Rather than spend life in prison, he is recruited by General [[Sam Lane (comics)|Sam Lane]] to serve out his sentence by working for the secretive Project 7734, accessing the knowledge stored within the captured [[Brainiac (character)|Brainiac]].<ref name="ac871">''Action Comics'' #871 (January 2009)</ref> Luthor successfully accesses Brainiac's brain, using it to activate the villain's ship and robotic drones. Luthor is then tasked with studying the genetic potential of the seemingly dead body of [[Doomsday (comics)|Doomsday]].<ref>''Action Comics'' #873 (March 2009)</ref>

Luthor later manages to use Brainiac's ship to kill the soldiers assigned to watch him. Brainiac frees himself from Luthor's control and the two make their escape.<ref>''Adventure Comics'' #0</ref> Forming an alliance, Brainiac promises Luthor can have Earth when he is done with it. Lex returns to Smallville, where it is revealed his sister Lena is alive, physically and mentally handicapped, and living with her daughter Lori. In an effort to prove his abilities to Superboy, Lex manages to counter Lena's disabilities, allowing her to walk and regain greater mental awareness, then quickly reverses the process, leaving her completely catatonic. Luthor then informs Superboy that so long as Superman is alive, he will never reveal how he helped Lena. Seeing Superboy now as a failed experiment due to having 50% "wrong alien DNA", Luthor and Brainiac create another binary clone with their own genetics.<ref>''Adventure Comics'' #5–6</ref>
