The Legion of Super-Heroes
Superman/Clark Kent
Voiced by: Yuri Lowenthal Foreign VAs
Power set: Super-strength and durability, heat vision, freezing breath. Can fly even without his Legionnaire ring... but not very well.
- Adaptation Name Change: Due to legal issues with the Superboy name that occurred at the time from DC Comics getting sued by the estates of Jerry Siegel and Joe Shuster, he's simply referred to as Superman.
- Badass Cape: Would he really be Superman without the iconic red cape?
- Clark Kenting: Trope Namer. For this version of the story, both Superman and Clark are the "real person" wearing different clothes, neither being a disguise. The issue of a disguise persona is never dealt with in the show, which is justified because in the 31st century, people are only familiar to Superman as a legendary hero and there is no one to recognize him as Clark.
- Chest Insignia: Wouldn't be Superman without the S on his chest.
- Disney Death: Gets one in the season two finale "Dark Victory" when he supposedly dies after exposure to a Kryptonite crown, but later recovers after it turns out that he was merely put in a death-like state to recover from the Kryptonite poisoning.
- Extremity Extremist: Whenever he fights, Superman almost exclusively uses his fists.
- Fish out of Water: Both as a Kryptonian and as someone from the past.
- Flying Brick: He can fly and is very formidable.
- He Is All Grown Up: In season two, the Legion recruit an older Superman who is noticeably better-looking in addition to having a larger build.
- Innocent Blue Eyes: Of the "heroic and idealistic" variety.
- The Leader: He is not officially leader but the Legion defer to his judgment, if only out of respect to his heroic legacy.
- Messianic Archetype: Superman becomes this in "Dark Victory" and serves as much for the Legion as its resident Hope Bringer and has been compared to being a praised god by at least one villain. Becomes even more blatant to the point of being Jesus-like figure when he's betrayed by a close friend and seemingly dies from wearing a Kryptonite crown only to miraculously return alive and well.
- Naïve Newcomer: When he's first introduced but he gets to grips with it pretty quickly.
- Nice Guy: Hands down the nicest character in the show. He even attempts to convince Superman X about the values of friendship and teamwork.
- Out of Focus: In the second season, more attention is given to his successor Superman X. As a result, he appears much less frequently.
- Primary-Color Champion: Naturally. His costume has red, blue, and yellow and he's a very powerful hero.
- Rookie Red Ranger: He is recruited by the Legion to help them take down the Fatal Five when they overpowered them.
- Superpower Lottery: He wouldn't be Superman without this trope.
- Writing Around Trademarks: Is always called "young Superman" instead of Superboy; legal snarls meant that name couldn't be used (it was likely a change made late in production, as the early episodes' lip sync seems to match the name Superboy being spoken).
Lightning Lad
Voiced by: Andy Milder Foreign VAs
Power set: Here's a hint: he's not named Non-Electrocuting Lad.
- Adaptational Angst Downgrade: He takes losing his arm and having it replaced with a robotic prosthetic a lot better than his comic counterpart did.
- Adaptational Context Change: In the comics, he lost his arm and had it replaced with a prosthetic because it had to be amputated after getting poisoned by a giant Space Whale. In this continuity, his arm was blasted off by Imperiex.
- Artificial Limbs: From "Chained Lightning" onwards, he gets a robotic arm after his original one got blasted off by Imperiex.
- Berserk Button: The second season showed he couldn't stand working with or being around Dream Girl due to her having put his family through more turmoil when she lied about them finding Ayla. He gets over this when she gets framed and kidnapped by the Dark Circle, and personally rescues her in order to apologize.
- Butt-Monkey: He really hates Legion try-outs, usually because he winds up on the receiving end of someone's demonstration. In the spin-off comic of the cartoon, during Infectious Lass' try-out, he wound up with a form of lava acne and got stuck with Bouncing Boy's power (and physique). What sucked worse is that, the virus that switched his power with BB's lasts longer on people with greater mass.
- Cynicism Catalyst: The death of his sister Ayla during the attack that granted him and his older brother Mekt their powers pushes them into their guilt-ridden Cain and Abel complex, along with Garth's cynical attitude and Mekt's path into villainy. Subverted in that she didn't die at all and was eventually restored to a physical form.
- Everyone Has Standards: Garth is known to be brash and short-tempered, but Cosmic Boy's dismissive and sometimes callous attitude rubs him the wrong way. Especially in regards to how Rokk apparently never visited Saturn Girl while she was recovering from Esper's attack in the second season.
- Fiery Redhead: He has red hair and is often short-tempered.
- Fire-Forged Friends: His animosity towards Dream Girl vanished after she got kidnapped by the Dark Circle and they become friends, to the point the tie-in comic showed he was up for the idea of dating her (much to Saturn Girl's annoyance).
- Good Parents: He was seen embracing them after the storm that devastated Winath, happily embracing their children in the photo before he and his siblings got their abilities and him bringing Ayla home to see their parents.
- Good Scars, Evil Scars: Lightning Lad has a lightning bolt-shaped scar over one of his eyes.
- Graceful Loser: Subverted in Champions. He's clearly not happy at having lost to his brother due to having stopped to help another competitor who was in danger but handles it better than you'd expect. If anything, he definitely had a reason to sulk considering Mekt cheated.
- He's All Grown Up: Has a shirtless scene in Chained Lightning to demonstrate this.
- Hidden Depths: He's shown to be the most complicated of the Legion's founders and has the most depth compared to both Cosmic Boy and Saturn Girl, despite coming across as an arrogant hothead.
- He's suffered the most in regards to physical and emotional trauma growing up, from losing his twin sister and his older brother running away, to losing his left arm thanks to Imperiex. Coming off the loss of his arm, there's the fact he couldn't turn to Cosmic Boy or Saturn Girl for help since Cosmic Boy was off doing stuff as Legion leader and Saturn Girl was still in her healing trance, meaning he had to process that trauma without his closest friends by his side.
- His greatest fear in "Fear Factory" is shown to be complex emotions regarding his PTSD from the lightning beasts attacking him, Ayla and Mekt when they were children. Over a decade after it happened he was still having nightmares about Ayla's supposed demise.
- He's genuinely overjoyed at being reunited with his sister even though he's now years older, and they're both happy that Mekt reformed.
- He visited both Saturn Girl and Matter-Eater Lad while they were hospitalized in the second season, even while Imra was still in her healing trance. Imra even thanked Garth for taking care of her and keeping her company while she recovered.
- His animosity with Dream Girl over her past as the con artist "Madame Mysterious" was due to his parents having been scammed by her into thinking they'd find Ayla on a certain planet, which he claims devastated them when it never happened. While she's genuinely remorseful and he does patch things up with her, it's clear Garth's dislike came out of anger towards how she hurt his parents.
- Jerkass Has a Point: Played with. He's initially not fond of Dream Girl, and while at first his behavior seems like he's disproportionately holding her past as "Madame Mysterious" over her head we later find out his parents were scammed by her into thinking they'd find his sister in a scenario that never happened. And Dream Girl's later ashamed admittance that "it was sometimes easier to tell people what they wanted to hear" rings somewhat hollow because it underscores just how badly she hurt Garth's family when it would've been better had she just been honest with them. Though he does eventually forgive her for real when she's framed and kidnapped by the Dark Circle, to the point of personally rescuing her.
- Jerk with a Heart of Gold: He's arrogant and raucous, but he still fights for what is right.
- The Lancer: He becomes the second-in-command when Superman joins the team.
- Locked into Strangeness: His scar and eyes are a result of the Lightning Beast shocking him and his siblings that granted them their abilities.
- Major Injury Under Reaction: When he comes to and realizes his arm has been replaced with a prosthetic, his response is to say "Sweet" in an impressed tone of voice. Somewhat justified due to being informed that his new arm is equipped with powerful weaponry.
- Odd Friendship: With Matter-Eater Lad. The two were competitors together in Champions, and when Tenzil tries out for the Legion Garth's happy to see him and compliments him on his codename. We don't see the two interact that much, but come season two Garth's taken an active interest in making sure Tenzil heals after he takes a bite out of the Emerald Eye and visited him reguarly at the hospital alongside Saturn Girl.
- Real Men Wear Pink: Has surprisingly good bedside manner, as demonstrated by him trying to get Matter-Eater Lad to eat so he would recover quickly in the hospital. And then of course there's the fact that he loves his little, formerly twin sister dearly.
- Shock and Awe: His power is firing bolts of electricity.
- Ship Tease: Gets a lot of this with Saturn Girl, especially in the comics.
- Teeth-Clenched Teamwork: With Dream Girl in season two. His reason for doing so is that she used to be a con artist fortune teller called Madame Mysterious, but the real reason behind his dislike is she told his parents that they would find his sister Ayla on another planet and it never happened, which devastated the two. Though their relationship has softened by the end of Nura's spotlight episode.
- Took a Level in Kindness: He develops a very noticeable soft side in the second season. He's overjoyed to be reunited with his sister Ayla, and is happy that her return prompts Mekt to do a Heel–Face Turn. He also spends time visiting Saturn Girl and Matter-Eater Lad at the hospital while they recover, even passing on an awards ceremony to see the two. Garth even prompts Tenzil to eat more so he can recover quicker.
- Trauma Button: In "Fear Factory" his greatest fear is shown to be a clown doll called "Captain Howdy." Ridiculous at first glance, until Lightning Lad starts exclaiming "it only came out during thunderstorms" followed by a lightning beast emerging from the doll's mouth. With "Chain Lightning" revealing how Garth thought his twin sister was killed by a lightning beast, to the point he was still having nightmares about it, it becomes clear the clown doll was linked to his childhood PTSD.
- Tritagonist: He, along with Superman and Brainiac 5, are the closest things the cartoon had to main characters. In both seasons Lightning Lad had a great deal of character development and his own arc spread throughout multiple episodes deceptively hidden by the fact they didn't happen back to back. This is especially prominent compared to Saturn Girl who was Out of Focus in the second season and Cosmic Boy who didn't appear until the first season was nearly over.
Saturn Girl
Voiced by: Kari Wahlgren Foreign VAs
Power set: ESP and telepathy; projection of psychic illusions.
- Action Girl: She gets to join in the action frequently as one of the team's core members.
- Big Ol' Eyebrows: Her eyebrows are very prominent.
- Humanoid Alien: She's clearly not quite human, but very similar.
- The Heart: She's quite good at handling people. She did show a great deal of compassion for Timber Wolf before his true identity was revealed.
- Master of Illusion: She can use her telepathic abilities to trick people into seeing things that aren't really there.
- Mind-Control Eyes: Her eyes glow whenever she uses her psychic abilities.
- Mind over Manners: Lightning Lad once stated that she could read a persons thoughts even when she's unconscious. Since she's unconscious she can't stop herself, and will sometimes pick up on things she shouldn't.
- Out of Focus: She appeared less frequently during season two.
- Psychic Powers: Her main power is telepathy.
- Technicolor Eyes: She has violet eyes.
- Telepathic Spacemen: She is an alien and she has mental powers.
Brainiac 5
Voiced by: Adam Wylie Foreign VAs
Power set: Super-intelligence along with extensible limbs, reprogramming computers by touch, limited shape-shifting, and the Required Secondary Powers of a synthetic being.
- Adaptational Badass: In the comics, Brainiac 5 was formidable but he was already in his humanoid state and had no special skills besides his intellect. In the show, he's literally a battle-ready Do-Anything Robot complete with his super-intellgence who can take down the entire Legion, his home planet, and overcome the galaxy itself if he wanted to.
- Adorably Precocious Child: An adolescent who acts more mature than his teammates.
- Ambiguously Gay: His devotion to Superman sometimes comes off as more than just mere admiration.
- Brainwashed and Crazy: He acts against the Legion when Brainiac 1.0 takes control of him.
- Do-Anything Robot: He has a robotic body and he can transform his arms into any tool or weapon needed.
- Gadgeteer Genius: He's the defacto builder and engineer of the team, having built everything from their flight rings, their ships, and basically anything else they need.
- Genius Bruiser The genius part is blatantly obvious, the bruiser part comes in when he takes on a twelve-foot 'battle form'.
- I Did What I Had to Do: Less of a single occurrence and more of a defining motivational trait - Brainiac 5 often makes the tough, pragmatic and/or rational decisions, and willing to pay high costs (including sacrificing himself, or on rare occasions others) if he feels it needs to be done or the alternative is something much worse. This extends to everything from saving the day to preserving the timeline, and becomes particularly obvious in "Message In A Bottle" and other episodes dealing with Brainy ensuring that Superman doesn't learn too much about his past. This is pointed out by the original Brainiac, who uses this part of Brainiac 5 to create a connection between himself and Brainy. As his resistance breaks down, Brainy slowly starts to believe that his tendency for this makes him not so different than Brainiac 1... and that's all 1.0 needed.
- In-Series Nickname: His teammates frequently address him as "Brainy".
- Insufferable Genius: He comes off as this to the rest of the Legion at times when his Techno Babble becomes tiresome
- Legacy Character: He is a descendant of the original Brainiac, one of Superman's enemies.
- Locked into Strangeness: In an interesting reversal he was an android at the start of the series but at the end he became human (albeit with green skin and white circles on his forehead) after defeating Brainiac in his mind.
- Losing Your Head: For most of the episode "Brain Drain", a teleportation mishap results in his head being separated from his body.
- Mechanical Lifeform: He is an android, but also acts human.
- Out-of-Character Moment: His entire character after the first few minutes of "Brain Drain" due to a malfunction. Hilarity Ensues.
- Pragmatic Hero: "Phantoms" reveals he has a piece of kryptonite around, which would be sensible in case Superman went rogue. He also justifies erasing Superman's memory at the end of "Message in a Bottle" because he doesn't want to risk history being changed by Superman's knowledge of the future. This becomes a deconstruction of the pragmatic hero idea when his pragmatism puts him at heavy odds with his team and eventually makes him a slave to Brainiac 1.0 when his pragmatic behavior is pushed to its extreme.
- Robot Buddy: He is an android and gets along well with the other Legionnaires.
- The Smart Guy: He is the brains of the team.
- The Spock: Focuses on logic to the point that he stubbornly tries to deny the existence of magic even while Zyx uses his reality-altering powers on him.
- Spock Speak: Part of his intellectual personality is using technical terms while speaking in a serious tone of voice.
- Technicolor Eyes: His eyes are purple.
- Telescoping Robot: He can extend his neck and limbs.
- Well-Intentioned Extremist: Comes off as this when he is controlled by Brainiac 1.0 in "Dark Victory", claiming that with his order he can end suffering and prevent everything from falling into chaos.
Bouncing Boy
Voiced by: Michael Cornacchia Foreign VAs
Power set: Self-inflation and bouncing ability. Don't laugh too hard: he's exceptionally durable and an excellent tactician.
- Acrofatic: He's quite versatile for someone of his girth.
- Ascended Fanboy: Was a fan of the LOSH and tried for years to be a member. He eventually succeeded and became their leader for some time.
- Big Eater: The first episode alone makes it clear that he loves food. For instance, he's quite thrilled to discover hot dogs and cotton candy.
- Big Fun: He's overweight and all about having a good time. He's also endearing to new candidates being one himself who was overlooked multiple times before being accepted and tries his best to help anyone's mood.
- The Big Guy: He quite often uses his bouncing ability to break through barriers and pummel his enemies.
- The Chains of Commanding: Feels them when he gets put in charge of the Legion.
- Dark Horse Victory: Wins the Legion Leader Election in "Chain Lightning" despite Cosmic Boy and Lightning Lad being the frontrunners due to leading the Legion in saving all of Winath.
- Genre Savvy: Comes with being an ancient horror movie fanboy. He's also quite savvy of villain schemes due to being a movie buff.
- Heart Is an Awesome Power: He was let in eventually and is a useful member of the team by the time of the show.
- Plucky Comic Relief: He serves as the jokester of the group.
- Hyper-Destructive Bouncing Ball: He IS a bouncing ball that can cause great damage!
- Mission Control: When he is piloting and the others are in action. Exceptional work at this briefly gets him elected leader of the entire Legion.
- Ship Tease: Hints are dropped of something going on between him and Triplicate Girl.
- What Kind of Lame Power Is Heart, Anyway?: He was rejected from the Legion four times before finally being let in.
Phantom Girl
Voiced by: Heather Hogan-Watson Foreign VAs
Power set: Well-controlled insubstantiality: the ability to induce insubstantiality in other people or matter.
- Action Girl: One of the team's core members, she's often involved in the action.
- Eerie Pale-Skinned Brunette: She's much paler than the other girls in the show, and the design of her costume and face suggest a skull.
- Family Eye Resemblance: Has gray eyes just like her mother's.
- The Heart: Served this to Lightning Lad and Timber Wolf when both were dangerously close to becoming murderers.
- Intangibility: She has the power to phase through solid material as if she were a ghost.
- Out of Focus: Like Saturn Girl, Phantom Girl received less screentime in season 2 because of
Executive Meddling. - Screw the Rules, I'm Doing What's Right!: When she aids Timber Wolf despite the Legion's laws.
- Ship Tease: With Timber Wolf though she also has some romantic leanings for Ultra Boy.
- This Looks Like a Job for Aquaman: She's the most powerful Legionnaire in the Phantom Zone.
- Well, Excuse Me, Princess!: She can be pretty petulant at times especially when others are simply trying to help her out of kindness which she mistakes for condescending pity or sexism, notably towards Timber Wolf.
Timber Wolf
Voiced by: Shawn Harrison Foreign VAs
Power set: Strength, speed, and durability. Becomes considerably more dangerous, in every sense, when enraged.
- Brainwashed and Crazy: Daddy dearest used his nanites to turn him into this, it was seeing Phantom Girl's unconscious body that snapped him out of it.
- Calling the Old Man Out: Gives his pop quite the tongue-lashing for treating him as an experiment rather than his own child.
- Clear My Name: Was accused of killing his father and the Legion and Science Police hunt him down, as it turns out he was the real killer but the victim was his father's clone.
- Dangerous Forbidden Technique: Timberwolf regards his alternate form as extremely hazardous, partly because he has no control over shifting back.
- Guinea Pig Family: His wolf-like appearance is the result of his dad experimenting on him.
- Hidden Depths: He likes to cook. He particularly likes to bake cookies for his teammates.
- Lightning Bruiser: In Season Two, he's built like a tank, and although he's not as fast as speedsters or Superman, he still moves in a blur.
- Locked into Strangeness: In pictures it was shown he was a normal human boy until his father tampered with his DNA too much. After he was restored from his werewolf-like state he maintained the cat-like eyes, fur, claws, fangs and pointy ears from his feral form.
- Misunderstood Loner with a Heart of Gold: Was originally treated like a mindless animal (his father tricking the Legion so they can capture him) until Saturn Girl uncovered the truth, helped restore his humanity, and his sense of goodness.
- Our Werewolves Are Different: He became a wolf-like humanoid because his father experimented on him.
- Resist the Beast: In "Cry Wolf" he does experience this trope and trying hard not to revert into his bestial form in one such instance he was struggling with his monster form when Phantom Girl tries to coax him back to normal... until the Science Police came in and attacked him causing him to run and fly to Rawl so that he wouldn't be a danger to anyone else.
- Slasher Smile: Does this in "Cry Wolf" where the nanites have taken control over him
- Sixth Ranger: Joins the team by the end of his first appearance.
- The Stoic: He often has a serious demeanor.
- Vomit Discretion Shot: In the spin-off comic of the cartoon, Timber Wolf gets motion sickness on the trip back from Rawl; fortunately Superman manages to get him off the ship before he could show the Legion what he had for lunch.
- Wolf Man: He's a humanoid wolf.
- You Wouldn't Like Me When I'm Angry!: When angered, he becomes larger, more monstrous, and more aggressive.
Triplicate Girl
Voiced by: Kari Wahlgren Foreign VAs
Power set: Self-duplication, some martial arts skills.
- Action Girl: She often appears on the scene to lend a hand during the team's battles.
- Despair Event Horizon: When one of the duplicates is seemingly killed.
- Genki Girl: The most peppy and excitable of the female Legion members.
- Literal Split Personality: Each of the three duplicates she splits into are semi-individuals with slight differences in personality to the point that they're both one person and yet also like very close sisters.
- Magic Skirt: In spite of how short her skirt is, it never changes position.
- Me's a Crowd: When under the influence of magic, her duplication power spirals out of control creating dozen of copies that continue to endlessly fill the Legion's spacecraft.
- Status Quo Is God: After being minus a third of her for most of the second season, the season finale (and ultimately the series finale due to cancellation) ends with her reuniting with her restored third self.
Chameleon Boy
Voiced by: Alexander Polinsky Foreign VAs
Power set: Shapeshifting.
- Deadpan Snarker: He makes a few sardonic quips, most notably in regards to Karate Kid's optimism.
- Hero-Worshipper: In "Who Am I", it's shown that he idolized Superman for years before he even joined the Legion.
- In-Series Nickname: He is often addressed as Cham.
- Keet: He is very energetic.
- Kid-Appeal Character: He's mainly introduced in the second season because the other Legionnaires have become serious and more mature after the Time Skip.
- Magic Pants: His clothes disappear whenever he shapeshifts, but he somehow still has his clothes whenever he returns to his normal form.
- Memory Gambit: Was a part of this for Brainiac 5's plan of infiltrating Imperiex's forces by impersonating Persuader in "Who Am I?". In addition to assuming Persuader's form, Chameleon Boy had his mind altered so that he believed he really was Persuader. By the end of the episode, he's returned to normal and has his real memories restored.
- Plucky Comic Relief: Good-natured and fond of puns.
- Voluntary Shapeshifting: His power is changing himself into any living thing.
Ferro Lad
Voiced by: Dave Wittenberg Foreign VAs
Power set: Ability to turn his body into living iron that increases his strength and endurance.
- Extra-ore-dinary: His superpower turns him into living iron.
- Facial Horror: He says to Lightning Lad he's doing everyone a favor by wearing his mask.
- Heroic Sacrifice: Uses himself as a conductor to trigger the bomb to destroy the Sun-Eater, saving Earth and the Legion at the cost of his life.
- Sacrificial Lion: As a nod to the comics, he sacrifices his life to save the legion in the Season One finale.
- Super-Strength: He's incredibly strong in iron form.
- Super-Toughness: He can withstand a lot of damage in iron form.
Superman X/Kell-El
Voiced by: Yuri Lowenthal Foreign VAs
Power set: Super-strength, invulnerability, heat vision, cold breath, flight.
- Anti-Hero Substitute: He's more antisocial, ruthless, and goal-oriented than the original Superman and doesn't have any qualms with using excessive force. He serves as a deconstruction when his "win at all costs" brutal approach earns him the distaste of his team and he eventually changes his ways.
- Alternative-Self Name-Change: To differentiate him from Superman, everybody chooses to refer to him as Kell-El.
- Blade Below the Shoulder: Can form energy from the back of his hands.
- Clone Angst: He is cloned from Superman's DNA and is frustrated that the Legion find the original Superman superior to him.
- Composite Character: Of Kon-El (clone of Superman) and Superman from the 853rd century (a successor of the Man of Steel from even further in the future). His affiliation with the Legion and having Superman's powers but an immunity to Kryptonite also makes him similar to Mon-El/Lar Gand.
- Genetic Engineering Is the New Nuke: Created specifically to turn the tide against Imperiex in the 41st Century, he's the result of Superman's DNA being mixed with Kryptonite and as such is immune to the green rocks effects. It also has the added side effect of granting him different powers.
- Gemstone Assault: Thanks to the Kryptonite into his DNA he can summon crystal structures to surround and bind his enemies.
- Good Is Not Nice: His aim is to destroy Imperiex and to save trillions of lives from destruction, but he's an abrasive, compassion-deprived, ruthless survivalist who doesn't care much about individual lives to meet his goals. His less than friendly demeanor has even led to the original Superman implicitly comparing him to Batman.
- Laser-Guided Tyke-Bomb: He was created to stop Imperiex.
- The Only One Allowed to Defeat You: He doesn't want anyone else to defeat Imperiex.
- One Hero, Hold the Weaksauce: Kryptonite is mixed into his DNA; as a result, he's immune to it.
- Superpower Lottery: In addition to the standard Kryptonian powers, he is immune to Kryptonite.
- Suspiciously Similar Substitute: Since the rights to Superboy were being disputed at the time of the show, they couldn't use the Conner Kent/Kon-El version of the character. Superman X was created in his stead.
- Red Oni, Blue Oni: The Red to Superman's Blue.
Cosmic Boy
Voiced by: Wil Wheaton Foreign VAs
Power set: Metal control.
- The Captain: He is the de facto leader of the Legion of Super Heroes.
- Demoted to Extra: In the comics he's one of the most prominent members of the legion and is generally part of a Two Guys and a Girl trio with Lightning Lad and Saturn Girl. Here his role is much less prominent.
- Extra Oredinary: He can manipulate metal.
- The Friend Nobody Likes: His pompous attitude adjustment in the second season made you wonder how many of his teammates actually liked him.
- Good Is Not Nice: While he's the leader of the Legion of Super Heroes, he's kind of a dick.
- Jerkass: He is very rude towards the inexperienced Chameleon Boy and also turns away Karate Kid just for lacking powers.
- Took a Level in Jerkass: By the second season, he developed a rather cold and judgmental attitude as Legion leader to the point Chameleon Boy and Lightning Lad frequently felt annoyed by his behavior.
- Unresolved Sexual Tension: With Saturn Girl. In "Chain of Command", he tried to protect her from harm's way, but she told him he can take care of herself and leaves before he can apologize. In the episode "In the Beginning", he's upset with Saturn Girl for always taking Lightning Lad's side.
- What the Hell, Hero?: Lightning Lad calls him out for not even having the time to visit Saturn Girl while she's in a temporary coma.
Shrinking Violet
Voiced by: Kari Wahlgren Foreign VAs
Power set: Shrinking.
- Ascended Extra: She only had one speaking part in the first season finale, but pretty much became part of the main cast in the second season.
- Deadpan Snarker: She has a snarky sense of humor but it's not as dry as Brainy's, which is one reason why the two get along.
- Genius Bruiser: This type tends to be.
- The Napoleon: She's very sensitive about her height.
- Nice Girl: She is very sweet and supportive of her teammates.
- Ship Tease: She seems to spend a lot of time with Brainiac 5.
- Shrinking Violet: Averted in spite of her name, visually she gets smaller and wears dark purple but she does not have this personality at all.
- Tomboyish Voice: She has quite a raspy voice.
Villains
The Fatal Five
- Adaptational Early Appearance: In both the comics and the first season finale, the Five help the Legion to fight the Sun-Eater. Only in the comics, it was a case of "Nice Job Breaking It, Hero" as it was how the group first formed, whereas the group was already active well before that point in the show.
- Adaptational Hairstyle Change: Tharok has a full head of hair on his organic half, when his comic incarnation was bald on both sides of his body.
- The Brute: Validus is the muscle of the group. He later becomes The Dragon to Imperiex, yet is The Brute while in the Fatal Five.
- Evil Genius: Tharok serves as the smartest of the team and is even said to be as smart as Brainiac 5.
Light Speed Vanguard/Legion of Super-Villains
- Fun with Acronyms: Although the initials don't spell out a word, they're the same in the old and later name of the team: LSV.
- Heel–Face Turn: Although they weren't seen after their "turns", Lightning Lord and Ron-Karr.
- Jerk Jock: Mekt "Lightning Lord" Ranzz in "Champions", before joining the LSV.
- Jumping Off the Slippery Slope: The Light Speed Vanguard at first seem Cooler And More Effective Heroes, then Kinda Selfish Mercenary Heroes, then Ruthless Protection Racket.
- Locked into Strangeness: Like his brother the Lightning Beasts shocked him and his eyes and hair changed.
- Morality Pet: For Mekt in "Chained Lightning". Many years ago, dead little sister. Then, Not Quite Dead (which puts Even Evil Has Loved Ones back into play), followed by Unexplained Recovery. As he directly contributes to Ayla's restoration, he surrenders to prison without a fight.
- Psycho Rangers: Each member is a counterpart for a Legionnaire.
- Esper is a telepath like Saturn Girl
- Hunter and Timber Wolf are both bestial fighters who have experience dealing with dangerous creatures.
- Lightning Lord and Lightning Lad both have the ability to fire bolts of electricity.
- Ron-Karr and Wave — Bouncing Boy and Triplicate Girl (as the team's ship crew)
- Tyr claims to have powers matching Superman's and is apparently strong enough to trade blows with him.
- Tomato in the Mirror: Ron-Karr goes through this in "Who Am I?" when he is revealed to be impersonating Superman to infiltrate the Legion for Imperiex.
Imperiex
Voiced by: Phil Morris Foreign VAs
- Big Bad: He is the main villain of the second season.
- Chest Blaster: He is part cyborg and has a cannon in his chest that fire an extremely powerful energy beam.
- Composite Character: His only connection to Imperiex is his name; his attributes such as being a warlord, his more human size, gray skin, implicit connection to Apokolips, and being widely feared make him out to be more similar to Darkseid.
- Conqueror from the Future: He comes to the 31st century from the 41st century.
- Dual Wield: His combat style is using two energy swords at once.
- Evil Sounds Deep: He speaks in a deep and menacing voice.
- Flat Character: Doesn't have any personality aside from wanting to conquer everything.
- From Nobody to Nightmare: Imperiex was nothing more than a slave bred for combat until he climbed his way to power.
- Galactic Conqueror: He's out to conquer the galaxy and crush anyone who stand in his way.
- Hijacked by Ganon: Ultimately, Imperiex is not the one the Legion must deal with in the end as he gets killed by the original Brainiac.
- Hoist by His Own Petard: He planned on Brainiac 5 being taken over by his predecessor to form an alliance, but then gets usurped and killed due to said attempt at an alliance.
- Impaled with Extreme Prejudice: He is stabbed in the back by Brainiac 5. While that doesn't kill him, his most powerful weapon is destroyed.
- In Name Only: Comic book Imperiex was a present-day Energy Being in a suit of armor, so giant that most of the time you were Fighting a Shadow; Animated Imperiex is a human-sized alien cyborg from 41st century.
- Knight of Cerebus: His introduction significantly darkens the series, being a far more technologically advanced, ruthless overlord than what the Legion typically deal with.
- New Era Speech: After his alliance with Brainiac is forged, he announces to the Legion that the moment he had waited for had arrived and that the carnage he would unleash would cause a ripple effect, changing all eras to come...only for Brainiac to cut him off by impaling him.
Alexis Luthor
Voiced by: Tara Strong Foreign VAs
A rich girl who befriends Superman, but is so determined to keep him that she starts attacking his friends. Not outright stated in the show, but very heavily implied to be the descendant of Lex Luthor.
- Aborted Arc: Set up to be a reoccurring villain to Superman and the Legion, but thanks to Executive Meddling ended up never appearing again, save for a brief cameo in part two of the season two premiere.
- Bald of Evil: Near the end of her debut, she gets caught in an explosion that makes her lose her hair. However, she is shown to have her hair growing back when she's later seen in jail.
- The Cameo: Makes an appearance in "Sundown" as an inmate of Takron Galtos.
- Canon Immigrant: Alexis was originally created for this show, but then she was officially introduced into the DC Universe in Grant Morrison's The Multiversity series.
- Desperately Looking for a Purpose in Life: Claims so. By the end of her episode, she decides that her purpose is to get even with the Legion. Unfortunately, she never gets another appearance beyond a cameo, so maybe she changed her mind.
- Evil Redhead: She has red hair and is very much like her ancestor Lex.
- Fiction 500: She is rich enough to own a planet, or so Saturn Girl claims.
- Jumping Off the Slippery Slope: Crosses into straight-up villainy when she tries to kill Superman over rejecting her.
- Lonely Rich Kid: She claims this is the case, but given her possessiveness once she finds a friend, one wonders if she did have friends who were chased away by her Yandere clinginess.
- Mini-Mecha: She fights in a mecha near the end of her episode.
- Never My Fault: With a nasty combination of It's All About Me. It's a Luthor thing.
- Rich Bitch: She thinks Superman spending time with her is more important than him helping the Legion with their missions.
- Yandere: She does not take Superman rejecting her well.
Dr. Londo
- Abusive Parents: If experimenting on your own son isn't abusive, then nothing is.
- Actually a Doombot: A variation occurs in "Cry Wolf" when it turns out that the Dr. Londo the Legion and Timber Wolf confront at the end of the episode is just a clone and that the real Dr. Londo has long fled the area.
- Adaptational Villainy: In the original comic series, he was only used for the purpose of flashbacks with little if any character development but when the animated series came along he may be as bad of a parent as Ozai.
- Archnemesis Dad: To Timber Wolf, if he's got an episode to himself expect Dr. Londo to be the main villain
- Evilutionary Biologist: He mutated his son and several animals in an attempt to breed formidable soldiers.
- Evil Counterpart: To President Winema Wazzo believe it or not:
- Both have titles in front of their names, related to their professions and are referred to as such (President Wazzo and Dr. Londo)
- They are single parents to their children (who're the same gender as their respective parents)
- Their children are in the Legion of Superheroes and are close friends.
- Their children resemble them in some way (for example, take away the werewolfism and his son has his facial features and hair. In a few glimpses of his son's human form he does look like a younger version of his father)
- They both meddle in their children's lives. The key difference is Winema is well-meaning and ultimately wants what's best for her daughter while Londo only is interested with what he wants and doesn't care what happens to his son, he just wants his weapon/general.
- Guinea Pig Family: He experimented on his own son.
- Jumping Off the Slippery Slope: At first appears as a lone, grieving scientist who's lost everything to the creature in the forest. As it turns out his son isn't dead but is the creature Londo told the Legion about. He also attempts to kill/capture the Legion and take his son back by force using his animal test subjects.
- Karma Houdini: One of the very few villains of the series not to be either imprisoned on Takron Galtos, sent to the Phantom Zone or killed. His second and final appearance in the series ends with him escaping from the Legion and still at large.
- Lean and Mean: He's very gaunt and quite devoid of redeeming qualities.
- Manipulative Bastard: Uses the Legion to capture his son, and during Timber Wolf's calling the old man out routine in S2 he points out that his father uses everyone this way
- Meaningful Name: His first name is Mar. The word "mar" means to harm or ruin something, which is appropriate because of how harmful his experiments were to his son and his other unwilling test subjects.
- Morally Ambiguous Doctorate: He experimented on his son and local wildlife without any concern for their well-being.
- Never My Fault: Thinks Timber Wolf should be thanking him for changing him into a werewolf-monster.
- Professor Guinea Pig He cloned himself at least three times in his second appearance
- Reverse Arm-Fold: He quite often has his arms behind his back.
- Slasher Smile: Shows this during his Villainous Breakdown when he frees his mutated animals to attack the Legion and his son. Needless to say it doesn't turn out so well, for him
- We Can Rule Together: Does this in "Cry Wolf" with his son except it involved having to use a mind controlling device and giant golems to pummel him. Great parenting.
Starfinger
Voiced by: Taylor Negron Foreign VAs
- Adaptational Comic Relief: He's more of an ineffectual goofball than any Starfinger in the comics was.
- Adaptational Wimp: The Starfingers of the comics were serious threats, while this version of the character is more of a nuisance.
- Composite Character: His appearance is modeled after the Char Burrane Starfinger, but has powers closer to those of the original Starfinger Lars Hanscom.
The Original (Spoilers)
Brainiac 1.0
Voiced by: Corey Burton Foreign VAs
- Bald of Evil: As is traditional, he has no hair. When Brainiac 5 takes damage while he's stealing his body, Brainiac 5's base body loses its hair as it undergoes repairs.
- Big Bad: Outright murders Imperiex and then takes control of his operations.
- Composite Character: He combines his comic self's color scheme with his DCAU self's voice and robotic nature.
- Enemy Within: Being Brainiac 5's predecessor, he is inevitably in his programming, but was left dormant. When Kandor was invaded by Imperiex, Brainy decided to ask for his assistance, which means Brainiac 1.0 got a foothold in his mind, which is exactly what Imperiex wanted.
- Knight of Cerebus: Perhaps even moreso than Imperiex. Namely, his first appearance in Brainiac 5's head was followed by a number of Breather Episodes, and after those were done, he then became the central antagonist in the ending two-parter.
- Not Quite Dead: After all is said and done in Season 2, it cuts back to Brainiac 1.0 putting himself back together in a new body, completely separate from Brainiac 5.Brainiac 6: Evil does not die. It evolves.
- Red Eyes, Take Warning: He has red eyes and it should be a clue to be wary of him.
- Secondary Color Nemesis: Green "skin", purple armor.
- Villainous Breakdown: He starts attacking far more aggressively when Brainiac 5 gains control again, and then screams after being impaled.
- Walking Spoiler: It's difficult to bring him up without spoiling how the second season ends.
Allies
President Wazzo
Voiced by: April Winchell Foreign VAs
- Adaptational Nice Guy: In the Reboot comics, where the idea of her being a politician and significant character comes from, she despises the Legion, at least initially, seeing them as a bunch of criminals corrupting her daughter, and does everything in her power to get them shut down.
- Amazingly Embarrassing Parents: Her daughter gets annoyed whenever she goads her to ask boys out.
- Doting Parent: She loves her daughter dearly.
- Good Counterpart: To Dr. Londo.
- Family Eye Resemblance: Gray eyes like mother, like daughter.

When she thought her daughter was dating Superman, she encouraged their pairing and then immediately tried to ship her with another boy when she thought they broke up.
- Reasonable Authority Figure: She knows that her daughter and the other Legionnaires are doing the right thing.
