Kid Flash And Artemis Fan Art
Later on New Earth, during the Final Crisis story line, Superman was called to the thirty-first century to assist the Legion of Super-Heroes in fending off Superboy-Prime, who was thrown to the future in the aftermath of the destruction of Earth-51 and the Sinestro Corps War. Prime, raging about his minor place in history as a Superman rival, released the entire Legion of Super-Villains from the prison planet Takron-Galtos and waged war on Earth and the Legion. In response to this, Brainiac 5 summoned the Legions of Three Worlds (alternate earths) to combat Prime's forces. Revealing that the Legion had captured "living lightning" in the Legion's last trip to present Earth in The Lightning Saga, Brainiac 5 had Legionnaire XS run on the cosmic treadmill while the three Lightning Lads activated the "lightning rod" to release the living lightning. Although he tried to stop them, Superboy-Prime was unable to stop the lightning from being unleashed. A fully formed alive-and-well Bart Allen, in his Kid Flash uniform, appeared before him.
