Brainiac 4 is the fourth Coluan of the super-intelligent Brainiac legacy, alive in the 30th Century. Like all Brainiacs, he is from the planet Colu and has an incredible twelfth-level intellect. Lyrl Dox is his predecessor, and Querl Dox is his successor. His son would go on to become a member of the Legion of Super-Heroes. The name has also been associated with the Dark Circle. Brainiac 4 was created by Edmond Hamilton and John Forte, first appearing in Adventure Comics #335. (1965)
