* There's something about the absurdity of an unconscious Scorpion sitting in the passenger seat of the Batmobile as Batman drives to Gotham.
* The Joker has a habit of stealing whatever scene he’s in in this game.
** When Scorpion, in search of Kitana, comes across The Joker, who immediately does his [[{{Troll}} usual schtick]], Scorpion silently regards the clown for half a second before [[ScrewThisImOuttaHere turning around and walking off.]] The best part is just how huffy Joker gets at this...before spring-loaded-boxing-gloving Scorpion in the back of the head.
** At the end of Captain Marvel's part of the DC story, he reveals the identity of the OriginalGeneration BigBad behind the merging of the two universes to the DC villains and Superman. The Joker's reaction?
-->'''Joker:''' '''''[[TheKhan KHAAAAAAAAAAAAAAANNNNNNNN!!!]]'''''
** Deathstroke telling him to shut it or he'll gut him.
** [[NightmareFetishist "Yay, we're allll going to hell!"]]
--> '''Catwoman:''' And if you're not a good boy, we'll leave you there.
* The incredibly underwhelming "GoombaStomp" Fatality from Kano, widely considered to be the worst fatality in the MK series. Even some of the [[ThouShallNotKill Heroic Brutalities]] look more deadly!
* Almost all of the non-Fatality victory animations have the fighters leave the opponent alone after they're defeated. The only exception is The Joker, who takes a page out of Johnny Cage and flat-out '''''[[GroinAttack STOMPS ON THEIR NUTS WHILE THEY'RE STILL DOWN]]'''''.
