Woobie Destroyer Of Worlds / Anime and Manga

  • Both Celestin and Morgan Le-Fay from Ah! My Goddess The Movie.
  • Tetsuo from AKIRA, when he can no longer resist the urge to lash out and employ his full powers.
  • Anatolia Story has Nakia, who used to be a scared teenage girl whose father (the ruler of Babylon) ordered her to marry the king of Hattusa. Nakia was not happy about this, because Hattusa had invaded Babylon not so long ago, the marriage was blatantly using her as a political pawn, and the king was old enough to be her father. She goes through with it and ends up in a strange land, with a husband who has no interest in her at all. Lonely and angry, she ends up vowing to have a son and see to it that he becomes the next king, to ensure her bloodline continues to rule the land. By the time Yuri has arrived, Nakia occupies the second-most powerful position in the kingdom (which she achieved by poisoning Kail's mother) and is using every scheme she can think of to kill her stepsons and husband. As the series goes on, it's clear that she's willing to drive the entire land to ruin if it means getting what she wants, but she's completely and utterly alone the entire time, save for her right-hand man. Even her own son turns on her at the end, thanks to her insanity.
  • In Animal Land there are five humans who can understand all animal "cries" (animals can't understand each other so predators have no problems killing prey, and prey can't work together to even things out a little, and every night these humans have to hear shrieks of pain and terror). One of them wants to use ancient technology to kill every living creature on the planet because when he killed his own abusive father he saw how peaceful and redemptive dying was. He's also the only one who knows about religion but didn't utilize it to create a death cult, which would have probably been much more effective than suddenly trying to kill everyone without their permission. The surprise second woobie just hates the fact that they she, a clone of someone else, exist(s).
  • Berserk:
    • Guts, the Byronic Hero. He doesn't exactly want to destroy the world... but he is willing to walk a path of destruction to get to where he wants to be, and he doesn't care who gets in his way. Some say that Guts' quest to destroy the Godhand is suicidal and his seething hatred for the Apostles is just as horrific, and there might have been some truth to that before he got a call back to what was most important to him: protecting the woman that he loves, Casca. That's right. These two were unfortunate enough to have gone through the worst shit imaginable, and it will all end with both of them spending an eternity in hell thanks to their former friend making an epic Face–Heel Turn and sacrificing them and all of their other friends. The only way to spare him and Casca from this horrible fate in the smallest way possible? Kill every last one of The Legions of Hell by himself!
    • A very damaged soul is Rosine. Horribly mistreated by her cruel father, she mentally snapped from the abuse and accepted the Godhand's bargain, afterwards using her powers as an Apostle to lash out at the world. Even Guts who lives and breathes for the sake of revenge and sees Apostles (with good reason) as cockroaches, hesitates twice to finish her off, chastising himself that he will get himself killed if he continues. This means a lot coming from him.
  • Madam Red from Black Butler becomes "Jack the Ripper" to get back at prostitutes for aborting their children after she lost her own, with the help of Grell Sutcliff.
  • Bleach In the Fourth movie, Ichigo lets his Super-Powered Evil Side take over so that he can avenge the death of his sister, even though he nearly ends up creating Hell on Earth.
  • Chizuru Honda from Bokurano, after snapping due to her love interest and teacher's behavior towards her.
    • And now, in the manga, Jun Ushiro. HOLY GODDAMNED SHIT, USHIRO. What makes it worse is that it's not his world that he's messing with.
  • Code Geass either subverts or zigzags this, depending on how one views it, at the end. Lelouch, having lost everything, including Nunnally (apparently) and the trust of the Black Knights, abandons much of his reason and decides that he'll go down by finishing his quest to recreate the world. He played the role of an even worse Emperor than his father, from Geassing his soldiers into complete obedience and using them as cannon fodder, to ordering assassinations, and blowing up Mt. Fuji, depleting most of the world's sakuradite supply, in order to center the world's hatred around him and die a villain's death at the hands of Suzaku, who was disguised as Zero. Lelouch knew that there were other alternatives to Schneidel's scheme, which is one of the reasons it can be seen as a zigzagged trope.
  • Vincent from the Cowboy Bebop movie, having gone self-destructively homicidal from psychosis and the inability to separate his hallucinations from reality after becoming an unwilling participant in a Super Soldier program that caused him to permanently hallucinate. His leitmotif "is it real?" just hammers it home.
  • A lot of characters from Deadman Wonderland probably qualify, but the crown here definitely goes to Shiro/Wretched Egg. Despite the horrific things she does on screen, by the time her backstory is fully revealed (and good God is it tragic), even Ganta agrees that his worst enemy isn't nearly as much of a monster as he first thought.
  • Death Note
    • Teru Mikami was viciously bullied throughout his childhood so that when Light needs a new Dragon it's no surprise when Mikami gleefully accepts the titular Artifact of Doom and the duty to "eliminate evil." However, when Mikami gets a hold of the Death Note he takes it even farther than Light killing off people with criminal records and the lazy. (Light thinks it's "It's too early" to do that sort of thing.)
    • Misa Amane counts, as well. Her parents were murdered and she was about to be killed by the same person that murdered her parents had it not been for Gelus. No wonder she's become so psycho and a huge Kira supporter. It's even more sad when she's interrogated by the police and was asking them to kill her.
  • BlackWarGreymon from Digimon Adventure 02 wanted to destroy the Digital World because he thought that, that was the only way for him to understand his purpose in his artificial life and soothe his pain.
    • Yukio Oikawa from the same series. Growing up as a lonely boy in a unforgiving world, the only friend he ever had was Hiroki Hida, Cody Hida's father. During their youth, they became the very first humans ever to discover the Digital World, and they together promised that they would one day travel to it. Fate decided to be a mean bitch one day and killed off Hiroki during his line of duty as a police officer before it could happen, leaving Oikawa with no one else in the world but his promise. Depressed and lonely, he became a easy target for Myotismon's ghost to possess, who promised him that he would help him to get to the Digital World and fullfill his promise to Hiroki...at the expense of everything and everyone else.
  • Digimon Tamers has two characters Takato and Jeri go through this phase at different points as a result of the Heroic B.S.O.D. they both suffer when Leomon is killed. With no respawn point in this series. It's always the ones you least expect.
  • In Dog Days, the castle-crushing demon prophesized to kill our heroes is really a baby earth spirit, stabbed with an evil sword and forced to eat his mother and then kill everyone around him, until all he wants is death.
  • Broly from Dragon Ball Z is heavily implied to be this in the Eighth movie. The movie heavily implies that his destructive nature, even by Saiyan standards, as well as his overall insanity was the direct result of life-threatening factors from his birth, such as his nearly dying from a stab wound commissioned by King Vegeta simply because he feared his power level, and then having to witness Frieza destroy his home planet. Then his father places a slave crown on Broly and uses him to destroy several planets for his plan to get revenge on Vegeta for what his father attempted to do to Broly and himself.
  • Lucy from Elfen Lied. Several characters think that it's her natural instinct to eradicate humanity, but given her past, her experiences alone would be enough to make her what she is. She truly believes that she doing all those atrocities out of instinct, so if we look at the nurture aspect, we come to the conclusion that she Mind Raped herself (with a little help from nearly everyone around her and an inner voice / alternate personality that wants to eradicate all life) into believing that she was, in her own words, "born to wipe out mankind". Heartbreaking can't even begin to describe it.
  • Black Mage Zeref from Fairy Tail. Whatever spurred him to go and earn the reputation he has is a mystery, but he's so unbelievably miserable in the present that you just want to hug him. For the love of God, though, do not hug him! He gets even more Woobie when his motivation for creating all the demons and dark artifacts was simply him trying to find a way to bring his brother back to life.
    • Chapter 450, if that were even possible, manages to make him even more Woobie. He allows himself to believe that he can finally care about someone when he learns that Mavis suffers the same curse he does. Her kindness and desire to stand beside him so together, they could find a way to break the curse, or, if that weren't possible, cure each other's loneliness, is enough for him to fall in love with her. They kiss... but because Ankhseram is so intent on destroying any chance of him having happiness, his love for her is enough to break her curse and kill her, or at least, kill her body. It was this event that broke Zeref and turned him evil.
  • ToyMajin of the Fresh Pretty Cure! movie. He was tossed away by his previous human owner and he was filled so much bitter anger, he decided to steal away all toys, then use them to power himself, many of them filled with that same anger. When he captures Usapyon, Love's precious toy bunny doll, it breaks the Cure, making her think that she had the same hatred and drives her to try to make amends... only to find out she never hated her at all. Thanks to the children's love for their toys, Love's able to get ToyMajin to see the error of his ways and sees his true self... a teddy bear. Which she promptly gives to another kid who promises to take care of him.
  • Fruits Basket: whether or not one can excuse his or her actions, Akito counts. Despite beating the living daylights out of several Zodiac members for the majority of their childhood(s) and emotionally abusing everyone, Tohru can't help but feel sorry for him or her. One, she learned just how badly Akito herself was emotionally abused, and how her upbringing influenced her outlook on life. The psychological abuse heaped onto her by her mother and Evil Matriarch extraordinaire, Ren, led to a pathological fear of abandonment, driving her to do anything to make sure no one will leave her. Being told that no one loves you, everyone will abandon you, and no one even respects you, and having your boyfriend sleep with Ren to spite you for sleeping with another man (which you partly did to get back at said boyfriend, and partly to stop said man from abandoning you) will do that to you.
  • Scar from Fullmetal Alchemist is one of the few survivors of a brutal genocide which killed almost all his loved ones. As revenge against the government who massacred his people, he becomes a Serial Killer who exclusively targets state alchemists. Fortunately, in both manga and both animes, he gets better.
  • Yomi from Ga-Rei -Zero-. She was not exactly powerless before she become a rampaging monstrosity, but events conspire to bring her down from her height and kick her mercilessly while she's down.
  • Elaine and Diana, the two unbelievably powerful psychic sisters, in Genocyber, who both go through some truly nightmarish crap before transforming into the eponymous Anthropomorphic Personification of destruction, Genocyber. Then they proceed to wipe out Hong Kong, then every single city in the world, then the only post-apocalyptic city that remains. Or maybe not...
  • Brandon Heat, or, more accurately, Beyond the Grave, from Gungrave. A nigh-unkillable, unstoppable killing machine capable of destroying armies of super-powered zombies single-handedly with more firepower than some developed nations, by the time he becomes Beyond the Grave, he has forsaken the love of his life because he thought that she deserved better than to be with a ruthless hitman, watched his boss, who was the father he never had, marry her, and been killed by his best friend (he got better) and resurrected by the daughter of his former lover to protect her. He does this by killing all of his friends, including his best friend and his mentor.
  • Haruhi Suzumiya: After going through nearly 15 and a half thousand of the same 2 weeks, Yuki gains emotions and becomes this. Except that she doesn't destroy the world. She steals Haruhi's powers and RetCons reality for 1 year, according to the novels, and 3 years and 5 months, according to The Movie. And she succeeds. And she's stopped by the protagonists. And, for a point in time, there's 4 Kyons and 3 Mikurus.
  • Depending on how you view his character, Alucard of Hellsing may qualify as this. If you look through the axe-craziness, he seems like quite the Death Seeker. Then there's his Dark and Troubled Past...
  • Takano Miyo from Higurashi: When They Cry...Ironically, though, she's aiming at the wrong target in order to become a god. Guess Tokyo's a little too big to take down single-handedly.
  • Yuuhi from The Lucifer and Biscuit Hammer, with a Freudian Excuse to match: his father, a detective, was killed by his colleague. After the funeral, his mom simply left, and his grandfather beat into him the idea "Make no enemies - they'll stab you in the front; make no friends - they'll stab you in the back." Sami's reasoning is that she wants to own the world by destroying it so that it doesn't go on without her when she dies.
  • At the end of Magical Girl Lyrical Nanoha A's:
    • Hayate Yagami became one, though it required a massive Break the Cutie moment created by other parties to push her past the "the-world-has-hurt-me-so-much-it-deserves-to-die" breaking point, and when she regained her senses, she chastised her Artifact of Doom for thinking that that's what she really wanted and put a stop to things.
    • The Book of Darkness is a woobie because she's a destroyer of worlds. Her life cycle has three phases: charging up in dormancy, gaining full awareness and control for a few minutes, and then dishing out an Earth-Shattering Kaboom, which returns her to stage one. Prior to her current appearance, she has been forced to serve a cruel master who abused her children. Bonus points for the fact that there is nothing that can be done to stop the cycle.
    • Another one in Magical Record Lyrical Nanoha Force: the Huckebein family seems become this. Sure, they have to try to find a way so they could control their Eclipse disease. But their unsympathetic actions, like slaughtering entire villages and communities, massacring the innocent people who had nothing to do with their affair is not a justifications for their reason to survive.
    • And Admiral Gil Graham in A's, who set the whole thing up in order to seal the Book of Darkness when it awoke. That Hayate would be collateral damage was unfortunate but unavoidable in his mind. Nobody judges him too harshly for this, because, honestly, no one else had come up with a better plan for stopping the Book.
  • The Mazinger saga has two of these:
    • Dr. Hell in the original Mazinger Z manga. Everyone (including his parents. In particular his mother 'repeatedly' complained she never wanted having him, and hit him for any reason) abused him and mistreated him during his childhood and teenhood years until his mind finally snapped out, and he decided one day he would purge the world off idiots, and everybody would have to bow down to him. He was still dreaming of doing just that several decades later when he finally found the means to do so as exploring the ruins of an ancient, lost civilization.
    • In the Darker and Edgier reboot Shin Mazinger Zero, Koji Kabuto himself became this as he literally lost everything in the first chapters. To wit: his father was murdered, his girlfriend was raped AND killed, he killed the culprit (his grandfather, of all people), lost an arm... and then not only he became this trope, but he and Mazinger ended up literally destroying Earth. And for worse, a Robot Girl named Minerva-X witnessed everything and couldn't do anything to help but pressing a Reset Button. Then he found himself back to his supposedly normal world as a result of said Reset Button use, unable to properly remember what happened, until Minerva showed up as a supposed New Transfer Student, determined to help him avert this trope so the planet won't be destroyed again.
  • Rau Le Creuset from Mobile Suit Gundam SEED. He's a dying man at 28 years old, born with telomeres of the thirty-something Al Da Flaga, his genetic "father". He's in constant pain that can only be subdued by drug dosages that double twice over the course of the series. His dealings with people, hatred of his flawed body and the people who ensured that he was born that way, his emotional pain over his Parental Abandonment, and being a clone and thus seeing himself with no "identity" of his own eventually became a bitterness towards humanity in general. He descends into full Nietzsche Wannabe territory, convinced that humans only inflict pain and suffering on others, not least of all himself. Aware that his own existence cannot be considered human and is more or less the personification of mankind's sins, he took it upon himself to be the Judge, Jury, and Executioner of humanity, and in a very literal bid to make the pain stop, he tried to Kill All Humans, and nearly succeeded.
    • By the time he sentenced all of humanity to annihilation, he was more or less reveling in the fact that his view was "vindicated" by the actions of Murata Azrael, who had just tried to wipe out all Coordinators with a nuclear missile array, and Patrick Zala, who was preparing to annihilate all life on earth with GENESIS. A life or two was meaningless at this point.
    • And an example from its sequel is Stella — she stomps through city and wilderness alike in a giant robot, slaughtering innocent bystanders by the thousands because she's driven by a childlike, irrational terror of death, and has been told that if she doesn't fight, scary things will kill her and everyone she cares about. The fact that she's just being used by Neo and Djibril, who are deliberately playing on her fear and pain, makes this all the sadder.
  • Lord Fezarl Ezelcart, the Big Bad of Mobile Suit Gundam Age, is a married man and was a father. However, the death of his son convinced him that it was high time to root out the weak by waging a war that would eliminate them and create a paradise populated only by the most righteous of humans. Thus began the UE's attacks on Earth Federation Colonies. In the third generation, note , fate really twists the knife by having him encounter a young boy who greatly resembles his son... Who just so happens to be a Federation pilot and the grandson of Flit Asuno, main hero of the first generation and the biggest Vagan-hater alive. Ezelcant's son, in his last moments, said that he'd like to be reborn on earth along with them. Ezelcant is convinced that his son got half his wish.
  • Enchu in Muhyo and Roji, as it's revealed late in the series that the real reason he turned to evil was not out of hatred for Muhyo, but a desire for release from his pain. Some of his accomplices, including Rio and the Cortlaw Siblings are spurred on by the loss of loved ones, including the desire to return them from the dead.
  • Hiroko "Hiro-chan" Kaizuka from Narutaru is an intelligent, modest young girl who is broken by abuse from both unbelievably sadistic bullies and overly demanding, repressive parents. Eventually, she, along with her Shadow Dragon, Oni, attempts to make everything she doesn't like disappear...by way of going on a horrific, murderous rampage.
    • A similar thing happens to the main character, Shiina, but with someone else doing the destroying, right at the end of the manga.
  • Naruto
    • Gaara started out as this. He's lucky Naruto is a Warrior Therapist. For that matter, any jinchuriki (such as Naruto and Gaara themselves) is prone to be so.
    • The Nine-Tailed Demon Fox's escape plan is to turn Naruto into one of these.
      • It turns out the tailed beasts themselves are this. All were created by the Sage of the Six Paths, who treated them like his children. Once released upon the world, they were treated as feral abominations (and in the case of Kurama, the embodiment of hatred) only worth pursuing for their immense power.
    • In Part II, Sasuke Uchiha becomes this after hearing the truth about the Uchiha massacre.
    • Nagato. In a Serial Escalation of Deus Angst Machina, he snapped and became perhaps the most powerful Well-Intentioned Extremist around. He nuked the Leaf Village, killed many main characters among other atrocious acts. Don't mess with someone who just went through the wringer and is very close to justifying his God complex.
    • The biggest example is Tobi. He watched his only love die and the hands of his best friend, and at that point, he resolved to destroy the world and remake it in his image, or maybe Madara's image, it's hard to tell the difference anymore. In the span of a few months, he went from saying that those who betray their comrades are worse than trash to holding his sensei's newborn son hostage, killing his sensei and his sensei's wife, nearly annihilating his entire village and when his sensei's dying act thwarted his efforts, he plotted the extermination of his own clan. Nagato unleashed his woobie-induced rage on his enemies; Tobi unleashed it on his friends!
      • It doesn't help that Tobi is genetically prone to being a Woobie, Destroyer of Worlds.
  • Neon Genesis Evangelion: Shinji Ikari turns into this during End Of Evangelion. After spending the entire series watching/hearing most of the friends he made die in the most horrifying ways, then having to accept that maybe he would never get a normal relationship with his father, then having to decide to continue piloting the EVA for the world's sake, then having to kill someone who showed love for him, then have to see the girl that he loved had been chopped into pieces maybe it was a mistake to let him decide what will happen to mankind.
  • The eponymous Big Bad from Noein is this. It is revealed that he is a possible future of the male lead, who, upon losing his true love in a car crash, started desperately searching the time streams for a way to save her. Unfortunately, he found the multiverse to be full of pain and suffering, and decided to destroy everything and start it over from scratch.
  • Pandora Hearts: Vincent Nightray. Sociopathic Ax-Crazy Yandere with a brother complex and one of the most fucked-up backstories ever.
  • Pokémon: The First Movie: Mewtwo's motivations for wanting to conquer the planet in the first movie become a lot more understandable when one remembers his childhood, when his only friend disappeared without explaining why he was there and, in the height of his angst, his memories were forcibly erased. Even after his birth, he was taken advantage of by Giovanni until he'd had enough.
    • Similarly, Moe/Molly from the third movie is a lonely little girl whose mother is long gone and her father is sucked into the Unown dimension. As she cracks under the pressure, the Unown try to make little Molly's wishes come true and transform the mansion into a crystal palace, finally creating an Entei as Molly's father. Said Entei happens to be loyal to Molly to an insane level, kidnapping Ash's mother Delia to make her Molly's mom. And then the Unown's powers start going haywire...
  • In Puella Magi Madoka Magica, Kaname Madoka has been this for a few alternate timelines. She's The Woobie in all of them, because of nearly every event in the course of the show, but in any timeline where she survives Walpurgis Night as a Magical Girl (i.e. all of them so far where she hasn't died during it), she's fated to become an extremely powerful witch, and either has to be Mercy Killed by Homura or simply goes on to destroy the world whilst Homura goes back in time to try and fix things (again). In the final episode, she becomes this yet again but sacrifices herself in the process.
    • This was actually invoked by Homura in the third timeline. The two of them have beaten Walpurgis Night, but their Soul Gems are almost completely darkened. Homura's resigned herself to the two becoming witches and destroying the world. Madoka disagrees.
    • To some extent, Witches in general qualify. A Witch is made when a magical girl lets The Corruption take over her soul gem, transforming it into a grief seed. This usually happens when they cross the Despair Event Horizon. Now remember how many times characters are put into danger or outright killed because of Witches.
    • Puella Magi Madoka Magica the Movie: Rebellion: Homura finally succumbs to this crossed with Nietzsche Wannabe. We see that she resented Madoka's aforementioned sacrifice, and her Witch form finally emerges. When Goddess!Madoka comes to take her to "heaven", Homura fully becomes this: she then steals her powers and returns Madoka to human form, at the cost of herself becoming the Satanic Archetype to Madoka's Messianic Archetype and eventually having to become her enemy. She then places the entire universe under her control, and maintains the illusion by wiping everyone's memories. And yet...she still feels grief-stricken over the prospect of possibly becoming the series' Final Boss, and is ultimately trapped in a Self-Inflicted Hell.
  • Despite being destined to destroy everything, Ashura's true self in RG Veda might as well be one of these. His whole race was eradicated, his own mother disowned him and tried to kill him when he was just a few hours old, whenever people see him, it's either to declare him a "cursed child" and try to kill him or be nice to him and die themselves to protect him from his pursuers. Even the prophesy supports this: the prophecy says that "the red lotus flame would destroy all evil"; Ashura has power over flames and the fact that he would destroy everything he considers evil heavily implies that, despite his usual idealistic self, Ashura holds great hatred for the world that has been so cruel and unfair to him just for being born as an Ashura and really wants to see it burn. Only his love towards Yasha, the only one who loved him to the point of sacrificing a lot for him, was stronger than his hatred and omnicidal nature.
  • Sailor Moon:
    • Invoked by Wiseman, who Mind Rapes and forces a Plot-Relevant Age-Up on Chibi-Usa to make her believe she has been abandoned by everyone who loved her, thus making her The Dragon and his most loyal follower — the Black Lady. It works for a while, but she's freed from this in the end by Sailor Moon and reverts to her original self.
    • People under the influence of the Kisenian Flower in Sailor Moon become this. The Kisenian Flower specifically targets people with weak hearts, feeds off their negative energy, then destroys the planet they reside on and waits on the fragments until they find another willing host.
    • Hotaru. Woobie? Easily the biggest in the series. Capable of destroying the planet and everyone on it? You bet.
  • Homura from Saiyuki: sure, he wants to bring an end to everything in existance, but he's so sweet and vulnerable, and so many undeservedly terrible things have happened to him. His two henchmen fit this trope, too!
    • Goku. If it weren't for the merciful goddess replacing his broken power limiter when he did he would have killed Rikudo for almost killing Sanzo before Sanzo ever had a chance and before this he goes from adorable little boy to killing machine once his power limiter breaks and he kills hundreds of people upon witnessing his best friend (And only one his age) commit suicide so close that his blood get on him, all so that way he would not be forced to kill Goku and used as a pawn in his "father's" plans anymore. Then later when it breaks again from his overwhelming fear of being alone again and the monks chasing him in the temple just days after Sanzo saved him from the cave he was trapped in for 500 years.
  • Hao/Zeke Asakura in the Shaman King manga. Not so much in the anime, since he turns his Ax-Crazy factor Up to Eleven during the finale, which, sadly, is a Gecko Ending.
  • Valgaav from The Slayers TRY. A tormented half-demon dragon who believes that all cosmic forces in his world are caught in an endless, senseless war that only causes suffering, and wants to erase everything from existence to end this.
  • Kanto from Soil New Town has had a rough life his dentist drugged and raped him as a child which caused him to feel so ashamed and, well, soiled that he cut himself; it got worse when the dentist reconnected with him in high school and, as proof of his twisted "pure" love, gave him the video of his assault. The shame intensified to the point where he couldn't stand to watch cats in heat and tried to burn down the resident homeless crazy cat lady's shelter (fortunately, he didn't succed). Things seemed to get a little better when he met a nice girl, but just as he was about to have his first consensual sexual encounter, she disappeared from between his legs. No wonder he wants to destroy the world by enlisting the dentist's roughly three dozen unwitting current victims plus a victim by proxy (her rapists were also the dentist's victims) to cause enough anomalies to break reality.
  • Crona of Soul Eater has the 'destroy everything' part, by way of 'hir' reasoning that everything that s/he fears/threatens hir should be destroyed (for much of the series, s/he understands no other way of 'dealing' with it). Given that Medusa did and still does possibly intend to turn Crona into an Eldritch Abomination in the style of madness incarnate Asura, s/he could feasibly go all the way on this one. Until Our Heroes inevitably defeat hir.
    • In the manga, Crona is the Big Bad despite being a favorite character of the audience and cast. Crona ultimately takes all that potentially destructive power of becoming a Humanoid Abomination like Asura, and consciously uses it to imprison Asura on the moon, even at the price of Crona's own freedom.
  • Choji Suitengu, the Big Bad of Speed Grapher. His ultimate goal is to die after destroying the corrupted culture of greed that Japan had become, as they forced him and his sister into a living hell.
  • Mantid from Spider Riders — he loses the love of his life in war; it's implied that he lost many friends the same way; now this is just speculation, but it may be that he lost his spider partner as well, which makes sense because we never get to see it. With all that, it's no wonder the guy went off the deep end.
  • In Tokyo Ghoul, there are several of these running around.
    • The One-Eyed Owl aka Eto, the only known case of a natural Half-Human Hybrid and a Living MacGuffin. The product of Star-Crossed Lovers, her Ghoul father was forced by his superiors to kill her human mother shortly after her birth. In order to protect her from his superiors, Yoshimura was forced to abandon his infant daughter in the 24th Ward. Forced to kill and cannibalize other Ghouls to survive, she mutated into a Kakuja at a young age and began launching attacks against the CCG. Her father blames himself for his beloved daughter growing to hate the world, and pleads with Kaneki to find some way to save her from herself. As Sasaki, he explains that her novels reveal an author that has suffered greatly, completely giving up on being loved and unable to trust people. She frequently muses on the subject of love, while making it clear she believes it is merely something that destroys or controls people. Suffice to say, while the greatest threat in the series, the Owl is an enormous ball of anger and pain that wants to destroy everything as a result of a lifetime of suffering and loneliness.
    • In the sequel, Seidou Takizawa has become one. Even while slaughtering his way through Investigators, and torturing Sasaki while giving him a Breaking Speech......it's painfully obvious that his actions are a result of the physical and psychological torture he's endured for years on end.
  • Tri Peace: Picture if you will, a country of Perfect Pacifist People: no violence, no strife, no weapons — and no defenses. Add one devastating war and then:
    Formerly peace-loving anti-war Amnesiac Hero Nana: IT IS TIME TO MAKE THE WORLD PAY FOR ALL THE SUFFERING THEY'VE PUT US THROUGH.
  • Trigun features Legato Bluesummers, The Dragon to Millions Knives. He's got a sympathetic backstory as a nameless sex slave and, like Knives, has let his own pain drive him into becoming an Omnicidal Maniac. Problem is, he's an utter, sadistic psycho with a murder habit, who likes to torture the lead, reducing any sympathy factor for him both in-universe and out.
  • It is very possible to see Bernkastel from Umineko: When They Cry as this, considering that she is an amalgamation of all of the Rikas who died in Higurashi: When They Cry. Given the fact that all of these Rikas experienced several hundred years worth of A Fate Worse Than Death, it is unsurprising that their embodiment has some serious mental damage.
  • Video Girl Mai becomes this in Video Girl Ai, after ending up as a Sex Slave to a boy without a pure heart and going mad as a result.
  • Darcia from Wolf's Rain, who, after the loss of his lover, Hamona, turns insane and decides to ruin the paradise the protagonists are trying to create. In a sense, he doesn't want to destroy the current world, as the Earth is dying anyway, but prevent the next.
  • At the end of Fushigi Yuugi, Tamahome unintentionally has a Psychic Link to Nakago's mind revealing his past when he was a young boy, his entire tribe was wiped out, he witnessed his mother being gang-raped, and accidentally killed both his mother and her rapists with his awakened power, only to be sent to the Emperor of Kutou, who raped him repeatedly. As a result, he wants revenge on existence itself for giving him such a horrible life.
  • Russia of Axis Powers Hetalia is more of a Woobie Conquerer of Worlds, insisting that "all will become one with Russia". This trope is also played straight with him during the Bloody Sunday strip, in which he snaps and starts to mow down his own people on the grounds that "they're not really Russians if they don't love me".
  • Lucia of Rave Master has been portrayed as virtually a Jerkass extraordinaire, contradicting any even mildly humane moment shortly afterward. Until the ending, that is, when he starts crying while fighting Haru because, as it turns out, the universe exists to screw him over. He even lists all the massive wrongs done to him that no one ever did anything about, or even commended rather than tried to stop. Though he looks a little crazier than he actually is in that image. It applies to him much better when he's a child.
  • Diva from Blood+ may count, although the "Destroyer of Worlds" part only comes about simply because she exists. Chevaliers may love their 'queens' but it seems that Amshel loves power more. Diva went along out of embitterment with the world due to her imprisonment as a child. All that could've been avoided had Nathan simply abducted her and made her a star singer without the whole Take Over the World thing and "make everyone into Chiropterans" aspect of Amshel's and James' agenda. She drops the Woobie part after what she does to Saya's little brother, however.
  • Yuca from Immortal Rain doesn't know how old he is. All he knows is that, whenever he dies, he's reborn long after everyone he knew before died, while still retaining the memories of each of his previous lives. Over and over again, throughout what seems to be the course of human history. By the point we meet him, he wants to wipe out all humanity just so he can finally die and be able to stay dead.
  • Shinobu Sensui of YuYu Hakusho began as a heroic spirit detective, but had a mental breakdown after discovering humans torturing demons, throwing his life's work of protecting humans into question — one that isn't helped by his subscription to Black and White Morality. His mind, now fractured into seven split personalities, embarked on a plan to destroy humanity as a way of ending the confusion and guilt, along with a Suicidal Cosmic Temper Tantrum over his terminal illness.
  • Tsubaki of Future Diary was imprisoned as a sex slave by a cult her whole life before receiving her Diary, and now participates in the Diary game with the stated goal of destroying the world.
    • Yuno wants to keep the universe in an eternal time loop, forever replaying the Diary game, as this is the only way she believes she can stay with Yukiteru. She wants this so desperately because Yuki is probably one of the only kind people in her life, and her sole reason for living.
  • Tima of Osamu Tezuka's Metropolis. After getting shot and realizing that she's a robot, she takes control of immeasurably powerful technology and orders the extinction of humanity.
  • Yami Atem from Yu-Gi-Oh! becomes this for a bit in the Doma saga after he loses Yugi - especially during his duel with Haga. Oh, silly Haga, didn't you know that pretending to destroy the soul of a highly protective and emotionally unstable (and once-Axe Crazy) ancient spirit's partner was just asking for a one-way ticket down extreme-pain-and-death lane?
    • Thief King Bakura might count, given that he became what he was later because he survived and witnessed the gruesome killing of all the people in his village. Granted, they seemed to be a village of thieves, but still, he was an innocent child before this happened.
    • Malik Ishtar became cynical and evil from his father's abuse of him including a painful tattoo covering his whole back and that's not getting into his alter ego.
    • Pegasus became this after losing his wife and having his left eye forcibly replaced with a Millennium Item.
    • Diva/ Aigami from the "Dark Side of Dimensions" movie continuity certainly qualifies; literately having the ability to rearrange other dimensions and kill people in them. As a child, he and his sister lived with an abusive and neglectful man in Egypt, Until Shadi adopted them and cared for them alongside a bunch of other kids. They were taught all about the Pharaoh and told that when he returned to this world and left again for good, they would all be able to enter a portal to a better world. One day, [[spoilers: Ryo Bakura's]] father found the crypt and wanted to buy the millennium ring. Upon being tested,[[spoilers: Yami Bakura killed him. When Bakura ran to his father from his hiding place, the spirit of the ring bonded to him and possessed him.]]Diva was given some of Shadi'spowers and his magic cube before he saw his mentor killed in front of him, along with all the other kids, leaving him and his sister as the sole survivors. After this, he developed quite the hate complex; wanting to not only kill Bakura, but Yugi Mouto and Seto Kaiba as well, as he blames the pharaoh and priest Seto, who the two are reincarnations of,for the existence of the millennium items.
  • Izayoi Aki from Yu-Gi-Oh! 5D's for episodes 40 and 41. After watching her friend and mentor Divine plunge to his horrifying death, while the only place she'd ever really felt at home in collapses in flames around her, she wakes up from a coma where she relived every single horrible moment of her life all at once to the face of Yuusei, who she already feels conflicted about - and her parents, of all people. Destroying the world from there, though, yes, seems like Disproportionate Retribution, is not that much of a stretch.
    • Aporia, ZONE, Antinomy, and Paradox, especially Aporia, too.
  • In Anti-Magic Academy: The 35th Test Platoon Kiseki Kusanagi's powers drive her mad sending her on two omnicidal rampages.
