They cause trouble for Superman and finally an illusion cast by Saturn Queen succeeds in luring him to a planetoid, where a Kryptonite field holds him.
Pre-Crisis, the Legion of Super-Villains was founded by Tarik the Mute, who had suffered irreparable damage to his vocal cords during a battle with the Science Police and subsequently developed a pathological hatred of law and order.
He founded a school for supervillains, which served as the headquarters and recruiting grounds for the Legion's first incarnation, and blackmailed Colossal Boy into joining as a teacher.
[16] Manifestations of the LSV based on the nightmares of Dream Girl appeared at the end of Justice Society of America vol.
Spider Girl is now in a relationship with Earth-Man, the League's leader, and traded the Legionnaire White Witch to Mordru, in return for his staying off the planet.
Roy now has to wear a containment suit, since his radioactive powers have caused him to develop tumors all over his body, specifically one dominating the right side of his face.
[17] This incarnation of the Legion includes Lightning Lord, Saturn Queen, Cosmic King, Sun Emperor, Beauty Blaze, Ol-Vir, Tyr, Zymyr, Hunter, and Chameleon Chief as well as other Legion of Super-Heroes villains Black Mace, Universo, Dr. Regulus, Grimbor the Chainsman, Mordru, Esper Lass, Magno Lad, Micro Lad, Echo, Terrus, the League of Super-Assassins (Silver Slasher, Lazon, Neutrax, Mist Master, and Titania), the Fatal Five (Tharok, Emerald Empress, Persuader, Mano, and Validus), and the Justice League of Earth (Radiation Roy, Tusker, Spider Girl, Golden Boy, Storm Boy, and Earth-Man).
The Legion of Super-Villains later appear on Sorcerer's World as Mordru is trying to stop Dawnstar, Wildfire, Blok, and Green Lantern/Legionnaire Rond Vidar from rescuing the White Witch.
Mordru is then offered membership in the Legion, telling him it can only be temporary, which is the same case for the Fatal Five and the Justice League of Earth.
It has also been revealed that Saturn Queen reformed the group to bring anarchy back to the universe, starting with the destruction of the worlds that house the immortal beings that represent will (Oa), faith (the Rock of Eternity), and wisdom (Utopia, the World of the Wise, homeworld of supporting character Harmonia Li).
Additionally, Ron-Karr possesses shapeshifting abilities and Lightning Lord sports white hair and glowing blue eyes, both of which he acquired during the incident that gave him his powers.
First appearing in the episode "Lightning Storm", the group masquerades as a superhero team called the "Light Speed Vanguard" to outperform the Legion of Super-Heroes before their true intentions are exposed.
