Cosmic Boy: Rokk Krinn was one of the Legion's founding trio. Upon teaming up with Garth Ranzz and Imra Ardeen to save one of the United Planets' highest ranking politicians- RJ Brande- the trio teamed together to begin the Legion of Super-Heroes with Brande's financial support. Cosmic Boy (or "Cos" to his teammates) has been the team's leader ever since, but had also proven himself as a true hero with his natural Braalian magnetic powers.

LIGHTNING LAD: Garth Ranzz never dreamed of the path his life would take him. One of the few Legionnaires not born with his powers, he, his twin sister Ayla and their older brother Mekt were caught in a freak accident granting each one of them powers. Soon afterwards, Garth helped two other youths save the life of a UP politician and went on the help form the Legion. Now, somewhat to Garth's dismay, he's become somewhat of an elder stateman in the Legion at a time when he only wants to be with his love Imra Ardeen- Saturn Girl- and occaisionaly go out and save the universe.

SATURN GIRL: Imra Adreen grew up on the moon of Saturn named Titan among a race of telepaths. Imra became one of the most skilled telepaths of her race, being able to expand her abilities above and beyond most others. One of the Legion's founders, she's also become of the greatest heroes in the United Planets, proving herself time and time again.

SUPERBOY: In his century, Conner Kent was the next in line to be the world's greatest hero. A clone, combining the DNA of Superman and Lex Luthor, Conner possesses a tactile telekinetic power, granting him flight, super strength, a degree of invulnerability, and the ability to create telekinetic fields. Recently he's begun to develop Kryptonian abilities much like Superman's, including heat and X-ray vision and greater strength and invulnerability. Finding himself trapped in the 31st century after a freak time travel accident that no one fully understands, Conner is trying to decide whether to try to make it home or stay with the Legion.

 
SHADOW LASS: Tasmia Mallor is another Legionnaire coming from a legacy of greatness. The "Shadow Champion" of her world, Tasmia seemed arrogant and headstrong at first, but has since proven to be a fierce warrior and loyal ally.

CHAMELEON: Reep Daggle is the son of a Durlan priest, and the Durlans' only true link to the United Planets. Although his involvement with the Legion has relaxed his own people somewhat, Reep doesn't care about how he affects his world. He's having a blast being a superhero.

SHRINKING VIOLET: Salu Digby is one of the Legion's newest members, and was accepted quickly. Born with the ability to shrink to sub-atomic size, Violet competed to be her world's Legionnaire, and proved herself when capturing one of the other competitors who resorted to murder to win. Since then, the shy young woman has adapted to her role in the Legion and gradually come out of her shell.

ULTRA BOY: Jo Nah is perhaps the most unusual Legionnaire. Gaining his powers after eating the flesh of a space whale while trapped in its stomach, Jo is one of the most powerful Legionnaires with a vast range of powers. Unfortunately for him, he can only access these powers one at a time. Arrogant and headstrong, the only other person he cares about beside himself is Tinya Wazzo, the Legion's Apparition.

APPARITION: Originally called Phantom Girl, Tinya Wazzo is one of the most unique Legionnaires. Although at first it was assumed her power was to phase through solid matter, Tinya discovered that she could actually exist simultaneously in two seperate realities, giving her the ability to move through solid matter and be undetected by any electronic device. Tinya is outgoing and fun, but secretly fears becoming trapped as a living ghost between realities.

PRINCESS PROJECTRA: Jeka Wynzorr is a member of the royal family of Orando. Seldom seen without her companion and bodyguard, Sensor, Jeka has the ability to create illusions and make them seem completely real. Initially feared by her teammates as being stuck up, Projectra has proved herself to be a loving and caring friend.

STAR BOY: Thom Kallor is part of a legacy in his homeworld of Xanthu. Using his mass altering powers, he became a champion of his people and joined the Legion alongside fellow Xanthusian Kid Quantum. He's become of Cosmic Boy's most trusted friends in that time, and consistently serves as a group leader for Legion missions.

TRIPLICATE GIRL: Somewhat of an enigma to her teammates, Luorno Durgo comes from a planet where she was the only survivor of an unknown cataclysmic event. Soon realising her ability to split into three beings, who could in turn split into three other beings and so on, she single handedly repopulated her homeworld of Cargg. Soon afterwards, the United Planets discovered Cargg and offered the race of women membership. They agreed on one condition- three of themself would join the Legion. Since then Luorno has become her own woman, and is now finding herself falling for her teammate Superboy.

VALOR: Once a legendary hero in the twentieth century, Lar Gand was trapped in the Phantom Zone for literal centuries to prevent his death by lead poisoning. Freed by the Legion he quickly joined the team, using his natural Daxamite abilities once again as Valor.

DAWNSTAR: Shikari Lonestar is unique among the Legionnaires. Coming from a distant galaxy, Shikari helped a group of Legionnaires return home after being deposited near her home. She and her race, the nomadic Kwai, have since allied themselves with the United Planets and the Legion, where Shikari puts her uncanny tracking skills to good use.
