Kajz Dox aka Brainiac 4 is a brilliant scientist hailing from the planet Colu.

He is father of the famed super-genius Brainiac 5 (Querl Dox). Kajz Dox dies on the planet Colu when his son Brainiac 5 is still a young boy. Pulsar Stargrave once claimed to be the father of Brainiac 5, but this is later proven false. The death of his father is one of the main reasons he joins the Legion of Superheroes.
