Tons of past events become funnier in this franchise.
Characters and elements introduced in Mortal Kombat
- Liu Kang's Fatality was considered the lamest in the game because of its complete lack of gore. It made a comeback as his X-Ray move in 9, and it was far more destructive as a "non-lethal" super move.
- Jean-Claude Van Damme was the original choice to play the titular alien in Predator. Cue the original Predator coming as a DLC character for X and facing Johnny Cage, who was inspired by JCVD's character in Blood Sport.
Characters and elements introduced in Mortal Kombat II
Characters and elements introduced in Mortal Kombat 3
- A commercial shows something trying burst out of a teenager's chest. Now with Alien in X, MK has actual Chest Burster finishers.
- Cyrax, Sektor and Smoke plus Cyber Sub-Zero in 9 were more than a little visually inspired by the Predator, and other elements of the hunter found their way in their later appearances. As of X, the original Predator becomes playable via DLC with the three cyborgs following suit as Triborg.
Characters and elements introduced in Mortal Kombat 4
- In his arcade ending, Raiden flies into the sky in the classic Superman pose. Eleven years later, Raiden not only gets to fight Superman himself, but the two are rivals. Twice.
- In Spy Hard, the antagonist General Rancor said to Dick Steele, while proclaiming what he believed to be the future of the Internet: "What's left of you will have to watch helplessly while I play Mortal Kombat with the entire world!" Eight years later Deception, the first Mortal Kombat game to feature online gameplay, was released.
- Though this can also be "Funny Aneurysm" Moment for some as well, Johnny Cage bumping Sonya Blade out of the way to rush to the top of the pyramid is funny based on the fact that in the new timeline they got married, had a child, and got divorced some time after Cassie's birth.
- Then there's Kurtis Stryker's ending from this game. While they refrain from calling him a superhero, that more or less sums up what he becomes as a super powered vigilante upon absorbing Blaze's power. Not just only would the next game be a crossover with the DC universe, but Netherrealm Studios would also make Injustice: Gods Among Us.
- Sektor's ending talks about how he, Cyrax and Smoke, fused into a new cybernetic being. Fast forward to the rebooted timeline and the Kombat Pack 2 for X introduces Triborg.
- The sole presence of Kreate-A-Fighter is this: so far, before 9 was announced, there were Freddy Krueger and Skarlet videos, and before X there were Alien, Predator, Tremor and Jason videos. Oh, and if that wasn't enough, Midway/Netherrealm also got to work on three different games featuring DC characters, the three of which have MK characters either in crossover form or as Downloadable Content.
- Freddy Krueger wouldn't be the last horror movie villain to show up in the series, as his rival Jason and fellow icon Leatherface showed up in Mortal Kombat X as playable kharacters.
- Freddy Krueger is notably voiceless and not based on Robert Englund in his appearance. Fast-forward to Injustice 2 and Batman villain Scarecrow is reimagined as a Krueger-like being with Englund as his voice actor.
- One Konquest mode exclusive enemy has the name "Wu Lae." Saying that name aloud nowadays will definitely get a laugh or two from Quan Chi's fanbase. explanation
- "Kreate A Fighter" mode is this, especially with Mortal Kombat 11 displaying what happens when both the original and new timelines divert... and merge. So we have OT!Scorpion fighting against either his new timeline self, or any of the characters who only appeared in the new timeline.
- After returning from their assigned missions, Shang Tsung mocks Kano for his defeat saying "A clown? You were defeated by a clown?". In the next game, Shang Tsung would turn into a clown while recreating the Joker's Fatality from this game.
- It's also quite ironic that Warner Bros., the owners of DC comics, the same company that collaborated with the then-Mortal Kombat Franchise owner Midway Games to create this controversial game, would later successfully resurrect the franchise.
Characters and elements introduced in Mortal Kombat 9
- With Karen Strassman voicing Kitana and Lani Minella voicing Sindel, we essentially have Rouge the Bat playing both mother and daughter. Minella voiced Rouge in Sonic Adventure 2, Sonic Heroes, and Sonic Battle, while Strassman assumed the role starting in Colors and Free Riders.
- One of the achievements of Mortal Kombat 9 is "There Can Be Only One." Christopher Lambert, who played Raiden in the first movie, also played Connor MacLeod in the Highlander movie.
- The Robot Chicken Season 1 sketch "Enter the Fat One" features Joey Fatone entering a martial arts tournament to avenge the deaths of his *NSYNC bandmates at the hands of the Yakuza. His battle with Storm Shadow has Fatone punch the Cobra ninja so hard in the face, the viewer sees Storm Shadow's skull fracture, his blood vessels burst, and his heart and intestines rupture before he completely falls apart. This was back in 2005, long before the 2011 reboot introduced X-Rays, attacks that show damage to the victim's bones and internal organs in a similar manner. It should also be noted that, during his (incredibly brutal) Training Montage, Fatone is mercilessly mowed down by the likes of Scorpion, Sub-Zero, and Smoke.
- Challenge Tower #115 has players using Stryker, voiced by Matthew Mercer. Said challenge is called High Noon.
- Stryker's ending: he rejects a movie based on his exploits because "never would he allow himself to be portrayed by Johnny Cage." Johnny's daughter, Cassie Cage, in X, has numerous similarities to Stryker in both attire and moveset.
- Also related to that ending, one magazine cover that's shown at the end of his ending mentions "Ancient Mayans Warned of Outworld Invasion" which poked fun at the 2012 Mayan Doomsday predictions. Now in 2015's Mortal Kombat X, we have the debut of Kotal Kahn... who invades Earthrealm near the end of Story Mode.
- Scorpion's ending with the spirits of the Shirai Ryu helping him destroy Quan Chi foreshadows both his Inferno variation in X and him canonically killing Quan Chi after discovering the truth of his family's murder.
- Baraka's ending had the Tarkatans becoming Shao Kahn's favored race after discovering a betrayal from Shang Tsung. In X, the Tarkatan's became Mileena's (Shao Kahn's heir) bodyguard race.
- Liu Kang's ending had him asking the Elder Gods to grant him Thunder God status at Raiden's expense, with Shang Tsung's ending revealing that he went mad after being granted such powers. At the end of this game's Story Mode he becomes King of the Netherrealm.
- In 9, Freddy Krueger was revealed as the final DLC character for the title. Cue X, where fellow slasher movie icon and old enemy Jason Voorhees is announced as a member of the Kombat Pack DLC... on Friday the 13th, no less.
- The Portal Kombat joke around the release of this installment. "Portal Kombat" became one of the modifiers for the Test Your Luck mode in X.
- Jax's story chapter has him discussing with Raiden about how anybody could have won the tournament, even joking about him beating Shang Tsung. In X, his opponents in his chapter are people who defeated him or were empowered by Shang Tsung and he beat all of them in a single day.
Characters and elements introduced in Mortal Kombat X
- Kelly Hu, who voices D'Vorah, has met Jason before.
- If you pit Scorpion against the Predator, it wouldn't be the first time a man named Hanzo had to face them.
- Since both the Predator and the Xenomorph are both guest fighters, it means that we can have Alien vs. Predator again. The same thing applies to both Jason Voorhees and Leatherface, as this isn't the first time the two have met and fought.
- Fan-made game Terrordrome the Game: Rise of the Boogeymen had Freddy, Jason, Leatherface, and the Xenomorph-expy Pumpkinhead playable in a fighting game even before Freddy appeared in MK9.
- With the addition of Freddy Krueger to the Mobile version, we can now have Freddy vs. Jason.
- There's also the fact that, in this game, Johnny is voiced by Andrew Bowen, who previously impersonated JCVD on MADtv.
- This is the second game in the last two years where Patrick Seitz has made an emotional speech while laying the beatdown on someone.
- Kung Jin getting a Green Arrow costume (in the Medieval pack, called "Marksman") right after Netherrealm just finished the work on a DC fighting game featuring Oliver Queen himself.
- Cassie Cage's fatality involves taking a selfie with her dead opponent and uploading the pic on social media, which was something that "Weird Al" Yankovic sang in "Tacky" (about taking selfies with the deceased). Months after this game was released, Sideshow Bob would do the same thing with Bart's corpse in the Treehouse of Horror XXVI segment "Wanted: Dead, then Alive".
Characters and elements introduced in Mortal Kombat 11
- This game involving having use of travel traveling elements which ultimately in the end is set to be used to rebuild the universe once Liu Kang becomes a god thanks to Raiden and takes control of the hourglass after Kronika is defeated. Ironically enough, this game came out right on the week of Avengers: Endgame which likewise ended with time travel being used to fix the problem caused in Avengers: Infinity War. Heck the heroes even have to fight the past versions of Thanos and his Black Order in the climax of the film. Talk about strange minds thinking alike. It was also likewise the End of an Era for both franchise. MK finishing its new universe trilogy and Endgame capping off it's Myth Arc started in Iron Man, with both franchises leaving on the door opening of new adventures to follow from the previous continuity.
- Zasalamel from Soulcalibur VI was compared to Raiden due to having a similar role to what Raiden did in Mortal Kombat 9, having a vision from his future self and attempting to change it from there. Then we got Geras, who, like Zasalamel, is a Scary Black Man with a time motif and Resurrective Immortality.
- In Injustice 2, The Atom (voiced by Matthew Yang King) compares himself and Vixen (voiced by Megalyn Echikunwoke) to Jacqui and Takeda during one of their pre-battle intros, only for the reference to go right over Vixen's head. Come 11, and not only does Echikunwoke voice Jacqui herself, but King lends his voice to Liu Kang.
- Cetrion's reveal trailer prompted comparisons between her and Aang from Avatar: The Last Airbender. It is therefore fitting that her final fight in the game is against a man with power over fire and lightning.
- In this game, Shinnok could go One-Winged Angel in his boss battle. In X, he can do it again via poisoning and absorbing the Jinsei's power.
- The "Real ninjas wear Nikes" meme takes on a whole new meaning, considering Special Effects Failure where freeze frame bonuses allows us to see Nike's swoosh on Scorpion and Sub-Zero's shoes.
- The Belligerent Sexual Tension between Johnny and Sonya rides the line between this and Harsher in Hindsight come Mortal Kombat X - they're just as belligerent as ex-spouses.
- In Evil Con Carne, Hector let Boskov get Cod Commando. Hector tells Boskov to finish him. Goro and Boskov's vocal effects were both done by Frank Welker.
- In WMAC Masters, Chris Casamassa (Scorpion's actor) had the Red Baron of "Red Dragon", years before Mortal Kombat: Deadly Alliance introduced a clan called Red Dragon.
- One of the more noticeable differences fans noticed was that Shang Tsung, portrayed by Cary-Hiroyuki Tagawa, was depicted much younger than his original elderly appearance, drawing comparisons to his younger appearance seen in MKII. Twenty years later, Tagawa would reprise the role in the second season of Mortal Kombat: Legacy, now as an older Shang Tsung. It finally comes full circle with Mortal Kombat 11, where Tagawa finally appears in a proper game itself reprising his most famous role, now sharing the soul stealing sorcerer's original elderly appearance.
- As noted above, Jean Claude Van Damme was offered the role of Johnny Cage but turned it down to play Guile in the Street Fighter movie. Robin Shou, who played Liu Kang in the MK movies, would later go on to play Gen in the second live action Street Fighter movie. This is especially funny when taking into account that Van Damme actually was offered a chance to reprise the role of Guile in Legend of Chun Lie but turned it down. Meaning we almost had the actor who inspired Johnny Cage (and is the reason for the existence of the Mortal Kombat franchise in the first place) on screen with the guy most known for playing Liu Kang. Also, Shou's character in Legend of Chun Li serves as a mentor figure to a character who, like Liu Kang in the movies, was on a quest for vengeance for the death of a family member.
- The film features a scene where Rain announces to Shao Kahn that he's captured Kabal and Stryker, and later both of them would be killed. In 9, they are partners in the NYPD. It could also double as Harsher in Hindsight given MK9 also had them die together just like this film.
- The show being done in Timm Style long before events such as Mortal Kombat vs. DC Universe, Warner Bros. going on to officially own the franchise, and DC's tie-in comic to Mortal Kombat X.
- Related to the above, Raiden and Stryker are voiced by Clancy Brown and Ron Perlman respectively who have served as the voices of Lex Luthor in the DCAU and Slade Wilson in Teen Titans. In fact, Raiden being voiced by Superman's arch nemesis makes Raiden and Superman being rivals in MK vs DCU inevitable.
- The Sub-Zero/Smoke episode, two-fold:
- One flashback gave us a non-canon glimpse of Cyrax and Sektor before they underwent automation; they were respectively shown to be Asian and Black. While we've known that (in canon) Cyrax has been shown to be dark-skinned at the least since his ending in Gold (additionally, his bio for this game confirms that he's Motswana), this game's story shows us all of the major Lin Kuei warriors before they were converted into cyborgs. Sektor is shown to be Asian, thus meaning that he and Cyrax swapped races between the games and the cartoon.
- Furthermore, Sub-Zero's Mortal Kombat 3 costume in Mortal Kombat 9 actually looks more like the Lin Kuei uniform he wears in one flashback of the very same episode as well.
- One of the missions in 9's Challenge Tower is named "It's Kombat Time!" and you play it as Sonya.
- An episode has Shang Tsung using an orb that grants the user control over earth, wind, water and fire. MK 11 features a villain with control over those very elements.
- Hydro tends to be a cyber-ninja version of Sub-Zero in the aforementioned MUGEN full games. Then it happened for real. On a lesser scale, Hydro also used water-based powers. Then came Rain.
- There's a Mortal Kombat fangame made using M.U.G.E.N known simply as Mortal Kombat Project. The default roster includes all the characters from the 2D games, plus one original character, Hydro, who originated in the comics. While he was a human Lin Kuei who could control water in the comic, in the game he's a cyborg who can control ice, essentially making him a cyborg version of Sub-Zero. Then the game came with Cyber Sub-Zero having a very similar movelist.
- This gets even better with the release of his Klassic Costume DLC, a blue version of Cyrax and Sektor's appearance from 3. It looks exactly like the MUGEN Hydro.
- And if that isn't enough, some of those MUGEN games also feature a female cyber Lin Kuei. Say hello to the rebooted timeline version of Frost.
- The Sub-Zero seen for most of the comic series is Bi-Han, the Elder Sub-Zero brother. Considering that almost every other media based off of Mortal Kombat has Bi-Han dying during the first tournament and his younger brother Kuai Liang taking up the mantle, it becomes quite funny that this media saw fit to keep Bi-Han alive for far longer. Add to the fact that Noob Saibot appears in this as a wholly separate character from Bi-Han and...
- In season 1, Johnny Cage is stated to have started out his acting career on Power Rangers. Season 2 has Kenshi played by Dan Southworth who portrayed the sixth ranger on Power Rangers Time Force.
- Related to the above. Mortal Kombat X has Johnny Yong Bosch, another Power Rangers alumnus (one who got the role Southworth once auditioned for no less), serving as the voice actor for new character Kung Jin.
