The age of the Legion of Super-Heroes began when Garth Ranzz, Rokk Krinn and Imra Ardeen rescued R.J. Brande from assassins on a spacecraft on its way to Earth. The first the kids saw on Earth was the Superman museum, where they were inspired to become heroes. They decided to track down the mastermind behind R.J. Brande's assassination, and it turned out that it was Roderick Doyle. This lead R.J. Brande to form the Legion of Super-Heroes.
The Legion's original members were Lightning Lad, Cosmic Boy, Saturn Girl, Phantom Girl, Triplicate Girl, Element Lad, Sun Boy, Tyroc and Bouncing Boy.
At some point, the whole Legion battled Fatal Five. When they escaped from their prison, some Legionnaires were unavailable, and Brainiac 5 thought they could recruit Superman. They only partially succeeded, as they didn't find Superman, but a young Clark Kent who still had trouble controlling his powers. Nevertheless, Superman showed to be the edge the Legion needed to defeat the Fatal Five. Brainiac 5 realised that it was in the 31st century that Superman would grow into the legend he would become in the 21st century.
Not long after Superman joined, the Legion found Brin Londo on the planet Rawl, and he joined with the name Timber Wolf. Over the time Superman first stayed in the 31st century, the Legion would often find themselves fighting "freak of the week"-type of villains, such as Alexis Luthor, the young magician Zyx and the Light-Speed Vanguard.
Some time later, a Controller released a Sun-Eater to destroy Earth and its sun. The whole Legion and the Legion's worst enemies had to become allies to build the weapon that could destroy the Sun-Eater. In the end, Ferro Lad sacrificed his life to save Earth. Superman, after he warned the Controller to ever return, returned to the 21st century, where he became Superman.
A few years after Superman had left (from the 31st century's point of view), Superman X, a clone of Superman from the 41st century, appeared and required the Legion to follow him. In the 41st century, most parts of the populated worlds had been destroyed by Imperiex, and Superman-X needed the Legion to stop him. The plan backfired however, when Imperiex stole Superman X's time travel device and went to the 31st century.
When the Legion followed, they were a week too late, and New Metropolis was almost devastated, however, not by Imperiex, but of the Legion of Super-Villains and of the Fatal Five. The Legion of Super-Villains and Fatal Five were, with few exceptions, quickly put back to their prison planet Takron-Galtos. Imperiex allied himself with the Dominators to destroy the Legion of Super-Heroes and the United Planets and have had many schemes to do so, but he has not yet succeeded, with them, except saving a boy named Abel from Terra-Man. That was the only time Imperiex and the Legion has been on the same side, as the Legion could not accept a young boy getting killed and as Imperiex knew Abel would in time be responsible for the creation of the technology that Imperiex was composed of.
A former opponent of the Legion, Zyx had his powers removed and appeared to the Legion and said that his homeworld Zarok had been conquered by the evil sorcerer Mordru. As they went to Zarok to investigate, Zyx explained that "only magic can defeat magic" and thus made Superman order him get his powers back. As the only way to restore legally removed magical Zarokian powers was to complete a series of Trials, Zyx and Superman-X went to do so while the others would distract Mordru. Zyx and Superman-X completed had to complete three trials, giving a swamp monster his egg, solving a riddle, and avoiding to become encased in crystal, before Zyx's powers returned. When they approached Mordru, the other Legionnaires were transformed into grotesque beasts, but as Superman-X had learned a magic counter-spell from Zyx, he could rescue them. With the combined powers of Zyx, Star Boy and the Council of Zarok, Mordru was encased in rocks, rendering him powerless.

- XS appears in the final two episodes Dark Victory part 1 and Dark Victory part 2 as a background character. Dawnstar and Invisible Kid also appeared in these final two episodes along with many other rarely seen Legion members; however, none of the new members shown in these episodes did anything to the plot of the story itself.
- In the first season, some Legionnaires were mentioned or shown as images before making an actual appearance. Fourteen members were shown during the season as already active: Blok, Bouncing Boy, Brainiac 5, Colossal Boy, Cosmic Boy, Dream Girl, Element Lad, Lightning Lad, Phantom Girl, Saturn Girl, Shrinking Violet, Sun Boy, Triplicate Girl, and Tyroc. Five more joined the Legion through the course of the series: Superman, Timber Wolf, Matter-Eater Lad, Star Boy, and Ferro Lad.
- The opening credits sequences used for first-season episodes included a glimpse of the Mission Monitor Board signs for many Legionnaires as well as shots of flying Legionnaires who would be seen in later episodes (though not all of those with Mission Monitor Board symbols appeared). At least four members of the Legion as seen in the comics appeared in some way on the show but had not joined by the end of the first season (Ultra Boy, Lightning Lass, Wildfire, and Polar Boy).
- In the second season, Karate Kid appeared in the opening credits with the other Legionnaires, though he did not appear until the fifth episode (in which Nemesis Kid also became a new member). Similar to Karate Kid, Sun Boy appeared in the second season opening titles and made semi-regular appearances but did not have a speaking line or have someone else refer to him by name. Ayla Ranzz, sister of Lightning Lad, finally made an appearance, but as a child without apparent super powers and not as the Light Lass of the comic books.
