Lexbots were a dangerous form of household robot, designed by Lex Luthor in the book 'It's Superman!' by Tom DeHaven.

The robots were sold on the open market as safe household assistants, who could help out with daily chores. However, the robots were secretly deadly and programmed to kill.

Superman's first battle as Superman was his final confrontation with a Lexbot. At first, he found the battle difficult, not being used to his powers. However, he soon overcame the robot and put an end to Luthor's evil schemes.
