->'''[=L3W=]'''--''Legion of Three Worlds'', a ''ComicBook/FinalCrisis'' limited series bringing together the Retroboot, Postboot, and Threeboot Legions.

The ''ComicBook/{{Legion of Super-Heroes}}'' has been ongoing in one form or another since 1958, encompassing three completely distinct continuities and several more "branch" continuities. That being the case, there are many alternate versions and a lot of CharacterDevelopment involved, and what tropes apply to what characters varies from version to version. Here's a thumbnail reference for what refers to what part of continuity:

!The Legion of Super-Heroes
[[folder:Superman]]
!Franchise/{{Superman}} (Clark Kent)
[[quoteright:370:https://static.tvtropes.org/pmwiki/pub/images/f3e93eaa3c79ea04d1bbf3d46af0742b.jpg]]
->Voiced by: Creator/YuriLowenthal

Power set: Super-strength and durability, heat vision, freezing breath. Can fly even without his Legionnaire ring... but not very well.
----
* AdaptationalNameChange: Due to legal issues with the Superboy name, he's simply referred to as Superman
* BadassCape: Would he really be Superman without the iconic red cape?
* ClarkKenting: TropeNamer. 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 [[JustifiedTrope 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.
* ChestInsignia: Wouldn't be Superman without the S on his chest.
* DisneyDeath: 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.
* ExtremityExtremist: Whenever he fights, Superman almost exclusively uses his fists.
* FishOutOfWater: Both as a [[HumanAliens Kryptonian]] and as someone from the past.
* FlyingBrick: He can fly and is very formidable.
* [[SheIsAllGrownUp He's All Grown Up]]: In season two, WOW.
-->'''Superman''': "Who you calling skinny?"
* InnocentBlueEyes: Of the "heroic and idealistic" variety.
* TheLeader: He is not officially leader but the Legion defer to his judgment, if only out of respect to his heroic legacy.
* MessianicArchetype: Superman becomes this in "Dark Victory" and serves as much for the Legion as its resident HopeBringer 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.
* NaiveNewcomer: When he's first introduced but he gets to grips with it pretty quickly.
* NiceGuy: Hands down the nicest character in the show. He even attempts to convince [[JerkWithAHeartOfGold Superman X]] about the values of [[ThePowerOfFriendship friendship]] and [[TrueCompanions teamwork]].
* OutOfFocus: In the second season, more attention is given to his successor Superman X. As a result, he appears much less frequently.
* PrimaryColorChampion: Naturally. His costume has red, blue, and yellow and he's a very powerful hero.
* RedOniBlueOni: The Blue to Superman X's Red.
* RookieRedRanger: He is recruited by the Legion to help them take down the Fatal Five when they overpowered them.
* SuperpowerLottery: He wouldn't be Superman without this trope.
* WritingAroundTrademarks: 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).
[[/folder]]

[[folder:Lightning Lad]]
!Lightning Lad
->Voiced by: Andy Milder

Power set: Here's a hint: he's not named Non-Electrocuting Lad.
----
* ArtificialLimbs: From "Chained Lightning" onwards, he gets a robotic arm after his original one got blasted off by Imperiex.
* BadassBeard: In season two, he has a beard.
* ButtMonkey: 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.
* CainAndAbel: The Abel to Mekt's Cain.
* CynicismCatalyst: 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 CainAndAbel complex, along with Garth's cynical attitude and Mekt's path into villainy. [[spoiler: Subverted in that she didn't die at all and was eventually restored to a physical form]].
* FieryRedhead: He has red hair and is often short-tempered.
* GoodParents: 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.
* GoodScarsEvilScars: Lightning Lad has a lightning bolt-shaped scar over one of his eyes.
* [[SheIsAllGrownUp He's All Grown Up]]: Has a shirtless scene in ''Chained Lightning'' to demonstrate this.
* JerkWithAHeartOfGold: He's arrogant and raucous, but he still fights for what is right.
* TheLancer: Becomes the second-in-command when Superman joins the team.
* LockedIntoStrangeness: His scar and eyes are a result of the Lightning Beast shocking him and his siblings that granted them their abilities.
* MajorInjuryUnderReaction: 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.
* RealMenWearPink: 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, [[spoiler: formerly twin]] sister dearly.
* ShockAndAwe: His power is firing bolts of electricity.
* TeethClenchedTeamwork: 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 [[spoiler: 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.
* TookALevelInKindness: He develops a very noticeable soft side in the second season. [[spoiler: He's overjoyed to be reunited with his sister Ayla, and is happy that her return prompts Mekt to do a HeelFaceTurn]]. 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.
[[/folder]]

[[folder:Saturn Girl]]
!Saturn Girl
->Voiced by: Creator/KariWahlgren

Power set: ESP and telepathy; projection of psychic illusions.
----
* ActionGirl: She gets to join in the action frequently as one of the team's core members.
* BigOlEyebrows: Her eyebrows are very prominent.
%%* CaptainObvious
%%* TheChick
* HumanoidAlien: Clearly not quite human, but very similar.
* TheHeart: She's quite good at handling people. She did show a great deal of compassion for Timber Wolf before his true identity was revealed.
* MasterOfIllusion: She can use her telepathic abilities to trick people into seeing things that aren't really there.
* MindControlEyes: Her eyes glow whenever she uses her psychic abilities.
* MindOverManners: 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.
* OutOfFocus: She appeared less frequently during season two.
* PsychicPowers: Her main power is telepathy.
* RapunzelHair: Her hair is long.
* TechnicolorEyes: She has violet eyes.
* [[TelepathicSpacemen Telepathic Spacegirl]]: She is an alien and she has mental powers.
[[/folder]]

[[folder:Brainiac 5]]
!Brainiac 5
->Voiced by: Creator/AdamWylie

Power set: Super-intelligence along with extensible limbs, reprogramming computers by touch, limited shape-shifting, and the RequiredSecondaryPowers of a synthetic being.
----
* AdaptationalBadass: 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 DoAnythingRobot complete with his super-intellgence who can take down the entire Legion, his home planet, and overcome the galaxy itself if he wanted to.
* AdorablyPrecociousChild: An adolescent who acts more mature than his teammates.
* AmbiguouslyGay: His devotion to Superman sometimes comes off as more than just mere admiration.
* [[spoiler: BrainwashedAndCrazy: When Brainiac 1.0 takes control of him.]]
* DoAnythingRobot: He has a robotic body and he can transform his arms into any tool or weapon needed.
* [[GreenSkinnedSpaceBabe Green Skinned Space Guy]]: He's not exactly [[MsFanservice Mr. Fanservice]], but that hasn't stopped his horde of fangirls.
* GadgeteerGenius: 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.
* GeniusBruiser The genius part is blatantly obvious, the bruiser part comes in when he takes on a twelve-foot 'battle form'.
* IDidWhatIHadToDo: 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.
** Pointed out by [[spoiler: 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.]]
* InSeriesNickname: His teammates frequently address him as "Brainy".
* InsufferableGenius: He comes off as this to the rest of the Legion at times when his TechnoBabble becomes tiresome
* LegacyCharacter: He is a descendant of the original Brainiac, one of Superman's enemies.
* LockedIntoStrangeness: 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.
* LosingYourHead: For most of the episode "Brain Drain", a teleportation mishap results in his head being separated from his body.
* MechanicalLifeform: He is an android, but also acts human.
* OutOfCharacterMoment: His entire character after the first few minutes of "Brain Drain" due to a malfunction. HilarityEnsues.
* PinocchioSyndrome: Per WordOfGod.
* PragmaticHero: "Phantoms" reveals he has a piece of kryptonite around, which would be sensible in case Superman went rogue. He also justifies [[spoiler: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 [[DeconstructedTrope 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.
* RobotBuddy: He is an android and gets along well with the other Legionnaires.
* TheSmartGuy: He is the brains of the team.
* TheSpock: 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.
* SpockSpeak: Part of his intellectual personality is using technical terms while speaking in a serious tone of voice.
* TechnicolorEyes: His eyes are purple.
* TelescopingRobot: He can extend his neck and limbs.
* WellIntentionedExtremist: Comes off as this when he is [[spoiler:controlled by Brainiac 1.0]] in "Dark Victory", claiming that with his order he can end suffering and prevent everything from falling into chaos.
[[/folder]]

[[folder:Bouncing Boy]]
!Bouncing Boy
->Voiced by: Michael Cornacchia

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.
* AscendedFanboy: Was a fan of the LOSH and tried for years to be a member. He eventually succeeded and became their leader for some time.
* BigEater: The first episode alone makes it clear that he loves food. For instance, he's quite thrilled to discover hot dogs and cotton candy.
* BigFun: 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.
* TheBigGuy: He quite often uses his bouncing ability to break through barriers and pummel his enemies.
* TheChainsOfCommanding: Feels them when he gets put in charge of the Legion.
* DarkHorseVictory: 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.
* GenreSavvy: Comes with being an ancient horror movie fanboy. He's also quite savvy of villain schemes due to being a movie buff.
* PluckyComicRelief: He serves as the jokester of the group.
* HyperDestructiveBouncingBall: He IS one!
* MissionControl: When he is piloting and the others are in action. Exceptional work at this briefly gets him elected leader of the entire Legion.
* ShipTease: With Triplicate Girl.
* WhatKindOfLamePowerIsHeartAnyway: He was rejected from the Legion four times before finally being let in.
** HeartIsAnAwesomePower: He was let in eventually and is a useful member of the team by the time of the show.

[[folder:Phantom Girl]]
!Phantom Girl
[[quoteright:283:https://static.tvtropes.org/pmwiki/pub/images/phantom_girl.jpg]]
%%[[caption-width-right:283:some caption text]]
->Voiced by: Creator/HeatherHoganWatson

Power set: Well-controlled insubstantiality: the ability to induce insubstantiality in other people or matter.
----
* ActionGirl: One of the team's core members, she's often involved in the action.
* DeadpanSnarker
* EeriePaleSkinnedBrunette: She's much paler than the other girls in the show, and the design of her costume and face suggest a skull.
* FamilyEyeResemblance: Has gray eyes just like her mother's.
* TheHeart: Served this to Lightning Lad and Timber Wolf when both were dangerously close to becoming murderers.
* [[IntangibleMan Intangible Girl]]: Her power is phasing through solid objects.
* LittleMissSnarker
* OutOfFocus: Like Saturn Girl, Phantom Girl received less screentime in season 2 because of ExecutiveMeddling.
* ScrewTheRulesImDoingWhatsRight: When she aids [[spoiler: Timber Wolf]] despite the Legion's laws.
* ShipTease: With [[BeastAndBeauty Timber Wolf]] though she also has some romantic leanings for Ultra Boy.
* ThisLooksLikeAJobForAquaman: [[spoiler:She's the most powerful Legionnaire in the Phantom Zone.]]
* WellExcuseMePrincess: 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 [[ImpliedLoveInterest Timber Wolf]].
[[/folder]]

[[folder:Timber Wolf]]
!Timber Wolf
->Voiced by: Shawn Harrison

Power set: Strength, speed, and durability. Becomes considerably more dangerous, in every sense, when enraged.
----
* BrainwashedAndCrazy: [[spoiler: [[SarcasmMode Daddy dearest]] used his nanites to turn him into this, it was seeing Phantom Girl's unconscious body that snapped him out of it]].
* CallingTheOldManOut: Gives his pop a few of these.
* ClearMyName: [[spoiler: Was accused of killing [[SelfMadeOrphan 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]].
* DangerousForbiddenTechnique: Timberwolf regards his alternate form as extremely hazardous, partly because he has no control over shifting back.
* DeadpanSnarker
* GuineaPigFamily: See [[AbusiveParents Abusive Parents]].
* GutturalGrowler: ''Especially'' when he's in his bestial form.
* HiddenDepths: He likes to cook. He particularly likes [[RealMenWearPink to bake cookies for his teammates.]]
* LightningBruiser: 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.
* LockedIntoStrangeness: 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.
* MisunderstoodLonerWithAHeartOfGold: 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.
* OurWerewolvesAreDifferent: He became a wolf-like humanoid because his father experimented on him.
* ResistTheBeast: In "Cry Wolf" he does experience this trope and trying hard not to revert into his [[SuperPoweredEvilSide bestial form]] [[spoiler: in one such instance he was struggling with his monster form when Phantom Girl tries to coax him back to normal...until the [[InterruptedCooldownHug 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.]]
* ShipTease: With [[BeastAndBeauty Phantom Girl]].

* SixthRanger: Joins the team by the end of his first appearance.
* TheStoic: Often has a serious demeanor.
* SupernaturalGoldEyes: The lupine sort.

* WolfMan: He's a humanoid wolf.
* YouWouldntLikeMeWhenImAngry: When angered, he becomes larger, more monstrous, and more aggressive.
[[/folder]]

[[folder:Triplicate Girl]]

Power set: Self-duplication, some martial arts skills.
----
* ActionGirl: She often appears on the scene to lend a hand during the team's battles.
* BareYourMidriff: She wears this for the first series then only partially for the second series.
* DespairEventHorizon: When [[spoiler: one of the duplicates is seemingly killed]].
* GenkiGirl: The most peppy and excitable of the female Legion members.
* LiteralSplitPersonality: 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.
* MagicSkirt: In spite of how short her skirt is, it never changes position.
* MesACrowd: 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.
* PeekABangs: Part of her hair covers one of her eyes.
* StatusQuoIsGod: After being [[spoiler: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 [[spoiler:reuniting with her restored third self.]]
* YouGottaHaveBlueHair: Her individual triplicate selves have white, orange, and purple hair. When she's whole, her hair has all three colors.
[[/folder]]

[[folder:Chameleon Boy]]
!Chameleon Boy
-> Voiced by: Alexander Polinsky

Power set: Shape-shifting.
----
* DeadpanSnarker: Most notably in regards to Karate Kid's optimism.
* HeroWorshipper: In 'Who Am I' it was shown he's idolized Superman for years before he even joined the Legion.
* InSeriesNickname: He is often addressed as Cham.
* {{Keet}}: He is very energetic.
* KidAppealCharacter: He's mainly introduced in the second season because the other Legionnaires have become serious and more mature after the TimeSkip.
* MagicPants: His clothes disappear whenever he shapeshifts, but he somehow still has his clothes whenever he returns to his normal form.
* MemoryGambit: 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.
* PluckyComicRelief: Good-natured and fond of puns.
* VoluntaryShapeshifting: His power is changing himself into any living thing.
[[/folder]]

[[folder:Ferro Lad]]
!Ferro Lad
->Voiced by: Creator/DaveWittenberg

Power set: Ability to turn his body into living iron that increases his strength and endurance.

----
* ExtraOreDinary: His superpower turns him into living iron.
* FacialHorror: He says to Lightning Lad he's doing everyone a favor by wearing his mask.
* HeroicSacrifice: 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.
* SacrificialLion: As a nod to the comics, he sacrifices his life to save the legion in the Season One finale.
* SuperStrength and SuperToughness: In iron form.

[[/folder]]

[[folder:Superman X]]
!Superman X[=/=]Kell-El
->Voiced by: Creator/YuriLowenthal

Power set: Super-strength, invulnerability, heat vision, cold breath, flight.
----
* AntiHeroSubstitute: 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.
* AlternativeSelfNameChange: To differentiate him from Superman, everybody chooses to refer to him as Kell-El.
* BladeBelowTheShoulder: Can form energy from the back of his hands.
* CloningBlues: He is cloned from Superman's DNA and is frustrated that the Legion find the original Superman superior to him.
* CompositeCharacter: 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). Having Superman's powers but an immunity to Kryptonite also makes him similar to Mon-El/Lar Gand.
* GeneticEngineeringIsTheNewNuke: 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.
* GemstoneAssault: Thanks to the Kryptonite into his DNA he can summon crystal structures to surround and bind his enemies.
* GoodIsNotNice: 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.
* LaserGuidedTykebomb: He was created to stop Imperiex.
* TheOnlyOneAllowedToDefeatYou: He doesn't want anyone else to defeat Imperiex.
* OneHeroHoldTheWeaksauce: Kryptonite is mixed into his DNA; as a result, he's immune to it.
* SuperpowerLottery: In addition to the standard Kryptonian powers, he is immune to Kryptonite.
* RedOniBlueOni: The Red to Superman's Blue.

[[folder:Cosmic Boy]]
!ComicBook/CosmicBoy
->Voiced by: Creator/WilWheaton

Power set: [[MagnetismManipulation Metal control]].
----
%%* AlwaysSomeoneBetter
%%* ByTheBookCop
* TheCaptain: He is the de facto leader of the Legion of Super Heroes.
* DemotedToExtra: In the comics he's one of the most prominent members of the legion and is generally part of a TwoGuysAndAGirl trio with Lightning Lad and Saturn Girl. Here his role is much less prominent.
* ExtraOredinary: He can manipulate metal.
* GoodIsNotNice: 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.
* UnresolvedSexualTension: 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.
* WhatTheHellHero: Lightning Lad calls him out for not even having the time to visit Saturn Girl while she's in a temporary coma.
[[/folder]]

[[folder:Shrinking Violet]]
!Shrinking Violet
->Voiced by: Creator/KariWahlgren

Power set: Shrinking.
----
* GeniusBruiser: [[ComicBook/AntMan This type]] [[ComicBook/TheAtom tends to be.]] That she is able to keep Brainiac 5 in check is probably why her teammates tolerate the other tropes listed here.
* ShipTease: She seems to spend a lot of time with Brainiac 5.
* ShrinkingViolet: Averted in spite of her name, visually she gets smaller and wears dark purple but she does not have this personality at all.
* TheNapoleon: She's very sensitive about her height.
* WhatKindOfLamePowerIsHeartAnyway: Though she thinks shrinking is the best power.
* RavenHairIvorySkin: Unlike the comic version.

!Villains

[[folder:The Fatal Five]]
!The Fatal Five
----
* AdaptationalEarlyAppearance: 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 "NiceJobBreakingItHero" as it was how the group formed, whereas the group was already active well before that point.
* FiveManBand
** BigBad: Emerald Empress is the leader of the group.
** TheDragon: Persuader
** EvilGenius: Tharok is said to be as smart as Brainiac 5.
** TheBrute: Validus. Later becomes TheDragon to Imperiex, yet is TheBrute while in the Fatal Five.

* JerkJock: Mekt "Lightning Lord" Ranzz in "Champions", before joining the LSV.
* JumpingOffTheSlipperySlope: The Light Speed Vanguard at first seem Cooler And More Effective Heroes, then Kinda Selfish Mercenary Heroes, then Ruthless Protection Racket.
* LockedIntoStrangeness: Like his brother the Lightning Beasts shocked him and his eyes and hair changed.
* MoralityPet: [[spoiler:for Mekt in "Chained Lightning". Many years ago, dead little sister. Then, NotQuiteDead (which puts EvenEvilHasLovedOnes back into play), followed by UnexplainedRecovery. As he directly contributes to Ayla's restoration, he surrenders to prison without a fight.]]
* PsychoRangers: 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.

* ChestBlaster: He is part cyborg and has [[WaveMotionGun a cannon in his chest that fire an extremely powerful energy beam]].
* CompositeCharacter: His only connection to Imperiex is [[InNameOnly his name]]; his attributes such as being a warlord, his more human size, gray skin, implicit connection to Apokolips, and being [[TheDreaded widely feared]] make him out to be more similar to {{ComicBook/Darkseid}}.
* ConquerorFromTheFuture: He comes to the 31st century from the 41st century.
* DualWield: His combat style is using two energy swords at once.
* EvilSoundsDeep: He speaks in a deep and menacing voice.
* FromNobodyToNightmare: Imperiex was nothing more than a slave bred for combat until he climbed his way to [[GalacticConqueror power]].
* GalacticConqueror: He's out to conquer the galaxy and crush anyone who stand in his way.
* GenericDoomsdayVillain: Doesn't have any personality aside from wanting to conquer everything.
* HijackedByGanon: [[spoiler:Ultimately, Imperiex is not the one the Legion must deal with in the end as he gets killed by the original Brainiac.]]
* HoistByHisOwnPetard: [[spoiler:He planned on Brainiac 5 being taken over by his predecessor to form an alliance, but then [[HijackedByGanon gets usurped and killed]] due to said attempt at an alliance.]]
* ImpaledWithExtremePrejudice: [[spoiler:He is stabbed in the back by Brainiac 5. While that doesn't kill him, [[ChestBlaster his most powerful weapon is destroyed]].]]
* InNameOnly: Comic book Imperiex was a present-day EnergyBeing in a suit of armor, so giant that most of the time you were FightingAShadow; Animated Imperiex is a human-sized alien cyborg from 41st century.
* KnightOfCerebus: His introduction significantly darkens the series, being a far more technologically advanced, ruthless overlord than what the Legion typically deal with.
* NewEraSpeech: [[spoiler: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]].

[[folder:Alexis Luthor]]
!Alexis Luthor
-> Voiced by: Creator/TaraStrong
----
* BaldOfEvil: 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.
* TheCameo: Makes an appearance in "Sundown" as an inmate of Takron Galtos.
* CanonImmigrant: Alexis was originally created for this show, but then she was officially introduced into the Franchise/DCUniverse in Creator/GrantMorrison's ''Comicbook/TheMultiversity'' series.
* DesperatelyLookingForAPurposeInLife: 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 [[EpicFail maybe she changed her mind.]]
* EvilRedhead: 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.
* JumpingOffTheSlipperySlope: Crosses into straight-up villainy when she tries to kill Superman over rejecting her.
* LonelyRichKid: 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.
* MiniMecha: She fights in a mecha near the end of her episode.
* NeverMyFault: With a nasty combination of ItsAllAboutMe. It's a Luthor thing.
* RichBitch: 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.

[[folder:Dr. Londo]]
!Dr. Londo
-> Voiced by: Creator/HarryLennix (Season 1), Creator/DorianHarewood (Season 2)
----
* [[AbusiveParents Abusive Dad]]: If ''experimenting on your own son'' isn't abusive, then nothing is.
* ActuallyADoombot: A variation occurs in "Cry Wolf" when [[spoiler: 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.]]
* AdaptationalVillainy: 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 [[WesternAnimation/AvatarTheLastAirbender Ozai]].
* ArchnemesisDad: To Timber Wolf, if he's got an episode to himself expect Dr. Londo to be the main villain
* EvilutionaryBiologist: He mutated his son and several animals in an attempt to breed formidable soldiers.
* EvilCounterpart: 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.
* GuineaPigFamily: He experimented on his own son.
* JumpingOffTheSlipperySlope: 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.
* KarmaHoudini: 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.
* LeanAndMean: He's very gaunt and quite devoid of redeeming qualities.
* ManipulativeBastard: Uses the Legion to capture his son, and during Timber Wolf's [[CallingTheOldManOut calling the old man out routine]] in S2 he points out that his father uses everyone this way
* MeaningfulName: 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.
* MorallyAmbiguousDoctorate: He experimented on his son and local wildlife without any concern for their well-being.
* NeverMyFault: Thinks Timber Wolf should be ''thanking'' him for changing him into a werewolf-monster.
* ProfessorGuineaPig [[spoiler: He cloned himself at least three times in his second appearance]]
* ReverseArmFold: He quite often has his arms behind his back.
* SkunkStripe: Like father, like son
* SlasherSmile: Shows this during his VillainousBreakdown when he frees his mutated animals to attack the Legion and his son. [[TheDogBitesBack Needless to say it doesn't turn out so well, for him]]
* WeCanRuleTogether: Does this in "Cry Wolf" with his son except it involved having to use a mind controlling device and giant golems to pummel him. [[SarcasmMode Great parenting.]]

[[folder:'''SPOILER character for Season 2''']]
!Brainiac 1.0
->Voiced by: Creator/CoreyBurton
----
* BaldOfEvil: [[spoiler: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.]]
* BigBad: [[spoiler: Outright ''murders'' Imperiex and then takes control of his operations.]]
* CompositeCharacter: He combines his comic self's color scheme with his [[spoiler: DCAU self's voice and robotic nature.]]
* EnemyWithin: [[spoiler: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.]]
* KnightOfCerebus: Perhaps even moreso than Imperiex. [[spoiler:Namely, his first appearance in Brainiac 5's head was followed by a number of {{Breather Episode}}s, and after those were done, he then became the central antagonist in the ending two-parter.]]
* NotQuiteDead: [[spoiler: 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.]]
-->[[spoiler: '''Brainiac 6:''' Evil does not die. [[EvilEvolves It evolves.]]]]
* RedEyesTakeWarning: He has red eyes and it should be a clue to be wary of him.
* SecondaryColorNemesis: [[spoiler: Green "skin", purple armor.]]
* VillainousBreakdown: [[spoiler: He starts attacking far more aggressively when Brainiac 5 gains control again, and then screams after being impaled.]]
* WalkingSpoiler: It's difficult to bring him up without spoiling how the second season ends.

* FamilyEyeResemblance: Gray eyes like mother, like daughter.
* MamaBear: Defended her daughter against a CorruptCorporateExecutive in the ''Legion of Superheroes'' comic adaptation of the TV series.
* MeddlingParents: She means well but she's ''very'' interested in her daughter's dating life and tries to set her up with any boy she thinks is cute. 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.
* ReasonableAuthorityFigure: She knows that her daughter and the other Legionnaires are doing the right thing.

* OutOfFocus: Received less screentime in season 2 because of ExecutiveMeddling.

** Pointed out by [[spoiler: 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 NotSoDifferent than Brainiac 1... and that's all 1.0 needed.]]

* [[SheIsAllGrownUp He's All Grown Up]]: Has a shirtless scene in ''Chained Lightning'' to demonstrate this. Much to the joy of Legion fangirls everywhere.

* DemotedToExtra: In the comics he's one of the most prominent members of the legion and is generally part of a trio with Lightning Lad and Saturn Girl. Here his role is much less prominent.
