Steel
Steel (John Henry Irons)
Voiced in Latin American Spanish by: Ramón Aguilera (Superman: The Animated Series), Alfonso Soto, Juan Guzmán (Justice League Unlimited)
Appearances: Superman: The Animated Series | Justice League Unlimited
The designer for an experimental suit of Powered Armor for the Metropolis SCU. After the pilot goes rogue, he redesigns and perfects the suit, taking it into battle himself in Superman's hour of need.
- Adaptational Early Appearance: In the comics, Steel debuted during the events of The Death of Superman. Here, he's around well before Doomsday appears and the events of "Hereafter".
- Arm Cannon: His forearm-mounted lasers.
- The Blacksmith: He hand-forged the plating of his armor himself.
- The Cameo: In Justice League vs. The Fatal Five, a statue of him can be seen in the Legion museum.
- Comic-Book Fantasy Casting:
- In "Tools of the Trade", Irons bears a strong resemblance to basketball star Shaquille O'Neal, probably because he debuted during Season 2, which first starting airing in 1997, the same year the Steel movie (where he was played by O'Neal) was released.
- According to the commentary for the Justice League Unlimited episode "The Return", Phil LaMarr's voice for Steel was supposed to emulate a young Morgan Freeman.
- Crapola Tech: Defied. After what happened to the prototype SCU armor, he's next seen double- and triple-checking the Steel armor before he puts it into action.
- Early-Bird Cameo: Irons initially turns up in the episode “Prototype” as the creator of the titular battle-suit, however he doesn’t adapt the armour for his own use and become Steel until “Heavy Metal”.
- Genius Bruiser: He fights using both his brawn and his brains.
- Meaningful Name: In addition to being an armored hero who goes by the name "Steel", his real name of John Henry Irons is appropriate since, like the folk hero John Henry, he stands for noble causes and uses a hammer as his weapon.
- Odd Friendship: With Supergirl.
- Powered Armor: Wears a suit of it that he made himself.
- Resign in Protest: In his premier he designed an experimental Powered Armor for Lex Corp., however he resigned to protest Luthor's decision to use it immediately instead of taking time to test out everything and correct certain potential flaws.
- Shout-Out: Like his name suggests, he's based on folk hero John Henry.
- What Happened to the Mouse?: He has an episode that introduces him, setting him up as Steel, then an episode where he becomes Steel...then vanishes until Justice League Unlimited. This is especially egregious since one episode later Darkseid invades. Really makes one wonder why he never bothered to help out. Well at least he was in time to help out on another one.

Green Lantern (Kyle Rayner)
Green Lantern (Kyle Rayner)
Voiced in Latin American Spanish by: Juan Guzmán (Superman: The Animated Series), Rolman Bastidas (Justice League Unlimited)
Appearances: Superman: The Animated Series | Justice League
A Daily Planet staff artist who is chosen to join the Green Lantern Corps, an intergalactic police force who use power rings to make green energy beams and constructs.
- Adaptation Dye-Job: In Superman: TAS, his hair is brown instead of black, which makes him look more like the Silver Age/Bronze Age Green Lantern Hal Jordan (who in the comics was dead at the time). By the time of Justice League Unlimited it's back to being black with no explanation.
- Adaptational Angst Downgrade: No girlfriend murdered by Major Force for this incarnation of Kyle.
- Adaptational Early Appearance: As far as Green Lanterns shown, he debuted in the DCAU before John Stewart (who was still a GL before Kyle in the DCAU) and Hal Jordan appear.
- Adaptation Origin Connection:
- Kyle becomes Clark's co-worker to explain his appearance in Metropolis.
- As a result of being a Composite Character with Hal Jordan, Kyle Rayner also becomes part of the Green Lantern Corps because Abin Sur passed his ring onto him before he died, which happened in the first place because Sinestro fatally attacked Abin Sur. In the comics, Sinestro had no involvement in the death of Abin Sur (and would eventually be established to have seen Abin Sur as a friend), while Kyle Rayner became a Green Lantern because Ganthet gave him a ring during a time where the Green Lantern Corps had disbanded.
- Badass Bystander: He stops a thief who stole Jimmy's camera (who looks exactly like Guy Gardner, another human Green Lantern).
- Badass Creed: You know the one. He doesn't know it at first, and the Guardians recite it along with him.
- Barrier Warrior: Sinestro tries to kill him once he gets the ring, so he has to quickly learn how to be one.
- The Cameo:
- He is among one of the attendees at Superman's funeral in "Hereafter", along with other members of the Green Lantern Corps.
- In Justice League vs. The Fatal Five, a statue of him can be seen in the Green Lantern display in the Legion museum.
- Composite Character: Kyle was the only Green Lantern active in the comics when Superman: TAS was made, so he was used instead of the other human Green Lanterns. But his origin, Arch-Enemy, costume, and even physical appearance are all basically Hal Jordan's, though he keeps his comic book counterpart's artist background. By Justice League Unlimited (where Hal Jordan eventually appeared himself), he looks closer to his comic book counterpart and his costume is completely redesigned.
- Costume Evolution: He gets the standard DCAU Green Lantern outfit in Superman: TAS while by JLU he's since switched to a Non-Uniform Uniform based on his then-current Jim Lee design. Vs. The Fatal Five shows that he eventually changes to his '90s throwback DC Rebirth outfit.
- A Day in the Limelight: His only episode in Superman: TAS, "In Brightest Day", was basically a Green Lantern story that featured Superman.
- Hard Light: The powers of a Green Lantern ring allow Kyle to create solid constructs of anything he visualizes in his thoughts made of green light.
- Heroic Willpower: The power behind his ring.
- How Do I Shot Web?: Having just gotten a Green Lantern Ring, Kyle struggles in how to use its power, eventually getting help from Superman from practicing the abilities and general uses of the ring.
- I Surrender, Suckers: He uses this tactic against Sinestro, where he pretends to give fighting him and hand him his own Green Lantern ring, only for said ring to be a decoy that blows up when Sinestro tries to take it.
- Only the Chosen May Wield: The ring itself chose him.
- Put on a Bus: By the time Justice League came out, John Stewart was the main Green Lantern with no sign of Kyle. It's later explained that Kyle was off training, with his mentor being John's ex Katma Tui. The Bus Came Back in JLU where he briefly has a speaking role alongside several other Green Lanterns.
- Remember the New Guy?: He is Jimmy's friend from the art department.
- Ring of Power: The Green Lantern ring, obviously.
- Sequential Artist: He's employed as a graphic artist, but wants to break into comics and has been submitting portfolios without success.
- Space Police: As a member of the Green Lanterns.
- Take Up My Sword: He replaces Abin Sur as the Green Lantern of Sector 2814, which Earth falls under.
Orion
Orion
Voiced in Latin American Spanish by: José Manuel Vieira (Superman: The Animated Series), Alex Orozco, Alfonso Soto (Justice League)
Appearances: Superman: The Animated Series | Justice League
Darkseid's younger son, who was raised on New Genesis.
- Archnemesis Dad: Of course like any other continuity and adaptation, Orion's greatest enemy is his own biological father, Darkseid. It's to the point where Orion refuses any ties with his father and is more than willing to oppose and even kill him should they ever meet.
- Be Careful What You Wish For: Before fighting Darkseid in Twilight, he asks "don't I get a hug". The fight ends with him getting a hug. It's not a loving and sentimental one, of course, but Darkseid squeezing him hardly enough that knocks him out.
- Curb Stomp Cushion: His last battle against Darkseid in Twilight. He manages to get some good hits and even impress his father for his efforts, but it's clear that the fight is in Darkseid's favor, who ends the fight by giving Orion a pretty tight bear hug that incapacitates him before Superman has his rematch against Darkseid.
- Dragon Ascendant: If one considers the Batman Beyond Unlimited/Justice League Beyond comics to be canon to the DCAU, he took up the mantle of ruler of Apokolips. He’s not happy about it, but he’s doing it in an attempt to maintain peace between the two New God factions.
- Fiery Redhead: He has red hair and he despises Darkseid with a passion.
- Flying Brick: The Astro-Harness covers the flight part.
- Foil: To both Kalibak (his biological brother) and Mister Miracle (his stepbrother).
- Like Kalibak, Orion is a hotheaded bruiser, but he's unquestionably a good guy and can be quite competent most of the time. Even when fighting Darkseid (the object of pure hatred for him), Orion keeps his wits about him rather than be a mindless brute like Kalibak. And of course, Kalibak deeply craves their father's approval, whereas Orion openly hates him and cares nothing for any Parental Favoritism shown his way.
- When they were both babies, Orion and Mister Miracle were exchanged as part of the peace deal. Orion grew up in the comfort of New Genesis, which guaranteed a strong moral core, but he still became a grump and generally not good with people. Mister Miracle, meanwhile, suffered repeated horrors in an Orphanage of Fear run by Granny Goodness before finally escaping, but he grew up into a far better adjusted adult, has no trouble interacting with others, and is generally well-liked by Earth's heroes.
- Happily Adopted: He loves his adopted father with as much intensity as he hates his biological one.
- Jerkass Has a Point: In the "Twilight" two-parter, he insists that there will never be real peace so long as Darkseid remains in power, which Highfather concedes is a valid point. Also, due to being more knowledgeable of Superman's history with Darkseid, he rebukes Wonder Woman's claim that Superman isn't out to start a war.
- Jerk with a Heart of Gold: Grumpy and abrasive as he may be, Orion's upbringing in New Genesis ensured that he turned out a noble, well-meaning, and supportive figure who is willing to help out other heroes and uphold the values and ethics of New Genesis. The "Jerk" part mainly comes from his nature as Darkseid's son, whom he despises as well as Apokoliptians generally turning out to be jerks at their best.
- Magical Computer: The Mother Box, which also soothes Orion's familial rage and opens up Boom Tubes.
- No Social Skills: Implied. In "Flash and Substance", upon greeting Flash with Batman after the former had just gotten done handling a criminal attack, he makes Captain Obvious comments about Flash's situation. In general, it seems mostly because he's a grump with a temper issue.
- Not So Above It All:
- After commenting on how boring and tedious it must be to attend the Flash’s museum opening, he receives a Death Glare from Batman. After a Beat, he decides he’ll tag along as long as it’s not black tie.
- In Flash's apartment, he accidentally bumps into Flash's talking standee, which he destroys after it startles him, something he sheepishly admits to.
- In the tie-in comic for Unlimited, after a long day’s mission with several other members of the League, he wonders out loud if anyone’s watched a romantic soap opera in the entertainment room that he’s been looking forward to watching.
- Patricide: He's willing to kill Darkseid, his father, if need be, mainly because he poses an unparalleled threat to New Genesis and the universe at large. All of their encounters with one another are just fights with Orion giving it his all in an attempt to end his father's tyranny once and for all.
- Perpetual Frowner: Even his helmet seems to be frowning.
- Pet the Dog: Following the death of Dan Turpin, he offered a devastated Superman his condolences.
- Physical God: He's a physical being, but is very formidable like the other New Gods.
- Red Is Heroic: He dresses mostly in a red suit and, despite his anger issues, he is indisputably a good guy.
- Red Is Violent: While a hero and someone who is willing to do the right thing, Orion is one of the more temperamental and hot-headed superheroes in the DCU, especially if his feud against Darkseid is bought up.
- Sky Surfing: With his Astro-Harness.
- Small Role, Big Impact: He has only a handful of speaking appearances in the shows, but he was the one who warned Superman of the oncoming Apokolips invasion and ensured that Earth would be granted Highfather's protection.
- Stellar Name: His name is derived from the constellation of the same name.
- Superhero Gods: He's a hero to New Genesis and the New God of War, having inherited Darkseid's great rage and temperament.
- Tempting Fate: After witnessing Batman agree to attend the opening of Flash's museum, he talks down to Batman for letting a "fool" like Flash "manipulate him" and declares he would never be caught at something as dull as a museum opening. Batman immediately gives him a Death Glare, silently telling him he just volunteered himself to join.Orion: It's not black tie, is it?
- Ugly Guy, Hot Wife: In the tie-in comics for Batman Beyond, it turns out that he married Bekka since then. While he looks like a brick, his wife is Ms. Fanservice.
- Unstoppable Rage: One that can only be held back by the Mother Box.
- What Happened to the Mouse?: Unlike many other heroes, he's not often seen in the background in Justice League Unlimited. Presumably, this is because he has business to attend to on New Genesis and/or is better suited for larger scale missions such as ones in space. In the finale when Darkseid is revived, though, he and the other New Gods from New Genesis are a no show, which is not explained other than the implication that they might have been busy dealing with Apokolips in the mean time.
- Worthy Opponent: He's seen as one for Darkseid, being the son who's turned out to be his most successful regarding reputation and strength, and he cites this as a major reason for why he intends to antagonize Orion and make his life hell. Of course, Orion doesn't reciprocate this.
- You're Not My Father: He hates Darkseid with every fiber of his being. It's not mutual.
Doctor Fate
Doctor Fate (Kent Nelson)
Click here to see him unmasked
Abilities: Expert sorceror; helmet provides immense magical abilities, exact limits unknown
Voiced by: George DelHoyo, Oded Fehr
Doctor Fate was mystical superhero who worked with Superman before. He's later become a member of the Justice League after the Thanagarian invasion who has magic powers.
- Above Good and Evil: For a short time, he held this opinion. He was roused from this Heroic BSoD when Superman - horribly outmatched by the Eldritch Abomination Karkull - went off to fight the demon alone.Dr. Fate: Until now, I thought it was just evil that never gave up.
- Achilles' Heel: Being designed to combat magical beings, Hawkgirl's Nth metal mace proved to an effective to his magic, as Doctor Fate found out the hard way.
- Adaptation Dye-Job: A blond in the comics, Kent Nelson is a brunet in the DCAU.
- The Cameo: In Justice League vs. The Fatal Five, a statue of him appears in the superhero museum in the 31st century.
- Character Development: Is introduced as a world weary man who's grown so tired of the seemingly endless struggle of evil that he gives up superheroics all together and devotes himself to mystical study, but has his faith restored after seeing Superman refusing to give up against an Eldritch Abomination. Gets taken further in Justice League Unlimited where he's the only one to not take a stand against AMAZO, believing that the android was still benevolent in nature.
- Cool Helmet: The signature Helm of Fate.
- Heroic Neutral: Was this in his debut episode, having given tired of the seemingly endless struggle against evil. But seeing Superman go up against an Eldritch Abomination he had no hope of winning inspires him back into action.
- The Mentor: Provides sanctuary, security, and occasional advice for people who are lost.Dr. Fate: I will help you [to discover your purpose.]
AMAZO: Help me? Why?
Dr. Fate: Because that is my purpose. - Odd Friendship: With Aquaman, AMAZO, Shayera, and even Solomon Grundy, who was buried on his property.
- Retired Badass: Gave up being a superhero after years of combating evil with seemingly no end, but is inspired by Superman's example to rejoin the fight.
- Remember the New Guy?: The Superman episode "The Hand of Fate" marked his debut — and also presented him as having worked with Superman before the events of the episode.
- There Are No Therapists: Averts this trope, as he counsels the League.
Aquaman
Aquaman (King Arthur)
Voiced by: Miguel Ferrer (Superman: The Animated Series) and Scott Rummell (Justice League/Justice League Unlimited)
Abilities: enhanced strength, super swimming, underwater breathing, marine telepathy
- "King of the Seas, remember?"
Aquaman is the King of the undersea realm of Atlantis and would later become a member of the Justice League.
- Action Dad: To his infant son in Justice League and eventually Aquagirl.
- Adaptational Badass: Somewhat; Aquaman is able to telepathically communicate and control all of underwater life in the comics. Here, he's even able to do this towards seagulls, something which has never been demonstrated before, presenting the possibility that Aquaman may be able to mentally interact with and control more than just sea animals in this continuity.
- Adaptational Jerkass: While still ostensibly a hero, this iteration of Aquaman is considerably more abrasive and rude than his comics counterpart.
- Animal Talk: He is able to communicate with marine life, anyway. Up to and including killer whales and the Kraken.
- Anti-Hero: Because of his insistence on his royal prerogatives and his narrow focus on what's best for Atlantis, he sometimes becomes an opponent of other League members. Despite a couple of friendships with other League members he sometimes seems to regard his work with the League as a series of Enemy Mine situations.
- An Arm and a Leg: He cuts his own hand off to save his son.
- Art Evolution: His character model from his previous appearance on STAS ("A Fish Story"), which was based on his traditional look, is discarded in favor of a new model inspired by his then-recent 1990s redesign. Ironically, Bruce Timm's admitted they had used the classic design on STAS because they'd hated Arthur's Nineties look. However, the look grew on them in the interim and they finally embraced it for this episode.
- Cain and Abel: He is the Abel to Orm's Cain, who wants to usurp Atlantis's throne from him and is more than willing to kill both him and his son to do the deed.
- The Cameo:
- In "Hereafter", he is seen as one of the guests at Superman's funerals. He's also shown to be Superman's replacement when Superman discovers the destroyed Watchtower in the future.
- In Justice League vs. The Fatal Five, a statue of him appears in the superhero museum in the 31st century.
- Chained to a Rock: He is chained to the bottom of an erupting undersea volcano along with his infant son by his usurping brother. He breaks one chain, then pulls a sharp implement off of his belt and hacks his own hand off at the wrist to save the both of them.
- Characterization Marches On: He was first introduced back in Superman: The Animated Series, where he was closer to his comic book counterpart via a green and orange costume and no beard. He also was slightly less bitter to humans in that while he still threatened to start war with them for polluting his oceans, he was at least nice toward Lois Lane. He already was just as powerful and badass, however.
- Combat Pragmatist : When Wonder Woman start to get the better of him on land, he quickly drag her underwater to drown her, exploiting his superior aquatic mobility and ability to live underwater to his advantage.
- Costume Evolution: When he appeared in Superman: TAS, he sported the classic look, complete with orange shirt, short hair, and a clean-shaven face. In Justice League, he sports a look based on when Peter David wrote him, including the Barbarian Longhair and beard, gold gauntlets, a medallion, and becoming a Walking Shirtless Scene.
- Curb-Stomp Battle : Is at the wrong end of one when he attempts to attack Superman in "The Terror Beyond". Superman merely sighs and lay him out cold in a single attack.
- Deadpan Snarker: Mostly deadpan and less-so snarker, but he has his moments.
- Decomposite Character: His role as a founding member of the League was given to Hawkgirl.
- Did You Just Flip Off Cthulhu?: In "Wake the Dead":Aquaman: Such scintillating repartee. I get better conversation from the android.
- Early-Bird Cameo: Just like the Flash, he appeared back in an episode of Superman: TAS before appearing in Justice League and Justice League Unlimited.
- Early Installment Character-Design Difference: His debut in the Superman: The Animated Series episode "A Fish Story" has him sporting his classic design of being clean-shaven with short hair and the orange and green costume, while Justice League instead followed his 1990s appearance where he had long hair and a beard in addition to going bare-chested.
- Expy: Unlike other versions of the character, this Aquaman is more of an ally of convenience than a genuine friend to the rest of Earth's heroes, treating humans with suspicion for the sake of protecting Atlantis and teaming up with more genuinely heroic figures like the Justice League against mutual threats. This ironically makes him more like Aquaman's Marvel Comics counterpart Namor the Sub-Mariner.
- Four-Temperament Ensemble:As always, Aquaman is very Choleric.
- The Good King: Aquaman isn't the nicest guy in the world, but Atlantis and its citizens are Aquaman's primary concern. He's even shown to be annoyed when not in his kingdom.
- Handicapped Badass: He handicapped himself by severing off his own hand in order to free himself from a deathtrap and save his son!
- Happily Married: He and his wife Mera are happy together.
- Heart Is an Awesome Power: Put it this way. His powers don't consist only of "talking to fish." He can control any and all marine life to awesome effect. This includes sea monsters, seagulls, etc.
- Hidden Depths: His take on faith.
- Hot-Blooded:Dr. Fate: Solomon Grundy's grave is empty.
Aquaman: Tell me where to find those responsible, then dig more graves. - Humans Are Bastards: He has this perspective towards Humanity given that their constant pollution has caused untold damage to Earth's oceans and it's inhabitants, and this is what brings him into conflict with Superman and Lex Luthor. He does mellow out during the events of Justice League.
- Jerk with a Heart of Gold: He's disrespectful and arrogant and has on more than one occasion considered war on the surface world, but he loves his country, his people and his son.
- Lord of the Ocean: Of course, he's the king of Atlantis, thus having absolute authority over the oceans and a formidably powerful figure in his own right.
- Nature Hero: Only when it comes to sea life, but he can control them, and his motivations are based on protecting the oceans from humans polluting them.
- Our Mermaids Are Different: He is an Atlantean, an human with the ability to breath underwater.
- Papa Wolf: You should never, ever threaten or harm his infant son. You won't live to regret it, even if you are his brother.
- Pay Evil unto Evil : Letting your brother fall to his death is normally a horrible move, but when Aquaman's case is someone who wants to kill him and his son for the sake of taking over Atlantis and be shameless about his deed, then you're instead anticipating Aquaman not caring when he just takes his trident and lets Orm fall to his doom.
- Pet the Dog: Helps defend Longshadow from Cadmus Agents.
- And his reaction to Solomon Grundy's resurrection.
- Plug 'n' Play Prosthetics: He is able to get a prosthetic hook attached within hours of losing his hand, with very little surgery involved. Granted, the cable launching function probably wasn't added until later, but Aquaman still used it as a weapon later that day.
- Poor Communication Kills: This version of Aquaman is incredibly rude and abrasive. The worst instance is in "The Terror Beyond", in which he didn't even bother to take 30 seconds to explain to the Justice League that the sea monster attacks were caused by an extradimensional being that he was trying to stop and he needed Solomon Grundy's assistance to do so, resulting in Superman, Wonder Woman, and Hawkgirl accidentally messin the ceremony up. The episode could have been wrapped up before the first commercial break if he'd just bothered to say anything beyond "this is Atlantian business."
- Proud Warrior Race Guy: The king of a proud, if xenophobic, people.
- Put on a Bus: As a result of DC's then policy of, "
Character Embargos", which prevented characters from appearing in one show if they already had a prominent role in another, Aquaman was barred from appearing in Justice League Unlimited after Season One, due to the unaired pilot of an Aquaman series that Warner was making at the time. - Refuse to Rescue the Disliked: Handed this to his Slime Ball sibling at the end of a preempted genocide. Though given that Orm had usurped his brother's throne through militia aid, sought to bring about a secretly calamitous cleansing of the surface world via polar meltdown he'd caused. Not to mention sought to consolidate his ill gotten power by killing off AC's only ''real'' successor to his kingdom...He pretty much had this coming.
- Save the Villain: Inverted hard; when finally at the mercy of his older brother, Orm begs to be saved as he is slipping to his death. But considering that Orm had tried to kill his brother and nephew in his selfish bid to take over Atlantis, Aquaman reaches out his hand... for his trident, allowing his brother to fall to his death.Aquaman: I believe this is mine.
- Shooting Superman: One of the Ultimen, Downpour, thought he could use his water-based powers to drown Aquaman. Guess how well that turned out.Aquaman: King of the seas, remember?
- Sixth Ranger: Aquaman gets a lot of recurring roles, and is the only member outside of the original seven to sit at the main table (when only part of the other seven are present). Before the League expanded, he was also the main person they would consider to fill in. The Bad Future Superman ends up in reveals that Aquaman did take Superman's place, before Vandal Savage's plan killed the League.
- Suicidal Overconfidence : Is quite confident that he can take down Superman in "The Terror Beyond", boasting that he'll explain the situation to Superman's "grieving friends". All it take to prove him wrong is one punch.
- Teeth-Clenched Teamwork: Every. Single. Time. As Hawkgirl puts it, he prioritizes Atlantis above all else and isn't the most dedicated to splitting his time.
- Although, he seems to have mellowed out by the time of Justice League: Unlimited.
- Took a Level in Kindness: Or cooperation at least. By the time of "Unlimited", he's far more willing to protect surface dwellers.
- In "Wake the Dead", Aquaman's antagonistic behavior during his game of chess with Shayera was a genuine attempt at helping her get back on her feet. This, coupled with his outrage upon hearing that Grundy's grave had been desecrated, indicates he has begun taking interest in things unrelated to the welfare of Atlantis. He seems to regard Doctor Fate as a friend as well, not just as a colleague.
- Walking Shirtless Scene: He does not wear a shirt during his appearances in Justice League and Justice League Unlimited.
- Would Hit a Girl : Has no issue with fighting Wonder Woman in "The Terror Beyond".
- You Don't Look Like You: His massive change in appearance and voice between STAS and Justice League is given no explanation.
The Legion of Super-Heroes
In General
The Legion of Super-Heroes
Appearances: Superman: The Animated Series | Justice League Unlimited
Inspired by the legendary Justice League, the Legion of Super-Heroes is an organization from the 30th century consisting of superpowered teenagers from all across the universe.
- Adaptation Relationship Overhaul: In the comics (barring some Cosmic Retcons that altered the Legion of Super-Heroes' history to downplay or outright discard their ties to Superman, usually in relation to the established continuity at the time choosing to eschew Superman's history as the original Superboy), the Legion were inspired to form because of the Man of Steel's exploits as Superboy and appreciated him enough to use time travel to recruit the young Superman-to-be into their team and allow him to participate on several adventures. In this continuity, while still inspired to form by a Superman who never was Superboy, they do not interact with Superman that much besides three of them visiting him as a teenager once in "New Kids in Town", with Supergirl being the one who joins them in the future instead (though she also became affiliated with the Legion in the comics after Superman reached adulthood).
- Brainwashed and Crazy: In "Far From Home", the Fatal Five manage to use a mind control device to capture Legionnaires and use them in their own personal army.
- The Cameo: Saturn Girl, Cosmic Boy, and Chameleon Boy are the only Legionnaires focused on in "New Kids In Town". In "Far From Home", it's just Brainiac 5 and Bouncing Boy. And, in Vs. The Fatal Five, it's Star Boy, Saturn Girl, and Brainiac 5. Everyone else is relegated to a brief silent appearance.

Brainiac 5
Appearances: Superman: The Animated Series (The Cameo only) | Justice League Unlimited | Justice League vs. The Fatal Five
A 12th-level intellect Coluan, descended from Brainiac, who had learned how to pass his code down biologically. Though he may share his ancestor's intellect, he has a sense of morality and refuses to follow his ancestors in the path of evil.
- Art Evolution: He is inexplicably depicted as bald in Justice League vs. the Fatal Five.
- Early Installment Character-Design Difference: In his cameo in "New Kids In Town", he had a mullet, his eyes were completely white, he had a different belt design bearing the Legion insignia on the buckle and he had an insignia on his chest resembling his ancestor's iconic diodes (which were not present on his forehead).
- Not So Stoic: For all his claims of being ruled by intellect, that's still a teenage boy in the suit.
- Oblivious to Love: He at first thought the symptoms of falling for Kara were because of guilt. Green Arrow soon sets the guy straight.
- Sins of the Father: He doesn't let it bother him too much, but he does feel guilty for what the other Brainiacs have done. And it gets him in trouble when Supergirl mistakes him for the original.
- White Sheep: Unlike the original Brainiac and presumably the other three Brainiac descendants, he's a good guy. He even calls himself the 'black sheep' of the Brainiac family.

- Nice Job Breaking It, Hero: Upon meeting John, he almost gives away that he'll be the father to Warhawk. John, who already knows due to the events of "The Once and Future Thing" (and since doesn't know if Warhawk will cease to exist now that he knows about him), tells him to shut up before he can finish that sentence.Bouncing Boy: You're the famous John Stewart! Father of--
John: You wanna shut up before you create a time paradox?
Bouncing Boy: Sorry. - What the Hell, Hero?: Gives one to Brainy for refusing to tell the three heroes that Supergirl may die since history says she never returned from the 31st century.

Here, while Dream Girl does make a cameo in Superman: The Animated Series, it's implied that his girlfriend in this continuity is Lightning Lass, whom he has some interaction with in the main continuity of the comics. Although, Lightning Lass (or rather Light Lass) and Star Boy are Bash Brothers in the Threeboot continuity of the Legion of Super-Heroes comics, which in that case makes this a Relationship Upgrade.
- Cassandra Truth: His ramblings about the Fatal Five and Limelight are initially dismissed as delusions.
- Commonality Connection: He and Jessica bond over being troubled heroes.
- Composite Character: He takes Saturn Girl's role from DC Rebirth as a time-displaced Legionnaire who winds up in Arkham Asylum (his comics counterpart willingly checked in to Sunshine Sanitarium).
- Dies Differently in Adaptation: In the comics, he was killed off during the 2011 Legion of Super-Heroes series as the result of an attack by the re-formed Fatal Five, though was later resurrected by the "Infinitus Saga" arc of Justice League United. Here, he dies by sacrificing himself to prevent Emerald Empress from destroying Earth's sun.
- Heroic Sacrifice: He sacrifices himself to restabilize the sun when the Emerald Eye destabilizes it.
- Meaningful Echo: Throughout the movie, he repeatedly states that he knows what he's doing because "I'm a superhero.". At the end, when he sacrifices himself to save the sun, he reassures Jessica that it'll be okay, because "I'm a superhero.".
- Meaningful Name: He lives up to his name by dropping into the center of the sun to use his gravity powers to hold it together, quite literally becoming a star.
- Mythology Gag:
- In the Threeboot continuity of the Legion of Super-Heroes comics, he and the Earth-Prime version of Lightning Lass, Light Lass, are partners. Here, they're implied to be a couple.
- His situation of being incarcerated at Arkham Asylum after going back in time is reminiscent of Saturn Girl's circumstances during DC's Rebirth era.
- Oh, Crap!: After he travels back to the present day, his medication for his schizophrenia breaks. This is a problem because his medication hasn't been invented yet at this time. As a result, he ends up getting checked in to a mental hospital after causing trouble and he struggles with his mania throughout the story.
- Official Couple: Heavily implied to be in one with Lightning Lass.
- One-Steve Limit: As a result of Adaptation Name Change, he shares his first name with the late Thomas Wayne. This was intentional by the writers, as it evoked a sense of familiarity to Batman (like Martha).
- Laser-Guided Amnesia: Due to a combination of crash-landing on Earth while trying to stop the Fatal Five's ship while time-travelling as well as the lack of medication for his manic disorder, he ends up having trouble remembering parts of his mission and that he had powers. It takes the events of the story to jog his memory, and even then, Miss Martian has to probe his mind to get more information.
- Power Incontinence: He has trouble controlling his powers due to his mania, but it's more because he's struggling to function with his mania more than his mania causing his powers to work improperly.
- Sanity Slippage: He undergoes this if he's off his medication, which is what happens in Vs. The Fatal Five when he gets stuck in the present day without it. It turns out that this is very bad, because if he's off his medication too long, then he risks becoming immune to it, thus being permanently stuck in his schizophrenic state. By the time of the main story, it's been ten months since he's been without his meds, but at least he's been in Arkham Asylum. Whether or not that actually helped or if the effect of his medication would've worn off is never revealed due to his death.
- Unperson: Initially, Batman and the authorities have trouble finding records of his existence, since he of course comes from the future and there obviously wouldn't be records of people who aren't born yet.
- You Are Not Alone: He and Jessica help each other cope with their own issues and end up growing close because of this.
