In the Batman Multiverse ending of Injustice 2, Bruce refers to Superman with his Kryptonian name, "Kal" rather than his given name, "Clark" because he no longer views him as the man he once was.
The Regimes hair colors actually have some symbolism behind them. As while Superman, Wonder Woman, Black Adam, Cyborg (before having been shaved bald) and Robin have black hair, symbolizing black-heartedness, as they are malevolent tyrants who live above humanity. Supergirl, on the other hand, is the only one to have blonde hair, symbolizing golden-heartedness, as shes the only member of the Regime to want to live amongst humanity.
During the Absolute Power ending, Batman tries to have Superman kill him by invoking a Strike Me Down with All of Your Hatred on the Fallen Hero. The last time something like this happened, Superman killed the Joker and Lex Luthor after both of them goaded Superman into killing them. After realizing how badly both deaths ended for himself (As Joker managed to completely corrupt Superman and Luthor permanently tarnishing Supermans reputation), he decides to spare Bruce, because he knows that killing someone who is as well-known as Joker and Luthor would come back to bite him in the ass.
During the first chapter, Robin was blasted away by Cyborgs Arm Cannon and would only recover after Batman defeats the latter. Afterwards, Batman doesn't even bother to ask him if hes alright, showing how much of a Knight In Sour Armor he is. However, Batman does ask Kara if she was alright after banishing her cousin Kal to the Phantom Zone. How is this relevant? It exemplifies Batmans character development, where he Took a Level in Idealism.
Almost all of the alternate skins are actually their characters from alternate universes, which explains why characters like John Stewart and Bizarro have an Unexplained Recovery. John even tells Mari, "I'm still the same John you knew" which veers into Tear Jerker when Mari tells John she hasn't heard from him in a long time; "her" John is dead, and this John just arrived from another Earth.
This promotional artwork◊, featured as the cover for the game's Ultimate Edition, shows Batman, Superman, and Supergirl's outfits adorned with glowing accents. The colors of each character's accents are the same as the Lantern Corps they would possibly be part of. Batman has green accents, and the Green Lantern represents Willpower, with Batman doing everything he can to keep the world safe, both from Superman's Regime and Brainiac's invasion. Meanwhile, Superman has yellow accents, and the Yellow Lantern represents Fear, which Superman has inspired in the world after his Regime sought peace through any means necessary. Finally, Supergirl's accents are blue, and the Blue Lantern represents Hope, as the House of El is meant to; Supergirl firmly believes that she and her cousin are supposed to be Hope Bringers as its only remaining members. Even though Superman has long abandoned his idealism, Supergirl still believes in being a symbol of hope for the people of earth.
Additionally, Superman in the first Injustice comic was for a time a Yellow Lantern during the Green/Yellow Lantern conflict.
Additionally, what colors make up green? Blue and yellow, the colors of hope and fear, which is exactly how the current Batman operates.
Also? The green could also represent Kryptonite, which makes sense, as Batman uses a green-highlighted suit during the final battle with Superman. Having a Kryptonite-infused uniform would make sense when fighting Kryptonians.
How does this sequel take place in spite of Telos destroying an Injustice world? Well, just remember Owlman's theory from the Crisis on Two Earths animated movie. In the movie, Owlman states that his choices never mattered as there are other universes that did what he didn't do. So, the universe destroyed by Telos may have been the original or an offshoot and the Injustice 2 universe, while possibly just another offshoot, never had Telos arrive.
Why does the Scarecrow look different from his stage appearance in Injustice 1? Because it's the alternate universe version of him! If you read the Injustice comics, you notice that in the alternate universe incarnation is similar to the playable Scarecrow in Injustice 2, because it's the same character.
Also, why does this Scarecrow look more supernatural than the usual? Because in the comics, he was killed or at least seriously injured by the alternate Joker. During the time between the two games, he was somehow resurrected and given stronger powers. Which could explain why he is voiced by Robert Englund.
Or maybe he is just farsighted and has hidden dozens of gas toxins everywhere so he could use them when he needs them. Or maybe it could be both and you had to fight a real humanoid abomination who uses fear toxins to make the situation even worse.
Jossed, it's neither. He's a hallucination. In fact, one combat move has the hallucination and the mysterious doctor working together to pull a character apart.
How does Scarecrow know so many personal details about the characters? Easy, he doesn't. That's the fear gas talking in the other characters' heads.
Why do the events of the Arkham riot flashback differ from the year one comic they happened in? This game has an increased focus on the Multiverse concept, exemplified by the gameplay mechanic of the same name. So this game is technically a similar but alternate universe from the original comics; this could also explain the differences in Joker's murder scene from the first game and the comic.
DC's Convergence event had a domed city that was heavily implied to be from the original Injustice: Gods Among Us game. That city (and possibly that universe) was destroyed by Telos, so Injustice 2 taking place in a different universe is highly likely.
How does the Sphinx keep losing its nose, again and again, potentially just "minutes" apart? Due to time travel, The Flash might actually be hitting it far further apart historically, with months or years in between his appearances for repairs to happen. Plus, assuming he does this regularly enough in combat, this could be why the Sphinx is noseless to this day; either he smashed it at some point too late historically for the Egyptians to fix it, or they simply stopped trying to fix it due to the frequency of damages over the years.
Another similar possibility: the Earth used as the Battle Simulator in Multiverse mode is stated to be in a Stable Time Loop. Maybe Flash is travelling to that Earth when he uses his supermove, and because of it being in a time loop, the nose is always still there whenever he uses this attack.
There's a green gas every time The Joker enters the battle, and it appears often during the fight. It's not Smilex — it's Scarecrow's fear gas. Joker is just another hallucination.
Confirmed in story mode: Harley fights against a hallucination of the Joker brought on by the fear toxin. Outside of story mode, his situation remains ambiguous.
Supergirl's supermove is noticeably more impressive than almost any other character's, even characters who are in the same power tier as her. Aside from Rule of Cool, there is a reason for this. Think of what happened to her immediately before the story began: she watched Brainiac destroy her world, and then woke from stasis as one of the most powerful beings in the universe. In other words, Kara has very little control (at least compared to the likes of Superman, Black Adam, or Wonder Woman), and a whole lot of painful emotions. So when she lets loose, as in her supermove, she gives it everything. She very well may not be able to do it any other way. Or she just hasn't truly learned she lives in a world made of cardboard yet.
Many people have wondered why Brother Eye, despite eventually becoming a sentient supervillain in the comics, is a big, dumb, and harmless computer console here. Well, in the comics, Brother Eye was originally just exactly that-but here, Batman programmed him not to monitor metahumans, but as an early warning system to replace the Watchtower. He wasn't actually being paranoid about his team members (and even if he was, he had perfectly valid reasons to not want to be burned again), and one of the first things he does after getting his pet project online is to call in his allies and reveal what he's done so that everyone is on the same page. Quite simply, Brother Eye is starting not from the position of "metahumans are not trustworthy" but "metahumans need my help"-Batman never encoded the failsafe protocols that caused Brother Eye to view metahumans as targets, nor did Maxwell Lord encode the King is Dead protocol that would eventually order Brother Eye to become self-aware given how he could no longer fulfil his hacked protocol of "serve Maxwell Lord." Quite simply, Brother Eye is a completely different machine than he is in the DC canon universe. If he does turn evil, it will be due to completely different reasons than in canon-not because Brainiac hacked him to serve as a listening post.
The Mirror Match combat makes sense when you realize the barriers between the multiverse are breaking down. Reverse Flash mentions it in the story itself, while several characters like Jay Garrick and Power Girl note that something is wrong with time and space. This is also the justification of the Multiverse single and multiplayer modes.
In the first game, Bane is bigger, bulkier, and considerably more brutish, while here he is relatively smaller but considerably more eloquent and intelligent in his mannerisms. This makes sense if you consider his venom; the more he uses, the stronger and dumber he becomes. This doubly makes sense when you consider his role in both games; in Gods Among Us, he is with the Regime, which benefits far more if he is more powerful but less likely to think up a scheme and betray them, so they would heavily increase his dosage; here in 2, though, he is part of Grodd's Society, which already has sheer muscle made up by Grodd and Cheetah's super strength, and so he is better off using less and keeping his intelligence at its peak.
It can also be inferred that, now that he is no longer in the fallen, world-dominating Regime, but instead part of the smaller Society, he doesn't have as easy access to venom as he did in Injustice 1, so he's making do with what he has.
Brainaic's ending reveals the Legion to exist in the future, but the dialogue hints that neither Superman nor Batman were aware of them before this. Given what they'd know, it explains a very good reason why their first and perhaps most important role in canon, mentoring the young Superboy, didn't happen. Given how Superman would later act, they had a good reason to not do this. Heck, their absence from this role might have been a factor in his later actions just as much as the previous game's fridge page noted the difference that Luthor not being evil likely had on his mental state. Without their interactions Superman never was shown that good old fashioned heroics were what would be remembered, and that he'd have to do better with his legacy.
Sub-Zero and Raiden's inclusion also makes sense when one remembers the characters they were counterparts to in Mortal Kombat vs. DC Universe with Raiden being Superman's counterpart (the defacto leader and most powerful member of the good guys) and Sub-Zero being Batman's (the loners of the group that also had their own rebellious sidekicks). Is it any wonder that in the Fighter Pack 2 trailer, Sub-Zero is the one being attacked by Raiden mirroring Superman and Batman's rivalry in this series?
It makes sense for the version of The Atom in the game to be Ryan Choi instead of Ray Palmer when you consider the fact that the Firestorm in this game is Jason Rusch instead of Ronnie Raymond and Blue Beatle Jaime Reyes instead of Ted Kord (or even Dan Garrett).
Superman and the Regime seem bent on blaming Batman for Murder by Inaction with him being unwilling to kill the Joker to stop his crimes, which Batman doesn't buy into. But one can argue that Batman is right to not blame himself for the Joker's killings. To clarify, most incarnations of Batman show him to deeply respect the law. Heck, the Diniverse Batman outright states one reason he doesn't kill is that death sentences for the courts to decide, not him. One can argue that Joker being thrown in Arkham Asylum is the result of Gotham's judges and juries deciding he should rehabilitate instead of sentenced to death or sent to a more secure prison. So in truth his crime that led to the events of the Injustice games is actually the result of a fewtoo manyincompetent courtroom decisions.
Batman is unable to respond when Damian asks whether he would have killed Joker if he'd killed Damian and nuked Gotham, which makes even more sense when you think about A Death in the Family, in which Batman did indeed try to kill the Joker for murdering his son. It also involved Superman trying to talk him out of it, which may explain Batman's attempts to do the same — and due to different circumstances and outcomes, why his attempts fail.
Damian's constant exhortations that Nightwing's death was an accidental fall on deaf ears, even though he's telling the truth. Why does no one believe him? It's possible that it's because he joined the Regime, but it's even more likely that he nearly fell into a trap that Batman has been keenly aware of from the beginning and has no doubt considered throughout his career—the moment you deliberately choose to kill, every single death that is remotely your fault comes under suspicion. Because of Damian's willingness to kill in the past, the mere possibility that Nightwing's death was deliberate now exists, and permanently colors other characters' opinions of him.
Each Turtle in their Gameplay Trailer has very fitting opponents to showcase their skills on:
Michaelangelo vs Black Manta - Mikey has always been known to annoy even the craziest of villains in their world, no matter how stoic they are. It makes sense that a deranged killer like Black Manta is who Mikey is pitted against. Bonus points for Manta ALMOST resembling Shredder for being armoured, sharp weapon wielding killers and leaders of their own assassin group.
Donatello vs Brainiac - This one's a no brainer. They're both non-human, green-skinned tech geniuses but on opposite sides of the line. Also, Donnie had to salvage stuff and build his inventions in their sewer home while Brainiac has access to a ton of technology and has the luxury to travel anywhere in the galaxy inside a sleek spaceship.
Leonardo vs Darkseid - The most heroic of the brothers vs the Justice League's nemesis. Ultimate Good vs Ultimate Evil. They both lead their respective groups and care for them genuinely (but on Darkseid's case, it's very rare). They also happen to have the color blue associated with what they wear.
Some may question why Batman doesn't use the dimensional transporter he made in the first game to gather help from the Main Universe heroes in stopping Brainiac, but it's very likely he destroyed the transporter shortly after the event of the first game for a couple of reasons:
First off, he turned down the Main Universe Justice League's offer to aid Earth's recovery from the Regime's tyranny because he wanted the people of Earth to know they're back in charge and that Batman wasn't going to make his own Regime.
Secondly, Batman may have figured there was a risk that any Regime Remnants still at large may try to use the transporter against him by tricking heroes (and possibly even villains) into helping them take Batman out and bolster the Regime's ranks.
Thirdly, even if he didn't destroy the transporter before Brainiac's invasion, Batman may have figured if he brought help from the Main Universe as he did in the previous game, there'd be a risk Brainiac would attack the Batcave, seize the transporter, then use it to invade the Main Universe's Earth along with the Injustice Earth, which best case scenario would make stopping Brainiac even more difficult and worst case scenario would doom two Earths simultaneously.
Actually, he still has the transporter. Brainiac lists inter-dimension travel as one of the tools he disabled when he hacked Brother Eye. Batman doesn't try to use it once Brother Eye is reclaimed because there's simply no time to find the right universe, transport someone over, and explain the situation. Even after Superman's "death", while there's plenty of reason to use it, there's not enough time.
Superman's shock when Robin slit Victor Zsasz's throat may seem hypocritical, but it makes perfect sense. This is just after the Joker's death, and Superman only killed him due to being tricked by him into killing his family. Zsasz, on the other hand, was in jail and summarily executed by Robin for no immediate reason.
Why does Batman still keep to his no killing rule so tightly even after criminals like Joker and Brainiac? Because of Superman's actions after killing Joker. If Joker was just a rare exception given the situation, Batman might have considered it. But instead, it started a tyrannical dictatorship and led to the deaths of far less dangerous criminals and even heroes who partially agreed with Superman. After that Batman would likely try anything else rather than go down that road.
Many fans of Diana were not happy about how easily she fell in with Superman's side. However, the flashback to the first annual explains it by showing how Diana discovered Steve Trevor was a Nazi spy and executed him. Instead of Steve being her guide to the best of humanity, he showed Diana how a regular human could be a murderous traitor and lying to her all this time. Because of that, Diana's view of "Man's World" was automatically darkened. Thus, it would be all too easy for this Diana to decide Superman is right in his attempts to "save" a species she finds so corrupt.
The Power Armor Batman wears to fight Superman at the end has green glowing Tron Lines, indicating it has Kryptonite or Kryptonite radiation emitters, useful for fighting Kryptonians, obviously. Yet this is a specific Shader in Batman's customization menu; if you get the parts that represent this armour but use his standard (Gotham Knight) Shader, the Tron Lines are light blue. While Kryptonite's colors and effects have varied widely in the various continuities, since Smallville Blue Kryptonite has often been able to nullify Kryptonian abilities as long as they are exposed to it (not permanently remove them, like Gold Kryptonite). Essentially, a Blue Kryptonite Power Armor would be a perfect nonlethal anti-Kryptonian weapon, while a Green Kryptonite Power Armor can kill a Kryptonian. Still very helpful against threats like Superman, but still keeping with Batman's One Rule. It also shows that the final chapter of Injustice 2 has Batman well and truly past the Godzilla Threshold, donning Green Kryptonite armour, fully accepting that he may have to stop Regime!Superman permanently.
The Reverse Flash is trapped in the past due to a time paradox caused by the Regime killing one of his ancestors, meaning he can no longer go back to his own timeline. This implies that in Thawne's timeline, the Joker did not murder Lois, didn't cause the Regime to rise and the events of Injustice weren't supposed to happen. None of this was ever meant to be. Which means something must have altered the timeline somehow to make these things happen.
Perhaps a Time-Boom caused by Reverse Flash travelling back in time?
If so, this is the most tragic event to punish Reverse Flash, especially since he's notorious to "unborn" people via time travel.
Or we could be going by Doctor Who rules, where time travel means you're locked into events and just as affected by whatever happens like everyone else.
Lets hope that those Ace o'Club patrons aren't inhaling any of Scarecrow's fear gas.
But what if in every fight with Scarecrow, even the stage is part of the nightmare, considering he can tear a hole in reality in each and every one of them? Unless you have enough willpower, you can't beat him in his own turf. Your fear, his world.
Brainiac doesn't just exist in a humanoid body - he's an android who exists throughout his own machinery, including his ship - the ship Superman fused with in his ending. Brainiac has, in multiple different continuities, been shown to exert control and influence over anyone connected to his machinery. This means that Superman's Prophet Eyes may not be a sign of the fusion. Brainiac may very well still be alive have already or be in the process of taking over Superman. Superman's ending doesn't exert his will throughout the universe; it allows Brainiac to conquer all known life.
After Brainiac's defeat, Superman alerts people that some cities are still digitized on Brainiac's ship and some were deleted altogether. We only see Gotham returning in-game, with Metropolis and Coast City being referenced as being either trapped or destroyed (which isn't clarified). However, that still leaves questions as to what Earth cities might be missing or destroyed by this event. Black Adam specifically mentions Beijing and Moscow between Chapters 3 & 4, so what about their fate? What about Detroit ("the Motor City"), referenced in Cyborg's arcade ending? What about other major cities across the world that were picked up as well?
During the Flash's chapter, Deadshot informs him that Gorilla Grodd is forcing his service because Grodd controls the explosive in his head, stating "his paw's the detonator." Later on, Grodd states that the Society's members have disbanded. So... what happened to Deadshot? Did he somehow recover the detonator (assuming the "paw's the detonator" thing was metaphorical) and run? In the case of his minions quitting wholesale, it doesn't seem unlikely for Grodd to blow up Deadshot for good measure...
Possible Scenario: Deadshot challenged Grodd to do it, as he would rather die than continue to serve Grodd and help destroy the world. Grodd, thinking it wasn't worth the effort, let Deadshot go, assuming that he'll just die when the Earth is destroyed.
What Deadshot said was "His paw's ON the TRIGGER", not "his paw's the detonator". Presumably, he either recovered it himself, got blown up, or Grodd just never bothered. It's also possible that retrieving the detonator was what Batman tasked Firestorm with. He might've destroyed it just before Grodd or Brainiac found him.
Even if the Absolute Power ending (and by extension Superman's Arcade Ending) aren't confirmed to be canon, consider that due to the multiverse's nature, there is one reality where Superman bonded with Brainiac, turned Batman and all who resisted him into his slaves and now wants to expand his Regime across the universe... And the next universes, indicating that these events might have happened all along.
During one pre-battle intro between Brainiac and Darkseid, Brainiac asks Darkseid if he's a god and Darkseid basically says yes and adds that he's from Apokolips, to which Brainiac nonchalantly responds with "Noted for Classification". This suggests that after Brainiac's done with Earth, he may seek to invade Apokolips shortly afterwards, and New Genesis likely won't be far behind.
Superman enslaving Batman in the Absolute Power ending has some pretty horrific implications in itself. Consider: what would Superman do with a brainwashed Batman? Far as we know, Superman could force Batman into breaking his no-killing rule constantly, forcibly staining Batman's hands with the blood of countless people, possibly even making Batman kill his remaining allies (like Catwoman for example) and having them turned into brainwashed minions. This could be so horrifying to Bruce that even if he somehow got free of Superman's control, the immense psychological trauma he'd suffer could leave him barely able to function, and that's just assuming he doesn't become suicidal. Not to mention, Batman seeing himself forced to kill may likely cause him to lose any will to start another rebellion against Superman.
Also in the Absolute Power ending, when Superman orders Supergirl to become The Dragon to his restored Regime, she is faced with a Sadistic Choice: either she reluctantly rejoins his faction, or worse, Superman forcibly turns her into a brainwashed robotic monstrosity. Being that she's powerless, Superman knows she will be on his side one way or another. And in Superman's arcade ending, while Supergirl's fate is left vague, who's to say that Superman forcibly converted her into a machine even when she reluctantly joined the Regime as a way to prevent her from rebelling against him after she realized the ugly truth about him and his Regime teammates?
Dr Fate and Swamp Thing have returned to life after seemingly being erased from existence on Year 3 of the previous Injustice comic, and so does Trigon, who appeared in the previous game which takes place after the prequel comic. This means Mr Mxyzptlk is also somewhere and the last time he and Trigon fought, the reality was nearly unmade because of their conflict.
Dr Fate decides to defy the Lords of Order and tries to save Ollie and Dinah's lives by taking them to another Earth when he senses Brainiac's approaching. Now, consider Metropolis since that was a disaster leading to a chain of events that turned this alternate Earth into a horrible Crapsack World to live and Dr Fate did not intervene, nevermind that it was a catastrophe that he could have easily solve on his own since we are talking about a terrorist like the Joker using mundane means (in contrast to an alien conqueror like Brainiac). The disturbing implication is that he couldn't or wouldn't defy the Lords of Order, which means they allowed all these events to transpire for some unknown reason and it doesn't help Raiden's ending reveals that the they are outright malevolent.
Brainiac is confirmed to be a Multiversal Conqueror in this continuity rather than just a mere Galactic Conqueror, as Raiden finds out in his Arcade Ending that Brainiac would have likely collected Earthrealm if he hadn't killed him. And at least one Multiverse event features an alternate version of Brainiac that has conquered at least 17% of the Multiverse. It's even harder to imagine being safe from him where other versions exist that might be just as powerful.
The Flash can do his supermove many times in multiple fights. The ancient Egyptians must have had to rebuild the Sphinx's nose over and over again because the Flash kept warping in and smashing people into it. Meanwhile, that one T-Rex must have gotten pretty annoyed with the Flash smacking him in the face with various people all the time.
Maybe he keeps going earlier and earlier back in time every time that he activates his Supermove?
The weirdness is most apparent when the Flash manages to do two Supermoves in the same match, smashing the Sphinx's nose twice within a few short minutes.
Knowing the Flash's powerset, it can be assumed that instead of running through time, he's going to alternate dimensions. Therefore, he's destroying multiple Sphinxs and annoying multiple T-Rexes, which kinda makes it worse...
So if Scarecrow's demonic form is just a projection of Fear Gas, how does it affect Poison Ivy (whose powers include immunity) or Harley Quinn (who's been vaccinated by Ivy to the same effect)?
Superman has also spent a good amount of time in a red sun prison. He mentions needing to recharge at the Fortress of Solitude's solarium after the Regime and Batman's allies agree to a temporary truce to take down Brainiac, so he likely hasn't regained his old strength.
In the case of Harley, the story mode offers a simple Hand Wave: Scarecrow has a new, more powerful formula that she hasn't been immunized against, one that could possibly overcome even Ivy's immunity.
On most stages, Brainiac's supermove makes sense. However, what about when he uses it on his "home stage"? It's kinda weird to zap the opponent with your ship when you're inside that ship. Does he have a spare or something? (yeah yeah, Gameplay and Story Segregation, but it's still weird.)
In the case of Arcade Mode, there's a convenient out if it's your Brainiac, at least: It's a different Brainiac, presumably 5 brought his own ship back from the future and made it in the original Brainiac's ship's likeness.
