Batman: The Brave and the Bold characters:
Heroes | Villains
Heroes | Villains
Black Manta (David Hyde)
Black Manta is a criminal from the surface world who frequently clashes with AQUAMAN.
- Badass Baritone: When he suddenly starts singing in "Mayhem of the Music Meister!"
- Color Character: He wears black and it's in his name.
- Disproportionate Retribution: In AQUAMAN's sitcom, he tries to blow up the hero's house because Fluke keeps destroying his garden.
- Even Evil Has Standards: Despite enjoying creating world-wide chaos, Black Manta finds being made to sing against his will despicable.
- Evil Is One Big, Happy Family: Subverted. Black Manta betrays Orm the first chance he gets, mentioning he'd been waiting to do that "within five minutes" of meeting him. Later played straight though, since he works with the notoriously humanist Gorilla Grodd with no quarrel.
- Evil Sounds Deep: Amplified by his helmet to sound deeper. Except when he sings, where he's surprisingly shrill.
- Eye Beams: A major upgrade in powers from one of his earliest animated incarnations.
- Sitcom Arch-Nemesis: Unsurprisingly, his role in AQUAMAN's sitcom."That old Black Manta is bound to annoy!"
Catwoman (Selina Kyle)
Batman has never met another villain quite like the elusive and illustrious Catwoman, and not even a complex death trap can keep the two from friendly flirting.
- Abhorrent Admirer: During "Death Race to Oblivion!", she gains the attention of Woozy Winks. She hisses at him.
- Animal Motifs: Cats, naturally. She's based on them, likes using them, likes stealing cat-based objects in her crimes...
- Anti-Villain: Seen as such by Batman, who points out to Green Arrow she's a thief rather than the usual deranged killers and criminal masterminds he faces. Her targets are also the rich and museums for the most part. Both of which are lower on the Batman's list of priorities.
- Dating Catwoman: Of course. Every altercation between Batman and herself displays heavy amounts of mutual attraction and Unresolved Sexual Tension.
- Hunting the Most Dangerous Game: Played With. She engages in this with Batman during a cold opening, though with the intent of capturing and seducing him as a opposed to killing. After failing, she sadly laments the most dangerous game is in fact love.
- Ms. Fanservice: As per usual for the character. She's a woman who goes around in a purple dress that shows off her legs and tends to friendly flirt with Batman.
- Purple Is Powerful: She wears the same costume that her comic book counterpart wore in the Golden and Silver Age.
- She's Got Legs: This is the Catwoman whom we are talking about. Her long toned yet shapely legs are presented through the dress that she wears.
- Single-Target Sexuality: "My real prey is, and shall always be, Batman."
Clock King (William Tockman)
The first villain to appear in The Brave and the Bold, Clock King has simple goals in life: assemble a clock-themed group of henchmen in a clock-themed secret lair, construct elaborate clock-themed traps and/or weapons, and use them to rob banks and/or kill Batman.
- Adaptational Dumbass: This version never actually shows off his trademark Clock King precision planning.
- Adaptational Wimp: He has neither the Clock King planning abilities, nor the Time Master powers. He's basically just a normal guy wearing a silly clock-themed costume.
- Badass Cape: A fancy-looking one with a fur trim.
- Badass Normal: He's actually pretty ripped. He was once shown lifting weights in prison.
- Clock King: While worth mentioning simply because of the name, he has yet to demonstrate the precise timing to be worthy of this trope.
- Even Evil Has Standards: He, Black Manta and Gorilla Grodd all find being controlled by the Music Meister despicable.
- Funny Foreigner: Speaks with a German accent.
- Jobber: Made a few appearances, but never got the time of day as the villain of a full episode. He'd appear, get beaten and the episode would move on.
- Pimped-Out Cape: Very fitting for a bad guy who deliberately bases himself off royalty.
- Starter Villain: He is the first villain to appear in the series, and makes more appearances after that. However, the actual villain with a relevant role in the plot is Kanjar Ro.
The Crimson Cloak / Clayface (Basil Karlo)
A mysterious being haunting Batman, presumed to be the ghost of Sam Scarlett.
- Canon Character All Along: The Crimson Cloak at first appears to be a new villain created for the movie, but is actually Clayface in disguise.
- The Heavy: Is the primary threat for most of Scooby-Doo! & Batman: The Brave and the Bold, but is working for the Riddler.
- Tragic Monster: Clayface did very little out of genuine malice, instead acting on the Riddler's orders in exchange for the cure to a very horrifying degenerative disease. Daphne even openly says she feels sorry for him as he's carted off.
Darkseid is the ruler of the planet Apokolips and the most feared being in the universe. He successfully conquered the Earth defeating both Batman and his new Justice League, but is forced back to Apokolips from an unexpected source.
- Always Accurate Attack: His Omega Beam, ultimately subverted in that Batman managed to dodge it when he used it.
- Arc Villain: Of "The Knights of Tomorrow!" and "Darkseid Descending!".
- Curb-Stomp Battle: Easily defeats the Justice League, and Batman is utterly outclassed by him, even after convincing Darkseid to fight without the use of his powers.
- The Dreaded: Stated by Batman to be the most feared and evil being in the entire universe.
- No-Sell: Deflects a combined attack from AQUAMAN, Fire, Ice, Booster Gold, and Guy Gardner without any effort.
- No-Holds-Barred Beatdown: Batman challenges Darkseid to a physical fight without any of his powers. It does not end well for the Bat.
- Physical God: Played with; since it's a children's show Darkseid is never called a god outright, but Batman states he is so powerful that for all intents and purposes Darkseid is a god.
- Powers Do the Fighting: Defeats the Justice League without even touching them. Batman questions how long it has been since Darkseid actually fought using his physical strength instead of his godly powers, and Darkseid admits it has been "eternity," which actually convinces him to fight using his bare hands since he finds the idea fun after having not done so for so long.
- Suicide Mission: Inverted. Batman taking on a physically far superior entity was not his finest moment.
Doctor Thaddeus Bodog Sivana
A mad scientist who plagues Fawcett City with his demented schemes, with assistance from his children, requiring the intervention of Captain Marvel.
- Arch-Enemy: To Captain Marvel.
- Bald of Evil: Not a hair on his head, and evil as they come.
- Daddy's Little Villain: His children, Thaddeus Junior and Georgia, help out in his mad schemes.
- Eviler Than Thou: Pulls this on Black Adam, duping the former Champion into defeating Captain Marvel and the Wizard for him and then stealing his powers. Later ends up on the receiving end from Mister Mind.
- Gonk: Short, hunched, bald with pointy ears, coke-bottle glasses and an overbite. He's not winning any beauty contests any time soon, that's for sure. Thaddeus Junior and Georgia have inherited his looks.
- Mad Scientist: He is the original comic mad scientist, after all.
- Manipulative Bastard: Plays both Captain Marvel and Black Adam to seize the Wizard's power in his first appearance.
- Schmuck Bait: Batman manages to deprive him of the Wizard's power by wrongfully pronouncing "Shazam". Sivana can't help but correct him, at which point...
An orphan empowered with powers of Order and Chaos, he was suppose to keep the balance. However, the opposing sides of his psyche broke his mind.
As far as Equinox is concerned, there's a delicate balance between good and evil, and he's the only one concerned with preserving it. If some bad guy gets too powerful, he'll take them out to keep evil in check...and if a hero starts wiping out bad guys left and right, Equinox will try to keep them in check too.
- Aborted Arc: After his defeat in "Fate of Equinox" it was revealed his mind got shattered into 12 shards and were scattered across time and space. The only one to show up is Hate!Equinox who appears in "Time Out for Vengeance!" Unfortunately, due to the cancellation of the show after Season 2, none of the other Equinoxes ever show.
- Ascended to a Higher Plane of Existence: He manipulates Batman into killing his mortal form, so that once he is free of his body he is able to absorb the powers of the Lods of Order and Chaos to become a god-like being.
- Arch-Enemy: One of Batman's most personal enemies. Equinox at first saw Batman as a Worthy Opponent, but later came to hate Batman so much he actually attempted to erase Batman from existence.
- Balance Between Order and Chaos: A very good example on how arbitrary this justification can be.
- Big Bad: His presence is built up during a few cold opens in season one, leading him to become the main antagonist near the end in "The Fate of Equinox!". "Time Out for Vengeance!" set him up as the main antagonist of the entire show, before it prematurely ended.
- Canon Foreigner: An original character to the show. Though he is very similar to an existing character called Libra, which would make this a case of Adaptational Name Change.
- Expy: Shares a similar backstory and obsession with balance to Silver Age Libra.
- Faux Affably Evil: Early days he seems to be genuine in his respect towards Batman and may have been Affably Evil. Over time he switches over to Faux when his goals become more warped and self-serving, along with his respect for Batman growing into hate for constantly being thwarted.
- A God Am I: After taking the power of all the Lords of Chaos and Order, he pretty much is this.
- Impossible Task: He was charged from birth with maintaining the balance between chaos and order, a task which by his own admission was impossible.
- Knight of Cerebus: Lacks any of the usual camp from the show's villains and nearly destroys the universe.
- Kung-Fu Wizard: Can overpower Batman in hand to hand and Dr. Fate in magic simultaneously.
- Literal Split Personality: His consciousness was shattered into 12 pieces and shattered throughout time and space. Hatred!Equinox was the first to appear and was killed by four different versions of Batman from across time.
- Not Quite Dead: After Batman destroyed him, his consciousness was shattered into 12 parts and hurled throughout time and space.
- Omnicidal Maniac: Eventually snapped and tried to destroy and recreate the universe in his own image.
- One-Winged Angel: Absorbed the powers of Chaos and Order to grow into a gigantic, armored version of him with reality warping powers. Even when Batman is given the powers all the shows guest heroes who appeared up to the point in the series, he still can't beat him.
- Hatred!Equinox merged all of his Mecha-Mooks into a giant robot and possessed it to try and kill Future!Batman.
- A Pupil of Mine Until He Turned to Evil: As stated by the Lords of Chaos and Order.
- Reality Warper: After his Thanatos Gambit, he gains the powers of Order and Chaos with no limits and nearly destroys the universe.
- Remember the New Guy?: Stands out as one of the few aversions in the show, Batman has no idea who he is when they first meet.
- Thanatos Gambit: He dies in an explosion during a fight with Batman and Doctor Fate in "The Fate of Equinox!"—but his soul persists, and is now able to freely access the powers of Order and Chaos with the limitations of his worldly body gone.
- Villainous Breakdown: After Batman pointed out that he wasn't perfectly balanced, he snapped and his body began to crack along with his mind, allowing Batman to defeat him..
- With Great Power Comes Great Insanity: The strain of his responsibilities eventually took a toll on his mind.
- Yin-Yang Bomb: He has mastery of both Order and Chaos magic.
The Faceless Hunter
- Adaptational Badass: The Faceless Hunters of the comics weren't exactly pushovers, but a single one would never have been able to best so many heroes with such ease.
- Alternate Company Equivalent/Expy: To the Silver Surfer, with a twist. That twist being he's everything the Surfer isn't. Norrin became the Surfer in exchange for Galactus sparing his world. The Hunter became Starro's herald in exchange for Starro destroying his world.
- Big Bad: After serving as The Heavy for the Starro arc, the Hunter takes over as the main antagonist after his master's destruction.
- The Blank: he has no face.
- Corrupted Character Copy: The Faceless Hunter, herald to Starro the Conqueror. Much like the Silver Surfer, the Faceless Hunter made a deal with Starro to become his scout when the latter invaded his planet. Turns out the deal was to destroy the planet, as the Faceless Hunter's pacifistic people looked down on his occupation. Starro, finding that he couldn't control beings without faces, was originally going to simply leave.
- Dragon Ascendant: After Starro is killed, he pretty much becomes the Big Bad of the story arc.
- Dragon with an Agenda: He'll do whatever Starro asks in exchange for the chance to hunt prey.
- The Faceless: Duh.
- Hunting the Most Dangerous Game: His main motivation.
- Knight of Cerebus: Lacks any of the camp the usual villains have, and is much more evil.
- No-Sell: Batman's Batarangs don't seem to hurt him and he can even absorb the powers of other heroes which is what he does when Booster Gold arrives and uses his light beams on the Faceless Hunter which Faceless Hunter stops by putting his hand up in the air to absorb the attack.
- Villain Respect: B'wana Beast's power strikes a chord with him.Faceless Hunter: You interest me.
B'wana Beast: Okay, I get it. You think I'm a joke. Join the club.
Faceless Hunter: A joke? No. I've never been more impressed.
Gentleman Ghost (Jim Craddock)
"Gentleman" Jim Craddock was a notorious highwayman in 19th-century England, but as his fame spread, he began to seek something more than simple wealth. In search of the ultimate power he made a deal with the demon Astaroth— in exchange for ten human souls, he would be granted immortality. Unfortunately for him, Astaroth's definition of "immortal" didn't quite match up with Craddock's. When the courts ordered Gentleman Jim hanged for his crimes, his body died, leaving his soul to wander the earth as "Gentleman Ghost," seeking revenge on the living— particularly Batman. As a ghost, Craddock is nearly immune to tangible weapons— only the Thanagarian element "Nth Metal" can touch him if he doesn't want to be touched.
- Achilles' Heel: He has a weakness to Nth Metal like all ghosts.
- Adaptational Villainy: Gentleman Ghost is typically, well a gentleman, while this version just pretends to be one. This Gentleman Ghost boasts crimes such as stealing souls to grant himself immortality, or raising an undead army to lay waste to London, making him far more heinous than his comics counterpart.
- Adaptation Origin Connection: In addition to being a Rogues' Gallery Transplant, this Gentleman Ghost's origins are directly caused by Batman, having been foiled by Batman while he was alive and then responsible for him becoming a ghost.
- Arch-Enemy: Batman is his, since he was responsible for his death.
- The Blank: Played with. He does have a face, but it's usually rendered invisible and only his top hat and monocle can be seen. However there are certain instances like lightning strikes or when he is hit by Nth Metal will his true face be revealed.
- Deal with the Devil: He wanted immortality and Astaroth promised his soul would never pass from the Earth.Etrigan: You're a foolish man to take that deal! A demon's promise is never real!
- Dem Bones: His true face is decaying and skeletal.
- Dragged Off to Hell: His final fate is getting pulled into the ground by his undead army.
- Evil Brit: He is an Englishman who menaced London when he was alive.
- Evil Laugh: Gives off demonic cackles.
- Hoist by His Own Petard: He is ultimately defeated by his own undead army where he gets Dragged Off to Hell.
- Immortality Seeker: His goal back when he was alive, leading him to do a Deal with the Devil. It doesn't go quite as he had planned, with Astaroth pulling an Exact Words on him so that rather than being unable to die, only his soul would remain while his body expired.
- Never My Fault: Despite being warned by a time-travelling Batman that Astaroth was deceiving him about being given immortality, Craddock blames the Caped Crusader for his status as a ghost, and swears revenge.
- Pet the Dog: He does genuinely inform a civilian that they were being scammed by a phony psychic, although he may have done so for the fun of ruining the fake's reputation.
- Revenge Before Reason: After being rendered a ghost, he swears vengeance on Batman, rather than the demon who cursed him, or the people who executed him.
- Ripped from the Headlines: He is implied to be the show's version of Jack the Ripper back when he was alive. Although the myth also got tied together with Sherlock Holmes.
- Rogues' Gallery Transplant: While he has fought Batman before, he is typically a Hawkman villain. The show makes him a very personal enemy to Batman, although he does become Katar and Shayera's enemy in the tie in comics.
- Unexplained Recovery: Despite being Dragged Off to Hell in his second appearance, he later returns for several cameos with no explanation how he returned to the land of the living.
- Victorian London: Given that when he was alive he coexisted with Sherlock Holmes, he is also presumably from this era.
- We Will Meet Again: At the end of his Origin Story episode, following his execution and his rising from the grave as a ghost, he says this:"No matter how many centuries I have to wait to face you, Batman, I will find you again, and I will have my revenge!"
- Wicked Cultured: He's a very sophisticated gentleman, but is pure evil.
One of the more frequently featured villains in the show. Grodd helped set the tone for the series in the second episode by turning Batman into an ape on Dinosaur Island.
- Adaptational Nice Guy: By comparison to his comic self, who is prone to vicious and cruel acts that signify what a monster he is, Grodd here is more Laughably Evil and seems to genuinely believe he's fighting for apekind. He's also comrades with Monsieur Mallah, who he brutally murdered in "Salvation Run".
- Badass Bass: In "Mayhem of the Music Meister!"
- Blatant Lies: He's had that utility belt that looks like Batman's for years. You've just never seen him wear it.
- Breather Episode: Was the featured villain of the very silver aged "Gorillas In Our Midst!" after the Darker and Edgier "Chill of the Night."
- Even Evil Has Standards: As with Clock King and Black Manta, he finds Music Meister's hypnotic control "dastardly, despicable, and imminently kickable".
- Fantastic Racism: Against humans, and any other sapient species he can find.
- Fantastic Slur: A good way to annoy Grodd is refer to him as a monkey. It invariably gains an annoyed "MONKEY?!" from him.
- Hypocrite: Grodd will go on and on about how stupid humans are... but it doesn't stop him working with them to suit his own ends.
- Hypocritical Humour: One episode has him claim Batman has an unhealthy obsession with him. A later episode shows Grodd has an unhealthy obsession with Batman.
- Insufferable Genius: In the words of Batman, "Grodd considers himself a genius first, and an ape second."
- No Indoor Voice: The amount of lines he doesn't shout can be counted one hand.
- Rogues' Gallery Transplant: Usually an enemy of the Flash, this one constantly battle Batman and even ends up in Arkham.
- Unexplained Recovery: Was turned human at the end of his first appearance. After a cameo as a human he's back to normal.
- Well-Intentioned Extremist: Unlike his deranged and murderous self from the comics, this version of Grodd genuinely believes that humans are harming the planet to the point that it will soon be unsavable. As such, Grodd believes that a planet ruled by apes will restore the planet's ecological balance.
- Worthy Opponent: Considers Batman one."Batman. The one human worthy of my intellect."
This incarnation of the Clown Prince Of Crime is as clownish as he's ever been, but underneath the fun-loving, acid-pie-throwing exterior, he lives to destroy Batman at all costs. Which makes it a bit confusing when he has to deal with two of them.
- A Day in the Limelight: In the episode "Joker: The Vile and the Villainous!", he becomes the main focus for a change.
- Adaptational Nice Guy: He's as dangerous as ever, but he genuinely respected and wanted to help the Weeper. He also (though rather grudgingly) saved a kid's life when he teamed up with Batman, and doesn't seem to be abusive towards Harley.
- Affably Evil: For the most part, he comes off as friendly and personable even to his enemies — and unlike most Post-Crisis takes on the character, nothing about it is an act.
- Ax-Crazy: Even in the Lighter and Softer Silver Age atmosphere, he retains some of his murderousness from his Golden Age and modern interpretations.
- Badass Normal: Joker has no powers of his own, but with his intelligence and various tricks and gadgets is able to fight and even beat various super-powered foes.
- The Bad Guy Wins: In the episode "Triumvirate of Terror" after Lex Luthor's plan for Joker, him, and Cheetah to switch opponents works.
- Beware the Silly Ones: He might be somewhat nicer than a lot of Jokers, and is as silly as any, but he's still an insane psychopath and extremely dangerous. Notably, he's the Joker who got an "Emperor Joker" adaptation, with all that comes with.
- Cool Guns: His bazooka which he aims towards Plastic Man, Green Arrow, Shazam, and Aquaman's general direction in the episode "Night of The Batmen".
- Crazy-Prepared: He's got several gadgets that combat Batman's in "The Vile and the Villainous."
- Crouching Moron, Hidden Badass: Particularly his "what-if" future incarnation.
- Death Trap: He's put Batman through a few. "Emperor Joker" sees him put a completely helpless Batman through many in quick succession.
- Diabolus ex Machina: Embodies this in the cold open teaser for "Joker: The Vile and the Villainous". Kamandi and Tuftan appear to be winning against Misfit's Mecha-Mooks, but then suddenly a time portal opens, revealing a familiar pointy-featured silhouette walking out to provide aid... only for an extending boxing glove to spring out and flatten the heroes. Then, after teaming up with Misfit to defeat the Tiger Empire, he ends up destroying their timeline's entire Earth by simply pressing the wrong button on a nuclear warhead control panel.
- Disney Villain Death: His hypothetical death in "The Knights of Tomorrow!" has him plunge into the river. They Never Found the Body.
- Enemy Mine: He's forced to team up with Batman when Owlman comes to Gotham.
- And in a surprisingly dark twist for the series, his desire to die at Batman's hands to make him feel the guilt is eventually mentioned.
- Even Evil Has Standards: He's thoroughly disgusted when he discovers Batman's rather Orwellian plans to create a mass surveillance system to spy on Gotham 24/7 and punish people before they've even committed crimes.
- Evil Counterpart: "Joker: The Vile and the Villainous" emphasises his role as Batman's opposite by revealing that in his spare time he helps out other supervillains, on both his world and beyond. He even somehow makes his way to Kamandi's timeline to team up with Misfit.
- Evil Laugh: If he didn't write it he at least signed the Grandfather Clause.
- Fourth-Wall Observer: Provides a play by play in Death Race to Oblivion. Just because he can.
- Hoist by His Own Petard: In the episode "Night of The Batmen" after he attempts to zap Batman with a joybuzzer attached to his glove. Batman of course comes prepared for a moment such as this one by neutralizing the electric discharge from the joybuzzer.
- Homage: This version of the Joker is both an homage to Dick Sprang's Joker's design and Cesar Romero's performance on the '60's Batman show.
- Hostile Show Takeover: "Joker: The Vile and the Villainous", complete with an alternate title sequence depicting him bouncing around on a pogostick, scaling a building with plungers and driving around the Jokermobile.
- Hyperspace Arsenal: His primary method of combat.
- I Call It "Vera": In "Emperor Joker!", after the Joker is given Reality Warper powers, he uses a springed, giant Power Fist on Batman and calls it, "My very own Hammer of Injustice!" (a parody of Batman's "Hammer of Justice")
- Joker Immunity: Lampshaded in "The Knights of Tomorrow!""I've been blown up, dropped down smokestacks, fed to sharks—I'm the Joker. I always survive!"
- The Knights Who Say "Squee!": He's utterly ecstatic when he meets the Weeper, whom he idolises as an inspiration not just for himself but for all supervillains. This unfortunately does not have real life subtext as the Joker's debut actually predates the Weeper's by a couple of years, though they certainly are Golden Age era peers.
- Large Ham: He's not the same otherwise.
- Pet the Dog: He's a genuine fan of washed-up villain the Weeper, and even tries to help the latter get back to his prime.
- Put the "Laughter" in "Slaughter": He laughs as much as you'd think when he repeatedly kills Batman as Emperor Joker.
- Reality Warper: Thanks to Batmite in "Emperor Joker!"
- Red Baron: "The Clown Prince of Crime", "The Harlequin of Hate".
- Rocket Punch: Tries delivering one (which turns into a bomb) to Batman in "Emperor Joker!"
- Shock and Awe: In "Emperor Joker!" he uses his superpowered Electric Joybuzzer when powered up to shock Batman into submission, which is something worthy of Emperor Palpatine of Star Wars.
- Unwitting Instigator of Doom: In the teaser for "Joker: The Vile and the Villainous", he accidentally blows up the Earth in Kamandi's future, killing himself along with it.
- Villain Episode: "Joker: The Vile and the Villainous". They even changed intro.
- Villainous Harlequin: This version owes more to his 60's appearances than his modern Monster Clown ones. But then again, there's "Emperor Joker!"...
- Villain Protagonist: In the episode "The Vile and the Villainous", where the roles switch and Batman's the antagonist.
- Villain Respect: The Joker deems the Weeper to be the greatest villain of all time due to him codifying gimmick-themed supervillainy as everyone knows it. When they team up to fight Batman, Joker resolves to bring back old Weepy's moxie and get him back in the villain game.
- Villain Song: ''Where's the Fun in That?" in "Emperor Joker!"
- What Does This Button Do?: In The Teaser to "Joker: The Vile and the Villainous". He ends up blowing up the (alternate future) Earth.
- Where's the Fun in That?: The theme of the above Villain Song in "Emperor Joker!", in response to Harley Quinn asking him if he's going to unmask Batman.
- He also uses this phrase in the episode where he teams up with Batman in reference to being a goodguy.
- Wild Card: He might be an insane psychopath, but he'll gleefully team up with the Bat if he thinks it will be fun or amusing. Occasionally overlaps with The Only One Allowed to Defeat You.
A power-hungry space-pirate and Arch-Enemy of the Blue Beetle.
- Adaptational Curves: Compared to his often-slender comic book counterpart.
- Arch-Enemy: Of a previous wielder of the Blue Beetle scarab before it came into the possession of Dan Garrett.
- Badass Normal: He doesn't seem to possess any powers other than standard hand-to-hand combat and instead relie on advanced technology and cunning.
- Rogues' Gallery Transplant: Commonly associated with being an enemy of Green Lantern, Kanjar Ro makes no mention of Green Lantern and instead is an enemy of Blue Beetle here though they've only crossed paths once in the series and Kanjar Ro's later appearances involve him crossing paths with the Metal Men and Adam Strange.
- Starter Villain: Aside from Clock King being introduced, Kanjar Ro is the first villain to appear in the series with a much more relevant role in the premiere.
- Would Hurt a Child: He has no problems torturing a teenage boy whatsoever.
Exactly who Owlman is has never been revealed, but what we do know is that he's as evil as Batman is good. Exactly as evil. Batman's counterpart in an alternate universe, Owlman led a team of other such evil twins against the heroes of his world, and eventually defeated and imprisoned all but one. Now, with his Earth subjugated by the Injustice Syndicate, Owlman's sights are set on the conquest of other worlds.
- Animal Motifs: Owls, right down to a gadget that includes nightvision.
- Arc Villain: Of the Injustice Syndicate two-parter ("Deep Cover for Batman!" and "Game Over for Owlman!").
- Costume Copycat: He steals an earlier version of Batman's outfit, and uses it to ruin Batman's reputation.
- No Name Given: His identity is never revealed, though if he's anything like his comic version, it's Thomas Wayne Junior.
- Pungeon Master: Reels off a particularly painful Hurricane of Puns to his captured enemies.
- Shadow Archetype: Is like Batman, but uses his intelligence for evil.
- Shout-Out: Owlman's costume is similar to Justice Lord Batman. When he dresses up as Batman, he uses Batman's original costume from the comics◊.
The Riddler (Edward Nygma)
- Voiced by John Michael Higgins
Edward Nygma began his criminal career as a lab assistant to Professor Milo. When an experiment in creating a teleportation device went haywire and Batman arrived on the scene to stop it from destroying the city, he and Milo would be rescued by Batman, while another assistant ended up sucked into the portal. This would end up haunting Batman for much of his career and Nygma ended up deciding to move onto greater things.
The Riddler's aka Edward Nygma M.O. became warning the Gotham City Police Department in advance with puzzles about his latest crime. Donned a question mark-covered business suit and armed with a cane with a question mark handle, the Riddler's compulsion is his greatest strength and weakness. Rather than kill his prey, Riddler often sets them up in an elaborate deathtrap that tests their intelligence.
- Adaptation Origin Connection: Riddler is a former lab assistant to Professor Milo. In the comics, the two are unconnected.
- Big Bad: Of Scooby-Doo! & Batman: The Brave and the Bold
- Calling Card: Cannot commit a crime without sending one of his trademark riddles.
- Cane Fu: Is an expert in using his cane as a weapon.
- Catchphrase: "Riddle me this !"
- Death Trap: His preferred method of disposing of enemies.
- Evil Laugh: Has a high-pitched giggled.
- Lean and Mean: Is skinny compared to most of Batman's foes.
- Secondary Color Nemesis: Wears a costume of green and purple.
- Alternate Company Equivalent: to Marvel Comics' Galactus. (Actually Starro came first, but the whole planet-devouring shtick is more Galactus' than his.)
- Big Bad: Of a Story Arc introduced on in the show's Cold Openings, where The Faceless Hunter is gathering most of the superheroes to become Hive Mind slaves. Their roles reverse after Starro is killed by Earth's heroes, with the Faceless Hunter taking over as the main villain and the now, apparently mindless creature he turns Starro's remains into serving his destructive whims.
- Disc-One Final Boss: Is killed by the heroes, with the Faceless Hunter taking over using his mindless remains.
Baby Face (Alfonso Face)
Alfonso Vincenzo Giuseppe Face is a ruthless gangster with the face of a young child, but a manly voice of Edward G. Robinson. Though when he is defeated he whines like a baby, and he also wears diapers.
- Berserk Button: Don't disrespect his gal.
- Canon Foreigner: He was created for the series.
- Even Evil Has Loved Ones: He'll quite happily dish out the hurt to our heroes or indeed any innocent Red Shirt, but he genuinely loves Miss Manface and has made an honest woman of her by the time of "Night of the Huntress".
- Expy: Quite similar to Baby Doll from Batman: The Animated Series with both being villains who suffer from conditions that make them look like children. Both also get into an Unholy Matrimony with another villain.
- Guns Akimbo: With twin Thompson SMGs.
- Kissing Discretion Shot: This happens with Mrs. Manface. We cut away to a guard's reaction, which is more worthy of a Gory Discretion Shot.
- Psychopathic Manchild: With special emphasis on the "child."
- Recognition Failure: He has no idea who Elongated Man is, but he does know about Plastic Man.
- Tiny-Headed Behemoth: He's a broad, hulking brute with a baby's head on his shoulders.
- Verbal Tic: Like Edward G. Robinson, see?
Black Adam / Teth-Adam
A former champion of the wizard Shazam, five thousand years ago. Black Adam turned against the wizard, and was banished into the depths of space, until Doctor Sivana managed to summon him back to Earth.
- Fallen Hero: He became corrupted by his power, and tried to take over the world, and so the Wizard banished him to "the furthest star".
- Flying Brick: Black Adam has all of Captain Marvel's power, and absolutely none of his kindness or compassion. Adam is one foe Batman is completely outclassed by.
- Hair-Trigger Temper: Just generally irritable. Much of Sivana's partnership with him is keeping Adam calm long enough to get what he wants, before Adam decides to tear his head off.
- Not So Similar: Billy Batson is initially eager at the thought of finding someone like him, but the Wizard sets him straight. Black Adam isn't like Billy at all.
- Oh, My Gods!: Tends to swear by the gods of his time.
- The Poorly Chosen One: The Wizard thought he was a good choice as champion. Several millennia later, he regrets his choice, which apparently comes with a "no backsies" rule.Wizard: I was a fool, for failing to see the rot within your heart.
- Red Baron: He identifies as the Thunder King.
- Villain: Exit, Stage Left: After being depowered by Doctor Sivana, the suddenly very old Teth Adam manages to slink away while everyone else is distracted.
Blockbuster (Mark Desmond)
While he simply appears to be a scrawny little punk, whenever Mark Desmond ingests the right chemicals, he becomes the super-strong Blockbuster, though his intelligence takes a hit when he does. Desmond's crimes are fuelled by the need for more funds. Chemicals don't come cheap, after all.
- Adapted Out: Absolutely no mention of Bruce Wayne saving his life like in the comics is mentioned.
- Age Lift: Much, much younger than either of his comics counterparts.
- Adaptational Villainy: The comics Blockbuster was only a villain because of his loyalty to his older brother Roland. This version is evil of his own free will.
- Composite Character: He is Mark Desmond, but being a criminal of his own accord comes from the second Blockbuster, his brother Roland.
- Evil Sounds Deep: Desmond's voice is as high-pitched as you'd expect a kid's to be. Blockbuster speaks in guttural growling.
- False Innocence Trick: Tries pulling one when confronted in mid-crime by Batman, since he looks like an innocent kid being hassled by the Dark Knight, giving him enough time to ingest his serum.
- Hulking Out: Practically lampsahded when Blockbuster declares himself "strongest".
- Tempting Fate: "Now Blockbuster is strongest one there is!" Cue the appearance of Earth's Mightiest Mortal.
A genius with his mind stuck in a robotic body, the Brain uses his intellect to get back at the world by committing heinous crimes.
- Adaptational Badass: Minor case. In the comics he posed no physical threat as his body had no means of defense. Here, while still one of the weaker characters, he can produce weapons to defend himself.
- Brain in a Jar: Naturally.
- French Jerk: He is French, as in the original comics, and the series even gives him a French accent.
- Good Colors, Evil Colors: His brain is, for some unexplained reason, green, while his robotic body is black and his "eyes" and "mouth" are red.
- Kneel Before Zod: "Bow before the Brain!"
- The Man Behind the Man: He's pulling Chemo's strings in "Journey to the center of the Bat".
- Rogues' Gallery Transplant: Normally a foe of either the Doom Patrol or Teen Titans, he faces Batman in this series.
- Weaksauce Weakness: His tin-can body has the little problem of being difficult to right when knocked over. Oops.
- Basement-Dweller: He still lives in his mom's basement, which is the first place Huntress looks for him.
- Fat Bastard: He's a chubby, slovenly nerd who doesn't even wear pants at work, and that work is tattling for supervillains.
- Information Broker: For supervillains, he supplies knowledge on what superhero's doing what, in exchange for money.
Catman (Thomas Blake)
- Voiced by Thomas F. Wilson
Thomas Blake was world renowned for capturing wild cats. However, Blake became bored with hunting and had wasted his vast fortune. He became a thief called Catman. Catman's costume made from an ancient African cloth that is rumored to give its wearer nine lives. Nonetheless, Catman was accused of stealing the cat theme taken up by Catwoman.
- Animal Motifs: Cats, although not quite to the same extreme as Catwoman.

- Spear Counterpart: To Catwoman.
A criminal who has based himself on a 17th century swordsman.
- Recurring Character: After his debut appearance in the episode "The Eyes of Despero", he would later go on to make three additional episode appearances in the episodes "A Bat Divided" (hanging out at the villains bar before he is zapped by a tazer from Batman), "Night of the Batmen" (as one of the many criminals in Gotham who sees Batman's absence from crimefighting as his opportunity to commit crimes), and "Bold Beginnings" (in which he distracts Batman and Green Arrow by using Ruby Ryder's hostage situation as his opportunity to reveal that Ruby Rider never needed to be saved at all before her true colors are soon revealed) .
- Ye Olde Butcherede Englishe: Possibly the Cavalier's most heinous of crimes is his constant use of mangled faux-Elizabeathan English. It gets a Lampshade Hanging from Batman in one appearance.Batman: (after having just heard the Cavalier speak) Somewhere, Shakespeare is spinning in his grave.
Cheetah (Priscilla Rich)
- Animal Themed Super Being: Type I.
- Arch-Enemy: One of Wonder Woman's main opponents.
- The Bad Guy Wins: After her plan to already be inside the Fortress of Solitude first without Superman knowing before she reveals herself to the man of steel himself which leads to her revealing to him she's wearing a magic based amulet around her neck (that both powers her up and exploits his weakness to magic) as well as wearing kryponite laced nail polish, both which makes Superman vulnerable to being defeated by Cheetah with little difficulty.
- Composite Character: Of herself. Even if her real name is never mentioned, her looks and personality correspond to Priscilla Rich, the Golden Age Cheetah, while her strength and abilities seem to have a magical origin, like the third Cheetah, Barbara Ann Minerva.
- Curb-Stomp Battle: Gives one to Superman after she gets an amulet than enhances her powers, and covers her claws with kryptonite.
- Lightning Bruiser: Not just as fast and agile as it's expected from a cheetah-themed character, but also strong and resistant enough to fight evenly with Wonder Woman.
- Straw Feminist: She doesn't like that Lex Luthor doubts she'll be able to fight Superman, and, after defeating the hero, Cheetah takes great delight in mocking him.
- Vitriolic Best Buds: With Joker and Luthor.
Crazy Quilt (Paul Dekker)
An ex-painter who leads a double life as a master thief, he is blinded during a battle with Batman and Robin. While in prison, he volunteers for an experimental procedure that would restore his vision. There is a side-effect, however: Even though he can see, he can only see in blinding, disorienting colors. Crazy-Quilt's wears a helmet that allows him to hypnotize his victims using flashing lights of various colors. It can also project lethal laser beams, blinding lights, and functions as artificial eyes since his own eyes no longer function; the lenses feed their input signal straight into his brain.
- Arch-Enemy: To Robin
- Energy Weapon: He shoots laser beams out of his helmet.
- Eye Scream: Quilt catches an eyeful of his own lasers. It doesn't completely blind him, but his eyesight's so badly damaged he might as well be.
- It's Personal: His motivation.
- Mad Artist: He calls himself "Crazy Quilt" and lives up to the name.
- Sanity Slippage: Dekker wasn't terribly sane to begin with (Crazy Quilt), but losing his sight makes him even more demented.
An alien despot obsessed with conquering the universe, Creature King first appears in the episode "Bold Beginnings!" during the teaser with a mind control helmet which he uses on several astrodactyls and moon apes. Batman later knocks him out, making the mind control helmet fall off his head in the process.
- Aliens Are Bastards: Oh yes very much so.
- Berserk Button: After he realizes Jan and Jace know what he's up to, he is not happy about it and sends his pet wyvern after the two.
- Bizarre Alien Biology: The Creature King himself who is no taller than a dwarf, has an appearance like that of a goblin (not to mention having pointy ears like one), and has fangs similar to vampire fangs.
- Hoist by His Own Petard: After his mind control is destroyed, his creature minions (including a maroon hodag with dark blue spikes, a red three eyed slug, and a metallic blue colored lava monster) get their long overdue revenge on their former master.
- Look Behind You: Batman does this to get the orange skinned alien's attention before knocking him out with a punch.
- Mix-and-Match Critters: Creature King's creature minions whether it's his astrodactyls (which resemble both bats and Pterodactyls hence their name) or his wyvern (which resembles a snake and a dragon)
- The Napoleon: He's as evil as he is short.
- No Name Given: His real name is unknown.
- One-Shot Character: After his mind control helmet is destroyed and the astrodactyls and moon apes get their long overdue revenge on their former master, it can be assumed that he died offscreen.
- Disproportionate Retribution: In the teaser for "Duel of the Double Crossers!" he has no problem with destroying a few cars, a stone monument, and a building. He also blew up a truck full of oil after being sent flying from an electricity blast from Black Lightning.
- Evil Counterpart: With him being an adversary of Hal Jordan, this one goes without saying.
- Evil Sounds Deep: He is voiced by Kevin Michael Richardson.
- Rogues' Gallery Transplant: Like in the previous Justice League cartoon, Despero is again treated as an enemy of the Green Lantern Corp (and Batman this time around) instead of a Martian Manhunter foe.
- Villain Has a Point: Mocks Batman for the few remaining Green Lanterns he is stuck with. Batman attempts to counter that he can rely on Sinestro, only for Despero to reveal Sinestro's past villainy and that the two of them aren't so different.
- The Voiceless: In the episode "Duel of the Double Crossers!" apart from grunting noises he makes when lifting up Metamorpho (in lead block form) and tossing him away.
- You Can't Fight Fate: As part of Despero's plan to mind control Batman, the dark knight himself is immobilized by three golden rings and can't move as a result.
Doctor Double X / Simon Ecks
A man with a very literal split personality. Simon Ecks commits crimes in order to drain enough energy that he can give his more brutish other side a physical body of his own.
- Adaptation Origin Connection: Double X is the cause of Firestorm's origins here, since it's his attack on a power plant that fuses Ronnie Raymond and Jason Rusch.
- Divergent Character Evolution: Doctor X and Double X looked identical in the comics. Here, Double X is much taller and more muscular.
- Evil Counterpart: To Firestorm. Both are two people technically stuck in the one body, one a scrawny nerd, the other a towering thug. The difference is that Firestorm's components learn to get along and work together. The Simons just hate each other.
- Evil Sounds Deep: Not so much with Simon, whose voice is more nasal than most of Perlman's usual roles. Double X's voice is a bit deeper than his, though.
General Kafka / Shrapnel
- Composite Character: General Kafka and Shrapnel are separate people in the comics.
- Create Your Own Villain: He was just an innocent villager in a farm town, which the GPA ruined. The survivors tried to rebuild, but Kafka only desired revenge on the GPA.
- Flechette Storm: As Sharpnel, he can endlessly shoot off pieces of his body. Batman and OMAC both note he doesn't seem to have any problem with conservation of energy.
- The Generalissimo: What he starts off as, a general of an unspecified county (with an eastern European accent).
- Genius Bruiser: It's hinted that his science experiments are his own creation, and as Shrapnel he's capable matching OMAC in a fist-fight.
- Red Eyes, Take Warning: As Shrapnel, his eyes glow red.
- That Man Is Dead: "Kafka is gone! There is only Shrapnel!" Man clearly knows the value of branding.
- Unwitting Pawn: Kafka is one of Equinox's pawns.
Harley Quinn (Dr. Harleen Frances Quinzel, M.D.)
A psychiatrist who worked at Arkham Asylum until she met the Joker and grew to love him, eventually becoming his accomplice and on-off sidekick. Harley is seen with the Joker at the antiques museum in "Emperor Joker!" when he is about to steal his memorabilia until Batman shows up. While both the Dark Knight and the Clown Prince of Crime fight each other, Bat-Mite comes along and falls for her. When Bat-Mite accidentally gives all his powers to the Joker in his attempt to help Batman, things start going to hell when the Joker recreates the universe in his own image and uses the Dark Knight as a cosmic punching bag by killing him repeatedly and bringing him Back from the Dead each time. At the same time, both she and Bat-Mite question their faith in their heroes, since the latter care more about each other, and the former wonder if they'd be "better off without [them]".
- All Women Love Shoes: She wears her high heels in this one.
- Bash Brothers: A rare case when she and Bat-Mite work together to stop Joker-Mite from killing off Batman, even when using her title cards as weapons.
- Blowing a Raspberry: She does this to one of the Joker's henchmen, even though she is rendered mute.
- Boyish Short Hair: Sometimes.
- Cute Mute: When she becomes magically silenced by the Joker. Of course, this is seen as a defiance of the trope.
- Dark Mistress: For the Joker.
- Deliberately Monochrome: Her appearance along with Joker's other henchmen; see Shout-Out below.
- Drop the Hammer: Even when she is Deliberately Monochrome, she never forgets that she is not afraid to use a mallet.
- Dumbass Has a Point: She warned Joker that going into Batman's mind could backfire on him.
- Gold Makes Everything Shiny: Her necklaces and bracelets, though they are Deliberately Monochrome.
- Impossible Hourglass Figure: And what a beauty Harley is with that figure.◊
- Improbable Weapon User: While she is silenced by the Joker, whenever she tries to say something, her title card appears for a few seconds. She and Bat-Mite use this to their advantage by using these title cards as weapons in order to stop Joker-Mite and the others from killing Batman.
- Little Black Dress: Her 1920s style black jazzy fringe flapper dress, right down to the knees.
- Not Wearing Tights: This version of Harley never dons her comics costume, making it hard to tell it is her from appearance alone.
- Shout-Out: She is modeled after silent film actresses of The Roaring '20s; plus, the title cards that appear whenever she tries to speak though she is muted date back to the silent films that lasted until the late 1920s.
- You Don't Look Like You: This version of Harley has the appearance of a 1920s flapper, wears no facepaint, and looks nothing like the female clown or jester one might expect of her.
The Injustice Syndicate
The greatest criminals of another Earth, the Crime Society assist Owlman in his villainous deeds.
- Adaptation Name Change: They are based on the Crime Syndicate from the comics.
- Adapted Out: While based on the Crime Syndicate, the Injustice Syndicate isn't shown to have Ultraman, Superwoman, Power Ring or Johnny Quick as members. Ultraman and Superwoman's absences are somewhat understandable, as the team appeared before Superman and Wonder Woman's restrictions from use were resolved.
- Archer Archetype: Blue Bowman.
- Color Character: Blue Bowman, Scarlet Scarab and Silver Cyclone.
- Creepy Monotone: Silver Cyclone speaks entirely without emotion, regardless of what he's saying, including his plans to torture Red Hood.
- Evil Counterpart: All of them are evil versions of the heroes, with evil versions of Green Arrow, Blue Beetle, Red Tornado, Atom, Aquaman, Plastic Man and Fire.
- Fantastic Racism: Silver Cyclone admits he hates all humans when the plan to nuke Batman's world goes awry, stating the bomb only affects organic tissue.
- No Name Given: The villainous Aquaman, Plastic Man and Fire don't get identified by name on the show
- Omnicidal Maniac: All of them have no problem wiping out an entire planet with a nuke as an example, but Scarlet Scarab, Blue Bowman and Silver Cyclone are the worst.
- Teens Are Monsters: Scarlet Scarab is the youngest member of the team, but every bit as evil and psychopathic as the others, getting gleeful at the thought of wiping out an entire planet, and gloating over having someone's heart in his closet.
- Villainous Friendship: Dyna-Mite states he considers Owlman a friend.
- The Voiceless: The Injustice Syndicate counterparts of Aquaman, Fire and Plastic Man never speak.
- Your Head Asplode: Silver Cyclone gets his head blown up mid-rant by the Red Hood.
The uncle of Ted Kord, the former Blue Beetle. Initially appearing as a friend to Jaime Reyes, Ted's successor, Jarvis turns out to be hiding sinister motives.
- Beard of Evil: A major distinction between him and the genuinely heroic Ted is his beard.
- Bitch in Sheep's Clothing: He initially pretends to be a nice, cheerful guy, but he uses Jaime as a pawn in his plan. He had previously done the same with Ted.
- Composite Character: With Max Lord, given both that his voice actor Tim Matheson voiced Lord in Justice League and that much like Lord in the comics, this version of Jarvis is responsible for the death of Ted.
- Hero Killer: It's his plans that caused Ted's demise.
- Mad Scientist: Using an alien doomsday weapon to create an army of invincible robots to take over the world.
- Walking Spoiler: The fact he's not Ted is a big reveal in his debut.
Once a lowly street hood, working for Gotham's biggest crime lord, Lew Moxon, a young Joe Chill was desperate to make amends for screwing up a job, and on his boss's orders went after one Thomas Wayne, and in doing so helped create the Caped Crusader.
- Accidental Murder: Killing Thomas Wayne was intentional. Killing Martha wasn't.
- Alas, Poor Villain: He murdered the Waynes and remained an unrepentant criminal for his entire life but his final moments can evoke some sympathy. After Batman confronts him, beats him down, and reveals that he was the young son of the couple that Chill murdered, Joe Chill became so distraught that he ran out and told the other villains that he was the one who created Batman to try to get their help... only for them to mercilessly attack him for creating the hero who locks them up night after night. After that, Batman finally shows up to save him and in the struggle, part of the building is destroyed with debris falling on top of Chill, fatally wounding him. In his final moments, Joe Chill manages to share some parting words with Batman, acknowledging that Batman had gotten him in the end, and finally accepts what had happened to him in the end was fitting.
- Create Your Own Hero: His killing of Bruce Wayne's parents is what led to Bruce Wayne becoming Batman.
- Karma Houdini Warranty: He killed the Waynes and ran off into the night, evading Bruce Wayne's attempts to find out who he was for years, while becoming a highly successful weapons dealer. Had the Spectre and the Phantom Stranger not gotten involved, he might never have learned the truth at all. Batman decides not to take vengeance on him, but then Chill is conveniently crushed by some falling debris anyhow. Not that the Spectre would know anything about that...
- Small Role, Big Impact: If it hadn't been for Joe, Bruce Wayne would never have become Batman. He's only in the one episode, but it's because of him the show happens at all.
- Too Dumb to Live: Revealing to a room full of Gotham's rogues you are single-handedly responsible for creating Batman... not a smart move.
Kalibak the Cruel
Darkseid's oldest son and the leader of the forces of Apokalips.
- Adaptational Badass: Most incarnations of Kalibak tend to be little more than a Jobber to Superman. This Kalibak, meanwhile, is the most threatening incarnation of the character to date, having defeated the entire Justice League single-handedly (which Superman was admittedly not a part of yet).
- Composite Character: Steppenwolf's role as Darkseid's Frontline General was given to Kalibak here.
- The Dragon: To his father, Darkseid.
- Hero Killer: Subverted. The teaser for "The Knights of Tomorrow!" shows The Question seemingly jumping to his death to escape Kalibak. "Darkseid Descending!" shows that he survived.
- Near-Villain Victory: He captures the Justice League and is prepared to execute them. If his parademon soldiers didn't squabble over who gets to take the first shot, he would have succeeded.
Kite Man (Charles Brown)
The former boss of Eel O'Brien in his criminal days, Kite Man is a crazed maniac obsessed with kites and Benjamin Franklin due to a childhood incident. His two desires are to be the most famous kite-related person ever, and to get revenge on O'Brien.
- Arch-Enemy: For Plastic Man. Fittingly, Plastic Man's arch-nemesis is every bit as ridiculous as the rest of his life.
- Broken Pedestal: He used to idolize Ben Franklin, but now considers him a fraud after the incident that gave him his kite obsession (he tried recreating Franklin's famous kite experiment, got zapped and went crazy).
- Evil Counterpart: Gains a version of Plastic Man's own powers, turning him into a dark version of Plas.
- Idiosyncrazy: A twofer: Kites and Benjamin Franklin.
- Irrational Hatred: Thanks to his childhood accident, he has a deep hatred for Benjamin Franklin.
- It's Personal: Eel O'Brien's greed was what caused Batman to arrest him, and then he identified Kite Man during his trial. Kite Man swore revenge on O'Brien and his loved ones.
- Large Ham: In fairness to him, he is insane.
- Never My Fault: When describing the incident that drove him insane, he glosses over his numerous safety hazards and blames Ben Franklin entirely.
- Not-So-Harmless Villain: Is much more sinister than most other portrayals, even trying to murder a baby. By contrast, Kite Man is usually shown as a harmless villain.
- Overly Narrow Superlative: He wishes to become the most famous kite-related person in history! Subverted when you realize that the current holder of that title is his former idol, Benjamin Franklin.
- Rhetorical Question Blunder: He asks what Ben Franklin ever accomplished. Plastic Man and Woozy both point out things he was responsible for.
- Shout-Out Theme Naming: Take a look at his theme, then take a look at his real name.
- Too Dumb to Live: "Long Arm of the Law" shows the incident that drove him insane, playing with a kite in a thunderstorm with metal braces while standing in a bucket of water.
K'rull the Eternal
A Neanderthal man who gained immortality from the strange light of a glowing red meteor, K'rull believes himself to be intrinsically superior to the mere humans who now rule the globe. He lives for the day when he can overthrow Homo sapiens and take his rightful place as ruler...and don't let his caveman look fool you, because he's more than smart enough to do it.
- Amazon Chaser: He likes how his henchwoman becomes more muscular.
- Composite Character: Of Captain Marvel villain King Kull and Vandal Savage, with a hint of Darkseid's son Kalibak.
- Genius Bruiser: Several thousand years have given him a lot of time to get some reading in. Though it doesn't mean he can't enjoy the fun side of particle colliders - smashing things into walls.
- Green Rocks: He got his immortality from a red meteorite.
- Karma Houdini: Since he's immortal, he'll never die of old age. A flashforward shows he'll still be around in the 25th century (though by then he does seem to have given up on overt evil).
- Names to Run Away from Really Fast: His name sounds like "cruel".
- Sharp-Dressed Man: By the 25th century, he's taken up wearing classy suits instead of dressing like a caveman.
- Who Wants to Live Forever?: He's immortal, so he outlived everything he's conquered.
Louie "Lew" Moxxon
A former high-ranking crime lord in Gotham when Bruce Wayne was a child, now elderly and infirm, but holding information the Dark Knight seeks.
- Arson, Murder, and Jaywalking: In-between mentioning all the legit criminal deeds he performed over the decades, he idly mentions he also once yelled at his wife.
- Disproportionate Retribution: Thomas Wayne thwarted his robbery attempt, so he decides to send a hitman to whack him. This turns out to be an extremely bad decision.
- Even Evil Has Standards: He was very specific to Joe Chill that only Thomas Wayne should be killed, if he was going to do it, and to at least make it look like an accident. He feels bad that Joe's screw-up left Bruce without a mom.
- Incurable Cough of Death: Whatever it is that's killing him, he's coughing in his scene and has minutes left by that point.
- My Sister Is Off-Limits!: Among his confessed deeds are admitting he beat up another kid in school for making a pass at his sister.
- Retired Monster: The head of Gotham's rackets, he seems to have spent out his life suffering no true long term consequences for his many misdeeds, dying relatively peacefully in his old age in a Gotham hospital.
- Small Role, Big Impact: He appears in one episode, but he's the guy who caused the death of the Waynes, and therefore responsible for Batman being Batman.
- Arch-Enemy: To Superman, naturally.
- The Bad Guy Wins: After he successfully defeats Batman in the episode "Triumvirate of Terror".
- Bald of Evil: Like most versions of the character, he is a bald superillain.
- Curb-Stomp Battle: Delivers one when he breaks into the Batcave, with his Power Armor designed to fight Superman proving more than a match for anything Batman has.
- Fat Bastard: Much chunkier than in previous adaptations.
- Gambit Roulette: Exposing Superman to Red Kryptonite. He gets what he wants (ruining Superman's reputation) and knew the effects would only last 24 hours, but it was quite a risk to have an out of control Superman running around.
- Man of Kryptonite: Relied on Kryptonite so much Superman no longer needs super vision to see it coming.
- Mythology Gag: Shares some of his DCAU counterpart's Ambiguously Brown-ness, and Kevin Michael Richardson does make him sound similar to Clancy Brown (who voices him in that continuity).
- Powered Armor: Built to fight Superman.
- Smug Snake
- Vitriolic Best Buds: With Joker and Cheetah.
Evil ruler of War World, he originally sought to use Jonah Hex as a way to beat batman once and for all, when that failed, he brought a War Moon to earth in an attempt to destroy the world, while also humoring its heroes and villains with a race to see if he'd do it.
- Adaptational Wimp: Batman and Jonah Hex went up against him in this show and survived. In the comics, Mongul is roughly equal to Superman in strength, and would have crushed them both easily.
- Bond Villain Stupidity: Who would teleport losing racers to a cell rather than let them die? He does ensure the prisoners are separated from their various tools and trapped behind forcefields, but he foolishly never considered that Batman and Green Arrow would anticipate that.
- Composite Character: Is a mix of both Monguls, being the ruler of Warworld like the original, but the rivalry with Mongal comes from his son.
- I Lied: Said verbatim in "Death Race to Oblivion".
- Lantern Jaw of Justice: Well, it is a big chin.
- Rogues' Gallery Transplant: Normally a Superman villain, whose screen time is spent fighting Batman. Superman isn't even referenced in any of his appearances.
- Sibling Rivalry: With his sister, Mongal.
- Wowing Cthulhu: He is impressed by Batman's ruthlessness in the Death Race and eliminating all the competition. He also praises Green Arrow for the time it took for him to recover from his car being damaged.
Morgaine Le Fay
Medieval witch. Arthur's sister. You may have heard of her. Enslaved Etrigan in Arthurian times to help take over Camelot and kill Merlin.
- Adaptational Attractiveness: The comic version of Morgaine (as well as her counterpart in the Justice League cartoon) has to wear a mask and armor to hide her hideously decayed face. In this show, she's downright gorgeous. Justified since this is supposed to be during her early years.
- Breath Weapon
- Cain and Abel: She's the Cain to Arthur's Abel, overthrowing his kingdom.
- Composite Character: She takes on a bit of Nimue, Merlin's student who betrayed him.
- Evil Brit: Fitting since she is a figure of Arthurian legend.
- Expy: Is almost identical to Disney's Maleficent, both being powerful evil witches obsessed with gaining power who magically transform into dragons to fight the heroes, even both dying from being stabbed in the stomach by a magical sword while in dragon form.
- Femme Fatalons: Which are capable of scratching through stone.
- Public Domain Character
- Scaled Up: She turns into a dragon to get rid of Jason Blood, Batman and Green Arrow.
- Taken for Granite: Her favorite method of dispatching an enemy. Even her dragon fire turns folks to stone.
- Batman Gambit: He constructs a ray that he tells everyone is a Death ray, and anticipates Dr. Sivana betraying him and using it on him. So he intentionally made it a Growth Ray that turns him into a monster.
- Big Creepy-Crawlies: He uses the growth ray to turn himself into one.
- Big "NO!": He does not take well to being defeated by a baby.
- Bond Villain Stupidity: A fairly tame version. He cannot help taunt the Baby Batman after all signs show he is completley helpess to defend himself, but given it's Batman he still had a trick up his sleeve.
- The Chessmaster: Masterminds taking over the Monster Society, turning the Marvels against one another, tricking the villains to building a growth ray for him, and even anticipates Sivana betraying him and using said ray on him which was All According to Plan.
- Evil Gloating: He simply cannot risk taunting the Baby Batman, which leads to his downfall.
- Manipulative Bastard: He uses mind tricks to turns the Marvels against each other, and plays Dr. Sivana like a fiddle.
Mrs. Manface (Manfreda Donatella)
Manfreda Donatella Face is the wife of Babyface. She has the face of a square-jawed man (complete with a five o'clock shadow), but the voice and body of a normal woman.
- Battle Couple: With Babyface.
- Butter Face: It's all in the name.
- Canon Foreigner: Like Babyface she was created specifically for the show.
- Lady Looks Like a Dude: She's meant to look like a cross-dressing man.
- Perma-Stubble: She has a five-o-clock shadow to make her face look all the more masculine.
- Unholy Matrimony: Married to fellow criminal Babyface.
The Music Meister
Picked on at school for being in choir, he eventually discovered that he could control people's minds using his singing voice. What results is quite possibly the greatest Musical Episode of anything ever.
- Breakout Villain: Despite being a One-Shot Character, he's become one of the most well-known characters from Brave and the Bold, enough to give him a silent cameo in the ending of the series, as well as show up in other DC properties, being a recurring character in the Arrowverse (albeit heavily reworked), and becoming a playable character in the LEGO Batman video game series starting with 3.
- Camp Straight: He has a musical theme, Unlimited Wardrobe of ostentatious outfits, an openly gay voice actor—and a Villainous Crush on Black Canary.
- Canon Foreigner: Has no comics counterpart, though he did end up as a villain on Arrowverse's Supergirl (2015) and The Flash (2014).
- Card-Carrying Villain: Proclaims himself to be "the maestro of villainy".
- Changing Clothes Is a Free Action: He goes through around a dozen costumes, including eight in a single extended scene.
- Compelling Voice: A compelling singing voice. He doesn't even have to exactly sing the commands. He just has to sing, and people fall into step. His debuting scene shows that he's even able to do it with music as the assembled heroes and villains start slipping into his trance before he's even revealed himself.
- Evil Redhead: He's a red-haired villain.
- Freudian Excuse:
- Bullies used to pick on him because he sang in choir, but something very strange occurred when he kept singing higher. The ruffians around him quickly fell into a trance, and it was then, with wicked glee, he made those puppets dance!
- Also, his initial Villain Song continually mentions him "settl[ing] the score."
- Instant Costume Change: It may very well be one of his superpowers. He has a notorious habit of changing outfits midbattle.
- Large Ham: As the Big Bad of a musical episode, what else could he be?
- Love at First Note: With Black Canary after hearing her sing solo in the Cold Open (even when she knocks him flat with her sonic screaming) but when she rejects him for Batman, he attempts to dispatch her.
- Making a Spectacle of Yourself
- Mad Artist: He's a great singer, who takes "wicked glee" in using his hypnotic voice to control people into doing big (and lethal) music numbers while they steal or fight heroes for him. He's also shown playing to an audience of cardboard cut-outs at one point.
- The Music Meister: The proud Trope Namer.
- Musical Episode: Instigates one.
- Musical World Hypotheses: The musical episode is explained by him having spontaneous musical numbers as an explicit super power.
- Mythology Gag: Neil Patrick Harris is credited as a "Special Guest Villain" for his debut episode.
- Psychic-Assisted Suicide: "Now that Batman's been delayed/Your usefulness has passed/A distraction is what I need/So kick into that blast!" (Of course, Batman saves them.)
- Squishy Wizard: As difficult as it is to fight him due to his Mind-Control Music, it only takes Batman a single punch to knock him out.
- Tenor Boy: It's obvious that the Music Meister is a pretty young tenor.
- There Is No Kill Like Overkill: His Death Trap. Did they survive the Frickin' Laser Beams, the water cannons loaded with acid and the pendulum blades? Now The Walls Are Closing In before a Trap Door opens to an Acid Pool. Let's also have a Time Bomb just in case. When your prisoners are Batman and Black Canary, this is, of course, Bond Villain Stupidity at its finest.
- Unlimited Wardrobe: He switches through several outfits throughout his episode that signify different musical eras.
- Villain Song: Every song he sings.
- Wing Ding Eyes: His eyes and glasses are two musical notes.
Ocean Master / Orm of Atlantis
AQUAMAN's half-brother, who has had to live in his brother's shadow ever since their mother made Arthur king of Atlantis. He used to be a villain, but has now gotten over that. Really...
- Adaptational Heroism: While he's still a scheming fiend out to take over Atlantis, he's often depicted as straightforward evil, especially in Justice League. This version genuinely cares about his homeland, to the point where he teams up with Arthur to save it from Black Manta.
- Adaptational Ugliness: Comic Orm is conventionally attractive. This guy's been hit with an ugly stick, just so we know he's clearly bad news.
- Cain and Abel: To AQUAMAN.
- Easily Forgiven: He does help thwart the scheme he helped start, making it look like this is in effect. Then it turns out he's not that easily forgiven. First, Arthur's gonna read him some of those memoirs of his. Harsh.
- Even Evil Has Standards: He wants to rule Atlantis, not destroy it like Black Manta does.
- Good Scars, Evil Scars: Has a scar going under his right eye.
- Horrible Judge of Character: Orm assumed Black Manta was trustworthy. His brother doesn't even finish saying Manta will betray him before Black Manta betrays him.
- Obviously Evil: Which Batman tries fruitlessly to point out, but AQUAMAN is having none of it. To be fair, he isn't completely evil.
- The Resenter: Mommy named Arthur king, so Orm has tried many times to kill him and take the throne.
A Germanic mad scientist who once fought the JSA, long ago, going missing when the first Black Canary damaged his equipment, only returning in the modern day and age thanks to a loyal flunky.
- Badass Normal: Has no superpowers, but still overpowers the Justice Society as soon as he's released, and even has Batman's number in a fistfight.
- Composite Character: He takes over Hitler's role of the Spear of Destiny's wielder from the comics.
- Curbstomp Battle: Delivers one to Wildcat.
- Hoist by His Own Petard: Gets zapped with his aging staff, turning him into an old man after having aged the JSA and Batman with it already.
- No Swastikas: He's got a German-accent, and took part in some kind of military conflict which America was a part of many decades ago, but his political and national associations go distinctly unmentioned.
- Too Dumb to Live: Trying to use his staff even after Black Canary had damaged it with her Canary Cry. Both times, in fact.
The Planet Master
A supervillain with the power of all the planets of the Solar System (and yes, that includes Pluto).
- Berserk Button: Don't mention Pluto's status as a dwarf planet. He's sensitive.Blue Beetle: News flash: Pluto isn't considered a planet anymore.
Planet Master: INSOLENCE!
- Chest Insignia: It changes to match the planet he's channeling the power of.
- Dishing Out Dirt: Saturn's power gives him the ability to move rocks with his mind. He uses them to make a rock buzzsaw.
- An Ice Person: Pluto's power.
- Super Speed: The speed of Mercury.
- Super Strength: The strength of Jupiter.
- Uranus Is Showing: Jamie assures AQUAMAN he doesn't want to know what power Uranus grants.
Poison Ivy (Pamela Isley)
Known by her real name Pamela Isley, Poison Ivy's work deals with flowers and all things plant, including a giant venus flytrap named Georgia that she once fed Batman to because he refused to marry her.
- Affably Evil: To help balance out her Fiery Redhead temperament.
- Amazon Brigade: The Flower Children, who follow her orders.
- Ambiguously Gay: Her Amazon Brigade with her Flower Children and the fact that she leads an all-female team (and her friendship with Harley Quinn) could be hinting at signs of this trope.
- Ambiguously Bi: Although she does seem interested in making Batman her mate.
- Beauty Is Bad: This trope goes without saying.
- Berserk Button: Joe Chill begging for mercy. Finding out that one of her Flower Children is Black Orchid in disguise is another.
- Determinator: In the episode "The Mask of Matches Malone" after taking a headbutt from Batman she gets back on her feet and tangles Batman up in roots before reclaiming her thorn spear. Before it looks as if Poison Ivy is about to win for once, Black Orchid flies towards Poison Ivy and knocks her out before disappearing mysteriously.
- Did Not Get The Guy: Batman turns her offer down to become her king.
- Does Not Like Men: After Batman rejects her in the teaser in "The Mask of Matches Malone"
- Femme Fatale: Just like Catwoman, she too uses her charm and beauty to her advantage.
- Fiery Redhead: Oh yes very much so.
- Long Bus Trip: After her appearance in the episode "The Mask of Matches Malone", she doesn't appear again until the season 3 finale episode "Mitefall", where just like every other character present makes a background cameo.
- Plant Theme Naming: They don't call her Poison Ivy for nothing after all.
- Composite Character: In the comics, Professor Zee was a victim of Degaton's whom he stole his time machine from.
- The Dragon: For Per Degaton.
- Gadgeteer Genius: Anticipating Degaton would want an army when he was restored, Zee went ahead and built him a new one.
- This Is Gonna Suck: He was pretty confident his tech would let him have the one-up on the equally elderly Wildcat... until Ted got zapped back to his physical prime.Wildcat: Let's dance, pointdexter.
Zee: Aw, nerts.
Professor Zoom (Eobard Thawne)
The yellow-clad Evil Counterpart to the Flash, Eobard Thawne is a criminal who hails from the 25th century. His mission is to destroy his lawful nemesis and all that the Flash stands for.
- Adaptational Nice Guy: Believe it or not, this version of Eobard Thawne actually manages to be one of the least nastiest versions of the character yet. Unlike the comics version or the DCAMU version who are notorious Serial Killers, this Thawne merely imprisons the Flash to siphon his speed, and is otherwise content with ruling the future as his own kingdom.
- Arch-Enemy: To the Flash.
- Casting Gag: Eobard Thawne the Arch-Enemy of Barry Allen, is now played by Barry Allen himself.
- Composite Character: He's ostensibly Eobard Thawne (Reverse-Flash I/Zoom I) in his antagonism to Barry, his mask is that of Hunter Zolomon (Reverse-Flash II/Zoom II) with the black-and-red eyes. He also has speed minions who get their speed from a machine that is powered by a captured speedster which is taken from Savitar.
- Curb-Stomp Battle : One of the few villains from the series that Batman can't defeat on his own, even after the hero gets temporary super speed. Zoom would have killed Batman if the Flash hadn't intervened.
- Evil Overlord: Of the 25th century, in "Requiem for a Scarlet Speedster."
- Gadgeteer Genius: He was able to create a device that siphoned the previously-thought-to-be-dead Flash's speed into arm-bands that powered his private army and exponentially increased his own speed.
- Knight of Cerebus: While Lighter and Softer compared to his comic incarnation, he is still a villain who successfully got the better of his Arch-Enemy, and has been torturing him while using him as a power source. He nearly kills Batman using the same method he is known for in the comics; phasing his hand into the victim's body.
- Mad Scientist: Has inventions that allow him to gain the same powers as the Flash, while also giving them to his minions.
Psycho-Pirate (Roger Hayden)
Gaining powers off of others' fears, Psycho Pirate lures his victims into traps that will leave them reliving their worst nightmares so he may feed off of pure fear.
- Adaptational Jerkass: A much eviller version of Psycho Pirate, who gets a kick out of Mind Rape.
- Adapted Out: No mention of his Medusa Mask is made.
- Emotion Eater: He eats anger.
- Hate Sink: While most of this show's villains have too much flair and charm to really hate, Psycho-Pirate sticks out as truly loathsome. He's a smug predator who relishes tormenting his young victims, and clearly thinks himself superior to Batman, despite being nowhere near as powerful or competent as he thinks.
- In Name Only: He's so different he could very well be a new character.
- Mind Rape: How he gets the emotions he craves.
- Paper Tiger: Psycho-Pirate is only a threat based on how much he's gotten into your mind. In the real world, he's just a slimy little bully who goes down with one punch.
- Smug Snake: He loves rubbing it in how untouchable he is as long as he's plugged into the Outsiders' mind, and within the mental realm he manifests as a more powerfully built masked figure, reflecting his abnormal ego. It's pretty satisfying when Batman punches him out like the spineless creep he is.
- Soft-Spoken Sadist: He never raises his voice, even as he's doing his best to psychologically drain a group of teenagers.
- Would Hurt a Child: Or a pack of super-powered teens.
Punch & Jewelee
A pair of acrobatic, clown-themed criminals.
A well-intentioned villain who wants to protect nature... by destroying human civilization. Despite his views on nature, he's rather old fashioned when it comes to his daughter Talia, feeling that a woman is incapable of succeeding him.
- Disney Villain Death: Appears to be the case at the end of "Crisis, 22,300 miles above Earth".
- Heir Club for Men: Talia just isn't good enough to be his heir, purely due to her not being a male
- Icy Blue Eyes: His eyes are a very noticeably pale blue.
- Offing the Offspring: For her betrayal in helping Batman in "Crisis, 22,300 miles above Earth". He might have also been looking for an excuse to get rid of her since she's a woman.
- Powered Armor: He wears one in "Crisis, 22,300 miles above Earth".
- We Can Rule Together: He offers the position of his heir to Robin, who declines.
- Well-Intentioned Extremist: As with most versions, he's an Eco-Terrorist that wants to depopulate humanity to preserve the planet
- Worthy Opponent: In the comic "Batman Dies at Dawn", he agrees to let the Robins use the Lazarus Pit to save Batman, because he deserves a better demise than just some thug shooting him (though he does neglect to mention the side-effects of the Pit).
A m-genius scientist on the planet Zur-En-Arrh, and arch-enemy of that world' Batman, the short-tempered Rohtul is determined to show the whole world how great his mind is, by stomping it flat. Just after he gets rid of that meddling Batman, first.
- Actor Allusion: As he is voiced by the very same man who once voiced the DCAU's Lex Luthor, this trope naturally goes without saying.
- Awesomeness by Analysis: Manages to work out how to disable Batman's powers, simply by deducing his likely point of origin.
- Bald of Evil: He's based on Luthor after all.
- Cardboard Prison: Apparently Zur-En-Arrhian authorities don't bother searching the supervillains they lock up, so he's able to summon one of his robots to bust him out the minute he gets bored.
- Expy: He is quite blatantly the Silver Age Lex Luthor, right down to being voiced by someone who'd voiced him previously.
- Mad Scientist: Being an expy of Luthor, it's a given.
- Meaningful Name: Just to drive the point home, his name is Luthor, reversed.
- Robot Master: Commits crimes aided by an army of giant robots.
An adversary of Plastic Man's, this latex leviathan may not be very bright, but his rubbery nature makes actually knocking him down a difficult prospect.
- Canon Foreigner: Has no counterpart in the comics.
- The Dragon: He works for Kite Man.
- Dumb Muscle: He's a brutish henchman to Kite Man who also happens to be very stupid.
- Evil Counterpart: Clearly created to be one for Plastic Man, with his rubber gimmick contrasting Plastic Man's, uh... plastic gimmick.
- Implacable Man: Being made of rubber, punching him isn't really going to work, since he can just bounce back.
- Simpleton Voice: He has a deep, silly voice to emphasize his moronic nature.
A hostage turned partner in crime to Cavalier, Ruby Rider first appears in the episode "Bold Beginnings!" during Green Arrow's story segment.
- Bait-and-Switch: She does this to Batman and Green Arrow after Cavalier appears and her true colors are revealed. Shortly after that, her and Cavalier tie Batman and Green Arrow to a stake as Cavalier tosses a torch at the logs before making his getaway but not before mocking Batman and Green Arrow by calling them the charred crusader and burnt bowman respectively.
- Bitch in Sheep's Clothing: She puts on this act to get Batman and Green Arrow to save her, only to reveal she didn't need saving and that she was Cavalier's partner in crime all along.
- Disproportionate Retribution: Much like her partner in crime Cavalier, she too has no problem with leaving Batman and Green Arrow for dead.
- Evil Cannot Comprehend Good: It's only after her actual intentions are revealed that this starts to become obvious to Green Arrow and Batman.
- Inksuit Actor: She's an exact look alike of her voice actress right down to the hair length and color.
The Green Lantern of Sector 1417, considered the most peaceful of all sectors in the known universe. However, during the fight against Despero, Sinestro shows his true colours when he turns against the Corps.
- Bitch in Sheep's Clothing: He initially seems like just another Green Lantern, even allowing Batman to assist when Guy tells him to get lost. Then it turns out that he took over his own world, and decides to kill Mogo as plan A. While beating up Guy, he even declares he thought himself better than the other lanterns.
- Obviously Evil: With a name like that? And yet Batman completely trusts him until Despero reveals what he did.
- Sealed Evil in a Can: After kicking his butt, Guy seals Sinestro away inside his ring.
- Shoot the Dog: While Batman goes after Despero, Guy finds Sinestro setting bombs all around Mogo, preparing to kill him, on the grounds it's safer than letting Despero keep controlling him... and because he doesn't trust G'nort to succeed.
- Truer to the Text: Past animated versions of Sinestro fulfilled their basic function of being Green Lantern's power hungry Arch-Enemy, albeit without too much backstory. But this incarnation was the very first version of Sinestro where he was explicitly portrayed as being a Knight Templar who believed in order at all costs, even if it meant he had to impose his will on an entire planet as its dictator, just like his comic book counterpart.
- Villain Has a Point: He's definitely evil in trying to kill Mogo, another sentient being without even trying to look for an alternative, but given Batman's plan relied on G'nort saving them, it's not hard to see why Sinestro had little faith in it, given G'nort's a complete idiot who only just remembers the Green Lantern oath at the last minute (and that's with a cheat sheet).
- Canon Foreigner: Created exclusively for the show, though he does share similarities to New God Sleez.
- Unholy Matrimony: Married to the Tigress, with a pre-teen daughter, also a supervillain.
- Villains Out Shopping: AQUAMAN spots him driving down a freeway while on vacation. His glee at the thought of a potential plot to thwart is dashed when he sees Sportsmaster is also on vacation with his wife and daughter... and from the looks of it, they're having about as much fun as AQUAMAN'S having on his.
- The Voiceless: Doesn't say a word in "AQUAMAN'S Outrageous Adventure".
Mongul's champion, and primary underling.
- Adaptation Relationship Overhaul: In the comics, he was Darkseid's minion rather than Mongul's.
- The Dragon: For Mongul.
- You Have Failed Me: After losing Mongul's death-race, he's zapped, and told he's no longer Mongul's champion.
- Adaptation Relationship Overhaul: In the comics, Takeo's motive was to Murder the Hypotenuse, his brother Makeo, for marrying Katana. Since Katana is de-aged to a teenager, Makeo is Adapted Out, and Takeo instead kills Tadashi.
- Ambiguous Situation: His appearance is only in Katana's memories, fueled by guilt being egged on by Psycho-Pirate, and Batman claims she's misremembering what went down.
- Karma Houdini: Katana's flashback never specifies if she managed to avenge her master's death at his hands.
Ra's al Ghul's daughter, she wants to be his heir and feels threatened by his interest in Robin. So far she doesn't appear to return Robin's attraction to her.
- Daddy's Little Villain: Lacks the innocence some of her other incarnations have, though that doesn't make her totally loyal to Ra's. The fact that her dad prefers a male heir may have something to do with it.
- Dating Catwoman: Robin was hoping for this, but is quickly shot down, though it's because she's only interested in Batman.
- Dual Wielding: She dual-wields a pair of knives in a fight.
- I'll Kill You!: Tells Robin that if she sees him again after freeing him, she'll destroy him.
- Inadequate Inheritor: Ra's knows just how skilled she is, but would still prefer a male heir. He tells Robin this while she's in the same room.
- Mad Scientist's Beautiful Daughter: She's the beautiful daughter to an Eco-Terrorist.
- Mistreatment-Induced Betrayal: She decides to work against her father when he considers her unworthy of being his heir due to her gender.
- Spy Catsuit: Actually more coverage than she often has in her other depictions.
- Technicolor Eyes: Has purple eyes.
- What Happened to the Mouse?: She was last seen running off when Batman fights her father in the climax of "Crisis, 22,300 miles above Earth". It's unclear if she ends up taking over her father's organization following his apparent death.
The Terrible Trio
Fox, Shark, and Vulture are bored millionaires who become martial artists that wear masks of the animals they represent. As members of the Shadow Clan, they plan to steal the Wudang Totem from its respective temple.
- Adaptation Origin Connection: "Return of the Fearsome Fangs!" has flashbacks that depict them training alongside Batman and Bronze Tiger prior to Bruce Wayne becoming Batman. While Bruce and Ben Turner are martial artist in the comics, the Trio aren't and Bruce and Ben didn't train together.
- Adaptational Badass: This version of the Trio are skilled martial artists who trained alongside Batman and Bronze Tiger.
- Arrogant Kung-Fu Guy: Especially Fox.
- Drop the Hammer: Shark.
- Dual Wielding: Vulture.
- Master Poisoner: Fox.
- Big Ol' Eyebrows: As the Tyrant, he gains a pair of large eyebrows that go beyond his head.
- Blow You Away: Same as Red Tornado, he generates bursts of wind.
- Crazy-Prepared: Red Tornado built in a failsafe system just in case. Champion saw this coming, and had it removed.
- Easily Condemned: It takes precisely one tantrum for Batman to declare Champion is utterly irredeemable and needs to be destroyed forever.
- Fantastic Racism: On the giving and receiving end.
- Giving: He's not impressed with Batman even before he gets emotions, dismissing him as an organic lifeform. He gets worse once he gets emotions.
- Receiving: Police get hostile with him just for being a robot.
- High Collar of Doom: As the Tornado Tyrant, he gives himself a large popped collar.
- Horrifying Hero: Spooks a pair of children he's trying to save due to his robotic appearance and behavior.
- Humans Are the Real Monsters: Comes to believe this.
- Hypocrite: For all his hatred of humans, he acts far more human than his father.
- Killed Off for Real: His father blows him to pieces, and then melts those pieces just to be sure.
Two-Face (Harvey Dent)
Once Gotham City's DA Harvey Dent, his face got scared and his personality was split. Half good, half evil. His coin decides what the two personalities do. Batman hopes he can be reformed because Harvey was a good friend of Bruce Wayne's.
- Combat Pragmatist: Fair's good... But guns are better!
- Enemy Mine: Manages to be both the guest hero and the villain of his debut teaser after his mooks question the results of sparing Batman after a coin toss.
- Even Evil Has Standards: He will stay true to his coin toss. If it says a person lives, they live.
- Eviler Than Thou: Lost to Matches Malone. Actually Batman with Amnesia.
- Green and Mean: His "evil" side.
- Guns Akimbo: And he keeps a couple of spares.
- Pungeon Master: The number two comes up once or twice when he speaks."Two-bit punks! Think you can double-cross Twoface?"
- Two-Faced: After all, he is the Trope Namer. In this version, his left side is green.
The Weeper (Mortimer Gloom)
An elderly has-been supervillain who originally terrorised Bulletman. After botching his big opportunity to completely destroy Fawcett City many decades ago, he served hard time and retired completely from all criminality... at least, until the Joker discovered him and vowed to help bring him back into the villain game.
- Becoming the Mask: He admits that his mewls were originally part of the gimmick, but ever since his biggest plan was foiled by his own split second of hesitation, he's just shed "bitter tears of regret".
- Catchphrase: "How sad it is".
- The Eeyore: His whole gimmick is constantly crying and looking morose even when plotting dastardly capers.
- Evil Old Folks: Noted to be the first villain (in this show's universe, at least) to use a signature motif in all of his heists, inspiring countless costumed criminals the world over including the Joker himself. Although in the flashback, he looks just as old in the '40s as he does now.
- Faux Affably Evil: Although the Weeper may seem nice and docile, keep in mind that he was inches away from destroying an entire city before he was captured. He was also willing to get rid of the Joker to become Gotham's biggest criminal, but Joker admits he would have wanted that to happen as his greatest prank.
- He's Back!: Seeing Batman's surveillance machine on the news inspires him to return to villainy.
- Improbable Weapon User: His signature weapon is a wet handkerchief that he can somehow shape into a sharp blade.
- Odd Friendship: You wouldn't think that the Duke of Downers would get along so well with the Mountebank of Mirth, yet the Weeper and the Joker form a Villainous Friendship almost powerful enough to bring down Batman. The Joker lampshades the ironic perfection of it, especially since he decided to become a Monster Clown in response to the Weeper's defining gimmick.
- Red Baron: Known in his heyday as the Crying Crime King and the Duke of Downers among other grandiose monikers.
- Rogues' Gallery Transplant: Originally an enemy of the obscure Golden Age hero Bulletman, but he teams up with the Joker to fight Batman in his starring episode. (Bulletman also appears in a Lawyer-Friendly Cameo.)
