** One of the dialogue interactions has Atrocitus tell Supergirl she "could wear a red ring" – [[Comicbook/RedDaughterOfKrypton which she did for several months]] in the ''ComicBook/New52''. Supergirl [[ItWillNeverCatchOn makes fun of the idea]].

* One of the character intros has Power Girl bring up a "Monitor named Bob" and Red Hood responds by asking how she knows Bob. This is referring to the Monitor of New Earth who saved Jason Todd from being murdered for his corruption by the Monitor Solomon in ''Comicbook/CountdownToFinalCrisis''.

* Starfire's Super Move references the animated ''WesternAnimation/TeenTitans'' opening, where she [[https://68.media.tumblr.com/b6bd6a7011f5e4631816f903bc1fc8ce/tumblr_otimgiD9f21veenguo3_r3_540.gif throws starbolts at the enemy]] just like she [[https://68.media.tumblr.com/3fd970786712307a17c540734c05a3df/tumblr_otimgiD9f21veenguo1_r1_540.gif does in the cartoon towards the camera]].

* Starfire's Victory thing has her do a mustard and pizza party, and the original Titans was her, Dick!Robin, Beast Boy, Cyborg and Raven. [[WesternAnimation/TeenTitans Wonder why]]? Her new Titans also including Blue Beetle is also a touch to [[WesternAnimation/DCUniverseAnimatedOriginalMovies the newer ones.]]

** Raven and Cyborg in this scene bear designs that strongly resemble their original appearances in the comics, albeit modernised. Whereas Dick Grayson's Robin costume makes him look much like he's wearing a more adult version of his ''WesternAnimation/YoungJustice'' Robin suit.

* Brainiac 5's Arcade ending features an {{Homage}} of the cover of ''Adventure Comics'' #247, with Cosmic Lad, Lightning Lad, and Saturn Girl putting Brainiac 5 (and not Superboy) on trial in (almost) the same arrangement.

* In one of his intros with Jay Garrick, ComicBook/{{Hellboy}} asks Jay if he's ever meet the Lobster, to which Jay replies that "someone knows his history", with Hellboy following up with "History? I've fought alongside the guys ghost". While Hellboy is referring to the Lobster from his own series, Jay is referring to a villain with the same name that ComicBook/PlasticMan fought in ''Plastic Man #4''.

* Aquaman's default armor design is based on Jason Momoa's costume in the [[Franchise/DCExtendedUniverse DCEU]], with most of the torso bare and tattoos on the shoulders and arms. Wonder Woman also resembles her DCEU design.

* One of Harley Quinn's Legendary tier Weapon unlocks is named Mad Love, the name of one of the most iconic Quinn stories in the comics, as well as the episode Batman The Animated Series that showed her origin story for the first time. The name is also used for one of her color shadings.

** With the right gear and shaders, Flash can look like Godspeed, the newest villainous speedster who was introduced in DC's Rebirth line.

* In Green Arrow's Arcade Ending, [[spoiler:he joins a reality-travelling Justice League composed of ComicBook/{{Flashpoint}} Wonder Woman, [[ComicBook/SupermanRedSon Soviet Batman]] and [[ComicBook/TheMultiversity Earth-23 Superman]] after they saved his home.]]

* One of Green Arrow's Epic items is "The Bow That Took Slade's Eye".

* Has quite a few for Poison Ivy and, surprisingly enough, Film/BatmanAndRobin, with numerous quotes taken directly from the film, and a limited-time in-game event that features Bane as a 'henchman' who can be called in for assist attacks, VideoGame/MarvelVsCapcom-style. Naturally, in order to obtain the special condition rewards, you must play as Poison Ivy.

* Enchantress' AsskickingPose [[https://i.redd.it/2d2z4nuraa801.jpg as she activates her super move]] appears to be a take on the one from [[https://www.bleedingcool.com/wp-content/uploads/2017/06/Image-20-1-600x896.jpg this page]] in ''Comic/SuicideSquad'' Vol. 5 #20 (2017).

* One of Flash's lines against Green Arrow is suggesting that he hit the salmon ladder, something his ''Arrow'' counterpart did frequently.
* When the [[Franchise/TeenageMutantNinjaTurtles Turtles]] jump into combat in the Fighter Pack 3 trailer, the poses and attacks they use are similar to ones they used in both the [[WesternAnimation/TeenageMutantNinjaTurtles1987 1987]] and [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003]] series' intros.
** In addition, their win animation has them eating a slice of pizza and tossing the rest of it at the screen, just like what Raphael does in the opening to ''WesternAnimation/TeenageMutantNinjaTurtles1987''.
** The Turtles' super move ends with them slamming the opponent between their shells while saying "Shell shock!", something they did in [[Film/TeenageMutantNinjaTurtles the original live-action movie]].
** Among the stickers on Michelangeo's skateboard include an apple with the word "Big" written on it and a sticker reading "3AM". Together, this serves as a nod to the first stage in ''VideoGame/TeenageMutantNinjaTurtlesTurtlesInTime''.
*** In modes where you don't have access to Gear, [[https://twitter.com/noobde/status/961313881145708545 a character select sub-menu]] directly inspired by ''Turtles in Time'' will let you choose between the Turtles.

** They are from the two different {{Alternate Timeline}}s[[note]]''VideoGame/MortalKombat9'' was a ContinuityReboot separating all the previous installments from the sequels to this game[[/note]] and must fight to prevent their [[MergedReality merging]]. [[HilariousInHindsight Funnily enough]], this would eventually be rather close to the plot of NRS's next game ''VideoGame/MortalKombat11''.

* Kano seemingly asked Bane to join the [[BanditClan Black Dragon]] according to Raiden before a match against him.

* When Superman and Swamp Thing fight, Superman mentions that he's had some bad experiences with plants, which Swamp Thing recognizes stems from [[ComicBook/ForTheManWhoHasEverything an encounter with the Black Mercy]].

* Starfire's Victory thing has her do a mustard and pizza party, and the original Titans was her, Dick!Robin, Beast Boy, Cyborg and Raven. [[WesternAnimation/TeenTitans I wonder why]]?

* Both Sub-Zero and Raiden reference the events of ''VideoGame/MortalKombatVsDCUniverse'' and its final boss Dark Kahn when meeting with other character featured in this game (Flash, Joker, Batman, Darkseid, and each other).

** When claiming that the Elder Gods would stand aginst him, Darkseid replies that his "toothless serpents" will not stop him.[[note]]In ''[=MK9=]'' the Elder Gods and Raiden destroyed Shaoh Khan with the help of several small etheral dragons.[[/note]]
* When meeting with [[ThePollyanna Starfire]] Raiden will declare that her heart is as pure as the Jin Sei from ''VideoGame/MortalKombatX''.

* In their win animation, the Ninja Turtles procure a box of pizza. Printed on the side of the box is "Caution: Toasty!" [[note]]A famous easter egg in the ''Mortal Kombat'' games is developer Dan Fordan appearing in the corner of the screeny proclaiming "TOASTY!" when one kombatant is struck with an uppercut, as well as in one of Scorpion's Fatalities.[[/note]] Goes even farther with Michaelangelo lovingly telling the pizza slice "Get over here."

* Sub-Zero's victory animation is his infamous "spine rip" Fatality from ''VideoGame/MortalKombat1''...except this time, shown from the perspective of [[TheFourthWallWillNotProtectYou his victim]].

* In Sub-Zero's ending, he says he got transported to the Injustice Universe while he was [[VideoGame/MortalKombatX forcing Kotal Kahn to retreat back to Outrealm.]]

** As the Batplane flies in, removing the Fulton system, it silhouettes the moon in the same way that it did in ''Film/{{Batman}}''.
** Not to mention the way it catches the Fulton (between the "ears" of the silhouette) is similar to how it caught Joker's parade balloons in the same movie.

She especially likes [[BreadEggsBreadedEggs putting tutus on toy cars]]."[[/note]].
