Many years later, Brainiac 5 was approached by Jacques Foccart, a teenage native of Earth from what was once the francophone African nation of Côte d'Ivoire. Jacques' younger sister Danielle was suffering from a life-threatening neurological disorder which had baffled the best medical experts of the 30th century, and Jacques took her to Brainiac 5 as a last resort. Brainiac 5 rashly decided to utilize a piece of circuitry from the dismantled machine Computo, a highly advanced supercomputer he had created years earlier. Computo promptly possessed Danielle's body. Computo took control of Legion headquarters and the city of Metropolis and nearly killed several Legionnaires. In order to save Danielle and the others, Jacques drank Lyle Norg's serum and gained the power of invisibility. Immediately thereafter, the Legion voted Jacques onto the team as its newest member. He took the name Invisible Kid in honor of Lyle.
