Rupert Thorne was a criminal overlord who resided in Gotham City.
- Adaptational Badass: Thorne is a much more powerful figure than in the comics as he's one of the few mob bosses still around after the "freaks" took over Gotham. See Composite Character.
- Art Evolution: Subverted. Thorne received a relatively minor redesign from B: TAS to Batman: Mystery of the Batwoman. Aside from losing weight and being streamlined, the character looked more-or-less the same as his B:TAS look.
- Big Bad Ensemble: While not on the same level as the Joker or Ra's al Ghul in this regard, Thorne is the series' most prominent white collar criminal. Notably, he is directly responsible for Two-Face's creation and he hires Bane in an attempt to have Batman killed, sparking the former's antagonism towards and obsession with the latter. His criminal empire takes a large portion of the series's run to topple.
- Bullying a Dragon: His attempt at blackmailing Harvey Dent, even though he knew that Dent had a violent temper stemming from his mental issues and was a large, strong adult who had barely been able to restrain himself from ripping one of Thorne's goons to pieces.
- Composite Character: While Thorne had connections to the mob in the comics, his role here as an untouchable mob boss is more in line with Carmine Falcone or Salvatore Maroni. He also fills the latter's role of causing Dent's disfigurement and transformation into Two-Face.
- Deadpan Snarker: He has his moments, such as when Batman crashes through his greenhouse window:"You'd better have the money to pay for that."
- The Don: The most powerful mobster in Gotham city at the start of the series. His old-school methods provide a contrast to those of Batman's more colorful foes.
- Even Evil Has Loved Ones: While he didn't make life easy for his brother Matthew, he still genuinely cares for him.
- Even Evil Has Standards: When Stromwell's son goes missing and he accuses Thorne of being behind it, Thorne points out that he never goes after a person's family. Thorne is actually planning to kill Stromwell right then, betraying him at a peace summit, but he is legitimately shocked at the accusation and is completely sincere in his assertion of innocence.
- Fat Bastard: He's very round.
- Faux Affably Evil: He likes to make himself appear pleasant, but he has never been shown to harbor good intentions.
- Hoist by His Own Petard: In his attempt to bring down Harvey Dent, he created his worst nemesis Two Face - who threatened his businesses, turned his books over to the authorities, and nearly killed him.
- Hypocrite: That Even Evil Has Standards moment above would have been more effective if the previously-produced episode before that one hadn't shown him using Harvey Dent's fiancée to get at Two-Face. Possibly via Loophole Abuse, as Grace had only been engaged to Harvey and thus wasn't technically part of Dent's family yet.
- Karma Houdini: Whilst defeated by Batman on a regular basis, being arrested doesn't seem to mean that much to him.
- Mood-Swinger: For all his suave attitude, he loses his temper very easily. A good example of this is towards the end of The Man Who Killed Batman.
- Not Me This Time: It's Never Too Late (as far as Stromwell's son is concerned), Vendetta and Second Chance.
- Pragmatic Villainy: At times.
- Sibling Yin-Yang: Smug, ruthless mobster whose brother is a morally troubled, yet sympathetic, disgraced surgeon.
- Villain Has a Point: When threatening to share Harvey Dent's psychiatric file with the press, Thorne sarcastically quips that the people have a right to know who they're electing for office. Not that Thorne really cares, and he deliberately made the situation worse, but this is actually a pretty valid concern: Would you vote for someone if you found out they've been desperately trying to sweep their violent dissociative identity under the rug?
Roland Daggett was a business entrepreneur. His company competed with Wayne Enterprises, which left Daggett resorting to dubious schemes to gain the competitive edge.
- Asshole Victim: Almost became this in the hands of Clayface and later Catwoman.
- Canon Foreigner: He was created for the series.
- Corrupt Corporate Executive: Deconstructed; in each of his four appearances, Dagget gradually loses his fortune as legal fees and criminal charges catch up to him.
- He finally faces jail time after his fourth appearance and is not seen again afterwards.
- Evil Counterpart: To Bruce Wayne.
- Evil Redhead: Though this one doesn't wear green.
- Icy Blue Eyes: Depending on the artist.
- Ink-Suit Actor: Does have a resemblance to his voice actor Ed Asner.
- Jerkass: He doesn't seem to have any qualms with ruining other people's lives just to get what he wants, as shown in his first two appearances.
- Karma Houdini: "Appointment in Crime Alley" — Batman is able to stop his scheme and capture his mooks, but not pin the dirty deeds on him.
- Subverted in Batgirl Returns when by that time, his failed schemes have left him so in the red, he is forced to steal a priceless artifact for money. When that and his attempt to kill the Bat Family fail, he goes to jail.
- Kick the Dog: His part in turning Matt Hagen into Clayface.
- Kill the Poor: His scheme in Appointment in Crime Alley.
- No-Nonsense Nemesis: Does this in "Batgirl Returns." After capturing Catwoman and Batgirl, this conversation takes place.Batgirl: So what are you going to do? Leave us hanging over one of these vats with acid burning through the rope?
Dagget: *Evil Laugh* If there's one thing I learned over the years, it's that you crime fighting types are very resourceful.
- Poison-and-Cure Gambit: In Cat Scratch Fever, he has stray animals infected with an incredibly virulent new strain of rabies that he plans to sell the cure for.
- Villain with Good Publicity: It doesn't last.
- Would Hurt a Child: He tries to destroy an inhabited neighborhood in his second appearance, and it's later shown that some of the residents were children.
Doctor Milo was an unscrupulous scientist who eventually joined Cadmus.
- Asshole Victim: In Justice League, he has a grudge against Amanda Waller, his employer, and releases Doomsday to get revenge. He only lives a few seconds after that.
- Back for the Dead: His surprise appearance in JLU ended very, very badly for him.
- The Dog Bites Back: It always backfires on him... Even when he's the dog.
- Evil Genius: He made a living of it.
- Evil Is Not a Toy: After being drafted into Cadmus, he tried to wheedle Doomsday into assisting him in destroying the organization from within. Doomsday didn't cooperate.
- Mad Scientist: Well, an evil scientist for hire.
- Poison-and-Cure Gambit: Had a key part in Roland Daggett's plan to do this in Cat Scratch Fever.
- Psycho for Hire: Always been shown on a payroll. He's essentially the scientist for hire in the Gotham underworld.
- Sinister Schnoz: He's a close second to the Penguin in that department.
- Too Dumb to Live: For such a gifted biochemist, he has a real tendency to ignore basic safety precautions. He was badly injured after deliberately triggering Anthony Romulus' lycanthropy, and a few years later was foolish enough to convince himself that Doomsday was a useful ally.
Hugo Strange was a corrupt scientist who discovered Batman's secret identity.
- Adaptational Wimp: He's far less menacing and dark compared to his other incarnations.
- Bald of Evil: Balding.
- Beard of Evil: To cement his appearance as a Freud stereotype psychologist.
- Big Bad Wannabe: For the one who discovered Batman's identity, he's outed of the spotlight quickly once the Joker and co. enter the scene. His scheme also falls apart rather quickly when he's manipulated, and the Joker quickly puts him in his place.
- Blackmail: He ran a clinic for the wealthy and powerful where he had a machine that let him read the minds of his patients, allowing him to dig up their darkest secrets and shames and later force them to pay for his silence. When Bruce checks in undercover he discovers he is Batman, but decides to have an Auction of Evil with Penguin, Two-Face and The Joker as the bidders. Adapted from the Pre-Crisis story where Strange first finds out Bruce is Batman, except blackmail had nothing to do with that one.
- Evil Is Not a Toy: Turned out that inviting Gotham's worst criminals wasn't such a good idea.
- Mental Picture Projector: His machine, which he uses to blackmail people.
- Overshadowed by Awesome: He arguably failed to make an impression due to be surrounded by far more colourful villains, most notably a Joker at his hammiest.
- Psycho Psychologist: A little different from most incarnations. He's still evil, but motivated mostly by greed, using a device to read the minds of his patients and then use the dark secrets he learned to blackmail them.
- Scary Shiny Glasses: A trademark of the character.
- Smug Snake: Turning his facility into a blackmail tool, and then bragging about how brilliant it was, might not have been such a good idea.
- Sunglasses at Night: The coloring of his glasses makes it look like shades.
- Villain with Good Publicity: Didn't last long, though.
- What the Hell Is That Accent?: A part of his stereotypical Freud-like persona.
Red Claw was an international terrorist.
- Affirmative Action Girl: And painfully bragging about it.
- Appeal to Force: Her schemes revolves holding cities for billion dollar ransoms with the WMDs that she steals.
- Amazonian Beauty: She has a very strong and muscular body, and it looks gorgeous!
- As Long as It Sounds Foreign: She had an unspecific, vaguely "European" accent. Where she and her terrorists came from is not elaborated on, except that they were not locals.
- The Baroness: A middle ground between the Sexpot and the Rosa Klebb.
- The Bus Came Back: She appeared as a relatively minor villain in "The Cat and the Claw" (which was actually about Catwoman) and then vanished - only to return a couple of years later as the Big Bad in "The Lion and the Unicorn."
- Canon Foreigner: Never seen outside of the series, probably due to a lack of popularity.
- Color Character: Wears red and is named Red.
- Dark Action Girl: Appears to be capable of some form of martial combat, and had fought Batman once or twice.
- Empty Quiver: "The Lion and the Unicorn" revolves around Red Claw's hijacking of a nuclear missile.
- Gender Misdirection/Samus Is a Girl: Batman thought "Red Claw" was a man until they met.
- Generic Doomsday Villain: No background, little personality, clearly created to provide the conflict Catwoman couldn't.
- Genius Bruiser: A pretty buff lady but an ambitious criminal mastermind.
- McNinja: More like russian kungfu fighter.
- The Plague: Planned to use a government created one to hold Gotham hostage.
- Red Scare: Strongly implied.
- Skunk Stripe: Has a white stripe in her hair.
- Starter Villain: For American viewers anyway.
- Tattooed Crook: Sports a red claw tattoo on her shoulder.
- Terrorists Without a Cause: She seems to be Only in It for the Money.
- The Strategist: A villainous example.
- Western Terrorists: Her and the group she led.
The Ninja / Kyodai Ken
Kyodai Ken, also known as the Ninja, was a skilled ninja and enemy of Bruce Wayne.
- Arrogant Kung-Fu Guy: He's one of the only characters who can pose a real threat to Batman hand-to-hand... and would've killed him if Bats hadn't sort of cheated. He's also a complete lunatic who just likes beating people up.
- Bald of Evil: He has a shaved head and he is not a nice man at all.
- Beard of Evil: A nice goatee to go with his plate.
- Canon Foreigner: Originated and died in the series.
- Dangerous Forbidden Technique: Oonemuri aka “eternal sleep”, a two-fingered death stab he learned from his ex-master's Secret Art.
- Fighting Fingerprint: Kyodai is able to discover Batman's secret identity by having fought both Bruce Wayne and Batman.
- Hand Seals: A frequent user of these.
- Killed Off for Real: Despite Bruce trying to save him, Kyodai is stranded in the middle of lava when Mount Kijiki erupts during their final showdown. All that was left for Kyodai to do was bow to Batman in honor of his Worthy Opponent.
- Ninja: From Japan, even. He tries to make this claim of Batman as well, but Batman identifies more with the honor of the samurai warrior.
- The Paragon Always Rebels: Hinted to have been Yoru Sensei's best student. At least was more experienced than Bruce.
- Revenge: He blames Bruce for getting him expelled from Yoru Sensei’s dojo when they were younger, even though he tried to steal one of Yoru’s swords and was caught.
- Stock Ninja Weaponry: His katana and shuriken.
- Tattooed Crook: Kyodai has a huge tattoo of a Japanese demon's head on his back.
H.A.R.D.A.C. was a supercomputer created by Karl Rossum that has gone rogue.
- Artificial Intelligence: It has this due to being a supercomputer.
- A.I. Is a Crapshoot: Rebelled against his creator to replace humans by robotic copies.
- Canon Foreigner: He was created for the series.
- Cyber Cyclops: Had a single glowing red lens that flashed in time with his speech.
- Gone Horribly Right: In the case of Batman's H.A.R.D.A.C. clone. While it was meant to copy Batman in appearance and persona upon killing the real Batman, it couldn't handle taking a life and kills itself. The real Batman used it to his advantage to survive.
- Evil Knockoff: Was able to create them.
- Fun with Acronyms: "Holographic Analytical Reciprocating DigitAl Computer"
- Kill and Replace: The evil computer HARDAC decided that humans were too dangerous due to their imperfections and began replacing them. While it was planning on killing its victims once it had extracted all the information it could, they are ultimately rescued before it can do so.
- Killed Off for Real: Tried to get Back from the Dead with his Batman duplicate's help and failed.
- Machine Monotone: Well, when you think emotion is bad (for causing suffering)...
- Master Computer: One who masters robots.
- Omnicidal Maniac: Well, a wannabe one.
- They Look Like Us Now: The Reveal of the androids, whereas previously, all robotic minions had been clearly recognizable as such.
- Turned Against Their Masters: Originally, its master plan had its builder Rossum's approval. When he attempted to pull the plug on the mad scheme he had once authorized, but long since rejected, the computer replaced him, too, with an android and carried on with the program.
Mojo / Lloyd Ventrix
Lloyd Ventrix, also known as Mojo, was an ex-con who acquired a suit that allowed him to turn invisible.
- Canon Foreigner: He was created for the series.
- Clothes Make the Maniac: He was already slightly unbalanced, but the invisibility suit became toxic when it was activated and apparently drove him completely over the edge into complete psychopathy.
- Determinator: What more can you say about a guy who's willing to pose as his daughter's imaginary friend while stealing gifts for her, just so he can earn her trust?
- Deadly Upgrade: It's revealed that the plastic he uses for his suit is toxic.
- Disappeared Dad: Due to being a convicted felon.
- Dramatic Drop: When Kimmy tells him they're moving, he drops her doll in shock.
- Imaginary Friend: Poses as one.
- Invisibility: Developed a suit to turn invisible.
- Invisibility Cloak: Stole a supply of a plastic that could bend light around it, and made for himself an invisibility suit (and similarly outfitted his car).
- Invisible Jerkass: And jerkass is putting it mildly.
- Not-So-Imaginary Friend: Masqueraded as imaginary for his daughter.
- Toxic Phlebotinum: Drives him even more off the edge then he was before.
- Tragic Dream: All he did, he did to be with his daughter... but when he reveals himself to her, she rejects him and wants to be with his mother. At the end, she told Batman his mommy will move and his father will never find them again. He could never be with her.
- Villainous Breakdown: When Batman tries to warn him about the suit (and right before he gets defeated), Lloyd replies:"Who cares if it is? With this suit, I can take back my daughter whenever I want! Her mother won't stop me, and neither will you!"
Arkady Duvall was the son of Ra's al Ghul.
- Alas, Poor Villain: His ultimate fate is an old man, destroyed by hardship, and unable to be healed by the Pit as it took his father too long to find him. He is left to die in peace as an old man.
- Ax-Crazy: Gets into duels, hits women, whips subordinates, kills prisonners (well, tries)... You got the idea.
- Bad Boss: He gives The Joker a run for his money.
- Beard of Evil: Well, friendly muttonchops of evil, anyway.
- Break the Haughty: Deserved considering his nasty temper.
- The Caligula: The reason Ra's decided against making him heir to his empire was that he realised Arkady would likely become this.
- Canon Foreigner: He was created for the series.
- Dirty Coward: Once at Jonah Hex's mercy, he begged him miserably for his life after failing to bribe him.
- Fate Worse than Death: 50 years of hard labour? That'll do it.
- Good Scars, Evil Scars: His, dating from his years of fencing at Heidelberg, would actually be a typical good one.
- It's All About Me: Unlike Ra's, who's a Well-Intentioned Extremist, Duvall only seems to care about gaining an empire for himself.
- Laser-Guided Karma:Winds up serving 50 years of hard labour under (we can assume) even worse conditions and harsher treatment than the workmen he lorded over.
- Really 700 Years Old: By the early 90's, anyhow.
- Royal Brat: He's not royalty (at least, not on Daddy's side of the family), but he definately has the 'tude.
- Smug Snake: Has all of Ra's' ego without his qualities. Best exemplified in his duel with Jonah Hex:Duvall: You cannot defeat me. I am a Heidelberg fencing champion.
Jonah Hex: My heart's all aflutter.
Duvall: I'll chop you to pieces!
Jonah Hex: Talk, talk, talk.
Dr. Gregory Belson
An old colleague of Mister Freeze who is kidnapped for his medical expertise when Nora's cryochamber is damaged in the movie Batman & Mr. Freeze: Sub-Zero.
- Canon Foreigner: He was created exclusively for the film.
- Icy Blue Eyes: Contrasting Mr. Freeze's red goggles.
- Even Evil Has Standards: Subverted. He'd never murder an innocent woman...unless you pay him enough.
- Dirty Coward: Abandons everyone to die on the oil rig while he steals an escape boat.
- The Dragon: Not a true example, but close enough.
- Dropped a Bridge on Him: Or a landing deck. Not much time is spent on his death aside from a brief shot of him screaming.
- Fat Bastard: Well, chubby.
- Hate Sink: As Mr. Freeze has more sympathetic motives, Belson is greedy and has no scruples.
- Jerkass: He's hardly a villain but he would surely sell his mother.
- Kidnapped Scientist: Although unlike most examples, he isn't afraid to go along with whatever his captor says.
- Only in It for the Money: Its established that he's rather desperately in debt by the time Victor finds him.
- Pragmatic Villainy: Encourages Victor to stop throwing temper tantrums and shooting at Barbara in case they accidentally damage the organ(s) they need.
A billionaire park owner who kidnaps Mr. Freeze from Arkham in the episode "Deep Freeze" in the hope of becoming immortal like him.
- Affably Evil: He's very warm and welcoming... for a guy who wants to kill the world to create his own utopia.
- And I Must Scream Walker was immortal and trapped under the ocean in a block of ice, although it's eventually reversed by the show's tie-in comics.
- Canon Foreigner: He was created exclusively for the series.
- Corrupt Corporate Executive: Wants a world without anyone he doesn't approve of, where everyone has to obey him.
- Evil Counterpart: As pointed out by a reviewer for the episode Deep Freeze, Walker and Freeze stood in deliberate contrast to each other. Freeze claims to be dead to emotions, but his compassion betrays him several times during the episode: he at first refuses to subject Walker to the same confinement as Freeze himself, and Batman eventually convinces him to help stop the deaths of innocent people. By contrast, Walker is an outwardly warm, paternalistic figure, but he is as dead to emotions as Freeze claims to be, coldly planning mass murder just to create his own fantasy of a perfect world. His transformation into "the second Mr. Freeze" is more appropriate to his inner self than Freeze's ever was. He is a rare example of a evil counterpart to a villain.
- The Evils of Free Will:Walker: My world will have no crime, violence, or pain.
Robin: You can add free will to that list, too!
Walker: A small price to pay for order.
Batman: Your order. For your select few!
Walker: Excuse me, but I fail to see the problem with that.
- Immortality Seeker: Wants to live forever to see his vision for the world carried out.
- Knight Templar: He plans to make a crime-free utopia and freeze Gotham thinking it's too corrupt to survive. Granted, he may have a point there.
- Mr. Alt Disney: Not only a park owner with dreams of utopia, but also ties into the urban legend that Disney was cryonically preserved with his transformation at Freeze's hands.
- No Celebrities Were Harmed: He could be described as "Evil Walt Disney".
- Small Role, Big Impact: He may have massively failed to create a frozen utopia, but Walker did put Mr. Freeze back in business by giving him the motivation to save Nora instead of just seeking revenge. Had he not found her, Victor's criminal career would've been much shorter.
- Utopia Justifies the Means: Seems to believe that freezing everyone on the planet except for his chosen few will help to create a better world.
The CEO of Gothcorp, and the man responsible for the accident that turned Victor Fries into Mister Freeze.
- Asshole Victim: From causing the accident that made Mr. Freeze, to apparently killing Nora, to sweeping all of those things under the table. Can you really blame Mr. Freeze for taking vengeance? Batman does save him, but angrily leaves him frozen.
- Bad Boss: "That 'people company' line is good PR, but when the wage slaves start acting like they own the place, it's time to pull the plug." A phrase here meaning bring large goons along to smash their stuff and possibly kill them.
- Bitch in Sheep's Clothing: Claims Gothcorp is "the people company", and that if Freeze has a problem with them, he'd be willing to talk about it. During his meeting with Bruce, he reveals his true greedy colors and calls "the people company" good PR, but he reveals this to Bruce while still acting friendly and cordial towards him, possibly thinking Bruce is a fellow Corrupt Corporate Executive, oblivious to the fact Bruce is a Honest Corporate Executive who is actually subtly disgusted with Boyle's true colors, to the point he declares "I feel ill" (both figuratively and literally, as Bruce was suffering from a cold following his initial encounter with Mr. Freeze) before politely excusing himself due to his cold.
- Canon Foreigner: Ferris was created exclusively for the series.
- Corrupt Corporate Executive: He refers to his scientists as "wage slaves". And that's the most harmless thing he does in the episode.
- Dirty Coward: Notice he assaults Victor Fries, after he got Fries to willingly lower his gun on him.
- Jerkass: He's a corrupt douchebag who is responsible Mr. Freeze is who he is now, but actually tried to kill both him and his wife for money. To make it worse, He has kept some kind of good guy facade to hide his true nature in years, and has lied about every thing he did.
- Jerk with a Heart of Jerk: He claims to be a part of "the people company". However, as it's discovered, it's all an act so that he could get money, and doesn't care about anyone other than himself.
- Jerkass Has a Point: See Villain Has a Point below.
- Lack of Empathy: To him, money means more than the lives of his employees or their dying spouses.
- Meaningful Name / Punny Name: His name is homophonous with "boil", fitting for the nemesis of a Mr. Fries/Freeze.
- Small Role, Big Impact: He's only in one episode and presumably gets put away for life when his crimes are uncovered. Doesn't change the fact that his actions created Mr. Freeze, who went on to become one of Batman's most prominent enemies, all the way to the distant future. Also, on a meta-example, this role was the very first voice-over role in the DCAU for Mark Hamill, whose performance would lead him to the voice-over role that made him famous, aside from Luke Skywalker, The Joker, which in turn lead him to take up more voice-over jobs up to today.
- Villain Has a Point: His actions clearly become criminal when he assaults Victor despite Fries having already backed down, and his command to pull the plug on Nora is nothing short of heartless, but his complaint is valid. Victor was using equipment that didn't belong to him, and essentially stealing money not just from Boyle, but from the whole company. The project was completely unauthorized, and that's not even going into the legal ethics of using a human subject in a secret experiment.
- Villain with Good Publicity: As the head of the "People Company", he almost receives a Humanitarian Award. When he is exposed, it's gone completely.
Lock-Up / Lyle Bolton
A former security guard at Arkham. Fired for his brutal methods, he decides to take the law in his own hands.
- Canon Immigrant: He was developed for the show and was eventually introduced to the main DCU.
- Create Your Own Villain: He was formerly a guard at Arkham Asylum who got his position due to endorsement and support from Wayne Enterprises. When he goes insane and begins kidnapping the people he blames for the city's problems (the police, bureaucrats and reporters that he says cause the criminals), Robin snarkily comments "Another fine villain brought to you by the Wayne Foundation." The look Batman shoots him is not happy.
- Informed Ability: Apparently, Lock-Up is such a horrific guard that he has driven even the already-insane inmates of Arkham insane, paralyzing the Scarecrow, "The God of Fear," with fear. When his offenses against the patients are actually given, however, it is debatable as to whether they are extreme or standard asylum fare, apart from his mental abuse of the Ventriloquist, possibly because the show could not portray anything worse.
- The Jailer: He likes to lock the objects of his ire into cells.
- Jumping Off the Slippery Slope: Goes from wanting to lock up Gotham's criminals to wanting to lock up Gotham's authority figures for not being extreme enough (such as people like Gordon, who actually captures the criminals to begin with).
- Knight Templar: He may be one of the purest examples of this, being a former head of security at Arkham who was fired for brutalizing the inmates, who comes back as a villain trying to imprison forever the "scum" that he feels represent the people that allowed Gotham to get this way (including the head doctor at Arkham, Commisioner Gordon, Mayor Hill, and Summer Gleeson). In true Knight Templar fashion, he has no idea that he's gone too far (he views Batman as a potential partner, much to the other's disgust).
- Politically Incorrect Villain: A fairly obvious GOP pundit parody. He constantly says that the "liberal media," "coddling doctors," and "gutless police" are responsible for supercrime in Gotham. He believes that the criminals at Arkham don't deserve privileges or even the most basic humane treatment. Obviously, he's hyperbolized, but it's still pretty severe for a kids' show.
- Rabid Cop: Though technically not a cop.
- Sadist: Thinks that criminals deserve to be tortured and clearly enjoys doing it - and when stopped, expands his definition of "criminals" to those who got him fired or condemned his actions, as well as Gordon, the Mayor and Batman because he thinks they are too "soft" on criminals. He is so scary the other Bat-rogues tried to escape Arkham solely to get away from him.
- Steven Ulysses Perhero: A security-themed vigilante named Bolton?
- Straw Character/Strawman Political: He even disparages the "liberal media."
- Villain Has a Point: His methods are extreme and inhumane, but Arkham is a Cardboard Prison, especially for the more dangerous criminals like Joker.
- He is meant to be seen as a hard-headed conservative nutcase with his rant about the inefficient politicians and the "liberal media" being the cause of the superpowered psychos. While "cause" might be a stretch, he's quite right about them being part of the problem. The police routinely fail to combat the maniacs, leaving a vigilante to do 90% of the work, the people running Arkham keep it a barely-functional revolving door, and the politicians for the most part do nothing at all to improve Arkham or Gotham itself. Hell, we even see the news treating Poison Ivy as a media darling instead of a murderous eco-terrorist! If they all did their jobs more efficiently and professionally, maybe there wouldn't be so many costumed freaks terrorizing the city.
- Well-Intentioned Extremist: He... well locks up who he thinks is the real source of the problems in Gotham, the lax Police Force (Gordon), the pushover Doctors (Dr. Bartholomew), mindless Bureaucrats (Mayor Hill), and the media (Summer Gleeson) that "glorifies" the Bat-villains. Ironically, he is probably right.
- With Us or Against Us: Actually says, "If you're not part of the solution, then you're part of the problem." (Throughout the episode, he also blamed the "liberal media," as well as "gutless police, mindless bureaucrats, and coddling doctors" for society's problems, so he's really more of an outright parody of conservative argumentation.)
Anthony "Tony" Romulus
Anthony "Tony" Romulus was a pentathlete and philanthropist turned monster.
- The Ace: Started out as a successful pentathlete and philanthropist.
- Adaptation Name Change: In the comics, his surname is Lupus.
- Big Ol' Unibrow: Sports a thick, black unibrow. In real mythology, it's a telltale sign of a werewolf.
- Bio-Augmentation: Thanks to Milo's formula.
- Broken Ace: The fame and money made him intolerant of any losses at all. His desperation led to him hiring Dr. Milo to make the drug that turned in into a werewolf.
- Evil Is Not a Toy: The only call which could have been less smart than hiring a shady scientist to make you stronger would have been to throw him out once he wasn't needed anymore. Surprisingly, said scientist isn't exactly in a forgiving mood when he actually turns out to be needed once more.
- Heroic Build: He is an Olympian athlete.
- Meaningful Name: Romulus is the name of one of the brothers of Roman lore that was raised by a wolf.
- Our Werewolves Are Different: He turns into a Wolf Man due to genetic splicing rather than a magical curse.
- Superpowered Evil Side: The werewolf, as can be expected.
- Suspiciously Similar Substitute: For Anthony Lupus in the Batman comics.
- Tragic Monster: Has no control over his animal form and clearly resents it.
- The Unfettered: Did whatever it took to win and it cost him everything.
Vertigo was a rogue who tangled with Batman and Talia. He was the leader of a splinter group of the Society of Shadows.
- Bastard Understudy: For Ra's al Ghul.
- Composite Character: A composite of Ebenezer Darrk and the Green Arrow foe Count Vertigo. His name, powers, and Eastern European heritage come from Count Vertigo, while his status as a pupil of Ra's al Ghul and a turncoat member of the League of Assassins comes from Darrk.
- Disc-One Final Boss: He is introduced simultaneously with the Society of Shadows, and played up as their leader, or at least a major big shot. Actually, he is a renegade and leader of a minor splinter faction of the group, and Batman, by defeating him, unwittingly helps the real leader of the Shadows (namely, Ra's al Ghul) to reconsolidate his hold on the organization.
- Disney Villain Death: Falls from a clock tower into a river.
- Eyepatch of Power: That power is to disorientate his victims, making them lose their balance.
- Long-Range Fighter: Never lets Batman or Talia get but so close to him in battle.
- This Is a Drill: Stole a rifle-sized drill from Wayne Enterprises that uses sonic vibration to dig. Uses it against Batman and Talia al Ghul.
Maximillian "Maxie" Zeus
Maximillian "Maxie" Zeus was a former shipping CEO turned supervillain.
- Ancient Grome: Maxie sometimes slips into ancient Roman references, but then again, he’s crazy.
- Astonishingly Appropriate Appearance: Maximillian Zeus had something of an Ancient Grome fetish long before he went crazy, if the architecture of his skyscraper is any indication, plus he had a Heroic Build prior to losing his mind (fitting in with the classical Greek physique).
- Corrupt Corporate Executive: Before he went nuts, he did business with the mob.
- A God Am I: Thought he was the Greek God Zeus after having a nervous breakdown from the stress of doing business with the mob.
- Hope Spot: At the climax of the episode. For a brief moment, it looks as if Maxie is finally coming to his senses... only for the Zeus personality to take over and order Clio to be tied to the electron cannon.
- Large and in Charge: Maxie is huge, taller than Bruce/Batman and massively muscled. He uses it mainly as an intimidation factor and as a means to fit into his "Greek God" aesthetic, as his build does him little good against Batman.
- Made of Iron: Zeus is electrocuted, falls down a story onto concrete, landing on his head, and survives.
- The Muse: Called “Clio” Droukas, his girlfriend and assistant, though she just sees the title as another sad sign of Maxie’s declining sanity.
- Napoleon Delusion: Under the impression he was the Greek god
- Psycho Electro: With his metal thunderbolt and the Lightning Gun he stole from the government.
- Split Personality: One personality is Maxie, the other is Zeus.
- Tragic Villain: Maxie turned to The Mob to bolster his shipping business after an economic downturn and eventually cracked under the stress, forging a personality based on the Greek God Zeus to deal with running his company. His former girlfriend turned 'muse' Clio and his hired goons know that Maxie's lost it, but all are at a loss of what to do about it. Worse, he likely subconsciously stole the Electrical Discharge Cannon as a means to protect himself from probable threats (the Police and the Mob).
Now, at last, mighty Zeus is home...
- How about the ending of that episode? When he is wheeled into his cell at Arkham, he rejoices pathetically—Because in his hallucination, he is finally back home among the gods in Olympus.
Calendar Girl / Page Monroe
A former supermodel who began to lose work as she aged. Obsessed with maintaining her youthful appearance, she underwent cosmetic surgery after cosmetic surgery, and developed a psychosis where she perceived herself as ugly, leading her to don a white mask to hide her features. She hatches a scheme to kill various figures in the fashion industry as revenge, but meets resistance from Batman and Batgirl.
- Bait-and-Switch: Batman is told a rumor that in an attempt to retain a youthful look, Monroe underwent a surgery that was ultimately botched and disfigured her. There's a lot of dramatic buildup in her avoidance of unmasking, until it turns out this was just a rumor- she's still quite lovely.
- Beautiful All Along: After her Cool Mask is removed, but she can't see how beautiful she is anymore.
- Canon Foreigner: A Gender Flip of Calendar Man from the comics, but with a different and a less obsessive motive.

- The Fashionista: Has a costumes for all four seasons.
- Gender Flip: Is based on Calendar Man.
- I Am Not Pretty: Ageism in Hollywood killed her career, and she keeps her "old, ugly" face hidden from the world because of it. She's not that old and has maintained her youthful appearance.
- Ink-Suit Actor: Sela Ward is the spiting image of Page, and has a similar backstory of being turned down for roles for being "too old".
- Sinister Scythe: Wields one of these. Along with her black clothes and hair and white mask, it evokes imagery of The Grim Reaper.
- White-Dwarf Starlet: She's intent on killing the people who had led to her downfall, wearing full-body covering and a featureless mask to hide what she's become since her fame ran out. The Reveal shows that she looks to be in her 30s and is still beautiful, but she "can only see the flaws".
- White Mask of Doom: To cover up her supposedly hideous face.
- Woobie, Destroyer of Worlds: She was a former model for calendars, but constantly failed attempts at rectifying her "hideous appearance" left her with nothing else than a desire of vengeance against the people she perceived took away her beauty. She is later revealed to actually be gorgeous, although she still firmly believes her appearance is repulsive despite this.
The Mad Bomber / Ted Dymer
The villain of the episode "Beware the Grey Ghost", a bomber extorting money from the city in a style modeled after an episode of the in-universe show, The Grey Ghost.
- Beneath Suspicion: When Simon Trent had his Eureka Moment, he cannot believe it:Simon Trent: But I'm not the Mad Bomber, Batman. I'm not. I sold my Gray Ghost cars months ago to pay for my... No, it can't be him.
- Canon Foreigner: He was created for the series.
- Crack Is Cheaper: In-universe. He turned to crime to fund his toy obsession.

- Death Trap: His standard method of "interrogating" someone.
- Only in It for the Money: This seems to be his only real motive besides sadistically interrogating his victims.
- Out-Gambitted: Batman pulls the rug out on him by disguising himself as his client, Wacklaw Joserk, who Wormwood was trying to steal Batman's cowl for in the first place.
- Smug Snake: Boasts a great deal about the flawlessness of his traps and getting one over Batman...only to find out the detective was one step ahead of him the entire time.
- Villain of the Week: Only appeared in one episode and was never heard from again.
Sidney "Sid the Squid" Debris
A small time bumbling crook that seems to have done the impossible: to kill the Batman.
- Anti-Villain: He is a criminal, but he's not evil by any sense of the word.
- Apologises a Lot: "Sorry" is practically his catch phrase: He apologizes when he ruins Thorne's couch, when he trips over Batman, when he explains what happened at the roof, but the most extreme example may be when Joker placed him in a Death Trap for ruining Joker's right to kill Batman."Will it help if I say I'm sorry? I’m really really really really really really sorry!"
- Badass on Paper: He provided the former page image. The guy that killed Batman must be impressive, right?
- Big Bad Wannabe: Wants very badly to be "a bigshot" in the criminal underworld.
- Bumbling Sidekick: Eddie G. set him up as bait for Batman. Sid managed to ruin that plan.
- Canon Foreigner: Mostly so, as he was created for the series, but shares the same moniker ("The Squid") of a comics' Rogue.
- Deconstruction: Sidney deconstructs the Mooks, showing what kind of person would assume the daily risk of working for the Joker or Thorne, or confronting Batman as part of his job.
- Earn Your Happy Ending: He's in prison, but what he's gone through has earned him the respect of his fellow criminals and fulfilled his dreams.Sid: A big shot at last.
- Evil Minion: Subverted, Sid is useless at battle, so he could be this trope, but he is also useless in anything else he tries. He is just not useful enough to be a minion.
- Extreme Doormat: He lacks drive, ambition or even opinions. Things happen to him and he barely reacts. The only time he protests his fate is when Joker puts him in a Death Trap.
- Friendless Background: Nobody likes him. The Mooks thinks he’s useless, Eddie G. set him up as bait, his mother doesn’t talk to him anymore.
- From Nobody to Nightmare: His true dream is to be a Big Shot at Gotham’s underworld. This is the kind of perverted dream all those Mooks share to justify their volunteering to the Mook Horror Show. The worst part is that Sid gets his wish in the only place he could be a winner: At Stonegate prison, surrounded by Straw Losers. Achieving his dream destroys Sid's life."Like a hungry predator, Sid the squids stretches his tentacles throught the Gotham’s underworld. Yeah, good! I’m on my way, Nothing gonna stop me now."
- Harmless Villain: With his small stature, scaredy-cat nature, and lack of any mean bones in his body, he truly has chosen the wrong profession.
- Horrible Judge of Character: He sincerely thinks Eddie G. is a true friend, and he asks for help from Rupert Thorne.
- I Just Want to Be Special: Sid’s only motivation, he wants to be special… somehow… that doesn’t involve him doing anything.
- Invincible Incompetent: Sid seems to be The Fool, but at the end of the story, we discover that he was not being completely lucky, and given he ends in jail, Sid certainly doesn't have Karmic Protection.
- Know When to Fold 'Em: Doesn't put up any resistance upon learning that he's under arrest at the end of his episode, and is rather understanding about it.
- Manchild: When the Mooks gave him a chance to be the look out of a drug shipment, Sid behaves as a Surveillance Station Slacker more interested in making Impossible Shadow Puppets.
- Minion with an F in Evil: The fact that he apologizes profusely for everything should tip you off.
- Mythology Gag: A pre-Crisis Rogue called the Squid briefly existed, but was pretty much an expy of the Penguin and so very different from Sidney. The comics' Squid remains obscure and insignificant today, but the story featuring him included the debuts of 2 much more significant DC characters: Jason Todd and Killer Croc.
- No Social Skills: Justified, Sid is a Manchild Straw Loser with a Friendless Background that makes him a Horrible Judge of Character. His only way to interact with others is putting up with the abuse.
- The Perils of Being the Best: The Gotham underworld assumes Sid is the toughest man in Gotham when they think he killed Batman. Soon everyone in the underworld from genuine tough guys to psychos to wannabes are gunning for Sid, because they want to get the Villain Cred from killing the guy who killed the Bat.
- Phrase-Catcher: After the explosion at the costumes house, everyone salutes him as “The man who killed Batman”.
- Red Baron: “The man who killed Batman”.
- Seemingly Profound Fool: He has no personality of his own, so every competent person sees him as they want Sid to be: Thorne’s Mooks see him as an evil Idiot Hero even when he claims it was an Accidental Murder. The gang-bangers defy him to fight even when it’s obvious he is hopeless. Joker is so upset by being stolen the chance to kill Batman that he claims Sid had Beginner's Luck, and Thorne, who has informants who rightly told him Sid is a Bumbling Sidekick, suspects Sid of trying to pull a Scheherezade Gambit on him using Obfuscating Stupidity.
- Shadow Archetype: Sid has no personality of his own, so every incompetent person (the mooks) sees him as they want Sid to be: One mook who achieved the From Nobody to Nightmare dream. Even when he is in prison and everyone can see him as the loser he is, all they will prefer to see him as the guy who almost killed the Terror Hero, made a fool of the Bad Boss, and set up The Don, all the guys that make a Mook's life a Mook Horror Show.
- Straw Loser: Sid has no talent for anything evil (or anything good either), not any proactivity, he is not good nor evil… to work for Thorne or the Joker is really the only thing left to him.
- Surveillance Station Slacker: When the Mooks gave him a chance to be the look out of a drug shipment, Sid is much more interested in making Impossible Shadow Puppets.
- Villain Cred: At the end of his episode, the other criminals credit him for almost killing Batman, making a fool of the Joker, and setting Thorne up. This is treated as Sid's happy ending.
- Villain Protagonist: The Man Who Killed Batman is told from his perspective.
Salvatore "Sal" Valestra was once the most powerful gangster in Gotham City.
- Awesome Mc Coolname: Possibly the ultimate mob boss name.
- Canon Foreigner: Possibly based on Lew Moxon, who also played a role in Batman's mythos.
- The Don: Was once. Now he is an aged shell of his former self.
- Evil Old Folks: Well too old to try any evil now.
- Greater-Scope Villain: Of Batman: Mask of the Phantasm. Ordering the death of Andrea's father led Andrea to becoming the Phantasm. He could also qualify for the series as a whole since his actions forced Andrea to leave Bruce, the lack of companionship allowed him to become Batman. And the hit man he hired to kill Andrea's father would become The Joker.
- Incurable Cough of Death: Is suffering from one in his old age (implied to be the result of heavy smoking in his youth). The Joker kills him first though.
- Karmic Death: Murdered by the very psycho he sent to kill Andrea's father.
The Sewer King ran a child-slavery racket in the sewers of Gotham City.
- Adaptation Dye-Job: The Sewer King's hair was black in his original appearance, but red during his appearance in the comics.
- Canon Immigrant: He made an appearance during 52, where he is killed by Bruno Mannheim for refusing to join Intergang.
- The Fagin: He had legions of orphaned children forced to steal for him.
- Would Hurt a Child: Would feed them to alligators, that is.
Arnold Stromwell was a prominent mob boss in Gotham City before turning himself in to the authorities. His estranged nephew Tony Zucco was responsible for the murder of the parents of Dick Grayson.
- Being Evil Sucks: Being a crime boss also made him a lonely man with no real friends and cost him his marriage. He later finds out how much he indirectly hurt those he loves when he discovers that his son took the drugs his organization was selling and ended in a hospital.
- Canon Foreigner: He was created for the series.
- A Day in the Limelight: It's Not Too Late is almost exclusively about him.
- The Don: Rupert Thorne's rival at the start of the series. It's implied that he ran Gotham's underground for a long time, before Thorne arrived to challenge his power. He's also a Deconstruction, as his episode shows how much his actions have, albeit indirectly, hurt his family and by extension himself. He's currently divorced and later discovers that his son has been hospitalized because he took the drugs that his organization was selling.
- Even Evil Has Loved Ones: His son and his brother. They double as his Morality Pets. Seeing the effects of the drugs his organization produced on his son and talking to his brother convince him to surrender himself to the police and close down his organization.
- Even Evil Has Standards: He threw Zucco out of the family due to Zucco's giving him unwanted attention from Batman with his murder of the Flying Graysons.
- Heel–Face Turn: At the end of his episode, he agrees to surrender to the police and tell Gordon all he knows about Gotham's criminal world.
- Ineffectual Sympathetic Villain: He's a mobster, but you still feel sorry for him as his personal and professional lives are an utter mess.
- Minor Major Character: In spite of his importance in the settings of the seriesnote , he only appears during one episode (not counting flashbacks) and has a Heel–Face Turn at the end.
- My Greatest Failure: He considers himself responsible for the accident during which his brother lost his leg, as the latter was injured while saving him from a train.
- Papa Wolf: When he thought that Thorne was responsible for the disappearance of his son, he was ready to beat him to a pulp to make him reveal where his son was. Too bad that Thorne wasn't the culprit.
- Sibling Yin-Yang: He is a crime boss, his brother is a honest priest.
- Tragic Villain: As a poor young boy, he was determined that he should one day be someone, and that the criminals and scum should fear him. Through his underworld career, he got his wish—And also an utterly miserable life to go with it.
- Villain Protagonist: The episode It's Not Too Late is almost entirely about him, with Batman playing a supporting role.
- White Gang-Bangers: An Anglo-Saxon mafioso would be a rare thing, even in an age when most "ethnic" criminals were white (e.g., Italian-Americans).
The Condiment King / Buddy Standler
A oneshot villain who only appeared early in "Make 'Em Laugh". At a glance, he just looks like a small time crook with an incredibly silly theme and costume, but it turns out he was a comedian who (along with two others) was brainwashed by the Joker as payback for kicking him out of a stand-up act (one he wasn't invited to, at that).
Despite only having a few minutes of screentime and solely serving as a joke villain, he gained an unexpected degree of popularity due to the inherently silly nature of him, and was eventually added as a recurring extra in the mainstream DC comics.
- Abnormal Ammo: He uses high-pressure guns to squirt out ketchup and mustard, capable of knocking a full grown man at least fifteen feet through the air.
- Adaptational Badass: Downplayed. He occasionally popped up in the mainstream DC universe, and in spite of his insipid gimmick, he shows potential to be a legitimate threat, if only because his condiment guns have spices that rank 100,000 on the Scoville meter and can cause anaphylactic shock to those sprayed by him, as Robin and Black Canary find out. He eventually got his weapons upgraded to shoot corrosive acid when he joined General Immortus' army. In spite of this, he's still treated as a joke by superheroes and law enforcement and always ends up getting his ass handed to him.
- Adaptational Wimp: However, his initial comic appearance in Batgirl: Year One made him even more pathetic than his cartoon counterpart. He's just a disturbed young man "armed" with off the shelf ketchup and mustard bottles. He doesn't even manage to harm anybody before Robin hands him his ass on a silver platter.
- Adaptational Name Change: His comic counterpart is renamed Mitchell Mayo.
- Alliterative Name: His DCU comic counterpart has the name Mitchell Mayo.
- Adaptational Villainy: In the cartoon, he was just a comedian brainwashed into being a bad guy. The comics make him a crook of his own volition.
- Blazing Inferno Hellfire Sauce: The Condiment King's most effective attack was squirting a restaurant patron in the mouth with a packet of hot sauce. In the comics, he notes to Robin that his spices reach 100,000 on the Scoville Scale.
- Bottomless Magazines: He seems to have an infinite supply of sauces in his barrels.
- Brainwashed and Crazy: In his initial appearance, he was just a comedian brainwashed into being a crook by Joker. His comic appearances just make him a standard crook.
- Bring It: As soon as he meets him, King foolishly challenges Batman to a fight. Batman promptly wipes the floor with him.
- Bullying a Dragon: He honestly believed himself to be a legitimate threat to Batman and goads him into a fight—in mere seconds, Batman effortlessly takes him down.
- Butt-Monkey: He manages to become this in just his few minutes in the limelight. He's all but laughed out of the restaurant he's trying to hold up (until he shows he can be something of a threat to them), gets effortlessly beaten by Batman in a fight, and ends up falling off a building onto a police car by slipping on his own ketchup.
- The Cameo:
- Canon Foreigner: He was a new character created just for the episode "Make Em Laugh".
- Canon Immigrant: Originally a oneshot joke villain for this series, he made his way into the mainstream DC universe, where he's still a goofy looking villain, but it is made into something resembling a legitimate, if minor, threat.
- Cheap Costume:
- Just look at him. He wears a jumpsuit that looks like it was dug out of a Goodwill dumpster, dons a pickle headpiece and literally wears underwear as part of his costume.
- His initial costume in the comics isn't even a costume at all—he just wears a normal shirt and pants with a checkerboard tablecloth as a cape, with orange gloves, a backwards baseball cap and a domino mask. In other words, he looks like the kind of teenage loser you'd meet working at a local fast food joint.
- His third costume in the comics is slightly less ridiculous than the previous two (he ditched the underwear and baggy clothing for a black and red jumpsuit), but it has salt and pepper shakers as headpieces, and by his third appearance its clearly falling apart and looks like it was just sewn back together, with clearly visible patchwork and holes in it.
- Chest Insignia: Has a lone C with a lightning bolt on his chest. His comic appearances change it to a cartoonish crown.
- C-List Fodder: He's at the bottom of the villain food chain as far as being a threat to Batman. In Final Crisis Aftermath: Run, he is seemingly killed after being betrayed and bludgeoned by the Human Flame with his own ketchup and mustard guns. He was eventually revived in DC Rebirth.
- Curb-Stomp Battle:
- All it takes for Batman to beat him is a single punch to the stomach.
- In his appearance in Batgirl: Year One, Robin defeats him with a simple flip and kick.
- In his second comic appearance, he manages to send Robin and Black Canary into anaphylactic shock, Blue Beetle quickly defeats him by spraying him with milk, which knocks him down and douses his spices.
- In his third comic appearance, Batman just knocks him down with a punch to the face.
- In his cameo in The Lego Batman Movie, Batman quickly defeats him with a Groin Attack.
- Disney Villain Death: Averted; he somehow manages to survive a fall from a few stories onto a police car, but he is seriously injured as a result.
- Easily Forgiven: Due to being brainwashed while acting as the Condiment King, Buddy is immediately and rightfully acquitted of charges for holding up the restaurant once the Joker's scheme is uncovered.
- Edible Ammunition: Employs guns that squirt out ketchup and mustard, and also carries packets of hot sauce with him.
- Harmless Villain: He's absolutely no match for Batman in combat. Batman reacts with annoyance upon hearing about him on the Batmobile's radio, and finds him to be such a pathetic foe that he actually offers to go easy on him if he drops the act right then and there.
- Not-So-Harmless Villain: However, he at least successfully held up and robbed a restaurant despite only having condiments as his weaponry. In the comics, he manages to get the advantage over Robin and Black Canary by giving them anaphylactic shock with his spices—only for Blue Beetle to defeat him by spraying him with milk.
- Hoist by His Own Petard: After Batman mops the floor with him, he tries to squirt Bats with ketchup and tries to make a getaway after some boasting, but he slips on some of it that fell on the floor and nearly falls to his death, only cushioned (and seriously injured) by falling onto a police car.
- Hollywood Acid: In the comics, he eventually gets his guns upgraded to shoot corrosive acid instead of kitchen condiments.
- Large Ham: His introductory scene has him introduce himself to a fancy dinner banquet with all the bravado of an A-list supervillain.
- Lean and Mean: His comic counterpart is considerably more thin than the stockier look he had in the cartoon.
- Locking MacGyver in the Store Cupboard: Lampshaded by the King himself in his second comic appearance. He notes that while he was locked up in Arkham Asylum, they gave him a kitchen job for therapy, which gave him time to refine his recipes. He also had the help of Poison Ivy to learn about all the varieties of spices and condiments out there to add to his arsenal."Those costumed clowns locked me away all those years ago. After a while those morons gave me a job in the kitchen for therapy. They let me work on my recipes. Idiots!"
- Improbable Weapon User: You try to find another villain who unironically uses kitchen condiments as weapons.
- Internal Homage: He's a parody of the cartoonishly campy villains of the 1960's Batman TV series.
- Made of Iron: Downplayed, but anyone who could even remotely survive falling onto a police car from several stories has to count as this, even if he was severely injured from it.
- Malicious Misnaming: Batman uses this on him, but its more disdainful than outright malicious, and apparently intended to bring the Condiment King to his senses by pointing out how utterly ridiculous and non-threatening he looks:
- Pungeon Master: He makes no less than six condiment-related puns in his few minutes of screentime. Makes sense considering he's a brainwashed comedian.Condiment King: What's this? Ah, the Big Bad Bat Guy. I knew you'd ketchup to me sooner or later. How I've relished this meeting. You, the Dynamic Dark Knight, versus me, the Conceptual Condiment King! Come Batman, let's see if you can cut the mustard.
Batman: (Batman delivers a single punch to CK's stomach) Quiet!
- Punny Name: His DCU comics counterpart is fittingly named Mitchell Mayo.
- Red and Black and Evil All Over: In the comics, his costume dons this scheme, but it hardly makes him look any more intimidating.
- Sinister Shades: Wears a pair of tinted glasses as part of his costume. It really doesn't make him look anymore imposing.
- Shout-Out: A fast food themed character with King in his name? Now where could that have come from...
- Slasher Smile: In his second comic appearance, he donned a pale Joker-like complexion and has a mean set of teeth to go with it.
- Small Name, Big Ego: He has a huge ego and is a boisterous, smug braggart. When Batman confronts him, he has the audacity to consider himself his equal and dares him to even fight him.
- Smug Snake: His confidence is proportionate to how ridiculous he looks. He has the nerve to even talk Batman down right to his face.
- Thin Chin of Sin: By sheer coincidence, Buddy Standler had this before he was brainwashed into becoming the Condiment King—it just so happened to match the crooks nature.
- Underwear of Power: He actually wears a pair of tighty-whiteys over his costume.
- Villain: Exit, Stage Left!: After Batman beats him, he tries to flee after some boasting, but slips on some of his own ketchup and is sent falling off a railing several stories down. Miraculously, he survives, but is seriously injured.
- Villain of the Week: A D-List villain who made one brief appearance in the series, but he eventually made appearances and cameos in other parts of the Batman franchise.
- White Gloves: Wears a pair of these as part of his costume. The comics change it to orange and then red gloves.
A low-level mobster under his uncle, Arnold Stromwell. In an attempt to start a protection racket over Haley's Circus, Zucco sabotages the "Flying Graysons" trapeze act, killing Dick Grayson's parents.
- Adaptational Attractiveness: In Robin's origin story from the comics, Zucco is an older, obese crimelord. In BTAS, he's in his late 20's or early 30's, has an average build, and seems to be somewhat handsome.
- Bad Boss: Nearly shoots his own mooks with a Tommy gun because the spray of bullets would kill Batman, too.
- Big Bad Wannabe: Clearly has aspirations to get rich and powerful off of his extortion scheme, but is too brash and arrogant.
- Dirty Coward: Skips town at any sign of trouble and fights dirty when he has to get violent.
- Jerk Ass: He's a loud, rude, and totally remorseless scumbag. He shows no regret in killing the Graysons and orphaning Dick, and when he runs into the poor kid later, he berates him for how inconvenienced he is at Dick being a material witness to the crime.
- Make It Look Like an Accident: Zucco frays the ropes used for the Graysons' trapeze act to create an "accident" in retaliation for circus owner Mr. Haley refusing to pay him protection money.
- Shame If Something Happened: His M.O. is sabotage for extortion purposes.
- Small Role, Big Impact: He's a small-time extortionist only appearing in one two-part episode, but his criminal activities resulted in Dick Grayson becoming Robin.
- Trigger Happy: Goes nuts with a Tommy gun throughout the final act of his episode. First he blows a hole in the roof of his hideout to force Batman out of hiding, then turns a nearby amusement park to Swiss cheese trying to fight the Caped Crusader.
- Would Hurt a Child: In addition to the unlikelihood that he was ignorant to ten-year-old Dick Grayson being in the trapeze act he sabotaged, Zucco later flat out attempts to kill Dick so the boy won't testify against him.
- Younger Than They Look: While Zucco was a healthy looking man in his mid to late twenties when he killed Robin's parents, by the time he meets up with the dynamic duo in the present, he looks much much older even though only 8-10 years have passed. His face is gaunt and he has heavy bags under his eyes that suggests he doesn't sleep well. This is almost certainly because he's been fearing that Batman will find him while on the run from Gotham.
