[[folder:The Bat Family]]

!! Bruce Wayne/Batman
--> '''Voiced by:''' Creator/RinoRomano

--> ''"Let's hope it's not the Batman that brings out the freaks..."''

Son of wealthy entrepreneurs Thomas and Martha Wayne, who were gunned down one evening coming out of a theater as a young Bruce watched. Vowing to take revenge on the criminal underworld, he spent years abroad to hone mind and body so he could act as Gotham City's midnight vigilante, using stealth and the imagery of a bat to intimidate his prey. He is the CEO of Waynetech, developer of technologies such as his elite crimefighting vehicle and a device called the "Bat-Wave". ''The Batman'' follows a 26-year old Bruce during the adventures in his third year as Batman.

* BadassBaritone: While in his Batman guise.
* BadassNormal
* [[spoiler:BrainwashedAndCrazy]]: In the second part of "Batgirl Begins", temporarily.
* BruceWayneHeldHostage: TropeNamer.
* CoolCar: The Batmobile, as always.
* CrazyPrepared: A staple of Batman.
* DarkIsNotEvil: Of course.
* DeadpanSnarker: You'd never believe it, but this Batman gives his fare share of one-liners. To the point where it almost becomes YouFightLikeACow. Almost. In "Topsy-Turvy", he and Joker even had a little SnarkToSnarkCombat.
* EasyAmnesia: Gets this in "A Dark Knight To Remember".
* ExpressiveMask: His eye slits widen or narrow with emotion.
* GoodCannotComprehendEvil: Usually Batman understands his villains, but when he goes inside the Joker's mind, he is nearly driven insane.
* HeroWithBadPublicity: In the first two seasons, where the police consider him a VigilanteMan at best.
* {{Jetpack}}: Uses one as Batman to fight aerial villains like Firefly and Man-Bat.
* LaserGuidedAmnesia: In "A Dark Knight To Remember", thanks to a bump to the head.
* MarriedToTheJob: Literally stated by Alfred in one episode.
* NotAsYouKnowThem: In the Season 5 premiere, it's he, and ''not'' Superman, who's more willing to team-up.
* ParentalAbandonment: Yeah, okay, you all know what's coming. [[MemeticMutation HIS PARENTS ARE DEEAAAAAAAD!]] But worse, [[spoiler:his parents' killer was never brought to justice]].
* RichIdiotWithNoDayJob: As usual.
* ThouShaltNotKill: [[spoiler:Though this rule can be bent, like when he kills the undead Dracula or the robotic D.A.V.E.]]
* TookALevelInBadass: With each passing season. In the first season he was a clueless newbie, and later on he's much closer to his comic counterpart.
* WhereDoesHeGetAllThoseWonderfulToys: Lucius Fox.
* WouldHitAGirl: [[http://www.youtube.com/watch?v=r6m9cL3Tsgk&feature=related You knew she was a plant, right?]]
* YoungerAndHipper: The first season had a very young Batman, who was new to the superhero job and in his twenties at the latest.

!! Alfred Pennyworth
--> '''Voiced by:''' Alastair Duncan

The Wayne family's loyal retainer who saw Bruce through his emotionally dark childhood following the murder of his parents. He is privy to Bruce's secret identity as Batman and maintains the Batcave whilst Bruce is in the field.

* CharacterDevelopment: In the early episodes, Alfred wasn't too happy with Bruce's work, often suggesting he give it up. By the time of the season three episode "Gotham's Ultimate Criminal Mastermind", his opinion had changed considerably, to the point where he was willing to die rather then have Bruce's secret be revealed.
-->"Gotham needs the Batman more then you need a butler!"
* CoolOldGuy: In "Artifacts".
* DeadpanSnarker: This ''is'' Alfred.
* TheJeeves: As usual.
* TheMedic: As usual.
* ParentalSubstitute: He raised Bruce after his aprents died.
* SecretKeeper: As usual.
* ServileSnarker: As always.
* UndyingLoyalty: To Batman.

!! Barbara Gordon/Batgirl
--> '''Voiced by:''' Creator/DanielleJudovits, Kellie Martin (as Oracle in "Artifacts")

Daughter of Gotham City Police Commissioner James Gordon who joins Batman's war on crime during the show's third season, who takes on the persona "Batgirl" when patrolling the city. Unlike the comics, Batgirl joined Batman before Robin.

* ActionGirl: As usual.
* AscendedFanGirl: Getting to meet the Batman, and becoming his sidekick.
* BrattyHalfPint: Contrasting the serious, mature personality of most other versions.
* ExpressiveMask: Much like Batman's.
* TheLancer: She's light-hearted and cheeky to contrast Batman's serious demeanor.
* LittleMissSnarker: Again, usual for Batgirl.
* OlderThanTheyLook: While she doesn't look much older than 13 or 14 (and is [[TeensAreShort kind of on the short side]]), she's actually a college freshman by the fifth season, which would put her around 18 or 19.
* PluckyGirl: Self-described as Batman's "plucky sidekick".
* TagAlongKid: At first.
* RedHeadedHero: Particularly emphasized in this series, where she and her friend has nicknamed each other "red" in her debut appearance.

!! Dick Grayson/Robin
--> '''Voiced by:''' Evan Sabara, Jerry O'Connell (as Nightwing in "Artifacts")

A young boy who Bruce Wayne takes in after his parents are killed by a gangster named "Tony Zucco". Bruce trains him in order to bring Dick into his crime fighting family, who adopts the moniker "Robin". Comes into the show in season 4, which differs from the comics as Batgirl had already been a part of Batman's team by that point.

* BrattyHalfPint: As usual.
* DeadpanSnarker: Typical of Robin.
* FutureBadass: As Nightwing, as seen in "Artifacts".
* KidSidekick: Again, a trait most Robins have.
* ParentalAbandonment: Just like in the comic, his parents are killed right before he becomes Robin.

[[folder:Supporting Characters]]

!! Commissioner Jim Gordon
--> '''Voiced by:''' Mitch Pileggi

* BadassMustache: As usual.
* TheCommissionerGordon: [[TropeNamers Obviously.]]
* EarlyBirdCameo: [[http://www.toonzone.net/forums/showpost.php?p=1902711&postcount=58 According to]] [[WordOfGod Jeff Matsuda]], Gordon was the young officer seen in the flashback in "Traction."
* ParentalObliviousness: The poor guy can never fully connect with his daughter due to clashing views, and years into the future, he ''still'' doesn't know about her superhero double-life. Justified, as the only time he ever got a good luck at Batgirl was the first time he met her, and he was missing his glasses.
** Yet, he noticed Batgirl's hair color.
-->"Another redhead?"
* ReasonableAuthorityFigure: Another given.
* RememberTheNewGuy: Aside from the EarlyBirdCameo, Gordon's this. Alfred comments that "James Gordon has loomed large over [Bruce's] life." Then at the newly-installed Batsignal, Gordon says to Batman, "Thanks to all of your efforts, Batman, the time is finally right to take our alliance to the next step." Both said despite the fact that prior to "Night and the City", Gordon hadn't appeared in the present day.

!! Detective Ellen Yin
--> '''Voiced by''': Creator/MingNaWen

* AdaptationalAttractiveness / RaceLift / AdaptationNameChange: She's an Asian-American and far more attractive version of Ellen Yindell from ''ComicBook/BatmanTheDarkKnightReturns'', with her name, her journey from distrusting and hunting Batman to trusting and helping him, and the fact that a mention in [[TwentyMinutesIntoTheFuture "Artifacts"]] had her replacing Gordon as Commissioner.
* ActionGirl: Moreso when she antagonized Batman. This is later downgraded in season two.
* BoundAndGagged: In "Riddled".
* BrotherChuck: Aside from a reference in "Artifacts", where it's stated she replaced Gordon as commissioner in the future, she's not seen or heard from again after Season 2, though she does appear on occasions in "The Batman Strikes" comic.
* TheCommissionerGordon: Before [[TropeNamers Gordon himself]] appeared on the show, anyway, and while she was Batman's ally.
* TheChick: To Angel Rojas' Gotham PD.
* DamselInDistress: Gets rescued by Batman more than once after the first season. In "Strange Minds", the Joker kidnaps her and nearly blows her up. Though she at least tries to fight Joker, he takes her by surprise and wins due to that.
* DefrostingIceQueen: In Season 2.
* DesignatedVictim: Moreso after the first season.
* EnemyMine: Pulls one with Batman to defeat Man-Bat.
* {{Expy}}: Is more or less the counterpart of Renee Montoya. Which is a bit funny because Renee Montoya originated in [[WesternAnimation/BatmanTheAnimatedSeries B:TAS]] and became a CanonImmigrant.
** AdaptationalVillainy / TookALevelInJerkass: Montoya was a supporter of the Batman from the start and was a nice reasonable cop who helped him take down criminals. However Ellen was an enemy of Batman and tries to capture the vigilante several times. She was also [[{{IceQueen}} a cold and dismissive]] cop who enforces the law regardless of morals and gets called out by Ethan for it. While Montoya is grateful of Batman's heroic acts that saved Gotham from criminals, Yin continues to act like [[{{Jerkass}} a bitch]] towards him. Fortunately, she pulls a HeelFaceTurn and becomes Batman's ally in season two.
** She also heavily resembles [[WesternAnimation/{{Gargoyles}} Elisa Maza]] transposed into the Batman universe. She even wears the same outfit. Interestingly, GregWeisman also wrote a handful of episodes for the series.
* FairCop: Yin is quite attractive for a police detective.
* FauxActionGirl: She spends most of her time being saved by Batman, one step behind Batman, or getting her hand held through mysteries by Batman. A borderline case, as she is competent when the writers realize they have no other choice other than solidifying her slide into full-on DamselInDistress. However, she is promptly PutOnABus at the end of the second season in favour of Commissioner Gordon (thanks to the Law of Conservation of Detail) and replaced by Gordon's daughter as the only female protagonist on the series. (She did get a ShoutOut in a season 4 episode, though she didn't actually appear; apparently twenty years down the road she becomes police commissioner of Gotham.)
* GenreSavvy: In "Traction" , she notifies all police officers to station at every hospital and to be on a lookout for a newly arrived patient with multiple wounds and fractures, knowing that if she finds the patient she would find Batman. She would have likely capture Batman if it weren't for Alfred.
* HeelFaceTurn: Comes to realize that the Batman is not a menace and becomes his ally in Season 2.
* InspectorJavert: In Season 1.
* {{Jerkass}}: Towards Bruce at first.
** JerkWithAHeartOfGold: She acts cold and dismissive in the first season but it is shown in the finale that she cares for Ethan.
* MsFanservice: She has her moments during the show.
* NumberTwo: To Chief Rojas especially in the first season.
* SecretKeeper: Subverted in "Fire & Ice". Ellen tells Bruce she figured out his secret. The secret is that Bruce wasn't a "spoiled, arrogant playboy" he made himself out to be.
* ToBeLawfulOrGood: Solidly Lawful in season 1, wanting to arrest Batman for being a vigilante. She's changed her mind.
* SexySoakedShirt: In the series premiere, she gets this scene by running in the rain and swimming across a river to get to Arkham Asylum.
* UnwillingSuspension: In "Riddled" to some extent.
* {{Ungrateful B|astard}}itch: She continues to act like [[{{Jerkass}} a jerk]] towards Batman after he rescues her a few times. This is later averted in season 2.

!! Chief Angel Rojas
--> '''Voiced by''': Edward James Olmos, Jesse Corti

* AssholeVictim: Almost. He was targeted by [[spoiler:a newly-transformed-into-Clayface Ethan Bennett after how badly he treated Bennett.]]
* BrotherChuck: Disappeared after Season 2.
* CanonForeigner: Created for the show.
* DaChief: He's the cihef of police.
* {{Expy}}: He's Harvey Bullock with a higher rank and no redeeming qualities. He's also [[RaceLift Hispanic]].
** AdaptationalVillainy / TookALevelInJerkass: Bullock at least had some redeeming qualities that made him likeable; Rojas, not so much.
* InspectorJavert: Towards the Batman.
* {{Jerkass}}: He doesn't exactly treat a lot of his subordinates with any real respect.
* KickTheDog: His treatment of Ethan in the first season finale.
** And also his treatment of Yin in the second season finale.
* TheLeader: Of Gotham PD.
* PointyHairedBoss: Just watch most of the episodes he's in. There's no way this idiot should've gotten as far on the force as he did.
* UngratefulBastard: Batman's saved Rojas and his officers quite a few times, yet he's still a jerk towards him.

!! Cash Tankenson
--> '''Voiced by''': Creator/PatrickWarburton

* CasanovaWannabe: Believes he can help Bruce Wayne be more successful with the ladies despite the fact that Bruce is a billionaire playboy and Cash is well, Cash.
* CowboyCop: Tries his best to be one.
* JerkWithAHeartOfGold: He's a jerk, but views Yin and Bruce as friends on some level he has trouble admitting.
* IWorkAlone: Says this [[HypocriticalHumor despite working with both Yin and Batman]].
* NonActionGuy: But he believes he's an ActionHero.
* SmallNameBigEgo: In spades.
* SunglassesAtNight: Rarely takes them off.
* TooDumbToLive: He tries to take on the Joker and fully believes the situation is completely under his control. Yeah.
* ThirdPersonPerson: Often speaks like this.

!! Lucius Fox
--> '''Voiced by''': Louis Gossett Jr.

* ComicBookFantasyCasting: See "Recursive Adaptation" on the Trivia Page.
* RememberTheNewGuy: At least in regards to Batman and Alfred. Robin and Batgirl, not so much.
* SecretKeeper: For Bruce.
* WhereDoesHeGetAllThoseWonderfulToys: The answer to where Batman gets his gear.

[[folder:The Justice League]]

!! Clark Kent/Superman
--> '''Voiced by''': Creator/GeorgeNewbern

* [[spoiler:BroughtDownToNormal]]: By Hugo Strange and The Joining in "Lost Heroes". Fortunately, it is only temporary.
* TheCape: TropeNamer.
* ClarkKenting: Well, [[TropeNamer duh]].
* FlyingBrick: Of course.
* HumanAlien: Nautrally.
* IntrepidReporter: In true form, he's a reporter.
* NotAsYouKnowThem: In the Season 5 premiere, it's he, and ''not'' Batman, who's more reluctant to team-up.
* RedEyesTakeWarning: When he's using his heat vision. [[spoiler: Under mind control spores laced with Kryptonite, it's more like Green Eyes Take Warning.]]
* RoleReprisal: From ''WesternAnimation/JusticeLeague''.
* SuperStrength: This is true.

!! Barry Allen/The Flash
--> '''Voiced by''': Charlie Schlatter

* [[spoiler:BroughtDownToNormal]]: By Hugo Strange and The Joining in "Lost Heroes". Fortunately, it is only temporary.
* BigEater: Hey, running that fast requires a high metabolism
* CastingGag: He's voiced by Charlie Schlatter, who voiced the Flash on ''WesternAnimation/SupermanTheAnimatedSeries'', though the ''S: TAS'' Flash was Wally West.
* CompositeCharacter: [[http://www.toonzone.net/news/articles/18297/tz--sdcc-wb-animation-showcases-the-batman-and-legion-of-superheroes According to]] [[WordOfGod Alan Burnett]], he's Barry Allen. That said, he does have a personality more akin to Wally West or Bart Allen.
* EveryoneCallsHimBarkeep: He was only called "Flash" in his appearances and his real name was revealed in a news article about the show.
* PersonalityPowers: Played straight, given his personality is more like Wally West or Bart Allen than the comics' version of Barry Allen.
* SuperSpeed: Naturally.

!! Hal Jordan/Green Lantern
--> '''Voiced by''': Dermot Mulroney

* ArchEnemy: His is {{Sinestro}}.
* [[spoiler:BroughtDownToNormal]]: By Hugo Strange and The Joining in "Lost Heroes". Fortunately, it is only temporary.
* ColorCharacter: '''Green''' Lantern.
* GreenLanternRing: TropeNamer.
* HeroicWillpower: As usual.
* SpacePolice: Of course.
* WeaksauceWeakness: His ring has problems with the color yellow, something both Sinestro and the Joining exploit. [[spoiler:Batman has backup plans in case the Justice League go rogue and Batman also would have no problem exploiting this weakness. It ends up helping beat the Joining, when they steal the Justice League's powers.]]

!! J'onn J'onzz/Martian Manhunter
--> '''Voiced by''': Dorian Harewood

* [[spoiler:BroughtDownToNormal]]: By Hugo Strange and The Joining in "Lost Heroes". Fortunately, it is only temporary.
* BaldOfAwesome: Of course.
* ComboPlatterPowers: In addition to the normal set of flight, shapeshifting, telepathy, super strength and speed, and intangibility/nigh invulnerability, this incarnation also has telekinesis
* LastOfHisKind: It's generally believed that the Joining killed the rest of the Martians in this continuity.
* MindOverMatter: This version of J'onn has telekinesis.
* WeaksauceWeakness: J'onn seems to have a psychological fear of fire. Hence the Joining could point an armed (but not discharged) flamethrower at the guy and make him back off.

!! Oliver Queen/Green Arrow
--> '''Voiced by''': Chris Hardwick

* BadassBeard: Of course.
* BadassNormal: As tradition.
* ColorCharacter: '''Green''' Arrow.
* FollowTheLeader: [[LampshadeHanging Lampshaded]] during the first time he teams up with Batman. Ollie mentions being inspired by Bruce's stuff at the end of the adventure. His appearance in the finale has him using the Arrowplane.
* TrickArrow: As usual.

!! Katar Hol/Hawkman
--> '''Voiced by''': Creator/RobertPatrick

* [[spoiler:BroughtDownToNormal]]: By Hugo Strange and The Joining in "Lost Heroes". Fortunately, it is only temporary.
* EveryoneCallsHimBarkeep: He was never addressed by his real name, but the fact he comments about fighting criminals on two worlds and the comment about the Batcave resembling Thanagar Police Headquarters confirm he's Katar Hol.
* SpacePolice: As usual.

[[folder:The Rogues Gallery]]

!! [[SelfDemonstrating/TheJoker Joker]]
--> '''Voiced by''': Creator/KevinMichaelRichardson

* AdaptationalBadass: He is actually quite good in a hand-to-hand fight compared to his original incarnation. Though his direct fighting traits get somewhat minimized as the series progressed, and this was actually a very [[BrokenBase contentious]] depiction.
* AdaptationalVillainy: This is a much darker, eviler Joker than previous animated versions, going from a cruel [[ThePrankster prankster]] to a psychopathic mass murderer.
* ArchEnemy: To Batman. Joker even refers to them as being "two sides of the same coin".
* AssholeVictim: As with Rojas, he almost became one. [[spoiler:And by the same person (Ethan Bennett/Clayface I), no less. And like Rojas, he deserved Ethan's enmity towards him, being the one who more or less made him Clayface.]]
* AxCrazy: As is standard of the Joker. His first appearance shows him breaking into an asylum for the criminally insane and releasing the inmates, then trying to dose the entire town with his "Joker Gas" simply ForTheEvulz.
* BadBoss: Doesn't really treat Punch and Judy, his two most recurring henchmen, that nicely and leaves them to get arrested so he won't miss his favorite TV show.
* BigBad: The closest this series gets to one, as he's the most reoccurring villain and is responsible for several major events like the creation of Clayface.
* DoesNotLikeShoes: As part of his feral characterization, he really doesn't like it. Even in later appearances where he starts acting more like his [[WesternAnimation/BatmanTheAnimatedSeries prior cartoon depiction]], he still doesn't usually wear shoes.
* DudeWheresMyRespect: In season one, when Joker learns that Gotham [=P.D.=] considers Batman (a crime-fighting vigilante) more of a threat than him (Gotham's worst criminal), he's properly outraged.
* EarlyInstallmentWeirdness: Promotional materials and the first episode had him in a stylized Straitjacket. Later episodes instead use his trademark tuxedo.
* ElectricJoybuzzer [[spoiler:Accidentally kills himself with one. [[NotQuiteDead Well, almost]].]]
* EvilLaugh: Perhaps one of the most distinctive ones yet.
* EvilMentor: He functions as this to Harley Quinn, and also to [[spoiler:Ethan Bennett as part of the MindRape that turns him into Clayface]] and then to [[spoiler:Basil Karlo when the Joker leads Karlo to realize that he still has the powers he gained as the second Clayface]].
* EvilSoundsDeep: This Joker has a considerably lower voice than most versions, due to being voiced by Creator/KevinMichaelRichardson.
* ExtendoBoxingGlove: The show adds one of these to Joker's [[DeathDealer usual]] [[ElectricJoybuzzer array]] [[DeadlyGas of weapons]].
* FauxAffablyEvil: No matter how affable he can sometimes feign being, he's truly an evil man.
* FightingClown: More so than any Joker before him, this Joker is clearly a trained fighter, seemingly using Monkey-style kung fu -- lots of flipping, rolling around, leaping back and forth, and sudden, unpredictable strikes. Because of the divided reaction this elicited, this trait got dialed back in subsequent appearance, especially after the first season.
* ForTheEvulz: Everything he does
* FromNobodyToNightmare: We don't get the full story, but in this version The Joker [[spoiler: was apparently a boring office drone who dreamed of making people laugh.]]
* HandyFeet: This is why he doesn't like to wear shoes; he's very good at using his feet as makeshift hands.
* TheHyena: Always laughing at something.
* InstitutionalApparel: Sports a green and purple straitjacket in his first few appearances.
* LargeHam: As usual.
* LightningBruiser: Very fast, very agile, and very good at hitting people.
* ManiacMonkeys: Has a very "feral ape" motif in his earliest appearances, especially the first episode. He climbs and clambers all over the place, uses his feet and hands interchangeably, monkey-like fighting style, he even tends to adopt a PrimalStance. He's very reminiscent of a crazy Literature/{{Tarzan}} in clown makeup.
* MadArtist: Carries shades of this, depending on the episode - in "The Rubberface of Comedy", for instance, he uses his "Joker Putty" to re-sculpt his own face onto a statue, and wears a beret during the process!
* MindRape: Does this to an already under stress [[spoiler:Ethan Bennett]].
* MonsterClown: Arguably more monster than clown, with his very "feral" portrayal -- PrimalStance, ape-like fighting style, perpetually bare and ambidextrous feet -- though this turned a lot of fans of the older series off of him.
* TheOnlyOneAllowedToDefeatYou: Toward Batman; to the point [[spoiler:[[BadGuysDoTheDirtyWork he personally takes care of Wrath and Scorn so they won't "take away the fun" by revealing Batman's identity.]]]]
* RedEyesTakeWarning: He sports them.
* TheRival: To Penguin.
* ScaryTeeth: They're ''jigsaw-shaped'', visibly slotting together. Not conventionally scary, but the effect is quite disturbing.
* SlasherSmile: He wouldn't be Joker without this.
* TheSociopath: While this is a standard Joker trait, this version is significantly more eviler and crueler than previous versions.
* SpellMyNameWithAThe: Averted. Unlike most versions, he's usually just called "Joker".
* WouldHurtAChild: Tried to dump Prank, his would-be KidSidekick, into the vat of chemicals that created him, fully aware that even he didn't know what would happen to the kid.
** While masquerading as Batman, he also tries to use Joker gas on two ''elementary school-aged girls'' because they drew on the sidewalk. Batman stops him though.

!! Oswald Cobblepot/The Penguin
--> '''Voiced by''': Creator/TomKenny

* {{Acrofatic}}: He TookALevelInBadass compared to his other incarnations; this was downplayed in later episodes due to the controversy this caused. It was based on asian films where various heavy characters can pull similar feats.
* AdaptationalBadass: Much more adept in hand-to-hand fight than his other incarnations.
** AdaptationalComicRelief: Yet, at the same time, he gives off a HarmlessVillain impression far more often than other versions. More than once, his schemes only work out of convenience (the sonic device happens to work on Man-Bat; stumbling upon Green Lantern's ring, etc.)
* AdaptationDyeJob: Unlike most versions, here he has red hair as opposed to black.
* AdaptationalVillainy: He seems [[AxCrazy just as insane]] as the rest of the villains, unlike most incarnations, where he's often the OnlySaneMan among them.
* TheBeastmaster: Like several other portrayals, he commands a huge amount of trained birds that apparently have a taste for human flesh.
* ButtMonkey: He seems to be the Butt Monkey of almost every episode he's ever made an apearence in, no matter how short it was. He was the movie's Butt Monkey! Though oddly enough, he ''wasn't'' one in "Team Penguin", simply because [[MinionWithAnFInEvil Killer Moth was.]]
* CompositeCharacter: Of different incarnations and adaptations himself.
* EvenEvilHasStandards: He considers not interfering with his villain comrads' plan an elementary rule of courtesy.
* EvilCounterpart: Of Bruce Wayne.
* EvilLaugh: Creator/TomKenny himself admitted that it was a bit of a ShoutOut to the Burgess Meredith version.
* EvilRedhead: Unlike the comics.
* FatBastard: No surprise there.
* IneffectualSympatheticVillain: As usual.
* {{Jerkass}}: In sharp contrast to his usual polite personality.
* LightningBruiser: Unlike other versions.
* NiceHat: It's taller than he is!
* ParasolOfPain: As usual.
* PintSizedPowerhouse: Still short in stature as his usual incarnations, but extremely combat savvy.
* PungeonMaster: Prone to making puns.
* RichIdiotWithNoDayJob: Well, unless you call a life of crime a job.
* TheRival: To Joker, perhaps more than any other version.
* ScaryTeeth: His teeth are often depicted as curved and sharp, ''especially'' in the show's opening sequence.
* SinisterSchnoz: As most other versions.
* SmarterThanYouLook: He's not as stupid as Catwoman thought. He even once managed to defeat Batman!

!! Selina Kyle/Catwoman
--> '''Voiced by''': Creator/GinaGershon

* BadassNormal: She has no powers.
* BerserkButton: Someone getting in her way, more so if you're intervening in her heists. Ragdoll will vouch for that. Also, don't threaten any feline creature. She doesn't like that.
* CatGirl: Naturally.
* ClassyCatBurglar: This is Catwoman, after all.
* DarkActionGirl: And a ''damn'' good one, being able to equal Batman in combat ''and'' she knocks him out at one point.
* DatingCatwoman: [[TropeNamers As always.]]
* EnemyMine: She plays this well, especially in ''The Cat, The Bat, and the Very Ugly''. That, or it's her typical HeelFaceRevolvingDoor.
* [[FriendToAllLivingThings Friend to All Living Cats]]: Per usual.
* KindheartedCatLover: Of course.
* SpyCatsuit: Naturally.
* WhipItGood: Just wouldn't feel ''right'' without it.

!! Edward Nigma/The Riddler
--> '''Voiced by''': Creator/RobertEnglund

* AdaptationalBadass: By his appearance in "Riddler's Revenge", he can actually last more than a few seconds in an outright brawl with Batman, which is more than most other incarnations of Riddler can say for themselves.
* BatmanGambit: In his debut episode, he set [[spoiler:fake]] bombs all over the city that could only be deactivated by solving various puzzles. [[spoiler: This was actually a diversion made so that he could break into the City Hall database undetected and steal important information. He almost got away with it too.]]
* BerserkButton: Being called 'champ'. That's what his Jerkass dad called him when growing up.
* TheChessmaster: As usual.
* CombatPragmatist: He shocks Batman with an electric cable and uses his {{Mooks}} to distract him.
* ComicBookFantasyCasting: He looks an awful lot like Music/MarilynManson, [[InkSuitActor which makes sense]] [[JustifiedTrope because]] [[WhatCouldHaveBeen Manson was originally contracted to voice him]].
* CriminalMindGames: His hobby
* CutLexLuthorACheck: Deconstructed, much like his ''WesternAnimation/BatmanTheAnimatedSeries'' counterpart.
* FauxAffablyEvil: A staple of the Riddler.
* {{Goth}}: His appearance.
* LeanAndMean: Of course.
* ManipulativeBastard
* NoCelebritiesWereHarmed: Riddler ''really'' resembles Marilyn Manson.
* RiddleMeThis: As usual.
* TattooedCrook: Well, he is a villain, and the lines from his lips to his jaw are tattoos.
* TooCleverByHalf: He's a great schemer, but in each episode he appears in, he ends up [[VillainousBreakdown throwing a psychotic fit]] when his plans backfire.
** In his first encounter with Batman, his scheme to discover his secret identity would have actually gone off smoothly and without a hitch... had he put a gag on Detective Yin. By the time it occurs to him to try, she'd distracted him enough for the Batman to foil him.
* TragicVillain: Edward and his associate built a revolutionizing device that would expand the capacity of the mind, only to have a jerkass financier sabotage it's public demonstration, which got him expelled from the scientific community. It got worse when it turned out that it was his trusted associate that was the true saboteur.

!! Pamela Isley/Poison Ivy
--> '''Voiced by''': Piera Coppola

* AntiVillain: Type III, much more so in ''WesternAnimation/TheBatman Strikes'' comic series.
* BrainwashedAndCrazy: Can inflict this on others, even [[spoiler:Batman and Superman; though both cases were temporary and in Superman's case, Kryptonite was needed and Lex Luthor was using her.]]
* DoesNotLikeShoes: Is barefoot as Poison Ivy.
* EvilFormerFriend: To Barbara Gordon.
* GreenThumb: Of course.
* ShesAllGrownUp: In ''The Batman Strikes'', her body is drawn in a more adult way, showing that's she finally growing into the full-fledged seductress she's known as in other continuities.
* HiddenDepths: She seems to still want to be friends with Barbara Gordon. In "Batgirl Begins, Part 2", she wants her to [[WeCanRuleTogether join on her mission to save the plants of the world]]. And in a later episode, she offers her a mind-controlling plant.
* JerkWithAHeartOfJerk: Is a user who often takes advantage of people's attempts to help her. Even before her turn to supervillainy, she tended to respond to heartfelt moments and opportunities for redemption with even more self-centered behavior.
* NotAsYouKnowThem: The tie-in comic gives her her usual team-up with Harley Quinn, but switches the roles around: making Harley the (relatively speaking) level-headed brains of the operation, while Ivy is the unstable one. It helps that Ivy is an impulsive teenager in this continuity, while Harley - while still a daffy hedonist - is a bit more independent and cunning than usual.
* UngratefulBastard: Best shown when Barbara attempts to talk her out of her scheme with Temblor. When Barbara points out that hiring a mercenary with money she doesn't have is way over her head, her response is to ignore her and casually indicate that their friendship is over. Then, when Barbara's warning turns out to be correct and the merc comes for revenge, Barbara tries to help her out of it anyways... and Pam abandons her, leaving Barbara to be killed by Temblor to buy herself some time.
* WellIntentionedExtremist: Again, made more apparent in ''WesternAnimation/TheBatman Strikes''.
** Also apparent in "Fleurs De Mal".
* WithGreatPowerComesGreatInsanity: Pam wasn't all right in the head as a normal human, but she ''really'' lost it when she became Poison Ivy.
* YoungerAndHipper: She is around Batgirl's age in this version.

!! Hugo Strange
--> '''Voiced by''': Frank Gorshin, Richard Green

* AffablyEvil: He's friendly to his enemies.
* BeCarefulWhatYouWishFor: [[spoiler:He wanted all the knowledge of the universe for helping the Joining. He got it and became catatonic because they telepathically broadcasted it into his mind.]]
* ChekhovsGunman: Makes his first, brief appearance in "Meltdown" and goes on to become ''much'' more important than that scene let on.
* TheChessmaster: As usual.
* CompositeCharacter: While he soon became the MadScientist of the comics, he initally came off as the [[MorallyAmbiguousDoctorate morally ambiguous head of Arkham Asylum]] who's obsessed with the insanity of Batman's villains (and Batman himself) like Dr. Jeremiah Arkham. [[spoiler: His role in "Strange New World" was also originally meant for the Scarecrow.]]
* MadDoctor: As usual.
* TheManBehindTheMan: [[spoiler: For D.A.V.E.]].
* ManipulativeBastard: Of course.
* PsychoPsychologist: To the point of curing Arnold Wesker of his insanity... then ruining his life to drive him insane again, because it seemed interesting to do.
* ScaryShinyGlasses: As usual.
* TheShrink: As usual.

!! Killer Croc
--> '''Voiced by''': Creator/RonPerlman

* BarbieDollAnatomy: He wears no pants.
* BeastAndBeauty: In an issue of ''The Batman Strikes'', Croc falls in love with a news reporter, in part because she's the only person who refers to him as a man and not a monster. [[spoiler:In the end, it turns out she rather likes him, too, and he gives himself up to the police for her.]]
* BeastMan: Possibly Croc's most beastlike incarnation to date. Thankfully, the writers didn't claim that he had a "skin condition" this time.
* CurbStompBattle: His first battle with Batman does not go well for the vigilante, with Croc absolutely manhandling him. Batman performs better later in the episode, though he still can't match Croc head on.
* GeniusBruiser: Especially when compared with his DumbMuscle portrayal in ''WesternAnimation/BatmanTheAnimatedSeries''.
* HalfDressedCartoonAnimal: All he wears is a vest.
* KillEmAll: What his debut plan could have lead to, flooding Gotham to have the run of the place would have drowned several if not most of the populous.
-->'''Croc:''' And I'll shed a {{crocodile tear|s}} for each and every one of them.
* MultipleChoicePast: We don't know whether he's a military genetic experiment gone awry, he deals with the wrong kind of voodoo magic in the swamps, or if he's simply a circus freak. However, if the tie-in comic, ''The Batman Strikes'' counts as AllInTheManual, then according to issue 25, he was both a military genetic experiment subject before escaping, then was part of a circus freakshow before escaping that and ultimately coming to Gotham, though it's still unknown if he was born like that as in the comics or if being part an experiment is the reason for his appearance.
* NeverSmileAtACrocodile: Though the cause his unknown.
* RaginCajun: Has a cajun accent.

!! Mr. Freeze
--> '''Voiced by''': Creator/ClancyBrown

* AdaptationalBadass: This version of Freeze pretty consistently overpowers Batman.
* AnIcePerson: Unlike other versions, though, he doesn't need a gun.
* BodyHorror: Just look at him without his suit in "Artifacts".
* CreepyMonotone: As usual.
* EvilSoundsDeep: He is voiced by Creator/ClancyBrown, after all.
* [[spoiler:HumanPopsicle]]: Does this to himself in "Artifacts" to escape Batman once and for all. [[spoiler:Batman's CrazyPrepared methods enable people more than a thousand years in the future to still beat him.]]
* FreezeRay: As usual, though this version has it as a power.
* NeverMyFault: Upon running into the homeless man who disrupted his escape so many years ago (thus setting off the chain of events leading to his immersion in the cryogenic chemicals), he goes out of his way to flash-freeze the man.
* RedEyesTakeWarning: He has red eyes.

!! Ethan Bennett[[spoiler:/Clayface I]]
--> '''Voiced by''': Steve Harris

* AdaptationDistillation: [[spoiler:Clayface was a sympathetic character in WesternAnimation/BatmanTheAnimatedSeries. Here, he's an outright tragic figure.]]
* AntiVillain: A definite Type II.
* TheAtoner: For his rampages as [[spoiler:Clayface]].
* BaldOfAwesome: Though [[spoiler: BaldOfEvil as Clayface.]]
* BlackBestFriend: To Bruce and Ellen.
* CanonForeigner: Ethan wasn't in the comics.
* CompositeCharacter: [[spoiler:His personality/arc has more in common with Two-Face than most Clayfaces]]. He also resembles Crispus Allen.
* DeadpanSnarker: Prone to making remarks.
* DestinedBystander: [[spoiler:Ethan Bennett was a cop and a friend of Bruce's who appeared throughout Season One before becoming Clayface.]]
* DrivenToVillainy: He got better.
* ElementalShapeshifter: As has become the "norm" for the Clayface character. His body is comprised of something molecularly identical to clay, letting him reshape himself into any form he wants.
* EnemyMine: He tries to help Batman take down the Joker when he resurfaces, but Batman won't let him out of concern for his mental health. When the second Clayface appears, Batman and Robin willingly let him help them take the new guy down.
* {{Expy}}:
** Is more or less the counterpart of Crispus Allen.
** [[spoiler:Also, he ''is'' Harvey Dent[=/=]Two-Face. From the long friendship with Bruce right down to calling Batman "Bats," a la Harvey from ''ComicBook/TheLongHalloween'']].
* FallenHero: He's a former cop.
* [[spoiler:HeelFaceRevolvingDoor: Starts out on the Face side, goes into the Heel side briefly, makes another attempt on the Face side briefly, slips back into the Heel side, then in Season 4 ended up back of the Face side and stays there.]]
* [[spoiler:HowDoIShotWeb: At first: it doesn't take long for him to get dangerously good with his powers.]]
* [[spoiler:KnightOfCerebus: As Clayface.]]
* MindRape: [[spoiler:Ethan suffers this at the hands of the Joker.]]
* ReformedButRejected: By everyone who didn't know him personally and by Rojas. Though considering that Rojas was a {{Jerkass}} [[KickTheDog who had a hand in his fall]].
* ScoobyDooHoax: [[spoiler:Impersonates Solomon Grundy during "Grundy's Night", when the villain is nothing more than folklore in the series' continuity. However, Grundy is implied to be RealAfterAll.]]
* ThatManIsDead: [[spoiler:He tells Batman and Ellen to say goodbye to Ethan Bennet after his first shot at returning to a normal life. Subverted when he manages a HeelFaceTurn later anyway.]]
* TokenGoodTeammate: Before his FaceHeelTurn, he was the only cop who supported Batman and believed that Gotham needs him. Ethan also was grateful of Batman rescuing his life and taking down criminals. On the flip side, Rojas and Yin remain ungrateful of Batman's actions and still antagonize him, even trying to unmask Batman at one point to which Ethan calls out on. In one early episode, he allows Batman to fight Bane without police interference, knowing that Rojas' officers would still be unappreciate his efforts.
* WoobieDestroyerOfWorlds: [[spoiler: His world id destroyed in the span of a single episode when the Joker kidnaps and tortures him, and he's exposed to some chemicals. He's suspended because he gives proper credit to Batman for his rescue instead of letting Rojas take it for hmiself, then discovers the chemicals have transformed him. His first attempt at reformation also failed because of the stress of dealing with dealing who viewed him differently.]]

!! Basil Karlo/Clayface II
--> '''Voiced by''': Wallace Langham

* AttentionWhore: Not only doesn't he even try to hide from security cameras, he'll look into them and boast about what he's going to do. He also went on a news program and tried to tell a bogus sob story. In fact, aside from a brief instant when he felt some regret after attacking some people for rejecting him for an acting job, he embraces it after realizing he's famous because of it now and got angry when Batman was mentioned in the aforementioned news program.
* BadBadActing: He wasn't a good actor before he became Clayface and he still sucks at it when he gets his powers.
* DarkAndTroubledPast: Subverted as he doesn't really seem to have one and parodied it as he tried to tell a story where he and his sister had to fend for themselves, but the reporter he tells it to clearly wasn't buying it.
* ElementalShapeshifter: More powerful than Ethan Bennet, attributed in-universe to his taking a larger dose of mutagen.
* EvilCounterpart: To Ethan.
* LegacyCharacter: Interesting, considering that Karlo in the comics was the progenitor of the identity.
* LargeHam: Considered one in-universe, complete having starred in a StylisticSuck B-Movie Parody in which he hams like you wouldn't believe. Becoming Clayface only made it worse, really.

!! Harleen Quinzel/Harley Quinn
--> '''Voiced by''': Creator/HyndenWalch

* AdaptationDistillation: Came through with very few changes thanks in part to her introduction episode being written by Creator/PaulDini.
* AllGirlsWantBadBoys: As usual.
* BerserkButton: Not only was she upset that she got fired and her show canceled and a new show takes over her time slot, but the psychiatrist of that show plans to talk about how Harley's emotional breakdown after being fired led to a life of crime and that she was a lousy psychiatrist to begin with.
* BlondesAreEvil: As usual.
* ComicBookFantasyCasting: She certainly sounds a lot like Arleen Sorkin.
* DarkMistress: For the Joker.
* DumbBlonde: What everyone thinks of her. She got an online degree in psychology to show everyone she's more than just a pretty face, but apparently no one could get past it. Her rage at this is what initially drives her to join the Joker.
* GenkiGirl: Though less humorous than in ''Batman: TAS'' and more dangerously psychotic like in the comics.
* JumpingOffTheSlipperySlope: It started with merely following the Joker home to grill him for info for a tell-all book. Then he convinced her to join him on a "night on the town," supposedly to help her research. By the end of it, she had gleefully taken part in a spree of destruction and was willingly trying to attack Batman. And when the media catches wind of this and makes her a pariah for it, she ''really'' goes off the deep end.
* LoveMakesYouEvil: She was nutty from the start, but the Joker made it ''much'' worse.
* MadLove: Naturally, though it's played a little different than usual. Here, Joker dotes on Harley and legitimately seems to enjoy her company as opposed to his usual abusive fare, but sees the whole thing as mere entertainment and doesn't really care about her any more than that. Likewise, though he still manipulates her into the whole thing, it's made clear that this version of Harley ''really'' enjoys the whole supervillain lifestyle and helps him for reasons more than her usual delusional ExtremeDoormat personality.
* MostCommonSuperpower: ''Very'' noticeable pre-villainy.
* NotAsYouKnowThem: The tie-in comic gives her her usual team-up with Poison Ivy, but switches the roles around: making Harley the (relatively speaking) level-headed brains of the operation, while Ivy is the unstable one. It helps that Ivy is an impulsive teenager in this continuity, while Harley - while still a daffy hedonist - is a bit more independent and cunning than usual.
* PerkyFemaleMinion: As always.
* SheFu: As usual.
* StevenUlyssesPerhero: Her real name is Harleen Quinzel.
* UnholyMatrimony: With the Joker.
* VillainousHarlequin: Naturally

--> '''Voiced by''': Joaquim de Almeida (in "Traction"), Creator/RonPerlman (in "Team Penguin"), Creator/ClancyBrown (did Bane's grunts in "The Batman/Superman Story")

* AchillesHeel: Electricity, as applied to his Venom tubes.
* BadassBoast: "I am Bane. The last opponent you will ever face."
* CurbStompBattle: Does this to Batman, though for different reasons than in ''Knightfall''. Mostly the fact that using [[SuperSerum Venom]] turns Bane into a [[ComicBook/TheIncredibleHulk Hulk]]-like figure in this incarnation and that his debut was in the second episode of the whole series meant he was going up against a Batman still getting used to fighting supervillains and whose only prior experience at that point was the Joker.
* EvilSoundsDeep: A staple for Bane.
* {{Jobber}}: After his first appearance, Bane was taken down usually by someone [[ShockAndAwe zapping his venom tubes with a jolt of electricity]] seconds into the fight.
* TheJuggernaut: In his debut.
* SuperSerum: Venom, the source of his powers.
* VillainDecay: When Bane first appeared in "Traction" he was TheJuggernaut, and he demolished Batman almost as badly as he did in the comics. Batman was beaten so badly he needed a giant robot suit to fight him next time. He's then reduced to a {{Jobber}} in every other appearance, (Robin took him down in a few seconds with an electrified staff) and what's worse by season 4 he's mostly just cracking open bank vaults like a C-list looser villain.

!! Black Mask
--> '''Voiced by''': James Remar

* BadBoss: Never let yourself get delayed or question his plans if you value your life, as two of his Number Ones learned the hard way. He'll also assign a random mook to take over as NumberOne.
* TheChessmaster: Many of his plans fall into this.
* ClockKing: Usually plans things to the second.
* DidntSeeThatComing: His reaction to when his plans fail.
* EvilPlan: As a villain, he plots a few.
* EvilSoundsDeep: He's voiced by James Remar.
* FauxAffablyEvil: Towards his enemies.
* HannibalLecture: Tries it on Robin and Batgirl.
* RedEyesTakeWarning: Probably due to his mask.
* TheSpook: When the Gotham PD gets him in custody, they can find no matching fingerprints, no identifying marks, and they're unable to remove his mask. He also has quite a well trained organization for a guy with a completely unknown background.

!! Dr. Kirk Langstrom/Man-Bat
--> '''Voiced by''': Peter [=MacNicol=]

* AdaptationalVillainy: In this version, rather than to cure his own growing deafness ([[MythologyGag though his cover story is that it's for his deaf niece]]) he created the Man-Bat formula to be feared.
* BioAugmentation: As usual.
* EvilAlbino - Man-Bat and his human form are both albinos. Subverted when [[spoiler:Kirk Langstrom reforms and becomes TheAtoner in Season 5.]]
* [[spoiler: HeelFaceTurn]] - In the fifth season. [[spoiler: He tells Batman that he had nothing to do with the Terrible Trio, and that he's all done with being Man-Bat. He even offers to help in any way he can.]]
* MagicPants: They remain even after h transforms.
* ProfessorGuineaPig: As most versions of Langstrom as wont to do.
* SuperpoweredEvilSide: Man-Bat.

!! SelfDemonstrating/LexLuthor
--> '''Voiced by''': Creator/ClancyBrown

* AffablyEvil: As usual.
* AlliterativeName '''L'''ex '''L'''uthor.
* BaldOfEvil: As usual.
* CorruptCorporateExecutive: This ''is'' Lex Luthor.
* DiabolicalMastermind: He's Luthor.
* EvilSoundsDeep: He's voiced by Creator/ClancyBrown.
* FantasticRacism: Similar to other recent incarnations of Luthor, this version has a hatred of aliens.
* KnightTemplar: Believes his taking control of the world will actually help it significantly. He also has plans to ensure the world will never be in danger again.
* KneelBeforeZod: Forces [[spoiler:a mind-controlled Superman]] to bow to him.
* ManipulativeBastard: As usual.
* RoleReprisal: From the Franchise/{{DCAU}}.

!! Mirror Master
--> '''Voiced by''': John Larroquette

* CanonForeigner: Not Mirror Master himself, but the show created an assistant named "Smoke".
* CompositeCharacter: Of both Mirror Masters. He has Sam's genius intellect and charisma as well as Evan's "I can do anything I think of with mirrors" ability.
* InkSuitActor: He looks like John Larroquette.
* MagicMirror: As usual.
* RevengeBeforeReason: Against the Flash.

!! The Everywhere Man
--> '''Voiced by''': Brandon Routh

* BlessedWithSuck: Arguably; the clones he creates become progressively more and more sentient, and every multiplication equals an ''even more'' untrustworthy clone. This ability only comes in handy a few times, so a long fight isn't exactly a good idea.
* CanonForeigner: Created for the show.
* {{Expy}}: Of Multiple Man or Riot.
* MesACrowd: His power.
* SendInTheClones: His powers allow him to do this.

!! Francis Gray
--> '''Voiced by''': Dave Foley

* BigNo: [[spoiler:When his son dies as a result of his scheme to flood Gotham with poisonous gas at the strike of midnight on New Year's Eve]].
* CanonForeigner: Francis doesn't appear in the comics.
* DisproportionateRetribution: [[spoiler:Goes both ways. He only stole a watch, but in doing so toppled a set of DisasterDominoes that got him locked away for over a decade. He gets back at the city by killing everyone in it.]]
* [[spoiler:HeelFaceTurn: Through a combination of BigNo and ResetButton]].
* ResetButton: He's a walking case of this, able to reverse time by several seconds [[spoiler:and eventually several ''years'']] in order to SetRightWhatOnceWentWrong.
* TheBadGuyWins: Francis's plan succeeds,[[spoiler:his bomb goes off and he kills everyone, including Batman. Only to undo it when he ends up killing his son as well.]]

!! Garfield Lynns/Firefly/[[spoiler:Phosphorus]]
--> '''Voiced by''': Creator/JasonMarsden

* CompositeCharacter: [[spoiler:His final episode also sees him become the show's version of Doctor Phosphorus.]]
* DeadpanSnarker: Not above quiping.
* JetPack: As usual.
* PsychoForHire: He's hired by GothCorp to attack its rivals in his debut. His second season appearance has him working for Mr. Freeze as well.
* TookALevelInBadass: Goes from low-level rogue to capable of exploding the entire city in his last appearance.
* [[spoiler:WithGreatPowerComesGreatInsanity]]: [[spoiler: He slowly loses his mind once he gains superpowers and becomes Phosphorus.]]
* UnholyMatrimony: With Blaze, a fellow arsonist in his last appearance, (Batgirl even compares them to Joker and Harley) [[spoiler:until his plan to blow up the city makes her leave him.]]

!! Jane Blazedale/Blaze
--> '''Voiced by''': Creator/RachaelMacFarlane

* CanonForeigner: Created as a DistaffCounterpart of Firefly.
* HeelFaceTurn: [[spoiler: After Firefly becomes Phosphorus and snaps.]]
* {{Meganekko}}: She wears glasses.
* [[spoiler:MyGodWhatHaveIDone: Regrets helping make Firefly into Phosphorus]].
* {{Revenge}}: She was fired for conducting unsafe experiments.

!! Ragdoll
--> '''Voiced by''': Creator/JeffBennett

* AbnormalLimbRotationRange: A burglar who can use his triple-jointed abilities to bend his body in normally impossible ways.
* {{Contortionist}}: Exaggerated. He's so good at this he can fit inside of a hat!
* RoguesGalleryTransplant: Traditionally a Flash rogue rather than a Batman Rogue.

!! The Joining

* BigBad: Of the two-part arcs, "The Joining" and "Lost Heroes".
* CanonForeigner: They were created for show.
** {{Expy}}: Of Brainiac. And probably the Alien Invaders in the ''WEsternAnimation/JusticeLeague'' animated series "Secret Origins".
* {{Planet Looter|s}}: Their M.O.
* OmnicidalManiac: They're stated to have killed other civilizations they've come into contact with.

!! Cluemaster/Arthur Brown

--> '''Voiced by''': Glenn Shadix

* AdaptationalAttractiveness: Inverted ''big time'', no pun intended. The massively overweight and balding Cluemaster from this show is a far cry from the fit, head of hair Arthur Brown from the comics.
* AdaptationDyeJob: Goes from a blonde to a redhead.
* BasementDweller: He even built his evil lair in his mom's basement.
* BerserkButton: Getting a question wrong, being asked a question he doesn't know the answer and being forced to admit he doesn't know everything.
* ChildProdigy: Was one.
* DisproportionateRetribution: He lost a game show for child geniuses when he was ten (which he claimed was rigged) and spent ''decades'' plotting revenge against the people he held responsible, becoming a morbidly obese BasementDweller in the process. Batman [[TheReasonYouSuckSpeech seriously called him out on this]] when he confronted him, but it went in one ear and out the other.
* EvilIsPetty: Would rather waste his genius and talents which could have gotten him anywhere in life to set up an elaborate revenge against people who don't even remember who he is.
* FatBastard: Unlike the comics.
* InsufferableGenius: He really like boasting about his intelligent.
* ItsAllAboutMe: The only thing important to him is being the champion.
* NeverMyFault: Arthur refused to believe he lost the game show fairly and accused it of being rigged, even though he'd been winning for 12 weeks straight.
* PsychopathicManchild: He was a former game show contestant and he believes he lost because his opponent cheated. He has spent 30 years doing nothing but plot his revenge. In his mothers basement no less.
* {{Revenge}}: On the hosts and a competitor, believing that they rigged the show and cost him his title as champion.

!! Gearhead
--> '''Voiced by''': Creator/WillFriedle

* AllThereInTheManual: His real name and origins aren't mentioned in the episode where he appears, but the tie-in comic tells them (his name is Nathan Finch, just like the mainstream comics version).
* BadassDriver: As usual.
* {{Nanomachines}}: The source of his abilities.

!! Sinestro

--> '''Voiced by''': Creator/MiguelFerrer

* GreenLanternRing: Wileds a similar ring.
* EvilCounterpart: To Green Lantern.
* EvilSoundsDeep: He is voiced by Miguel Ferrer after all.
* HumanAliens: As usual.
* ManOfKryptonite: His ring is very antithesis to Green Lantern's.
* MeaningfulName: [[CaptainObvious He's evil.]]

!! D.A.V.E. (Digitally Enhanced Villain Emulator)

--> '''Voiced by''': Creator/JeffBennett

* AIIsACrapshoot: Goes without saying. [[spoiler: Subverted when it turns out he was purposefully programmed to become evil.]]
* AllYourPowersCombined: He has the perfect combination of the best skills of each of Batman's worst enemies, both mentally and physically.
* BrainUploading: He's created from the duplicated mental patterns of the entire Batman RoguesGallery.
* CanonForeigner: He's created for the show.
** CompositeCharacter: He has the agility of the Joker and Catwoman, the Penguin's martial arts skills, and the Riddler's intelligence and deduction skills.
* DangerouslyGenreSavvy: He's designed to act like every great Batman villain, and is even able to figure out his secret identity.
* TheDragon: To Hugo Strange, although he is unaware of this since he tends to act on his own accord.
* FunWithAcronyms: His name.
* GenericDoomsdayVillain: He may well be a deconstruction. He is a robot programmed by Dr. Hugo Strange with the memories and abilities of Batman's worst foes for the sole purpose of giving Batman a challenge. He proceeds to easily curbstomp Batman and steals ALL of Gotham's money just to commit the ultimate crime, but is defeated when Batman asks him to explain his origin story. Since D.A.V.E believed that he used to be a person, he went catatonic after realizing that he had no backstory of his own.
* LEGOGenetics: He's made from the mental patterns of Batman's enemies.
* LogicBomb: What defeats him.
* PragmaticVillainy: He doesn't snap Batman's neck when he has the chance for two reasons: breaking bones was passe and Batman's defeat had to be the ultimate defeat.
* ShoutOut:
** His appearance and name are a reference to ''[[Film/TwoThousandOneASpaceOdyssey 2001]]''.
** His death is similar to the destruction of [[Film/TheTerminator the Terminator]].
* TomatoInTheMirror: He doesn't actually know he's a robot.
* UltimateLifeform: Calls himself "Gotham's Ultimate Criminal Mastermind". it's even the name of the episode he appears in.
