Good Angel, Bad Angel: Near the end of the manga, it's revealed that "Lucy" (real name "Kaede") isn't the Hyde to Nyu's Jekyll. In fact both of them are alternative personalities of the original Kaede, who was a relatively normal girl until she snapped under the constant abuse and death of her dog, where her evil instinct took over and created Lucy, who only cared about exterminating humanity.
Good Eyes, Evil Eyes: Just contrast the innocent Nyu persona's wide, bubbly eyes with the narrow, hateful, tortured eyes of the Lucy persona.
I Cannot Self-Terminate: Toward the end of the manga, the Lucy/Kaede and Nyu personalities beg Kouta to kill her now that her homicidal Diclonius instincts personality has finally taken over, and she must depart their ruined body, leaving the DNA voice in control, not to mention agony.
Important Haircut: Lucy/Nyu chops off her hair in order to impersonate Kouta's younger sister Kanae, which signifies Lucy's guilt over murdering her. Coincidentally, it also makes her resemble her younger self.
Monster Roommate: A mass murdering superhuman with horns and invisible telekinetic Combat Tentacles ends up crashing at a random family inn owned by Kouta and Yuka, although they aren't made aware of it at first.
Ms. Fanservice: Just about every other scene has her showing off her fairly toned figure. Ahem, not that we mind.
Naked First Impression: Kouta and Yuka find Nyu naked on a beach. This is averted for Kouta, however, as he first met Lucy when they were younger.
Split Personality: One has the mental capacities of a small child, the other's an insanely powerful killer out to take out a significant portion of humanity. The switch between Lucy and Nyu and back is triggered by either a nasty injury (usually a blow to the head) or a very traumatic memory. She even holds the current page image. In fact, it turns out that Lucy and Nyu are both split personalities.
Split Personality Takeover: The shift between Lucy and Nyu; Lucy knows when Nyu has been in control, but doesn't try to stop it from happening.
Star-Crossed Lovers: She and Kouta have... so many fucking issues between them that it's a miracle they still love each other at all.
Tragic Dream: Her love for Kouta extended to wanting to marry him, which Kouta only finds out towards the end of the final chapter years after her death in the letter she left for him.
The main character of the series, she is a teenage Diclonius around 15 years old in the beginning and 17 in the end. Lucy has 4 vectors in the anime and around 12-15 in the manga with a limited range of two meters. However, she demonstrates prodigious control over her vectors and can be swift and lethal within that range in addition to being able to use nearby objects as high velocity projectiles to kill at greater distances. She is also capable of stopping or deflecting most standard ammunition. Her great skill, murderous intent and ability to reproduce have caused her to be regarded as the most dangerous of the Diclonius.Lucy hates humans mainly because of how she was treated by her human peers as a child. Consequently, she discounts non-Diclonii, claiming they are not real people, to the point of stating that she has "not killed anyone yet". She seems to lack empathy, kills without much concern, and acts sadistically. Despite this lack of concern for human life she will not harm Kouta, as he was her only childhood friend.
Tropes associated with Lucy:
Adaptational Badass: Played with. While certainly powerful and competent, Lucy in the manga is as likely to kick ass as she is to get her own ass kicked and usually relies on clever tricks or diversions to get the upper hand. Her anime counterpart however seems to bulldoze through everyone casually without the slightest bit of effort, only meeting her match with Mariko. The difference is that most of her anime counterpart foes end up being a lot weaker or less competent than their manga counterparts and the fact that even before her vectors get longer, Manga Lucy has shown more vectors and a much more vicious and merciless nature.
Alas, Poor Villain: Yes, she's a bitter, mass murdering bulldozer, but holy fuck, she did not deserve a life like that.
All of the Other Reindeer: Lucy was relentlessly bullied by the other children at the orphanage due to her emotionless demeanor and her horns. She later snaps and slaughters them all after they take the puppy she'd been caring for and beat it to death right in front of her. Later, thinking she has been betrayed by Kouta, she goes on a massive slaughter rampage.
Aloof Big Sister: She kills her half-brother along with his father, Director Kakuzawa. It's a Mercy Kill, since her brother is born specially for impregnating her and he's controlled by Director Kakuzawa. Lucy expresses remorse over killing him.
Later on, she decides to kill Mayu, when she learns enough of her secrets to jeopardize Lucy's life with Kouta. Her face is tinged with tender regret, as are her words and gestures, but it is clear she still means to do it, and only Bando's sacrifice stops this in time. Mind you, Mayu is not a physical or romantic threat, and has cared for her for many months by this point. The worst part is, it would have only postponed The Reveal for those at Maple House by a few days. That said, she chose not to follow up on it after she failed to kill Mayu the first time, and when Kouta finds out anyway, Lucy entrusts Nana to protect Mayu, showing that she still lives up to the "Big Sister" half.
Played with early on when Lucy comes across Mayu's little dog, Wanta. She looks down at the dog, which is barking frantically at her but unable to run away because it's tied to a leash, and we're treated to what seems like a Gory Discretion Shot as we hear Lucy use her powers. When Mayu comes outside, the audience's expectations are subverted when it's revealed that Lucy actually cut the dog's leash. This was our first hint that Lucy's not all bad.
Apocalypse Maiden: Toward the end of the manga, her homicidal Diclonius instincts personality finally takes over and starts killing humans everywhere on the world at rates that would make the deadliest WMDs look like mere fireworks in an attempt to destroy humanity in a spiteful decision that since Diclonii, and mainly her, can't rule the world, she'll destroy it.
The Atoner: As things go along, you'll find that Lucy really does regret her actions, and she tries her damnedest to make amends for it several points in her history, because ultimately, she's content to live with Kouta and would rather stop killing (hence why she doesn't do so in front of him). Unfortunately, this being Elfen Lied, fate just keeps trying to pull the rug under her feet anyway. At the very end, when she has her Superpower Meltdown, she atones in the only way she can - by convincing a very reluctant Kouta to Mercy Kill her.
Ax-Crazy: In the manga, at least, Lucy doesn't just nonchalantly tear people to pieces, she does it with a huge grin on her face and a really Evil Laugh.
Bad Ass: Most definitely. At her weakest, she's considered a terrifying killer capable of killing dozens of armed guards with nothing on. By the end of the manga she's capable of destroying islands, cities and nearly taking out the entire planet.
Blank White Eyes: In the anime, when Lucy her right horn gets knocked off by Number 35 (Mariko). She appears to be in shock/comatose (complete with white eyes) for several minutes.
Because You Were Nice to Me: Kouta was the first person to treat her kindly and befriend her despite knowing she's different. Her days with him are her only happy memories, which is why Lucy fell deeply in love with him and he's the only human she refuses to harm.
Beleaguered Childhood Friend: She and Kouta were very close friends when they were kids. In the present, he has conflicting feelings about her since she's now a mass murdering sociopath in the run, not to mention she's responsible of his own family's death. In the end, he has to reconcile his lack of ability to forgive her with his lack of ability to hate her (no matter how much he says otherwise).
Berserk Button: Threaten Kouta at your peril. Harm a dog at your peril.
Broken Bird: Treated like crap by most humans, bullied relentlessly during her childhood... yeah, Lucy's about as broken as it's possible to get.
Bully Hunter: Though not actively hunting, Lucy takes this trope to the logical extreme and beyond in her backstory. Just...don't hurt dogs near her, ok? Less a case of wanting to get her own back on bullies, more a case of having a full-on psychotic break.
Byronic Hero: Morally neutral? To put it mildly. Largely concerned with personal interests? Check. Disrespect of common authority? Check. Tragic past? Dear God... Defined by conflict, inner and outer? Definitely. Attractive? Oh yes. Introspective loner? Check. Cynical, jaded, brooding and self-destructive? Definitely.
Clingy Jealous Girl: In the most frightening way imaginable. Her jealousy involves murdering Kouta's family because he went to the festival with Yuka instead of her. She spared Yuka's life only because Kouta would hate her if she killed her.
Late in the manga, as she leaves her Maple House family for the last time, she asks Yuka to care for Kouta and Nana to protect their family. When Chief Kakuzawa makes his offer, all the residents of Maple House are in her thoughts, as she only wants to get back to them. Probably not at the same level as Kouta, but she has begun to put aside thoughts of the others as obstacles.
Combat Pragmatist: Her vectors can't reach beyond two meters... so she'll just throw a car at you, as Bando learned the hard way.
The Comically Serious: Yeah, some of her funniest moments involve her saying something either really snarky or really odd while in a complete deadpan. Some of it is played for Black Comedy.
Contralto of Danger: In her Nyu persona, she is like an innocent young girl. When she switches to her Lucy persona, she has a much lower voice to match her dangerous and threatening nature.
Creepy Child: In flashbacks, which probably contributed to peoples' mistreatment of her.
Kind of a Catch-22. She became an Emotionless Girl in order to deny her tormentors the joy of seeing her in pain, which then became another reason why she was despised, reinforcing the original bigotry and egging some on to make her react. They got their wish, yeah.
Curb-Stomp Battle: Pretty much any "fight" she takes part in, although this is reversed in the battle between Lucy and Mariko, but only in the Anime. And also completely Inverted in her second fight with Bando in the Manga. Averted by her duel with Nana, which is more or less an even match; Nana gets the advantage, but Lucy wins because she's far more willing to hurt Nana than vice versa.
Determinator: No matter how many people oppose her. She will find Kouta and she will apologize to him, and anyone who gets in her way will die. Horribly. Also, if your name is Kurama, don't ever let your loved ones near her. She will kill every last one of them. And there's nothing you can do to stop her.
The Dog Bites Back: After the bullies at the orphanage push her too far by killing her puppy right in front of her, Lucy wastes no time dishing out swift payback with her newly activated vectors.
The Dreaded: Being a mass murdering girl who can rip apart armed soldiers and wants 99% of the people see sees dead will do that. Practically the only people who don't end up wetting themselves when she's near is Kakuzawa Senior who gets his head ripped off and Bando who gets mutilated. Though Bando at least is capable of putting up a good fight the second time.
Enemy Within: She has a pretty complicated mindset. Ultimately, however, it is her DNA personality, the embodiment of her basic instincts, that is the undisputed, unambiguous villain who pushes her to do everything horrific on screen.
Evil Is Hammy: Loves setting up cruel Mood Whiplashes in particularly creepy ways, to the point where she may even be Trolling the readers. Loves laughing on the dead bodies of her victims. Always boasts and taunts about her power whenever she meets a foe she hates. And yet can somehow find a reservoir of Moe whenever she's near Kouta and boast about why she loves him.
Evil Laugh: Manga-only. On some pages, it is rendered with an extremely thick font.
Evil Redhead: Though she is more specifically a hot-pink head, and it's more specifically her DNA Voice that's truly evil.
Evil Sounds Deep: Lucy's voice is low, deep, and quite ominous in comparison to Nyu's chirpy, childish, high-pitched voice.
Many of Lucy's traits are identical to Johan Liebert. Both of them were once innocent kids, but turned insane when affected by secret military experiments(in Lucy's case, her insanity was the result of the DNA voice stemming from her Diclonius instincts as well as just having a rotten life due to bigotry. While Liebert's twisting was the result of sadistic experiments, the Diclonius are the result of a random evolution supported by the delusional Big Bad), are experts at manipulating people, are comparable to The Antichrist, have ambitions to end the world, passion of destroying human life, multiple personalities, traumatized their lovers, an obsessive and murderous love towards someone that cares for them, Biblical and German-related motifs, and try to have the person who actually cared for them kill them. The difference here is that Lucy is portrayed much more sympathetically.
Also, her traits matched with Dragon Ball's Lunch. Both have multiple personalities; one is a ditzy nice girl, and the other is a sociopathic heroine, but also stoic. Eventually, the latter sides eventually gain a heart of gold and working with the main character and his friends. That gives them both an odd friendship with a girl who is a non-combatant (Yuka and Bulma) and an unrequited love interest (Kouta and Tenshinhan). They eventually disappear after the end of their works (while the former being killed by Kouta in the manga and having her bad side killed by the army in the anime with the latter being written out).
Forgotten First Meeting: Kouta initially met Lucy in his childhood after she killed her first victims. Unlike everyone else, he found her horns fascinating and forged a strong bond of friendship with her, thus keeping her murderous Diclonius instincts repressed. However, he erased her from his memory after she brutally killed his father and sister right in front of him because he neglected to specify his cousin's gender.
Freakiness Shame: She hated her horns since she was bullied because of them, but Kouta told her he thought they are cool.
Friendless Background: She spent her childhood in an Orphanage of Fear where she had no friends and was frequently bullied by the other children for her horns and emotionlessness. The one person who it seemed like she was gonna become friends with at the orphanage later betrayed her and sold her out to the boys that had been bullying her. She then made two more attempts to reach out to someone else and become their friend. The first ends with her feeling betrayed once again, while the second ends in her new friend being killed and her being captured. After that it's sort of understandable why she stopped trying.
Full-Frontal Assault: The fact that Lucy has nothing on but a helmet in the first scene of the anime does not stop her from taking on and killing dozens of soldiers as she fights her way free from a military facility.
Good Girl Gone Bad: She was nice and sweet, until a group of orphans beat to death Lucy's puppy, the only being in the world she actually cared about. And they found out about it from a girl who pretended to be her friend, the first human she was beginning to trust. That's when her murder spree began, although it was put down eventually thanks to Kouta. However, after he lies about his cousin's gender and she finds out the truth, she's gone for good.
Ground Punch: The manga has Lucy using her vectors (basically invisible hands) to strike the ground in order to jump long distances, they even leave hand marks and small craters behind.
Hearing Voices: This is how the (presumably) genetic urge to Kill All Humans manifests itself to Lucy for the first time. It probably put a damper on her childhood relationship with Kouta when she didn't even notice that she was strangling him.
The Heartless: Her "DNA" voice could count since it's the result of all the abuse she went when she was a child.
Humans Are the Real Monsters: Lucy believes strongly this (and textually says this). And considering all she'd been through, one can't honestly blame her.
Implacable Woman: Go ahead. Keep throwing shit at her. She will always plow through it to get to you.
The Juggernaut: A very graphic version of this trope. It's shocking to those who hear "Juggernaut" and think of the huge, muscly guy from X-Men. Lucy is a cute pink-haired teenage girl... until she rips you in half, spilling your blood everywhere.
Averted in the manga; Kouta does not forgive her for brutally murdering his dad and sister in cold blood, and she dies by Superpower Meltdown, but the personalities of Kaede and Nyu are reincarnated as twin girls and are reunited with Kouta some years later. In the anime, however, she is implied to survive her last showdown with the army, and while Kouta doesn't exactly forgive her (or at least not her actions), he's much more sympathetic to her plight, and he'd rather see the killing stop than seek revenge.
Her Anime fate can very well be a subversion of this, as it's strongly implied (even more so if we add an element from the Manga) that Kaede purposefully killed her Lucy side so Nyu can finally live in peace with Kouta.
Brutally murdering Kouta's father and little sister without any provocation was so horrible and over the top that that even Lucy herself agreed that there was no atonement for that.
When she goes on her rampage in the festival, she kills a woman because she showed concern for Lucy. In this case, however, it's slightly justified in that Lucy was... not exactlyin her right mind at the time.
Slicing off Nana's limbs after the threat she posed was completely neutralized.
Trying to kill Mayu after Mayu tried to help her. However, this is partially negated by Lucy's own regret at even considering it (see Shoot the Dog and Pet the Dog below).
Killing an entire family in a house, both so she could crash for the night and because she was jealous at how the family was having a happy life. This event was meant to really show just how bitter the world made her.
She keeps attacking Alicia and Barbara who are trying to save Nousou while they are helpless and she kills one of them. It's not like they didn't see it coming, since they took her home.
Kick the Morality Pet: She brutally killed Kouta's father and sister Kanae because he lied to her about his cousin's gender. Quite a bit of guilt over said incident remains in her heart.
Kick the Son of a Bitch: The cruel kids at the orphanage, along with Bando (the first time around), the Unknown Man, and Kakuzawa (Junior and Senior), all had it coming.
Kids Are Cruel: As a child, she was tormented by cruel kids because of her "cute little horns" and her emotionlessness. They even killed a puppy just to mess with her. Gets worse when you realize they wanted to torture the dog first to mess with her. It just happened to die on the first blow.
Last Kiss: In the anime, Lucy kisses Kouta shortly before confronting the soldiers who have been assigned to kill her. Her fate, however, is left ambiguous.
Limp and Livid: Quite a lot. Whenever Nyu flips over to Lucy her head drops so her hair covers/shades her eyes.
Long Lost Sibling: In the manga, she has a younger half-brother, the first male Diclonius. Upon meeting each other, she kills him. She doesn't hate him, but she did it because their kind can't exist anymore and the fact he was being controlled by Kakuzawa, making it a Mercy Kill.
Love Martyr: For starters, it was her love of Aiko that made Lucy subject herself to years of human experimentation - tantamount to a living hell, yet she was fine with it as long as Aiko survived... and when she was told Aiko didn't survive, Lucy was crushed. When she gets free, she spends the rest of her life trying to find Kouta so she could apologize for what she did to his family, even though she knows she can't atone for it. When that happens, and he flat out says that he hates her for what she did to his family, she still embraces him when he accepts her into his house in exchange for not killing anymore. When he takes the bullet for her from Kurama, it was her love of Kouta that drove her to heal him at the cost of a Superpower Meltdown.
Made of Iron: She survives taking an anti-tank slug to the head in the first episode. To be fair, though, the thing barely grazes her, she's wearing a helmet, and she has her vectors to protect her. She still does survive falling hundreds of feet off a cliff into the ocean without drowning immediately afterwards though.
Can be seen alternatively as a female version of Lucifer (the devil, which fits her role as an evil mass-murderer), and also sounds like "lucid," which could refer to Nyu only initially talking in full sentences when Lucy is at the wheel.
Lucy is also the name of a protohomonid skeleton with an upright gait and small brain capacity, suggesting a missing link between the great apes and modern humans. Lucy, being the first of her kind capable of "proper" reproduction, could also potentially serve as a missing link between humans and some future Diclonius race.
Murder Is the Best Solution: If you even slightly irritate or wrong her in any way, shape, or form, you're dead. Justified to a degree, as her... not-so-happy life prompted this as a defense mechanism for her.
Murder the Hypotenuse: This is what she is trying to do to Yuka. The only way that stops her from attempting to do that is Kouta's presence near her. In the flashbacks, she does this to Kouta's sister and father.
Not So Stoic: In the manga, whenever she's on a killing spree, she's happier than a kid high on weed.
Off with His Head!: Her preferred method of killing people she hates. It's swift, fast, bloodless, and efficient. Everyone else (including Bando) fall under Ludicrous Gibs.
Omnicidal Maniac: Pretty damn much. Justified, in that Kaede, the original personality, had been put through so much abuse that she created Lucy specifically to act on her (supposedly) inborn drive to butcher all humans.
Only Known by Their Nickname: Most people seem to either not know or forget that "Lucy" isn't her real name. As revealed toward the end of the manga, "Lucy"'s real name is Kaede.
Pet the Dog: Her moments of compassion are rare, but very poignant, because it shows that she still has some humanity left in her fractured mind. As time goes on, both in the anime and the manga, the more these moments pile on, the more humanity ultimately returns to her.
The first instance that shows she still has a heart came in the form of her meeting Mayu's dog in a cage. While it looks like she killed the puppy, it turns out that she actually cut the rope that kept him restrained and allowed him to reunite with Mayu.
Speaking of Mayu, Lucy actually took the time to protect her from a fight with another Diclonius, and that was when they first met. She literally had no reason to even acknowledge Mayu's existence, but she went out of her way to protect her anyway.
She may be a mass murdering sociopath fueled by her hatred of humans, but her ability to love is powerful. The shit that she allows herself to suffer through, purely for the sake of her loved ones, is her single greatest trait. See Undying Loyalty below.
Nothing will excuse her Kick the Dog moments, but she has shown that she can (and does) learn from her mistakes if given a chance. In particular, after the incident with Kouta's family, she refuses to kill Aiko's asshole dad purely because she'd rather not make Aiko sad; she encourages and actively tries to get Aiko to reunite with her mother; she offers to take the blame after Aiko accidentally killed her father; she doesn't commit infanticide after what happened with Kanae (and even feels bad about trying it with Mayu so Kouta wouldn't have to relive his memories of Kanae); and she refrains from killing anyone in Kouta's presence, no matter how much she personally hates her targets.
She was surprisingly regretful at the idea of killing Mayu (an attempt to keep Mayu from triggering Kouta's own memories as a result). To her credit, she doesn't do it again, and even entrusts Nana to protect her towards the end of the manga.
She hated her mother for all her life... but when she finds out the truth of what her mother went through, Lucy forgives her.
Her genuine grief over her murders of Kouta's father and sister. That was awful, but it was nice to see Lucy herself show remorse for once. She knows she can't fully atone for it, but she still wants to atone anyway, which says a lot about how much it was eating her up inside.
When she accepts his offer to stay with him on the condition that she doesn't kill again, it shows that, yes, she really would rather just stop killing altogether if it meant living a normal life.
When the Maple House is attacked, and Nyu holds off much of the invasion force, Lucy wakes up, and notices that Kouta had regained his memories of her killing his family. Perhaps resigned to the fact that she and Kouta could never be together, the first thing Lucy does... is to ask Nana to care for the Maple House and its residents. Furthermore, she even asks Yuka, of all people, to take care of Kouta - something that was utterly unthinkable at the beginning of the series.
Redemption Equals Death: In the manga, she defies her DNA Voice's desire to go on a Suicidal Cosmic Temper Tantrum by stopping her vectors from causing anymore damage and asking Kouta to Mercy Kill her. The anime is more ambiguous, but she does lose her other horn and a woman in her figure shows up in front of the Maple House.
Reincarnation: At the end of the manga, where the twins are apparently separate reincarnations of Kaede and Nyu.
Retired Monster: Yes and no. By the time the series starts, Lucy pretty much has murder as the only option regarding humans, but she seems to limit her present-day killings to people who actually deserve it. She does get better, though, ala Defrosting Ice Queen.
Sanity Slippage: A chapter dedicated to her childhood shows she got so unstable and murderous through this trope.
Sean Connery Is About to Shoot You: When Bando decides to kill Lucy by shooting the grenade next to his dead teammate, he forgot an important object: the teammate's automatic machine rifle. It went to hell from there.
Senseless Sacrifice: Before her capture (sometime after she killed Kouta's father and sister), she turns herself in as a final attempt to give humanity a chance and to save a new friend's life. She later finds out when being bound in the very place first seen that her friend died from her wounds and that practically drove Lucy to cross the Despair Event Horizon.
Shameless Fanservice Girl: Unlike Nyu, she does know that being naked is a problem, but she often has other things on her mind.
Shoot the Dog: The only reason she even considered killing Mayu was because Mayu remembered Lucy's fight with Nana. Lucy feared that Kouta would regain his own memories if Mayu put two and two together, so she tried to kill her to keep that from happening, but Bando took the bullet for Mayu. This oddly merges with Combat Pragmatist (even if unintentionally) and Kick the Dog (since it was still a pretty selfish thing to do).
Single Woman Seeks Good Man: She falls for Kouta because he is the first person to be genuinely kind to her and not shun her because she is different (he even finds her horns cool). Even though she gets, to say the least, deranged and murderous later in life, she continues loving Kouta for his virtues and refuses to harm him.
Sociopathic Hero: She does show lack of regard for human life and has shown empathy for other people (namely Aiko) in the past, but by the time Elfen Lied starts, she's too far gone in her hatred of humans.
The Southpaw: She's not left-handed, but both times she uses a machine gun, she fires it with her left hand.
Start of Darkness: Episodes 8 & 9 show Lucy's backstory, along with the only happy day she spent while with Kouta when they were kids. The manga does this sooner, at the time of episode 6.
Sugar and Ice Personality: Cold and deeply cynical, but only because she's been hurt so badly every time she lets her guard down. She can be very genuinely caring and insanely loyal towards those she becomes attached to. She may slaughter humans without hesitation or remorse, but her capacity for love is still very real.
Superpowered Evil Side: She's it, except there's an even more evil side that's essentially her basic instincts.
Superpower Meltdown: Toward the end of the manga, Lucy goes into a literal meltdown due abusing of her telekinetic powers while destroying some planes and then for saving Kouta.
Theme Music Power-Up: In the manga, Lucy sings the German song "Elfenlied" while taking on an entire army from thousands of kilometers away. Apparently, the more thematic the song, the bigger the powerup.
Then Let Me Be Evil: She's a member of a race genetically predisposed towards the destruction of the human race. Which was only ever triggered because the humans she met all treated her like shit. Nice going there.
Token Evil Teammate: In the main cast (consisting of herself, Kouta, Nana, Yuka, and Mayu), she's easily the most unhinged and villainous of the bunch.
Tragic Villain: So very, very tragic. A broken little girl who became a murderous monster after she snapped at the world's relentless cruelty and her own budding insanity.
Tranquil Fury: In the anime, where she kills without a change in her facial expressions.
Tsundere: Type A, when she was young. Also when she's older, she tries to show Kouta the cold shoulder, but has some adorable moments when he faces her.
Tsurime Eyes: Narrow, tortured and focused, in contrast to Nyu's bright and happy ones.
The Unfettered: She will find Kouta, and she will express how awful she feels about killing his family. No way you'll ever stop her from doing that. No way she'll let you stop her from that single goal.
Alternatively, her DNA Voice personality has no reservations about doing anything in her considerable amount of power to kill all the humans and replace them with her species.
Undying Loyalty: If her Fatal Flaw is that she Desperately Craves Affection, then her greatest quality is her insane devotion to the people she loves. In fact, her loyalty is arguably greater than her desire for affection, because she willingly puts herself in harm's way for the people she cares about, frequently sacrifices her own betterment in exchange for theirs and absolutely refuses to abandon them or hate them even if they treat her badly.
Ungrateful Bitch: She once tried to kill Mayu right after Mayu saved her from being killed. Granted, Lucy chose not to continue attacking Mayu after she dealt with Bando (who tried to save Mayu as a result), so one could argue this was at least partially attributed to her being a Combat Pragmatist.
Villain Protagonist: She has killed armed men and innocent children, for reasons ranging from "trying to kill me" to "You killed my dog" to "I envy your happy, normal life, and I need a place to crash." Here's our heroine, ladies and gentlemen.
Vomit Discretion Shot: During her breakdown at the summer festival we hear her vomit with the back to the audience (Strangely, tons of severed heads and oceans of spilt blood are not as bad as a small pool of vomit).
She's actually not that powerful compared to some of the other diclonii; Nana has longer vectors and can hold her at bay, while Mariko is an outright nuke. Lucy is a far more experienced killer, and when Nana tries to go easy on her, Lucy rips her limbs off.
Subverted in the end of the manga where her vectors can split islands and have a reach of at least hundreds of kilometers.
Woman Scorned: Sure, Kouta! Don't tell Lucy that you're going to the festival with your female cousin! Even if she finds out, it's not like she'll go so far as to murder your little sister, your father, and dozens of other people, right?
To be fair, Lucy admits that if Kouta had told her he was going to the festival with a female cousin, she probably would have hunted down the cousin and killed her.
Woobie, Destroyer of Worlds: 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's 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 herand 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".
Yandere: Played Up to Eleven. As it turns out, the reason she killed Kouta's father and sister was that she was angry at Kouta for lying to her and saying that the cousin he was going round the festival with was a boy instead of a girl (apparently, even if Kouta did tell her it was a girl, someone was going to die anyway). Disproportionate Retribution at the worst, although she seriously regretted it later, to the point that the thought of eventually apologizing to him gave her the will to survive.
Not a separate character in the strictly technical sense, Nyu is the split personality of Lucy that developed after a .50 BMG round grazed the metallic helmet protecting her head. Nyu has a childlike personality, an infantile knowledge of the world, and lacks spoken language skills, only able to say "Nyu" and "Kouta" most of the time. Nyu is innocent and incapable of violent acts, a foil to the normally cold and sadistic Lucy; she is the manifestation of Lucy's "good side".When Nyu is attacked violently she regresses into Lucy; likewise, when Lucy is treated with love and kindness or wants to hide herself from Kouta, she will switch back into Nyu. While Nyu exists first due to trauma, it is believed that Lucy subconsciously encourages her presence due to her feelings of guilt towards Kouta. In the manga, this is confirmed by Lucy herself.
Ambiguously Bi: She only loves Kouta... but that doesn't keep her from groping other girls. Even after she becomes intelligent, she wonders why she wants to Skinship Grope Yuka, likely due to her former self's influence.
Beware the Nice Ones: Let's just say that putting her in danger, hitting her on the head hard enough, or getting her drunk or drugged will make her revert to her Lucy persona.
Blank Slate: She has no useful speech abilities, latches emotionally on to the first people she meets, and frequently doesn't seem to understand what's going on. The anime cuts off before Lucy is reduced to an extended coma and Nyu is allowed to develop. She is even able to talk in full sentences, and is, at that point, a full personality that directly contrasts Lucy perfectly. She still keeps her Verbal Tic, though.
Buxom Is Better: Nyu likes groping bigger breasts and is disappointed of Mayu's small ones.
Cute Mute: In the sense that her trauma left her with a very limited vocabulary. She gets better.
Driven to Suicide: In the manga, when she finds out that she's a mass murderer, she tries to kill herself, but cannot do it.
Helpless Good Side: In spades. Lucy is a psychotic murderer. Nyu is an innocent amnesiac girl who initially doesn't even know how to use a restroom. She's not so helpless when she's able to use her vectors herself.
Heroic BSOD: When she is captured again, she thinks it was impossible that her actual side is the killer.
Innocent Fanservice Girl: Too many incidents to count. Probably the most notable is that she has walked up to Kouta and shoved his hand against her breast, twice, and the 2nd time they were both naked.
Innocently Insensitive: She cheerfully breaks the seashell Kanae gave to Kouta, which greatly infuriates him. Yuka tries to defend Nyu, saying that maybe she broke the seashell because she thought it made Kouta sad.
Lovable Sex Maniac: At least, in the manga. She is constantly making Kouta grope her and molesting the other girls that live at the inn. Subverted in that she doesn't understand the gravity of her actions, and is only (for the most part) copying things that she's seen others doing.
Nice Girl: One of the biggest contrasts to her alter ego.
The Prankster: In the manga, she tries to play a prank on Kouta as revenge for scolding at her (and maybe for stopping her Attempted Rape on Nozomi) by surprising him. The timing of her prank is really bad, as the person she surprise turns out not to be Kouta, but Nana, who attacks her because of Lucy dismembering her.
An 18-year-old student who arrives in the Kanagawa Prefecture to attend college. He is the male lead and Deuteragonist of the series. Kouta lives in a closed-down inn with his cousin, Yuka, while attending university.Kouta has repressed traumatic memories of witnessing, firsthand, the deaths of his father and sister. He ended up in a psychiatric ward for over a year following the event, but eventually made a full recovery. As a result, he is particularly sympathetic towards girls in trouble and is extremely generous to and protective of the girls around him. He is very kind and gentle as well, offering to shelter the various suffering characters he and Yuka stumble across, and treating them as part of his family. He and Yuka both initially meet Lucy as she washes up on the shore of a nearby beach.
Accidental Pervert: Yuka slaps him a lot for this. The first time it happened, Nyu had been out in the rain and her clothes were soaked. Kouta tried helping her change with his eyes closed, but his cousin walked in at just the right moment for his honest explanation to be hardest to believe.
Adoptive Peer Parent: He and Yuka both adopt Mayu despite the fact that they're both university students and Mayu is 14.
Angst Coma: In the backstory, spent an entire year in a coma after watching his little sister Kanae and his father get slaughtered right in front of him by Lucy.
Babies Ever After: The Distant Finale shows him going to the place where he first met Lucy/Kaede to wait for her with his daughter Nyu, who resembles Yuka.
Break the Cutie: Him seeing his father and sister killed got him hit mentally & emotionally hard.
Caught in the Rain: When Kouta and Yuka are looking for Nyu and it suddenly starts raining. By the time they find shelter at a nearby shrine, they're both drenched, so they huddle together for warmth. Yuka admits her feelings for him, kisses him unexpectedly, and tells him that she doesn't want to be separated from him again. Kouta wipes her tears away and returns the kiss. The rain stops just as suddenly as it started, and when Kouta comments on it, Yuka realizes what she did, panics a little, and falls off of Kouta's lap. Cue Panty Shot, Accidental Pervert, and Megaton Punch.
The manga takes their encounter a few steps further...
Chick Magnet: Attracts a teenaged, mutant girl with horns on her head and even his own cousin! Also Nozomi, but she does not fall for him that hard like the others.
Death Glare: To Lucy, right after he regains his memories in the manga.
Deuteragonist: He's the second most important character over here, due to his relationship with Lucy.
Did Not Die That Way: Kouta eventually finds out that his father and sister did not die from an accident and an illness, respectively, but that they were both murdered in front of him by Lucy, and the trauma of witnessing this caused him to block the memories out.
The Dulcinea Effect: Only slightly, but Kouta is undeniably more inclined to go the extra distance to help out a girl in need.
Expy: Kouta bears some resemblance to other characters from Lynn Okamoto's previous works. To Aoki from Lime Yellow and the nameless protagonist of Memoria, who also has a Forgotten First Meeting with a girl he meets many years later. A later one-shot, Allumage, has young boy who looks very similar to Kouta, especially when this child grows up.
Forgotten First Meeting: In actuality, Kouta met Lucy in his childhood after she killed her first victims. Unlike everyone else, he found her horns fascinating and forged a strong bond of friendship with her. However, he erased her from his memory after she brutally killed his father and sister right in front of him because he lied to her about his cousin's gender.
Freaky Is Cool: He was the first person to think that Lucy's horns are cool.
I Will Wait for You: In the manga, after he kills Lucy/Nyu he goes to the place where he first met Lucy/Kaede the last day of the summer festival to wait for her every year, even though he knows she won't come. However, it's implied he manages to meet Lucy/Kaede's and Nyu's reincarnations.
Kissing Cousins: He is attracted to his cousin Yuka, as the temple scene indicates, but then there's Lucy/Nyu muddying things up. In the final chapter of the manga, it's implied they end up together. If Kouta's daughter's resemblance to Yuka is any indication.
The manga also implies that his feelings for Yuka were always stronger than for Lucy/Nyu, judging from his many scenes with Yuka.
Living Emotional Crutch: He is both this and a Morality Chain to Lucy. She still loves him and one of, if not the only thing that gives her the will to go on is the thought of one day finding Kouta again and apologizing to him for killing his father and sister.
Parental Hypocrisy: He tells his daughter Nyu to not play in the mountains, despite the fact he used to play in the same mountains with Lucy/Kaede when they were little.
Parting Words Regret: His last words to his little sister Kanae were a threat that he'd "hate her forever" unless she apologized to his friend Lucy, who Kanae had just accused of murdering people at the festival they were at. He then sees her bifurcated in front of him... by Lucy herself. He shows clear regret in present times for fighting with her just before she died.
Would Hit a Girl: Not necessarily brutal, but he has slapped his sister, because he thought she was telling horrible lies, and Nana, who suddenly attacked Nyu, in the face, and he hits Nyu with a slipper because she is going to, er, rape Nozomi.
Kouta's cousin, who is around 19 years old and planning to attend the same university as Kouta. She moves in with him at the inn after having not seen him in many years. Having had a crush on Kouta since childhood, she still harbors strong feelings for him, and is openly jealous of Kouta's attention to Nyu, to the point of being irrational.Despite her brash tendencies, Yuka is geniunely as kind and caring as Kouta. Though she is hesitant and reserved, she is accepting of Kouta's decision to use their inn to shelter those in need.
Clingy Jealous Girl: In a grating manner as well. People tend to dislike her for this... while forgetting that Lucy can be even clingier. At least Yuka would NOT try to kill Lucy, whereas Lucy HAS used her vectors to push Yuka down and started her Roaring Rampage of Revenge because she was jealous of her.
Cool Big Sis: Arguably. She tries, bless her heart, but it doesn't necessarily work.
Cross-Popping Veins: Happens to Yuka twice, once when Kouta was about to mention that her cooking wasn't special, and when his little sister teases her in the flashback.
Expy: Yuka's design looks very similar to characters from Lynn Okamoto's previous works: Sara Wyoming from Elfenlied and Kasumi from Digitopolis, especially when he redraws them. Yuka's design becomes the basis for Nono Nonomiya and Ryouta Murakami, especially the former looks identical to her. It should be noted that Sara, Kasumi, Nono and Ryouta are all main protagonists of the respective works.
First Girl Wins: She is the first girl Kouta met in the story, in both, his backstory, and in the main story. They eventually marry and have a daughter.
First Kiss: With Kouta. In the manga, it's a French kiss.
Kissing Cousins: She is infatuated with her cousin Kouta. Kouta is also attracted to her, as the temple scene indicates, but then there's Lucy/Nyu muddying things up.
Lets See You Do Better: During the festival flashback, Yuka is constantly breaking the clay animals at one of the stands. Kouta says that she's terrible at it, so Yuka tells him to do it if he's so awesome at it. Then he does and manages to get the animal shape out of it, and she promises to get better at it.
Love Confession: When Yuka confesses to Mayu how jealous she gets whenever Kouta pays attention to other girls, Mayu gently asks Yuka if maybe the reason she gets so jealous is that she loves Kouta. Yuka tearfully admits she's right.
Team Mom: As the older of the girls, she is sometimes referred as the "mother" of the group in the anime.
Tsundere: Type B. She's usually a sweet girl, but she can be violent and harsh towards Kouta.
Woman Scorned: What? Kouta can't remember a promise due tohis sister and father getting violently murdered in front of him about twenty minutes after making said promise in some rather guilt-inducing circumstances? That bastard. Guess I have to kick his ass now. Granted, she has no idea that he repressed his memories of that day, and she regrets her earlier reaction once she figures this out, but still.
A 14 year old girl, neglected by her mother and a victim of sexual abuse by her stepfather. She eventually runs away and is homeless at the start of the series, living on the beach and subsisting on bread crusts from a local bakery under the pretense that they are for the small puppy, Wanta, that accompanies her. She ends up living with Kouta and Yuka as her legal guardians, and later befriends Nana and tries to take her under her wing.
Tropes associated with Mayu:
Abusive Parents: Her stepfather sexually abused her, and when she told her mother, the latter's reaction was to slap her and express jealousy of all the "attention" the former gave Mayu. Later, her mom gives up custody of her to Kouta and Yuka without a fight.
Attempted Rape: She was very nearly raped by the Unknown Man in the manga.
There's also when she hears about Lucy, she doesn't believe that the person she knew as Nyu could be a sadistic killer and saves her during her 2nd fight with Bando, after which Lucy tries to kill her.
Does Not Like Men: She follows this to a degree; the manga implies that her traumatic experience with her stepfather has soured her on men in general, and finding Kouta in the bath groping Nyu doesn't help. Ironically, she appears to bond most closely with Bando, who generally treats her like crap, yet saved her from the Unknown Man.
Happily Adopted: By Kouta and Yuka. They later track down Mayu's mother, who signs over legal guardianship to them without any complaint (she didn't want Mayu in her life anyway). Afterward Mayu is seen living quite happily with Kouta and Yuka, and says she considers the two of them to be her real family.
Interrupted Suicide: Possibly implied in the anime after running away from home. She was about to walk into the ocean, but stopped after she heard a puppy barking from the beach; she adopts the puppy and names it Wanta.
Let Them Die Happy: When Bando lies dying after Taking the Bullet from Lucy for Mayu, he asks what happened to Lucy. Before Nana can tell Bando she got away, Mayu says that Bando's last bullet killed her, so he can die believing he finally got his revenge on Lucy. Subverted when Bando turns out to be alive in the last chapter.
Plucky Girl: Mayu's got bravery to spare when she's pushed to it, as she shows when Bando tries to threaten her into revealing Nyu's location and she has the presence of mind to call him out to his face.
Heroic Dog: Both supported and subverted in Mayu's dog Wanta. His loyalty to Mayu (even over a woman who claimed to be his true owner) and the others is stellar. But like his human and otherwise friends, his ability to save them is way limited, and he is nearly killed by the vicious Unknown Man.
Precious Puppies: He's a little, adorable white puppy and one of Mayu's best friends.
Team Pet: He's the pet of the Maple House citizens.
Also known as Number 7, she is a young Silpelit (Diclonius born from a human) girl who has the physical appearance of being 14 years old. Most Diclonius babies are euthanized at birth, but Nana was one of a handful kept alive for use as a test subject. As a result she has spent her entire life in the Diclonius research facility. Nana can be seen as the exact opposite of Lucy. While Lucy's default personality is serious and cold, Nana's is fragile, friendly, and kind. Nana's default personality is very similiar to Nyu and she also has an endearingly immature knowledge of the world.Nana was a stand-out subject among the Diclonius for being able to effortlessly repress her murderous instincts. Accordingly, she has never used her vectors to harm humans (or anything for that matter). Chief Kurama sees her as his daughter and cares very much for her. In the end, Nana and Kurama are regarded more instead as a couple with Nana referring to herself as his 'wife', as Kurama couldn't accept Nana as her daughter after his real daughter's death.
Tropes associated with Nana:
Adaptation Dye-Job: Her hair is purplish-blue in the manga, but is purplish-pink in the anime. Also her eyes were green rather than rose-pink.
Adaptational Wimp: In the anime, she's completely curb-stomped by Mariko. This also happens in the manga, but there Nana fights back and gets even the upper hand. Actually, she wins and nearly kills her if Kurama has not appear there.
An Arm and a Leg: The end result of her fight with Lucy ends with Lucy tearing off all of her arms and legs one by one.
Beware the Nice Ones: The few times said cutie-persona/psychological-defense-mechanism is broken through. During Nana & Bando's first meeting on a moonlit beach, Bando pushes her too far and she snaps on him, gaining the same dead look in her eyes that Lucy almost-constantly has and trying to kill him (and coming very close) until a .50-caliber bullet grazing her head knocks her back to her senses. Later in manga Chapter 74, the Unknown Man threatening Mayu and casually killing Number 28 right in front of Nana is enough to set her off again. Unfortunately, he blasts her before she can attack, taking her out of the fight.
Break the Cutie: An extremely clever inversion. It's explicitly stated that her "Cutie" persona is a psychological defense mechanism that she developed as a result of the universe's constant attempts to break her.
Can't Catch Up: Despite smarts in battle and ever-increasing savvy, she has a good showing but always gets curbstomped by opponents.
Cassandra Truth: Nana knows about Nyu's alternate personality Lucy, but no-one else believes her.
Curb-Stomp Battle: Finds herself at the end of these, most noticeably against Mariko. However in the manga she often ends up returning the favor, often to the person who was just beating the living crap out of her as Mariko can attest.
She also casually beats the clone of Mariko, Barbara, senseless until the latter takes Kurama hostage.
Lethal Chef: Given that she was raised in a lab, this isn't all too surprising (especially in the OVA: first, she burns some in a pan, then she's too enthusiastic cutting the lettuce, her prosthetic arm comes of and the knife nearly hits Mayu).
Made of Iron: She takes a bullet to the face from Bando, and all it does is knock her back to her senses and freak her out from the sight of the blood.
Money to Burn: A variation; she's so clueless over the concept of money that she uses the yen Kurama left her with for kindling.
Morality Pet: To Chief Kurama. She is kind of a substitute for his own mutant daughter.
Ms. Fanservice: There are TONS of scenes of her naked throughout the series.
In the 13th Episode, she's wearing nothing but Kurama's jacket.
Mundane Luxury: To someone who was raised as a test subject like she was, a simple hot bath is a luxury.
My Name Is Inigo Montoya: Nana invokes this one constantly, usually just after she's been dealt a severe injury in combat, with "This doesn't hurt at all!" Also usually, the trope is horrifically subverted. Occasionally the reverse occurs, and Nana goes on to triumph in the encounter (albeit, usually, temporarily).
No Social Skills: She knows absolutely nothing about the world outside the complex where she used to live, to the point of burning a "bunch of papers" that turned out to be money. And being gullible enough to believe that the money when kept together would attack her in her sleep.
Lucy keeps dismembering her limbs even if she's already defeated.
Receives a brutal one from Mariko. In the manga however, Mariko makes the mistakes of threatening Kurama. Nana's response is to punch her senseless and disable her vectors before threatening to kill her.
Not So Different: Nana can act like a "normal" Diclonius when the situation calls for it.
Only a Flesh Wound: Subverted in her battle with Lucy; after she gets her leg and fingers chopped off, she insists it doesn't hurt... only to drop the tough girl act and scream in agony when Lucy takes off one of her arms.
The Pollyanna: Admirably and heroically. Under ridiculously brutal circumstances that turned other Diclonii into killers. Choosing not to be one of the series' unstoppable killing machines, Nana maintains an unshakable positive outlook, anchored by her belief that everything will be OK when she can be with papa again.
Power Nullifier: She can use her vectors to temporarily disable other Diclonius's vectors.
Redemption Equals Life: If you count simply being a Diclonius as a state in dire need of redemption, Nana definitely qualifies. She is one of the kindest characters in the series, meaning she staunchly rejects the inherent, ingrained desire to eradicate all humans. She never takes a single life throughout both the anime and manga and is amply rewarded by being the only Diclonius to survive the manga.
Rocket Punch: Bando lured her on the beach, where she couldn't use anything as a projectile to throw at him. She used her artificial arm. She later uses her arms this way again.
Took a Level in Badass: After her defeat by Lucy, Nana becomes better in battles. Often because of her Artificial Limbs she can throw as projectiles and other quick surprise attacks. Also, in every battle with Mariko and her clones, Nana gets the upper hand at least once per battle, depending on the occassion.
Too Incompetent to Operate a Blanket: Raised in a lab, and thus, unable to even cut a cabbage with an ordinary knife. When she first meets Mayu, she is completely clueless over the concept of money and uses the yen Kurama left her with for kindling.
Tranquil Fury: Bando makes the exceedingly foolish mistake of pushing Nana too far the first time they meet, and she lapses into this: he even gets a flashback of Lucy looking at her like this.
Wife Husbandry: In the manga, it's implied she and Kurama will get married in the future.
Younger than She Looks: Silpelits age at about double the rate of normal humans. Nana looks 14 and is really only around seven years old, she also ACTS like her real age too.
A 15-17 year old girl who's Yuka's best friend and kohai, she aspires to become a famous opera singer like her late mother. However, her father does not approve of her dream, due to her being the only heir of his business, and also because she has a throat defect that will eventually make her lose her voice if she strains it too much.Due to Dad's rather... violent opposition of her dream, Nozomi developed a psychological trauma that makes her wet herself whenever she becomes too nervous. Despite this, she tries to get into a music high school, secretly training at the Maple Inn, which Yuka invited her to, during her free time and moving there permanently after getting accepted.
Tropes associated with Nozomi:
Abusive Parent: Her father abused her for disobeying him. Though it turns out that he did not want her to become an opera singer like her mother, who lost her voice and commited suicide, especially since Nozomi has the same throat defect as her mother.
Adapted Out: Surprisingly few people are aware of Nozomi's existence. Despite being a main character, she was written out of the anime.
The director of the Diclonius research facility. He is a repulsive, power-hungry man lacking any sense of morality and will do whatever it takes to achieve his goals. He is from a long line of Diclonius ancestry that has been watered down by inter-breeding with humans. As a result, he has no vectors and much smaller horns on his head. The aim of him and his son is, in part, to replenish their bloodline with the Diclonius they are experimenting on (of which Lucy was the first specimen capable of reproducing) and consequently become "kings" of the new race.
Tropes associated with Director Kakuzawa:
All Men Are Rapists: A very creepy and disturbing example, as he impregnated Lucy's mother, despite ripping off her lower body half, but keeping her sexual organs on the upper half.
Asshole Victim: Lucy kills him, one of the worst characters in the series.
Batman Gambit: Starting immediately after the point where the anime cuts off, Kakuzawa initiates the second part of his plan: a missile launch with the Diclonius virus that would spread into the Japanese population, and, later, the world; in other words, the population of Japan would have their future children Diclonius, without them knowing of it. An attempt to actually stop this from happening does not work, and the gambit proceeds as planned. It would have worked if it wasn't for Arakawa and her knowledge of the Diclonius virus, so it gets foiled later on. The rest of the manga is spent attempting to make sure the scenario does not proceed into even worse territory.
Big Bad: The main antagonist of the series. Definitely moreso in the manga.
The Chessmaster: Manga only. Kakuzawa makes numerous plans to achieve his goal, from Diclonius virus missiles, to his goddess daughter Anna to a male Diclonius. Things seem to fall into his very hands and he runs circles around those trying to stop him. If it wasn't for a combination of unforeseen circumstances, most notably Arakawa's vaccine, he would have won even after being killed.
Dirty Old Man: He misuse Shirakawa as his sex slave and is a very creepy rapist. And his youngest son, he male Diclonius is born to impregnate his half-sister Lucy. Yes, this man wants a girl in her late teens to be pregnant as soon as possible.
Equivalent Exchange: He believes that Kurama must trade Mariko's life, which is Kurama's daughter for working with him.
A human has no more than two hands. To take something, one must drop what one's holding.
Idiot Ball: His plans involve making it so that all children except Lucy's are born slipelits, which are sterile, thereby reducing the Earth's population to one breeding pair (Lucy and himself) plus his male Diclonius son, which will almost certainly result in extinction of the Diclonii as well even if Lucy cooperates.
Karma Houdini: In the anime, in addition to barely getting any screen time, he never faces a bit of danger and is free to gleefully continue his abhorrent research facility.
Large And In Charge: According to the full-cast shot in the last chapter, he is taller than the rest of the cast by a notable amount.
Macho Masochism: Doctor Nousou has at one point developed a way to control the violent silpelites via brain chips, and, when prompted by Director Kakuzawa, demonstrates their complete obedience by ordering one of them to stab herself in the arm. Kakuzawa's reaction? He pulls his gun and shoots himself in the hand, remarking disappointedly that pain is no guarantee for obedience.
Mole in Charge: He half-heartedly puts up a front of wanting to protect the human race from the diclonii, the stated purpose of the research facility he runs, while really wanting the diclonii to wipe out and replace humans.
Only One Name: In contrast to the other Kakuzawas, his first name is not revealed.
The Reveal: During his final confrontation with Lucy, it is made known that his family were never true Diclonius, merely Humans with a minor genetic mutation who invented legends and eugenic myths to cope with the persecution they faced in medieval times. The strife he caused our heroes and the world takes on a whole new light.
Slasher Smile: Pulls off a few. Despite this most of his expressions are actually quite stoic.
The Stoic: More so in the manga. A few hammy speeches and smirks aside, he always remains calm and collect only ever showing the slightest surprise a very few times.
The Unfettered: His goal is to wipe out the human race, replace it with the Diclonius, and be worshiped by them as their new "God".
Utopia Justifies the Means: His goal is to destroy the human race and produce more Diclonii using Lucy, the only fertile female Diclonus, to replace them. He doesn't want to do this for any moral reason, though, but only so that in 100 or 200 years he can be worshipped as the god of the new species.
Voiced by: Osamu Hosoi (JP), Jay Hickman (EN)
The chief of research of the Diclonius children in the research containment facility. He is also the surrogate father of Nana and biological father of Mariko. His wife died from when she tried to stop him from killing their daughter shortly after she gave birth to Mariko.Kurama was initially respected for his stern, no-nonsense attitude and his devotion to his job, in spite of the horrible atrocities that were being carried out. However, recent events cause Kurama's ironclad devotion to waver...
The Heavy: Why does Lucy do what she does? A friend (and her only one) took a bullet for her not knowing Lucy could deflect it so Lucy gave herself in to try and save the friend when Kurama offers to help if she comes quietly. Later Kurama flatly informs Lucy the friend died. She now wants to make him suffer.
In the anime, merely informing Lucy her friend died was enough to set her sights on Kurama. In the manga version, Kurama twists the knife by casting aspersions on the girl he killed, and saying that all this was Lucy's fault for not surrendering and the Diclonius' refusal to co-exist with Humans. Needless to say, this inverted accusation has no appeal for Lucy, and explains her single-minded hatred all the more.
Karma Houdini: He appears to be one anytime he confronts Lucy. While the latter would kill just about anyone without a second thought, she never attacks him and at one point even pats him on the back with a bloody handprint from one of her vectors. The reason for this is because when he had Lucy surrounded with a female friend she made after Kouta, one of his men accidentally shoots the girl. Kurama promises he would do everything in his power to make sure she survived if Lucy turned herself in. Since she didn't want to lose yet another friend, she agreed to it. But later Kurama tells her that the girl died from her wound. So Lucy promises to make him suffer the same way he made her suffer, hence why she doesn't kill him, but merely wants to destroy everything around him.
Living Emotional Crutch: To Nana, who could only withstand all the experiments conducted on her by becoming attached to and wanting to please her "papa".
Necessarily Evil: Having to sacrifice children and adult women for the sake of saving the human race.
The Needs of the Many: He's willing to terminate innocent children and not-so-innocent adult women alike, for the sake of saving the human race.
Nominal Hero: In the anime. And in the manga for a bit by disowning Nana.
Offing the Offspring: Kurama was initially in charge of terminating Diclonus children because he was the only one who could do it with no signs of regret. That is, until, his own daughter Mariko turns out to be one as well...
Zigzags. Ultimately subverted in the anime, when Kurama dies with Mariko because Mariko explodes rather than him doing anything to her. Eventually played straight-ish in the manga, though Kurama only kills a clone of Mariko and not the real article, with the clone vehemently insisting on not being treated as Mariko.
Parental Substitute: To Nana. However, at the end of the manga, Nana and Kurama are regarded more instead as a couple with Nana referring to herself as his 'wife', as Kurama couldn't accept Nana as her daughter after his real daughter's death.
Expy: Her appearance strongly resembles Aoki, the heroine of Lynn Okamoto's Flip Flap, his first drawn manga. It's not obvious because of Art Evolution, but the redrawn picture of her looks very much like Shirakawa.
Reverse Mole: Preceded the Agent in this regard, sending enough information to her superiors for them to realize the gravitas of the situation and send in the second.
Sex Slave: In the manga, she's a Sex Slave to Director Kakuzawa to get information from him.
Sexy Secretary: To Kurama. Director Kakuzawa even use her as a sex slave.
Uriah Gambit: Sending Mariko in to fight Lucy was her idea. They were counting on Mariko winning, and even if she didn't, it wouldn't be a total loss. The Director accuses her of doing it to destroy parts of Kurama's past life so he'll let it go and move on. Her reasons for doing it are likely a combination of that, risking less human lives, and trying to divert suspicion from her Reverse Mole Status.
Yandere: In the manga, it was her idea to implant bombs within Mariko's body, not Kurama, who was unaware of it. The reason? It was a child from another woman. Shirakawa is not even his lover.
Adaptational Villainy: Manga Isobe was a troubled individual who tried to see the differences in Diclonius. His own niceness in fact is what got him killed. Anime Isobe not so much and comes off as another typical arrogant human.
Although, the first episode features a man with a brown suit who looks more like the manga-Isobe; apparently the staff of the anime studio changed their mind. It's also possible that they transfered Isobe's role into a new unnamed anime character.
Killed Mid-Sentence: In the anime, when Isobe attempts to shoot Nana, but he is killed by Lucy.
"You're the only one left. Think of the reward—" (gets decapitated)
No Good Deed Goes Unpunished: Tries to save Mariko from blowing up when he thinks she's had a change of heart. She plays with his emotions and after getting what she needs, callously beheads him.
No Name Given: In the anime. The manga reveals his name after he died.
A researcher working alongside Professor Yuu Kakuzawa to find a vaccine for the Diclonius virus.She, along with Kouta, ends up seeing Professor Kakuzawa's mutilated body. She reports to Chief Kakuzawa what she's seen, but he doesn't intend to let her off scot-free, and threatens her with death lest she take up the rest of Professor Kakuzawa's research.In the anime, she's basically only there for comic relief, but in the manga, she plays an extremely important role as the story progresses on.
Tropes associated with Arakawa:
Action Survivor: At the end of the manga, she survives the riot of the clone Silpelits.
Chekhov's Gunman: Manga only. She ends up finally creating the Diclonius vaccine.
Girlish Pigtails: She wore two braids in her middle school life. The boys view her as unfeminine and ugly, though.
Hot Scientist: She actually looks pretty good. She has a lot of Panty Shots and later goes only with a shirt and a panty.
Identical Stranger: A weakend Diana mistakes Arakawa for Nousou, probably because of their similar hair style. This actually saves her life and allows her to command Diana.
Mad Scientist: Arakawa starts out as only slightly eccentric when she has to take over his work. Being practically locked in in a basement room on a small remote island and working alone for weeks really tooks it's toll from her.
A young researcher who is Mariko's foster mother and communicates with her per speaker and monitors. She claims to love Mariko like she's her real child, but Saito is brutally murdered by her, though she manages to blow one of Mariko's arms off.
Tropes associated with Saito:
Beware the Nice Ones: She seems to be a sweet and nice woman. But in the verge of death, she pushes one of Mariko's bomb buttons.
Cruel and Unusual Death: Her death is more graphic in the anime, when her torso explodes and her organs and bones are flying everywhere.
Dying Moment of Awesome: Despite losing the lower half of her body, Saito manages to push the bomb button and blows Mariko's right arm off, just before she dies.
Good Parents: Played with. She's introduced as a potential first good parent in the series, but when Mariko decapitates her, Saito blows Mariko's right arm off, showing that she didn't love Mariko that much.
Averted later in the manga, when Kurama's assistant Isobe learns that Saito manipulated Mariko with the lie that neither birth parent wanted her, when her mother definitely did, and her father made a devil's deal to keep her alive.
The daughter of Director Kakuzawa, who is turned into a "goddess" with precognition powers.
Tropes associated with Anna Kakuzawa:
Anti-Villain: Type IV. If it wasn't for her father, Anna would probably be one of the sweetest characters in the manga.
Black Sheep: The only member of the family who has a low intellect and no talents. Her human form only.
Eldritch Abomination: A massively engorge brain several tons and capable of predicting the future. Ironically more Eldritch than Abomination and ultimately she returns to her normal form at the end of the manga.
Even Evil Has Loved Ones: She is this to Director Kakuzawa and vise versa. In fact the reason she helps her father is out of love and a desire to be useful to him.
Evil Genius: Subverted. While a genius in her goddess state, Anna can hardly be described as evil (At least not in comparison to her father or some of the other questionable people) and only wishes to help her father out of a need to support him and prove herself. Ironically this was subverted entirely in her human form where she is neither evil nor a genius.
Redemption Equals Life: Played with, in the end Anna does nothing to actually redeem herself. However at the same time out of all the antagonists she is perhaps the least evil and thus remains he only Kakuzawa to survive the end of the manga.
Seers: Her goddess form has precognition powers. Actually it's just very complicated and long math.
A minor manga-only character, a man clad in a black trenchcoat and wide-brimmed hat, with opaque sunglasses and greasy-looking hair. At first appears relatively civil, he soon reveals his true colors as one of most horrifically evil bastards, if not the most evil, in the entire series. A brutal, heartless, Hidan-level sadist, rapist, and all-around not very nice man, he delights in causing pain and suffering, especially in Diclonius and/or teenage girls.
Tropes associated with the Unknown Man:
Abnormal Ammo: Let's just say that heavy spiked balls coated in potent toxins isn't exactly what you'd expect a crossbow to fire.
Agony Beam: A low-tech variation, in the form of a crossbow that fires spiked metal spheres coated in a toxin that causes horrible, cripplingly agonizing pain to those it hits. Bites him in the ass - literally - during his fight with Bando.
Basically the most repulsive parts of Alucard and Randall Flagg rolled into one humanoid mass; combining the looks and personality (Minus the Dirty Coward part) of Alucard and the sheer wickedness and depravity from Randall Flag.
Judging by his brief appearance, high memorability, and specialized weapons within the series, he could also be an Expy to Boba Fett, whose screen time in the first trilogy totaled all of ten minutes. Fett, though, is usually shown to have a deep sense of honor and morals, something Unknown Man obviously has no traces of at all.
Even Evil Has Loved Ones: He really loves Alicia, Barbara, Cynthia and Diana. He's ultimately killed by Barbara when he removed the mind-control device of her.
Gender Flip: His appearance looks very similar to Arakawa. He has a similar hair style like her, just having light hair and mirrored bangs. This becomes a plot point, when Diana mistakes Arakawa for him.
Karmic Death: After removing the mind-control device of Barbara, in hope that she really loves him as a father, she beheads for all the experiments he did to her numerous failed sisters.
That's an Order: He orders Alicia and Barbara to let him die so they would survive and could capture Lucy. They refuse to do so. While Alicia dies, Barbara manages to save him, and Lucy is captured thanks to Cynthia and the Agent.
Cry Cute: She cries before the Diclonii seemingly kills her and she says she does not want to die.
Disney Death: She's surrounded by Diclonii, and the view point shows a Gory Discretion Shot, but she shows up later, no worse for wear, because the ground had given way and she fell into an underground cavern.
Genre Savvy: She recognizes that removing the mind-control device from the clones leads to dangerous things (See Nousou's entry). So when Arakawa does it, she quickly put it back in right before the clone went all Ax-Crazy
Hidden Depths: Introduced as a replacement for the former hunters (the aforementioned Bando, and the Unknown Man), and at first acts as a quieter and less sadistic hunter. Eventually she's revealed to be a government agent sent to shut the facility down, she's also quite the Determinator, and shows she's willing to die if it helps to save humanity.
Not So Stoic: Stays behind to face certain death so Arakawa can escape with the Diclonius vaccine. Starts crying as soon as Arakawa is gone.
Shoot the Dog: When the security forces break into Kouta's house, they quickly, and violently subdue the occupants, with The Agent Pistol Whipping Kouta to prevent him from interfering, and warning him not to try anything. When Nozomi has her throat crushed, Kouta grabs a gun and threatens Nousou, the Agent casually shoots him in the chest. The shooting was necessary to both save Nousou from disfigurement and possible death and to allow her to complete her mission, to save the world from the Diclonius faster, and without raising suspicion.
Also known as Number 35, she is a young Silpelit girl who is the biological daughter of Kurama. She is regarded as the most powerful of the Silpelits, possessing 36 vectors each with an approximate range of 11 meters in the anime (the number and range is much higher in the manga).After her mother's Death by Childbirth Mariko was imprisoned as an infant and raised inside a steel container with human contact consisting of nothing more than a scientist acting as a sort of foster mother Saito through speakers and monitors. Her physical impairment is seen in her atrophied limbs as she moves around in a wheelchair. Despite the environment she was raised in, she is relatively well developed psychologically (for a given degree of "psychologically"), unlike Nana. She is extremely homicidal and sadistic, and enjoys torturing and dismembering her victims. However, her personality is not blatantly evil: she is only having fun, and the pleasure she gets from it is equivalent to a child playing with toys, not really noticing the differences.
Blank Slate: In the manga, after being flattened by a huge-ass missile, Mariko temporarily takes on a Nyu-esque persona, even down to only being able to say "Myu". She snaps back to normal when Lucy shows up.
Calling the Old Man Out: In a rather emotional scene in the manga, she berates Dr. Kurama for treating Nana as his daughter while allowing Mariko herself to be imprisoned in a dark and lonely room with almost zero human contact for her entire life.
Cloning Blues: Only in the manga. Has a terrifying effect on an already beyond-broken Kurama.
Creepy Child: A five years old girl, who happens to be the most dangerous Silpelit and is Ax-Crazy like the rest.
Evil Cripple: She has spent most of her life in isolation and has extreme atrophy in her legs, so she has to get around in wheelchair.
Explosive Leash: Taken to an extreme. She has multiple bombs planted in her body set to go off every 30 minutes if a specific code does not get constantly transmitted. It was set off once when she started going out of control, and was also used to keep her under control, since she couldn't use her vectors if she was in that much pain.
Freudian Excuse: The reason why she became evil is because she's captured in a dark cage since her birth and is left alone by her own parents.
Go Out with a Smile: In the anime, as Kurama takes her for a walk, they tearfully reunite with him promising never to let her go again. The bombs inside of her go off shortly afterwards, killing both of them.
Handicapped Badass: Being wheelchair-bound and having only one (real) arm doesn't stop her from curb-stomping Lucy.
Heroic Sacrifice: In the manga, she charges a now-quite-unhinged Lucy and gets right next to her, allowing herself to be killed just in time for the explosives implanted in her to go off. The explosion knocks Lucy's horns off and causes her to regress to Nyu, thus saving Dr. Kurama from Lucy.
Hime Cut: Mariko wears a lolita style and also seems to have this hair naturally. Apparently, this becomes the basis for Kana Tachibana's design, who is an Elegant Gothic Lolita and is portrayed with Mariko's outfit on her character card.
Hoist By Her Own Petard: She throws Saito's torso at the person who is about to push the bomb button. Unfortunately, Saito is still alive at this moment and pushes the button herself, resulting Mariko's loss of her right arm.
A relatively minor manga-only character, 28 is mainly known for the nauseatingly horrific fate she suffers at the hands of the Unknown Man.
Tropes associated with Number 28:
And I Must Scream/Fate Worse Than Death/Cruel and Unusual Death: After suffering as a lab rat in the research facility all her life, she is raped by the Unknown Man, has everything below her torso amputated and her vocal chords removed, is trapped in a cramped container, which regularly injects a neurotoxic drug directly into her spine which keeps her in constant agony so that she can't use her vectors, and she only has 3 more hours to live. All so that the Unknown Man could use her as a radar to find Lucy. When he finds Nana instead, he kicks over her container in anger, which finally kills the poor girl. Earlier, when Nana had sensed her presence, she kept hearing a voice crying out, begging for someone to kill her. Sweet mother of God...
The Voiceless: She doesn't get any spoken lines before the Unknown Man first gets his hands on her, and afterward she can't speak because the bastard ripped her vocal chords out.
Alicia, Barbara, Cynthia & Diana
Alicia, Barbara, Cynthia & Diana
The four are the only successful clones of Mariko, created by Doctor Nousou, but they are physically older than their original. Each of them have a mind-control device inside their forehead that prevents them from going amok and makes them peaceful. Nousou has perfect control of them and they listen only to him, but sometimes they do not if they try to save his life. The clones are used to capture Lucy.
Tropes associated with them:
Alphabetical Theme Naming: Their names start with a letter from A to D: Alicia, Barbara, Cynthia and Diana. Furthermore, their names end with an A.
Anti-Villain: Due to the mind-control devices, their evilness is surpressed and they are sweet girls who are working for the villains. Barbara subverts this later, and Diana for a few seconds.
Cool Helmet: Each of them wear helmets similar to Lucy's, but the number of eye holes depends on the one who wears it. Alicia has one on both sides, Barbara has two, Cynthia has three, and Diana has four.
Cry Cute: Diana cries after stabbing on her arm. Cynthia cries when she's ripped apart by Lucy, and Barbara and Alicia cry because of that event and later when they try to save Nousou.
Defusing The Tykebomb: After his near death experience, Nousou considers whether the girls could live a normal life or not.
Determinator: Alicia and Barbara do not give up to save Nousou, regardless of the pain the have to feel or the danger they in there.
Does Not Like Shoes: For some reason, Barbara does not wear shoes when she's in hospital with Nousou, resulting that she goes (and "flies") barfooted after she leaves it.
Died in Your Arms Tonight: Cynthia dies in Kurama's arms, who mistakes her for Mariko. Coincidently, it is night when it happens.
Expendable Clone: Ordering a Diana to stab herself in the heart to prove a point isn't the worst thing done.
Game-Breaking Injury: Nousou orders Diana to stab into her heart. She gets better, thanks to a replacement heart, but this injury makes her useless for the mission to capture Lucy, that's why she stays in the labor. This is fortunate for Arakawa, who is later saved by her.
Cynthia manages to break one of Lucy's horns, despite being cut in half.
A weakened Diana manages to kill several other Silpelits before being killed herself.
Heroic Sacrifice: Alicia and Barbara disobey Nousou's order to capture Lucy or run away, but they decide to save him from being crushed by a helicopter. Lucy uses the opportunity to attack them with objects, since she is out of their range. Alicia gets killed by her, and Barbara still disobey Nousou and jumps in front of him to tear the helicopter above him apart, since the clones' vector's ends are weaker.
Hime Cut: Like Mariko, they have this kind of hair cut. Their fringes also hide the mind-control devices in their foreheads.
Hope Spot: Diana becomes one for Arakawa and the Agent. But not for long.
Killed Off for Real: All four of them die during the course of the story, but under different circumstances. Cynthia is cut in half and dies a few minutes later after that. Alicia is beheaded by Lucy before Cynthia finally dies. Barbara is shot in the head by Kurama. And Diana is beheaded by one of the random clone Silpelits.
Not Quite Dead: Cynthia is not immediately killed after being in cut in half by Lucy. With the help of the Agent, she is able to break one of Lucy's horns. Unfortunately, Kurama finds Cynthia, mistaking her for Mariko, and she dies in his arms.
Younger Than They Look: They are only a few months old at most, but they look physically older than Mariko, being in their puberty. Since Silpelits age double as fast as humans, and clones of in general age faster than their originals, this combination justifies this trope.
The Male Diclonius
The Male Diclonius
The only male Diclonius and the second one who is not a Silpelit. He's the son of Director Kakuzawa and Lucy's mother, being Lucy's half-brother, who is specially born for impregnating her. He also has a mind-control device in his forehead and is controlled by his father.
Tropes associated with the male Diclonius:
Brother-Sister Incest: He's born to impregnate his sister, so the pure Diclonii race won't extinguish, and Director Kakuzawa becoming god.
Child by Rape: Director Kakuzawa ripped Lucy's mother's lower half off, but kept her sexual organs, so he can impregnate her.
An operative for the National Police Agency's Special Assault Team. Although he is technically human, he is as homicidal and apathetic to other people as the worst Diclonius are. He is incredibly skilled in combat and widely-regarded as a lethal and bloodthirsty soldier.
Tropes associated with Bando:
Adaptational Villainy : While a Jerk Ass, Bando in the manga was a badass with redeeming qualities to him and character development. The Anime decided to get rid of anything that could make Bando likable while adding more things to hate. The end result was a character who at his best was still worse than Manga Bando at his worst.
Bad Ass: Easily one of the most badass characters in the series. At least in the manga.
Badass Boast: Offers some subtle but still cool lines in the manga and backs up every single one.
"What are you surprised about stupid? Didn't I tell you that I can never die?" After coming back at the final chapter of the manga after being cut in half by Lucy.
"You dumbass! Me alone is plenty for the likes of you!" Lucy mockingly tells him and Nana to come at her together. He gives this line and avoids all of her attacks and proceeds to beat the crap out of her.
He tries to give one in the anime. "You think I need a gun to kill you? I'll do it with my bare hands." Which might have been incredibly badass had he not been a broken bleeding mess on the ground whom Lucy obviously didn't see any threat and was unable to back his words up.
Takes on several Diclonius including Lucy (twice) Nana and Mariko in the manga and holds his own using nothing but his skills and some heavy bullets and comes close to winning a few of them as well. Not even getting torn in half will stop him.
In the manga at least, he, after surviving multiple encounters with Dicolonii, learns how to dodge vectors.
He also nearly manages to beat Lucy in his 2nd fight with her, losing because the Unknown Man got in the way, and then because Mayu got in the way.
Also when facing the Unknown Man, he gets hit with one of his toxic spiked balls, and he endures the pain and rips it out despite being hooked into his skin with barbs.
After getting his ass handed to him by Lucy early on, he completely cleaned up the beach in order to make sure Lucy had nothing to attack with, figured out her range of attack, and got modified Desert Eagles that fired rounds too heavy for Lucy to block or at close range knock away.
His crazy preparedness actually works against him in the manga where his attempt to blind Lucy with a flash grenade and tear gas worked against him when the bright flash kept most of the gas from entering her eyes. Though even she admits that if it wasn't for the Unknown Man, he'd have won.
He gets the short end of the stick when he meets Lucy.
He gives one to the Unknown Man, even though he had his crossbow and Bando didn't use a gun.
Having been prepared this time around, his second fight with Lucy in the manga ends with him stomping her face into the ground and nearly killing her twice. Unfortunately, people like to get in the way.
Cyborg: He gets a prostethic arm and artificial eyes.
Disability Superpower: His prosthetic arm allowed him to remove a spiked ball from his body during fight with the Unknown Man.
Determinator: Through a combination of technology and sheer badassery, Bando walks off stuff that would kill most people. These include getting in order, his legs shot up, one arm ripped off, the other arm snapped, both eyes gouged out, the second arm ripped off and getting bisected. In short, by the end of the manga Bando is basically a head and chest on life support and isn't slowing down.
Grabs hold of a spiked metal ball, which is coated in agony-inducing toxin, out of his body and baseball-pitches it straight into the ass of the guy who shot him with it.
Disney Death: He's cut in half by Lucy. In the last chapter, he's fine and comes back to Mayu.
Heroic Sacrifice: Saves Mayu from Lucy during his second battle in the manga and gets cut in half as a result. Unlike most examples he survives. It also completes Bando's character development in the manga.
Half the Man He Used to Be: Loses his lower half and his left arm (and his right one, though he lost it earlier, and It had been replaced with a cybernetic arm). He recovers, but with a cybernetic lower half (and arms).
Hand Cannon: Bando uses two Desert Eagles chambered in .50AE, and is actually justified in using it: Most handgun bullets bounce off the Diclonius vectors, the heavier and more powerful .50AE round will go right through at a close enough range. The only other option is to use an anti-tank sniper rifle or something equivalent in power.
Handicapped Badass: Blurred vision and a dysfunctional hand doesn't stop Bando from kicking extreme amounts of ass.
Hitman with a Heart: In the manga. Despite his intro as a Psycho for Hire and the other times where he acts the part after, he's not all bad, specially towards Mayu. The anime? Not so much.
Mildly Military: In the anime, Bando has done everything up from threatening other men with guns, to knocking out his own partner to just being a real jerkass overall. Averted to a significant degree in the manga. Bando may say a few threats, but never does more than that.
No-Holds-Barred Beatdown: Beats the absolute crap out of the Unknown Man which culminates in him shoving the Unknown Man's poisoned spiked ball where the sun don't shine.
Pet the Dog: Manga only when Bando is going through his character development. While his overall attitude doesn't change, his actions certainly do. By the end of the manga, its almost surprising that he was a near complete monster at the start of the manga. Some of the things he ends up doing is...
Seeing if Mayu is alright after roughing her up.
Saving Nana and Kurama from an enraged Mariko.
Preventing Kurama from committing suicide and sheltering him.
Saving Mayu and Nana from the vicious unknown hunter and keeping his promise to Mayu.
Sacrificing himself to save Mayu from Lucy.
Pragmatic Villainy: Played With: he claims to clean up the beach because he's preparing for a fight with Lucy, and any and all trash can be used as a projectile. While that is true, he really does hate the litter and wants to keep the beach clean.
Sir Swears-a-Lot: Being the tough guy that he is, Bando curses far more than anyone else in the series. What makes it even more noticeable is that pretty much all the other main and secondary characters either don't swear at all or only do it once in a while.
Staying Alive: He has come back from having one of his arms torn off while the other is broken and having his eyes gouged out by means of cybernetic implants. Later on he is torn in half (by the same character no less) yet returns in the end of the story healthy again (except he's half robot by this point). Somewhat jarring in that he was definitely dead the last time.
Sunglasses at Night: Partially justified, as he set up flash bombs on the beach, and he kept the glasses on, on the off chance he'd get into fight.
Too Dumb to Live: Instead of just ventilating her, he chooses to play around with her first (a "duel"). In the ensuing fight he manages to accidentally awaken her "Lucy" persona and nearly gets killed.
Took a Level in Badass: While hardly weak before, Bando goes through some major changes in the manga after his first defeat by Lucy. His fights afterwards end with him utilizing the knowledge about Diclonius to his advantage, using several good tricks and remaining the only human to fight Lucy twice (and surviving) but actually holding the advantage over her in their second fight and nearly winning.
Took a Level in Dumbass: Zigzagged somewhat in the anime. Ironically while he was taking several levels of badass and character development in the manga, the anime decided to do the opposite. Though he gets stronger weapons and learns about keeping his distance. His fights in the anime after being mutilated usually involved him kicking his opponent while they're down (and then realizing afterwards he shouldn't get too close) and shooting his gun in the general direction of people and yelling a lot. In the end it only makes his anime counter part come off not only as a bigger jerkass than before, but incompetent as well.
Villainous Rescue: He's a psychopath whose only goal in life is to find and kill Lucy/Nyu, but when the Hunter assaults Mayu, he comes to the rescue.
The Unfettered: Anything is permissible so long as he has the opportunity to kill Lucy.
Would Hit a Girl: Most notably on his introductory scene, when he viciously backhanded a woman who made the mistake of approaching him from behind without warning. He outwardly threatens Mayu at one point by citing this trait: see below.
Would Hurt a Child: Despite having some standards, he is still more than willing to rough up Mayu and harrass Nana to get some information about Lucy. He also generally treats both girls like utter crap when he's not saving their lives from psychotic Diclonii like Mariko or Lucy or the even more psychotic Unknown Man.
Death By Child Birth: Not the birth itself killed her, but the following events immediately after the birth caused her death. She bled to death due to the complications she suffered from the birth and operation.
Driven to Suicide: Subverted. Kurama remarks that after attempting to kill his daughter, she committed suicide after seeing it. We learn later on that she had suffered from complications due to the birth because of cancer. She ultimately tries to stop Kurama from killing Mariko and begs him to spare her and ends up bleeding to death due to the complication.
