A member of the Legion of Super-Villains, an organization of super-criminals from the twenty-first century A.D. (later specified as the 30th century). A native, like his brother Garth (Lightning Lad), of the planet Amarta (also referred to as the planet Winath), Lightning Lord wears a red, white, and green costume with a pair of white lightning bolts emblazoned on his chest. Both brothers possess the â€œpower of super-electricity,â€ the ability to discharge controlled bolts of â€œsuper-lightningâ€ from their bodies. Lightning Lord's real name is Mekt Ranzz.
According to Superman No. 147/3, Lightning Lord and his brother acquired their awesome powers when, as youngsters exploring a wooded area on the planet Korbal, they were attacked by a fearsome â€œlightning monsterâ€ which had â€œthe frightful ability to transfer some of its lighting power to its victims ... like an infectious disease!â€ Lightning Lad vowed to devote his newly acquired powers to helping others and joined the Legion of Super-Heroes, while Lightning Lord decided to use his powers for crime and ultimately joined the Legion of Super-Villains.
In March 1962, while in the grip of a nightmare induced by exposure to Red Kryptonite, Superman dreams that Lightning Lord and other villains lure him into a trap, put him on â€œtrialâ€ for his alleged â€œcrimesâ€ against them, and sentence him to battle Supergirl to the death in a gigantic arena or else stand by helplessly while they blow up the Earth. These events, however, are all only part of a nightmare, and no actual confrontation with Lightning Lord and his cohorts ever takes place (Act No. 286: â€œThe Jury of Super-Enemies!â€) (TGSB).
Most later chronicles document that Lightning Lad's fraternal twin Ayala (Lightning Lass) was also present on Korbal and that a group of "lightning beasts" attacked the siblings. Ayala joined the Legion of Super-Heroes at a later date (first as Lightning Lass and later becoming Light Lass).
