-->--'''MKII's AttractMode''' summarizes the events thus far

The original ''[[VideoGame/MortalKombat1 Mortal Kombat]]'' was a huge hit, making a sequel inevitable. In 1993, the sequel -- '''''Mortal Kombat II''''' -- was unleashed in arcades before being ported to the SuperNintendo, GameBoy, SegaSaturn, Sega 32X, SegaGenesis, Sega Game Gear, PlayStation, PC and Amiga.

[[EvenBetterSequel And it was awesome.]]

Shang Tsung's plan to [[TakeOverTheWorld conquer Earthrealm]] through the titular tournament was foiled. The Emperor of Outworld, Shao Kahn, is furious with Shang Tsung's failure to achieve victory in Mortal Kombat. As Kahn [[YouHaveFailedMe prepares to end]] the sorcerer's life, Tsung comes up with an idea to save his skin: since the invitation to Mortal Kombat cannot be refused, if the Earthrealm warriors were challenged to a tournament in Outworld, [[ButThouMust they would have to accept]] -- and, once there, Kahn's Outworld warriors (led by Shokan warrior Kintaro, who seeks revenge for the death of Prince Goro) could kill them and conquer Earthrealm itself. Kahn approves of Tsung's idea and restores his youth as a gift. Earthrealm's warriors accept Kahn's challenge, and once in Outworld, they come face-to-face with numerous new foes, all of whom are ready to crush a few skulls.

''Mortal Kombat II'' took its predecessor's gore level and ramped it up by giving each character an extra Fatality to their characters and creating more stage-specific Fatalities. It also added two new {{Finishing Move}}s -- the Babality (which [[ExactlyWhatItSaysOnTheTin turns the opponent into a baby]]) and the Friendship (a NonLethalKO which had the characters doing friendly things) -- as potshots at the MoralGuardians who were incensed with the first game's violent content.

This game brought back the entire playable cast of the first game (sans ''[[ActionGirl Sonya]]'' and ''[[SmugSnake Kano]]'', who were trapped by ''Shao Kahn'' in his stage), made ''[[EvilSorcerer Shang Tsung]]'' and ''Reptile'' playable characters, and introduced ten new characters: playable characters ''[[RebelliousPrincess Kitana]], [[ColonelBadass Jax]], [[BladeBelowTheShoulder Baraka]], [[EvilCounterpart Mileena]],'' and ''[[NiceHat Kung Lao]]''; non-playable secret characters ''Smoke, [[FemmeFatale Jade]]'', and ''[[SdrawkcabName Noob Saibot]]''; sub-boss ''[[TheDragon Kintaro]]''; and final boss ''[[BigBad Shao Kahn]]''.

Followed by '''VideoGame/MortalKombat3'''.
!This series provides examples of:
* AIBreaker: Kintaro and Shao Kahn are easily beaten by jump kicks and Mileena's teleport move, respectively.
* BackupTwin / LegacyCharacter: After the original Sub-Zero was killed off following the events of the previous game, his younger brother assumes his former identity. [[note]]Later it is revealed that Noob Saibot is actually Sub-Zero's spectre, but this wasn't established yet in this game.[[/note]]
* BigNo: Should you best him, Shao Kahn will say [[RuleofThree "No! NO! NOOOOOOOOOOO!"]]
* BlatantLies: When you gain access to Jade or Smoke, the game says, "Now you must battle with an undiscovered warrior from Mortal Kombat One." Needless to say, neither character was ever in the first game.
* BloodierAndGorier: [[VideoGame/MortalKombat The original]] was already rather bloody, but this one managed to surpass it.
* BonusBoss: Jade, Smoke and Noob Saibot, who can only be fought via certain conditions being met. [[note]]Using only low kicks before the ? in the tournament ladder, pushing Down and Start when Dan Forden says "Toasty!" in the Portal stage, and winning 50 matches in a row, respectively.[[/note]]
* DarkerAndEdgier: Even in comparison to the original, ''[=MK2=]'' was arguably even darker. The developers realized this, and decided to lighten things up a little by introducing...
* {{Defeat Means|Friendship}}... [[DefeatMeansFriendship FRIENDSHIP?!]]
* DemotedToExtra: Sonya and Kano went from being playable characters, to chained up in the background of Shao Kahn's stage. They were excluded for the new characters due to being the least popular characters from the first game.
* FateWorseThanDeath: Babalities.
* TheForeignSubtitle: The Japanese version featured the subtitle ''Kyukyoku Shinken'' (The Ultimate Divine Fist).
* ImpaledWithExtremePrejudice: This game didn't introduce the concept of Stage Fatalities (the first one was), but it was featured in two stages; the Wastelands where one can see a few corpses impaled in the background and the Kombat Tomb, where you can pull this on your victim by punching him up onto a ceiling of spikes.
* KidAppealCharacter: So far, the only one in the [=MK=] series to date is Kidd Thunder, a [=NPC=] who appears in Raiden's Friendship.
* KissOfDeath: Kitana gives one to her opponent as a [[FinishingMove Fatality.]]
* LighterAndSofter: Friendships and Babalities.
* TheManBehindTheMan: Shao Kahn was this to Shang Tsung.
* NotJustATournament: The Outworld Mortal Kombat is a trap laid by Shao Kahn, to not just kill the Earthrealm warriors but also conquer Earth.
* NowBuyTheMerchandise: Scorpion, Sub-Zero and Reptile had this as their Friendship, in which they would advertise their own dolls. Considering how hard it was around that time to come to know about the actual codes to perform them, however, you could think those finishing moves can be seen as more of a parody of the trope than anything else. But in all reality, that wasn't entirely PlayedForLaughs; there ''was'' an actual line of action figures by Hasbro being sold around that time after all.
* PaletteSwap: Added two new male ninja (Noob Saibot[[note]][[spoiler:later retconned into the original Sub-Zero BackFromTheDead]][[/note]] and Smoke) and three female ninja (Kitana, Mileena, Jade) to the existing group of Sub-Zero, Scorpion, and Reptile.
* PerfectPlayAI: First appearance of the trope formerly known as MK Walker.
* TheComputerIsACheatingBastard: The AI in this game is absolutely ridiculous. After the second round, the CPU does A LOT of things are IMPOSSIBLE for human players to do. Like dodging an uppercut or blocking throws and counterattacking with their own. The computer is sure to make anyone rage.
* ThePowerOfFriendship: Lampshaded. In response to parents complaining about the grotesque violence of the Fatality finishing moves, the second and third installments added a finishing move called [[DefeatMeansFriendship Friendship]], which would allow you to win the match without killing the opponent, along with showing an animation of your character doing something sickeningly friendly.
--> "Liu Kang wins! Friendship! ...Friendship?"
* RunningGag: Dan "Toasty" Forden's appearances. Also the appearances (specifically in the Genesis ports of the series) of Probe president Fergus [=McGovern=]; he even got his own "Fergality" in this game's Genesis port (it could only be done by Raiden, though).
* SdrawkcabName: Noob Saibot has nothing to do with {{Noob}}s.
