Luthor creates grandiose engineering projects to prove his superiority over the superhero, but each one fails and causes problems that Superboy then solves. Luthor then makes his first attempt to murder the Last Son of Krypton and fails. Instead of bringing him to the authorities, Superboy declares they are even now and expresses hope Lex will "straighten out" and use his intelligence to help humanity rather than try to prove his superiority or waste time seeking power and vengeance.
