LEX is a police robot created by professor Ignatz Mindbender in the episode "Leonardo, the Renaissance Turtle" from the 1987-1996 animated TV series. He was programmed by Mindbender to arrest and punish even minor law infractions, and manipulated REX-1 to attack Leonardo and April O'Neil. LEX is deactivated by Mindbender after Leonardo tricked the robot into arresting its creator.
