- Alma from the First Encounter Assault Recon games is this toward Beckett to the point that she repeatedly attempts to rape him, and at the end of the game, finally succeeds. What makes this worse is that she cannot understand why Beckett fights her off.
- Bloody Mary from Twisted Metal: Black. What's interesting is she doesn't have a specific love, but desperately wants a husband. And by desperate, I mean she stabbed her friend in the stomach on her friend's wedding day, then put on her wedding dress and kept it on for two years, bloodstains and all. She's in the contest to get her dream husband, but when he tells her he'll never love her (despite being lobotomized by Calypso), she goes Ax-Crazy on him, then drives into the sunset to look for her Mr. Right, "even if she has to go through each and every man, one at a time".
- Amy Rose from Sonic the Hedgehog was originally just a Clingy Jealous Girl to Sonic, but she is suffering Flanderization into this as of late, with Amy willing to Drop the Hammer if he doesn't reciprocate her advances. She seems to be back to normal in Sonic Lost World, though.
- Princess Sapphire Rhodonite from Disgaea 3 quickly takes a liking towards Almaz, Mao's
bitch "test subject." Almaz doesn't mind much, seeing as he's always had a crush on her (and because it's the only remotely good thing that happens to him), but let's just say she has very interesting ways of trying to help him out of his predicament. Fortunately, Almaz himself is usually safe from her violence-happy ideas. Usually.
Of course, I might've just gone back to slash you to pieces to vent my anger. You saved your own life. Heehee <3
- Occasionally, the fandom of Touhou portrays Alice as this, going beyond the usual Tsundere portrayal into seriously creepy territory. Highlights include attempting to put Marisa's soul into a doll to keep her forver.
- Then there's Flandre, who loves to "play" with Marisa. And Meiling. And Remilia. And anyone else she "likes", really.
- Koishi is this as well to a lesser extent, but more towards Satori and the character who defeats her in SA's Extra stage.
- Yuka Kazami is often portrayed as Yandere for flowers.
- Debatably the backstory for Parsee. The bridge princess youkai is the eternally-jealous spirit of a noblewoman who had a rather dire response to her husband's philandering, and was cursed into a demon for it.
- Gil from Harvest Moon Animal Parade (Japanese version) seems like this when you get him to a certain heart level.
"I want to lock you up in my basement and keep you all to myself."
- Gla DOS from Portal is an unusual case in that her primary goal is to chase Chell through a death maze and gets rather upset when she manages to escape. At the same time, she seems to have an unhealthy obsession with her captive.
- Wheatley from Portal 2 might count, especially in the Final Battle. All his ranting is him being angry about Chell apparently choosing GLaDOS over him.
- In Yoshine's route in Brass Restoration, Koutarou verges on this.
- Yoshine herself has some slight tendencies, doing things such as putting a threatening note in the front seat of the taxi to make sure her Ryo sits with her in the back, strapping him down in the nurse's office and undressing him while he asks her to stop, and attempting to drug and kidnapped him near the end of her route.
- Mad Father has two different brands: one romantic and the other parental.
- Aya's mother, who died before the game, made a Deal with the Devil to have her husband killed and be with her for all eternity. The real end reveals that this was a lie.
- Alfred, Aya's father, has this nature, especially in the real end. He planned to turn his daughter into a doll when she reached the right age. However, in order to achieve this, he killed his wife who wanted to save her daughter from such a fate. Once Aya finds out the truth, she's rightfully terrified of him and spends the rest of the game running from her Ax-Crazy father.
- The Updated Re-release of Yggdra Union has #367, a Shrinking Violet Extreme Doormat test subject, who's Cute and Psycho rather than a yandere. She's meek, submissive, shy, and uncertain... until the High Servant jacks her synchronization with her synthetic Diviner, putting her body and mind under intense stress. Instant Ax-Crazy. Truly, With Great Power Comes Great Insanity.
- Most of the games Charon makes has at least one Yandere.
- Yanderella revolves around the main character and two yandere girls. In both True Ends, the girl he doesn't choose will kill the girl he chose and, depending on which girl is the yandere, she may or may not kill him.
- Mikoto Nikki has a more tame yandere. She doesn't kill anyone that Matarou gets close to nor does she stalk him like other yanderes. However, she is mentally unstable and, if the player doesn't choose to hug her, will either kill him or keep him locked up for the rest of his life.
- Mix Ore presents Nagisa. Prior to the game, she stalked Kantarou for a quite some time and even "confessed" to him. When she peeked into his house one night, she saw him kissing his girlfriend. She suffered from a Sanity Slippage as she tried to process what she just saw. Her broken mind formulated a story about how she is Kantarou's girlfriend and Sanae is the Stalker with a Crush. She decides to kill Sanae and make Kantarou hers. However, Kantarou shielded her and was hit instead, resulting in him getting amnesia. On the fourth day, Nagisa finds Sanae and successfully kills her.
- Makoto Mobius implies that Mikio is this for Makoto. Think about it. She sends Watarou to save Makoto using the Mobius curse and he can't escape it unless he dies. In one bad end, when Watarou stabs Makoto, Mikio hits him over the head and declares that she won't live in a world without Makoto. She even goes as far as saying that she doesn't care who dies in Makoto's place. All that matters to her is Makoto living.
- Shihori Escape gives us a unique twist. Unlike her other games, the protagonist is the yandere this time. He was dating Shihori for a while, but one day, she decided to break up with him. It's never explained why she broke up with him, but this was enough to make Kitarou strangle her in rage.
- Really Ryez from Twinkle Star Sprites is yandere for Arthur Schmitt. Her favorite word is onore.
- Dark!Jaesa in the Sith Warrior class story in Star Wars: The Old Republic, if romanced, makes a hobby out of hunting down and murdering anyone the player character sleeps with.
- Holiday in the Consular path will shock Tharan's bed until he breaks up with the Consular.
- Persona 2 has Jun Kurosu. While it's not particularly touched upon in the main game, the drama CD turns him into an absolute psychopath over Tatsuya, to the point where even a friend having slightly better compatibility with him via horoscope is enough to send him into a meltdown. ...The creepy voice acting throughout the track (plus the humming and laughing) is enough to scare anyone for weeks.
- Persona 3: Mitsuru has a particular Stalker with a Crush with overt Yandere tendencies. This girl stands outside the assembly room for the Student Council (of which Mitsuru is president) all day, is obsessed with everything Mitsuru does, threatens to kill you if you don't cough up swimsuit pictures of her after the Beach Episode, and innocently asks if members of the Student Council would be replaced if... something were to happen to one of them. Oh, and upon learning Mitsuru rides a motorcycle, she says she would be thrilled to be run over by those "burning wheels of LOVE!"
- In Persona 4, there's an NPC outside the library who has a crush on an upperclassman. When she suspects that he has a girlfriend, she snaps at him and drives him away. Towards the end of the game, she places all the blame on the other girl and tries to kill her through indirect poisoning.
- In Persona 4 Golden, the unseen upperclassman's gender is changed to female and the NPC now suspects that she has a boyfriend. The NPC herself however remains female...
- Bioshock Infinite has the Songbird, whose sole purpose is to hunt down your partner Elizabeth and drag her back to imprisonment, out of programmed possessiveness. It's thirty-feet tall, and there's no way for you to kill it. Until you get to an ocean.
- Mithos of Tales of Symphonia probably counts- his love for his sister Martel drove him to attempt to eradicate the entirety of the human, elven, and half-elven races by turning them into sterile, immortal, and emotionless zombies because his sister was killed because of Fantastic Racism. He snaps when Martel is briefly revived and tells him that this isn't what she wanted, and tells him her last wish is for him to stop it- he misinterprets it as she and he are Too Good for This Sinful Earth and both worlds should be flat-out destroyed. If anybody tries to tell him he's wrong, or says anything that could even be severely twisted around as being bad about his sister, he will kill you. Damn.
- Dragon Quest VII has Kaya, a cheerful maid who's fallen in love with her rich employer's son, Iwan. Unfortunately, they're also caught up in a complex Love Dodecahedron... While Kaya initially comes off as the only one who isn't Wangsting and/or being an unhelpful Jerkass, instead working towards a solution, towards the end, she cracks a joke about poisoning everyone in town. While everyone is eating at a feast she prepared. Later on, you find out she wasn't joking about poisoning people, though she's narrowed her focus to a single target: her husband.
- Jin Kisaragi from Blazblue is another male example, and dangerously skirt with Cute and Psycho. Any moment he's mentioned about his brother Ragna the Bloodedge, he drops all his cool exterior and goes Ho Yay to the max 'Oh brother...~' and expresses his 'love' by trying to kill him. Then there's the final boss Nu-13, who is usually robotic with everyone else, but if she meets Ragna, she also becomes a crazed lovestruck and tried to have him and when Ragna refused, she attempts to kill him. Then you realize that Nu is based on Ragna and Jin's sister. God, it sucks to be Ragna!
- And when Nu and Jin meet, and Nu loses, well...
- And you think he's bad, wait until you see Jin's female Love Interest Tsubaki Yayoi. She's crazy about him, and not in a good way. She tries to kill her best friend Noel and Jin himself because she is led to believe that Noel stole away her chance to be with Jin. This case of Love Makes You Crazy eventually becomes a case of Love Makes You Evil, prompting her Face-Heel Turn after Hazama gets a "proper" hold of her. Also, in the Wheel Of Fortune story, when she sees Saya happily playing with a younger Jin, she goes batshit insane, screaming at her to get away from Jin. The thing is, she was presented as a fairly sane and level-headed person in Calamity Trigger.
- Happens in Mitadake High. Like one time where the Yandere turned out to be the killer. "If I can't have you no-one can" does not BEGIN to describe what happened.
- Catalina of Grand Theft Auto: San Andreas, particularly as she starts getting closer to C.J. As if she weren't already crazy enough.
- Sasha of inFAMOUS, the leader of the Reapers and the first Supervillain you fight is obsessed with Cole, whispering maniacal pleads for his love into his mind when he comes into contact with the sludge she controls. It might have something to do with the fact that she was Kessler's former lover and Cole is actually an Alternate Universe version of Kessler.
Why, Kessler? Why do you love her? I'll kill her, I swear it! I'll wear her skin like a robe!
- Nuwangi in Utawarerumono. Sure, he is also an arrogant jerkass, but most of what he does is out of either desire for Eruruw or wanting to destroy Hakuoro. It's hinted from time to time that if the situation weren't what it was he wouldn't be as much of an ass. He's definitely not happy about what happens to Tuskuru.
- In the Nancy Drew game Stay Tuned For Danger, the culprit is the rare male variety in the form of Dwayne Powers, whose motive for sending death threats to, and trying to kill, Rick Arlen comes directly from Rick dating the actress Dwayne is secretly in love with.
- Depending on the ending you get, Maria/Mary in Silent Hill 2. It doesn't get much more Yandere than going One-Winged Angel and becoming the Final Boss because the target of your obsession rejects you.
- James himself is most definitely overcome with love and more than a little unhinged.
- Rachel, in the Sci-Fi Chapter of Live A Live. She snaps after Kirk, her boyfriend, dies and she carries his body to her room and acts as if he is sleeping. It's easily one of the creepiest scenes in that chapter, let alone the game itself.
- In Pokémon Vietnamese Crystal, a very badly translated version of Pokemon Crystal Version, your rival seems to be a Yandere. Each of the player's encounters with him involves him berating the player, calling them things like "TRASHY" and "WEAK WORM", all while promising to beat them down. However, he also has a tendency to follow the player around and abruptly declare his love for them during his rants. It Makes Just as Much Sense in Context.
- The StarCraft novel series The Dark Templar Saga suggests a similar relationship with the protoss being Yandere towards the xel'naga. After the xel'naga abandoned them, the tribes engaged in the biggest civil war the galaxy had ever known, killing each other because each held the others responsible for driving the xel'naga away. Many also hated the xel'naga for abandoning them... No surprise these became the Scary Dogmatic Aliens of the setting.
- Irisu Syndrome!: Irisu Kyouko won't let anyone get in the way between her and her soulmate Ujishima. Especially not dirty thief cats.
- Kimmy Howell in No More Heroes 2: Desperate Struggle. She's a bit more up front than most Yandere, though; she's a Fangirl of the main character, and cheerfully explains in a love letter that she's going to make sure he never dates another woman by killing him and taking his head as a trophy.
- Mimmy is also this towards Henry, not allowing him to wake up so she can stay with him forever, even threatening to kill him when he suggests that they can live together in the real world. Since she is mostly a creation of Henry's mind, however, and technically not real, it is kind of obvious.
- Clara from Skies of Arcadia toward Gilder, though she is a very benign, Played for Laughs example.
- Shin Megami Tensei has Yuriko. She goes so far as to not just hunt down the supporting cast, but everyone else with her name, just so she can be with the Main Character. It does not work.
- As if that weren't creepy enough, Yuriko is also revealed to be Lilith, the Mother of Demons. She wants The Hero to sire a new race of demons with her.
- Say hello to Alice. Actually, she's not the real Alice. Her adoptive parents, the Count in Red and the Baron in Black, are actually Belial and Nebiros. Funny thing is, she's still mentally a young girl who wants to do normal things like go to school and get lots of friends. The problem is her "revival" gave her magic. Lots and lots of dark magic. Along with eroding her sense of why it's not a particularly good idea to torture, kill and eat your friends for fun.
- Lezard Valeth from Valkyrie Profile. When he first meet him, he kidnaps an elf girl who kill her and intertwine her genetic make-up with a human girl's to create a half-elf vessel for the main character, then uses his former teacher and her husband as bait by transforming the man into a monster and have him kill his wife. Then in the second game, he time travels and wreaks havoc with the timeline, kills so many people that it borders on genecide, and all just to get into Lenneth's panties.
- No question, he's completely insane. But there's absolutely no point that he genuinely appears nice faking it during Silmeria doesn't count. Stalker with a Crush to the Nth degree, but Yandere could be considered a stretch.
- Kingdom Hearts: Chain of Memories: Riku Replica goes absolutely apeshit if he thinks you'll get between him and Namine. Also, Marluxia's plan was to brainwash Sora into one of these for Namine, hereby turning him into a pawn to take over the Organization. It almost works, and after Sora and Riku Replica learn they were brainwashed, this doesn't affect their feelings much. (Namine ended up having to wipe Sora's memories of her to get him to recover.)
- While many characters in Rule of Rose fit the bill, no one suits the trope better than Wendy, who kills Jennifer's dog Brown because she thinks that she likes him more than her, and when Jennifer reacts badly, she trains the neighborhood psycho to murder everybody.
- Tira from Soul Calibur, Nightmare's very perky Dragon. She is a Psycho Supporter of his who explicitly wants to become one with Soul Edge, the Evil Weapon that the entire story revolves around. This gets a lampshade hung over it in the Gauntlet (a humorous, non-canon story from Broken Destiny, the PSP port of IV), where she functions as Nightmare's unwanted Stalker with a Crush and wants him to eat her and destroy the world, saying that she'll kill anyone who gets in the way of her love.
- A possible interpretation for Arvis of Velthomer, then Emperor Arvis of Grandbell from the Fire Emblem Jugdral games. Granted, he was already pretty fucked up from childhood due to being abandoned by his mother Cigyun when he was seven years old, but the scene towards the end of the first part in which he shows off his new wife Deirdre to her original husband Sigurd before pinning the crime of high treason on him and burning him to death with his Falaflame magical tome is pretty easy to interpretate as him being Yandere for her.
- In the second part of the game we have Prince Julius of Velthomer who happens to be Arvis and Deirdre's son. The only person he shows affection to is his girlfriend, the local Dark Magical Girl Ishtar, and when he finds out that her bodyguard Reinhardt seems to be a liiiiiiittle too close to her for his comfort, Julius forces Ishtar to fire him under the threat of killing him the next time he sees them together. To be fair, Julius has been the Soul Jar for the evil god Lopto for a while already when that happens, therefore we don't know if he's a Yandere per se or because of Lopto.
- Valter the Moonstone from Fire Emblem: The Sacred Stones is already Ax-Crazy, but his obsession with Princess Eirika places him squarely into this trope as well.
- Tharja from Fire Emblem Awakening epitomizes this. She follows the Avatar around everywhere (regardless of the Avatar's gender), counts how many times s/he turns over in their sleep and how many slices of fruit they peel, and has a lock of their hair in her bag, among others. You can also have the Avatar (if male) marry her if you so wish, which gets you this line from her Confession scene:
Tharja: I can't believe you made me love you! ...Course, if you back out, I'll murder you in your sleep.
[in his love confession to a girl!Avatar]: "I'll love you with every ounce of my blood, till I die. Ooh... when do you think that'll be?"
- Adele from Arc Rise Fantasia does not take the discovery that she was the hero's Unlucky Childhood Friend very well. She goes from a soft-spoken, shy, loyal White Magician Girl to the brash, sultry, manipulative high priestess of a Religion of Evil (a religion the hero was opposing, naturally) so fast, her neural pathways almost certainly have skid marks.
- Bowser from the Super Mario Bros. series games is actually this to Peach, which explains why he always kidnaps her in the first place.
- Both Catherine and Katherine are in love with Vincent, and Catherine outright states that she'll kill him or any girl he may be involved with.
- Planescape: Torment has one in Ravel Puzzlewell, who refuses to let her love leave her a second time when he comes to visit...
Ravel Puzzlewell: "I shall NOT let you leave — I have the power to KEEP you here, and I shall USE it. My black-barbed maze shall NOT allow you to travel beyond it while I LIVE, my precious, precious man..."
- Another male example is Anton Herzen from Professor Layton and the Diabolical Box. He waited years in a mansion for the return of his fiancée and when he finally sees someone who looks exactly like her (for good reason), he goes completely mad and tries to kill Layton because he thinks his long-awaited fiancée has been cheating on him. He got better, thankfully.
- Camos O. Laphroaig of the Hell Hounds in Galaxy Angel is a Yandere toward Milfeulle, he always calls her honey and somehow hopes his actions (including trying to shoot her down) will win her over. He finally croses over to true Yandere territory when he's taken over by the black moon.
- In Tales of the Abyss, Dist the Reaper is in the aftermath stage of this trope. As a child, he was clingy and obsessive over Jade, always wanting to remain at his side - when Jade finally rejected him once and for all, he became the raging, narcissistic person we see in the game, now obsessed with taking revenge on Jade instead.
- Tales of Legendia has a tragic example with Shirley, who for so long is actualyl a Love Martyr trying NOT to be a Yandere, and even after Senel rejects her love and she becomes Brainwashed and Crazy, she tries to hold on. But then Manipulative Bastard Maurits reveals a devastating truth about Senel that finally causes Shirley to snap and give into Nerifes' full control as means of revenge against Senel. She gets better, fortunately, when Senel apologizes and frees her from Nerifes later.
- The Boss from Saints Row: The Third can be one to Pierce, if you choose the Eastern European Female voice set. While probably not the jealous type (no one else is ever seen making a pass at Pierce, so it can't be said of whether or not she actually is) she frequently makes it clear that she has a thing for him, ranging from wondering if she can get cameras installed in his room, considering sending him a sex machine from "a secret admirer," offering to be his dominatrix, and finally admitting to wanting to make love to him in front of a live studio audience. If this doesn't seem crazy enough, this is the same woman who drove a tank out of the back of a crashing plane, parachuted into a penthouse party and immediately proceeded to kill everyone in sight, and has a murder record on her that runs into the thousands. In Pierce's position, it would most likely not be a good idea to even kindly ask his...admirer to back off.
- One sidequest from The Godfather 2 involves the questgiver asking Dominic to help snap his Yandere girlfriend out of it by force.
- Alois Racini from Amnesia: The Dark Descent expansion Justine, he is one of the suitors who after getting tortured and blinded by "beautiful" Justine keeps creeping around looking for her, wanting to kill her and keep her dead body with him forever.
- Mia Touma in her route of Duel Savior Destiny goes absolutely off the deep end starting with raping someone with drugs, attempting to petrify an ally, leaving that ally to die and finally outright switching sides to an Omnicidal Maniac faction out of jealousy.
- In Ib, Mary is obsessed with forming a friendship with Ib, displaying jealousy towards Garry and trying to ditch him a couple times, even at a point where it's clear he's in trouble and needs help. She tries to attack Ib when she thinks Ib will leave her. She chases after Ib and Garry with a palette knife. When she catches up to them she locks them in her toy box. If you anger her enough over the course of the game, she murders Garry. And in the ending "Welcome to the World of Guertena", Ib collapses in despair at seeing Garry go incurably insane and Mary decides the best solution is to keep Ib and Garry trapped in her world forever.
- In the social simulator H-Game Artificial Academy and its sequel, characters with the Evil trait will kill their partner rather than break up. A full list of their kill scenes is here (SFW link.) Character types 'Dark', 'Aloof' and 'Empress' have shades of yandere even in non-Evil comments.
- Mayu Sakuma from the THE iDOLM@STER: Cinderella Girls mobile card game. She stalks the Producer with religious zeal and catalogs his every move with GPS and camera photots. She also keeps track of the other 180+ idols... just in case...
- The RED Soldier from Team Fortress 2, who used to be the former roommate of the luckless magician Merasmus. After being thrown out of Meramus' apartment for being a lazy bum, trashing Merasmus' castle and getting the magician ejected from said castle by the authorities, and burning Merasmus' physical body after the angry magician transformed into a ghost form to attack the teams of mercenaries, the obsessive relationship turns into creepy homicidal stalker territory in "Ring of Fired", the first issue of Valve's latest six-part TF2 comic, when Soldier casually wanders into Merasmus' new apartment and snaps the neck of Tom Jones, Merasmus' new roommate.
Soldier: "The heart makes its own rules, Merasmus."
- Cia from Hyrule Warriors was originally motivated by love for Link and envy towards Zelda having his heart, but her garden and attacks firmly cement her as this. Aforementioned garden has statues of Link's various incarnations (yes, even the wolf), and some of her attacks allow her to summon Dark Link to assist her. And considering the events of the game were a result of her envy, it's safe to say she is too far gone for any therapy save a sword through the rack.
- Scharlachrot from Arcana Heart 3 is completely obsessed with Weiß. When you reach her in story mode, there are two possible scenarios what can happen: either Weiß doesn't show up, at which point Scharlachrot thinks that a world without her should be obliterated. If Weiß does show up, she gets mad for her not coming for her and wants to kill her and herself so that the two of them can be together in dead. This seems to be part of her brainwashing, as she drops this mindset once she snaps out of it.
- Yandere Simulator is a game currently under development that puts the player in the role of "Yandere-chan" whose goal is to get Senpai to notice her as well as eliminating all competition, either through blackmail, manipulation, or straight-up murder.
- Edda from Final Fantasy XIV starts out as an innocent, if somewhat ineffectual, NPC conjurer. Early in the story, her lack of healing skills and gladiator fiance's bullheadedness lead to her losing him. In later cutscenes, she seems determined to do something with her life (despite still carrying around his decapitated head). She eventually decides that the best way to use her life is to summon demons and use the souls of the damned (and the player's party) to create a new body for her deceased partner in the place where he died - Tam-Tara Deepcroft. All while giggling and sobbing uncontrollably.
