Querl Dox is the third descendant of L.E.G.I.O.N. founder Vril Dox II of Colu.

Vril Dox II was used by his father Brainiac 1 to aid in the villain's human disguise on 20th Century Earth. Along with members of L.E.G.I.O.N., Vril Dox II liberated his home planet by elevating his intelligence to the twelfth level, two levels higher than the Computer Tyrants of Colu.

Querl Dox inherited his ancestor's intelligence and the title Brainiac. While on Earth at the Time Institute, Querl Dox played a major role in perfecting the Time Bubble, the 30th Century's primary mode of time travel. His invention brought him into contact with the Legion of Super-Heroes which he joined as Brainiac 5.
