The Team (Season One, Season Two, Season Three) | Nightwing's Team | Batman Incorporated | Outsiders | Justice League | Other Heroes | The Light | Minions of the Light (League of Shadows) | The Reach | Other Villains | Other Characters
This page is for listing tropes related to villains who operate on the behest of the organization known as The Light in the animated series Young Justice.
Immediate SubordinatesVillains who work directly for one or more members of the Light.
Children of Vandal Savage
Voiced by: Zehra Fazal
Vandal Savage's daughter and a member of the League of Shadows.
- Ambiguously Brown: Cassandra has a noticeably darker skin tone than her father, but lighter than her sister. She's clearly mixed-race, as her father is a Neanderthal, but her mother's ethnicity is unclear.
- Anti-Villain: Cassandra genuinely believes in her father as a hero and savior, and regards fighting beside him as defending the Earth, not unlike any of the Team feel when they fight alongside their Justice League mentors. She's also fond of her sister Olympia, expresses shock when Savage euthanises her, and mentions a friendship with Tara Markov that was formed while the two trained with the League of Shadows, expressing disappointment at Tara's absence from Santa Prisca.
- Canon Immigrant: Cassandra Savage first appeared in Legends of Tomorrow, and was herself a Composite Character of Kassidy Savage and Scandal Savage.
- Even Evil Has Standards: Although she quickly justifies it as merciful, Cassandra is clearly shocked at seeing her father kill Olympia.
- The Stoic: Unlike her more eccentric older sister, Cassandra is much more serious.
- Villainous Friendship: In "Exceptional Human Beings", Cassandra mentions taking a liking to Tara Markov during their training with the other Shadows.
Voiced by: Jenifer Lewis
The elderly daughter of Vandal Savage.
- Anti-Villain: Only a "villain" in the sense that she's entirely loyal to Vandal Savage, and even then, Olympia never commits any villainous deeds in her screentime, and her loyalty to Savage is based almost entirely in her adoration of her beloved father.
- Canon Foreigner: Olympia does not exist in DC Comics, nor did she exist in the first pass of episode 7's script. Vietti conceived of her and added her in rewrites.
- Daddy's Girl: She has an almost childlike enthusiasm for her father's story, openly regards him as a savior, and is clearly much beloved by Vandal in turn. Vandal ends her life out of fear her senility will derail his plans, cradling his daughter as she dies and insisting that she be given a funeral worthy of the gods.
- Deadpan Snarker: Olympia quips about Kalibak's "daddy issues" after her father riles the brute about lacking Darkseid's favor.
- Mercy Kill: Savage asks her to tell him about her favorite story and quickly kills her before she realizes what's happening. Cassandra quickly rationalizes it as this trope.
- Neck Snap: Vandal ends his daughter's life by quickly snapping her neck to ensure that she dies with minimal pain or realisation of what's happening.
- Scatterbrained Senior: She has grown senile from old age. She asks Cassandra three times if she's read the same story, notices the second attacking fleet but just stares calmly at the screen instead of immediately bringing it to Vandal's attention, and Vandal's dialogue implies that he's told her multiple times not to record his life story.
- She Knows Too Much: Part of the reason Savage kills Olympia is because her senility makes her a liability. She keeps recording his life story despite repeatedly being told not to, and his plans have yet to come to fruition.
Species: Cybernetically-enhanced human
Lex Luthor's assistant and bodyguard.
- Adaptational Badass: Mercy isn't normally depicted as a cyborg with a laser arm cannon. She's also competent enough to fight Arsenal and give him some serious trouble.
- Ambiguously Human: There's discussion as to just how much of her is human. She seems to be Made of Iron, taking far more damage than the average human, she barely speaks and follows Lex blindly and with little to no emotion, and Lex's intense trust in her is a bit surprising. On the other hand, she does bleed, but only after being thrown into a car so hard the car is totaled.
- An Arm and a Leg: Gets her cybernetic right arm blown off courtesy of Arsenal.
- Arm Cannon: Her right arm can turn into a laser cannon.
- Artificial Limbs: Her right arm.
- Battle Butler: She's Lex's right hand woman and his bodyguard as need be.
- Bodyguard Babes: To Luthor.
- Combat Stilettos: Mind you, she didn't get dressed intended for combat, but she never wears anything other than high heels.
- Cyborg: Greg Weisman confirmed on Ask Greg that Mercy is one and has at least one cybernetic limb.
- Dark Action Girl: She kicks some serious ass.
- Dangerously Short Skirt: Her outfit shows a lot of leg.
- The Dragon: To Lex Luthor. As befitting the trope, she fights so he doesn't have to.
- Emotionless Girl: Doesn't display any emotion over the course of the series.
- Undying Loyalty: Mercy seems to be a very loyal, caring and protective bodyguard to Luthor. She performs multiple tasks that range from driving Luthor around to dressing him up and safeguarding his life.
- The Voiceless: This is the only incarnation of Mercy Graves who never says a single word.
Voiced by: Dee Bradley Baker
Monsieur Mallah is an intellectually enhanced gorilla who works under the Brain.
- Alliterative Name: Monsieur Mallah.
- The Dragon: To the Brain.
- Gatling Good: Uses a minigun in battle.
- Genius Bruiser: Doesn't say much, but he was prepped to assist in brain surgery.
- Killer Gorilla: A given, as he's the Brain's bodyguard and enforcer.
- Mighty Glacier: Big and strong, but rather slow physically, as would be expected for a gorilla.
- Nice Hat: Likes to wear a red beret.
- The Quisling: He betrayed his fellow gorillas to work for their captor, the Brain.
Project CadmusAn underground (literally) genetic engineering lab formerly run by Dr. Mark Desmond and later by the hero, the Guardian. The lab is responsible for creating Superboy from Superman's stolen DNA. The Board of Directors are actually the leaders of The Light.
Blockbuster (Dr. Mark Desmond)
Mark Desmond voiced by: René Auberjonois
Blockbuster voiced by: Dee Bradley Baker (Series), Greg Weisman (Legacy)
The former head of Washington's Cadmus Labs before becoming Blockbuster.
- Blood Knight: Joins Kylstar and other bruisers to re-take his home planet to get "glorious battle".
- Body Horror: His transformation involves his skin ripping off.
- Mad Scientist: An evil geneticist who specialises in cloning.
- Metamorphosis: It appears his transformation is permanent.
- Mind Control: Uses the G-Gnomes to suppress the wills of his co-workers and their subjects.
- One-Winged Angel: After he drinks the blockbuster formula, he transforms from a middle-aged scientist to a large, grotesque monster.
- Painful Transformation: His transformation into Blockbuster looked very painful.
- Put on a Bus: In season two. Explained in the comic tie-in as having joined Kylstar's posse to liberate his home planet.
- Red Eyes, Take Warning: In his Blockbuster form.
- Smug Snake: Very confident in his control over Superboy and the power of Project Blockbuster. Neither work out well for Desmond.
- The Speechless: After his transformation, he appears to be incapable of human speech.
- Starter Villain: The first villain the Team faces.
- Super Strength: Strong enough to give Superboy a pounding.
- Super Toughness: He's so tough, that he had to have a building fall on him just to knock him out.
- Two First Names: His last name is more common as a first name.
Guardian II (Jim Harper II)
Species: Human clone
Voiced by: Crispin Freeman
Jim Harper is a Cadmus clone, formerly active as the head of security at Cadmus's Washington, D.C. facility as Guardian.
- Anti-Villain: He's not a bad guy at all and just happens to work for the villains, and he barely even knows it.
- Badass Normal: Guardian is proficient in hand-to-hand combat, besting Aqualad in it.
- Big Little Brother: Jim is one of the two clones (the other being Red Arrow) of the original Roy Harper. Between the three, Jim is technically the youngest and looks much older.
- Brainwashed: At the hands of the G-Gnomes, as well as his Cadmus programming.
- Cloning Blues: Revealed to be a clone after the Time Skip in the second season. He's taken it a lot better than Roy, accepting that the Kill and Replace policy of Cadmus means the original Roy Harper is dead. note
- Cool Helmet: During his time as Guardian, he wore a golden helmet.
- HeelFace Turn: The last we see of him in season 1, he's under the control of the Light (and in a way, always was). By season 2, five years later, he has since broken away from the Light and from Cadmus.
- Heroic Build: Zigzagged. He thinks he's part of the good guys, but he has been brainwashed by the Light to do none too heroic things.
- Legacy Character: Succeeds Roy Harper's great-grandfather, whose name was Jim Harper and was the original Guardian.
- Luckily, My Shield Will Protect Me: He carries a golden heater shield on his wrist.
- Real Men Wear Pink: If a remark from Roy in "Private Security" is anything to go by, Jim apparently enjoys gardening. Revealed in the season 3 finale to be a play on words as he lives in Geranium City. Which just so happens to be the new location of the Cadmus Genomorphs after they relocated to be free of Cadmus and Luthor, resolving a lingering plot thread from season 1 in the process.
- Reasonable Authority Figure: Guardian is a calm level headed figure of authority. Unlike his employer, Dr. Desmond, he tends to be a bit more open minded on certain issues and will seek a peaceful resolution if possible.
- Retired Badass: He retired as Guardian between seasons, working as a security guard alongside the original and Clone!Roy aka Will.
- Shield Bash: Uses his small shields for combat.
- Took a Level in Cheerfulness: After being quite serious and business-minded during the first two seasons, in Outsiders, Jim is much more cheerful, chuckling at Will's jokes and smiling while fighting Brick's thugs.
- Uncanny Family Resemblance: As noted by Superboy, he looks a lot like his nephew, Roy Harper. Turns out they're both clones of the same person.
Voiced by: Phil LaMarr
Dubbilex is a genomorph, a G-Goblin created by Project Cadmus.
- Adaptation Personality Change: He was more bumbling and out of his element than sneaky in the original comics and not nearly so enigmatic, though he did have his moments.
- Adaptation Relationship Overhaul: In the comics he was very much a father/responsible older brother figure to Kon-El, one of Kon's most trusted friends and the one who stayed with him the longest out of all of Kon's supporting cast in Superboy. Here they interact briefly and Conner is suspicious of Dubbilex's behavior.
- Composite Character: "Dabney Donovan" is an alias used by Dubbilex while disguising himself from humans as opposed to a separate person who was a Mad Scienist.
- Creepy Monotone: Though he turns out to be not such a bad guy at all.
- Enigmatic Minion: To Cadmus, though he turns out to be secretly working against them.
- La Résistance: Believes in acquiring freedom for all genomorphs, even subtly aiding Superboy's escape to help his own cause.
- Mind over Matter: He has telekinesis.
- Power Glows: His horns glow red when he's using his powers.
- Red Eyes, Take Warning: A subversion since even though he has red eyes, he really isn't one of the bad guys.
- Telepathy: He's a telepath.
- What Happened to the Mouse?: Doesn't appear after Season 1, so it's unknown whether he led his fellow Genomorphs to freedom. But presumably Cadmus isn't affiliated with the Light anymore, if it exists at all, since the Light is relying other Evil Science facilities in later seasons. He finally shows up again in season 3, as mayor of a town he and his fellow Genomorphs founded with the League's help so aliens would have somewhere they could stay on Earth without fear of persecution.
Species: Kryptonian clone
Voiced by: Nolan North
Match (also known as Project Match) is a genomorph, and the first attempt at cloning Superman.
- Berserk Button: Anyone else wearing an "S" on their chest. Recall that Connor used to react badly to that too, but got over it.
- The Berserker: Match is too feral and insane to even speak, let alone use any kind of strategy in battle.
- Black Eyes of Crazy: Looks exactly like Superboy, except his eyes have black sclera.
- Body Horror: Thanks to Clone Degeneration, Match is left as a deformed monstrosity.
- Clone Degeneration: During the five-year skip. His right arm, left leg, and head become disfigured and deformed, and his skin is now pale.
- Cloning Blues: The cloning process left his DNA unstable, rendering him insane. Later decays physically as well.
- Composite Character: Comics Match mixed with S-01, as well as a little Superboy-Prime and certain incarnations of Bizarro.
- More powerful clone of Superboy — Match.
- Cadmus's first attempt to clone Superman which failed due to his instability — S-01 or "Bizarre-O".
- Flawed Kryptonian clone, mirror-image S — Bizarro. In the tie-in comic, he also becomes more deformed and gains the pale skin.
- "Original" Superboy, Black sclera, burning the S onto his chest with heat vision — Superboy-Prime.
- Evil Counterpart:
- To Superboy — Both are clones of Superman and were created by Cadmus (by the Light's order) to ensure a replacement for the Man of Steel. They even are given the same character introduction — being released by a member(s) of the Team and then beating them up as a result. However, Superboy only has a few of Superman's powers and learns how to control his anger; Match has all of Superman's powers, but is feral and lacks control.
- To Superman — Both have the same powers but while Superman is a controlled All-Loving Hero, Match is an insane Berserker.
- Flawed Prototype: To Superboy. While Match has all of Superman's powers, he is also uncontrollably insane.
- Meaningful Name: The point of the cloning project was, in Luthor's words, for Superman to "meet his match".
- Psycho Prototype: Cloning kryptonian DNA makes it unstable; which is why Match is so feral.
- Screaming Warrior: His dialogue is nothing but shouts and grunts.
- The Speechless: He seems unable to form words.
The League of Shadows
A pseudo-religious criminal organization.
Lord Kobra (Jeffrey Burr)
Voiced by: Arnold Vosloo
Kobra is a supervillain who considers himself to be a living god, the Lord Naga-Naga. He is the leader of the pseudo-religious criminal organization, the Cult of the Kobra.
- Arrogant Kung-Fu Guy: Kobra comes off as haughty, confident and very prideful.
- Authority Equals Asskicking: Proves to be very much superior to Robin in combat. He basically just stands still whilst blocking all of his attacks.
- Bald of Evil: No hair, and a criminal cult leader and agent of the Light.
- A God Am I: He considers himself a living god and makes every attempt to act like one.
- In the Hood: Wears a hooded cape that resembles a king cobra's hood.
- One-Winged Angel: In the comic tie-in, he orchestrates a human sacrifice on his twin brother to become a giant snake-man.
- Red Eyes, Take Warning: He has red eyes, seemingly the result of albinism, and is an evil cult leader.
- The Stoic: The most emotion he shows is mild annoyance at the Team's interference.
- Walking Shirtless Scene: Kobra never wears a shirt.
- What Happened to the Mouse?: Despite being set up as one of the main minions of the Light alongside Sportsmaster early on, he only appears in one episode and one comic, and then never appears or is mentioned again, and after the timeskip his minions are working for Queen Bee without explaination.
OnslaughtA group of metahumans that works for Queen Bee.
Voiced by: Alan Tudyk (Series), Jeff Bennett (Legacy)
Psimon is an agent of Queen Bee.
- Arch-Enemy: To Miss Martian.
- Bald of Evil: He has no hair, revealing his transparent skull.
- Butt-Monkey: Things tend to go wrong for him whenever he appears.
- Catch Phrase: "Psimon says."
- Combat Pragmatist: When he faces M'gann again after the timeskip, he immediately takes her on despite his previous loss. When called on this by Icicle Jr., he points out that he can keep her occupied long enough for his cronies to dispatch her now-defenseless body. Doesn't work out, of course, but the strategy was sound.
- The Dragon: To Queen Bee.
- Evil Counterpart: To M'gann. He's got all the same Psychic Powers but none of the ethical restraints she possesses.
- He Knows Too Much: When he gets dangerously close to discovering her and Aqualad's treachery, Tigress puts him in a coma.
- In the Hood: He wears a hoodie and occasionally uses the hood to hide his big brain.
- Laser-Guided Amnesia: If he gets into your mind, he can do this to you!
- Let's Get Dangerous!: He's cheerful and relaxed in "Bereft"; though dangerous nonetheless, he doesn't think of the team as a threat. It's the same in "Image", except in this instance he's using Miss Martian's fears against her, which backfires horribly. In "Beneath", he's no-nonsense and brutal.
- Mind over Matter: Can also do this, but doesn't very often.
- Mind Rape: He and Miss Martian take turns doing this to each other. The first time he does it he manages to get the whole Team in one go.
- My Brain Is Big: His swelled, telepathic brain is visible under his transparent scalp.
- Pet the Dog: As a favor to Manta, he is called in to fix Kaldur after his Mind Rape. Though it is spoiled by Tigress putting him into a coma when he finds out her and Aqualad's true allegiance.
- Relationship Upgrade: Seems to be the case in season 3 as he calls Devastation "My love" while expressing concern about her while she is fighting.
- Surrounded by Idiots: He had a solid plan and good improvisation in "Beneath", unfortunately "Stab Miss Martian while I keep her occupied" was too complicated for Icicle Jr. to handle.
- Telepathy: He's a telepath, more skilled but not as strong as Miss Martian.
- Third-Person Person:"Psimon can't see you, Psimon can't catch you, but Psimon can make you... forget!"
Voiced by: Diane Delano
Devastation is a supervillain, and a known associate of Queen Bee.
- Abhorrent Admirer: Would appear to be Psimon's. At the very least, his reaction to her advances is that of unease.
- Brawn Hilda: She's large, domineering, aggressive, and intimidating, not to mention that Psimon doesn't exactly look like he enjoys the fact that she has the hots for him.
- The Brute: But not stupid (or at least not overtly so). In fact, upon discovering Wonder Girl in "Beneath", she's the first to catch on to the presence of the other members of the Team.
- In a Single Bound: She can jump really high. Useful for catching stray Wonder Girls.
- Minion Shipping: While one-sided, her lines and behavior towards Psimon in "Beneath" indicate some sort of attraction on her part. Doesn't even seem to mind that Psimon's got a good twenty years on her. See also: Brains and Brawn, Tiny Guy, Huge Girl.
- No-Sell: Subverted. Initially able to completely shrug off a stream of electricity from Black Lightning, which had just KO'ed the Terror Twins mere moments ago. ("Ha! Tickles.") At least until Black Lightning turned up the juice enough to make her pass out.
- Relationship Upgrade: Looks like Psimon finally gave her a chance in season 3, with him referring to her as his love and her being even more affectionate with him (when he's knocked out) to the point of planting kisses on him.
- Smug Snake: Very confident, but ultimately fails to back up her boasts and loses to Wonder Girl.
- Smug Super: "Do you really think you stand a chance, Blondie? I've gone toe-to-toe with the actual Wonder Woman!"
- Super Strength: She's as strong as Wonder Woman and Superman.
- Super Toughness: And as tough.
- Tattooed Crook: Sports thorn tattoos across the left side of her face, as well as her left arm.
- Younger Than They Look: Much younger. According to Word of God, she's only 1 by the end of Season 1. note
Mammoth (Baran Flinders)
Voiced by: Dee Bradley Baker
A member of the Cult of Kobra and Shimmer's twin brother.
- Adaptational Badass: Downplayed. In the comics, he was pretty strong and formidable, but in the series, he's the juggernaut. Case and point: he fought Bane in the comics and lost, here it was a Curb-Stomp Battle in his favor.
- Big Brother Instinct: Not very happy when his sister was Mugged for Disguise.
- Body Horror: He makes Bane's transformation look like a minor adjustment. Some parts of his skin rip to expose his muscle tendons!
- The Brute: Consistently acts as unspeaking muscle to more intelligent villains.
- Curb-Stomp Battle: Delivers a pretty vicious one to Bane.
- Half-Identical Twins: He and his sister, Shimmer, before he took the formula.
- Lightning Bruiser: Rapidly and brutally beats the living daylights out of Bane.
- Metamorphosis: His transformation is permanent.
- Mook Carryover: Once a part of Kobra, now part of Onslaught.
- Painful Transformation: His transformation looked quite agonising.
- Super Serum: His transformation was caused by kobra-venom, a mixture of the blockbuster formula and the venom formula. It permanently increases strength three times stronger than regular venom.
- Super Strength: Stronger than Bane.
- Weight Taller: Kobra-Venom transforms Mammoth from a scrawny beanpole into a massive, misshapen hulk: far taller, heavier and more muscular than he had been before.
- Younger Than They Look: Before his transformation, Mammoth looked about 18 or 19 but after it he looks considerably older.
Shimmer (Selinda Flinders)
Voiced by: Danica McKellar
A member of the Cult of Kobra and Mammoth's twin sister.
- Bald Woman: At least half her head seems to be missing hair for some reason, possibly for the tattoo she has there.
- Butt-Monkey: Gets pwned with ease almost every time she appears.
- Faux Action Girl: Big time. She's played up as The Dragon to Lord Kobra and seems to be his most trusted underling, but tends to get her ass kicked every single time she gets into a fight. Even after her metagene is activated in Season 2, she's no more of a threat.
- Half-Identical Twins: To her brother, Mammoth, before his big change.
- How Do I Shot Web?: Her Reach-induced powers manifest for the first time during a battle, melting a hole in the ship's hull that allows the Team to escape.
- Mook Carryover: Once a part of Kobra, now part of Onslaught.
- Reality Warper: Basically her powers when the Reach activate her metagene. She can turn any substance into any other, though seemingly only to break it down into particles.
- Ungrateful Bastard: After pulling her out of her experimental pod and getting her to safety along with the rest of the taken, she turns on them. Though it's possible that she had volunteered for the experiment, and the heroes thought they were rescuing her when she was pulled out.
- Wrench Wench: She was able to repair a sabotaged helicopter, suggesting some mechanical talent.
Icicle Jr. (Cameron Mahkent)
Voiced by: Yuri Lowenthal
Icicle Jr., also known simply as Icicle or Junior, is an enemy of Green Arrow and Speedy.
- Abhorrent Admirer: For Tuppence Terror. His attempts at flirting creep her out (both the real Tuppence and Miss Martian posing as her).
- Adaptational Dumbass: While not a genius scientist like his father, Cam is clever enough in the comics, not the absolute dunce he is in the show.
- Adaptational Jerkass: While his comic counterpart was still a jerk, he also felt Trapped in Villainy due to his appearance and genuine camaraderie with his teammates, and even expressed a wish that he could be a hero. Here, while he definitely has standards, he's a lot less sympathetic. He seems to have mellowed out in Season 3, though, even sincerely congratulating Superboy on his engagement.
- Amazing Technicolor Population: Justified. His skin is light blue (with or without activating his powers) because he was born with cyrokinetic powers.
- Beard of Evil: He's grown a chinstrap between Seasons 2-3, though he seems to actually be somewhat less evil.
- Childhood Friends: With Artemis, as shown in the tie-in comics. He is unaware that she now works as a superhero.
- Dumb Muscle: "Muscle" in this case referring to his powers (physically, Junior's pretty lean). Junior's powerful, but is a complete idiot, being played like a cheap fiddle by Superboy and managing to bungle a simple plan laid out by Psimon.
- Even Evil Has Standards: From when Superboy and Miss Martian kissed while disguised as brother and sister, it becomes apparent that whatever sort of wrong he is, he draws the line at incest.
- Friendly Enemy: When he and Superboy cross paths in Season 3, he recognizes Conner through his mask, and gives him sincere congratulations for his relationship and recent engagement with M'gann; saying he thought they made a great couple, and that it gives him hope for himself, and Superboy in turn hopes he does find someone. While in the middle of fighting each other.
- An Ice Person: Icicle has the ability to create large ice crystals from his own body, and freeze the air around him to create various obstacles. He has demonstrated the ability to sling crystals great distances, which freeze whatever they strike on contact. He can also shoot light blue beams of ice.
- Icy Blue Eyes: He has blue eyes, and while he be a comic relief, he's still a villain.
- Jerkass: He is very psychotic and cares very little about other people's well-being.
- Jerk with a Heart of Gold: He seems to have gotten nicer in Season 3.
- Legacy Character: With a name like "Junior", this is pretty much a given.
- Minion with an F in Evil: One explanation for his failure to kill M'gann and his generally benign personality in "Terrors".
- Mythology Gag: The tie-in comic shows that he used to be friends with Artemis Crock. Their comics counterparts had an on-and-off relationship for years, and were married with a daughter before the 2011 reboot.
- Shipper on Deck: Apparently he's one for M'gann and Superboy despite still being a bit bitter over them tricking him in season 1, he thought they would make a good couple and is happy for their engagement.
- Took a Level in Badass: In "Darkest", he's not the wimpy big mouth he was in Season 1. Now, he has some muscle and is more of a threat.
- Took a Level in Kindness: He's much less of a jerk in Season 3, and is genuinely happy when he learns that Superboy is engaged.
- "Well Done, Son!" Guy: His relationship with Icicle Sr. has Cameron doing whatever he can to make his father see him as useful.
- Why Don't You Just Shoot Him?: Was given a perfect opportunity to kill M'gann in Season 2, but had to take the time to gripe about her breaking his heart in Belle Reve first.
- Wisdom from the Gutter: Unknowingly offers some to Superboy about hooking up with Megan. When they meet again in Season 3, Conner actually thanks him for it.
- White Hair, Black Heart: He has white hair and is a psycho.
- Villainous Friendship: Subverted with a disguised Superboy, due to the latter only pretending to be a villain. They do eventually develop a Friendly Enemy relationship though.
The Terror Twins (Tommy Terror and Tuppence Terror)
Voiced by: Yuri Lowenthal (Tommy) and Danica McKellar (Tuppence)
A supervillain sibling duo.
- Alliterative Name: The first letters of their first and last names begin with "T".
- Amazonian Beauty: Tuppence Terror after the Time Skip gets a lot more muscular and no less attractive. Icicle Jr. even hits on her, though he fails.
- Boxed Crook: In the audio play "The Prize", Tuppence is part of Amanda Waller's Task Force X.
- BrotherSister Team: The Terror Twins are always seen working together.
- Canon Foreigner: The writers needed a pair of teenage villains.
- Comic-Book Fantasy Casting: Tuppence was originally designed for the tie-in comic by artist Mike Norton, but Norton's Tuppence looked too much like Shimmer. She was redesigned to look like Gwen Stefani for the cartoon.
- Dark Action Girl: Tuppence is the female half of the twins and is just as psychotic and strong as her brother.
- Nigh-Invulnerable: They can take beatings from Superman.
- Shout-Out: The names Tommy and Tuppence are definitely a reference of Agatha Christie's Tommy and Tuppence but they have nothing else in common.
- Siblings in Crime: Twin criminals who are never far apart.
- Super Strength: Both of them.
- Top-Heavy Guy: Tommy Terror after the Time Skip.
- Zettai Ryouiki: Tuppence. Pre-Time Skip she wore a skirt and stockings. Post-Time Skip she wears hot pants and stockings.
The Injustice League
The Injustice League is a supervillain team that is an evil counterpart of the Justice League.
- Disc-One Final Boss: Deliberately set up by the Light to take the fall for their crimes.
- The Smurfette Principle: They have Poison Ivy.
- Unwitting Pawn: Word of God said some knew they were proxies for The Light while some didn't. Vertigo and the Ultra-Humanite are likely in the former category; the Humanite is an old colleague of the Brain, and Vertigo later has the Light backing his attempt to usurp the throne of Vlatava. The Joker is hinted by Greg Weisman to be in the latter category.
A supervillain with supernatural powers similar to Captain Marvel's.
- Badass in Distress: He's captured along with numerous other heroes and villains in Young Justice issue 21.
- Blood Knight: When Kylstar decides to let them go, he offers a chance to stay and help him win back his homeworld, promising them good treatment and glorious battle. Adam, Major Force and Blockbuster accept.
- Curtains Match the Windows: Black hair and black eyes.
- The Dragon: To Count Vertigo, among the Injustice League.
- Evil Counterpart: To Captain Marvel — They both were granted the same powers from the wizard Shazam, but Captain Marvel uses them to protect Earth, Black Adama uses them to harm.
- Fallen Hero: He was originally supposed to be a hero when the wizard Shazam gave him his powers. Didn't turn out so well. According to Greg Weisman, Black Adam has been considered a hero by some.
- Flying Brick: He's got all the same powers as Captain Marvel.
- He Who Fights Monsters: Along with Vandal Savage and Ra's al Ghul, Black Lightning cites him as an example of this after Geo-Force gives in to the dark side.
- Put on a Bus: In season two. The comic tie-in reveals that he joins Kylstar's posse.
- Super Strength: Adam's physical might exceeds Superboy's.
Voiced by: Brent Spiner (EN), Rubén Leon (Latin American dub)
- Ax-Crazy: Well yeah. It's the Joker.
- Batman Gambit: Implied to have been how he tricked Snapper into revealing the secret location of the Justice League.
- Breaking the Fourth Wall: "Admit it. You can't turn away."
- Curtains Match the Windows: Green hair and green eyes.
- Everything's Better with Monkeys: Uses, of all things, a bunch of crazy green monkeys against the Justice League.
- Evil Laugh: Naturally, though his is more of a dry chuckle in the vein of Cesar Romero than Mark Hamill's gleeful cackle. In fact, he does it after almost every sentence, making it something of a Verbal Tic.
- Fingerless Gloves: Wears gloves without fingers.
- Ink-Suit Actor: The Joker is drawn to resemble a younger version of his VA, Brent Spiner. In fact, his outfit and shaggy hairdo are a direct reference to Spiner's first professional appearance in Night Court (though with The Joker's color scheme, naturally).
- Knife Nut: Has a fondness for switchblades.
- Large Ham: Not as much as usual, but it's still there.
- Lean and Mean: This Joker is quite skinny, bordering frail... but it doesn't make him any less dangerous.
- Mad Hatter: Juggling multiple personalities helps practice multitasking.
- A Mind Is a Terrible Thing to Read: Martian Manhunter's attempt to read his mind totally backfires.The Joker: Scary in there, isn't it?
- Spell My Name with a "The": The Joker.
- Taking You with Me: Tries to kill the Justice League, the Team, and the Injustice League with Joker venom. Fortunately, Doctor Fate possessing Aqualad intervened before anyone died.
- In the comics he is immune, so it might just be a case of him betraying his allies if his immunity carries over to the show.
- Tricked-Out Gloves: In "Revelation", he uses special gloves to control the giant plants.
- Wild Card: After the Injustice League is taken down, Joker just tries to kill everyone.
- Would Hurt a Child: He singles out Robin in battle, which makes sense considering who his arch-nemesis is.The Joker: I've always wanted to carve this bird.
- You Gotta Have Blue Hair: As per tradition, he has green hair.
Poison Ivy (Pamela Isley)
Voiced by: Alyssa Milano
- Evil Redhead: Ivy's red hair is one of her trademarks.
- Green Thumb: She has the ability to control plants.
- Villainous Friendship: Comparatively speaking. In the comics, she hates Joker with a passion (due to his treatment of Harley Quinn and his generally being a raging lunatic) but here she shows no sign of disliking him and even compliments his multitasking while controlling the plants.
Count Werner Vertigo
Voiced by: Steve Blum
Count Werner Vertigo is a supervillain and both a member and the field commander of the Injustice League. He is a member of the royal family of Vlatava.
- Adaptational Badass: Goes from joke villain to leader of the Injustice League. His return in Outsiders also shows this, being a man who genuinely spells trouble and terror in others, while also being a calculating mastermind.
- Ambition Is Evil: Count Vertigo's villainy is driven by his desire to become King Vertigo. He's prepared to murder his own niece or help Baron Bedlam take over Markovia in order to make that happen.
- Aristocrats Are Evil: Count Vertigo is a murderous supervillain and would-be usurper to the royal throne of Vlatava, who dismisses commoners as being "peasants". And appropriately enough, in Season 3 he teams up with another evil nobleman, Baron Bedlam of Markovia, helping each other to seize power over their respective countries.
- Bad Boss: As part of Bedlam, he constantly threatens his underlings with death when things go wrong.
- Boring, but Practical: His only power is to disorient people, but it's more than effective against his opponents.
- The Bus Came Back: After being arrested in his second appearance, Count Vertigo returns in Outsiders as a recurring antagonist.
- Cain and Abel: He murdered his own brother, the Vlatavan king.
- Cane Sword: Wields one, which, according to Perdita, is an heirloom of Vlatava's royal family.
- Catch Phrase: "Count Vertigo to you, peasant!"
- The Chessmaster: "Coldhearted" shows him at his finest.
- Clothes Make the Superman: His "vertigo" ability comes from a special piece of headgear.
- Combat Pragmatist: He uses his powers to gain an upper hand in battle.
- Diplomatic Impunity: The reason why he isn't arrested with the rest of the Injustice League, as revealed in "Coldhearted". Unfortunately for him, he loses this as he is tricked by Kid Flash into revealing the truth.
- Engineered Public Confession: Tricked into one of these in "Coldhearted" after the queen presumably had died.
- The Evil Prince: Or rather, an Evil Count.
- Evil Uncle: He tried to kill Perdita, his own niece and the queen of his country, in order to gain the throne for himself.
- Faux Affably Evil: He acts the part of a cultured nobleman, but that falls apart when his plans start to fail.
- Graceful Loser: At least when the Injustice League is defeated, because he knew his diplomatic immunity would keep him out of prison. Not so much in "Coldhearted", where he tries to kill Perdita after having his title and immunity taken away from him.
- Guttural Growler: Vertigo speaks in a deep, gravelly voice that emphasises the vicious personality that exists beneath his affected nobility.
- Hoist by His Own Petard: If he and the Light hadn't gone so far in attempting to kill his niece (including Vandal Savage distracting Kid Flash for 15 minutes), it would not have led to Wally discovering his involvement in the plot and - more importantly - successfully tricking him into confessing his high treason. This leads to Perdita revoking his diplomatic immunity and his being thrown into Belle Reve, which he'd originally avoided.
- Insistent Terminology: He's not trying to murder Perdita...Count Vertigo: It's called regicide.
- Karma Houdini: Thus far, Vertigo has evaded justice for his crimes and is still on the loose.
- Kick the Son of a Bitch: In Season 3, he constantly threatens to kill Dr. Ecks if he screws up. Considering that Dr. Ecks is a Mad Doctor who is also complicit in forcibly transforming innocent kids into metahuman slaves, he doesn't warrant any sympathy.
- Non-Action Guy: Downplayed by the fact that he isn't entirely helpless, but his only power is his ability to induce vertigo on others, which is admittedly strong as he can hold down heavy hitters with it. However, he's a physical normal and doesn't have much in direct combat skills, and relies mainly on leadership, planning, weapons, and others to carry out the heavy lifting. While he can hold people with his power, he's much less skilled at fighting others directly all by himself.
- Smug Snake: Smugly rubs his "victory" in Kid Flash's face, but quickly loses his composure when Perdita is revealed to be alive.
- The Sociopath: He had no qualms about trying to murder his own niece for the sake of power, all while pretending to be concerned over her health. He takes it a step further in Outsiders, where Vertigo has dispensed with any pretensions of nobility, shamelessly participates in (meta)human trafficking of innocent children, and repeatedly threatens to kill his subordinates for any mistake, all so that he can ultimately get the throne he's always wanted.
- Steven Ulysses Perhero: His full name and title are Count Werner Vertigo.
- Touché: To both Wally and Perdita. "Well played, children, admittedly well played."
- They Call Me Mr Tibbs: "Count Vertigo to you, peasant!" (Who let him keep his title, anyway?)
- White Hair, Black Heart: White-blond hair on a man willing to murder his own pre-teen niece to usurp his home country's throne.
- Would Hurt a Child: He plots to kill his own 10-year-old niece in "Coldhearted". Taken even further in Outsiders, when he is revealed to be one of the leaders of Project Bedlam, which is conducting dangerous lab experiments on metahuman children, which have a damn high fatality rate.
Voiced by: Bruce Greenwood
- Beard of Evil: Has a classically evil pointed goatee.
- Evil Sorcerer: He works for Klarion on a spell to split the world in two.
- Evil Sounds Deep: Wotan speaks in a deep, resonant tone that suits the evil sorcerer like a glove.

- Red Eyes, Take Warning: His irises are red with black sclera.
Intergang is an organized crime group led by "Ugly" Mannheim.
Parasite (Raymond Maxwell Jensen)
Voiced by: Adam Baldwin
Parasite is a villain who can absorb powers.
- All Your Powers Combined: Can use any powers that he absorbed at the same time.
- Bald of Evil: No hair? Check. Villain? Check.
- Evil Tastes Good: Describes the powers he absorbs in culinary terms.Parasite (after absorbing Superboy's powers): Mmmm, now that's the full-bodied Kryptonian flavor I love!
- For the Evulz: His supposed reason for destroying Geneva with a "black hole".
- Hoist by His Own Petard: When he leeches off someone, he receives both their powers and weaknesses. This leads to his defeat when he is surrounded by flames after he had absorbed Miss Martian's powers and gains her weakness to fire.
- Meaningful Name: Like a regular parasite, he suck something out of someone else. In this case, powers.
- Power Parasite: Naturally. He can absorb someones abilities by touching them.
- Weaksauce Weakness: Parasite not only takes on the abilities of people but he also absorbs their particular weaknesses as well. He was defeated because he absorbed Miss Martian's weakness to fire.
Bruno "Ugly" Manheim
Voiced by: Kevin Michael Richardson
Bruno "Ugly" Mannheim is the leader of Intergang.
- Beard of Evil: He has a Fu Manchu moustache framing a square chin.
- Informed Deformity: He's not a looker by any means, but he's not really that ugly.
- Jerkass: "Ugly" Mannheim is impatient, aggressive and suspicious. He is also selfish and has no loyalty to his gang as he left Whisper A'Daire behind to be captured as he made his own escape.
- Mind Rape: Shares this fate with A'Daire. The Competitor warrior working with the Light (later revealed as Black Beetle) does this to him, leaving him alive but unresponsive.
- Why Don't You Just Shoot Him??: He asks Desaad why he is taking his sweet time having Infinity Man kill Superboy.
- When he gains control of an element monster, he disregards killing Superboy, because he states that killing a Kryptonian takes too much time and the police were on their way. One wonders why he didn't kill Blue Beetle or the sphere or (seeing as the other two have some thick armor) the wolf, but the police were almost there, and with them the Justice League would come, and Ugly probably couldn't take them all on.
- Younger Than They Look: He's only 23 in Season 1.
Voiced by: Grey DeLisle
A member of Intergang and works closely with Manheim.
- Adaptational Wimp: She has superpowers in the comics, but she's a normal human with advanced weapons here.
- Beauty Mark: Under her right eye.
- Evil Redhead: She has long, red hair and is a member of the criminal organization, Intergang.
- Mind Rape: Shares Manheim's fate. The Competitor warrior working with the Light (later revealed as Black Beetle) does this to her, leaving her alive but unresponsive.
- Pet the Dog: A'Daire felt genuine concern and pity for the golem when he groaned in pain.
BedlamA secret metahuman trafficking syndicate in Markovia.
- Bedlam House: Can be considered as one.
- Superhuman Trafficking: Or in this case, "metahuman trafficking". They're planning to kidnap and enhance people with the metagene, and then sell them off as Mind Controlled Slave Mooks to any government or warlord who will pay, not just on Earth but also to alien planets (such as Apokolips).
- Would Hurt a Child: Under the guise of a children's hospital, they would conduct unethical laboratory experiments on children who have the metagene. And they're not guaranteed to survive or remain human.
Baron Bedlam (Frederick DeLamb)
Voiced by: Nolan North
Baron Frederick DeLamb a.k.a. Baron Bedlam is the brother of Ilona DeLamb-Markov as well as the brother-in-law of the king of Markovia. He is the commander of the security forces of Markovia and is also the head of Bedlam.
- Adaptational Badass: His metahuman powers makes him tough enough to toe-to-toe with the likes of Geo-Force and Superboy, whereas his comics counterpart is strictly a normal.
- Adaptational Species Change: Became a metahuman instead of a Badass Normal like in the comics.
- Arc Villain: He's the main antagonist for the first three episodes of Outsiders.
- Aristocrats Are Evil: Baron Bedlam is a murderous supervillain who plans the assassinations of his own sister and brother-in-law, the Queen and King, with the ultimate goal of seizing control over Markovia. And appropriately enough, he even teams up with another evil nobleman, Count Vertigo of Vlatava, helping each other to seize power over their respective countries.
- Asshole Victim: Given all the vile deeds he's done over the course of the third season, it's hard to feel sorry for him when Brion kills him. In fact, the heroes seemed more concerned about how Brion killed him rather than the fact that he died.
- Cain and Abel: He had both his sister and brother-in-law assassinated as part of his own grab for power.
- Curb-Stomp Battle: Dishes one out to Brion during their first fight....and is on the receiving end when Superboy knocks him on his ass in 5 moves (tellingly Bedlam runs for the door rather than face Superboy again.)
- Cruel and Unusual Death: Brion drowns/burns him to death by shoving lava down his throat until it's coming out of his ears, nose, and eyes.
- Devil in Plain Sight: Downplayed. While he doesn't do anything to encourage it himself, it's obvious that he had the most to gain from the King and Queen's deaths, and so most of the characters suspect him of foul play long before his true colors are revealed.
- Dirty Coward: He has no problem mocking Brion and calling him weak during their rematch yet immediately runs for the door when faced with the prospect of fighting Superboy (someone who has already kicked his ass once).
- Evil Makes You Ugly: As befitting for a two-faced sociopath like himself, he is hiding his true appearance after his own secret metahuman transformation, which turned his skin into stone (he wears a fake skin to cover his changed body). Underneath his charade of being a Reasonable Authority Figure, he is both figuratively and literally a monster.
- Evil Uncle: The uncle of Gregor, Brion, and Tara Markov, who was willing to have his own sister and brother-in-law murdered; kidnapped, experimented on, and sold his niece as a slave to the League of Shadows. Then when his plans take an unpredictable turn, he tries to have his nephew framed for his crimes (see below).
- Frame-Up: After learning that Brion was captured in the hospital and gained superpowers, he tries to cover his tracks by framing his own nephew for the metahuman trafficking conspiracy. It soon falls apart though when Bedlam reveals his own powers, which leads to Gregor correctly deducing that his uncle was responsible for all those crimes.
- Hate Sink: Stands out as one of the vilest and most repulsive villains in the series. Not only is he behind the metahuman trafficking of children, he has his own sister and brother-in-law murdered, and their children turned into metahumans.
- Hypocrite: HOO YEAH! He paints himself as a reasonable authority figure while orchestrating the not only the murders and/or kidnapping of his relatives but running a mass trafficking ring that kills enough children to warrant mass graves. He also makes bigoted comments against Quaraci while hiring one to kill his sister and brother in law and calls Brion weak while running from a stronger opponent.
- Kick the Dog: Calls the Markovs "orphans" when HE was the one who orphaned them.
- Knight of Cerebus: While the series always had its fair share of dark moments in the first two seasons, DeLamb's vile actions quickly establishes the Darker and Edgier tone of the third season.
- Know When to Fold Them: The first thing he does when he sees Superboy (the guy who kicked his ass in single combat) with backup is run for the door. Given how badly Superboy kicked his ass the first time they fought it's a smart move on his part.
- Out of Focus: Frederick is showcased as a major villain for Season 3, but gets shoved under the rug in-universe and out when Granny Goodness suddenly enacts her plan mid-season and becomes a much more pressing threat. Any real focus on Frederick doesn't return until the season finale, which is also when he dies.
- Politically Incorrect Villain: Implied. He hired a Quraci assassin as a pretense to screen all Quraci refugees for the metagene, and empowered the military to use "extreme tactics" to ensure their cooperation. While it could just be a scheme to kidnap more metahumans, it comes off as being racist (especially given the rampant xenophobia against Quracis in Markovia).
- Related in the Adaptation: The brother of the Queen of Markovia, and therefore the uncle of Gregor, Brion, and Tara Markov.
- Significant Anagram: "Bedlam" is an anagram for his real surname, "DeLamb". Nightwing, who spent hours second-guessing the identity of the culprit, is practically kicking himself for not seeing it sooner.
- Straw Hypocrite: The stuff he does behind closed doors is the opposite of what he pretends to stand for in public.
- Strong and Skilled: In comparison to his nephew Brion, Bedlam is able to fight more effectively with his meta abilities. Unfortunately for him, this is what allowed his other other nephew to see through his lies.
- The Sociopath: He pretends to be a Reasonable Authority Figure who's just trying to do what's best for his country's security and his family's safety; when he is really a power-hungry tyrant who kidnaps innocent children, and shows no real remorse over backstabbing his own family members in the worst ways possible. He is also a Consummate Liar who tries to pin his horrible crimes on his innocent nephew, and almost got away with it until the heroes exposed him.
- Taken for Granite: Has undergone metahuman experiments on himself to gain a rocky stone-like body. He wears a false skin to hide his transformation.
- The Worf Effect: While soundly able to defeat the recently triggered, Geo-Force, Bedlam gets easily defeated by the more experienced Superboy.
- Would Hurt a Child: Frederick DeLamb leads the child trafficking conspiracy in Markovia, and is implied — and later confirmed — to be responsible for his own niece's disappearance as part of that conspiracy.
- You Have Outlived Your Usefulness: He shoots the metahuman assassin he hired to kill his sister and brother-in-law in the back, after he had served his purpose.
- The Light does this to him in Nevermore, when Ambassador Baazovi influences Brion into killing him to turn Geo-Force against the heroes.
Dr. Simon Ecks
Voiced by: Troy Baker
Dr. Simon Ecks is the head geneticist at Bedlam.
- Adaptational Superpower Change: In the comics, he can create a single astral-projected duplicate of himself which has various superpowers, here he has Self-Duplication instead.
- Bitch in Sheep's Clothing: Ecks plays the part of the kindly physician, but at his core, he's a heartless criminal who has no qualms about subjecting children to a potentially lethal process and selling them into slavery if they survive.
- Comic-Book Movies Don't Use Codenames: He's never referred to as "Doctor Double X", likely due his different power set that would've made it an Artifact Title, and the inherent ridiculousness of the name itself, along with the fact that there is already a character named Dubilex (pronounced Double-X) in the show.
- Composite Character: Simon Ecks with his new power set while being an amoral scientist, brings to mind the Firestorm villain Multiplex.
- Dirty Coward: The main Simon hides and creates clones to fight for him. Understandable as once the main Simon is down, the clones will disappear.
- Mad Doctor: He pretends to be a well-meaning employee of a children's hospital, but is really using his patients as guinea pigs.
- Mad Scientist: He's an amoral geneticist who performs cruel medical experiments on oblivious children.
- Me's a Crowd: He has the metahuman ability to create clones of himself, not unlike Multiplex or Riot.
- Self-Duplication: He can do this with his superpowers. If the main Simon is knocked unconscious, all of the clones will disappear.
- Would Hurt a Child: He has experimented on numerous children (such as Ana and Otto Von Furth) to activate their metahuman powers, with many of them failing to survive the process.
Voiced by: ???
Jaculi was a Quraci terrorist hired by Baron Bedlam to assassinate the King and Queen of Markovia.
- Adaptational Badass: In the comics, Jaculi was a Joke Character who couldn't catch a break even after his hilariously embarrassing death at the hands of Captain Boomerang. While he dies just as quickly in the show, he does manage to accomplish quite a bit in his short time on-screen.
- Knife Nut: He stabs the King and Queen to death with a blade, just after cutting his way through several of their bodyguards.
- Middle Eastern Terrorists: Invoked; he's a Quraci assassin who killed the monarchs of Markovia. Bedlam, who was the real mastermind behind the assassinations, was really trying to secretly thwart the King's and Queen's efforts to combat his illegal human trafficking; and after the incident, Bedlam claims that he'll monitor and profile all Quraci refugees in Markovia who might be metaumans.
- Professional Killer: He commits regicide on orders from Bedlam.
- Smug Smiler: Cracks quite a few smug smirks as he slaughters the King and Queen and brutalises the royal guards.
- Super Speed: He has this power, allowing him to easily evade the royal palace guards. However, he wasn't quick enough to avoid getting shot by Bedlam.
- You Have Outlived Your Usefulness: After Jaculi murders the King and Queen, Bedlam shoots him dead in order to ensure that he won't end up revealing the truth about who really planned the assassinations.
Plasma (Ana Von Furth)
Voiced by: Grey DeLisle
A 14-year-old Markovian girl with a terminal heart disease, who gets abducted in the Markovburg Children's Hospital. Her powers are forcefully activated, turning her into a monstrous lava creature.
- Anti-Villain: She's not evil at all, just an innocent child who's being forced to fight for the bad guys against her will.
- Attack Its Weak Point: Plasma's heart remains intact in her otherwise liquefied form. A shock from Black Lightning meant to incapacitate her proved fatal, as her heart was already weak before her transformation.
- Blob Monster: Resembling a being made of lava, tar, and blood.
- Body Horror: Her human heart is visible, floating inside her translucent body with bubbles around.
- Composite Character: Both Otto and Ana Von Furth are based on Plasmus, however their overall design and powers, and the fact that Ana was forced to fight alongside Parademons which are Apokoliptians, makes them a composite of Brimstone; an artificial being created by Darkseid with the same Touch of Death powers.
- Sacrificial Lamb: She is accidentally killed by Black Lightning, when he fires an electric bolt that overwhelmed her weak heart. Her death and the subsequent reveal that she was an innocent human kid disturbs him deeply.
- Slave Mooks: She was placed under Mind Control and forced to fight for Darkseid.
- Touch of Death: She instantly incinerates an unfortunate Rannian soldier.
- Tragic Monster: She's forced to become a guinea pig in a lab experiment, which turns her into an inhuman creature, and is then forced to fight against her will as part of Darkseid's army during an invasion of Rann.
- Transformation Horror: She became a hideous lava-like Blob Monster, with a visible heart floating inside.
- Was Once a Man: She doesn't look human anymore after her metagene was activated.
Plasmus (Otto Von Furth)
Voiced by: Yuri Lowenthal
The older brother of Ana Von Furth. After his younger sister's disappearance and death, he was also experimented on and forced to become another similar monster with the same powers.
- Adaptational Heroism: Much like the show's Neutron or even his incarnation in the Teen Titans cartoon, this Plasmus isn't in control of himself, whereas his comic counterpart was murderous and even expressed jealousy at Chemo's powers in Infinite Crisis.
- Adaptational Nationality: In the comics Otto Von Furth was German, here he's a Markovian.
- Age Lift: Otto is a teenager like in the Teen Titans cartoon, but in the comics he was an adult.
- Anti-Villain: Just like his little sister, he's an unlucky kid who was conscripted into serving as a disposable minion of the villains.
- Attack Its Weak Point: Plasmus's human brain remains intact in his otherwise liquefied form. A farmer with a rifle easily kills him by shooting his brain.
- Blob Monster: Resembling a being made of lava, tar, and blood.
- Body Horror: His brain is visible, floating inside his translucent body with bubbles around.
- Composite Character: Both Otto and Ana Von Furth are based on Plasmus, however their overall design and powers, and the fact that Ana was forced to fight alongside Parademons which are Apokoliptians, makes them a composite of Brimstone; an artificial being created by Darkseid with the same Touch of Death powers.
- Death by Adaptation: He dies in the third episode, while Plasmus in the comics has been a foe to the Teen Titans for many years.
- The Dog Bites Back: As soon as he's free from Bedlam's control, Plasmus attacks Dr. Ecks. Luckily for Ecks, it was just one of the not-so-good doctor's duplicates.
- Hope Spot: Black Lightning makes sure to non-lethally defeat Plasmus, by freeing him from Count Vertigo's mind control. Unfortunately, just when Otto helps the Outsiders finish their fight, he gets shot and killed by an armed farmer who mistook him for an evil monster, thus joining his sister in premature death.
- Roaring Rampage of Revenge: He goes on a short-lived one, after his mind-control chip was destroyed by Black Lightning.
- Slave Mooks: He was placed under Mind Control and forced to fight for Count Vertigo.
- Touch of Death: Count Vertigo has stated that nothing can survive the touch of Plasmus (unless you're Kryptonian or a metahuman with healing abilities).
- Tragic Monster: He took his sister to the hospital to have her heart condition treated, only for her to (apparently) die and then disappear. When he confronts the doctor responsible for it, he too is forced to share her fate of becoming an inhuman creature, and an expendable pawn for the bad guys.
- Transformation Horror: He became a hideous lava-like Blob Monster, with a visible brain floating inside.
- Was Once a Man: He doesn't look human anymore after his metagene was activated.

Voiced by: Jeff Bennett
Abra Kadabra is a faux magician.
- Adaptational Wimp: Perhaps due to being overshadowed by Klarion, he's substantially less of a threat than in the comics, where he's almost always the Big Bad when he shows up.
- Beard of Evil: Works for the Light and sports a goatee beard.
- Carpet of Virility: He typically wears a poet shirt that exposes his hairy chest.
- Demoted to Extra: Things are very, very personal between him and Wally in the comics, but here he's treated as just another enemy.
- Electric Torture: Seems to be a favorite of his.
- Magic from Technology: He's actually a guy from the future using really advanced technology and just pretending it's magic.
- Spanner in the Works: One of the main reasons Klarion recruited him to help get the helmet of Nabu was because Kent Nelson would be less prepared for a fake magician than a real one.
Voiced by: Peter MacNicol
Amazo is an android built by Professor Ivo.
- All Your Powers Combined: Thanks to his Power Copying abilities.
- Blow You Away: Copied from Red Tornado.
- Calling Your Attacks: He has to say the name of whatever Justice League member whose powers it has copied before it can use them. Given that Amazo is a robot, and that this was his first ever appearance within the continuity of the show, this is more understandable than most examples. Although this provides a clue to Amazo's weakness, and the team use that to defeat it.
- Discard and Draw: While this version of Amazo keeps the powers he copies, he thankfully can only use one ability set at at time. This is possibly justified as this is the first Amazo Ivo created.
- The Dragon: To Professor Ivo, for however long it lasted.
- Implacable Man: He's really hard to stop, and he never slows down until he completes his objective.
- Intangible Man: Copied from Martian Manhunter.
- Lightning Bruiser: Thanks to Superman and Flash's powers.
- Machine Monotone: Everything he says is in a low-pitched, mechanized version of Ivo's voice.

- Butt-Monkey: He tried to rob a bank while a bunch of heroines were having a Bridal Shower across the street.I'm completely doomed, aren't I?

Mr. Freeze (Victor Fries)
Voiced by: Keith Szarabajka
Mister Freeze is a cold-themed villain, and an enemy of Batman and Robin.
- Bald of Evil: Well it is Mr. Freeze.
- Creepy Monotone: As is to be expected, Freeze speaks in a cold, steady voice, although he does shout a bit in his staged attack on Icicle Sr.
- Evil Genius: Of the ice villains. He had the foresight to remove his collar in Belle Reve and managed to retrace the steps of the one who reactivated them.
- An Ice Gun: His trademark freeze gun. Unlike Captain Cold it actually does do ice.
- An Ice Suit: He can't survive in normal room temperatures. After Superboy shatters his helmet, Freeze is forced to encase himself in ice to survive.
- Icy Blue Eyes: They fit with his ice theme.
- The Starscream: Subverted. While in Belle Reve, Freeze tries to usurp Icicle Sr. It's just a ploy to escape however. Though, Icicle Jr. didn't know that.
- Weaksauce Weakness: Can't survive outside of subzero temperatures, that means when his dome is shattered, he's beaten.
Icicle Sr. (Joar Mahkent)
Voiced by: James Remar
Icicle Jr.'s father and an inmate at Belle Reve.
- Abusive Parents: He is dismissive of his son, only caring about said son's presence when he can be of use to him.
- Action Dad: He was a renowned criminal and abusive father to his son.
- Badass Normal: He's a big man and looks physically fit, but has no apparent special powers, yet he is not only imprisoned at a jail dedicated to housing "super criminals", but within Bell Reve, he is the widely-recognized "capo" among the supervillain prisoners.
- Beard of Evil: He has a grey beard.
- Composite Character: As the father figure Junior is trying to impress, he takes elements from his son's Parental Substitute The Wizard (Joar himself being long dead in the comics).
- Graceful Loser: In mid-September of 2010, Senior initiated a mass break out attempt with smuggled technology with the help of Captain Cold, Icicle Jr., Killer Frost, and Mister Freeze. Despite not escaping, Senior and Hugo Strange were satisfied with accomplishing multiple objectives, in part for the Light.
- Human Popsicle: Word of God is that he spent 35 years "on ice", explaining why he's Older Than He Looks.
- An Ice Person: Icicle Sr. is a supervillain who uses cryokinetic technology.
- Jerkass: Mahkent is a supervillain, lousy father, and generally a nasty piece of work to anyone who's not on his good side.
- Older Than They Look: According to Word of God, he's really 85 years old, but is physiologically 50.
- Spared by the Adaptation: In the comics the first Icicle died in Crisis on Infinite Earths before his son took up the mantle.
Killer Frost (Crystal Frost)
Voiced by: Sarah Shahi ("Terror"), Vanessa Marshall (Legacy)
An ice-powered supervillain.
- Absolute Cleavage: Her normal outfit shows off a nice bit of her chest.
- Amazing Technicolor Population: Justified. She was exposed to an cyrokinetic project that gave her ice powers.
- Composite Character: Her sociopathic attitude and costume are based on the second Killer Frost, Louise Lincoln.
- Curtains Match the Windows: Blue hair and eyes.
- For the Evulz: Tries to kill a prison guard solely for the entertainment value.

- You Gotta Have Blue Hair: She has blue hair.
Mister Twister (Bromwell "Brom" Stikk)
Species: Robotic suit
Voiced by: John de Lancie
A robotic suit created by Professor T.O. Morrow.
- Adaptational Badass: In the comics, he's rarely ever a problem. On the show, he repeatedly curbstomps the team.
- Blow You Away: He's a wind generating robot like Red Tornado.
- Deadpan Snarker: While in the Mister Twister suit, Stikk is definitely this; his powers give his ego a significant boost. Possibly the best Insult Backfire he's given was to Robin, after he states his unnerved attitude at the Team's usage by the League:Stikk (as Mister Twister): Have you no adult supervision? I find your presence here quite...disturbing.
Robin: Well, we hate to see you disturbed, so let's see if you're more "turbed" once we kick your can!
[Stikk proceeds to curb-stomp Superboy, Miss Martian, Aqualad, and Robin in quick succession]
Stikk: Indeed. That was quite "turbing". Thank you.
- Even Evil Has Standards: By his own admission, he's disturbed that this version of the Justice League would use their sidekicks as Child Soldiers.
- Evil Sounds Deep: Mister Twister's processed voice is very deep, contrasting the medium range of Stikk's natural voice.
- The Man Behind the Curtain: The real Stikk was nowhere near Happy Harbour while Mister Twister fought the Team.
- Meta Mecha: It's a Powered Armor, but for safety concerns the "human" pilot is an android himself.
- Mistaken Identity: In his initial appearance, Miss Martian can't read his mind, leading the team to mistake him for a disguised Red Tornado giving them a Secret Test.
- Powered Armor: The Mister Twister suit, initially believed to be an android, is later revealed to be a suit worn by a robotic duplicate of Stikk. Morrow apparently convinced Stikk not to wear the suit himself, much to Stikk's relief after Miss Martian destroyed his double.
- Scarf of Asskicking: The Twister armor wears one.
- Screw This, I'm Outta Here!: The real Stikk ditches the base when Red Volcano goes rogue, the android is annoyed that his first real victim got away.Red Volcano: Where is Stikk?!
- Shock and Awe: Unlike Red Tornado, Mister Twister has electrical powers as well as wind-generation.
- Undying Loyalty: After the Red Volcano fiasco, Brom can be later seen at the aged Morrow's bedside.
- Villain Has a Point: As he points out, the team is composed of children, hence the League are using their sidekicks as Child Soldiers.

Professor Anthony Ivo
Voiced by: Peter MacNicol
Professor Anthony Ivo is a criminal scientist.
- Affably Evil: He's fairly polite and well-mannered.
- Deadpan Snarker: Makes a number of snarky remarks to Superboy.Ivo: Oh, did that strike a nerve? Amazo, strike a few more!
- Evil Redhead: A Mad Scientist with red hair.
- Fun with Acronyms: Lampshaded when he comments that it's hard to find an acronym for monkey.
- I Shall Taunt You: Continually boasts of Amazo's power as it pummels Superboy. Later, in Belle Reve, Ivo (or, at least, the android Ivo left to cover for him) took the time to taunt the comatose T.O. Morrow over his condition.
- Mad Scientist: Creates deadly robots for the purposes of fighting the Justice League.
- Robot Master: He built Amazo, the MONQIs, and robot double of himself.
- Smug Snake: He's smug and confident while Amazo beats down the Team, but his composure falls apart quickly when Superboy starts attacking Ivo himself as part of a plan to destroy the android.
- Villain: Exit, Stage Left: When the Team defeats Amazo, Ivo manages to escape offscreen.
Professor Hugo Strange
Voiced by: Adrian Pasdar
Professor Hugo Strange was the resident psychiatrist at Belle Reve Penitentiary, Amanda Wallers apparent second-in-command, and secretly, an agent of the Light. After Waller's ousting, he became Belle Reve's new acting warden.
- Affably Evil: Despite being the Light's mole in Belle Reve, Strange is courteous enough.
- Bald of Evil: Endemic to the character.
- Beard of Evil: As always, Strange wears a chinstrap beard.
- Cardboard Prison: Belle Reve is one thanks to him. The Light installed him so they could smuggle anyone they needed out at will.
- The Mole: Serves as the Light's mole in Belle Reve prison.
- Mole in Charge: Which was the whole point of the attempted breakout.
- Morally Ambiguous Doctorate: Subverted. While he does have a doctorate, he's always referred to as Professor Strange.
- Scary Shiny Glasses: Though they appear to be tinted in this version of the character.
- The Shrink: Plays a Type 2 until The Reveal.
Professor T.O. Morrow
Voiced by: Jeff Bennett
Professor T.O. Morrow is a genius scientist who created three superhero androids to infiltrate and destroy the Justice Society of America.
- Dark Lord on Life Support: This is the case for the real T.O. Morrow, who is extremely old and in a coma.
- Evil Old Folks: Morrow is 100 years old, and even though he can no longer act on his own, he continues his efforts against the heroes.
- For Science!: Morrow's primary motive in creating more powerful androids seems to be for the sake of advancing robotics technology.
- Graceful Loser: In "Welcome to Happy Harbor", he doesn't get angry over the destruction of Mister Twister, taking solace in the knowledge that his tracking program worked well enough to at least narrow down Red Tornado's location.
- Hoist by His Own Petard: No more "Pinocchios!". It Makes Sense In Context.
- All his Red androids went horribly right. The first three, designed to infiltrate the Justice Society of America, became genuine heroes and turned against him, and Red Volcano, meant to have no humanity, decided that Morrow was obsolete and turned against him.
- The Man Behind the Man: Or the man behind the man behind the robot behind the robot. No, really.
- According to "Humanity", the T.O. Morrow we met onscreen is actually an android copy created by the original human T.O. Morrow. So, this T.O. Morrow is actually The robot behind the man behind the robot behind the robot. Could this get any more convoluted? Actually yes. If the original human T.O. Morrow is also involved in these plots, then that guy is The man behind the robot behind the man behind the robot behind the robot.
- Robot Master: He built the Red androids and a robot double of himself
- Robotic Reveal: The T.O. Morrow we met onscreen is actually an android. The real and human T.O. Morrow appears in the end of "Humanity" as an old bedridden man.
The Riddler (Edward Nigma)
Voiced by: Dave Franco ("Terrors", "Usual Suspects"), Jason Spisak (Legacy)
The Riddler is a supervillain with a penchant for charades and riddles. Despite not being taken seriously by other criminals, he is an agent of and strategist for the Light.
- All of the Other Reindeer: Gets no respect in Belle Reve.
- Cool Shades: Triangular green glasses with a purple frame.
- Crouching Moron, Hidden Badass: The only criminal in Belle Reve who actually escaped.
- Evil Counterpart: In a way, he's one to Robin I/Nightwing. They're both clever planners, although while this isolates Riddler and makes him a minion, it's what makes Dick a leader. There's also the way they both play around with language, though Dick outgrows his backformations as he grows up, with a few catching on in his friend group as in-jokes, while The Riddler childishly keeps using riddles to annoy people. Dick is also the one who solves the riddle in "Usual Suspects," and is the set leader of Alpha Squad during Riddler's turn as a level boss in Legacy.
- Insufferable Genius: The other cons in Belle Reve find Nigma extremely annoying.
- Sissy Villain: His lisp gives off this impression.
- Smug Snake: Boasts of his position as the Light's strategist, but he goes down easily to Robin.
- Spell My Name with a "The": Known as "The Riddler".
- Speech Impediment: Has a slight lisp.
- Underestimating Badassery: Despite getting no respect whatsoever from his fellow convicts, the Riddler was the only one to actually escape in Icicle Sr.'s prison break scheme.
