Invisible Kid

Following the Zero Hour Legion reboot, Lyle Norg was still alive and serving with the Legion. As well as a brilliant chemist, he was also a professional spy at a young age. He invented the invisibility serum while in Earthgov Intelligence's spy school. Rather than his scientific aptitude resulting in his getting on well with Brainiac 5, they had more of a rivalry. While Querl was more intelligent, Lyle had more imagination, being quicker to see unexpected applications for discoveries.

He was the de facto leader of the Legion Espionage Squad, consisting of himself, Chameleon, Apparition, Triad, and Shrinking Violet, and was instrumental in bringing down the corrupt administration of United Planets President Chu.

Lyle served one term as Legion Leader; during his tenure, this version of the Legion defeated Mordru in their first and only battle with the sorcerer.

According to The Definitive Guide to The Characters of the DC Universe (2004), he was in a homosexual relationship with Condo Arlik. This, however, was never stated explicitly in the comic itself and never developed.

Lyle Norg is a genius with a skill for xenochemistry who was used by his father to develop an invisibility serum. His Science Police officer father used to bring him alien cell samples nearly every night to experiment with. By the time he had successfully created a serum, he discovered that his father promised to hand over Lyle's research to the Science Police all along. So he injected the only existing serum into himself and lied about it before contacting Brainiac 5 for help. Brainy invited Lyle to join the Legion. Eventually his father discovered the truth and tried to get Lyle to quit and hand over the serum. After the Legion was outlawed, Lyle reneged and produced a blood sample for his father to use. The sample was encoded with a monitoring virus allowing Legion access to the United Planets systemworks. Because of his relationship to Brainiac 5 his teammates have snarlingly nicknamed him "Brainiac 6".

When Lyle betrayed Cosmic Boy's trust by revealing to Brainiac 5 that several members had broken into Brainy's lab, he lied to the team by blaming everything on Shrinking Violet. He and Violet, who prefers the moniker Atom Girl, have since made a deal to continue the ruse, but his teammates still have a hard time trusting him. When Supergirl mysteriously appeared in the 31st century, Lyle, along with half the male Legionnaires vied for her attention. However, Lyle convinced Cosmic Boy that he did not have a crush on Supergirl to remove the competition for her affections. He recently had his arm torn off when his flight ring exploded, and was given an alien arm to replace it by a member of the Wanderers. He is left in Metropolis, the doctors reproducing his DNA to give him another arm.

His arm apparently healed, he returns to the active roster to save a young Tritonian mutant, Gazelle, for whom he carries a torch from then on.[9] During an invasion of aliens hailing from cyberspace, a small squad of legionnaires, including him and the recently appointed Gazelle, are digitized and sent into their home base: Invisible Lad has a customized avatar issued by Brainac 5, with a bulkier and more handsome physique that greatly impresses Gazelle. His idealized body is shown to be a trojan horse able to give Brainiac 5 complete mastery over the alien, digital universe. Invisible Kid, Gazelle and the other legionnaires spend some time trapped in cyberspace, while Brainiac 5 restores their physical bodies, damaged in a skirmish between the Coluan and some physical avatars of the invading aliens: in that week, Invisible Kid admits his feelings for Gazelle who happily reciprocates. Upon returning to the physical world, they both witness Brainiac 5 and Nura Nal exchanging their nuptial vows and inviting them to their marriage.[10]

The events of the Infinite Crisis miniseries have apparently restored a close analogue of the Pre-Crisis Legion to continuity, as seen in "The Lightning Saga" story arc in Justice League of America and Justice Society of America, and in the "Superman and the Legion of Super-Heroes" story arc in Action Comics. Lyle is depicted as a member of this version of the team in Justice Society of America (vol. 3) #5 (June 2007), and Action Comics #858 (late December 2007), but this incarnation of the Legion shares roughly the same history as the original Legion up to the events of Crisis on Infinite Earths.[11] Therefore, this version of Lyle is presumably deceased.

During the "Five Year Gap" following the Magic Wars, the Legion disbanded and Earth's government fell under the covert control of the Dominators, who had attempted to conquer the planet in the 20th century. Earth withdrew from the United Planets, and the government gradually became more repressive. Jacques became the leader of a resistance cell which included himself, Tyroc, and the former members of the Legion of Substitute Heroes. He became romantically involved with Drura Sepht, a Substitute Hero who once called herself Infectious Lass. He successfully led the resistance to victory over the Dominators, along with the unlikely assistance of former Legion foe Universo and the members of the Dominators' highly classified "Batch SW6".

At the time, Batch SW6 appeared to be a group of teenaged Legionnaire clones, created from samples apparently taken immediately following the team's first encounter with Universo.[14] Later, they were revealed to be time-paradox duplicates, every bit as legitimate as their older counterparts. In any event, the emergence of the SW6 Legionnaires allowed Jacques to meet their leader—the real Lyle Norg—for the first time.

After the defeat of the Dominators, Jacques became a planetary hero. The people of Earth rewarded his efforts by making him president of the planet, with Troy Stewart (Tyroc) serving as vice president. But soon thereafter, Earth was destroyed in a disaster reminiscent of Krypton's destruction over a millennium earlier.[15] A few dozen cities and their inhabitants survived, and the planet was reconstituted as New Earth. Eventually, Jacques resigned as president to rejoin the Legion (where he served as co-leader with Rokk Krinn), and Troy ascended to the presidency.

After Legion continuity was completed rebooted by the events of Zero Hour, Jacques was recast as a close friend of Lyle Norg from their days in school. Jacques was forced by Charma, a fellow student who had developed mind control abilities, to drink Lyle's serum as a test to see if it would be safe for her. Jacques was believed to have been killed by the serum, as Lyle had calibrated it to only work with his physiology. In truth, he was saved by the Intelligence Division. The serum worked differently for him than for Lyle, granting him the ability to become undetectable by any means, though this ability causes him severe pain to use. He continued to work for EarthGov's Intelligence. Some time after Lyle joined the Legion, Jacques would later save Lyle from Charma, though he could not reveal that he still lived.[16]

Jacques has not appeared in the "Threeboot" Legion continuity which began in 2005. However, the events of the Infinite Crisis miniseries have restored a close analogue of the Pre-Crisis on Infinite Earths Legion to continuity, as seen in "The Lightning Saga" story arc in Justice League of America and Justice Society of America, and in the "Superman and the Legion of Super-Heroes" story arc in Action Comics. Jacques is included in their number. The events of the "Five Years Later" era (including Jacques' rise to the presidency of Earth) are no longer part of mainstream DC continuity.
