Elfen Lied/YMMV


 * Adaptation Displacement: At least in the U.S., what with the manga not being licensed there.
 * Alternative Character Interpretation: Practically every single character is left slightly insane from their troubled pasts, or completely evil. Often it's very hard to keep them apart.
 * Broken Base: Oh, God, the Fan Dumb. Oh, God, the Hate Dumb. The sane part of the audience probably won't make 50%.
 * Creepy Awesome: Lucy and Mariko.
 * Complete Monster:
 * Director Kakuzawa was the head of the research facility that experimented on the Diclonii. Kakuzawa was defined by his extreme hatred of humanity, and his wishing to become a god. In order for this to happen, he had planned on having Lucy mate with her half-brother, the result of his rape of her mother and having offspring through her. He would then use said offspring to wipe out the entire human race, and he would ultimately recreate the world in his own image, thus becoming a god. It's also shown that he commits several vile acts on his fellow man and is extremely callous to the suffering that he throws onto them. He's also shown as being a terrible parent to his children. He was shown expressing apathy over the death of his eldest son, and he also sees nothing wrong with using his children to extend his goals, as noted above with his younger son. While Kakuzawa does arguably show affection for his daughter, Anna, to the point of having ensured her survival from the experiment he turned her into back in the day, it's ultimately shown that he's so far gone and inhumane in the present day that he views her as a prized experiment and nothing more.
 * The Unknown Man from the manga is indisputably one of these. In order to find our protagonist, he crafted a radar system made from a silpelit who was still alive. In order to make sure that she wouldn't use her powers against him, he also built a tank for her which would keep her in a constant state of excruciating pain. He also felt it would be a shame to let said diclonius' body go to waste, so he, in no grey terms, raped her. Finally, just when you think this guy couldn't get any more repulsive, he attempts to rape Mayu. Because this man proves to be the embodiment of humankind's most monstrous nature, when Lucy kills him by unceremoniously tearing him in half}}, it's quite satisfying to see.
 * Mayu's Stepfather is a child molester who loved to sexually humiliate her, and it's shown that he went so far as to sodomise her. He gets no comeuppance for this, as it's only shown in a flashback.
 * Tomoo, the ringleader of the kids who killed Lucy's puppy, is portrayed as a complete and utter sociopath. He was a racist against the "inhuman" Lucy for no valid reason, enjoyed physically and psychologically hurting others more than anything, and was shown to have no redeeming qualities whatsoever, visibly getting a thrill out of beating an innocent puppy to death, and he drew it out as long as possible not simply to torture Lucy, but because he was enjoying killing another living creature so damn much. While it's debatable if the other children deserved to be massacred by Lucy afterwards, Tomoo most definitely got what was coming to him.
 * While Nyu is the definition of Helpless Good Side and Lucy (Or rather ) is an Anti-Villain and very Ax Crazy Woobie, Destroyer of Worlds,
 * Crowning Music of Awesome: "Lilium", the opening theme.
 * Cult Classic: In Japan at least. In America it's one of the most well-known anime series, being called one of the "classics" by several people.
 * Die for Our Ship: Yuka gets this alot.
 * The Lucy hatedom gets pretty rabid too, but how much of this is Die for Our Ship and how much is simply hating Lucy because she's a villain is completely impossible to determine.
 * Dude, Not Funny: A good measure of the humor in the first couple episodes involves Nyu acting like a toddler, wandering around naked and acting ragingly stupid.
 * Ear Worm: The opening is probably one of the biggest Ear Worms in anime history.
 * Esoteric Happy Ending: The final chapter of the manga clearly states that
 * Evil Is Sexy: Lucy drops Nyu's particular type of Moe, but turns into a deep-voiced Badass Hot Amazon Tsundere with major Woobie credentials.
 * Fanon: The Unknown Man is a Kakuzawa and thus is related to the Director. They do know each other, and the Unknown man does seem to know and support the Direcotor's agenda. However, they are never confirmed to be related, and it's unknown if the Unknown man wears a Hairpiece to disguise little horns on his head.
 * Fridge Brilliance: The Diclonii are chained up and naked in the facility making some really creepy Fan Service. What else is naked and locked up by humans? Animals. The Diclonus are nothing but animals in their eyes.
 * Germans Love David Hasselhoff: The show didn't get very far in Japan (partly due to being hardcore enough that it couldn't be broadcast on-air even in Japan), but was a major Sleeper Hit in America through DVD sales.
 * Same for the actual Germans.
 * Internet Backdraft: This seems to be one of the few series that 4chan seems to legitimately hate.
 * Les Yay: As said before, Nyuu is a girl with the body of a 18 year old and the mind of a 2 year old and as a result has no inhibitions at all. Kouta knows how to keep her in check quite well, but when he's not around she practically sexually assaults a number of the other girls in the house.
 * As potentially Squicky as one of these instances was, when Kouta drags Nyu out of the room and scolds her, Nyu's reaction is one of the story's few truly funny scenes.
 * Later in the manga,
 * Magnificent Bastard: Chief Director Kakuzawa.
 * Moe: Nyu. She loses some of these traits in the manga when she learns to speak and behave properly.
 * Nana too, in her own way.
 * Lucy has her own version of Moe when she's in her Woobie phase.
 * Moral Event Horizon:.
 * Narm: Almost all of the gory scenes wind up being this due to the art and how over-the-top it is.
 * Ship-to-Ship Combat/Armed with Canon: Between the Anime and the Manga, if you can believe it. The manga all but explicitly states Kouta and Yuka are the Official Couple, but the anime seems to ship Kouta with Lucy. The anime also attempts to make Lucy more sympathetic by removing Lucy's tendency to laugh maniacally while killing people and Flanderizes Yuka's Clingy Jealous Girl moments.
 * Tear Jerker: Especially the manga. Nana gets a lot of this.
 * Unfortunate Implications: Apparently, a seventeen-year-old girl who has no sense of modesty and acts like a toddler is supposed to be cute and/or hilarious!
 * The Scrappy: Tomoo is pretty much the most hated character in the series. A Deviantart user even created a contest asking for people to draw him dying in some way.
 * Yuka is a close second. See her entry below.
 * The Woobie:
 * Iron Woobie: Kohta, Nana, Mayu
 * Stoic Woobie: Kurama
 * Jerkass Woobie: Bando, Mariko, and Lucy.
 * Lucy, Destroyer Of Worlds:So very, very much
 * Woobie Species: The Diclonii. Bonus points for the bulk of them going down the Woobie, Destroyer of Worlds road.
 * Subverted with Yuka, who only thinks she's one because she's kept ignorant of the pain of others around her.
 * World Half Empty: After repeatedly showing that Lucy/Nyu had only acted as the humans around them acted, meaning that Diclonii raised by loving parents would be no more likely to become evil than humans, Were you expecting a hopeful solution when Humans Are the Real Monsters and are the ones raising the People of Mass Destruction?

Lucy

 * Alternative Character Interpretation: Quite a lot, considering the ambiguity surrounding whether the Diclonius' are genetically predisposed towards wiping out the human race.
 * The Inner Voice is also subject to this: is it the root of her DNA speaking to her? Is it another personality that formed through all of the abuse breaking her? Is she the Embodiment of the Diiclonii? Or is she some combination of all three?
 * Base Breaker: Naturally.
 * Die for Our Ship: The Lucy hatedom can get pretty rabid, but how much of this is Die for Our Ship and how much is simply hating Lucy because she's a villain is completely impossible to determine.
 * Draco in Leather Pants: Now, this was completely deliberate on the writers' part, since Evil Is Sexy and Lucy is one of the most sympathetic mass murderers in anime history with a genuinely powerful, and surprisingly, well executed Freudian Excuse, but regardless: to hear her fanboys (and more than one fangirl) talk, you'd think that she had never done anything wrong and just needed a hug to be turned into an angel of sweetness and light, never mind the fact that she started off the series freely killing any human except for Kouta who ever crossed her path. Her romantic rival, Unlucky Childhood Friend Yuka, is of course turned into Ron the Death Eater, and her Clingy Jealous Girl tendencies are Flanderized to the point that the Lucy fandom often gleefully wish for Lucy to dismember Yuka. Of course, Lucy is not only a Clingy Jealous Girl, but a Yandere and Cute and Psycho who slaughtered an entire carnival full of innocent people when Kouta snubbed her, as well as wanting to erradicate mankind... but don't tell that to her fans, or they'll tell you that they all deserved it.
 * Not only that, but they'll also say that they're happy Lucy killed them all. Especially
 * Evil Is Sexy: Lucy drops Nyu's particular type of Moe, but turns into a deep-voiced Badass Yandere with major Woobie credentials.
 * Jerkass Woobie: Is nearly a Complete Monster for her actions but is still a major Woobie, Destroyer of Worlds. Be ready to feel the urge to sock her in the face... just before giving her a hug. That's Lucy in a nutshell.
 * Moral Event Horizon: was so horrible and over the top that, even when Lucy became The Atoner, plenty of fans thought that there was no atonement for that. And to be fair, so did Lucy herself.
 * Others also add after the threat she posed was completely neutralized.
 * And for some, it was her
 * Fans may split on whether or not Lucy herself crossed it, but everyone agrees that
 * Ron the Death Eater: She manages to be an odd case that's a victim of this along with Draco in Leather Pants. Now, Lucy is clearly not innocent by any measure. However, there are some that think of her as nothing but pure evil who would always kill others as soon as something goes wrong, just because. Now granted, she certainly shows this behavior early in the series, but as the story goes on, it's made plain that, yes, she does feel awful over what she's done, and does try her best to NOT kill anymore and would've been content to live with Kouta and her friends. However, the people of the Diclonius Research Facility always keep screwing her over and over, and forcing her back into killing people, making it difficult to nearly impossible for her to atone and any hope she can find in humanity and a better future grow dimmer each time. And she's being manipulated by a Split Personality that represents her innate Diclonius instincts, which she first tried to suppress but it soon became her Enemy Within when given life by the pileup of all the emotional trauma she'd endured. Seriously, the girl just can't win.
 * Unintentionally Unsympathetic: She is played up as a Tragic Villain, but some find it hard to feel sorry for her when she murdered Kouta's family out of petty jealousy and was Easily Forgiven for it. It was also shown that before she met Kouta, she killed families just so she could stay at their houses at night. You could count with with your fingers how many people she killed actually deserved it.
 * It could be argued, though, that what would seem like "petty jealousy" to most people felt like something else to Lucy due to Kouta being the first human being to ever show any compassion to her and forge a connection with her. Finding out that Kouta had lied to her about his cousin's gender, thus lied about which girl he'd rather spend time with at the festival, made Lucy think that every feeling for her and act of kindness he displayed might have been all lies as well, and she, being already quite unstable, wasn't able to handle the emotional turmoil in a healthy way. While far from justifying or excusing what she did afterwards, it does make her more pitiable.

Yuka

 * Angst Dissonance: One of the biggest non-shipping reasons for her becoming The Scrappy, being one of the most well-off characters in the series, but complaining about her unfortunate circumstances more than any of them.
 * Die for Our Ship: Lucy/Kouta fans LOVE to bash Yuka for being clingy, despite Lucy also being clingy in other (and scarier) ways. It makes you wonder if those fans really appreciate the Lucy/Kouta pairing for how screwed-up it actually is in canon...
 * People in the West bash her since they're both cousins, and incest of any kind is largely taboo and considered "disgusting".
 * Ron the Death Eater: Lucy/Kouta fans seriously flanderize her Clingy Jealous Girl tendencies to Scrappy levels to make room for Lucy to kill her and win Kouta's affections.
 * The Scrappy: Partly due to Angst Dissonance, partly due to shipping issues, and partly due to her annoying voice in the English dub.
 * Yuka being angry at Kouta for not remembering their childhood even though it's due to the trauma of seeing his father and sister being slaughtered in front of him (and it's implied that she knows Kanae didn't die from an illness, so it's likely that she knew about their fate) probably has something to do with the fanbase's dislike of her.
 * Unintentionally Unsympathetic: See above for the reasons.
 * Wangst: SeeAngst Dissonance. While several the rest of the cast is all dealing with serious pain, Yuka is the one vocally crying and complaining about her issues, which are all very small potatoes by comparison. Granted, she has no idea that others suffer so much, but her angst still comes off as very childish. Lucy would probably roll her eyes or laugh her ass off if she heard any of it.

Nana

 * The Woobie: In a series full of woobies, Nana takes the cake. Everyone loves Nana. She get's pushed around so much. Poor Nana, indeed.
 * Iron Woobie: And yet through all this pain and anguish, she keeps pushing on.

Mayu

 * Hollywood Homely: When she's first introduced she is described as looking like the homeless child she has been for perhaps several weeks at that point. Problem is, virtually nothing about her physical appearance suggests this.

Bando

 * Complete Monster: Surprisingly averted due to Character Development from a psychopathic soldier who joined his Spec Ops unit only to be able to legally kill people who'd give him a challenge to a Jerkass who considers everyone as shit but has a moral code to not be indebted to anyone, and is also obsessed with having his Revenge against Lucy, to the Jerkass Woobie and Jerk with a Heart of Gold that he is in the end who actually saves Mayu from the Unknown Man in a truly Badass manner, but is still obsessed with killing Lucy.
 * Jerkass Woobie: He's an asshole, yeah. But he still manages to come up as more decent than others assholes here.
 * Rescued from the Scrappy Heap: While a few people find his anime counterpart amusing in some cases, most would agree that he has little to no redeeming factors and would rather have seen him killed by Lucy than spared. His manga counterpart has much of his jerkassery toned down considerably, given multiple moments of character development and badassery and is widely considered to be one of the best characters in the manga.

Director Kakuzawa

 * Complete Monster: Played with. At some point in the past, he'd at least been a decent father to his daughter Anna, {{spoiler|even allowing her human self an exit from the monstrous experimental form he turned her into]]. In the present day narrative, however, he shows no love for any of his children, has no qualms with cold-blooded murder, torturuous experimentation, and even rape, and is planning to bring about the extinction of all humans and Dicloni on the planet so that he can usher in a new age of only Dicloni, with him as the new world's God. And there are no redeeming qualities to mitigate this horrific level of pure evil villainy.
 * Love to Hate: Manga only. Director Kakuzawa is a fairly despicable character but undeniably a darn good villain.
 * Magnificent Bastard: Again manga only. He practically has everything fall into his hands, has people dance in the palm of his hands and almost always has a stoic face and lets little bother him. He's practically a textbook example of what a good corporate villain might be like and one can't deny that he's got some style. Whether it’s using his own employees like pawns, firing off vector virus missiles or having a second diclonius son at the ready, he seems prepared for anything.

Nousou

 * Alas, Poor Villain:
 * Alternative Character Interpretation: Did he
 * Complete Monster: If you do NOT see his regret as sincere, then he's this.
 * Complete Monster: If you do NOT see his regret as sincere, then he's this.
