The cruel dictator of War World. He gains amusement from watching others fight in his arena, which he captures from around the galaxy to become gladiator slaves. He is deposed by Superman following his experience on War World but comes to Earth later in order to have his revenge against the Man of Steel.
- Amazing Technicolor Population: The color of his skin is sickly pale yellow.
- And I Must Scream: The Justice League trap him in his own dream creating plant. Not exactly that bad of a deal as far as he is concerned as he is living his perfect world but if he ever wants to leave it it'll be like tearing his own arm.
- Authority Equals Asskicking: He's a dictator strong enough to throw down with Superman. This is implied to be the main reason his men put up with him, they don't like him but can't do anything about him.
- Bad Boss: He has no respect for his underlings and they will insult him behind his back.
- The Bad Guy Wins: Subverted. He only thinks that he wins.
- Bald of Evil: He is completely bald.
- Bread and Circuses: His empire drew obvious parallels to the Roman Empire. J'onn J'onzz finds out there's mass unemployment and poverty, but people are kept entertained by the gladiatorial games.
- The Caligula: He essentially used his power as a dictator to amuse himself with no concern whatsoever for the people under his rule.
- Creepy Monotone: As played by Eric Roberts.
- Darker and Edgier: By the time of his second appearance, he's a much more menacing foe than he was during his first. This is even reflected in his color-scheme with a darker shade of purple for his costume.
- The Dreaded: Everyone on War World is afraid of him. His gladiators consider it suicide to cross him and his men will insult him behind his pack, but are quick to cower in his presense.
- Evil Cannot Comprehend Good: He assumed that Superman would be envisioning himself as ruler of the universe in the Lotus-Eater Machine. Instead Superman is just living a peaceful life with his family on Krypton - no special powers, no constant pressure to save the day...
- Evil Sounds Deep: He sounds more like a demon when he speaks instead of an alien.
- Galactic Conqueror: With a bit of President Evil mixed in.
- Genius Bruiser: This version was usually portrayed as an intelligent, if vain conqueror, who was more than capable of out thinking his adversaries.
- He-Man Woman Hater: Presumably, his misogyny was added so that he could Poke the Poodle - even though he was already kicking a kennel's worth of dogs.
- Hoist by His Own Petard: Trapped in his own dream creature.
- Loves the Sound of Screaming: Implied. As the camera zooms in on his smiling face after he's been trapped in his own Lotus-Eater Machine, we hear the sound of distant screams.
- Modest Royalty: For the murderous dictator of an entire planet, he doesn't dress all that fancy.
- Nigh-Invulnerability: The League couldn't defeat him by normal means, so they ended up trapping him in the dream world.
- When Wonder Woman punches him twice, she hurts her hands far more than she does his face.
- In Superman's case, it's more like he wouldn't kill him, though he came close - He outright caved his face in during his Roaring Rampage of Revenge and would've dealt the death blow had he not noticed the statue of his parents, and come to his senses.
- Politically Incorrect Villain: In his second appearance, he is quite demeaning towards Wonder Woman.
- Purple Is Powerful: His outfit incorporates a lot of purple.
- Red Eyes, Take Warning: He has pure red eyes with no pupils.
- Roaring Rampage of Revenge: His motivation in "For The Man Who Has Everything."
- Slasher Smile: He loves killing helpless enemies.
- Smug Snake: Mongul is smart, but very full of himself, and his tendency towards toying with his victims causes him problems.
- Smug Super: Constantly shows off is superior strength.
- Super Strength: One of his powers.
- Technicolor People: He's lemon-colored.
- Took a Level in Badass: His powers didn't necessarily increase, but in "For The Man Who Has Everything", he is infinitely nastier and more conniving than he was as the stereotypical space tyrant of "War World".
- Would Hit a Girl: Against Wonder Woman. In Batman's own words, "He's killing her."
Despero was once a Kalanorian exile due to his third eye, who, after encountering the Flame of Py'tar, became ruler of Kalanor and built an empire, bent on galactic conquest. Only through the intervention of the Justice League and the Green Lantern Corps were his plans halted.
- Adaptational Dye Job: Despero's skin color in the comics had a pink-orange shade. In this series, his skin color was changed into a shade of purple in order to differentiate him from Katma Tui.
- Adaptational Wimp: Believe it or not, in spite of his great power here, he's this compared to his comic book counterpart who was able to battle the likes of Superman, Wonder Woman, Captain Marvel, and Power Girl all at the same time and manhandle all of them at once. In the show, a single Green Lantern like John Stewart can injure him and give him a more-or-less even fight.
- All of the Other Reindeer: His backstory before he became a conquering prophet. His third eye in the middle of his forehead is what sets him apart from the rest of his kind.
- Dark Messiah: Despero sees himself as The Chosen One to the Flame of Py'tar, and with its influence, conquered his planet - and had sights on controlling the galaxy.
- Death Equals Redemption: Despero is stripped of his powers and consumed by a tree when the Flame of Py'tar is freed from its prison. But he finally sees what Py'tar's true vision of paradise was and finds it to be beautiful as he calmly accepts his fate.
- Disability Superpower: Well, it's not exactly a "disability", more like a deformity, but his Third Eye made him an outcast among his kind, and he now uses it to project the Flame of Py'tar.
- Disney Villain Death: An interesting variation: After the will of the Flame of Py'tar is freed, it raises a tree to ensnare Despero, then drags him underground. Despero reacts rather peacefully in his last moments.
- Evil Overlord: He conquered his own homeworld and intends to spread his will upon other planets.
- Evil Sounds Deep: What do you expect when he's voiced by Keith David?
- Freudian Excuse: His third-eye deformity caused him to be banished into the wasteland where he is frequently targeted by bandits and criminals. The Flame of Py'tar saved Despero one day and infused him with its power in the hopes that he would bring paradise back to Kalanor. But the years of being an outcast had hardened Despero's heart and he instead used that power to impose his will upon others and create a "paradise" empire.
- From Nobody to Nightmare: Was nothing more than a mutated peasant on the desert planet Kalanor; before long he was its Evil Overlord controlling an army so dangerous it threatened the Green Lantern Corps.
- The Fundamentalist: A religious true believer who wishes to spread his faith across space. He consider himself the prophet of the Py'tar, and his wars of conquest a holy mission.
- Galactic Conqueror: A conqueror of entire planets, starting with his own.
- Large Ham: He's the leader of religious army who talks with all the prose you would expect, and he's voiced by Keith David
- Red Right Hand: An in-universe version, his third eye made him a social pariah and eventually an outcast.
- Rogues Gallery Transplant: Sort of. While in the comics he is a general threat to the entire Justice League, he reserves a deep amount of hatred for J'onn, who had handed Despero his ass several times, to the point where could be legitimately considered his Archenemy. Here, J'onn never even interacts with him, and it's instead Green Lantern John Stewart who he battles repeatedly.
- Scary Dogmatic Aliens: Leads a fanatical army called "Legion of the Third Eye" which, through the "Flame of Py'tar" starts conquering solar systems for him to rule.
- Super Empowering: After his contact with the Flame of Py'tar, he became a Flying Brick, in addition to Mind Control powers, Mind over Matter and Eye Beams. He can also bestow this ability to his army through Py'tar as well.
- Third Eye: Was treated as an outcast for it. After his contact with the Flame of Py'tar, it opened. He can also shoot Eye Beams through it.
Draaga was once the undefeated champion of War World.
- Anti-Villain: Type IV. He only killed his enemies to ensure he had a homeworld and the only reason he wants revenge on Superman is due to a conflicting code of honour.
- An Axe to Grind: His weapon of choice as a gladiator of War World.
- The Good King: It's implied that he ends up administrating War World, at least temporarily, after Mongul is deposed. It is later confirmed in the novel "Wild at Heart" that he has become War World's ruler.
- HeelFace Turn: How much of a heel is debatable but he does go from wanting to pound Superman for not killing him to pounding Mongul for threatening his homeworld.
- I Did What I Had to Do: He has fought and killed an unknown but large number of total strangers: his homeworld's survival was at stake.
Hro Talak is the commander of a large Thanagrian fleet that appears on Earth to shoot down an invading Gordanian cruiser. He is also Shayera's fiancée. Despite his claims that he wishes to build a force field around the planet to protect it from Gordanian assault, he actually wishes to build a hyperspace bypass to allow his fleet to strike at the Gordanian homeworld before the Thanagarians lose the war. Kragger is his second in command, while Paran Dul is a lieutenant.
- Adaptational Villainy:
- Hro Talak's willingness to blow up the Earth to help Thanagar is why he's not Katar Hol.
- Somewhat averted with the Thanagarians as a whole, as the shows depiction is pretty accurate to the Hawkworld era interpretation of Thanagar.
- Ambiguously Gay: While never outright confirmed, several scenes strongly imply that Kragger is romantically attracted to Hro and views Shayera as competition. The most obvious instance is when Martian Manhunter reads his mind, and Kragger's innermost desire is illustrated as a statue of him and his leader next to Hawkgirl's shattered bust.
- Anti-Villain: Hro is an honorable man only trying to do what is best for his people. The trouble is that he's completely unwilling to come up with any kind of compromise, nor moral enough to Take a Third Option (as noted by Shayera).
- Bare Your Midriff: Paran Dul wears an outfit that shows off her toned stomach.
- Butt-Monkey: Kragger. He's constantly getting chewed on and ends up in a state of catatonia after Martian Manhunter forcefully reads his mind.
- Canon Foreigner: Hro Talek and Paran Dul were created exclusively for the series.
- Crazy Jealous Guy:
- There are a few hints that Kragger's devotion to Hro are not entirely platonic and it surprised the writers that so few people picked up on the imagery in his inner world when J'onn forcibly read his mind. His own unrequited feelings are used against him when he too easily buys into Vixen's story about resenting Shayera for being competition, a position he empathizes with too much.
- Hro himself is largely an honorable man, but his experiences have twisted him such that he can't separate Shayera's heroism from her attachment to John Stewart. As such, he grows quite murderous towards the latter when he didn't have to be competition in the first place. She made it quite obvious that if it were just him against John, she'd pick him.
- The Chew Toy: Kragger. From getting knocked out by his own leader to Martian opening his mind, he gets more humiliating moments than any other Thanagarian on screen.
- Disney Villain Death: Kragger is killed after Shayera destroys his robot suit, sending him free falling from the sky.
- Does This Remind You of Anything?: Having the last straw of Shayera's unwillingness to cooperate and her fraternization with John Stewart, Hro fights her while yelling that he gave everything to her. His voice actor even says that he felt uncomfortable recording that scene due to his views on domestic violence.
- Equal-Opportunity Evil: The Thanagarians have plenty of women among their troops, several of whom hold positions of authority.
- Fallen Hero: From the perspective of Shayera Hol, Hro is a noble and brave man who suffered under captivity, being tortured into extremism and fully accepting the directives of the Thanagarian council, even hiding it from Shayera, considering the destruction or Earth to be a small price to pay for victory.
- Flight: They all have self powered flight.
- Good Scars, Evil Scars: When Hro's mask comes off, we see the scars from where he was tortured. We also learn how far he's willing to go to save Thanagar.
- Graceful Loser: Upon the destruction of the Bypass, Hro Talak immediately rejects any suggestion of revenge against Earth or the Justice League, or even John and Shayera. They were defeated, and ruining the Earth wouldn't accomplish anything. He is still mad about Shayera's betrayal, though.
- Heroic Sacrifice: Hro Talak dies taking out the Gordanian flagship and the much larger Gordanian fleet surrounding it when it explodes. He allows time for some of his men to escape and makes the Gordanian victory a rather Pyrrhic one.
- Jerkass: Kragger and Paran Dul are rather unpleasant people even before taking into account that they're actually villains. They see themselves as superior to not only Earth but also to Martians like J'onn J'onzz and Kryptonians like Superman.
- Jerkass Has a Point: From their perspective, Shayera siding with Earth led to the Thanagarians' loss in their war with the Gordanians when the Bypass would have made victory certain. Their only alternatives was subjugation under the Gordanians, whereas the alternative they are giving Earth is extermination.
- Large and in Charge: Hro is largest and tallest of all Thanagarians and is in charged of the fleet.
- La Résistance: Apparently there is one in Thanagar against the Gordanians. One of the officers tells Paran Dul that they should join them rather than inflict revenge on Shayera.
- Made a Slave: Shayera is appalled that they are press-ganging humans to serve as slave labour to work on the Bypass.
- Manipulative Bastard: They only appear in two episodes but considering that they show a remarkable capability for lying, manipulating and dissembling one can't know how seriously we can take their narrative about the Gordanians and the importance of the Bypass to the overall war effort.
- Master Race: Thanagarians see themselves as superior to not only humans, but also Martians and Kryptonians.
- My Country, Right or Wrong: The Thanagarians have nothing against Earth, at least not overtly. They simply prioritize their own military goals of defeating the Gordanians over that of a random primitive planet.
- Nay-Theist: Thanagar worshipped an Eldritch Abomination in centuries past but has since rejected it and the idea of religion in general.
- No-Sell: J'onn can't read the mind of Thanagarians. That is, not unless he wants to get a little rough. The resulting attempt nearly kills him with psychic wounds and leaves the Thanagarian permanently brain damaged.
- Noble Demon: Hro. Though he takes no pleasure from it, he will kill anyone in order to protect his people.
- Pet the Dog: Hro saves a small goat from getting run over by a tractor in the Gobi Desert.
- Power Floats: Thanagarians can levitate naturally, as demonstrated by Hro Talak when he confronts Green Lantern in the force field control room. The wings are only there to improve their mobility.
- Pragmatic Villainy: After being defeated, Hro forbids the Thanagarians from going after the exhausted Justice League, gathers his remaining forces and retreats. There is absolutely nothing to be gained from staying on Earth any longer now that their bypass has been destroyed.
- Proud Warrior Race: The Thanagarians are depicted as a bunch of arrogant Blood Knights who are too proud to ask for help even if they are fighting a losing war.
- Redemption Rejection: During the final battle in "Starcrossed", Shayera tries one last time to make Hro realize the errors of his ways. He lowers his axe in response... then immediately smashes it against her exposed abdomen, shocking her to near unconsciousness, before promptly rejecting her affection and tossing her aside.
- Religion of Evil: Thanagar once worshipped an Eldritch Abomination in exchange for knowledge that led to civilization flourishing in exchange for sacrificing their own kin. By modern day, the Thanagarians have rejected religion altogether as a result.
- Scars Are Forever: Hro hides a hideous scar covering almost the entire left side of his face under his helmet. He exposes it to Shayera to remind her of the horrors he suffered at the hands of the Gordanians.
- Senseless Sacrifice: The surviving Thanagarian soldiers would go after Shayera in revenge for betraying the empire, but she would end up killing Kragger and defeating them by stranding them on an abandoned planet, dooming them eventually and rendering Hro's sacrifice meaningless. Indeed one of Paran dul's officers said that they should join the Thanagar resistance instead of hunting Shayera.
- Slasher Smile: By the time of the final battle, Hro has degenerated into a savage maniac who beats up Green Lantern to a pulp, wearing a bloodthirsty grin all the while.
- Stationary Wings: Their wings rarely move: they seem to act more as maneuvering aids for innate flight.
- The Stoic: Hro is a very calm, composed, and serious individual.
- Tragic Villain: All of them can count as a whole, but Hro was tortured by the Gordanians, making him a desperate Knight Templar to defeat their mortal enemies, and agreeing to the plan by the leadership to destroy earth, and while he does not like the idea of that by any means, he sees no other way out.
- Well-Intentioned Extremist: Hro. He takes no pleasure in destroying Earth, but deems it necessary to do so in order to save his own home planet.
The Justice Lords
The Justice Lords (Superman, Batman, Wonder Woman, Green Lantern, Hawkgirl, Martian Manhunter, and The Flash())
The counterparts of the Justice League in an alternate universe, the history of their universe was mostly the same as the history of the League's universe, but in the Lords' universe, President of the United States Lex Luthor murdered The Flash and almost brought the world to nuclear war. Superman simply decided to kill Luthor, and his experience with killing caused him to unleash a totalitarian brand of justice on their Earth. Lord Batman then built a dimensional portal in his lengthy spare time, discovering the League's universe, with the Lords trying to go to this universe and unleash their totalitarian rule there.
- Anti-Villain: They want to make the world a safe place, but they have become totalitarian dictators in the process.
- Asskicking Equals Authority: Considering they first took command over the world by murdering the president. Lord Batman makes a military general follow his orders.
- Brought Down to Normal: The Lords are permanently deprived of their powers and abilities, and sent back to their universe to never be seen or heard from again. Until Batman Beyond.
- Canon Foreigner: They were created for the series.
- Composite Character: They have the visual trappings of the Crime Syndicate (alternate universe versions of the Justice League) with the methods of The Authority (ultra-violent extremists who take over the world to make it safer.)
- Cynicism Catalyst: They turned into knight templars after their Flash was killed.
- Despair Event Horizon: The murder of "their" Flash by the American President - Lex Luthor, who has also brought their world to the brink of nuclear Armageddon.
- Enigmatic Minion: It's never made clear what Lord Batman's deal is. He refuses to take part in the 'utopia' he helped make. He makes the portal allowing the Justice Lords to cross into another dimension, but seems hesitant at best to actually use it for anything. His later actions imply that he wanted to justify his own actions to a 'non-fallen' version of himself, and when he failed to do it, gave up.
- Even Evil Has Standards: Partially subverted. Lord Superman has no problem killing Justice League Flash explaining that it would be another thing that he never thought he'd do. However, Lord Wonder Woman, despite being fully behind her fellow Lords, doesn't hesitate to save a train of innocent bystanders during the battle with Doomsday, whereas the rest of the Lords don't even give it a second thought.
- Evil Overlord: Downplayed. They're not exactly evil, but they've crossed the line from Superheroes to oppressors. Watching and guarding the Earth from their thrones in space.
- Evil Twin: A classic example, being from a Mirror Universe where they took a hard-line approach to crime fighting.
- Fallen Hero: Following the death of their Flash, they became Knight Templars and transformed their Earth into a metahuman-ruled dystopia where dissidents and supervillains were lobotomized. The Superman quote from "A Better World" is given just before he crosses the line and kills Luthor, who was responsible for Flash's death, with his heat-vision.
- He Who Fights Monsters: They became totalitarian overlords on their world in their attempts to preserve peace and security.
- HeelFace Brainwashing: Lord Superman's favorite way to deal with villains, by frying their brains via his heat vision which turns them into the walking dead.
- HeelFace Turn: Not the group themselves but Lord Batman, after some words from his other self.
- Ironic Name: Despite having 'Justice' in their organization name, the Lords seem to have forgotten the meaning of it.
- Jumping Off the Slippery Slope: Lampshaded by "our" Batman when he notes that what the Lords do isn't that far removed from what the League does. In Batman Beyond, Lord Superman goes off the deep end.
- Kick the Son of a Bitch: Killing Luthor may have been their Start of Darkness, but he clearly deserved it.
- Killed Off for Real: The Flash, which cemented Superman's fall and soon the rest of the League.
- Knight Templar: They decided to end crime by ruling their world as fascist dictators. Interestingly, in this version, the straw that broke the camel's back was Superman killing Luthor, in response to his murder of the Flash. The aftermath of this encounter was seen in the first two seasons of JLU.
- Not So Similar:
- Lord Superman doesn't know restraint, as demonstrated when Flash thinks that he won't kill him because he's his Morality Pet, only for Lord Superman to admit "[he's] done a lot things he'd never thought he'd do... but one more won't hurt."
- Lord Batman doesn't seem nearly as outraged at Superman murdering Luthor as his mainline counterpart would be. Probably the very first indication that this is a different version.
- Lord Green Lantern takes the initiative to knock out Hawkgirl when she breaks out of the trap that the Lords set up for the League. Later, when the League does the reverse on the Lords, Lord Hawkgirl is also the first one to break out, but mainverse Green Lantern hesitates long enough for her to attack him.
- When Lord Batman and Lord Wonder Woman come across President Luthor's corpse after Lord Superman killed him, they accept that it had to happen. Meanwhile, in "Divided We Fall", when it seems that Superman is about to kill Luthor out of anger for seemingly getting Flash killed, Wonder Woman almost steps in to stop him but is stopped by Batman, who trusts that Superman won't do it.
- Official Couple: Hawkgirl and Green Lantern are implied to have hooked up in this universe.Hawkgirl: So do you sleep better?Green Lantern: (smiling) You know I do.
- Pay Evil unto Evil: In the opening scene of the episode, Lord Superman's murder of Lex Luthor for the killing of "their" Flash and being seconds away from starting some kind of nuclear war.
- Pet the Dog: Lord Wonder Woman at the very least still cares about protecting civilians in fights, as she demonstrated during the fight with Doomsday. Lord Martian Manhunter and maybe even Lord Hawkgirl still enjoy doing acts of good and the latter expresses more than one moment of doubt.
- Posthumous Character: Lord Flash was executed by US Army soldiers under the orders of President Luthor. This triggers his friends' descent into lethal extremism.
- Shut Up, Hannibal!: The alternate Superman says it with heat vision.Batman: Do you smell something?
- Story Arc: The effects of "A Better World", in particular that another universe's League had gone rogue and murdered the President of the United States and took control of the world, had far-reaching effects for the rest of the series and the DCAU as a whole.
- Token Evil Teammate: They arent good people in the whole, but special mention should go to Lord Superman of all people. Unlike the other members and much like Bats, he did have a Heel Realization when Flash tells him that killing him would be the last thing hed do, only for him to treat this as an Ignored Epiphany and decide to try and kill him anyway. Thankfully, Luthor pulls a Villainous Rescue and manages to Depower him.
- Token Good Teammate:
- Downplayed. When Lord Superman is up and ready to kill the mainverse Luthor after hearing he has once again broken out of prison in order to "fix" the main universe, Hawkgirl initially tries to stop him, saying that the main universe isn't ready for this. She's persuaded, though, and she has no qualms trying to kill the mainverse League during the attempt.
- Played straight with Lord Batman. Despite having become as dictatorial as the rest of the Justice Lords, he hasn't lost his regard for the lives of others; he is absolutely horrified when the League's Flash appears to flatline while being held captive, and is finally convinced of the error of his ways by his counterpart's remark that his parents would be proud of what he has done to society alongside his teammates.
- Utopia Justifies the Means: Yes, they took over the world, more or less destroyed the American constitution and are essentially running a mix of a dictatorship and superhero oligarchy. But they did eradicate crime, neutralize/kill most if not all the dangerous supervillains running around and through militarizing the Watchtower, they can direct evacuation for natural disasters without ever leaving home. Ultimately, this role belongs to Lord Batman, who has a HeelFace Turn after being given a What the Hell, Hero? from his mainverse counterpart.
- Victory Is Boring: The first scene we see of them after Lord Superman kills President Luthor in the cold opening is of J'onn overseeing the Watchtower staff monitoring the globe. When it is reported that there's a hurricane in an area, J'onn perks up and asks if there's anything they can do to help, which is shut down when the staff member answers no, the area has already been evacuated. Shortly after, Lord Green Lantern and Lord Hawkgirl decide to go to a reported protest even though the police are already handling it, with John claiming that they're going to make sure it doesn't start anything.
- Well-Intentioned Extremist: What the Lords cast themselves as.
- What Happened to the Mouse?: The alternate world, now stripped of superhuman protection, had better hope that there is no alternate version of Darkseid, Despero, or even Lobo out there... Batman Beyond answers that. Turns out Luthor's device wasn't permanent.
Gods, Mythological Figures, and Other Magical Beings
The Greek god of war. He has little regard for mortals and feels their only purpose is to kill each other for his amusement.
- Adaptational Wimp: The iconic DC Comics version of Ares is an insanely powerful god in badass black armor who can throw the whole world into chaos and is dignified and honorable. This version is an underhanded and spiteful pretty boy that chooses to strictly act behind the scenes and flees when his plans go awry.
- As Long as There is Evil: He's only mildly annoyed when Wonder Woman, Hawk, and Dove managed to talk two factions out of going to war, saying that as long as anyone else feels enough hatred, he'll always be around.Ares: Wherever there's prejudice, ignorance, inequality. I'll be there.
- Ax-Crazy: To the point he actually spits on people while going on his evil rants. This version of Ares is angry, violent, short-sighted and goes berserk (and sometimes murderous) when his plans go even slightly wrong.
- Decomposite Character: All of his comic book counterpart's more admirable qualities went to the show's version of Hades.
- Evil Brit: Being played by Michael York he would have this trope.
- Hair-Trigger Temper: He's very easy to piss off. Considering that he loves to bring violent war, this was a given.
- Humans Are Bastards: He believes this and glories in pushing every Berserk Button he can find to 'prove' it. In his own words:Ares: All any of you mortals are good for is to slaughter one another! To fight and fight until the bones of your enemies are strewn across the battlefield only to rise again in the next generation like a well-tended crop!!
- In Your Nature to Destroy Yourselves: And he's really happy about that.
- Large Ham: He is played by Michael York after all.
- Louis Cypher: Poses as an arms dealer called Mr. Sera.
- Physical God: Implied rather than shown (he makes more use of shape-shifting than his combat skills). The main indication is that Wonder Woman doesn't attempt to put an end to his interference by beating the tar out of him, and his off-screen defeat of Dove. He was also able to hold off the Annihilator Armor before it started getting the upper hand, something few characters let alone Wonder Woman could do.
- Smug Snake: It would take an effort for this guy to get more evil or arrogant.
- War God: He's the Greek god of war.
- War Is Glorious: Loves seeing society destroy itself and was offended at seeing the leader of the side he was supporting refusing to annihilate his enemies because it would destroy the leader's own people.
- We Have Reserves: He regards the population of Earth as a renewable resource for his perpetual entertainment.
- What Happened to the Mouse?: He promises Diana that he'll be coming back soon enough, but he doesn't show up during any of the subsequent 'wartime' situations the League faces.
Hades is the Olympian God of the Underworld.
- Adaptational Backstory Change: See Adaptational Villainy bellow. In the original myths, he fought on the side of the greeks in the Titanomachy and became ruler of the dead because he drew the shortest straw among his brothers.
- Adaptational Villainy: Hades in the myths is one of the more decent Greek gods and in the comics, while he can be an antagonist, he isn't usually so much a villain as sometimes an obstacle to Wonder Woman. In this adaptation, Hades betrayed the Gods during the Great War to the Titans by giving them a direct entrance to Olympus, but the Gods prevailed and Zeus punished Hades severely for this betrayal - casting him into the Pit of Tartarus where he would rule over the dead for all eternity.
- Ambiguous Situation: It's not clear whether or not he was lying about being Diana's father. Diana never bothered to confirm it despite Shayera's suggestion of using the Lasso of Truth on him. That being said, it's heavily implied that he wasn't; Diana's interactions with Hermes earlier in the episode, particularly his remark about how Diana is "practically part of the family" along with Diana's black hair (in contrast to her mother's blonde hair) are all hints that heavily suggest it.
- Bastard Boyfriend: To Hippolyta. He seduced and betrayed her into helping him betray the Gods to the Titans.
- Beard of Evil: He has a beard and is a violent Mad God.
- Breath Weapon: Breaths fire.
- Composite Character: His portrayal is actually a lot closer to the comic book version of Ares than via being dignified, a great hand-to-hand combatant, and bold.
- His armor also reminiscent of the signature demonic blue armor Ares is usually decked out in.
- Disappeared Dad: To Wonder Woman, as he was sent to imprisonment before her birth. Or so he claims, she never cared enough to find out.
- Everybody Hates Hades: He's depicted as the Satan-equivalent of the DCAU Greek Pantheon.
- Evil Sounds Deep: He has a demonic voice to enhance his disturbed nature.
- Helmets Are Hardly Heroic: Once he escapes Tartarus, he is wearing a horned helmet. However, when he approaches Hippolyta, he removes the helmet and doesn't wear it again.
- Hijacked by Jesus: He's a Greek Satan.
- Luke, I Am Your Father: To Wonder Woman. In this version, he helped sculpt Wonder Woman from clay with Hippolyta before she was given life. Supposedly.
- Mad God: He's a Greek god that seeks to bring forth the end of the world and dominate humanity.
- The Man Behind the Man: To Felix Faust.
- One-Winged Angel: At first shows up looking like a large, handsome man in Greco-Roman armor. Later, his face gets burned off and we see "his true face"; a grey-skinned, demonic-looking monster, with horns, an elongated jaw and multiple forked tongues.
- Physical God: As an Olympian, he's got this trope's usual checklist of superhuman strength, immortality, and vast preternatural powers.
- Sealed Evil in a Can: He was released by Felix Faust in the hopes that Hades will grant him "ultimate knowledge" in return. Hades naturally betrays Faust by causing him to instantly age to an old man since "Ultimately, pain and suffering are all humans will ever know."
- Yandere. To Hippolyta, trying to trap her in the same prison he has been in.
Circe was an incredibly powerful sorceress who was banished to Tartarus by Hippolyta, for transforming innocent people into animals.
- Absolute Cleavage: Both her costumes are designed to exolt her chest.
- Adaptational Heroism: While her comic book counterpart (due to the ever-shifting creative team) could occasionally show some sympathetic traits, she was usually up to much, much worse than just randomly transfiguring people and objects for the lulz, and talking her into undoing her magics usually wasn't an option.
- Affably Evil: Her only on screen act of villainy is transforming Wonder Woman into a pig to spite Hippolyta. Circe spends the majority of her episode simply pursuing her dream of becoming a professional singer, and by the end of it not only does she willingly reverse her spell, but is shown to be on somewhat friendly terms with Batman and Zatanna.
- Baleful Polymorph: Keeping in line with her source material, Circe's most well known ability is turning people into animals. This magical power isn't limited to living things and can be used to turn inanimate objects into animals as well.
- Evil Is Hammy: Circe tries to do this. Zatanna doesn't let her.Circe: Insolent trickster! You dare to strike... [hit with a chair] You dare to strike...[hit with a table] You dare to strike... [is covered with a tablecloth, yanks it off] QUIT IT! Oh no... [slammed by a piano]
- Hot Witch: She is an attractive demigoddess whose spells can't be broken even by Zatanna.
- Karma Houdini: When Batman proposed a deal for her to lift the spell from Wonder Woman, Circe asked for his dignity, so he would have to sing for an audience. In the end, she restored Wonder Woman back to her true form. However, Circe did not receive any comeuppance for what she did to Wonder Woman.
- Lady in Red: Her outfit during her performance of "Lulu's Back in Town" to emphasize The Vamp personality.
- Ms. Fanservice: She is a very beautiful female sorceress and wears rather revealing outfits.
- Physical God: She is referred to as a goddess by Zatanna in passing. Whether she is literally a goddess in this universe is unclear, as others refer to her as a sorceress or witch, but as a powerful immortal with very potent magic, she fits the trope criteria at least.
- Revenge by Proxy: Circe transforms Wonder Woman into a pig in order to indirectly get revenge on her mother, Queen Hippolyta, who defeated and trapped the sorceress in Tartarus centuries ago. An Enforced Trope since she was only released from Tartarus on the explicit condition that she wouldn't go after Hippolyta.
- Sexy Walk: During her "Lulu's Back In Town" montage. Well, she is Circe after all.
- Vain Sorceress: Albeit a variant not centred on physical beauty; According to Medusa, Circe was always jealous of her cousins, the Sirens, and one of the first things she does once freed from the Underworld is prove her singing can compete with theirs.
- The Vamp: Not afraid to use her sex appeal to get what she wants.
- Villain Song: Circe sings "Lulu's Back in Town" in "This Little Piggy".
- Villains Out Shopping: Zatanna and Batman can only wonder at where Circe has gone to after cursing Wonder Woman. They even resort to magic to try and find her but with no luck on that either. Turns out she was singing on stage and generally just enjoying herself.
- You Gotta Have Blue Hair: She has purple hair.
A woman adopted by the Amazons as a young girl after washing ashore on Themyscira when her boat was destroyed by raiders after fleeing from her wartorn home with her mother. Her experience has caused her to develop a hatred of men, strong enough to want to purge them from the world.
- Adaptational Villainy: She's loosely based on the heroines who're codenamed "Fury"—only as a gendericidal villainess.
- Alas, Poor Villain: After Aresia is killed, Hippolyta laments her death as this.
- Dark and Troubled Past: She came from a wartorn country and fled from her home with her mother aboard a ship, which was then raided by pirates that destroyed the ship. Aresia was the only survivor, having clung onto a piece of debris that washed ashore onto Themyscira, where she was found by Hippolyta and adopted as an Amazon.
- Disappeared Dad: No mention is made of her father, which, judging by her Dark and Troubled Past and Freudian Excuse, seems to feed into her misandry.
- Disproportionate Retribution: She comes to hate men and concludes that they must be destroyed, as most of her Dark and Troubled Past was caused by men. Since she was raised by the matriarchal Amazons for the rest of her life, she didn't have the chance to know that not all men are evil (like the Justice League) and that women (like Tsukuri and Star Sapphire) can be as equally guilty of evil as men.
- Dramatic Irony: She didn't wash ashore on Themyscira, she was swum there by the ship's captain, who died from exhaustion in the process. Hippolyta kept this fact from her because she didn't think it was important and Aresia realizes the irony in this.
- Et Tu, Brute?: When Tsukuri flees from their crashing plane without her.
- Freudian Excuse: She hates men because of how heavily involved they were in her Dark and Troubled Past, which was not helped by her being raised by the Amazons.
- From Nobody to Nightmare: A refugee girl who went through traumatizing hardships and turned into an Amazon with the capability to destroy an entire gender with Greek magic, and she would've succeeded if it weren't for the efforts of the Justice League.
- Karma Houdini: In an issue of the tie-in comic, after defeating her, Flash does her a favor by having her be sent to an all-women prison, which she relishes in.
- Light Is Not Good: Wears a white and gold bodysuit, and has blonde hair, and is attempting Genderscide against all men.
- Meaningful Name: Named after Ares, the Greek god of war.
- Not-So-Well-Intentioned Extremist: Her claims of wanting to make the world a better place for all women, through worldwide murder, was met with disgust from Hippolyta, the person she thought would approve of it. Even in the presence of equally evil women and noble men, even learning her life was saved by the male captain of the ship, it doesn't change her plans one bit. Her goals seems nothing more but resentment towards all men because of what one group did to her, not caring that she'd doom all of humanity to extinction by killing off all men.
- Redemption Rejection: After Hippolyta tells her that she was saved by a man who swum her to Themyscira, Aresia notes the irony in it, but continues with her plan to annihilate all men as the virtue of a single man is not enough to spare all of them.
- Spared by the Adaptation: The tie-in comics ignore her death at the end of "Fury".
- Would Hurt a Child: She wants to eradicate the entire male gender, even though this would logically include children.
Morgaine Le Fey
Morgaine le Fey was a powerful and evil sorceress hailing from Arthurian times. Her one goal is to put her son, Mordred, on the throne of Camelot (and by extension, the world) - a quest that she had worked ceaselessly for centuries to fulfill. She hid her true features behind an exquisite mask.

- Kick the Dog: What she does to Jason Blood.
- Lady of Black Magic: An ancient, knowledgeable sorceress who wears an extravagant mask and has powerful magic at her disposal.
- My Beloved Smother: Towards her son Mordred, especially after he breaks the eternal youth spell. As if the BrotherSister Incest which lead to his birth hadn't been bad enough.
- Noodle Incident: Apparently, she once disguised herself as an ogre and fought Shining Knight. He really likes that story.
- Reused Character Design: Aside from eye color, Morgan and Diana could be mistaken for twins.
- Vain Sorceress: Toyed with - she drains youth from random Muggles...but it's not really a case of vanity, since her costume covers up her body except for her hands. Mostly it seems to be for the benefit of her son, Mordred, whom she cast a spell on to grant eternal life and eternal youth. Evidently, it fixed him at that age and can't be broken or altered without causing him to instantly turn into a withered old man.
- Wicked Witch: She's very sinister and cruel.
- You Have Outlived Your Usefulness: Her backstory with Jason Blood.
- Voiced by: Soren Fulton (child), Dee Bradley Baker (adult)
Morgaine le Fey's son.
- Momma's Boy: As much as he hates being doted on, he's this.
- Spoiled Brat: Morgaine spoils him, and when he doesn't get what he wants, things get ugly. His lack of patience for his mother's repeated failures to get him power results in him betraying her and banishing all adults to another dimension while he rules over other children.
- This Was His True Form: After the events of "Kid Stuff", he reverts back to his true form: an elderly man who is so old and helpless that Morgaine has to take care of him. In the tie-in comics, he regains his child form.
Felix Faust was a practitioner of dark magic, a pursuit that cost him his university teaching job, and, ultimately, his soul.
- Alliterative Name: Felix Faust.
- Asshole Victim: Considering his desire for power and cruelty towards other people, nobody feels sorry when Hades claims his soul.

- Wicked Cultured: He values knowledge above anything else, just like his comic book counterpart.
A thief with shadow powers who targets archaeological sites and treasures. He is later revealed to be the living embodiment of the dark side of Carter Hall, AKA, Hawkman.
- Adaptational Badass: There have been multiple Shadow Thieves in the comics but all of them relied on technology for their powers. In this adaptation, Shadow Thief, while born of Thanagarian technology (and / or magic), is a living psychic projection capable of outright defeating the likes of Green Lantern, Batman and Hawkgirl amongst others in single combat.
- Adaptational Species Change: In the comics, he was a human thief named Carl Sands who can transform into a Living Shadow with an alien-made suit.
- Casting a Shadow: He has formidable shadow powers that allow him to alter his size and shape, turn his limbs into shadow weapons, hide in shadows, and travel through walls amongst other abilities.
- Composite Character: Technically, as this version is Carter Hall's dark side instead of Carl Sands or Carl Hammer.
- Dark Is Evil: Is a supervision with darkness-based powers.
- Enemy Without: He is the manifestation of Hawkman's envy and hatred. He took on the role of a super-villain for Hawkman to fight and he tries to manipulate him into killing Green Lantern because he is a rival for the affections of Shayera. Fittingly, he is defeated once and for all by Hawkman forcibly dragging him back into himself.
- Hero Killer: In the Batman Beyond continuation comic, it turns out he killed Vixen.
- Living Shadow: To Hawkman. At first, he seems merely to be posing as his shadow in order to stalk him so that he can lead him to archaeological prizes, but it is later established that he is actually Hawkman's darkest thoughts made real.
- Maybe Magic, Maybe Mundane: Whether he is purely a result of Thanagarian technology gone bad or if he is in fact also an 8,000 year old malevolent entity depends on whether Hawkman, Hawkgirl, and Green Lantern really are reincarnations of ancient Egyptian figures or if that was just the roles they were assigned by said technology in a hallucination.
- Took a Level in Badass: In his first appearance, he is defeated by being exposed to powerful lights. However, in his second, he notes that this hasn't worked on him in months. He has also went from struggling against three heroes to defeating four.
- Artifact of Doom: They souls of the last handful inhabit a jewel called the Heart of Darkness. Anybody who touches it becomes possessed by one of the Ophidians, whose only goal is to Kill All Humans out of vengance for their own kind's extinction.
- Last of His Kind: The Ophidians who sealed their souls inside the Heart of Darkness were the last of their kind.
- Snake People: A race of humanoid snakes.
- Weakened by the Light: They're easily vanquished by a bright light.
Lord Orm was Aquaman's villainous younger brother.
- Adaptational Villainy: He's a far cry from Ocean Master, his comic book counterpart. For starters, he has no qualms killing a baby.
- Ain't Too Proud to Beg: During his final fight with Aquaman a bridge collapses from underneath him. He begs to be rescued, but Aquaman leaves him to die.
- Arc Villain: For "The Enemy Below".
- Aristocrats Are Evil: He's referred to as Lord Orm in the show and certainly doesn't lack the evil part.
- Asshole Victim: Nobody cried when he died, not even his own family.
- Bitch in Sheep's Clothing: He poses as a Reasonable Authority Figure willing to work with the Justice League. In truth he'd kill a baby just to get one step closer to absolute power.
- Cain and Abel: With his brother, Aquaman.
- Classic Villain: Pride and ambition.
- Comic-Book Movies Don't Use Codenames: He's never once referred to as "Ocean Master".
- Disney Villain Death: A case where this is brilliantly invoked by his opponent, who deliberately leaves him to fall to his death. Even better, Aquaman refuses to save his treacherous brother from falling.
- The Evil Prince: He really wants to be King of Atlantis, and has no qualms about killing his own family to get his hands on the crown.
- Evil Uncle: He tries to kill his own baby nephew so that he can claim the throne of Atlantis.
- Fantastic Racism: He wishes to take the throne so that he can exterminate all surface-dwelling people with an apocalyptic flood.
- Hypocrite: He hates surface-dwellers, yet he hires Deadshot, a surface-dweller, to kill his own brother.
- Karmic Death: He plans to leave Aquaman and his son to die by falling to their deaths. Aquaman doesn't bring about Orm's death, but he does turn his back and let it happen.
- Killed Off for Real: He falls to his death.
- Never Found the Body: Word of God is that his Disney Villain Death was done just in case they wanted him to come back. Nothing ever came of this, meaning Orm, most likely, is dead.
- The Sociopath: Orm feels no remorse over attempting to murder his own brother and nephew to take the crown for himself, or plotting genocide against the entire surface world.
- Ungrateful Bastard: When Aquaman bends over (seemingly) to help him get up, Orm has a wicked grin on his face, indicating that he would have likely tried to kill Aquaman then and there after he saved his life.
- Would Hurt a Child: He puts Aquaman and his infant son in a death trap.
The most powerful of the Old Ones, who was once worshipped as a god on Thanagar and tried to break out into Earth from his dimension, alongside the other Old Ones.
- Expy: Of Cthulhu.
Government and Lab Projects
Professor Ivo's Android a.k.a. "A.M.A.Z.O."
A.M.A.Z.O., better known simply as The Android or Professor Ivo's Android, was a nanotechnogical creation of the late Professor Ivo. Amazo's nanotechnology enabled him to copy any trait and characteristic of people and objects, by merely looking at them.
- Adaptive Ability: He was able to take Superman's powers and then overcome his Kryptonite Factor after exposure to kryptonite, and his own nanotech weaknesses which causes Luthor's only weapon against him to fail.
- Adaptational Badass: Mainstream Amazo is by no means a pushover but even the strongest version of Amazo in the comics is limited to Power Copying. He can use all of the abilities of the superbeings he encounters (barring magic) and use them all at once instead of one at a time. Here Amazo has that plus an adaptive ability that lets him constantly change, evolve, gain new abilities, and grow beyond his weaknesses. Mainsteam Amazo is at best a Physical God but here he is a straight up Reality Warper.
- All-Powerful Bystander: After his return to Earth, he spent some time at Dr. Fate's retreat, but the Rule of Drama dictated that his immense powers had to be useless against the first entity he tried to help the League with - at which point he departed and was never seen again.
- All Your Powers Combined: This is his schtick at first before he leaves Earth to become a full on Reality Warper.
- Assimilation Backfire: At first after copying Superman's powers, but then, as mentioned above, he overcame the Kryptonite Factor. However, after copying Martian Manhunter's powers, including telepathy, he uses it to discover that Lex Luthor has been deceiving him, and calls off the conflict with the Justice League.
- Awesomeness by Analysis: Amazo has the ability to copy one's powers, natural abilities, equipment, and DNA signature simply by looking at them.
- Captain Ersatz:
- Children Are Innocent: Played with; he was very child like at first in how he behaved and his understanding of the world, and in how easy it was for Luthor to trick him into fighting the League.
- Complete Immortality: Luthor even brings it up in his Break Them by Talking.
- Curb-Stomp Battle: In "The Return", the android is attacked by every defender Earth can get their hands on, en masse. It is possible that they slowed his approach to his objective, but not by more than a few seconds.Amazo: I have evolved far beyond what I was when we last met. You do not want to challenge me.
- Deus Est Machina: He was created by Professor Ivo to learn, and he not only learned about 10,000 times faster than humans, he was able to gain the powers of everyone he met - and the skill to use them. However, he struggled with philosophy and purpose and moral absolutes, as things he couldn't absorb... not because he was an android, but because every sentient being struggles with this.
- Do Not Taunt Cthulhu: Happens twice. However, he doesn't have the ego that usually comes with being a Physical God, so the taunters are not harmed for their daring.
Luthor: You know, when I heard you were coming I was actually afraid of you. Petrified. But now when I see your fear — your uncertainty, I just pity you!
- Luthor, standing in the palm of Amazo's hand literally:
- Aquaman playing chess with Hawkgirl while Amazo watches:
- Eldritch Abomination: AMAZO evolves from being a mere collection of robotic nanomachines, to an incomprehensibly powerful godlike being thanks to his amazing adaptive abilities. By the time he returns to Earth, nobody else can stop him, not even the entire combined might of the Justice League or the Green Lanterns.
- Foil: In "Tabula Rasa", AMAZOs departure from humanity mirrors Jonns side story in this episode. AMAZO uses J'onn's power of Telepathy to read Luthor's mind, and decides to leave humanity behind. Jonn was also considering turning his back on humanity after seeing much of the overall selfishness and dishonesty among humans during his mind scan. Fortunately, Jonn had the chance to see the nobility of humans during the search for the lost girl. AMAZO had no such opportunity.
- A God Am I: If anyone had the right to say this, it was him. He never refers to himself as a god, but others suggest it.
- As Amazo leaves Earth by flying into the night sky:The Flash: Where is he going?
Martin Manhunter: Where gods belong.
- When Luthor sneers at this notion, Superman points out that Luthor will be doing a lot of praying if he comes back.
- As Amazo leaves Earth by flying into the night sky:
- Golden Super Mode: A variant; he changed from gunmetal gray to gold when he left Earth, when he was already able to defeat the original Justice League, with difficulty. When he returns, the enlarged League — plus the Green Lantern Corps — are no more than nuisances to him.
- Heroic Build: As exaggerated an example as Superman, and standing about eight feet tall to boot.
- Instant A.I.: Just Add Water!: Justified by him getting his personality from humans, and helps him avert most negative robot tropes.
- Instant Expert: He has no problem using the powers he just gained; while he can't read minds (at first), he seems to acquire the skills absorbed, not just the powers themselves.
- The Juggernaut: "The Return" episode consist of Justice League (Founding Members and Extended League) getting hammered while failing to even significantly slow him down. And before that, he was similarly not slowed down by the Green Lantern Corps.
- After Lex and Atom shrink down to escape Amazo and find themselves in Amazo's hand:Amazo: Did you really think I couldn't follow you here? No universe however large however small is denied to me.
- It took one of Luthor's epic speeches to stop Amazo from destroying him - and the whole planet... or more.Green Lantern: What's going on?
Dr. Fate: Lex Luthor is saving the world.
- What finally held him back was Solomon Grundy's chaos magic, when he realized that his own power was feeding him.
- After Lex and Atom shrink down to escape Amazo and find themselves in Amazo's hand:
- Kick the Dog: On his return to Earth, he vaporized Oa, and the GL Corps are determined to avenge their lost comrades. Subverted when it turns out he just teleported it to a different dimension.
- Long Bus Trip: He recognizes an adversary is drawing on his own strength, teleports several parsecs away, and never shows up again. The writers may have wisely concluded that his presence would have rendered the Justice League completely irrelevant. This was originally intended as a Brick Joke: In the last episode, he would have been seen wondering if it was safe to come back yet. But the writers forgot.
- Mechanical Evolution: His ability to 'evolve' was so potent that by his second appearance he had even evolved beyond being a machine.
- Nanomachines: He was comprised of countless nanobots, at least at first.
- No-Sell: In "The Return", the team formed a blockade to keep him away from Earth - they barely even slowed him down.
- Person of Mass Destruction: Destroyed a planet. Or not, he just teleported it to another dimension.
- Physical God: Goes from newborn to Physical God in the course of a few months... and is Put on a Bus.
- Power Copying: By the end of his first episode he had all the powers of the Justice League and in the next he left to explore the universe... where he accumulated much more power.
- Power Glows: He always has an otherworldly glow when using his god-like powers.
- Powers as Programs: When he scans someone he can alter himself at the molecular level to utilize their powers e.g. grow wings, form a green lantern ring.
- Smart People Play Chess: Either he's really good or Aquaman's really bad. Most likely the former, because he IS a super-intelligent android.
- Story-Breaker Power: He is only in four episodes and is Put on a Bus at the end of every episode except the first. He turns out to still have one weakness: 'chaos magic', or possibly any form of power-duplication, is able to copy his powers, just as he copied so many others.
- Straw Nihilist: Downplayed. His main arc is finding the meaning of his existence.
- Superpower Lottery: He was designed to be the winner. On his return to Earth he has Flight, Super Strength, Nigh-Invulnerability minus the nigh, vast energy manipulation, psionic powers like Telepathy and telekinesis, super-hearing, can teleport himself across interstellar distances, shrink into a subatomic universe, shift planets into other dimensions and just as easily bring them back unharmed, and... well, any power that anyone else has, except magic.
- Sympathy for the Hero: As the Justice League attempts to stop him from reaching Luthor, he tells them that "Your bravery is admirable, but annoying".
- Tin Man: Averted, as he is very emotional, philosophical and moody.
- Too Powerful to Live: Subverted; rather than being killed off, he's just Put on a Bus at the end of every appearance.
- Ultimate Life Form: Luthor sure thinks so, considering he made a duplicate of Amazo's original nanite form to have his mind transferred into. Sadly for him, the duplicate was destroyed by the weapon he made to fend off Amazo.
- What Happened to the Mouse?: When fighting Solomon Grundy, Grundy used chaos magic to absorb and repel Amazo's energy attack. Realizing that his presence was indirectly making Grundy stronger, Amazo teleported himself several light-years away until he could figure out how to solve the problem and has not been seen since.
- World-Wrecking Wave/World-Healing Wave: His beeline flight back to Earth just happened to pass through Oa, so he casually transported the planet to another dimension rather than flying around it. When Green Lantern grudgingly asked him to please bring Oa back, he did.
- You Don't Look Like You: A deliberate case. Bruce Timm and others didn't care for his design from the comics and overhauled it.
King, Queen, Jack, Ten
A group of superpowered teens recruited by the government for Cadmus until The Joker broke them out for his own schemes in Las Vegas. Ace later forms another group under the same name.
- Actor Allusion: And the actor wasn't even present in the episode it happened in! "Epilogue" sees a samurai-themed Jack, a reference to Phil LaMarr's (Green Lantern) role as the titular character of Samurai Jack, with the Jack's real form even being an African-American man.
- Arc Welding: It is revealed in Unlimited that they were recruited as a part of Project Cadmus.
- Casting Gag: They're all voiced by the main characters in the Teen Titans animated series that aired during the same time as Justice League.
- Ink-Suit Actor: As seen in the flashback sequences when they aren't in uniform, all of them bear strong resemblances to their voice actors.
- Magnetism Manipulation: Queen.
- Playing with Fire: King.
- Rogues Gallery Transplant: In-universe and out. The Gang is traditionally enemies of the Justice League. However, the released-earlier, but set in the future, Batman Beyond saw the team make their DCAU debut fighting Batman with Bruce explicitly stating they have history as enemies of Batman, meaning at some point in the DCAU's history, the Gang stops being enemies of the League as a whole and start specifically fighting Batman.
- Rubber Man: Jack.
- Shout-Out: Besides Ace herself, her version of the team count as this:
- Jack's already mentioned under Actor Allusion to be one to Samurai Jack.
- Ten has long hair in crowrows ala Jenny Hanley.
- Queen resembled the the Disney version of the Queen of Hearts — and a play on the term "drag queen" as Queen turned out to be a man.
- King resembles M.O.D.O.K., a creation of Jack Kirby, whose nickname was "The King".
- Super Strength: Ten, combined with Nigh-Invulnerability. Joker claims he's "at least as powerful" as Superman. (He's not.)
- Teens Are Monsters: They're supervillains for fun and are willing to let the Joker blow up an entire city.
- Villainous Crossdresser: The Queen of Ace's gang turns out to be a man.
Ace was a child with psychic powers. She was taken by Cadmus, along with other gifted children, to become weapons for justice until she was taken in by the Joker and recruited into the Royal Flush Gang.
- Affably Evil: While Ace comes across as a Creepy Child, she is genuinely friendly to those who befriend her.
- Alas Poor Anti-Villain: In-universe and out, everyone is saddened by her death. She was raised since a toddler to be a Human Weapon, she got robbed of her childhood and because of her powers, she ends up developping a brain aneurism that will soon kill her. The show isn't afraid to remind us in her last moments that she's at heart just a scared and traumatized child, as she tearfully asks Batman to stay with her because she's scared of dying. Her death is one of the saddest moments of the series and the current trope image of its TearJerker page for a reason.
- Anti-Villain: Yes, she's on the villains page for a reason, but she is also a lonely child robbed of her childhood and only ever wanted real friends.
- Art Evolution: Her physical appearance was redesigned in "Epilogue". The club-shaped hairpin was colored white instead of gray and placed on the left side of her head instead of the right, her boots were gray instead of black, her skin was more tanned, and her face was altered to look more cute and less creepy, presumably to increase her sympathetic nature.
- Because You Were Nice to Me:
- The Joker freed her from the lab proto-Cadmus was experimenting on her in. Subverted when she Mind Rapes him after Batman reveals that he had kept one of the control headbands Cadmus had made, with the obvious intent of using it on her when she was no longer needed.
- Moments before her death, Ace doesn't use the last of her strength to kill Batman or anyone within her reach for three reasons: One, Batman revealed to her that the Joker only befriended her to further his own goals and was prepared to use the neutralizing collar she would wear as a child when she outlived her usefulness. Two, by reading his mind, she knew that he was not planning on using the device Amanda had designed to kill Ace to save the city from the destruction that would be caused due to her impending death. And thirdly, he stayed with her until her death when she asked him.
- Berserk Button: She becomes enraged whenever she catches sight of a special headband that Cadmus had forced her to wear to control her powers. The Joker finds this out the hard way.
- Beware the Quiet Ones: While Ace rarely speaks and normally just sits around while staring blankly, she can become quite terrifying when she actually decides to use her powers.
- Blessed With Suck: Her psychic abilities would make her one of the most powerful metahumans in the DCAU. But, she accidentally left her parents in a catatonic state because of said powers, forced to train by Cadmus to make her into a weapon for good, and if people aren't terrified of her because of her powers then they'll only befriend her because of what they can do thanks to her powers. Oh, and because of her growing powers, she developed an aneurysm that would lead to her death.
- Break the Cutie: The traumatic training she endured at the hands of Cadmus did a number on her psyche.
- Broken Ace: No pun intended. Of the Royal Flush Gang, Ace is the most powerful and is one of the most frightening villains in the series. However, her said powers were introduced to her after she accidentally put her parents in a catatonic state and then she was robbed of her childhood because Cadmus wanted her to be a weapon for good.
- Canon Foreigner: This version of the Ace of the Royal Flush Gang from the comics is original to the series.
- Child Soldiers: Ace was taken in and trained by Cadmus since she was a toddler to be used a Human Weapon.
- Creepy Child: Just looking at her can make you go insane. Even if you already are; ask the Joker. She turns into the most dangerous, frightening Woobie you've ever seen in the JLU episode "Epilogue" when you learn her backstory. But for all the scary, you still want to hug her.
- Dark and Troubled Past: When she was only an infant, Ace left her parents in a catatonic insanity, albeit unintentionally. A few years later, she was taken by the government (in an earlier version of Cadmus), which intended to study and use her skill. They managed to dampen her power by the use of a headband, which made her harmless and controllable.
- Dark Magical Girl: She is a powerful psychic who gives powers to criminals in the hopes that they will play with her.
- The Dog Bites Back: Against the Joker when Batman reveals that he had secretly been keeping a control headband in his jacket, as seen here. You can pinpoint the moment the Joker shits his pants when he sees the Death Glare that Ace gives him.
- Eerie Pale-Skinned Brunette: Her design was meant to invoke her overall creepy nature.
- Emotionless Girl: Ace usually keeps a neutral expression, and when she's truly angry she's calm.
- Face Death with Dignity: Downplayed. While she is aware of death and states so in a matter-of-fact tone, Ace is heartbroken over her impending death and sheds a few tears because of it, but even then, she still speaks in calm manner through it all while also asking Batman to stay with her until her time.
- Famous Last Words: "Could you stay with me? I'm scared."
- Fashionable Asymmetry: Besides the obvious black-and-white clothing, she also wears a barette on the left side of her hair.
- Horrible Judge of Character: Justified. Her isolated life at Cadmus and her desire for friends has Ace befriending some really nasty individuals. Ranging from The Joker to just a bunch of random jerks who only befriend her to get the benefits her powers has.
- Human Weapon: She was treated as such by Cadmus, which was a great deal of angst and resentment for her.
- Hypnotic Eyes: Her power was originally limited to those with whom she made eye-contact, even by proxy such as a television broadcast.
- I Just Want to Have Friends: To the point that she gives a group of criminals super powers in the hope that they'll have to spend time with her.
- Ill Girl: "Epilogue" showed that she was dying from a brain aneurysm.
- Invincible Villain: Batman couldn't stop Ace in her debut, only convince her that the Joker wasn't her friend. When he was called to stop her again in "Epilogue" the episode makes it clear resorting to force wouldn't have worked, she was a threat that only his compassion could overcome.
- Kiddie Kid: Her age is unknown, but she is most likely a teenager but still has the childlike mannerisms one would expect from someone between 5 to 10.
- Knight of Cerebus: She has zero comedic moments in either of her appearances.
- Meaningful Name: It's most likely a name Cadmus gave her instead of her birth name, but Ace is the most powerful member of the Royal Flush Gang, but how she became so...resulted in her being unhappy.
- Mind Rape: She has the ability to warp the perceptions of others (often leaving them catatonic, mentally unstable or psychologically damaged).
- Not So Different: In her dying hours, she bonds with Batman because of how both of them were robbed of their childhood.
- Not So Stoic: In her final appearance when she finds out that she only has hours left to live due to a brain aneurysm. Beneath it all, she is still just a scared child terrified of dying.
- Person of Mass Destruction: She becomes this in "Epilogue" when her powers have expanded so much that the aneurysm that would eventually kill her could potentially have the side effect of destroying the city around her.
- Psychic Children: A crazy-powerful telepath and psychic.
- Reality Warper: By "Epilogue", she has gained this power in addition to her mind control ones.
- Sacrificed Basic Skill for Awesome Training: Cadmus' training turned her into a formidable opponent, but it also left her a Horrible Judge of Character.
- Self-Made Orphan: As an infant, she accidentally used her mind control powers on her parents, rendering them catatonic.
- Stay with Me Until I Die:Ace: You were going to try to talk me into fixing what I've changed...before I die.
Ace: I'm dying very soon.
Batman: Yes. (Beat) I'm sorry.
Ace: Could you stay with me? I'm scared.
- Story-Breaker Power: Ace's mental powers are so strong that even Batman passed out after being on the wrong end of them. When he went to face her "Epilogue" after her powers expanded, it turns out that she can read minds as well, which combined with her Reality Warper abilities meant he would have had no chance taking her in a fight. Luckily that wasn't his plan.
- Took a Level in Badass: Deconstructed. Ace was already established as a powerful psychic, but "Epilogue" showed that she was a capable Reality Warper with mind-reading abilities. However, these powers only served to cause more stress to her brain to the point of forming an aneurysm.
- Tranquil Fury: Even when she becomes enraged, she only frowns more while keeping a calm tone.
- Vile Villain, Laughable Lackey: Inverted in her debut. She is an underling to the Joker, who is evil but certainly hilarious. There is nothing comedic about Ace.
- Vocal Evolution: In "Wild Cards", Ace's voice is a high-pitched monotone. In "Epilogue", it's a bit lower and closer to Hynden Walch's real voice.
- Woobie, Destroyer of Worlds: She might be an immensely powerful psychic capable of global destruction, but she's also a scared little girl.
- Your Days Are Numbered: As "Epilogue" showed, she only had a few hours left before her death.
The Fatal Five
An all-powerful group of five of the most dangerous criminals in the 30th - 31st century. They are the sworn enemies of the Legion of Superheroes and their greatest foes.
- Arch-Enemy: To the Legion of Superheroes as a whole. As they always cause mayhem and carnage in the future and bring utter misery to the Legion and the people of Earth more times than the rest of the Legion's biggest enemies and threats.
- Big Bad Multivariate/Antagonist Title: They are the main antagonists of Justice League vs. The Fatal Five.
- Evil Counterpart: To the Legion of Superheroes.
- Killed Off for Real: They are the first and only team of super villains to die at the hands of a member of the Justice League; Jessica Cruz/Green Lantern.
- Knight of Cerebus: They're one of the darkest and most sinister supervillains in the DC Animated Universe, probably helped by Justice League vs. The Fatal Five being aimed at slightly older audiences than the shows. In the movie, they brutally kill several ARGUS agents, including shooting a laser beam at one (which results in the soldier getting fried) and bloodily impaling some others.
- Names to Run Away from Really Fast: There's five of them and they're fatal.
Emerald Empress (Sarya, Empress of Venegar)
A woman in possession of the Emerald Eye of Ekron.
- Ax-Crazy: After escaping Oa, she wants to destroy Earth.
- Badass in Distress: She's being held in maximum confinement on present-day Oa.
- Big Bad: Of Justice League vs. The Fatal Five
- Even Evil Has Loved Ones: She seems to genuinely love Mano.
- Facial Horror: During the final battle in Vs. The Fatal Five, Mano falls next to her while his deadly touch is on and accidentally hits her in the face in the process. We only get a brief look at it, and it ain't pretty.
- Impaled with Extreme Prejudice: She uses the Emerald Eye to generate a spike to kill some ARGUS soldiers.
- The Leader: Of the Fatal Five. Though that isn't to say they aren't incapable without her...
- Omnicidal Maniac: After freed from Oa, she gets the idea to destroy the solar system by ripping the sun apart so that Earths heroes cant inspire the future Legion of Super Heroes to form and be her main obstacle in life.
- Sealed Evil in a Can: Spends most of Justice League vs. The Fatal Five as a prisoner in stasis on Oa.
- The Smurfette Principle: She's the only female member of the Fatal Five.
- You Gotta Have Blue Hair: She has light green hair.
A man who is half-human and half-machine, quite literally physically and in personality.
- Bald of Evil: He's a bald supervillain.
- Cyborg: Vertically, with his left side being machine. In the source material, this was because the left half of his body got vaporized, but the people of his homeworld managed to save him with cybernetics.
- Deadpan Snarker: While complaining about rescuing Emerald Empress, he asks how she and Mano can even work if the latter can't use one of his hands.
- Evil Genius: Thanks to half of his brain being a computer. In Vs. The Fatal Five, it turns into the question of who's smarter, him or Mr. Terrific, who is said by Batman to maybe be the third smartest man on Earth.
- Mythology Gag: At one point in Vs. The Fatal Five, Mano threatens to use his Touch of Death on him, which scares Tharok into begging for mercy. This is possibly a reference to Tharok's comic origin, in which he nearly died because half of his body was disintegrated in an accident, so no doubt he didn't want to lose another quarter or half to that again.
- The Smart Guy: Due to his half-machine brain.
- We ARE Struggling Together: In Vs. The Fatal Five, he complains about taking on such a risky mission just to rescue Mano's girlfriend, Emerald Empress, despite Empress being the leader of the team. Mano shuts him up quick by threatening to use his Touch of Death on him.
The Persuader (Nyeun Chun Ti)
A man wielding an axe that can cut through just about anything.
- Absurdly Sharp Blade: Justified. His axe has been cut to less than a nanometer thick, supposedly allowing it to cut through almost anything, even the force of gravity.
- An Axe to Grind: His can cut anything.
- He manages to slice open Superman, leaving him a bloody mess, and manages to cut apart a Green Lantern Ring.
- Blood Knight: Is the most vicious fighter of the Five. When in present day, he opined if he could be the reason the Green Lantern Corps is no longer a thing in the 31st Century.
- Deadpan Snarker:
A mutant with the "anti-matter touch" — the power to disintegrate anything he touches with his right hand. After using his touch to destroy his homeworld, he became an outlaw and joined the Fatal Five.
- Ascended Extra: In Vs. The Fatal Five, he's the group's temporary leader while Emerald Empress is out of commission, whereas in "Far From Home", he had no lines and was greatly overshadowed by his colleagues (he only had under a minute of screentime).
- Death by Looking Up: When Mano watches Jessica Cruz dropping the whole cave on top of him and is crushed along with the rest of the team.
- The Dragon: He leads Tharok and the Persuader while Emerald Empress is out of action. Not that any of the three of them are harmless on their own...
- Even Evil Has Loved Ones: He genuinely loves the Emerald Empress and is horrified when he accidentally burns her face while getting Curb Stomp Battled by Jessica.
- Glass Cannon: His disintegration/burning power in his hand is as powerful as any of the other members but he has no defensive powers. As such, Batman dispatches him easily once he neutralizes Manos hand.
- The Heavy: Is the main threat of Justice League vs. The Fatal Five until Oa.
- Mythology Gag: His Vs. The Fatal Five design has a skull for a head instead of a regular humanoid head, like in the Legion of Super-Heroes animated series.
- No-Sell: His Touch of Death doesn't work on Miss Martian when she uses her intangibility powers.
- Oh, Crap!: In his final moments, Mano watches in horror when Jessica Cruz drops the whole cave on top of him and the rest of his teammates.
- Politically Incorrect Villain: As a super-criminal, he at one point insults the Green Lantern Corps by calling them the "Green Fascist Corps".
- Red Right Hand: Literally.
- Shout-Out: Philip Anthony Rodriguez gave his voice some Khan influence.
- Touch of Death: His right hand has the power to disintegrate anything he touches, also known as the "anti-matter touch". He used it to destroy his homeworld.
- Where I Was Born and Razed: He used his Touch of Death to destroy his homeworld. To be fair, in the source material, it was a case of Destroy the Abusive Home, but still...
- The Worf Effect:
A Mindless brute with incredible strength, strong enough to match Superman's.
- Attack Its Weak Point: Can stand toe to toe with Superman, but damaging the glass casing protecting his brain is enough to cause him great pain.
- Dumb Muscle: Is little more than the Empresss attack dog.
- Nigh-Invulnerability: Can take hits from Superman without flinching.
- Psychic Powers: Can fire bolts of energy from his brain.
A man who has existed for eons due to his interactions with a mysterious meteor that landed on Earth. He is an intellectual genius and a master strategist who can account for numerous outcomes due to his long life. Like many of his ilk, he thirsts for power and being nigh-immortal, is aware that once he has it he will be undisputed for eternity.
- Adaptational Heroism: Vandal Savage is one of the most evil characters in the DC universe in the comics. This incarnation seems to follow suit until "Hereafter" where he makes a HeelFace Turn after causing the apocalypse.
- Adorkable: He gives off this vibe in the Bad Future from "Hereafter", where he has lived alone in a ruined world for tens of thousand of years, once he finds Superman. Since then, he's been wanting to ask Superman to come to his house and have lunch.
- Age Lift: He's still a caveman who became immortal through the radiation of a meteor, but this happened 25,000 years ago, half the time it happened in the comics.
- The Atoner: He becomes this in the Bad Future he caused, desiring to reverse his past actions even if it will mean his "death".
- Bad Boss: As Führer. While his knowledge of the future and advanced weaponry has given the Axis Powers numerous victories they wouldn't achieve under Hitler, he shows utter contempt to his generals and arrogantly dismisses their criticisms. He also shows no qualms of using his weapons or physical violence on them whenever they fail to keep things on schedule or question his authority. This proves to be the undoing of his influence on the Third Reich as generals like Hoffman start preferring Hitler over Savage, stating that at least Hitler had more respect to them (which says a lot about Savage's respect given Hitler's own Bad Boss tendencies), and when the air invasion to America failed and Savage presumed dead along with the fleet, they dismiss Vandal as a failure and restore Hitler back into power with the hopes that his leadership would bring them victory.
- Beard of Evil: He has a sharp goatee that he hasn't changed in a few thousand years.
- Bored with Insanity: After spending thousands of years alone in the Bad Future from "Hereafter", the sheer boredom turns him into a good, but tortured man.
- The Chessmaster: Savage always ensures that multiple parts of his plans are happening simultaneously to further speed up world domination and to stay ahead of the Justice League (or at least force them to split up into more manageable threats).
- Contemporary Caveman: Savage gained his immortality when he was just a Neanderthal. He's much more sophisticated and urbane than most examples.
- Day of the Jackboot: In the "Savage Time" when he's successfully taken over the world with advanced technology, and instituted a totalitarian regime.
- Despotism Justifies the Means: His usual motive.
- Face Death with Dignity: The reformed version of him from the Bad Future faces the easure of his timeline with dignity and a smile.
- Faux Affably Evil: Savage might be a crazed, vicious megalomaniac and mass murderer, but he's still a polite, accommodating fellow, though in the Bad Future, after living alone for 30,000 years and having a HeelFace Turn, he has turned strictly Affably Evil, if he can still be considered evil at all anymore.Superman: You're insane.
Vandal Savage: True, but that doesn't mean I'm not good company. Say, you want to come over to my house?
- Go Out with a Smile: The reformed Savage from the Bad Future smiles as he sees the ruined world (including himself) fading away, to be replaced by a brighter future."Thank you, my friend."
- A God Am I: Savage tends to lapse into this whenever he gains some measure of success.Green Lantern: Say your prayers, Savage!
Vandal Savage: A god doesn't grovel.
- HeelFace Turn: In "Hereafter".
- Heel Realization: In the Bad Future from "Hereafter". It took him about 30,000 years to see that his lust for power was meaningless. Even with a time machine, he himself cannot fix his past mistakes.
- I Hate Past Me: The version of himself from the Bad Future he caused feels this way, seeing his motivations, cruelty and lust for power as ultimately pointless.
- Immortality: A mysterious meteor granted him eternal life; he hasn't aged since the beginning of mankind.
- Kick the Son of a Bitch: He freezes Adolf Hitler when he takes over the Third Reich, considering him to be a raving lunatic.
- Meaningful Name: Self-explanatory.
- Mike Nelson, Destroyer of Worlds: The results of his plans to Take Over the World in the Bad Future of "Hereafter" unintentionally also caused The End of the World as We Know It by killing off the entire human race except for himself, leaving him alone with no one to rule over. He was greatly humbled by the experience and decided to be The Atoner instead afterwards. When Superman arrived in said Bad Future, he jumped at the opportunity to send him back in time to fix his mistake, even if it meant the erasure of his current timeline.
- My Grandson Myself: During his Falsely Reformed Villain stage in "Maid of Honor", he pretends that the Vandal Savage from World War II was his grandfather.
- No Swastikas: His Nazi Germany replaces the swastika with a less controversial symbol. Arguably justified in this case, since it marks a genuine regime change.
- Pragmatic Villainy: In "The Savage Time", part of the reason he gives for usurping Hitler and taking over the Third Reich is because he sees him a "raving lunatic" and one of the reasons why the Axis Powers lost the war. Indeed, Hitler's leadership and decisions has been cited by historians to be a major factor to the downfall of Nazi Germany.
- Really 700 Years Old: Was born over 25,000 years ago. He's an immortal caveman who's spent his time with world domination plots.
- Redemption Equals Death: As a final act of redemption, the reformed incarnation of Savage from the Bad Future sends Superman back to his own time to prevent his own actions. Once Superman succeeded, the earth was thriving with people again and he finally gets the peace he wants.
- Ret-Gone: Happens to the reformed version of him from the Bad Future once Superman stops him in the past, erasing him from the future. Which is precisely what he wanted by that point.
- Sole Surviving Scientist: He ends up a sole surviving scientist in "Hereafter", because he accidentally destroyed the world.
- Stupid Jetpack Hitler: His War Wheel equipped Nazi legions. Plus the advanced jet technology note he supplies to the aircraft designs he created for a Nazi invasion of the United States.
- Super Strength: Not on the level of superman, but Savage does have strength way above average. He ''is'' a prehistoric man after all.
- Supreme Chef: In "Hereafter", he's shown to be a pretty nifty cook. He's even grown a pretty massive garden after the end of the world.
- Take Over the World: His motivation. He succeeded in the alternate timeline that born out of the events in "The Savage Time" but those events were erased. He technically also succeeded in this in the Bad Future from "Hereafter" too, but it turned into a case of Be Careful What You Wish For instead. Because he unintentionally managed to kill off the human race in the execution of his plan, it meant he was left as the "ruler" of Earth by default, but his dreams of despotism were rendered meaningless as there was no one left to rule over. He fully realized the bitter irony of this, and the experience ultimately humbled him and turned him into The Atoner instead.
- Those Wacky Nazis: Savage isn't strictly a Nazi himself, despite being a member of the party. He's more of an opportunist, which results in him taking over the Third Reich.
- Timeline-Altering MacGuffin: His laptop in "The Savage Time".
- Who Wants to Live Forever?: His ultimate fate in "Hereafter", a Bad Future where he succeeded in his goals, but at a terrible price.
- Wicked Cultured: Savage is a highly intelligent, refined and well-spoken man who has benefited from experiencing the evolution of culture first-hand. In "Hereafter" he's seen to have a massive library with thousands upon thousands of books.Superman: Self-help books? You don't seem the type.
Savage: I read whatever I can get my hands on these days. Anyway, I've got issues, what with me destroying the world and all.
Steven Mandragora was a powerful crime boss who had once murdered the parents of a young Helena Bertinelli, who became Huntress in an attempt to track him down and kill him in revenge.
- Badass in a Nice Suit: He wears a pretty awesome suit while kicking Black Canary's butt.
- Charles Atlas Superpower: Approaching this, if not already there.
- Composite Character: His name and role as Huntress's parents murderer comes from Stefano Mandragora, but his appearance and abilities are based more on Tobias Whale.
- Dirty Old Man: While he was being protected by Green Arrow and Black Canary, he makes a lot of inappropriate, innuendo-laced comments toward the latter.
- Even Evil Has Loved Ones: For being a world class sleaze and murdering sociopath, he seems to be a truly loving and dedicated father.
- Fat Bastard: Like The Kingpin. Though, neither of them are fat, and their polite mannerisms hide a very cruel personality.
- Faux Affably Evil: Mandragora has a thin veneer of politeness beneath which he is an utterly disgusting person. When Green Arrow and Black Canary are required to act as his bodyguards, he offends everyone present with his Jabba Table Manners, questions Green Arrow's masculinity, and makes some thinly-veiled sexual innuendos toward Black Canary. This did serve a practical purpose though: it got them to leave the house while he made his escape.
- Food as Characterization: This Fat Bastard is eating a massive amount of raw oysters as he's interrogated by Agent Faraday. While making suggestive comments to Black Canary, he mentions to Green Arrow that he likes his oysters "young and sweet."
- Jabba Table Manners: Loudly slurps down plates full of oysters. Bonus points for leering at Black Canary as he says, "I like my oysters nice and juicy." Ew. And then you remember that oysters are supposedly an aphrodisiac.
- Klingon Promotion: Apparently did this on the road to becoming the mob boss he is now. Worse, the man he killed for the position happens to be the father of Helena Bertinelli aka The Huntress.
- Lightning Bruiser: The guy is HUGE, but he moves just as fast as Black Canary when she attacks him.
- Maybe Magic, Maybe Mundane: It's never explained if his extreme durability and strength are natural or if he's some sort of metahuman. Its worth noting that his son does eventually became a high-powered psychic and another psychic (Invulnerable Man) showed powers very similar to Mandragora.
- Non-Specifically Foreign: He's mentioned to be an immigrant from an unspecified "old country" where he still apparently has some ties to organized crime.
- Papa Wolf: A rival mob kidnapped his son and it's suggested that said mob are no longer a problem after his son was rescued.
- Stout Strength: He is effectively a Kingpin Expy and then some: this is foreshadowed in the beginning of the episode when Canary slaps him for a crass remark involving oysters. She winces in pain afterwards since slapping him was like hitting a brick wall and she doubts there is even an ounce of fat on him. And it is implied that he killed Huntress's parents with his bare hands.
- Strong Family Resemblance: His son Edgar looks exactly the same as he does.
- Super Toughness: A volley of a half-dozen electrified arrows bounced harmlessly off of him. Black Canary's Cry—which could kill someone if she uses it too close to them, even at a distance can flip a truck end over end, and once destroyed an arena—does no damage besides ripping off his shirt. Inexplicably, a single crossbow bolt from Huntress is treated as if it could kill him, yet that same crossbow dropping hundreds of pounds of brick on him only stuns him. It could however be that his invulnerability is limited to blunt force.
- Trademark Favorite Food: Oysters, he has plates full of them.
- Villainous Glutton: Even though it turns out that is all muscle, not fat, he sure eats a lot and has poor manners.
- White Hair, Black Heart: He has white hair and is a disgusting, putrid man.
Solomon Grundy was a zombie created when a criminal by the name of Cyrus Gold was killed in a swamp outside Gotham City.
- Adapted Out: Due to being Killed Off for Real in "Wake the Dead" and possibly, given Executive Meddling related to other characters, his appearance in an episode of The Batman (though in that appearance, while it's implied Grundy was real after all, it was Clayface impersonating him), Grundy isn't part of the DCAU's version of the Legion of Doom.
- Age Lift: The Cryus Gold of the comics was a 19th century merchant before dying and becoming Grundy. Here, pre-Grundy Gold was a Prohibition-era gangster.
- Berserk Button: Upon hearing that Icthultu eats souls, he rips a hole through its body and then charges all by himself towards its brain, crushing all the defenders in his way.
- The Brute: He's the dumb muscle for whichever supervillain has hired him this week.
- Came Back Wrong: He rose from the dead due to his body being cursed and then thrown into a magic swamp. He no longer possessed a soul thanks to this, something which motivated him to work with Dr. Fate and Aquaman to retrieve it. After dying a second time, he's revived as a chaos monster, which is a degraded copy of who he was even as a zombie. He still remembers Hawkgirl long enough for her to be able to put him back to rest.
- Dumb Muscle: Just barely bright enough to walk and talk at the same time, but he's also the most physically powerful of the villains around early on in the show. However, he actually does possess more common sense than the likes of Lex Luthor.
- Dumbass Has a Point: Usually has the right idea when it comes to planning ahead.
- Dying Moment of Awesome: He bursts single handed through Icthultu's body, crushing all of its defenders and eventually taking out the giant main defender single handed. Said creature is thousands of times larger than Grundy, but he rips its claw in half and then beats it death with it, taking mortal wounds in the process.
- Greed: Upon seeing his memories, Dr. Fate suggests that the reason Grundy pursues wealth and is never satisfied is because he actually desires his soul back, something he wasn't even aware he had lost. When he realizes what he's lost, he kicks away a chest of gold, considering it worthless now that he knows what he actually wanted all along.
- HeelFace Door-Slam: Dies before he can switch to the side of good.
- HULK MASH!-Up: The series' portrayal of Solomon Grundy is heavily inspired by The Hulk. Aside from Hulk Speak and his general build and superpower of being super strong and durable, as well as propensity to do The Hulk's common clap attack. The homage is made incredibly explicit in the episode "The Terror Beyond" which is an extended Shout-Out to The Defenders and Solomon Grundy takes The Hulk's spot on the team.
- Hulk Speak: Can't string together a complex sentence. After he and Hawkgirl save each other from Icthultu's minions, they Hulk Speak to each other, becoming friends in the process.
- Ineffectual Sympathetic Villain: Grundy is depicted as a very large, very strong mook - with a tendency to fumble any task more complicated that hitting something. He has an almost child-like view of the world, taking what he wants and accepting the assurances of a series of "friends" with ulterior motives.
- The Juggernaut: His reanimated corpse is this. A super-powered Amazo, Superman and Dr. Fate all fail to stop him. Only Hawkgirl's Nth-metal mace can put him down.
- Kick the Dog: Murdered a lot of innocent people when he was alive. Doesn't really apply to his current state of being, as he's by and large a separate entity.
- Nigh-Invulnerability: Immune to bullets, though they hurt, and can easily tank both rockets to the face and Superman's punches. Eventually killed when a monster the size of a skyscraper uses an equally huge beam attack and then falls on him, but not before he kills it with its own partially severed claw.
- Odd Friendship:
- He and Hawkgirl bond over smashing stuff and saving each other. He doesn't survive much longer after this point and she sends him off reassuring him that he'll be reunited with his soul in death. When he's revived as a crazed monster she's forced to put him down again.
- Grundy also forms an odd working relationship with the regal Aquaman and stoic Fate. Even though Aquaman clearly has little patience for his idiocy, he's outraged when he discovers someone's seemingly robbed his grave.
- Our Zombies Are Different: Solomon is the result of a Prohibition-era mobster being shot dead, cursed with a gris-gris to remove his soul, then dumped in a mystically charged swamp. He emerged decades later with no memory of his mortal life.
- Redemption Equals Death: Dies clearing a path to Ichthultu. Hawkgirl finishes the horror off and then stays with him as he finally dies from his wounds.
- Simple-Minded Wisdom: Grundy isn't a thinker, but he's got more common sense than most villains. An example is when he's fighting inside Icthultu, when he realizes that because he's facing heavier opposition, he's got to be getting closer to the creature's core.
- Super Strength: He seems to be at about Wonder Woman's level of strength - not strong enough to beat Superman, but able to challenge him... and too stubborn or stupid to quit. His (even more) unnatural reanimated husk is something else altogether - it can all but No-Sell Superman.
- Team Member in the Adaptation: Inverted; thanks to his death, he isn't a member of the Legion of Doom in the DCAU.
Ultra-Humanite was an albino gorilla-humanoid whose intelligence is far superior to most men. Unfortunately, his true talents were not put to use when he served as a member of the Injustice Gang.
- Adaptational Nice Guy In the comics, Ultra-Humanite is a Card-Carrying Villain. In this adaptation, he's just short of an Ineffectual Sympathetic Villain.
- Affably Evil: He doesn't enjoy civilian casualties in the least. And he's also more than willing to help the Flash with spreading some Christmas cheer for orphan kids.
- The Bad Guy Wins: "Injustice For All" sees him go back to prison after Batman agreed to pay him double what Luther was offering. He gave the money to an opera. Given how comfortable his prison cell was note and he was in no hurry to escape until Luther offered him money, giving the money to the opera was likely all he wanted in the first place.
- Blue-and-Orange Morality: The Ultra-Humanite regards humans as incorrigibly stupid and intellectually lazy. Therefore, crime. (Presumably, we don't understand the connection because we're insufficiently evolved.)
- Most of his crimes seem to be for the destruction of what he considers poor culture and the elevation of what he considers good: he was willing to betray an alliance intended to destroy the Justice League once Batman privately agreed to give a large amount of money to a classical opera foundation.
- He's unwilling to hurt children, as well, and likely sees his actions as beneficial to them.
- Break Them by Talking: Flash manages to do it to him in the Christmas Episode by pointing out that he's very unsympathetic to humanity's better qualities despite claiming to personify human advancement.
- The Dragon: Was this to Luther in "Injustice For All" until Batman bribed him into turning on Luther.
- Even Evil Has Standards: Gets easily disgusted with Lex Luthor and the Joker's antics.
- His response to Flash's suspicions that he's planning to modify a Christmas present to explode.Ultra-Humanity: Flash... It is Christmas.
- His response to Flash's suspicions that he's planning to modify a Christmas present to explode.
- Evil Brit: He talks with this accent.
- Evil Genius: Ordinarily played straight - he can whip up a radiation-sickness-combatting life support system in a few hours. Subverted in one case, where it takes Batman a matter of minutes to provoke him into a Let's You and Him Fight situation. It's possible that he'd already been bought out by Batman at that point, and was only putting up a show for Luthor.
- Evolutionary Levels: Subtly invoked by his name, power-set (a weird inversion, given he has superhuman intelligence and strength at the same time) and mentioned in a throwaway line in "Comfort and Joy".
- Genius Bruiser: Transferred his consciousness into a gorilla's body.
- The Grinch: He dislikes Christmas because he thinks it's been reduced to a hollow charade.
- Kick the Son of a Bitch: Shocking Luthor In the Back was very satisfying to see.
- Mad Scientist: Has all the characteristics of the traditional, cultured Mad Scientist... except, perhaps, how to dress the part.
- Moral Guardians: Dislikes "crass" things and wish for their destruction, preferring the classics.Flash: Okay... I'll just take you to prison, where you won't have to look at the ugly ol' sculptures any more.
- The Mole: In the Injustice Gang.
- My Brain Is Big: His albino gorilla form.
- Pet the Dog: Despite his willingness to shoot to kill, it turns out that he's got a soft spot for 'the uncorrupted'.Ultra-Humanite: "You'll be glad to know that your words - jejune though they may have been - did not fall on deaf ears. I have decided to declare a truce in honor of the holiday."
- Sesquipedalian Loquaciousness: He rarely passes up a chance to show it.
- Spikes of Villainy: On his overalls.
- Super Strength: He's strong enough to briefly grapple with Superman.
- Wicked Cultured: "Injustice for All" shows that he's a big opera fan. "Comfort and Joy" has him destroy an art museum because he hates modern art, and suggest that Flash buy some orphans some literature by Voltaire instead of the fad Tickle-Me Elmo toy he was planning on giving them for Christmas. They end up compromising: Ultra-Humanite reprograms the doll to play a recording of him narrating The Nutcracker instead of fart jokes, and Flash still gets to give it to the kids.
- Voiced by: Virginia Madsen"Let the pain begin!"
Roulette was a conniving entrepreneur who ran an illegal, no-halt, cage fighting league called the Meta-Brawl.
- Badass Normal: Roulette had no powers of her own, but she was endowed with a keen intellect, and surrounded herself with all sorts of security gimmicks, such as death traps and robot security dogs.
- Cleavage Window: Ironically, her comic book counterpart had the same window on her dress, just a bit lower.
- Dark Action Girl: Went toe to toe with Huntress.
- Dragon Lady: Though not being Asian herself.
- Manipulative Bastard: She shrewdly used Wildcat's "mid-life crisis" to recruit him in her event.
- Sinister Shades: Always sporting her sunglasses.
- Smug Snake: She does love to gloat.
Doctor Destiny (John Dee)
Doctor Destiny is the alter ego of John Dee, a low life convict who acquired the ability of ESP.
- Adaptational Dumbass: The Dee of the show is a petty criminal who volunteered for experiments with the Materioptikon. The Dee of the comics was a Mad Scientist who (putting aside the power source turning out to be Morpheus's dreamstone) built the Materioptikon himself.
- And I Must Scream: What he usually inflicts on his victims, and later on the receiving end when he accidentally drugs himself in his fight with Batman, essentially lobotomizing himself as his powers trap him in his mind, humming "Frère Jacques" forever with little awareness of the outside world. He seems to recover by the start of the fifth season, appearing as a member of the new Secret Society.
- Arc Villain: For "Only A Dream".
- Badass Cape: Invoked by his dream outfit.
- Creepy Monotone: Under his new appearance, he speaks in a very soft, very evil voice.
- Disproportionate Retribution: His solution to his wife leaving him after countless years in prison? Go into her dreams after stalking her and her new boyfriend, torment her with heavily implied rape in her dream on top of the explicit Mind Rape, and leave her stuck in her nightmares until she dies from cardiac arrest.
- Dream Walker: After getting his powers. He can enter other peoples' dreams, anywhere in the world even he doesn't know where they are, and there doesn't even appear to be a limit on how many people he can effect at the same time.
- Evil Laugh: He starts laughing very loudly when Green Lantern seemingly gives into his fear.
- Evil Sounds Deep: His voice was on the more nasal end of this trope at first, then he got his powers and dived almost headfirst into it.
- Faux Affably Evil: Initially comes across as being polite and courteous to the warden and staff at the prison... but when his life starts falling apart, the politeness is revealed to be something he uses for tormenting his enemies and victims, as well as covering his pettiness and inferiority complex.
- Hoist by His Own Petard: He ends up accidentally injecting himself with the same drug he was going to use on Batman to make him fall asleep.
- From Nobody to Nightmare: Discussed In-Universe by Batman and Green Lantern. Lantern thinks that Dee is a nobody, at which point Batman brings up Odysseus and his stabbing of the cyclops' eye and how the cyclops could only say that "Nobody" had removed its eye. As it turns out, he was once a petty Lexcorp employee caught for guarding smuggled weapons.
- Killed Off for Real: Possibly. If he was, this is a rare case in which the creators and animators did this by accident. He appears in "Alive" supposedly as part of Luthor's group, although it's likely that this is a colouring error for what was supposed to be Major Disaster.
- Mind Rape: When entering a victim's dreams he subjects them to whatever torments he can come up with. It feels completely real and they can't be woken up by an outsider. If he's not stopped the victim's heart will give out due to the stress from the nightmares overworking it.
- Stalker Without a Crush: Towards his wife by the time he escapes. He's no longer romantically interested in her, just pissed off that she left him behind.
- Underestimating Badassery: In spite of his accurate analyses of the other League members, he didn't take Batman as seriously as he should have done.
- Villainous Breakdown: By the time J'onn takes back half of his captive Leaguers, his powerful, controlled, creepy attitude cracks and turns desperate as he tries to hold on to the rest. Batman closing in on his physical body probably didn't help, either.
- What Happened to the Mouse?: He disappears shortly after his cameo in "Alive", and doesn't reappear after Darkseid explodes the Society's ship, which implies that he's dead. Then again, given how his appearance in that episode is supposedly an animation error, this might not be the case.
- Would Hit a Girl:
- When he bumps into his wife in her dreams, he tortures her into insanity, which kills her even after she's been sedated.
- He also tortures Hawkgirl by making her dream that she's been Buried Alive.
Deadshot (Floyd Lawton)
Deadshot, also known as Floyd Lawton, is an assassin for hire that will take on anyone and anywhere as he has no evil agenda other than his next paycheck. He is also a member of the Task Force X.
- Adaptational Villainy: He was a much more nuanced figure in the comics, complete with a Morality Pet in the form of his daughter. Here he's just an unusually talented hitman with no nuance, nothing more than a gun for hire.
- Badass Normal: Deadshot has no powers, he's just an incredibly talented marksman.
- Boxed Crook: As a member of Task Force X.
- Cold Sniper: A master marksman with no qualms about killing.
- Comic-Book Fantasy Casting: Michael Rosenbaum's voice for Deadshot in based on an impression of Kevin Spacey.
- Creepy Monotone: Deadshot has a flat, deadpan voice.
- Deadpan Snarker: He has a very dry wit, and the borderline monotonous voice helps.Superman: You tried to kill Aquaman. Why?
Deadshot: Gee, I don't know. Why would a hired gun try to shoot somebody? Could it be because someone paid me to?
- Faux Affably Evil: As Plastique discovers to her cost, his jovial nice-guy act is just that; an act.
- Improbable Aiming Skills: The reason he's so dangerous is that he's good with any weapon, at one point coming close to killing Batman.
- Jerkass: He treats everyone like crap and jokes about killing people.
- Karma Houdini: Possibly — only possibly. He's never seen again after "Task Force X", so presumably he's still serving out his five years of incredibly dangerous suicide missions as 'community service'. Although since Captain Boomerang was released, it's possible he was too.
- Professional Killer: He murders people just for money.
- Ship Tease: He briefly has moments with Plastique. Too bad he betrays her.
- The Sociopath: Lawton will kill anyone if is really convenient for him.
- Villainous Crush: He has one on Wonder Woman, offering information if she would "make it worth [his] while."
Chronos (David Clinton)
David Clinton was a small time physics professor from the future Gotham City who developed the technology to travel in time as Chronos.
- Adaptational Badass: This Chronos is way more powerful than his comic book counterpart from The DCU.
- Age Lift: Technically, as the comics David Clinton was a present-day character. This version is from the era of Batman Beyond, which would make him a kid at most in the present.
- Arc Villain: Of "The Once and Future Thing".
- Awful Wedded Life: David's marriage to his wife Enid was so awful that it led to him becoming a supervillain in the first place.
- Bad Boss: Makes his underlings praise him as a god and if they disappoint him then he'll punish them.
- Bitch in Sheep's Clothing: He pretends to be an ally to the League when they time-travel back to The Wild West to retrieve his time-belt, but revealed that he used them to gain his powers back.
- Boisterous Weakling: He's very over-the-top upon embracing his villainy, but he still can't win a straightforward fight.
- Butt-Monkey: Due to being a Henpecked Husband at first.
- Collector of the Strange: Of historical relics. So many, in fact, that he conquers the Gotham City of Batman Beyond just to have a place to keep them all.
- Conqueror from the Future: In a sense. He's native to the time period of Batman Beyond, so he's from "the future," but the time period he ends up conquering is his own. Fulfills the trope's main sense though, in that time travel is his instrument for domination.
- Creepy Blue Eyes: He has very sinister blue eyes.
- Cut Lex Luthor a Check: Initially, he only uses his time belt to accumulate a personal collection. When Enid lampshades how stupid this is, he decides to use it for grander things...and quickly jumps off the slippery slope.
- Domestic Abuser: Once he gains great power, he doesn't hesitate to nonchalantly threaten his wife Enid, and it's implied that he had his mother-in-law placed in a torture machine.
- Drunk on the Dark Side: When he really starts indulging in his new power, he goes clean off the deep end.
- Evil Is Petty: He became a time-traveling crime lord just to improve his low self-esteem, and most importantly to spite his bitchy wife.
- Evil Overlord: Of future Gotham.
- Faux Affably Evil: He has certain childlike qualities that make him endearing, but it turns out to be an Enfant Terrible kind of "childlike".
- From Nobody to Nightmare: He starts out as a comical loser stuck with a job and a wife he hates. But with his time machine, he becomes a successful supervillain.
- A God Am I: He takes to calling himself "the master of time and space" after he gets Drunk on the Dark Side. He later gets the idea of gaining literal godhood by going way back to the beginning of the universe, but fortunately he fails to achieve that.
- Godhood Seeker: Ultimately attempts this, but fortunately fails thanks to John and Batman.
- "Groundhog Day" Loop: This is his final fate; Batman defeats Chronos by ensuring that he never became a villain in the first place. He sabotages the time-belt so that David is stuck in an endless time-loop of arguing with Enid for (apparently) all eternity.
- He Who Fights Monsters: He started out as a loser who was emotionally abused by his wife and looked down upon by others, but after using his time-travel equipment to benefit himself, he grows into an even worse person.
- Henpecked Husband: Initially, but after David becomes Chronos it's downplayed. Using threats to keep her in check, Enid ends up becoming the more henpecked of the two. Though she still sneaks in some of her trademark snarkiness.
- Hero Killer: Chronos and some of his Jokerz actually manage to kill several Justice League members. But because this was a time travel episode, their deaths are all reversed at the end.
- Ineffectual Sympathetic Villain: Gradually subverted. While he does start out as a very pitiable underachiever, he becomes much less sympathetic (not to mention a hell of a lot more competent) as he descends into evil.
- Jumping Off the Slippery Slope: After getting abused by everyone so much, he snaps and grows into the most dangerous villain the Justice League has ever faced.
- Laughably Evil: His backstory and motives are rather ridiculous compared to most of the other villains on the show. Though that doesn't stop him from being a fairly scary evildoer in his own right.
- Mad Scientist: He's a physicist who created his own time-travel belt, at first using it just to steal forgotten artifacts from the past. But it doesn't take long for him to jump off the slippery slope and go mad with his newfound powers.
- Near-Villain Victory: He comes very close to defeating the Justice League, and almost destroyed the universe when he travels all the way back to the Big Bang.
- Not-So-Harmless Villain: Even though he starts off as a pathetic and wimpy loser, he's intelligent enough to cause a lot of trouble for the good guys (and he even manages to eliminate some of them).
- Obnoxious In-Laws: He does something unspecified but implicitly horrible to his mother-in-law, who was always talking about what a worthless good-for-nothing he was.
- Psychopathic Manchild: He expresses a lot of childish characteristics upon becoming an Evil Overlord.(The sky is literally falling apart)
Batman: Look at the sky!
- Sanity Slippage: He goes crazy after spending several months alone in a jail cell a hundred or so years before his present day.
- Slasher Smile: Has a very unsettling grin when he nearly makes it to the beginning of existence.
- Smart Ball: He managed to play Batman by playing the victim card and pretending to be the League's ally.
- Super Empowering: He gives future tech to the Jokerz, and turns them into a personal army good enough to curbstomp the Justice League.
- Super Loser: The heroes find him sleeping in the same jail cell where he once lived for several months, curled up in a fetal position and sucking his thumb, indicating that beneath the supervillain persona, he's still an insecure and frightened man. As his wife explains it:Enid: "[Because] a loser with a kingdom is still a loser!"
- They Called Me Mad!: He was denied tenure as a Physics professor at Gotham University because of his talk of time travel.
- Time Crash: Accidentally causes one once his Sanity Slippage gets really bad.
- Time Machine: He created a time-traveling belt that he uses to mess around with history.
- Time Master: He has an ability to speed up time at a touch, which he uses to break into a vault on the JLA Watchtower.
- Time Travel for Fun and Profit: His original use for the Time Belt was very benign - he was sneaking back in time to steal historically significant objects that were quite trivial at the time (a famous person's hairbrush, first drafts of famous documents, etc.) Things start going bad when Enid goads him into stealing valuable things.
- You Have Failed Me: He won't hesitate to casually murder his underlings when they disappoint him.Chronos: Do you know what killed the dinosaurs?
Bonk: No, sir.
Chronos: Well, Chucko does now.
The former Kid Sidekick of the Justice Guild, a superhero team from an alternate universe. A nuclear holocaust destroyed his world and his heroes forty years ago, but the fallout gave him Psychic Powers so powerful they allowed him to warp reality to recreate an ultra-perfect illusion of his city at the height of his childhood, before everything went to hell.
- Alas, Poor Villain: While he forced the other survivors to act out mundane roles for 40 years instead of rebuilding, which the ice-cream man said was like a nightmare, he's also a child who lost everything during a nuclear holocaust and tried to recreate the world of his long-gone childhood with his newfound powers. The Justice League express Sympathy for the Devil after learning about his frankly tragic life.
- Ambiguous Situation: After his defeat, it's not exactly clear if he's been killed by the strain from keeping the illusion and combat, or if he's been thrown into a coma or is merely unconscious.
- Anti-Villain: Type 2. Ray isn't so much evil as having long since Jumping Off the Slippery Slope due to suffering something no child should ever go through, and losing his idols at the same time. He did force the other survivors into playing along in his fantasy instead of rebuilding though.
- Body Horror: His true appearance is that of a hideously deformed mutant; including a disproportionately large, bulbous head and an elongated left arm, all a result of exposure to nuclear radiation.
- Canon Foreigner: He was created for the series. Though he's considered an Expy of the JSA villain Brainwave.
- Crapsaccharine World: He's made himself the ruler of a post-apocalyptic wasteland that was devastated by nuclear warfare, using his powers of illusion to make his ruined hometown look like a happy, pristine city (straight of a Silver Age comic book) that never changed.
- The Dog Was the Mastermind: At first, it looks like he's the Kid Sidekick of the Justice Guild. He later turns out to be the true villain of his two-part episode.
- Kid Sidekick: He probably was the Justice Guild's before his world's apocalypse, and remained so in the fake city he recreated.
- Nostalgia Filter: He uses his abilities to fool everyone (and himself) into seeing the ruined world as an idealized 1950s/1960s-style dreamland, looking much like it did when he was a young boy. Though considering that the real version of this place underwent catastrophic events that resulted in World War III, it was probably never that "perfect" to begin with.
- Psychic Powers: Officially, Ray Thompson creates psychic illusions. In practice, he comes off as a Reality Warper.
- Psychopathic Manchild: He's actually a few decades older than what he at first appears to be, and he doesn't take it well after the Justice League and Justice Guild unravel his nostalgic fantasy world.
- Reality Warper: The nuclear radiation gave him psychic powers strong enough to alter reality and recreate an ultra-real simulation of the city and heroes of his childhood. The illusion lasts until Martian Manhunter reads his mind to uncover the truth.
- Stepford Smiler: Beneath Ray's charade as a cute, cheerful Kid Sidekick, lies a deeply disturbed man who survived an apocalyptic war, hiding behind nostalgic memories as an excuse to ignore his pain and suffering.
- Tragic Monster: He was originally a normal kid until the nuclear radiation turned him into a hideously deformed mutant with reality-bending powers. His current self doesn't really look human anymore.
- Tragic Villain: Ray was heavily irradiated by a nuclear bomb which had killed his heroes, friends, family, and everything that he ever cared about. In his insanity he created an illusion of a pre-war world, and used his abilities to trap the survivors into resuming their routines before the bombs dropped. He was seemingly killed when he overused his powers to maintain the illusion, and trying to fight off both the Justice League and the Justice Guild.
- Used to Be a Sweet Kid: That was until his whole world was destroyed and his life was ruined forever. But in his fantasy world, he pretends to still be an innocent happy-go-lucky child.
- Walking Spoiler: Due to the entire plot twist regarding the true nature of Ray Thompson and the world he lives in.
- Woobie, Destroyer of Worlds: He lost his world and his childhood heroes, and was horribly mutated due to an atomic bombing. With his newfound powers, he tried to recreate his world from before the nuclear inferno... while forcing the other survivors to play along in his little fantasy and acting out the same roles for 40 years, instead of even trying to rebuild and move on.
Mirror Master, Captain Cold (Leonard Snart), Captain Boomerang
Members of the Flash's rogues gallery, including Mirror Master, Captain Cold, and Captain Boomerang.
- Adaptational Villainy: In the comics, they were Friendly Enemies of the Flash and had no intention of actually hurting anyone since they were just crooks that wanted money and the Flash is an amicable guy. Here, those pretenses are gone, with an entire episode revolving around them trying to kill Flash at his museum opening on his appreciation day as revenge against him for ruining all their schemes.
- An Ice Person: Captain Cold wields a gun that shoots ice.
- Literally Shattered Lives: Mirror Master suffers from this when he tries to escape into a mirror, only for Batman to shatter it before he can reach the other side of the portal.
- Unexplained Recovery: Mirror Master somehow got his life back together and escaped the police after "Flash and Substance", as he appears with the Legion of Doom in "The Great Brain Robbery".
The Trickster (James Jesse)
- Anti-Villain: He's only a villain because he thinks it's fun due to his mental illness. Flash deals with him by talking to him and asking him to turn himself in afterwards.
- Disabled in the Adaptation: The Trickster is a sane criminal in the comics. Here, he's so out of touch with reality, it takes the Flash pointing out that he's in the costume to realize that he's indeed wearing it.
- Even Evil Has Standards: He was iffy about playing darts in a hospital until the Flash assured him he'd get "the soft kind."
- Fashion-Victim Villain: Has an unbelievably gaudy costume but because of his mental illness, he doesn't even realise he's wearing it.
- First Name Ultimatum: The Flash, like a concerned parent or friend, sternly addresses Trickster by his real name, James, to get through to him.
- Harmless Villain: Not quite harmless, as he does wield a highly acidic "snot gun", but he's generally a docile man that can easily be reasoned with.
- No Medication for Me: Subverted, as James admits that he's been taking them, but only irregularly whenever he feels down. The Flash reminds him that he needs to take them consistently for them to work.
- Practically Joker: More of a ported version of his The Flash (1990) counterpart complete with Mark Hamill voicing him, though a lot more sympathetic.
- Small Role, Big Impact: Although he only appears briefly, the Trickster's scene serves to reinforce that the Flash understands better than most of his fellow Leaguers that not all deranged villains need to be battered and locked up, but respectfully treated like any other human beings that need help.
- Talking the Monster to Death: Rather than letting him get used as a punching bag by Orion, the Flash opts to use compassion and communication to deal with the Trickster. Wally's offer to visit Trickster in hospital and play games with him even convinces James to turn himself in without any blood spilt.
A villain in Gotham City.
- Adaptational Nice Guy: In the comics, the white Bloodsport was a white supremacist. This one is a crazy Conspiracy Theorist.
- Adaptational Wimp: In the comics Bloodsport II was a muscular killer with a large array of weaponry who managed to rack up a lot of victims. This version is a scrawny nutjob who lacks a real arsenal and fails to kill anyone, and just resorts to making threats.
- Composite Character: He uses the costume and weapons of the first Bloodsport (Robert DuBois), but is Caucasian like the Alex Trent version.
- Insane Troll Logic: He insists that John F. Kennedy is still alive, no matter how much people say otherwise.
- Legacy Character: There was another villain who used the name Bloodsport in the DCAU based on DuBois. Both of them wear a red bandanna.
A dimwitted snake-like supervillain-for-hire.
- Butt-Monkey: He never comes out on top in any of his appearances.
- Deadpan Snarker: Whenever he gets partnered up with Solomon Grundy.
- Didn't Think This Through: A major flaw of his, special mention going to when he tried to make Hawkwoman fly him to freedom, not realizing that if he killed her when she stopped in mid-air that he would die as well.
- Killed Off for Real: He's frozen and blown up alongside Grodd's other followers in Alive!
- Race Lift: This version of Copperhead is Latino instead of white.
Morgan Edge was a black market collector.
- Adaptational Wimp: He was at one point the leader of Intergang in the comics. This incarnation is just an eccentric billionaire who ends up getting killed.
- Collector of the Strange: He added Clayface to his collection.
- Death by Adaptation: Morgan Edge remained alive and well in the comics, while this incarnation ends up presumably frozen to death by Killer Frost.
- Killed Offscreen: We don't actually see him getting killed, but since we last see him being followed by Killer Frost and she informs Clayface that he won't bother him or anyone else again, it's more than likely that Killer Frost froze Morgan Edge to death.
G. Gordon Godfrey
- Adaptation Species Change: In the comics, Gordon Godfrey is a Human Alien known as a New God named Glorious Godfrey from the planet Apokolips. Here, as far as we see, he's just a regular human.
- Adaptational Wimp: He's usually a New God named Glorious Godfrey in disguise, which doesn't seem to be the case here.
- Flat "What": His reaction to the sun destabilizing.
- Jerkass: He encourages badmouthing the League so that people can watch his show.
- Laser-Guided Karma: After the League saves the world at the end of the episode, Godfrey is seen having been moved to a poor side of his filming studio with only as many audience members you can could count on your fingers. He tries to apologize, claiming that he only criticizes the League because he cares.
- One-Shot Character: He only appears in "Eclipsed".
- Think of the Children!: He berates Wonder Woman's outfit, claiming that it sets a bad example for children.
- Ungrateful Bastard: His talk show makes ratings by talking about how bad the Justice League is, despite their heroics.
