Lightning Lad is a founding member of the Legion of Super-Heroes along with Saturn Girl and Cosmic Boy. Born on the planet Winath, he is the twin brother of fellow Legionnaire Ayla Ranzz (Lightning Lass), the younger brother of the supervillain Mekt Ranzz (Lightning Lord), and the father of two sets of twins; Sons Garridan (Validus) and Graym Ranzz and daughters Dacey and Dorrit Ranzz.
Early in the Legion's history, he sacrificed himself battling Zaryan the Conqueror, but was later resurrected by the sacrifice of Proty, Chameleon Boy's shapeshifting pet. However, a later retcon revealed that Proty's mind had actually taken over Lightning Lad's form.
An incident against a monster dubbed the "Super Moby Dick of space" resulted in the loss of Lightning Lad's right arm, which was replaced with a bionic appendage. He eventually had his arm regrown, but in the interim a criminal scientist used the situation to hypnotize Lightning Lad into acting as the super criminal Starfinger who used the bionic arm as a weapon. After the Great Darkness Saga, his son was abducted by Darkseid and he was subsequently transformed into the monster Validus.
During the "Five Year Gap" following the Magic Wars, Earth fell under the covert control of the Dominators, and withdrew from the United Planets. A few years later, the members of the Dominators' highly classified "Batch SW6" escaped captivity. Originally, Batch SW6 appeared to be a group of teenage Legionnaire clones, created from samples apparently taken just prior to Ferro Lad's death at the hands of the Sun-Eater. Later, they were revealed to be time-paradox duplicates, every bit as legitimate as their older counterparts. After Earth was destroyed in a disaster reminiscent of the destruction of Krypton over a millennium earlier, a few dozen surviving cities and their inhabitants reconstituted their world as New Earth. The SW6 Legionnaires remained, and their version of Lightning Lad assumed the code name Live Wire. Unlike the adult Garth, he did not possess Proty's mind or personality. Thus, the teenage Live Wire was far more reckless and rebellious than any previous depiction of Garth.
