* Sindel is referenced by both Raiden and Sub-Zero when fighting against [[MakeMeWannaShout Black Canary]]. Raiden also finds Starfire reminiscent of the Edenian Queen due to her long floaty hair looking like Sindel's PrehensileHair and her ability to fly.

* 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]]. Darkseid even threatened Sub-Zero to do the same in this clash dialogue:

* 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. Braniac also closes the ending with the familiar Legion BattleCry "Long live the Legion!"

'''Darksied 1''': Wish to wager on this battle?

** 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 Shao Khan with the help of several small etheral dragons.[[/note]]

* 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."
* Sindel is referenced by both Raiden and Sub-Zero when fighting against [[MakeMeWannaShout Black Canary]]. Raiden also finds Starfire reminescent of the Edenian Queen due to her long floaty hair looking like Sindel's PrehensileHair and her ability to fly.

** 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''.

** One of the turtles' Legendary Gear sets is called "[[Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze Secret of the Ooze]]."

* One of Superman's MirrorMatch dialogs has one Superman stun the other by saying "Two words: beef bourguignon". This is a nod to the story ''Who Took the Super out of Superman'', where Lois prepared that dish for Clark before a romantic evening; it's since become an in-joke among the Superman fandom.

** Ditto with Bizarro, who states "This/That am job for ''Bizarro''!" in some of his pre-fight banter.

** It is also referenced in Joker's supermove, along with ''WesternAnimation/BatmanBeyondReturnOfTheJoker'': Joker beats his victim with a crowbar, electrocutes them, and finishes them off with explosives.
** One of Red Hood's mid-battle taunt also refferences it. "Should I kill you? Let's have a vote!"

* ''Very'' rarely, Raiden will have a secret third taunt animation, where he summons none other than "KIDD THUNDER!", in reference to his Friendship in ''VideoGame/MortalKombat2''.
