In the Post-"Crisis" DC Universe, Brainiac's history was completely rewritten. The Post-"Crisis" version of Brainiac was now a radical Coluan scientist called Vril Dox who, having attempted to overthrow the Computer Tyrants of Colu, was sentenced to death. In his last moments before disintegration, his consciousness was attracted light years away to Milton Moses Fine, a human sideshow mentalist who worked under the alias "The Amazing Brainiac". Needing cranial fluid to maintain his possession of Fine, Dox went on a murder spree. He discovered that Fine had genuine psychic powers and was thus a metahuman, which he frequently wielded against Superman.
