Fictional biography
Lightning Lad
Lightning Lad is a founding member of the Legion of Super-Heroes, along with Saturn Girl (whom he later married) and Cosmic Boy. He is the twin brother of fellow Legionnaire Lightning Lass, the younger brother of the supervillain Lightning Lord, and the father of the monstrous Validus.
Early in the Legion's history, he sacrificed himself battling Zarquam the Conquerer, 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.
Live Wire
In post-Zero Hour rebooted continuity, he is a teenager again, with the code name Live Wire, and he is no longer the husband of Saturn Girl (although they are still romantically involved) or the father of Validus.
In current continuity, he was apparently killed during the Legion Lost storyline, in battle with "The Progenitor" (actually an insane Element Lad) but actually was "stored" in Element Lad's crystalline body. He now has Element Lad's transmutation powers, in addition to his electrical ones.
