Imra Ardeen aka Saturn Girl is one of the most talented telepaths among a race of powerful mentalists, Imra left her homeworld of Titan to join the Science Police as a teenager. However, during her flight to Earth, an assassination attempt was made on the life of fellow passenger and billionaire R.J. Brande. Using her powers of telepathy, Imra discovered the plot, and, with the help of two other teenagers on board, Lightning Lad and Cosmic Boy , caught the assassin and saved Brande's life. At Brande's urging, she adopted the persona of Saturn Girl, and joined Lightning Lad and Cosmic Boy in founding the Legion of Super-Heroes - an organization of teenage heroes formed to honor the legacy of Superboy. They traveled back to the 20th century and gave him a place on the team after he passed their tests. When Lex Luthor and the Legion of Super-Villains were about to kill Superman, Saturn Girl offered to die in his place, although a trick by Superman made Saturn Queen save her.
