People who have worked with or have been involved with the Legion at one point or another.

- Supergirl - When she arrived to the 31st century she joined them but later she left the Legion to rejoin her people. After helping to stop the war between Earth and New Krypton, she returned to the 21st Century.
Founding Legion members Rokk Krinn, Garth Ranzz and Imra Ardeen traveled through time back to the 21st century to stop the Persuader from killing Superman, aka Clark Kent. They found him to be at Clark's barn where he had just returned from seeing Jimmy off to Star City. After he had cut open his abdomen, Rokk took away his Atomic Axe using his ability of magnetism control and Imra distracted him using telepathy long enough for Garth to knock him out using his electricity before Rokk took away his stolen Legion ring sending him back to the 31st century.
Rokk, Garth and Imra then introduced themselves to Clark as the Legion of Super-Heroes. The three explained to Clark what he is truly destined to be - which is a model for all the galaxy for aliens to come to earth and live among humans. They realized that they had landed on the day Brainiac emerged in a human host and realized that they and Kal-El had to defeat Brainiac to kill the host after the Phantom Zone crystal (Red crystal) was destroyed.
They began tracking down Brainiac while at the same time pondering the 21st century commenting on the state of the planet and how it was being polluted. Garth then began to question Kal-El stating that they may have the wrong person as he was nothing like they had heard about in the future, however Rokk still believed in Kal-El.
They tracked Brainiac at the Daily Planet where he had just began to upload all of the human knowledge leaving the entire planet stood still before using an electro magnetic pulse to temporarily short circuit him. They plan to kill Brainiac by killing the host body, Chloe, before Kal-El stopped them and they took Brainiac back to the barn where they managed to extract him from Chloe with Imra connecting to Chloe telepathically, Rokk using his magnetic powers to extract Brainiac's microscopic parts while Garth used his powers to short-circuit him.
After defeating Brainiac by extracting it from Chloe, they intended on making a better use of it, in the form of Brainiac 5. Inspired by Clark's refusal to resort to murder despite their warnings, Rokk assured Clark that the Legion would make the preservation of life at all costs their first priority from then onwards. They later returned to their own time, after Rokk warned Clark about being careful in the days ahead, leaving him a Legion ring so that he could visit their time at some future date.
Returning from the future to the 21st century once again, Rokk goes to the Daily Planet rooftop to meet Clark and told him that by saving Chloe from Brainiac, he saved her connection to Doomsday and that Chloe is the reason that Doomsday cannot be defeated now since she made him immune to kryptonite when she tried to kill him with it and she stopped Clark from sending Doomsday to the Phantom Zone at the Fortress of Solitude with the Black crystal. Clark states that he wouldn't change his decision on saving Chloe no matter what happened and then Rokk tells Clark that tomorrow is the day he'll die if he goes up against Doomsday alone. He gives Clark another Legion ring since his old one got destroyed a while ago and suggests that Clark send Doomsday to the future to fight the Legion since nothing on the planet can stop him from killing him. He then returns to the future when Clark refuses to accept his help, stating that this is his problem, not the Legion's, and that he will embrace his destiny, even if it means that he'll have to die to do it.
Brainiac 5 revealed he is now a member of the Legion of Super-Heroes and that he is not the same Brainiac from the past. He also stated that he invented time-traveling. Brainiac 5 came back to show Clark's his past, present and future, and helping him letting go of his darkness which is his past.
Kara Kent slipped on a Legion ring after helping Clark all she could, and traveled through time, ready to accept her own destiny. 
During the 31st Century a war broke out between Earth and New Krypton. Garth was caught and taken prisoner aboard a spacecraft, he is rescued by fellow legionnaire Brainiac 5 who frees him from his restraint cuffs allowing him to access his electrical abilities and engaging his captors while also verbally bantering with Brainiac 5 as personal amusement. The ship transporting them was on a collusion crash heading towards the city of Metropolis, When Brainiac 5 notices a familiar emblem. Garth sees Clark now as Superman catch the ship and landing it safely to the ground. Afterwards he greets his old friend who asked them how he arrived their unfortunately their reunion is interrupted by a squad of EarthGov guards demanding their surrender.
With the aid from Skeets who causes a distracting for the group they move to the Legion safe house #47 where Clark now disguised in customary 31's attire explains that he was transported by the flight ring, which leaves Brainiac 5 and Garth puzzled as they have no knowledge to Protocol 6 and it wasn't enacted by any Legionnaire. Furthermore Garth persuades Brainiac 5 to reveal to Clark that his cousin, Kara, is held as a prisoner by EarthGov.
On New Krypton, Cosmic Boy and Saturn Girl disguised among the crowd try to locate Kirt Niedrigh's agents and stop them. Rokk manages to catch the agents and Imra disables the bomb but suddenly a group of Kryptonians, which protects New Krypton's citizents, leaded by Eradicator Beh-Osk appear and take into custody the two Legionnaires who are charged with terrorism. Rokk tries to explain that they mistake their actions and they were on New Krypton only to ensure peace but the Kryptonians do not believe them. Suddenly Superman and Supergirl appear on the scene defending Cosmic Boy and Saturn Girl.
In the Legion safe house, Booster Gold asks Brainiac 5 to help him with his broken flight ring but Brainiac 5 seems not to appreciate Booster as a person and doesn't believe that he had ever hard-earned something in his life. Booster actually confirms that by revealing that he stole his Legion ring from a museum in the 22nd century, where he was working, and that it was actually Superman's ring he stole. Brainiac 5 also confirms that except Kal-El's Legion ring Booster Gold has also stole his faithful intelligence, Skeets, and his wrist blasters. Booster Gold defends himself by saying that he had to "borrow" those things in order to become the hero he is now and asks Brainiac 5 to check the Legion's historical records so he can prove that he is a superhero too, like Superman. Brainiac 5 searches the records and finds no data on "Booster Gold". Booster tries to find an answer on why there is no record of him but Brainiac-5 says that he might never succeeded to become more than a "fake" hero. An insulted Booster gets out of the safe house but Brainiac 5 follows and apologizes to him, saying that he shouldn't had been so harsh on Booster considering his past crimes as Brainiac. Then he says to Booster that maybe he shouldn't think he needs to have his blasters or his flight ring to be a hero and he should try to make a difference without superpowers taking for example Clark, who had succeeded to be a great hero even when he had lost his powers. Booster then asks him again if he will ever fix his ring and Brainiac 5 gives him a look of disappointment.
High above the Earth, Saturn Girl, while holding Niedrigh's agents captive, contacts Brainiac 5 and informs him that Superman arranged their release but she is worried about the war procedures escalating. She also states that if they are not able to maintain peace they might have to contact every Legionnaire from all corners of space to hold the solar system together. Imra asks Brainiac 5 to activate "Legion Protocol Six".
On New Krypton, Supergirl asks Cosmic Boy why he is not with his friend Lighting Lad, with whom he used to be very close and he responds to her that he and Imra kind of avoiding him suggesting he is in a relationship with Saturn Girl. Rokk then asks Kara to tell him what she has learned while she was a spy for the Kryptonians and help the Legion stop the war. Superman arrives on the scene and says to Kara that she doesn't have to say anything, betraying the Kryptonians' trust because he already knows everything. He reveals to Supergirl and Cosmic Boy that the war is not about politics but actually for another, more religious reason.
As tension between Earth and New Krypton beings to reach it's perpetual climax, Cosmic boy assembles the Legion together and give them a heroic peep talk speech to inspire them to fight to end this conflict before more lives are lost in this senseless war.
When Kirt Niedrigh transports Doomsday to New Krypton to bring about it's destruction, Chancellor Lor launches a gravity bomb rocket to detonate in the heart of Metropolis causing the citizens to levitate uncontrollably. The Legion are joined by Superman and Supergirl in spac Brainiac 5 informs the cousins that the Kryptonians have launched an incoming gravity bomb at Earth in response to the attack by Doomsday on New Krypton. Clark seems surprised and Kara asks about Doomsday so Cosmic Boy explains to her that it was a monster that Clark defeated some years ago. Brainiac 5 says that it is possible Earthgov did not authorize the attack on New Krypton, or, if they did, maybe Kirt Niedrigh wasn't actually clear to his superiors about what he found beneath old Metropolis. Kara then asks from Clark to go to New Krypton because he has the experience to defeat the beast, due to his last encounter with Doomsday. Kara calls all the Legion members to follow her to Earth, except from Saturn Girl, who follows Clark to New Krypton.
With the gravity bomb activated on earth in Metropolis, Booster Gold along with Skeets commandeer a transporter ship and Booster decides that he'll use the ship to rescue the levitated citizens. He is joined by Kara and the entire Legion of Super-Heroes in the rescue efforts. As Kara beings to instruct the team on their assignments, Lighting Lad notices the approaching battalion of EarthGov ships. A voice from the intercom coming from the ship declares their presence is not their to fight but to aid the Legion, Both Lighting Lad and Brainiac 5 are uncertain in trusting Earth Gov. But Kara says that their been enough destruction to last a few lifetimes and decides to work alongside Earth Gov.
Meanwhile battle on New Krypton between Superman and Doomsday proves a great challenge for Superman and so he decides to bury him again only this time in the heart of the sun. Superman remains in telepathic communication with Saturn Girl he tells her certain instructions as he doesn't believe he'll make it out alive. He tells her to tell Lois, make sure that both Booster and Kara find a place in the 31st century.
Saturn Girl tells Superman it doesn't have to be this way, Using the full blast of his Heat vision Superman launches Doomsday into the gravitational pull of the sun with himself caught in it as well as they both plummet into the fiery tomb, Superman asked that the Legion would ensure that no one unearth this monster again.
Another Legionnaire interjects his opinion in telepathic communicating declaring that A lot of responsibility to rest upon one Legionnaire the voice is revealed to be Cosmic Boy who has come to Superman's rescue but not alone but with the rest of the Legionnaires creating a buddy system link chain to pull Superman out of the sun pull. As they declared that they wouldn't allow Superman to self-sacrifice his Destiny without a fight.
Together the Legion and the last two solo survivors of House of El fly as one unit of the sun proclaiming "Long Live The Legion" & "Long Live The House Of El".
Months later, Dominators are on a spacecraft at the edge of the source wall praying to the gods of order and chaos to forgive their transgressions of going against the master plan and searching for something more than dominion, and are fully ready to be punished resigning to their faith.
They are shocked when they are pulled up by a tractor beam, finding themselves to be rescued by the Legion members Brainiac 5, Chameleon Boy and Lightning Lad who are about to send them back into Dominator Space. Lighting Lad questions the Legion's rescue if they wanted to die. Brainiac 5 points out that Kal-El would have done the exact same thing. An alarm alerts them to the fact that the Source Wall beginning to crack and expel a strange form of energy that is all over the charts which Chameleon Boy refers to as looking to the readings say that it all amounts to "nothing". To avoid destruction the Legion, first transporting Dominator back to their territory, escape into a hyperspace jump back to Earth.
Horrifyingly the 'nothing' has followed them and is still gaining. It is an entropy wave that is now travelling in space and time erasing the past, present and future. The wave is reaching a focal point in the present day 21st century and so the Legion race to intercept, with Brainiac 5 creating the Legion Protocol Seven as a way to contact all Legionnaires.
During the battle, the Monitors suddenly change direction and race to reboot Smallville and if they succeed everything will be lost. Superboy has gathered all of the youngest of heroes and they prepare to stop the tide. Superman orders him to stand down but another team arrives to help, the Legion. With the Legion arrival as back up the Titans with Superman's blessing rush to stop the reboot in Smallville.
Three weeks after the battle with the Monitors, LexCorp holds a major press conference and Lex introduces the public to a new monument built on the former Watchtower site. In a massive turnout Lex publicly admits that if it weren't for the heroes of earth the universe would be lost. Then Superman makes a speech that is broadcast all over the world. The Legion also watches from the future as their existence is solidified.
Coming from the 31st century, technology is far more advanced than it is in the 21st century and so the Legion are able to time travel using Legion rings. A person can wear the ring and transport themselves anywhere in time and space as shown when the Persuader stole a Legion ring and went back in time to kill Kal-El so that he wouldn't be able to stop Brainiac from taking all knowledge off of Earth before Doomsday destroyed it.
In the Comics
The Legion's stories are set primarily in the 30th and 31st centuries (1000 years from the present), but have recurring connections via time travel with the present. Initially, the team was closely associated with the original Superboy and was first portrayed as a group of time travelers who frequently visited (or were visited by) the young hero destined to become Superman.
In later years the Legion's origin and back story were fleshed out, and the group replaced Superboy as the focus of their stories; eventually Superboy was removed altogether. The Legion has remained a somewhat popular DC franchise throughout its publishing history, appearing in regular features during most of this time. The founding members of the Legion were Lightning Lad, Saturn Girl and Cosmic Boy.In other media The Legion of Superheroes appear on Superman Animated Series in the episode New Kids in the Town, Justice League Unlimited in the episode Far from Home and had the Legion of Superheroes animated series that lasted for 2 seasons.
