There are many heroes and villains in the Injustice universe who have not thrown their lot in with either Batman, Superman or Grodd, going it alone on the whole. All can be found here.


Arthur Curry/Aquaman

Species: Human/Atlantean hybrid

Voiced by: Phil La Marr, German Fabregat (Latin American Spanish dub), Wolfgang Wagner (German dub), Cyrille Monge (French dub), Luiz Feyer (Brazilian dub)
My duty is to Atlantis.

The stern, but heroic ruler of Atlantis, who has isolated his kingdom after the Regime forced it into a losing battle against Batman and his interdimensional allies. Aquaman has no love for any surface dwellers, but his ruthlessness makes him more similar to Black Adam and the Regime than he'd admit.

And despite his reputation, Aquaman is a more than formidable fighter, equipped with the lightning of the Trident of Poseidon, a kraken at constant attention, and the unflinching strength water provides all Atlanteans.

  • Adaptational Wimp: This version of Aquaman gets beaten down in a fight with Batman, whom he could normally overwhelm easily. Particularly noteworthy considering Batman had to be somewhat tired after fighting Brainiac.
  • Berserk Button: Aquaman hates the fish-related metaphors and jokes that get thrown at him.
  • Blood Is Squicker in Water: The Threatening Shark fish monster that Aquaman summons in his supermove causes his opponent to bleed into the flooded arena, resulting in this trope.
  • Blue Is Heroic: Has blue highlights in his default color palette.
  • Combat Tentacles: One of his moves has him summon large tentacles from the ground to smack and throw around his opponent.
  • The Comically Serious: A lot of his character dialogues have shades of this.
  • Cool Crown: Has quite a few available as gear options. Notably, one appears to be designed in reference to the Trench if the name is any indication.
  • Didn't Think This Through: Foresight isn't really Arthur's strong suit here, first he doesn't listen to reason which causes Atlantis to be collected, then apparently it doesn't occur to him that teaming up with the Regime against Batman would inadvertently lead to the Regime returning to power.
  • Does Not Like Shoes: He can be barefoot while in combat.
    • Subverted: Some armor options gives him boots to wear, but in the main story, Aquaman walks barefooted, save for some footwraps, to partially protect his feet.
  • Enemy Mine:
    • He is not a fan of the Regime anymore, but he sides with them over the Justice League at the end of the story mode, as he agrees with them that Brainiac needs to die.
    • In Black Manta's Arcade Ending, he sides with them to avenge Atlantis after Black Manta stole its digitized form.
    • Even after siding with them, many intros with Regime members and his Arcade Ending confirm that he will betray them after threats against Atlantis have been dealt with.
  • Everyone Has Standards: In spite of his previous conflicts with Batman, one of his intro dialogues with Robin implies that he is displeased with Damian going against his own father.
    Aquaman: Still, you owe him your loyalty.
  • Foreshadowing: At the end of his and Black Adam's chapter, he kills off Grodd for supporting Brainiac, with Black Adam's unspoken approval. Later, during the final showdown between the Regime and Batman's allies, he sides with the Regime because despite not being with them, his ideas and values line up more with theirs than those of Batman.
  • Gondor Calls for Aid: Brainiac's defeat in the Arcade mode brings the Regime back to power. Fearing that the Regime will attempt to conquer Atlantis again, Aquaman travels to the main universe and asks its heroes to stop the Regime once again.
  • Half-Human Hybrid: One half of him is human, the other half is Atlantean. One of Arthur's interactions with Scarecrow implies he has some insecurities about his heritage, as the latter claims that the Atlantean king's subjects contemptibly refer to him as "Half-Breed king".
  • Hypocrite: He claims that being half-human has taught him compassion, yet he has No Sympathy for anyone outside Atlantis. He says openly and often that the entire surface world can go jump in a lake for all he cares.
  • It's All About Me: Downplayed. He's still trying to be The Good King to Atlantis, but has adopted a firm policy of "Not My Problem" regarding the fate of the surface world, and refuses to join both Batman and Superman. He only joins them in Story Mode when Brainiac collects Atlantis and he can't sit the invasion out any longer.
    Aquaman: Atlantis won't bleed for the Surface World!
  • Kick the Son of a Bitch: Kills Grodd. The game doesn't advocate killing supervillains, but seeing as Grodd sold out the entire planet to Brainiac to save his own skin he more than earned it.
  • Mr. Fanservice: He's a Walking Shirtless Scene, and is very muscular.
  • Pet the Dog: After Hal Jordan helps him fight off Brainiac's forces, Arthur gives Hal his thanks and assures him that he believes him to be trustworthy.
  • Pre-Mortem One-Liner: Delivers one just before he kills Grodd with a trident through the heart.
    Grodd: Stupid humans...
    Aquaman: (after stabbing him in the side with his trident) The people of Atlantis demand justice.
    Grodd: Against Brainiac? Hehe. I've seen his mind... felt his power... he can't be stopped...
    Aquaman: But you can.
  • Prongs of Poseidon: Once again wields his Atlantean trident in battle. His Gear options provide numerous trident designs.
  • Team Switzerland: His initial stance, but his hand is ultimately forced when Atlantis is taken for Brainiac's collection and he joins the alliance between Batman and Superman to save it. When Brainiac is defeated and thinking he is too dangerous to let him live, he takes Superman's side. With that said, his Arcade Ending reveals he had to go back to the Earth Prime that appeared on the first game to ask for help (because Superman is taking over again)... and ask for forgiveness.
  • Threatening Shark: His super move involves knocking his opponent up above the surface of the water, smacking them around a few times with his trident, and having a giant shark-like creature jump up and grab them and drag them back down to the arena.
  • Too Dumb to Live: In his Arcade Ending. Really, dude, Superman pretty much jacked control of Atlantis away from you last year because he seriously thought it'd be a good idea even though you didn't. Now you've helped beat Batman's forces, the only resistance against Superman's Regime. What did you think was going to happen?
  • Walking Shirtless Scene: While he does have some decorations and armored bits around his upper body, the majority of his torso is exposed skin.


Species: Ryutian

Voiced by: Ike Amadi, Ricardo Tejedo (Latin American Spanish dub), Tim Moeseritz (German dub), Frédéric Souterelle (French dub), Maurizio Trombini (Italian), Dláigelles Riba (Brazilian dub)
Our hellish hate will burn you all!

Once a simple family man with a wife and children, Atrocitus is the last survivor of Sector 666, the victim of a massacre by the Manhunters caused by defective programming. Since then, he has been out for the blood of the Guardians of the Universe and any who serve them, going so far as to form his own Lantern Corps, powered by the Red Light of Rage and filled with monstrously angry people who were victims of a great wrong just like he was. Sustained by his Red Lantern Ring in place of his heart and his blood replaced with molten hot plasma, Atrocitus now seeks to fulfill his long-promised revenge, punish the guilty with lethal force and fill the ranks of his corps with new members. His steely gaze now falls on Hal Jordan, prodigal Green Lantern, to be his latest recruit.

Aiding Atrocitus in his endeavors is Dex-Starr, Earth's Red Lantern — a once-ordinary cat who was filled with rage after witnessing the murder of his kindly owner. Now he aids his master in battle through plasma blasts and other assists.

  • Adaptational Attractiveness: A slight example. His face looks much more humanoid than he's usually depicted in the comics, and lacks the huge mouth full of sharklike teeth.
  • Adaptation Origin Connection: ...Or maybe not. His bio on the official website says that this version's people were oppressed by the Sinestro Corps instead of his traditional Start of Darkness, but all Atrocitus' remarks on his past point towards his normal origin story, including claims the Manhunters slaughtered his people and that his rage has burned for eons. If anything this seems to be The Artifact.
  • Anti-Villain: He's not much of a bad person, just obsessed with punishing the wicked and unable to calm himself due to his ring. It helps that plenty of the characters in this story and the DCU at large legitimately deserve retribution for various misdeeds. In his Arcade ending, he pulls a full Heel–Face Turn after Proselyte uses his moment of remorse to calm him.
  • And This Is for...: In one of his possible clashes with Supergirl.
    Atrocitus: This is for calling me a baby!
  • Armor-Piercing Question: To Hal Jordan while attempting to corrupt him.
    Atrocitus: You may have overcome your fears, but you still betrayed the Green Lanterns. Hurt your allies. How could you ever forgive yourself?
    Green Lantern: I... I can't...
  • Badass Creed: He recites the latter half of the Red Lantern oath while performing his supermove, which he turns into a Punctuated Pounding.
    Atrocitus: Together with our hellish hate... We'll burn you all... That is your fate!
  • Berserk Button: Given that he has a Hair-Trigger Temper, this is inevitable. The most prominent ones, however, are calling him a baby and making fun of his cat.
    Blue Beetle: Who calls their cat "Dex-Starr"?
    Atrocitus: You're all done mocking him!

    Supergirl: Ready for naptime, Baby?
    Atrocitus: You'll not ridicule me again!

    Supergirl: Red jewelry's kinda for old ladies.
    Atrocitus: MOCK ME AT YOUR PERIL!
    • In the comic, he invokes this when Lobo kicks Dex-Starr, but now that Lobo has a Green Lantern ring, that rage isn't enough to stop him.
  • Big Red Devil: What his design is clearly going for. This further enhanced by various gear options that give him hats with devil horns.
  • Blade Below the Shoulder: Forms a blade of solidified blood on his forearm for several attacks. His super starts with his opponent being Impaled with Extreme Prejudice by one.
  • Blindfolded Vision: Some of his headgear covers his eyes, but he still operates as normal. This may be symbolic of blind rage and/or justice.
  • Bloody Murder: The majority of Atrocitus' moveset uses blood plasma, ranging from a Breath Weapon to a hardened Blade Below the Shoulder to a whirlwind of blood that draws opponents closer.
  • Blue-and-Orange Morality: His entire theme is about embracing, focusing, and channeling rage, but Atrocitus seems to have standards in how you do that, criticizing his opponents for both for insufficient rage and using their rage foolishly.
  • Breath Weapon: Atrocitus likes to fire blasts of his plasma-blood from his mouth, which doubles as a Vomit Indiscretion Shot.
  • Butt-Monkey: In battle intros, he's on the receiving end of a constant stream of trolling from the more lighthearted characters due to his The Comically Serious nature.
  • Can't Kill You, Still Need You: His rationale for not killing Hal Jordan. By rights he should be killing him for everything he did as a member of the Sinestro Corps/Regime and he notes Dex-Starr wants to rip his throat out, but it would be a waste to pass up such a promising recruit for the Red Lantern Corps, and he's seen that Hal can switch sides already.
  • Clingy Costume: As per the source material, his Red Lantern ring. He tells Batman that he would die if it were removed, presumably for the same reasons (that his heart has stopped and he would go into cardiac arrest without it). Batman decides to avoid that.
  • The Comically Serious: A lot of comedy comes as a result of him having No Sense of Humor and being perpetually furious at absolutely everything.
  • Continuity Snarl: His bio claims the oppression of his homeworld by the Sinestro Corps was the cause of his rise to villainy, but one of his comments to Batman is that his rage "has burned for eons" — which given the rise of Sinestro's Corps is only a relatively recent event, suggests the more traditional Start of Darkness involving the Manhunters.
  • The Corrupter: Atrocitus has come to Earth looking for candidates to join the Red Lantern Corps. He intends to stoke the flames of rage in people, and Hal Jordan is one of his targets. As shown in the story mode, he is fully capable of not only instilling rage in those he burns with his plasma, but he can also give Hal Jordan bursts of rage without even being present on the planet.
  • Despair Event Horizon: When his family died, something died inside him as well.
    Atrocitus: My heart died on Ryut!
  • Does Not Like Shoes: Injustice 2's portrayal of Atrocitus goes about barefooted, throughout the game. His armor, also has a rather organic, exoskeleton quality to it, possibly implying that he actually goes without clothes as well. Some armor options give him the appearance of boots over the tops of his feet, but if knocked down, you can see the armor has no soles, exposing his feet.
  • The Empath: His Red Ring allows him to observe people's rage and hatred in all its forms, including rage caused by grief and resentment for past wrongs. He often brings up specific examples of what angers people in his intros.
  • Enmity with an Object: His hatred of the Guardians and their corps is apparently so great that it extends to the color green itself, as he says to Green Arrow and Swamp Thing.
  • Even Evil Has Standards: He's more extreme than evil, but he still has limitations which are true to the spirit of this trope.
    • He sees what Superman's done to Earth as glorified slavery.
      Atrocitus: Earth's hero turned villain.
      Superman: Justice requires order.
      Atrocitus: Looks more like oppression.
    • He finds the Joker and Brainiac utterly disgusting, calling the former the vilest creature he has ever metnote  and saying the latter is worse than the Manhunters, vowing to avenge their many victims.
      Atrocitus: You'll shed no more blood, Joker!
      Joker: But my masterpiece isn't finished yet!
      Atrocitus: Nor shall it ever be!

      Atrocitus: You're worse than the Manhunters!
      Brainiac: I collect planets, not destroy them!
      Atrocitus: A Distinction Without a Difference!
    • In his arcade ending, he's horrified when killing Brainiac destroys all the cities he's taken along with him.
  • Evil Mentor: Downplayed. He's an Anti-Villain, and wants to convince potential recruits to his corps to give into their rage and hatred and pursue it in the name of Revenge and Pay Evil unto Evil.
    Atrocitus: Your rage is the Joker's legacy.
    Cyborg: I'll never get over Metropolis!
    Atrocitus: I'll show you how best to use it.
  • Evil Sounds Deep: His voice is raspy and low-pitched.
  • Eye-Obscuring Hat: Several of his gear pieces hide his eyes.
  • Failure-to-Save Murder: Seems to be a secondary beef he has with the Green Lantern Corps.
    Atrocitus: The Green Lanterns are failures!
    Green Lantern: Yeah, with our saving lives and all.
    Atrocitus: Who avenges the ones you can't save?
  • Giant Space Flea from Nowhere: Only appears once in the story, completely out of nowhere, to recruit Green Lantern into his Corps. He disappears after he is defeated, and never shows up again. Considering he has no ties to any of the main factions and his presence has no weight on the story whatsoever, it sure comes off this way. His only reason for being in that part of the game at all seems to be to justify him being in the game's roster in the first place.
  • Hair-Trigger Temper: He's a Red Lantern. It's kind of a given.
  • Hard Light: While his usual attacks are plasma-blood, he can zap short rays of Red Light from his ring. Dex-Starr's support can also involve shooting balls of Red Light or even forming a protective shield with it.
  • Heel-Face Mind Screw: Downplayed in his Arcade ending. He was already horrified by the destruction he unleashed on the world, but Proselyte sealed it by calming his rage. To be fair, he was already getting mind-screwed by his ring before that.
  • He Who Fights Monsters: His family and people were killed by the Manhunters, causing him to go down a path of villainy, which is Not So Different from Superman's Roaring Rampage of Revenge in the last game after he lost his family due to the Joker's sick schemes.
  • Here We Go Again!: The second Green Lantern villain to try bringing Hal Jordan over to his side, after Sinestro succeeded in the prequel comics.
  • I Am the Noun: Wrath Incarnate, in fact.
  • Impaled with Extreme Prejudice: His super starts by forming a red blade, stabbing his opponent through the chest, and lifting them up before punching them away and summoning The Butcher.
  • I Will Show You X:
    Atrocitus: I'll show you hellish hate!
  • Large and in Charge: The leader of the Red Lantern Corp, and one of the larger characters in the game.
  • Last of His Kind: As he'll happily explain if you ask, the rest of his people were killed by the Manhunters, for which he has sworn eternal vengeance against their masters, the Guardians.
  • A Lighter Shade of Grey: While Atrocitus looks like a Big Red Devil, his goals boil down to seeking retribution for legitimate wrongdoings, and bringing vengeance upon the guilty. It's something of a step up from Superman's desire to enslave the world, and Grodd and Poison Ivy's desires to wipe out humanity.
  • A Load of Bull: Atrocitus' super involves summoning The Butcher, the bull-like Anthropomorphic Personification of the Red Light of Rage.
  • Lone Wolf Boss: Atrocitus shows up out of nowhere during Green Lantern's chapter to forcibly recruit him to the Red Lantern Corps with the help of Dex-Starr. He has no ties with either the Regime, the Society or Brainiac, and he goes away after being defeated never to be seen again.
  • My God, What Have I Done?: His Arcade ending, where he realizes he's destroyed most of the Earth in the process of killing Brainiac. After Proselyte calms his emotions, he does everything in his power to ensure such a tragedy will never happen again.
  • Mythology Gag: His intros make a few references to the Blackest Night, including a literal namedrop and certain characters joining the various Lantern Corps.
  • Not So Different: Him and Superman, to an incredible degree. Both of them became what they are and were started on the path to villainy by a desire for revenge after suffering a deep personal loss — Atrocitus was an ordinary man with a wife and children who lost both and witnessed the destruction of his home system, and went on a Roaring Rampage of Revenge, much like how Superman lost Lois, their child and Metropolis to the Joker's sick schemes. Both of them wish to punish the guilty and have no time for anyone who gets in their way, and like Atrocitus, Superman is (formerly) the Last of His Kind. Each is characterized as a tragic Woobie, Destroyer of Worlds. Atrocitus acknowledges this in-universe in one of his opening quotes with Superman.
    Atrocitus: The Earth trembles from your wrath. [...] That same rage created me.
  • Pay Evil unto Evil: Often cites this as his motivation to fight villainous characters, telling them he's there to avenge their victims. His Ladder Ending serves as a Reconstruction of this trope. Atrocitus kills Brainiac for his crimes, but to his dismay the entirety of Brainiac's collection is destroyed and the people inside along with it. His Red Lanterns are filled with rage at him and try to kill him, but he is saved by Proselyte, the Emotional Entity representing the Indigo Light of Compassion, who uses his guilt to calm him and show him a better way: balancing the Emotional Spectrum. There is room for him and his Red Lanterns to punish those who truly deserve to die, so long as it is tempered with compassion for those who deserve that instead.
  • Pet the Dog: If he depletes the enemy's first life bar while Dex-Starr is active, his victory pose may have him sitting on Atrocitus' arm while he gently strokes him.
  • The Power of Hate: As a Red Lantern, he's fueled by rage and hate. He often espouses the power to his opponents as part of his recruiting strategy.
  • Promoted to Playable: He previously made a cameo appearance in the first game in the Metropolis stage where he's seen fighting Kilowog.
  • Psychopathic Manchild: Supergirl certainly seems to believe so, judging by how she constantly calls him/compares him to a baby. The fact that he doesn't take too kindly to this doesn't help his case.
  • Ramming Always Works: His supermove summons The Butcher, who charges horns-first into an opponent who's backed up against a rock outcropping, smashing them through it.
  • Red Is Violent: Being a color that represents rage, violence and aggressiveness as well as fire and blood, red is a very suitable color for Atrocitus and his Corps.
  • Right-Hand Cat: Dex-Starr, the feline Red Lantern of Earth, assists him in battle as his special trait. He also appears in intros where Atrocitus speaks first.
  • Shoulders of Doom: His known Gear options include various and consistently unsubtle pauldrons.
  • Took a Level in Kindness: His Arcade ending depicts him learning the value of compassion after his Red Lanterns are pacified by Proselyte, the living embodiment of compassion. He even decides to unite the other Lantern Corps under a single banner.
  • Unstoppable Rage: He's absolutely furious, thanks to his ring. As a Red Lantern, his powers are fueled by this trope.
  • Unwitting Instigator of Doom: In his Arcade Ending, his victory over Brainiac accidentally causes all the worlds Brainiac collected, along with their inhabitants, to be destroyed, much to his horror.
  • Villain Takes an Interest: Again, Atrocitus is on Earth to bolster the ranks of his Corps. In particular, he wants to turn Hal Jordan into a Red Lantern, though he has an interest in recruiting Superman and Batman as well.
  • Vomit Indiscretion Shot: As is common of the Red Lanterns, his primary form of attack is vomiting up Blood from the Mouth in the form of highly corrosive plasma.
  • What the Hell, Hero?: In one of his battle intros with Cyborg, he calls Victor out for having resentment toward his father for causing his transformation, and considering how Silas Stone gave him his cybernetics to save his life, Atrocitus may have a point.
  • Woobie, Destroyer of Worlds: Much like Superman, Atrocitus is a sad figure whose extremism and unreasoning rage are the result of the pain he has suffered and a not-unreasonable desire for revenge that sometimes goes too far. As much as he tries to hide it, he is still the shell of a good man who lost everything.

Vril Dox/Brainiac

Species: Coluan

Voiced by: Jeffrey Combs (main game), Dee Bradley Baker ('Lines Are Redrawn' trailer), Jose Luis Miranda (Latin-American Spanish dub), Walter Alich (German), Lionel Tua (French), Antonio Paiola (Italian), Antônio Moreno (Brazilian dub)
Such folly and futility in the grand design.

An alien with a twelfth-level intellect, Brainiac has amassed so much knowledge and technology from throughout the universe that the armies of Earth are nothing to him alone. He could destroy the world in an instant, but destruction is of no special interest to him. He only killed Krypton and the millions of other worlds he visited so that the knowledge he collected from them would be all the more valuable.

His tentacles are strong enough to toss around Kryptonians, his satellites are ever ready to fire into the battle, and his fists are more than able to crush the skulls of primitive species.

  • Above Good and Evil: How he sees himself. Brainiac considers morality to be beneath him. Nevertheless, he is chuffed to hear the Lords of Order have decided to endorse him.
    Doctor Fate: My directive is to aid you.
    Brainiac: Those that command you are wise!
  • Adaptational Badass: His comic counterpart is still a huge threat, but this Brainiac takes it Up to Eleven. For one, his intro dialogues with Atrocitus (plus Scarecrow's Arcade Mode ending) reveal that he's destroyed billions of worlds, as opposed to thousands in the comics. His intro dialogue with Green Arrow also has him implying he's become a full Multiversal Conqueror, instead of a mere Galactic Conqueror, which is seemingly confirmed by Raiden's ending. In general the game builds him up as the single most dangerous being in the DCU next to Darkseid, while in the comics there's at least a few villains generally above him.
  • Adaptational Late Appearance: His appearance in Injustice 2 is apparently the first time he's been to Earth in this continuity, during which Superman and Batman are at least in their 40s (Damian, Batman's son by Talia, is stated in one of his intros to be 18) and have had careers in superheroics for decades. In the comics, he's Superman's Arch-Enemy and shows up relatively early on (or at least his drones do).
  • Adaptation Origin Connection:
    • In this universe, Brainiac destroyed Krypton after retrieving two of its cities (Argo City and Kandor) and is only now headed to Earth because he only recently heard of "the Last Son of Krypton."
    • He also is responsible for the existence of Grid in this setting, creating a separate body for him instead of Grid creating a body for himself out of the cybernetics he forcefully rips from Cyborg's body.
    • According to Superman's ending to the main story mode, he also has prisoners from Daxam and Czarnia, indicating that, among other things, he is connected to Lobo's origin story as well.
    • The comics reveal he's possibly the creator of Amazo- or at least, whoever created Amazo used some of his technology to do it.
    • In his intro dialogue with Batman, Hellboy comments that he's only in this universe because he "got shanghaied here by Brainiac." Suffice to say, he's not pleased about this.
  • Arch-Enemy: To Supergirl. He killed her mother, destroyed her planet, and is also partially responsible for her cousin's fall from grace. As Superman points out, she has more reason to want him dead than anyone.
  • Asshole Victim: He's Killed Offscreen by Superman in the Absolute Power ending. Considering all the people he's killed, digitized and imprisoned, it's hard to feel sorry for him. He also dies in several of the Ladder Endings.
  • Attack Drone: One of his attacks has him summon a small drone that flies across the screen and shoots the opponent.
  • Ax-Crazy: Paints himself as a being who only wishes to collect knowledge. In truth, he's a vicious Omnicidal Maniac.
  • Badass Boast: Gets off an epic one with just three words when Darkseid brags he is indeed a god, from fiery Apokolips:
    • From the main story:
    Brainiac: I match your strength, you cannot match my intellect! You are only a Kryptonian, of which I have killed billions!
    • A more generic one that appears in a lot of his combat intros:
    Brainiac: Facing me... is a fatal error.
  • Badass Bookworm: Alien scientist who values knowledge, and he's so powerful that it takes the combined efforts of Batman and Superman to stop him.
  • Bad Boss: Treats his followers an air of politeness but doesn't think twice about turning on them.
  • Be Careful What You Wish For: He wants the universe all to himself. At the end of Flash's Arcade mode, Flash decides to give him just that by dropping him off near the end of time.
  • Big Bad: The primary source of conflict in Injustice 2.
  • Big Bad Ensemble: With Superman. Though Brainiac is the most active threat by kicking off the plot to begin with, and both sides fiercely oppose each other, Superman is fully intent on restoring the Regime and becoming a Multiversal Conqueror when all is said and done.
  • Big Brother Is Watching: He reveals that he absorbed Brother Eye, Batman's surveillance network and CPU for the Batcave, into his neural network, allowing him access to data on Batman and his allies.
  • Blasphemous Boast: He's got his share.
    Brainiac: Are you a god?
    Doctor Fate: Close enough to one!
    Brainiac: Then I am as well.

    Brainiac: Diana of Themyscira.
    Wonder Woman: By the gods, I will defeat you!
    Brainiac: No gods can save you.
  • Can't Kill You, Still Need You: Batman and his allies make this argument after Brainiac's defeat, believing that even if they thought he should be an exception to the no-killing rule, they need him to help figure out how to safely restore the captured cities, an argument backed up by the fact that Superman's first attempt to restore the cities via controlling Brainiac's ship himself resulted in some of the cities being accidentally deleted from the ship's memory.
  • The Chew Toy: As the final boss of Ladder Mode, beating him is always the initial focus of any characters' Ladder Ending, and as such he is constantly subject to unpleasant fates of varying stripes, among them: being killed by characters like Atrocitus, Grodd, the Joker, Wonder Woman, and Superman for varying reasons, being Mind Controlled by and getting the Kiss of Death from Poison Ivy and getting Mind Raped by Scarecrow. Being beaten down and tied up with his own Combat Tentacles is the nicest thing that happens to him, but since he's such a vicious bastard in Story Mode you'll virtually always side with his tormentor.
  • The Collector: As always, Brainiac seeks knowledge by collecting the major cities of inhabited planets, then destroying the planet itself. As he desires this knowledge to be exclusive, Green Lantern John Stewart will sometimes compare him to the Orange Lantern Larfleeze, while Darkseid ridicules him, claiming that knowledge is useless without power.
  • Combat Pragmatist: Brainiac is a dirty fighter. His Secret A.I. Moves for his SNK Boss mode involve manipulating parts of his ship to crush his opponent, planting a mine to electrify the floor, or unleashing laser-shooting drones. Meanwhile his unlockable abilities include throwing up a drone to shoot his enemy and calling in a Kill Sat shot from his spaceship. His supermove is another good example: he calls down his drones to hold his opponent in place, then nukes them with his spaceship's main gun.
    • In the Story Mode, he easily defeats Supergirl by ambushing and restraining her with his Combat Tentacles, and incapacitates Superman by blasting him from the safety of his ship skull ship with a Wave-Motion Gun.
  • Combat Tentacles: His Weapon of Choice are eight mechanical limbs that sprout from his back like Doctor Octopus. Naturally, his fighting style primarily makes use of these.
  • The Comically Serious: All the humor from his pre-fight dialogue comes from his no-nonsense attitude contrasting with the sillier or snarkier characters.
  • Composite Character: He's mostly based on his Post-Crisis, post-Superman: Brainiac incarnation, but has the Powered Armor and Combat Tentacles of his New 52 incarnation.
  • The Computer Is a Cheating Bastard: When fought as an arcade boss, Brainiac has access to moves that his playable self doesn't and all his custom moves. One of these is planting a mine on the ground and electrifying the floor or manipulating parts of the ship to attack the opponent. Justified since the boss fight takes place inside his Skull Ship, where he has complete control of its surroundings and you are pretty much forced to fight in his terms.
  • Conflict Killer: The reason why he is the Big Bad in Injustice 2. The story is mostly a three-way conflict between the Insurgency vs the Regime vs the Society. The moment he shows up with the intention of annihilating planet Earth, he becomes a threat to everyone else.
  • Control Freak: True to his comics incarnation, this he reason why he seeks to make sure that the only life in the multiverse is what's contained shrunken in his ship. Also the reason he attacks Earth at all; that any Kryptonians still exist outside of his control severely annoys him. Additionally, this character trait is referenced constantly in his in-game dialogue:
    Brainiac: (grab) You belong to me.
    Brainiac: (clash quote) I take what is mine.
    Brainiac: (round win) Your world is mine.
  • Creepy Monotone: Much like many of Jeffrey Combs' roles, his voice is more-or-less entirely drained of emotion. It goes hand-in-hand well with his sociopathy.
  • Cybernetics Eat Your Soul: Invoked. He's an evil stoic cyborg who encourages fellow cyborg Cyborg to "abandon [his] humanity" to become stronger.
  • Death from Above: Can summon lasers from his ship in gameplay, even if the fight is inside his ship.
  • Deflector Shields: Has one his ship that's virtually impenetrable, even Superman can't break it.
  • Did You Just Punch Out Cthulhu?: Heavily implied in his intro dialogue with Darkseid to have killed or captured many gods.
  • Difficult, but Awesome: Brainiac is very rarely seen online, quite possibly the least played character period, but is considered high tier regardless. Most of his combos require precise timing, he's slow, and he lacks any projectiles besides his trait (without unlockable abilities), but his air maneuverability and mix-ups are surprisingly good, his normal melee attacks have great range, and when utilized properly he hits like a truck.
  • Disappointed by the Motive: He has a tendency to incur this reaction, given that his entire raison d'etre involves stealing a world's knowledge and casting its people aside to make sure that knowledge is exclusive. Darkseid scoffs that knowledge is useless without power, and John Stewart points out he could just study those worlds instead, before comparing him to Larfleeze.
  • Disc-One Final Boss: The Story mode continues even after he is defeated, setting up the final conflict between Batman and Superman.
  • Distinction Without a Difference: He doesn't destroy planets, he just steals all their cities and most of their inhabitants, then callously tosses aside whatever's leftover. Atrocitus calls him out on this and even invokes this trope, see above.
  • The Dreaded: As in the source, Supergirl is terrified of him, and thinks their only hope is to release her cousin. Even then, Bruce notes Superman himself fears him too, and Superman warns him that without his help, they have no hope of beating him. Also, in Green Lantern's intro dialogue, he states that the Guardians specifically warned him about Brainiac.
    • The Battle Simulator Brainiac's ending states that because of him, Coluans are hated and feared even if they are nothing like Brainiac, which was his motivation to stop him.
    • Grodd regards him as basically unstoppable and invulnerable.
    Aquaman: The people of Atlantis demand justice.
    Grodd: Against Brainiac? Heh heh. I've seen his mind... felt his power... he can't be stopped.
  • Extremity Extremist: All of his melee special moves, heavy attacks, and basic combo strings make use of his tentacles and legs, with his primary combo starter being a dive kick. He very rarely uses his fists, usually as minor blows in combos.
  • Evil Is Bigger: One of the tallest and bulkiest characters in the game.
  • Evil Sounds Raspy: He has a raspy, vaguely mechanical voice.
  • Eviler Than Thou:
    • A bigger threat than both Superman and Gorilla Grodd, to the extent of forcing an Enemy Mine between hated enemies to stop him.
    • He and Darkseid both see themselves as superior to the other. Brainiac is unimpressed by Darkseid's track record with fighting the forces of Earth and says his status as a god doesn't matter as much as he thinks, while Darkseid insists that no amount of intellect can protect Brainiac from his Omega Beams and his motives for villainy are pathetic.
    • Atrocitus opines that Brainiac is even worse than the Manhunters, either because of the sheer number of worlds he's destroyed, or possibly because the Manhunters only kill people and destroy planets, while Brainiac leaves the cities and peoples he absorbs trapped in his collection with no way out.
    • In his intros with Blue Beetle, he comments that he's defeated the Reach before.
    • Invoked in Black Manta's Arcade Mode ending — he comments that if he can beat Brainiac, then taking out the Regime should be a cakewalk.
    • In some of his intros with the Joker, Brainiac opines that the Ax-Crazy Monster Clown is way too worse than he is, and that he's a cancer to his collection who needs to be neutralized.
  • Evil Is Petty: One of Firestorm's intro lines to claim Professor Stein is smarter than Brainiac. Brainiac takes that as a challenge and asks if Stein has discovered the source of dark matter. Firestorm admits he hasn't, but he's working on it.
  • Faceship: He still has skull-shaped spaceships at his command.
  • Failure Is the Only Option: Despite what the Lords of Order believed, there's no ending in Story Mode or Battle Simulator where Brainiac succeeds in collecting Earth, nor is there a point where he gets any revenge on whoever defeats him. Even his attempts to bargain with his triumphant opponents in the Ladder Mode endings have ended only with his death.
    • Subverted by his alternate universe counterparts. Earth-1212 Brainiac from the Battle Simulator not only collected Earth, but 17.6% of the entire multiverse. One of his Mirror Match intros also has another alternate universe Brainiac claiming to have collected everything in his universe, including Earth.
  • Faux Affably Evil: He talks in a soothing, polite and almost friendly voice. This does not, in any way, cover his monstrous actions.
  • Fatal Flaw: Lack of foresight. For all his intellect, Brainiac is clearly someone who's used to all his plans going off without a hitch and therefore rarely, if ever, has any Plan B to rely on when they fail. For starters, his plan to draw the Flash out to have the Society ambush and kill him failed, allowing Barry to join up with Batman. When Cyborg and Catwoman took back Brother Eye from him, he dismisses it as a minor victory and doesn't bother trying to take it back. He also clearly didn't anticipate Superman defeating him and his technopathic connection to his fleet disrupted, which nearly caused his ship to crash and almost caused him to lose his collected cities. Scarecrow even alludes to this, saying his lack of fear is actually "a lapse born of arrogance".
  • Gameplay and Story Segregation: Brainiac's ship stage has two noticeable examples:
    • One, his super-move involves using his ship's main cannon to nuke his opponent... even if they're inside his ship.
    • Two, the stage transitions both involve the ship's tentacles attacking whoever got knocked through the transition. Makes sense if Brainiac isn't selected (then he'll just be on his throne, directing the ship), or if Brainiac is the one doing the hitting. If Brainiac is the one being knocked through, however, he's technically hitting himself- as he says himself, the ship is basically an extension of his body. This occurs even with the SNK Boss version of Brainiac, who does manipulate those same tentacles to attack outside of the transition.
  • Genius Bruiser: Twelfth-level intellect and boasts the strength to match a Kryptonian in a physical brawl.
    Brainiac: I match your strength. You cannot match my intellect!
  • Greater-Scope Villain:
    • To Superman and the Regime in the first game, in a sense. While the Joker was the one that pushed Superman to darkness, the latter would never be on the planet in the first place if he hasn't destroyed Krypton. In addition, he separated his cousin Kara, who was supposed to guard and protect Kal-El, which would have turned him out in a much different path than he took.
    • The prequel comics revealed that he is this for the League of Assassins, since it's revealed that Coluan technology was used to create AMAZO in their plan to destroy humanity. He's also the mastermind behind the Red Lantern attack on Oa.
    • In turn, Doctor Fate notes that the Lords of Order are backing Brainiac because balance was compromised by the Regime's defeat and have forbidden Dr. Fate from intervening, as stopping him would trigger an even worse catastrophe.
  • Glowing Eyes of Doom: He has cybernetic eyes that glow in the dark, giving him a pretty creepy stare, especially in shots with low lighting.
  • Immune to Mind Control: As a result of his powerful mind, neither Grodd nor Ivy can control him.
  • Insufferable Genius: He's the smartest being in the universe and reminds everyone how smart he is in every other intro dialogue.
  • Ink-Suit Actor: His facial structure resembles that of his voice actor, Jeffrey Combs.
  • Jerkass: Not only is he a monstrous Planet killer, he's also a huge ass. Observe, for example, his round win and clash quotes when fighting Supergirl:
    (round win)
    Brainiac: Your mother would be disappointed.
    Supergirl: For the people of Krypton!
    Brainiac: Your abject failure?
  • Kick the Dog: Kills Kent Nelson after the Helmet of Fate is destroyed.
  • Killed Offscreen: By Superman in the Absolute Power ending.
  • Kill Sat: Brainiac's Super Move involves his mothership blasting one on a restrained target (this also happens in the final boss which takes place inside his own mothership). Also, one of his attacks has him calling down a purple laser from the sky.
  • Knight of Cerebus: The Story Mode takes a turn for the dark whenever he's on-screen.
  • Kryptonite Factor: According to Superman after he's defeated the first time, attacks on his fleet and ship weaken his ability to fight personally, which may be the Achilles' Heel to his own technopathic connection to his technology.
  • Lack of Empathy: Towards everything in the universe that isn't knowledge.
    Atrocitus: Trillions demand vengeance!
    Brainiac: Those not collected?
    Atrocitus: Those you slaughtered!
  • Leitmotif: A brass chord plays every time Brainiac does something vile, and is used during his Super Move.
  • Legacy Character: If set up in a Mirror Match, the second Brainiac will claim to be either an alternate universe Brainiac who defeated everyone in his home universe, Brainiac 5 in disguise (a descendant of Brainiac from the 31st century), or Brainiac 6 (another descendant from further down the line). In the latter case, Brainiac 1 will challenge Brainiac 6 to a battle in order to prove his worthiness.
  • Load-Bearing Boss: When he's defeated in Arcade Mode, a cutscene plays depicting him undergoing a sort of Power Incontinence, screaming in pain and grasping his head while his ship collapses around him before crashing. Likely due to his technopathic connection to his technology. This also happens in Story Mode; Brainiac's defeat results in his ship being sent hurtling towards the Earth, threatening the billions of shrunken cities onboard.
  • Magic Versus Science: Firmly on the science side. His intros with more magic-based characters have him scoffing at their abilities, such as telling Wonder Woman "no gods can save you", blandly noting to Darkseid that he's defeated gods before, responding to Cheetah's assertion that her magic is beyond him with "NOTHING is beyond me", and telling various magic-based characters that he will collect their magic and/or make them share the knowledge. That said, it's also clear that he doesn't know much about what magic and other mystical things are truly capable of. He claims that Darkseid's power can't so much as touch him, but it demonstrably can do more than that. He overlooked Kahndaq, according to Black Adam, because he didn't know it existed or that the Rock of Eternity was protecting it. And because he didn't collect Kahndaq, Black Adam and Aquaman are able to cripple the shields of his Skullship and allow the World's Finest to board it.
  • The Man Behind the Man:
    • It's revealed that he is the mastermind behind Gorilla Grodd and by extension, the whole Society. In the comics, he's also the mastermind behind both the League of Shadows and the Red Lantern attack on Oa.
    • In turn, the Lords of Order are backing Brainiac, believing that he will "restore order" to Earth. They even warn Doctor Fate from intervening, as doing so would only be the catalyst for something worse on the horizon.
  • Mecha-Mooks: His Betas. As shown in Injustice #64, they're strong enough to kill Red Lanterns.
  • Mind Manipulation: He can mind control people with his technology, which he abuses to make Swamp Thing and Firestorm attack Superman after he defeats and captures them. In the Absolute Power ending, Superman uses the same technology to Mind Rape Batman into submission.
  • Multiversal Conqueror: His MO, according to several of his intros, is not restricted to this universe. His Mirror Match intros and those with Sub Zero even have an alternate universe Brainiac saying he's only in the Injustice Universe because he already collected his own.
    • One of the events available in Multiverse Mode is "Overtaken". It's a Boss Level against Earth-1212 Brainiac... who the flavor text states has already conquered 17.6% of the multiverse. "Our" Brainiac is really only getting started by comparison...
  • My Name Is Inigo Montoya: "I. Am. Brainiac."
  • Nerves of Steel: He's apathetic to nearly all of his opponents, whether they be a Physical God, Wizard, or Space Police, considering himself superior to all of them. Considering he's annihilated billions of civilizations and apparently killed gods before, he's not bluffing. It doesn't impress Scarecrow, though.
    Scarecrow: And what terrifies you, Brainiac?
    Brainiac: I. Fear. Nothing.
    Scarecrow: Hmmm... a lapse born of arrogance.
  • New Powers as the Plot Demands: In the Story Mode, he displays a few abilities once and then never again. A notable example is when he somehow creates Grid seemingly from nowhere with Eye Beams shot from a computer monitor, violating the law of conservation of mass in the process. He also seems to achieve Flight in the cutscene where he fights Superman, complete with a unique sound effect, which he can't do in gameplay.
  • No-Sell:
    • Walks off Black Canary's scream like it's an ordinary sound, which is notable because in the prequel comics Black Canary's cry was able to wound even Superman. He also shrugs off a full burst of Supergirl's heat vision, who promptly collapses from the exertion. Additionally, Grodd and Ivy's intros have them saying that their Mind Control doesn't work on him.
    • In Injustice #65, Superboy/Connor Kent unleashes his most powerful heat vision burst in a rage when Brainiac seemingly kills Cassie, discharging directly into Brainiac's face and upper torso. Brainiac simply walks through it, punches Superboy in the face (bloodying him and nearly making him lose consciousness), and tells him in a mildly annoyed tone to cut it out.
  • Not Distracted by the Sexy: Played With. Brainiac is a cold, logical and stoic being who tells in one fight introduction Poison Ivy that her charms do not tempt him because carnal pleasures are beneath him. With that said, he notes Catwoman's sensuous beauty in one of their intros and ends up getting controlled by Poison Ivy in her Arcade Ending and being compelled into capturing all cities in the world in exchange for a kiss.
  • Not So Different: Green Arrow complains in dialogue with Brainiac that all the aliens he meets are despots. Brainiac shoots back that humanity has its own share of despots and they don't need him or Superman to be oppressed. Arrow is forced to concede the point.
  • Not So Stoic: His cold, emotionless facade will sometimes crack: in Story Mode he can't keep a smug smile off his face when he begins collecting Earth's cities, and in his intros he'll occasionally express annoyance, anger, or even (disturbingly) lust. In his intros with Green Lantern and Batman, he almost laughs when the latter two claim they will defeat and capture him.
  • Obviously Evil: Everything about him from his imposing physique to his raspy voice to his creepy and obvious cybernetics screams "evil." And that's not even getting into his gigantic skull-shaped ships or army of robotic minions that look like mutilated corpses. Lampshaded by Black Canary:
    Black Canary: The skull-shaped ship's a bit obvious.
    Brainiac: Fear facilitates collection.
    Black Canary: The tentacles just make it silly.
  • Omnicidal Maniac: Once he has the knowledge from a given planet, he destroys it.
  • Omniscient Morality Licence: Apparently, being a genius is grounds to do whatever you like.
  • Pet the Dog: Takes a genuine interest in Cyborg, to the point where he even wanted him by his side. However, Cyborg is clearly more disgusted by this.
  • Planet Looters: Routine for him. He takes what he wants from a given world, then discards the rest for being superfluous.
  • Pragmatic Villainy: In the ending, he goes bonkers when Superman takes over his ship, fearing that he'll crash it due to not being able to handle it, and destroy Brainiac's collection. Not because Brainiac actually cares about the trillions of people sealed away on it, but because he values the knowledge contained within.
    • As with the above example with Superman, Brainiac knows the Joker will destroy his collection for good due to his Ax-Crazy MO. This is because he sees the Clown Prince of Crime as a cancer that needs to be neutralized.
  • Psychic Powers: Heavily implied to be a product of his Super Intelligence. Grodd comments that after he's seen Brainiac's mind, he's convinced that no one can defeat him, despite his own mind control abilities. One of his round win quotes is also "I know your thoughts", implying a degree of telepathy (which would be consistent with his comics self).
  • Purple Is Powerful: His default outfit includes a lot of purple highlights.
  • "The Reason You Suck" Speech: Gives one to Batman after capturing him and Supergirl in the Story Mode:
    Brainiac: You have failed in every effort to oppose me. You are not exceptional. Merely an ordinary specimen of a primitive species.
  • The Reveal: If you play as Brainiac in the Arcade Mode its revealed that the one you are controlling is Brainiac 5, his heroic descendant from the future and member of the Legion of Superheroes who traveled back in time to stop him.
  • Rogues Gallery Transplant: In the comics, he's often a Justice League enemy just due to his high power and threat level, but he is still very much an iconic Superman foe, his Arch-Enemy and thematic Evil Counterpart. In the Injustice Universe, he's more of a general DCU threat — and hasn't encountered Superman before the events of the game.
  • Rubber-Forehead Aliens: Brainiac is a Coluan, resembling a green humanoid (specifically Jeffrey Combs) with metallic appendages covering his body.
  • Sadistic Choice: Offers this ultimatum to Batman in Chapter 8: surrender Kara or he will destroy Planet Earth. Batman notes that even if they did, Brainiac would still destroy the planet.
  • Sarcasm Mode: In one possible pre-battle intro, Superman tells him that he can't have Earth. A skeptical Brainiac asks if it would fare any better under Supes, which Superman doesn't see for an insult.
  • Science Cannot Comprehend Phlebotinum: It's often brought up in pre-battle intros that Brainiac doesn't understand mystical things on Earth like magic and the Green. Black Adam claims this is why he gave Kahndaq a wide berth, what with it being the site of the Rock of Eternity. Grodd, who has more familiarity with Earth and its mysteries, replies he won't make that error.
  • Secret A.I. Moves: Whenever the AI plays Brainiac on his mothership stage, he'll have access to several giant metallic tentacles that can attack the player. In effect, it turns the battle into one against both him and his ship. Naturally, the player can't use these when they control him.
  • Secondary Color Nemesis: His skin is green and his armor has purple highlights to contrast with the red and blue of Superman.
  • Sesquipedalian Loquaciousness: He talks this way, probably to emphasize his Super Intelligence.
  • Shock and Awe: His tentacles can electrocute opponents. One of his Secret A.I. Moves is also planting a mine that electrifies the floor.
  • Slouch of Villainy: In his mothership, he will stand in the background watching from his throne as the two fighters duke it out if he is not selected by the player.
  • Smug Super: Sees himself as a superior being to all life on Earth. In fact the better part of his intro dialogue consists of him bragging about how he's superior to his opponent. This includes Darkseid and Raiden, who are literally deities.
  • SNK Boss: In Arcade mode due to the above mentioned Secret A.I. Moves, which include attacks that are very hard to dodge and one that does more damage than a player's super move.
  • The Sociopath: All he cares about is knowledge, everything else can burn.
  • Soft-Spoken Sadist: Talks in a calm, almost fatherly voice. It only highlights how evil he really is.
  • Strong as They Need to Be: He's at least as strong as Superman in the main story, but can be defeated by Badass Normal characters like Deadshot in Arcade Mode. Justified in that Arcade Mode endings are explicitly alternate universes, so the alternate universe versions of Brainiac could just be weaker.
  • Suicidal Overconfidence: Invoked on anyone who challenges him. In particular, Brainiac seems more incredulous and disbelieving than anything else in his intros with characters obviously way below his level.
    Captain Cold: Got a problem, Brainiac?
    Brainiac: With your self-delusion? Yes.

    Batman: You've heard of the Phantom Zone?/Green Lantern: The Guardians want you on trial.
    Brainiac: (almost laughing) You mean to imprison me?
  • Super Intelligence: A little, yeah.
  • Super Strength: Goes hand to hand with Superman in the cutscene before his boss fight, and actually seems to have a noticeable edge. His stage transition (which only really makes sense when he does it) is also the most impressive in the game in terms of striking strength displayed- he kicks his opponent straight through the walls of his ship, which are several meters thick and made out of some alien alloy far more durable than any Earth armor (judging by the fact that parts of the ship are capable of restraining Kryptonians, and his own armor is capable of holding up to their blows). This became more notable when Injustice #65 showed that even Superboy/Connor Kent couldn't break the walls of the same ship with his most powerful punches.
  • Technopath: Part of his Secret AI Moveset includes controlling parts of his ship to attack the opponent.
  • Tin Tyrant: He's covered in Powered Armor.
  • Too Powerful to Live: Apart from the fact that he deserves to die, this is the Regime's big contention about wanting to kill him over imprisoning him — he's simply too strong to be contained by Earth technology. Batman's counterpoint is that they need him to restore the lost cities of Earth, but his point is weakened by his inability to name a prison that would be up to the task.
  • Unknown Rival: Both Superman and Supergirl considered him The Dreaded and are terrified of him. Meanwhile, prior to the events of the game, Brainiac had no idea that they even existed, and was busy destroying billions of other populated worlds instead of looking for them. This changed when Regime Superman's war with the Green Lanterns drew his attention, but if that hadn't happened, he probably would have continued laying waste to the multiverse for the rest of his life, ignorant as to their survival.
  • Villain Has a Point:
    • His complaints about how conflictive humans can be are right. As is his comment that Batman's trust in Harley Quinn (who just a few months ago nuked a major city alongside Joker, starting the whole mess) defies logic. His intros with Black Canary also have him calling the latter an idiot for sparing Superman in the prequel comics, as the rogue Superman then went on to conquer the Earth and kill a lot of people ("your weakness condemns thousands"). Black Canary can only respond that good guys don't kill.
    • Green Arrow thinks he's just another wannabe alien Evil Overlord who's Not So Different from Superman or Darkseid, only for him to retort that Earth has its own share of tyrants and they don't need an alien overlord to be oppressed. Arrow is forced to accept the point.
    • In one possible pre-battle intro, Superman tells him that he can't have Earth. A skeptical Brainiac asks if it would fare any better under Supes, which Superman doesn't see for an insult.
  • Villain Respect: While he treats most of the cast with a mixture of contempt and apathy, he holds a surprisingly genuine respect for Cyborg, calling him "the pinnacle of human evolution" for being half-machine. This even extends to some of their intros, where he showers Cyborg with praise and compliments and even offers him the chance to join him. Cyborg begs to differ.
  • Villainous Breakdown: His cold, detached demeanor turns to anger when Superman takes control of his ship.
  • Villainous Crush: Implied towards Catwoman during one intro.
    Brainiac: You are beauty at it's most sensuous.
    Catwoman: Should I be creeped out, or flattered?
    Brainiac: Flattered. It saves your life.
  • Worf Had the Flu: Superman says he was only able to beat Brainiac because the attacks on his fleet by his fellow heroes weakened Brainiac mid-battle.
  • Worthy Opponent: Subverted with Batman and Superman. He's actually pretty disappointed how little of a challenge they are.
    Brainiac: [to Batman] You have failed in every effort to oppose me. You are not exceptional. Merely an ordinary example of a primitive species.
    Brainiac: [to Superman] Earth sapped your potential, Superman... it made you a simple brute.
    • Played straight with Cyborg however, who he wishes to recruit as a protege. Cyborg scoffs at the idea.
    • Double subverted with Darkseid; their clash quotes show that Darkseid considers Brainiac to be this, but Brainiac doesn't share the sentiment. Though Darkseid's ending shows that he saw Brainiac as nothing more than an "errant intellect" when compared to a god's power. The Lord of Apokolips Omega-beams the Coluan to prevent a Kill Steal as he saw Superman as his and his alone to kill.
    Darkseid: Tap your tremendous power!
    Brainiac: It'd be unfair I use all of it on you.
    Darkseid: Together we could crush Superman.
    Brainiac: Earth's history suggests otherwise.
  • You Are Better Than You Think You Are: A villainous example. He says this about Cyborg, feeling that his humanity holds him back from reaching his full potential. And he proves this by incarnating his digital self in the form of Grid. Cyborg thinks otherwise.

    Doctor Fate 
Kent Nelson/Doctor Fate

Species: Human

Voiced by: David Sobolov, Raúl Anaya (Latin-American Spanish dub), Bernd Rumpf (German dub), Philippe Dumond (French), Marco Balbi (Italian), Carlos Campanile (Brazilian dub)
What comes next, mere mortals cannot stop.

Kent Nelson is an ordinary man, but when he puts on the Helm of Fate, he becomes a powerful servants of the Lords of Order and acts to preserve the destiny of the universe. The only problem is that, in the Injustice universe, only a terrible destiny awaits the planet. From the war between Batman and Superman and the impending invasion of Brainiac, Fate only wishes to change what will come, but he is bound to let the atrocities happen so something greater than Earth will be spared.

  • Adaptational Villainy: Most versions of Doctor Fate had Kent and Nabu working in perfect harmony with each other to fight evil, and rarely (if ever) did they come to blows with each other. In this game, however, Nabu mostly overrules Kent and regards enforcing his Lords of Order's definition of order (even at the cost of innocent lives) as more important than fighting evil-doers. A viewpoint that's summed with a Mirror Match intro he has with another Doctor Fate who acts more like his mainstream counterpart.
    Doctor Fate 1: Do you fight for fate?
    Doctor Fate 2: I fight for justice!
    Doctor Fate 1: Your priorities are misordered.
  • Armor-Piercing Response: Doctor Fate gives these out like candy in his battle intros. No-one — Insurgency, Regime, Society or otherwise — is safe from his cutting retorts.
    Dr. Fate: Read my mind, Grodd.
    Gorilla Grodd: ...It cannot be!
    Dr. Fate: Yes. You are doomed to fail.

    Dr. Fate: Fate is no joking matter!
    Harley Quinn: And I ain't no Joker!
    Dr. Fate: Yet there's blood on your hands.
  • Badass Baritone: On top of Power Echoes.
  • Battle in the Center of the Mind: One of his mirror match intros implies one is happening between Kent and Nabu over the Lords' behavior.
    Doctor Fate 1/Kent: The Lords have failed us, Nabu!
    Doctor Fate 2/Nabu: You betray your masters?!
    Doctor Fate 1/Kent: They betrayed humanity.
  • Black Magic: His trait allows him to utilize dark magic, projecting a red aura and making his special moves more damaging.
  • Blue-and-Orange Morality: Nabu only cares for preserving order, rather than actually fighting evil. In the Story Mode, this leads to Doctor Fate betraying the heroes and siding with Brainiac, who Nabu claims will bring true order to Earth and the galaxy.
  • Broken Faceplate: Superman flattens the Helmet of Fate to prevent Nabu from manipulating Kent.
  • Cassandra Truth: Warns that the infighting between Superman and Batman is causing the Lords of Order to give up on humanity, which is why they back Brainiac (because it's implied there's a greater threat coming. Either Darkseid or possibly Nekron). All the same, they don't take his advice and make up.
  • Conscience Makes You Go Back: While allowing the predicted cataclysm to happen is in-line with the flow of history, in the Arcade mode Doctor Fate rebels and works to protect the Earth from destruction, though at the risk of creating an unforeseeable - and potentially worse - alternate timeline. Sadly, the same can't be said of his Story Mode counterpart.
  • Cool Helmet: The Helmet of Fate, a mystical artifact that is both a medium and amplifier to his powers. His various gear options influence the look of it to varying degrees. Unfortunately it's something of an Artifact of Doom as well, with Black Adam noting that those who wear it go mad.
  • Dying as Yourself: Superman destroys the Helmet of Fate when Nabu sides with Brainiac, breaking the hold the Lords of Order have on Kent Nelson's mind. He has just enough time to apologize for his actions before Brainiac suddenly kills him.
  • Earn Your Happy Ending: In his Arcade ending, he relinquishes the Helmet of Fate and is reunited with his resurrected wife, Inza.
  • Esoteric Motifs: An Ankh, which he manages to weaponize.
  • Justice Will Prevail: Well, not justice per sé...
    Doctor Fate: Order will be enforced/restored.
  • Kung-Fu Wizard: As expected of a wizard in a fighting game.
  • Me's a Crowd: His super move transports his opponent to the Tower of Fate to be beat on by several previous Doctor Fates.
  • Not So Above It All: Despite his tendency to act all serious and mystical in other parts of the game, in one of his battle intros with Bane, he seems barely able to suppress a chuckle when he tells Bane that he can't pull the Helmet of Fate off his head.
  • Not That Kind of Doctor: When Joker tries to rope him into a comedy doctor routine.
    Joker: Or much of a Straight Man.
  • Order Is Not Good: The Lords of Order have ordered Kent to not interfere on Brainiac's invasion because it will restore order to Earth — even though he plans to harvest all valuable contents and destroy what is left.
  • Pet the Dog: He broke the laws of Fate to save Dinah in the first place and when he senses Brainiac's invasion coming in Chapter 3, he attempts to take both her and Ollie out of this dimension for their safety. By force if necessary.
  • Poor Communication Kills: In the prequel comic, he visits Black Canary and Green Arrow. He starts his speech by telling them that Black Canary should have died. It takes a hole in his hand later for him to finally point out that he was speaking in the past tense.
    Doctor Fate: I am not here to harm you. I am here with news, and an offer.
    Black Canary: Well, why not open with that?
    Green Arrow: Seriously, you'd have one less hole in you if you just tried speaking like a human person.
  • Power Echoes: On top of having a Badass Baritone.
  • Split Personality: Between the mostly compassionate Kent Nelson who sided with Batman during his fight against the Regime and the far more ruthless Nabu who fights the good guys to ensure Brainiac's success.
  • The Stoic: Is pretty emotionless in nearly every intro and the story, which is a source of ire and mockery to the other members of the cast.
  • To Be Lawful or Good: The Lords of Order declare that Brainiac is an agent of order that will restore balance and Kent must not intervene in his invasion, which troubles him greatly. What side he ultimately picks depends: In the Story Mode, he sides with the Law and tries to stop Superman and Batman from saving the world from Brainiac. In his Arcade Mode, he obviously decides to be Good and confronts Brainiac himself, defying the Lords' will.

    The Joker 
Jack Napier/The Joker

Species: Human

Voiced by: Richard Epcar, José Antonio Macías (Latin American Spanish dub), Bodo Wolf (German dub), Stéphane Ronchewski (French dub), Riccardo Peroni (Italian), Marcio Simões (Brazilian dub)

The Joker was killed by Superman before the events of the first game, but has inexplicably returned to the Injustice universe to wreak havoc once more. Whether he returned from the dead, hails from an alternate universe, or is merely a hallucination is left unanswered, but he plans to continue to plunge the world into chaos just as before.

In combat, Joker uses his revolver, knife, crowbar, joy buzzer, laughing gas canisters and a flag gun that actually fires the flag to torture his opponents. His trait allows him to get faster the more he laughs.

  • 0% Approval Rating: Years after his death, he's still in this territory. Clearly nobody, not even villains like Gorilla Grodd and Brainiac, hold a good opinion of him. The fact that he's indirectly responsible for the mess in the Injustice-verse doesn't help either. Heck, even his ex-moll Harley has come to despise him. Darkseid, the ultimate Big Bad of the whole DC universe, sees him as what he is as well.
  • Adaptational Attractiveness: Compared to his Gonkish appearance in the first game in-line with his tendency to be drawn with rather exaggerated features in most media, he has a more human looking face that verges on being good-looking here, Body Horror and questionable fashion sense aside.
  • Adaptational Jerkass: The mainstream Joker was purely evil from the start, but his cruelty is bumped up a notch to overshadow his theatricality, making him even harder to root for.
  • Amazing Technicolor Population: He's as bleach white as always.
  • Ambiguously Human: Though he's Dead All Along in story mode, how he came back alive in non-story fights is unknown as he'll roll along what his opponent thinks is true, just like his Multiple-Choice Past. Plus, the fact that he can fire his "Bang!" Flag Gun through his ear and take it out the other, aside from his bullet-ridden body, all show something's off about him.
  • Ambiguous Situation: It is left intentionally vague whether this Joker is the Injustice Joker coming Back from the Dead through either Shinnok or the Lord of the Unliving Nekron, the mainstream Joker making his way into the Injustice universe, or merely a Fear Toxin-induced hallucination. His interactions with the cast provides evidence of all three, though his appearance in the story is as Harley's fear gas hallucination.
  • Appropriated Appellation: One intro between him and Dr. Fate has the latter calling him an "Agent of Chaos". Joker quips that he'll have to add that to his resume.
  • Arch-Enemy:
    • The Joker of the Injustice Earth set up the nuke that obliterated Metropolis, and used Scarecrow's fear gas to trick Superman into killing Lois Lane (which was the trigger for the nuke). Supes' Start of Darkness was set in motion after he killed the Joker in his heartbroken fury, and his legacy is still felt and addressed in the story despite being long dead.
    • He also counts as one for Harley due to her Character Development, which is emphasized by his sole appearance in the story as a Fear Toxin hallucination and how she's permanently done with his insanity.
    • Intros often bring up his eternal rivalry with the Bat-family as well, although Batman is so sick of him now that he refuses to indulge him anymore.
  • Arson, Murder, and Jaywalking: All three are listed among his many crimes, "jaywalking" being at the very end.
  • Art Evolution: Compared to the first game, Joker has more realistic facial features, most prominently a less pronounced chin.
  • Attention Whore: Scarecrow subtly accuses him of being one, asking if he works alone because he's afraid of being upstaged.
  • Ax-Crazy: A shtick of his. Doctor Fate even calls him an "Agent of Chaos".
  • Back from the Dead:
  • Badass Biker: Parodied with how his Endgame gear set and other gear pieces have him wear a 50's style biker uniform.
  • The Bad Guy Wins: From his perspective. He may have died, but he still acts as the Greater-Scope Villain to Superman even years later, even rubbing it in his face:
    Joker: Don't you see, Superman? I won!
    Superman: You died. How's that winning?
    Joker: I made you lose control!
  • "Bang!" Flag Gun: He can use the flag as an explosive spear, and his mid-fight pose has him shoot the flag through his ear, taking it out the other.
  • Beware the Silly Ones: He may look like a stereotypical clown, but don't be fooled by his appearance.
  • Black Comedy: Deconstructed. He thinks horrible things should be Played for Laughs, but no one finds his jokes funny, especially when he's the one truly responsible for the chaos in the Injustice-verse.
  • Body Horror: Without a shirt, it can be observed that the Joker is full of bullet holes across his torso and arms, complete with blood pouring out of them.
  • But for Me, It Was Tuesday: As is with him in most DCU media, the Joker doesn't remember the names or keep a count of the countless victims he's killed, tormented or maimed throughout his career. Lampshaded in one of his intros with Cyborg.
    Joker: And what's your beef?
    Cyborg: You killed people I loved.
    Joker: Gonna have to be more specific.
  • Cold-Blooded Torture: Does this to his opponent in his Super move.
  • Composite Character: Still has the poses and voice of Injustice I Joker, but he now wears his classic purple trenchcoat (with the matching hat an optional gear choice) and his lack of shirt in many gear options calls to mind Jared Leto's Joker.
  • Cool Mask: Parodied in that he gets a Batman mask in some gear options, but it is rather crude looking with a jagged mouth cut out and floppy ears.
  • The Corrupter: To both Superman and Harley, albeit in different ways.
    • Even from beyond the grave, he still haunts Superman. Big Blue, while not a saint himself post-Metropolis, can't fathom that the Joker's only goals were to prove his ideals wrong and to spread wanton chaos whether or not he survived. Doctor Fate notes that the Monster Clown's scheme worked so well that it's causing the Lords of Order to give up on humanity itself, hence their backing Brainiac, and Fate even warns that they'll back an even bigger threat should the infighting between Batman and Superman keep on going.
    • He once corrupted Harley, to explain her Heel–Face Turn. She is absolutely done with him, and gets riled whenever someone rubs her past association with Mistah J in her face.
  • Creepy High-Pitched Voice: Courtesy of his voice actor. He has a high-pitched voice to contrast Batman's Badass Baritone.
  • Crowbar Combatant: Like the first game, Joker has several moves involving beating his opponent with a crowbar, including a new move where he throws it.
  • Dead All Along: Joker, as he appears in the Story Mode, is still dead. His only appearance is actually just a Fear Toxin-induced hallucination suffered by Harley in Chapter 2.
  • Deconstructed Character Archetype: This Joker deconstructs the Monster Clown trope. While known to be Laughably Evil, nobody finds his jokes funny, especially when they're full of references to spreading anarchy or nihilism, on top of being responsible for the chaos in the Injustice-verse just For the Evulz. The sheer horror of his misdeeds prompts revulsion even in other villains who have more abstract goals like world conquest. His rants about others being Not So Different from him also show how insane he truly is.
  • Demoted to Extra: As he's long dead, he only appears as a Fear Toxin-induced hallucination to Harley in story mode.
  • Domestic Abuse: Catwoman calls him "Harley's abusive ex" in an intro. Harley herself tells another Harley that he was "demented and abusive."
  • The Dreaded: He's this to everyone, including villains such as Brainiac and Gorilla Grodd, even from beyond the grave.
  • Electric Joybuzzer: A favorite gadget of his, he uses one as a counter move.
  • Electric Torture: Straps his opponent to an electric chair as part of his Super.
  • Evil Cannot Comprehend Good: He thinks the other characters are Not So Different from him and likes to proclaim the futility of their motives in his Straw Nihilist mindset, but they consider it nonsense and even call him out on his insanity.
  • Evil Has a Bad Sense of Humor: Some of the things he says are funny on purpose, but just as often they're only really funny to him.
  • Evil Laugh: Wouldn't be the Joker without it. In fact, his one-line intro has him performing one while slowly turning around to face his opponent. His revised trait even revolves around him laughing to increase his speed. He cackles like an Ax-Crazy homicidal maniac while zapping his opponent on an electric chair as part of his Super. His arcade ending finally has him do one while he stitches the freed alien cities from Brainiac's collection into a chaotic mess and gleefully watches the resulting carnage from a distance.
  • Fan Disservice: His default outfit has an open jacket that reveals his torso, which is riddled with bleeding bullet holes.
  • Faux Affably Evil: What do you expect from a Monster Clown who's responsible for the misery within the Injustice-verse, yet maintains a twisted sense of humor?
  • Fingerless Gloves: Wears punk-inspired studded fingerless gloves in some gear pieces.
  • Five-Finger Fillet: Offers this game to some of his opponents, though they're less than thrilled.
  • For the Evulz: Deconstructed. Aside from causing Superman's downfall and the subsequent chain of events just for evil, the sheer horror of his misdeeds prompts revulsion even in other villains. His MO to prove the true "ugliness" of society and think others are Not So Different from him reveals how psychotic he truly is.
  • Freudian Excuse: Discussed by Atrocitus, wondering what caused Joker to become a nihilist. While the exact reason is unknown, Joker looked surprised when Atrocitus mentioned it.
  • The Friend Nobody Likes: Friend is really pushing it, but the fact that he kills and destroys for fun repulses compared to his fellow villains who have more abstract goals like conquest and power, and his nuking of Metropolis is treated as Beyond Redemption, crossing a line that he should not have crossed. Even the likes of Darkseid, Brainiac, and Gorilla Grodd all sneer at him for his heinousness.
  • Greater-Scope Villain: Even though Brainiac was responsible for blowing up Krypton, the Joker is the root cause of Superman's Face–Heel Turn, and his posthumous legacy still haunts everyone. He even rubs this status in Superman's and Batman's faces.
  • Handwraps of Awesome: Some of his gear options give him hand wraps made out of belts.
  • Hate Sink: The Joker has no redeeming qualities whatsoever, and he is indirectly responsible for everything wrong with the Injustice universe by virtue of causing Superman's downfall. Thus the entire cast hates him and no one is happy to see him back, not even Harley. His one usual trait that makes him likeable — being funny — is used to draw attention to how awful he is, cracking jokes about mass murder and mutilation and mocking his opponents' personal pain.
  • Hearing Voices: Some of his clash quotes have him asking his opponent if they're hallucinating.
    Joker: Voices in your head too?
  • Hellbent For Leather: His default longboat is made of leather and some of his gear options give him punk-style gloves and pants. His new gear in the Legendary Edition update gives him a biker-esque leather jacket.
  • Hidden Depths: Atrocitus thinks something specific drove Joker to nihilism. Being the Trope Codifier for Multiple-Choice Past, Joker sounded genuinely surprised when Atrocitus brought it up in one of their banters.
  • The Hyena: A shtick of his — he laughs at the misery of others. Being the DCU's resident Nietzsche Wannabe Monster Clown, he sadistically cackles at everything, especially death, destruction, and despair. He's even known to laugh maniacally when he's the one on the receiving end, especially when Superman killed him in the first game.
  • Improbable Weapon User: One of his knives appears to be fashioned out of a pen.
  • Ink-Suit Actor: Bears a resemblance to Richard Epcar, his voice actor.
  • Insult Backfire: His clash dialogue and intros are just full of this.
    Swamp Thing: You sick, unnatural clown!
    The Joker: Thank you!

    Poison Ivy: I'll spit on your grave!
    The Joker: It could use a polish.
  • Insult to Rocks: He's so vicious and cruel that Grodd, who usually hates humans, calls him a disgrace to his species. Vixen also says that calling him an animal would be an insult to animals.
  • It Amused Me: What do you expect from a sicko who sadistically torments and mocks people at their expense, and leaves the world much worse than before? When said Monster Clown finds it funny to do such things, they clearly have problems. Also, nobody finds his jokes funny, especially when they're full of references to anarchy, causing wanton mayhem, or nihilism.
  • I Was Just Passing Through: His Ladder Ending reveals he hadn't intended to go after Brainiac at first, and only ended up doing so as a distraction. Nevertheless, he beat the (other) bad guy.
  • Joker Immunity: Well, in the story he's dead as a door nail, but for the purposes of any non-story fight he's in, Joker turns up mysteriously alive. He never says exactly how, but in any case, what can you expect from someone who somehow survived constant beatings for 80 years?
    Superman: Why won't you stay dead?!
    Joker: I'll always have extra lives.
  • Knife Nut: Like before, he uses a knife as his primary weapon. The appearance is affected through various gear options.
  • Laughably Evil: Deconstructed — while he's written as capable of cracking hilarious jokes, it's also shown that his evil side far exceeds it, and that it's entirely possible for one aspect of this trope to be so horrific as to almost cancel the other out. His attempts at Black Comedy are used to call attention as to who would find mocking people's misery and tormenting them funny. To him, death is the ultimate punchline, life is a joke, and all ironies are equally silly.
  • Laughing Mad: Cackles a lot when he wins a match, while doing Cold-Blooded Torture on his opponent in his Super, and in his arcade ending.
  • Leaning on the Fourth Wall: Arguably his stock clash quote, "and people think I can't fight", given that this underestimation of him doesn't happen nearly as much in-universe.
  • Lethal Joke Character: Many usually think he's just a buffoonish clown, only to immediately realize why they should be wary of him. Given he's unpredictable and Ax-Crazy, he's one of the most dangerous villains of the DCU, who at times has even upended the likes of Brainiac or Darkseid in terms of villainy.
  • Major Injury Underreaction: His default costume plays up his seemingly-undead nature by showing his bare chest riddled with bleeding bullet holes (though that isn't how he actually died). One of his after-round taunts shows him shooting himself through the head with his "Bang!" Flag Gun, with seemingly no ill effects.
  • Magnum Opus: In-Universe, he considers unleashing Brainiac's collection and the burning chaos it creates in his ending his life's work.
  • Monster Clown: Obviously, but some of his gear options play this up by giving him more dramatic make-up and jester hats. Clearly, nobody finds his jokes funny, especially when they're laden with references to spreading anarchy, Black Comedy, or the pointlessness of life.
  • Multiple-Choice Past: Just like his backstory, he offers different explanations for his Back from the Dead status in dialogue exchanges. From another Earth? A Scarecrow-induced illusion? Resurrected by Nekron or Shinnok? The Lazarus Pits? The Source Wall? The Phantom Zone? Most often, he'll roll with whatever his opponent assumes is true.
  • My Death Is Just the Beginning: Invoked in an interesting way. He's already dead, but he lampshades this by reminding people that his death triggered the Injustice-verse descending into chaos. He would've cackled at the mess he left behind if he were alive.
  • Mythology Gag:
    • His new design leans more towards Jared Leto's Joker, given his long purple coat with no shirt underneath.
    • Dr. Fate calls him an "Agent of Chaos". He likes the sound of that.
      • In his ending, he "watch[es] as the world burns."
    • His epic gear options that give him a crude Batman mask seem to be a nod to an episode of The Batman where he dressed up as Batman.
    • One of his gear pieces is called the Guise of Eric Border, a nod to an alias he used in the Endgame New 52 arc.
    • Several of his shaders and gear pieces are named after story arcs and quotes of his, the most notable being the "One Bad Day" and "Joker's Wild" palettes and "The Last Laugh" headpiece.
  • Never Heard That One Before: Expresses this a quite a few times, such as when Blue Beetle quips that "the joke's on you."
    Joker: Only the svabillionth time I've heard that.
  • Nice Hat: His classic fedora is available as a gear piece, along with a baseball cap, top hat and 50's style biker hat.
  • No Shirt, Long Jacket: Has his purple longcoat as always, but without any undershirt. Some gear options give him a shirt, though.
  • Not So Different: He attempts invoking this on several characters, but they consider it crap and chew him out on his insanity. As usual in most DCU media, the MO for his crimes is to prove their versions of morality wrong.
    Gorilla Grodd: That's not true at all!
    Brainiac: We share no similarities!
    Grid: I am rational. You are mad.
    Darkseid: I'm a god. You're a madman.
    Hellboy: You're crazy. I'm sane. End of story.
    • The only person who barely agrees is Scarecrow. Yet still, Scarecrow despises him.
    Scarecrow: We are both agents of Chaos.
    • Similarly, Cheetah offers what may be some sincere respect. . . or just a veiled threat.
    Cheetah: You took down Superman.
    Joker: And yet I feel empty inside.
    Cheetah: Let the goddess give you purpose.note 
  • Obviously Evil: Does more need to be said about the Joker?
  • Only Known by Their Nickname: As a result of his insanity and Multiple-Choice Past, his real name is unknown to everyone, including himself, though he occasionally goes by the alias Jack, with Jack Napier being the name given in Batman (1989).
  • Pass the Popcorn: His Arcade ending depicts him releasing all of Brainiac's captured cities on Earth, causing the freed aliens to fight for survival, all while he enjoys the scene munching on popcorn and accomplishes his twisted goal of spreading wanton chaos all over the world.
  • Perpetual Smiler: Obviously, a Slasher Smile plastered on his face.
  • Plot-Triggering Death: His death early on in the previous game triggered the chaos surrounding the Injustice-verse, and he even lampshades on it. Dr. Fate even notes that his scheme worked so well that it's slowly causing the Lords of Order to give up on humanity itself.
  • Pop-Cultured Badass:
    Joker: Ehh, never trust anyone under thirty.
  • Posthumous Character: The Injustice-verse Joker was killed by Superman in the first game's prologue. Pre-match dialogue exchanges have the Joker naturally offer a Multiple-Choice Past as to his return, while he only appears once in the game's story mode as a fear toxin-induced hallucination.
  • Psycho Electro: Straps his opponent in an electric chair and sadistically tortures them while cackling in glee after bashing their head with a crowbar. He also uses an Electric Joybuzzer as a counter.
  • Psychopathic Manchild: While his intellect is far from childlike, he uses clown-related gags and laughs like a hyena even when torturing someone in his super move, really throwing his maturity into question.
  • Poison Is Evil: His toxin is incredibly painful and leaves its victims with a ghastly smile when all is said and done.
  • Rummage Sale Reject: Quite a few of his gear options are odd to say the least, which include cargo shorts, baseball equipment and ad-hoc armor pieces hastily strapped on his suit, to name a few.
  • Sadist: Obviously. Part of his super move involves him doing Cold-Blooded Torture on his opponent, all while cackling in glee.
  • Slasher Smile: An ugly grin plastered on his face, and always cackling at everything, even when he uses Cold-Blooded Torture on his opponent in his Super move.
  • Small Role, Big Impact: Even though he had a small role in both games, who can forget his sickening legacy of causing Superman's Face–Heel Turn and the world descending into chaos? It was his ultimate goal after all, as his MO really worked.
  • The Sociopath: Has a distinct Lack of Empathy, is a Sadist of the highest order, relishes in wanton death and destruction, and his greatest joy in life is convincing others that the DCU is a Crapsack World, and its inhabitants are inherently selfish and self-destructive.
  • Straw Nihilist:
    • Lampshaded in his intros with the Flash, the Atom, and Deadshot. Being the DCU's poster child for nihilism, he believes that everything is just a "joke and a demented gag." Having succeeded with Superman, he even tries invoking the Strike Me Down with All of Your Hatred trope again on the other characters. Given the Joker's repeated use of Multiple-Choice Past, Atrocitus even wonders what exactly drove the Monster Clown to this.
    • Deconstructed as well. His repeated rants on the pointlessness of life actually shows how insane he truly is.
  • Strike Me Down with All of Your Hatred: In some of his clash quotes with several characters, he dares them to kill him. Having succeeded with Superman, he's all too happy to see it happen again as part of his nihilistic MO.
    Joker: Here's your chance. Kill me!/Hit me like you mean it, hero.
  • Sure, Let's Go with That: Even he doesn't know how he came Back from the Dead, and will go along with whatever others think is true.
  • There Is No Kill Like Overkill: His super move involves bashing his opponent's head with a crowbar, shocking them in an electric chair, and blowing them up with several sticks of lit dynamite, eerily reminiscent of how he killed Jason Todd.
  • To Create a Playground for Evil: His Arcade ending depicts him release all of Brainiac's captured cities on Earth, causing everyone to fight for survival and accomplishing the Joker's twisted goal of spreading wanton chaos all over the world.
  • Throwing Your Sword Always Works: Aside from using his crowbar as a blunt object, he can now toss it at his opponent.
  • Torture Technician: Per the norm, Joker finds sadistic glee in beating people to death with crowbars, torturing them with electricity and blowing them up with dynamite sticks.
  • Unexplained Recovery:
  • Villain Has a Point:
    • Tells Batman that letting him live caused pretty much everything bad in this continuity to happen, though Batman wouldn't admit it.
    • During a clash with Wonder Woman, he mockingly tells her that she'll "never be Lois", and he isn't too far off, as long as Superman continues to grieve Lois, Wonder Woman will likely never be able get him to have an intimate relationship with her.
    • "Good" isn't the right word exactly for the fallen Superman, but this is otherwise in effect when he is confused by the Joker claiming that he won in an intro, wondering how getting yourself killed counts as a win. What Superman doesn't get is that it was enough of a victory for Joker to make him lose control, his own survival was utterly secondary to proving Superman's ideals and morality wrong. Joker even rubs it in his face.
  • Villainous Crush: He displays this towards certain female characters like Black Canary, Power Girl, Poison Ivy and Supergirl. They are less than impressed.
    Joker: As my new moll, you'll do nicely.
    Black Canary: In your dreams, clown.
    Joker: Me thinks the canary doth protests too much.
  • Villainous Legacy: Though he's Dead All Along in the game and only appears as a Fear Toxin-induced hallucination to Harley in chapter 2, his role of causing Superman's Start of Darkness in the previous game has not only made enemies in Batman and Superman, it also led to the collapse of everything good in the Injustice-verse. He would've been cackling in glee at the chaos if he were alive.
  • Was It Really Worth It?: In some intros, He actually admits he "somehow feels empty" when his opponent brings up what he did to Superman, implying he didn't get the satisfaction he thought he'd get from what he did.
  • While Rome Burns: His Arcade Ending. After killing Brainiac, he releases the trapped alien cities from all over the universe and stitches them together into one chaotic mess. As the masses kill each other in the most sickening ways, he stands back munching his popcorn and watches the world burn from a distance, while cackling like a maniac.
  • Wicked Cultured:
    Joker: O Captain! My Captain!
    Captain Cold: Whitman? Seriously?
    Joker: A little culture wouldn't kill you.
  • You Monster!: A lot of what the heroes (and even the villains) say to him is some variation of this; a lot of the rest is variations of You're Insane!. Sadly, he's prone to being pleased by such remarks instead.

    Swamp Thing 
Alec Holland/Swamp Thing

Species: Swamp monster

Voiced by: Fred Tatasciore, Octavio Rojas (Latin American Spanish dub), Thomas Rauscher (German dub), Antoine Tomé (French), Stefano Albertini (Italian), Mauro Castro (Brazilian dub)
I guard the green, the plant life of Earth.

A living collection of plant matter that protects 'the Green,' plant life, from his home in Slaughter Swamp. He cares little for the wars of humanity and only allies with them when fighting a threat to the Green.

With heavy emphasis on command throws and ground combat, Swamp Thing can reach across the screen by turning his hands into vines, copy himself to combo enemies, and sprout branches to surprise airborne enemies.

  • Adaptational Wimp: Swamp Thing is one of the most powerful beings in DC — a planet buster who's considered in the same tier as Darkseid, and is one of the handful of DC characters confirmed the be more powerful than Superman. His Injustice counterpart on the other hand gets beaten by Harley Quinn in his introductory appearance. Later, he shows up as a Brainwashed and Crazy goon who can get tossed around by Batman. Safe to say, the comics version of the character can do a whole lot more.
  • Anthropomorphic Personification: Of plant life.
  • Badass Baritone: His voice is deep, guttural and intimidating.
  • Brainwashed and Crazy: Brainiac seizes control of the Green and turns Swamp Thing to his cause. He only returns to his senses after being defeated by Batman or Superman.
  • Complete Immortality: Basically. As the avatar of the Green Swamp Thing can only be killed by destroying all plant matter in the universe.
  • Comically Serious: His no nonsense attitude leads to the humor in his dialogue with such remarks as referencing his head being shot off.
  • Cool Mask: Wears more than few as part of gear options.
  • Deadpan Snarker: Harley Quinn is not amused.
    Harley Quinn: Why do I always get the big guys?
    Swamp Thing: Because you have a big mouth.
    Harley Quinn: Leave the humor to me, pal.
  • Does Not Like Shoes: Much like Atrocitus, Swamp Thing is portrayed as a hulking, organic armored brute, with large, bare feet, throughout the game. Some of his attacks can turn his entire arms and legs into thickets of branches or tree trunks, but revert to their natural state afterwards, leaving him barefoot.
  • Elemental Powers: Can control anything plant related.
  • Everyone Has Standards: Doesn't care for humankind unless they're directly interacting with the Green in some way. However, he makes it clear that he doesn't believe Poison Ivy's claims that her actions are to the betterment of the Green, and he will oppose her if she forces his hand. He even considers Gorilla Grodd to be far worse then mankind.
  • Eye-Obscuring Hat: Some of his masks cover his eyes.
  • Fertile Feet: His character power Abigail's Garden has him leaving behind flowers as he walks, his opponent being unable to dash or jump while inside it.
  • Gaia's Vengeance: In his Arcade ending, he gets tired of humanity's constant fights and covers entire cities with plant life, sending the message that nature will take care of itself.
  • Good Counterpart: To Poison Ivy. He is mostly content with protecting the Green and only joins forces with superheroes by principle.
    Raiden: Will you aid in this realm's protection?
    Swamp Thing: Humanity's problems are NOT mine.
    Raiden: We must fight together, or you will die alone.
  • Green Thumb: Undisputed master of it; the Swamp Thing can control any plant life due to his mystical connection to "the Green." This lets him turn his hand into a tree, spawn a vine from the ground to swing him into the air, and create a second Swamp Thing from the ground.
  • Growing Wings: His victory pose has him sprout wings made of plant matter and fly up as a forest grows around the battlefield. A legendary gear piece allows him to air dash with them.
  • Happily Married: Judging by the name of his character power, Abigail's Garden, he has his comic counterpart's relationship with his wife-in-everything-but-law Abigail Arcane/Cable.
  • Heel–Face Turn: He appears to have abandoned the Regime since the comics and returned to being a Heroic Neutral guardian of nature.
  • Heroic Neutral: His stance in the story. His duty is to the Green, but he will ally with the heroes if it means protecting nature.
    • During a rapport with Vixen, Swamp Thing emphasized the "neutral" aspect by saying that "good is nothing to the Green".
  • Horned Humanoid: Most of his head gear pieces give him horns of varying shapes and sizes.
  • I Am the Noun: In a clash quote with Cheetah.
    Cheetah: Too wild for you?
    Swamp Thing: I am the wild.
  • Jurisdiction Friction: Of supernatural kind. Most of the pre-combat dialogues between him and Fate is some sort of conflict of interests between higher forces they serve.
  • Me's a Crowd: He can form a second Thing to tag-team an opponent.
  • Not Distracted by the Sexy: States to Poison Ivy and Stafire that he sees through their beauty to what lies beneath (rot in Ivy's case, a hot temper in Starfire's). This is unsurprising, as Swamp Thing is both Happily Married and doesn't possess a human sex drive anyway.
  • Plant Person: The Swamp Thing is essentially a sentient patch of swamp grass that took the form of a man in order to defend other plant life.
  • Sickening "Crunch!": His supermove is do drag the opponent underground, break him with gigantic plant fists before sickeningly breaking their back atop a pointed rock.
  • Shut Up, Hannibal!: Can deliver pretty good one to Doctor Fate during their clashes
    Doctor Fate: Order will prevail! | Submit to order!
    Swamp Thing: Yes! The natural order!
  • That Man Is Dead: In one intro dialogue, Canary refers to him as "Alec". He responds that "Alec Holland is no more".
    • Assuming he shares his comic book roots he is absolutely correct; Swamp Thing is a separate entity with Alec Holland's memories who just thought he was Alec for a while. The real Alec Holland is long dead.
  • "The Reason You Suck" Speech: Downplayed, but when he goes into battle against Poison Ivy, some of his opening banter variants personally attack her.
    • In one sequence, he notes that she claims to serve the Green, and then asks why, if that's the case, she treats the plants she claims to protect as her slaves.
    • In another sequence, he claims to see through her beauty, and that what's behind it is "rotted, withered roots".
  • You Will Not Evade Me: He can grab his opponent from a long range distance by turning his arm into two vines that fetter his opponents from across the stage.

    Battle Simulator Brainiac 
Querl Dox/Brainiac 5

Species: Coluan

Voiced by: Liam O'Brien, Octavio Rojas (Latin American Spanish dub)

Wonder why Brainiac fights himself at the end of Battle Simulator? Well, if you're okay with spoiling Brainiac's arcade ending, read about the rest of this character sheet.


Good? Okay, so in Battle Simulator, it turns out the playable Brainiac is really a disguise for Brainiac 5, a heroic descendant of, you guessed it, Brainiac. He's returned to defeat his ancestor to clear the name of his species and undo his many crimes.

  • Canon Character All Along: His appearance as the original Brainiac was merely a disguise for his true heroic identity.
  • Catchphrase: The last line of his ending is "Long live the Legion," firmly establishing that this character is the same one that starred in the Legion of Super-Heroes comic book.
  • Good All Along: Thought you were playing the bad guy? Guess again!
  • I Did What I Had to Do: He gets reprimanded by the Legion of Super-Heroes for "borrowing" a time portal to travel to the past, but he tells them that he did what he must for his people's sake and that he's always on the Legion's side.
