Cyber Sub-Zero (LK-52O)
- Voiced by: Jim MillerIn the original canon, Sub-Zero and Smoke attempted to escape from the Lin Kuei's automation program but Smoke was still captured and forcibly turned into an cybernetic assassin.During Mortal Kombat 9's story, Smoke is about to be captured by a team of robotic Lin Kuei until Raiden, who has been receiving premonitions of the future, intervenes and destroys the assault team. This, in turn, leads to Sub-Zero being captured instead of Smoke. Cyber Sub-Zero is the end result of that and also receives a story chapter in Story Mode.
For other tropes which apply to him, check the second game's character sheet. This is only for additional tropes which appear in this game.
- Alien Blood: He bleeds bright blue anti-freeze.
- An Ice Person: He is Sub-Zero, after all. He shares many of his moves with his human self.
- And I Must Scream: He remembers every horrific deed he committed under Shao Kahn while a cyborg, but was unable to go against his programming. And then it happens again after Quan Chi binds his soul to him. He just can't catch a break.
- Battle Aura: His body even emanates an icy mist.
- BFS: Made of ice, naturally.
- Body Snatcher: Shao Kahn's soul takes over his body in his arcade ending.
- Cybernetics Eat Your Soul: Ultimately subverted when Kabal knocks him out, allowing Jax to reformat him and restore his conscience. Also subverted in that the cybernetics prevented Quan Chi from being able to put Kuai Liang under his control as one of his revenants initially. While the necromancer's spells worked on Kuai's organic brain, his neuro-cybernetics could not be effected by magic and thus had to remove his technological enhancements to get rid of this impediment.
- A Day in the Limelight: He's the focus of Chapter 14.
- For Want of a Nail: Thanks to Raiden's knowledge of the future and the time changes resulted, Sub-Zero has been automated in place of Smoke.
- Ninja Pirate Zombie Robot: A Cyborg Lin Kuei, just like his fellow cyborgs... with a little Cyromancer thrown in for good measure. Add in "Outworld Emperor" for his Arcade Mode Ending and actually becomes 3 our of the 4 when his undead soul is taken by Quan Chi (making him a Ninja Robot Zombie, but no hints of piracy yet) in Story Mode.
- Retraux: Cyber Sub-Zero has a Klassic Costume, a blue palette swap of Cyrax and Sektor's klassic costumes.
- Status Quo Is God: Quan Chi restores his human body when he raises him as a revenant in the MKX prequel comics, which he retains when he is freed from Quan Chi's control and returned to life in MKX. In one of his intros with Jax, he appreciates the restoration as the only good thing to come out of being a revenant.
- Taking You with Me: His first Fatality. Cyber Sub-Zero latches onto his opponent Saibaman-style and self-destructs, leaving nothing behind except for his opponent's partially frozen lower body.
- Teleport Spam: In a fashion similar to Cyrax.
- Took a Level in Badass: As if Sub-Zero needed it or anything, but still.
- After his soul and free will are returned, he goes on to defeat Sektor, utterly wrecks Goro and Kintaro in a one-on-two fight, knocks Ermac's block off, and then gets to beat some sense into his big brother Noob Saibot.
- Subverted in the end, as Sindel slaughters him to the ground.
- Gameplay-wise, he has twice as many special moves as regular Sub-Zero, and he hits faster.
- Unwilling Roboticisation: Kuai Liang is captured and turned into a cyborg against his will with his mind controlled initially, thanks to Raiden's meddling with the timeline sparing Smoke from this fate.
- Abhorrent Admirer: Skarlet frequently humors most of the male fighters with varying degrees of flirtatious comments about stealing some of their blood. They don't find her unattractive, they just find her creepy.
- Absolute Cleavage: More prominent with her alternate skin and her UMK3 outfit for the Vita version. Several of her outfits in 11 show off some cleavage.
- Affably Evil: In the majority of her intros in 11, Skarlet is civil and calm when addressing the other fighters. Granted, in most of them she makes a claim for their blood, but at least she asks nicely.
- Ascended Glitch: Like Ermac and Blaze, she was born from an initial rumor. In the older arcade games, Kitana, Mileena, and Jade sometimes appeared in red outfits due to a programming glitch; fans named the glitch-character Scarlet (or Skarlet, if you prefer). Fans found her Dummied Out, and the first batch of DLC has revealed her.
- Ax-Crazy: So much that Shao Kahn keeps her chained up when he doesn't need her in order to prevent her from killing people he doesn't want dead. She's that unstable. Although she shows more self-control in 11, she is still very much intrigued at the prospect of taking her opponents' blood.
- Bad Powers, Bad People: Played With. Most characters consider Blood Magic to be especially creepy — especially when Good-aligned. Further, Blood Magic is extremely addictive, and Kotal Kahn makes it clear that Osh-Tekk avoid using to that degree. And, while Skarlet's addiction was created outside of her control by Shao Khan, Liu Kang says that it's not that which makes her evil — it's her willing devotion to Shao Khan that does.
- Bare Your Midriff: Her default outfit in 9 is essentially a really skimpy bikini.
- Blood Lust: Just look at her Fatalities... Skarlet might very well be Interplay of Sex and Violence personified.
- Blood Magic: Was taught this by Shao Khan. She enters fights via a pool of blood, and she also uses a projectile attack that's like a blood version of Johnny Cage's. According to her ending, she also grows stronger when the blood of others splashes upon her skin.
- Becomes a plot point in Chapter 18 of the X comics, as she wants to learn blood magik itself.
- Bloody Murder: Her modus operandi. Skarlet makes a habit out of shaping weapons from her element, not unlike Sub-Zero, and she won't hesitate to use your own blood against you.
- The Bus Came Back: After being absent for X, she returns as playable in 11.
- Cast from Hit Points: Her Blood Ball in Mortal Kombat 9. Jade also notes to Skarlet that her use of blood magic has a consequence of decaying her soul.
- Cat Fight: Downplayed (in that it not strictly for fanservice only) and mildly invoked in the Mortal Kombat X comics. During her fight with Mileena, the latter berates her for choosing to work with Reiko. Considering that Mileena had previously had an intimate relationship with the spoiler protected individual and Skarlet was involved with one with him at that time combined with Kotal Kahn quipping that "Earthrealmers say 'Hell hath no fury like a woman scorned.'", the implications are rather strong.
- Combat Stilettos: Used in her Eye Scream-worthy X-Ray Attack.
- Combat Tentacles: They whip and restrain poor folk, just like any tentacle should. Except Skarlet's tentacles emerge and are made from blood. It's her thing.
- Contract on the Hitman: Her siding with Reiko ultimately leads Shao Kahn's other assassin, Mileena, to turn on her.
- Crippling Overspecialization: While Baraka generously compliments her natural fighting skill, he claims Skarlet has forsaken it in favor of blood magic.
- Did They or Didn't They?: It's implied that she has some kind of history with Erron Black, as the of them share by far the most flirtatious dialogue. They reminisce on his history with her and Nitara, and Skarlet bitterly chides him about leaving, further stating that she still greatly desires his blood. This is still not much to go on.
- Distaff Counterpart: Basically a female Ermac with blood replacing souls. Skarlet is a being composed of countless warriors defeated by Shao Khan and was conceived as a rumor in the earlier games and eventually became an Ascended Glitch and is a red Palette Swap, pretty much mirroring Ermac's conception and design
- Downloadable Content: In her introduction in Mortal Kombat 9, the only newcomer among the DLC characters. She's on the starting roster in 11.
- The Dragon: An intro dialogue with Baraka has her state with him defecting from Shao Khan, she has been appointed as his right hand.
- Early-Bird Cameo: Before being introduced as DLC, in Story Mode, she appears among the entrants in the background during both Shang Tsung's Mortal Kombat tournament and Shao Kahn's Outworld tournament. Additionally, she appears tied up in Shao Khan's colosseum.
- Evil Redhead: Befitting her Color Motif, she has dark red hair.
- Evil Is Sexy: An in-universe example. Skarlet is very attractive despite her creepy demeanor, and she's aware of it enough to flirt and flaunt with other male kombatants.
- From Nobody to Nightmare: She went from street urchin orphan to one of the most revered Outworld assassins.
- Gone Horribly Right: Shao Kahn raised her to be a great enforcer, and she proved to be far more powerful and successful than he expected. So successful and ambitious, in fact, Shao Kahn warns her to not overly overstep her station. Noob Saibot also suspects Shao Kahn hides his best techniques from her out of fear she may overthrow him.
- Humanoid Abomination: According to her first biography. She's nothing more than a construct of the blood of fallen warriors mixed with sorcery and made to be entirely loyal to Shao Kahn; additionally, her strength increases when the blood of other fighters comes in contact with her skin. Essentially, Skarlet is to blood as Ermac is to souls. However, see Retcon below.
- Impaled with Extreme Prejudice: One of her fatalities in 11 involves using her Blood Magic to rip the blood out of her opponent, turn then blood into solid spears, and then shoves them back in.
- Knife Nut: Her weapons of choice appear to be throwing knives. In 9, Skarlet wielded a pair of wakizashi, the shortened Japanese blade that is often paired with a katana. Come 11, most of her weapon options are ceremonial daggers, with the odd wakizashi thrown into the mix.
- Leaning on the Fourth Wall: When Mileena does a roll that obliterates her legs, Skarlet proclaims that "Brutality... won't kill me...". Considering that Mileena does indeed have a Brutality in Mortal Kombat X that does just that, Skarlet's statement is rather metaphysical in that way.
- Leave No Survivors: Anybody opposing Shao Kahn's empire is fair game for her to go after, although Quan Chi takes priority and by said control she unwillingly kills her own master Shao Kahn.
- Mistaken Identity: A meta example. Many mistook her for Kira at first. When Ed Boon leaked her leg in a Twitter pic, she was originally believed to be a redesign for Sareena or Sindel.
- Not So Different: From Mileena. Both are particularly bloodthirsty (literally in Skarlet's case) female warriors who are loyal to Shao Kahn, as well as artificially created beings (prior to the below mentioned Retcon, at least) who wield small stabbing weapons in combat (sai and knives, respectively).
- Old Flame: Pre-battle banter indicates that Skarlet was once in a relationship with Erron Black.
- Pop-Cultural Osmosis Failure: Given she is from Outworld, she fails to understand Cassie Cage's Dracula reference in one of her intros in 11.Cassie: Bride of Dracula!Skarlet: Who is this "Dracula"?Cassie: Lemme tell ya, he's a catch!
- Power Echoes: Her mask in 11 gives her voice a metallic tinge.
- Power Limiter: The reason you see her chained up in Kahn's Arena, despite the fact that Kahn created her.
- Rags to Riches: In Skarlet's revised backstory, she was a starving street urchin whose willpower was so impressive that Shao Kahn taught her blood magic and raised her. Numerous Outworlders express their amazement at how far she's come from where she started.
- Rain of Blood: Skarlet's usual victory animation is her showering under, presumably, the defeated foe's blood. It is also one of her potential buffs within the game.
- Remember the New Guy?: Given that she appears as early as the MK1 portions of the story, she's at least a minor case of this.
- Retcon: Despite initially being written as a construct of blood Shao Kahn created, a slew of intro dialogues in Mortal Kombat 11 and her profile in the official site suggest Skarlet was a normal outworlder who was taught blood magic by Shao Khan after being impressed by her fighting spirit.
- Confirmed in MK11's story mode, where Kotal Khan refers to her as "the orphan-turned-assassin."
- Roaring Rampage of Revenge: Once Quan Chi's mind control wears off and she realizes what she has done by killing her master Shao Kahn, it is on.
- Screaming Warrior: She speaks as much as Reptile does in 9, yet seems to be as proficient as Liu Kang in terms of warcries. Averted in 11, where she speaks normally and has an overall calmer demeanor.
- She's Got Legs: Both of her outfits in 9 have her wear knee high boots that show off her legs.
- Ship Tease:
- Because Kotal Kahn knows Blood Magic like she does, she suggests that they "comingle their blood", which he rejects because he's already spoken for.
- She asks Sub-Zero to be trained by the Lin Kuei, which he rejects. And when he tries to dissuade her interest in his blood by stating that it runs cold, she becomes visibly excited.
- Sinister Scythe: A favored blood construct Skarlet uses during fights is a jagged scythe shaped from blood.
- Spy Catsuit: In the X prequel comics, she dons a black bodysuit upon allying with Reiko.
- Spell My Name with an "S": As is tradition with the series, her name is the word "Scarlet" spelled with a "K" in place of the "C".
- Even more than usual. Skarlet was based on Kitana's already scanty outfit, and then the design department started carving away at that. You could swallow her entire wardrobe with a glass of water. The whole thing is justified by the story as well (as making contact with blood is how she gains strength, she needs a lot of places for it to contact during battle).
- Averted in 11. She's fully covered in her default costume and even wears a head covering mask, with her other costumes also being pretty modest, with the most revealing of her outfit showing her cleavage at most.
- Suddenly Voiced: In MK11, she speaks after being silent in her first appearance.
- Uncertain Doom: Only her time displaced past self appears in 11, leaving it ambiguous as to what happened to her between the X comics and that game. Kotal Kahn mentions her as a long gone Outworld champion, so it seems like she's dead.
- Undying Loyalty: To Shao Kahn, as he raised her to have such. Unfortunately, this doesn't stop her from being mind controlled in her non-canon ending in which she kills him. In the Mortal Kombat X comics she is shown to give her allegiance to Reiko rather than Shao Kahn's designated heiress Mileena.
Skarlet: Souls hold more power than blood?
- One of her intros with Noob in 11 starkly proves that she values her power more than the one who bestowed it, to the point that her arcade ending sees her ascend to godhood with Shao Kahn grovelling at her feet.
Noob Saibot: Shao Kahn hides his best magic from you.
Skarlet: If true, he will die.
- Used to Be a Sweet Kid: According to Kitana during one of their intros. Skarlet brushes it off by saying the more innocent her was starving and weak.
- Vampiric Draining: A side effect of many of Skarlet's amplified special moves is restoring part of her own health pool by literally draining it from the opponent.
- What Happened to the Mouse?: In issue #26 ("Watch the Throne") of the Mortal Kombat X comics, she has her legs obliterated by Mileena and is about to be pummeled by her before she shifts her focus on Reiko. After the battle on the beach, Skarlet doesn't appear for the rest of the comics. In addition, she hasn't received any mention at all in the Mortal Kombat X game itself either, but she returns in Mortal Kombat 11.
- What the Hell Is That Accent?: Notable in that many of the other Outworld characters do not have accents. In 11, however, Skarlet speaks with a Polish accent.
- Voiced by: Terrence Carson (credited as T.C. Carson)An exclusive character for the PS3 and Vita versions of the game, Kratos is the main character of the God of War Series, making his second fighting game appearance since Soulcalibur: Broken Destiny.
- Badass Adorable: Usually when a Babality happens the victim usually does something funny, then realizing their failure throw a tantrum. What does Kratos do? Yank the head off of a Medusa plushie and display it proudly. Not only that but Baby Kratos still has his six pack and Badass Beard. Even as an infant he's still a BAMF.
- Bald of Awesome: Much like his home series, Kratos lacks hair on his scalp.
- Bloodier and Gorier: Compared to his Soulcalibur adaption, which was significantly Lighter and Softer. He's more gruesome here in line with his home series being filled with Gorn.
- Combat Pragmatist: Not above blinding his opponent with the head of Helios before attacking him.
- Defiant to the End: Born of Executive Meddling. Sony didn't want one of their most iconic badasses looking weak in the game, so Kratos is the only character who keeps up his menacing sneer even during X-Ray Attacks and Fatalities. He still makes the appropriate grunts and spits blood and such, though.
- Guest Fighter: From God of War. As the 1Up article said, this role could be the best fit for him. Kratos also has the honor of the being the first example of a guest character who has appeared in two separate fighting games thanks to his appearance in Soulcalibur: Broken Destiny.
- Lighter and Softer: As hard as it is to believe for someone like him, one of his two Fatalities is this game ("Medusa's Gaze") is downright tame compared to any other in this game. He uses Medusa's head to turn the victim to stone and then uses the Nemean Cestus to shatter the statue. No blood or gore in it at all. That's how petrification works in his series, so it is only Lighter and Softer here in Mortal Kombat.
- Quick Time Event: Incoporates these as part of his moveset in a nod to their usage in his home games.
- Throw the Dog a Bone: His arcade ending, where he becomes allies with Raiden and Fujin. Possibly the only time gods has shown him respect without being back stabbed. Kratos himself is taken aback by their friendliness, having rarely met a fellow deity who was genuinely kind to him.
- Truer to the Text: Soulcalibur: Broken Destiny had to Bowdlerize him due to the former being rated T. Here, Kratos gets to be as bloody gruesome as possible since Mortal Kombat 9 is a hard M. Additionally, the Quick Time Events were absent in the former.
- Version Exclusive Content: He's only available on Sony platforms, as you might expect.
- Weapon of Choice: He brings along an impressive arsenal from God of War III, including:
- Bow of Apollo: As one of his specials. The normal attack fires two, the enhanced attack fires three.
- Blade of Olympus: Involved in the "Blade of Olympus" fatality, and as the third hit of his enhanced Quick Time Event.
- Blades of Exile: His punches, also involved in the first hit of his X-Ray, as well as in his "Blade of Olympus" fatality.
- Head of Helios
- Nemean Cestus: Involved as the second hit of his X-Ray and in his "Medusa's Gaze" fatality.
- Medusa's Head: Involved in his "Medusa's Gaze" fatality.
Frederick Charles "Freddy" Krueger
- Voiced by: Robert EnglundA malevolent spirit of the Dream Realm, Freddy Krueger preys on the souls of the living as they sleep. When Shao Kahn began to steal Earthrealm's souls - souls Freddy considered his own - Freddy battled the emperor in the Dream Realm. But Shao Kahn's will was too strong. He pulled Freddy into the real world, where he was mortal, and defeated him. A badly injured yet determined Freddy fitted both his hands with demonically enhanced razor gloves. Once he has killed Shao Kahn he will find a way back to the Dream Realm, where he will torment Earthrealm's souls for eternity.
- Canon Welding: Notably, Freddy's inclusion tries to justify his existence in the context of the Mortal Kombat universe by stating his domain exists as one of the realms called the Dream Realm.
- Canon Immigrant: Not Freddy himself, but the Dream Realm is implied to be canon to the series with Tremor's ending in MKX, where it is stated he stole a psych bomb from there for use in Kano's theft of Shinnok's Amulet.
- Composite Character:
- This version of Freddy uses Jackie Earl Haley's likeness but pretty much all of his moves and fatalities are derived from Robert Englund's tenure as Freddy, in addition to being voiced by the man.
- On A related side note, the woman in his arcade ending, who is most likely Nancy Thompson/Holbrok uses Heather Langenkamp's likeness, but the bedroom she's in resembles the remake version.
- De-Power: Shao Kahn pulled Freddy into the real world to deprive him of his Dream Realm immortality.
- Downloadable Content: He was the fourth and final DLC character released for the game.
- Dual Wielding: After getting his ass kicked by Shao Kahn due to being deprived of his reality warping and immortality, Freddy arms himself with a pair of demonically-augmented gauntlets that bear a striking resemblance to his original glove but let him access his powers outside the Dream World.
- Evil Laugh: Two of his only voiced lines in the game are a sinister chuckle and a hearty laugh when he commits a fatality.
- Forced Sleep: A move allows him to rain dream dust on his opponents to put them to sleep and set up combos.
- Full-Name Basis: On the character selection screen, he's one of only four characters (the others being Johnny Cage, Liu Kang, and Kung Lao) whose full name is displayed and read by the announcer. During gameplay, however, his victories are only announced with "Freddy wins."
- Guest Fighter: From the Nightmare on Elm Street series. Notably, he's the first of five guest characters in the series to hail from horror films
- High-Pressure Blood: His first fatality involves him physically dragging his opponent into the dream realm, leaving only a fountain of blood where they once stood, just like in his debut film.
- Home Field Advantage: Subverted twice. Khan simply pulled him out of the Dream Realm and subjected him to a humiliating Curb-Stomp Battle in the real world, but then Freddy's ending shows him ultimately returning the favor on Khan's turf.
- Jump Scare: His Babality has the camera pan into the carriage to show a slash-marked teddy bear... and then baby Freddy attacks the camera.
- Murder by Cremation: Freddy has a fatality called "Welcome to my Nightmare". During this fatality, Freddy summons a large furnace. He then stabs the opponent in the neck and stomach, and chucks them straight into the furnace. As they burn in agony, Freddy waves goodbye and shuts the door, cutting their arm off, and burning them to death. This is a Shout-Out to A Nightmare on Elm Street 4: The Dream Master.
- Nice Job Breaking It, Hero!: In his ending, Nightwolf's attempt to seal him away so that he can no longer harm the people of Earthrealm only puts Freddy right back into the Dream Realm, the place he's most at home at, so he can continue his killing rampage.
- Nightmare Face: Covered in burns, as always.
- Silent Snarker: Played with; one of his attacks involves him telling his opponent, "Shhh."
- Shout-Out: All of his Fatalities and a lot of his moves are based on some of his most memorable kills in the movie franchise. His ending also features a recreation of his first movie's cover art.
- Wolverine Claws: Sports his signature clawed glove, now on both hands (due to the fact that it's hard to animate a character with claws on ''one'' hand in a fighting game).
