The character sheet for the animated series ''WesternAnimation/LegionOfSuperHeroes''.
->Voiced by: Creator/YuriLowenthal

* {{Badass}}: He's Superman, after all. Despite being younger than most of his traditional adaptations, he is still a capable fighter.
* 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: One of the most famous examples in fiction.
* ExtremityExtremist: Whenever he fights, Superman almost exclusively uses his fists.
* FishOutOfWater: Both as a [[HumanAliens Kryptonian]] and as someone from the past.
* FlyingBrick: Of course.
* [[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.
* 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.
* PrimaryColorChampion: Naturally.
* RedOniBlueOni: The Blue to Superman X's Red.
* RookieRedRanger
* SuperpowerLottery: He wouldn't be Superman without this trope.

!Lightning Lad
->Voiced by: Andy Milder

* ArtificialArm: From "Chained Lightning" onwards.
* BadassBeard: In season two.
* 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's 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
* 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's under eye mark.
* [[SheIsAllGrownUp He's All Grown Up]]: Has a shirtless scene in ''Chained Lightning'' to demonstrate this. Much to the joy of Legion fangirls everywhere.
* JerkWithAHeartOfGold: While still this in season two, he'd softened a little. Not majorly, but considerably.
* TheLancer
* LockedIntoStrangeness: His scar and eyes are a result of the Lightning Beasts shocking him and his siblings that granted them their abilities.
* MajorInjuryUnderReaction: ''"Sweet"''.
* 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
* 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.

!Saturn Girl
->Voiced by: Creator/KariWahlgren

* ActionGirl
* BigOlEyebrows
* CaptainObvious
* TheChick
* 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
* MindControlEyes: Her eye's glow whenever she uses her physic abilities.
* MindOverManners: Lighting 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.
* PsychicPowers
* PurpleEyes
* RapunzelHair
* TechnicolorEyes
* [[TelepathicSpacemen Telepathic Spacegirl]]

!Brainiac 5
->Voiced by: Adam Wylie

* AdorablyPrecociousChild
* AmbiguouslyGay
* [[spoiler: BrainwashedAndCrazy: When Brainiac 1.0 takes control of him.]]
* DoAnythingRobot
* [[GreenSkinnedSpaceBabe Green Skinned Space Guy]]: He's not exactly [[MsFanservice Mr. Fanservice]], but that hasn't stopped his horde of fangirls.
* GeniusBruiser The genius part is blatantly obvious, the bruiser part comes in when he turns into his "battle mode"
** Read: 12 foot tall mecha that has enough dakka to make someone supposedly "armed to the teeth" and member of the bad guys who took the whole legion to run like a little girl
* 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 NotSoDifferent than Brainiac 1... and that's all 1.0 needed.]]
* InSeriesNickname: "Brainy".
* InsufferableGenius: He comes off as this to the rest of the Legion at times when his TechnoBabble becomes tiresome
* LegacyCharacter
* 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
* MechanicalLifeform
* OutOfCharacterMoment: His entire character after the first few minutes of "Brain Drain" due to a malfunction. HilarityEnsues.

* PragmaticHero
* PurpleEyes
* RobotBuddy
* SecretKeeper
* TheSmartGuy
* TheSpock
* SpockSpeak
* TelescopingRobot
* [[spoiler: WellIntentionedExtremist]]

* BigFun
* TheBigGuy

* GenreSavvy: Comes with being an ancient horror movie fanboy
* PluckyComicRelief
* 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.

!Phantom Girl
->Voiced by: Creator/HeatherHoganWatson

* ActionGirl
* DeadpanSnarker
* EeriePaleSkinnedBrunette: She's much paler than the other girls in the show, and the design of her costume and face suggest a skull.
* GrayEyes: 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]]
* LittleMissSnarker
* ScrewTheRulesImDoingWhatsRight: When she aids [[spoiler: Timber Wolf]] despite the Legion's laws.
* ShipTease: With [[BeastAndBeauty Timber Wolf]]
* SpoiledSweet: Her mom's president of the galaxy, in case you didn't know.
* ThisLooksLikeAJobForAquaman: [[spoiler: Is the most powerful legionnaire in the phantom zone.]]

!Timber Wolf
->Voiced by: Shawn Harrison

* BadAss: In his first appearance he trashed his Dad's lab in response to what he had done to him when he was younger and kept kicking ass even after joining the Legion. Even theirs on one occasion.
* 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]]
* DeadpanSnarker
* GuineaPigFamily: See [[AbusiveParents Abusive Parents]]
* GutturalGrowler: ''Especially'' when he's in his bestial form.
* HiddenDepths: He likes to cook.
* LightningBruiser: In S2 he's built like a tank, and although he's not as fast as speedsters or even 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
* OurWerewolvesAreDifferent
* RealMenWearPink: See HiddenDepths
* 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]].
* SkunkStripe: Like his father
* SlasherSmile: Does this in Cry Wolf where [[spoiler: the nanites have taken control over him]]
* SixthRanger
* TheStoic
* SupernaturalGoldEyes: The lupine sort.
* VomitDiscretionShot: 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.

* DespairEventHorizon: When [[spoiler: one of the duplicates is seemingly killed]].

%%* VoluntaryShapeshifting

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

* AntiHeroSubstitute
** {{Adorkable}}: His upbringing changed a lot but he retains a lot of Superman's personality traits and has just as awkward as a time fitting in with society.
%%* CloningBlues
* CompositeCharacter: Kon-El and Superman from the 853rd century.
* 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.
%%* GoodIsNotNice
%%* GreenEyes
%%* LaserGuidedTykebomb
%%* TheOnlyOneAllowedToDefeatYou
* RedOniBlueOni: The Red to Superman's Blue.

!Cosmic Boy
->Voiced by: Creator/WilWheaton

* WhatTheHellHero: 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: Creator/KariWahlgren

* AnnoyingLaugh: She's a snorter
* [[spoiler: GiantEqualsInvincible [[MouseWorld In Kandor]]]]
* GeniusBruiser: [[ComicBook/AntMan This type]] [[ComicBook/TheAtom tends to be.]] That she is able to keep Braniac 5 in check is probably why her teammates tolerate the other tropes listed here.
%%* ObnoxiousSnarker
* ShipTease: She seems to spend a lot of time with Braniac 5.
* ShrinkingViolet: Averted, visually she gets smaller and wears dark purple but she does not have this personality at all.

* HeelFaceTurn: [[spoiler: Although they weren't seen after their "turns", Lightning Lord and Ron-Karr.]]
* 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.]]

-> Voiced by: Creator/Phil Morris

* BigBad: of season 2.
* ConquerorFromTheFuture
* GenericDoomsdayVillain
* [[spoiler: [[HijackedByGanon Hijacked by Brainiac]]: Ultimately, Imperiex is not the one the Legion must deal with in the end.]]
* 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.]]
* InNameOnly: Comicbook 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.

!Alexis Luthor
-> Voiced by: Creator/TaraStrong

* BaldOfEvil: Fitting, being a Luthor.
* 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
* {{Fiction 500}}: She owns a planet
* JumpingOffTheSlipperySlope
* LonelyRichKid
* MiniMecha
* NeverMyFault: It's a Luthor thing.
* RichBitch
* {{Yandere}}

!Dr. Londo
-> Voiced by: Harry Lennix (Season 1), Dorian Harewood (Season 2)

* [[AbusiveParents Abusive Dad]]
* ArchnemesisDad: To Timber Wolf, if he's got an episode to himself expect Dr. Londo to be the main villain
* EvilutionaryBiologist
* 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.
* FromNobodyToNightmare: 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]]
* GuineaPigFamily
* 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 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
* 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: Dr. ''Mar'' Londo
* MorallyAmbiguousDoctorate
* NeverMyFault: Thinks Timber Wolf should be ''thanking'' him for changing him into a werewolf-monster.
* ProfessorGuineaPig [[spoiler: cloned himself at least three times in his second appearance]]
* ReverseArmFold
* 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.]]

![[spoiler: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.]]
* [[spoiler: EnemyWithin: 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.]]
* VillainousBreakdown: [[spoiler: He starts attacking far more aggressively when Brainiac 5 gains control again, and then screams after being impaled.]]
* WalkingSpoiler
