was the second person to serve in the Legion of Super-Heroes
under the name Invisible Kid.
Jacques acquired his power to turn invisible at will by using the serum invented by Lyle Norg, the original Invisible Kid. Foccalt had brought is little sister to Brainiac 5 for treatment of a rare disorder. During the treatment, Foccalt's sister was possessed by Computo, who took over Legion Headquarters. During the insuing battle, Foccalt took the invisibility formula to help in defeating Computo and saving his sister. Foccalt was offered membership in the Legion.
The invisibility serum reacted with Foccalt's unique body chemistry and gave him the ability to open holes in space that allowed him to instantly move from one place to another. Because Invisible Kid had no control over this power, it was deemed a danger and with the help of Brainiac 5, he underwent treatment to lose that ability.
