ORIGIN

Now you see me, now you don't !

The sentient but evil Computo then attacked the Legion using their own headquarters as a weapon and almost destroyed them. But Brainiac 5 remembered that Jacques, whom Computo had ignored, was still free in Legion headquarters. Using the Legion's telepathic plugs, he instructed Jacques to find a vial of the Lyle Norg's invisibility serum and drink it. This enabled Jacques to sneak up on Computo and inject his sister with a tranquilizer that neutralized Computo. For his bravery, Jacques was rewarded with Legion membership as the second Invisible Kid.

Not long after using Norg's serum, when Jacques went to another dimension; he met a person who appeared to be Lyle Norg. This "Lyle" went back to Earth with Jacques, but he was revealed to be the Dream Demon — master of that dimension. After defeating the creature, Jacques and Wildfire lit an eternal flame on Shanghalla as a tribute to Lyle.

Jacques found that not only could he turn invisible he could also teleport. He found this out when he teleported a Wharlik and himself into space. This power also caused his journey to the Dream Demon's dimension, but he did not know it at the time. Though teleportation was a powerful addition to his worth as a Legionnaire, Jacques could not in good conscience keep a power he could not control. He asked Brainaic 5 to analyze his powers, and ultimately asked the Legion's Dr. Gym'll to remove them permanently.
