During a later skirmish with Superman, Fine's body is irreparably damaged, leaving Brainiac with only a short time to live. With help from a new Coluan assistant named Prin Vnok, Brainiac retrieves Doomsday, the monster that seemingly killed Superman before, and uses him as a new host body. Now a cunning psychic with a super-strong, near-indestructible body, Brainiac attacks the Justice League. But Doomsday's own raging mind fights back and Brainiac realizes he still needs a suitable host. Hoping to create a clone Doomsday form by manipulating human DNA, Brainiac attempts to steal a prematurely born baby Superman is transporting to a Neo-Natal Intensive Care Unit, the newborn child of Pete Ross and Lana Lang. Brainiac sees this as an opportunity for revenge, correctly concluding that Ross and Lang are close to him. Using a 'psi-blocker' device, Superman thwarts Brianiac's plans and the villain is forced to house his consciousness within a completely robotic body. Dubbing his new form Brainiac 2.5, the villain fears he is now trapped in this form.
