Lex Luthor's childhood is fleshed our further in the pages of Justice League. Before he ever met Clark Kent, it is said his father Lionel Luthor was a scientist working with the Legionnaires Club, an organization created by the immortal villain Vandal Savage to unlock the secrets of the universe. At one point, Lionel is able to reach through space and time to bring a Martian child named J'onn J'onzz to Earth. Lex and J'onn form a brief friendship. When the heroic Blackhawks attacks the operations of the Legionnaires' Club, Lex sends J'onn back home to Mars to protect him. Many years later, he will meet J'onn again when the alien operates on Earth as the Martian Manhunter. To protect his secrets, Vandal Savage has Lionel's memories altered. As a result of this psychological trauma, Lionel becomes a "broken man" and an alcoholic. Lex comes to hate his father and only feels family love for his sister Lena, who is increasingly ill and whom he wishes to help.
