor." The bulk of the Legion stories are firmly placed in the 30th century, and the character's name is unchanged.
