The Zoldyck Family
- Abusive Parents: Poisoning and torturing their children is completely normal to them.
- Badass Family: Not one of them isn't more dangerous than they look.
- Big, Screwed-Up Family: There're quite a few of them. They have politics. And a few are rather hung up about rank. It's not a healthy mix.
- Blue-and-Orange Morality: Their standards veer markedly off what anybody else would consider normal parameters, even in this series, which is saying something. For all intents and purposes, you can think of their baseline as being somewhere around Lawful Evil or Neutral Evil. But, that's hardly a decent guide and doesn't give you nearly a third of the details.
- The Clan: With a big ol' house in the country, even.
- Dysfunction Junction: Well, what do you expect from a family that has been training children to be killers for generations? Well-adjusted, sociable souls by normal standards?
- Family Business: Which is killing. Bespoke or bulk: it'll be expensive.
- The Family That Slays Together: Puts bread on the table... and, love each other in the weirdest ways possible.
- Family Theme Naming: The five Zoldyck children. From oldest to youngest: Illumi, Milluki, Killua, Alluka, and Kalluto; taking the last syllable of the name of the previous child becomes the first syllable of the next child, and each one also has "llu" after the first vowel; if there were to be a sixth child, their name would logically begin with "Tollu-".
- Fiction 500: To start with, they own an entire mountain and the land surrounding it. They have a cadre of badass butlers who are trained in a special, dedicated school, solely for the purpose of keeping outsiders from bothering them. The amount they charge for assassinations can run into the billions. Who knew assassination was such a lucrative occupation?
- The Ghost: Killua's paternal grandmother, who is shown as a silhouette standing between Maha and Killua in the 2011 anime, hasn't been seen.
- Lack of Empathy: So subverted, you wouldn't believe. Yes, they have major trouble engaging with others on a normal basis. But if you think this means they don't have emotions, you've got another thing coming. They're just... far from normal in how they express what they have.
- The exception to this is Illumi, who preforms many cruel actions and shows none of the Standards most of his family have.
- Love Is a Weakness: Not towards one another but they disapprove of making relationships with people outside the family. Kikyo and Illumi don't like Killua going out and making friends, believing them to be a distraction preventing him from embracing the family business. They also don't allow their butlers to form romantic relationships with anyone on pain of death.
- Leitmotif: "Family of Assassins' Estate".
- Only in It for the Money: Generally, they don't kill anyone or get involved in the affairs of others unless they're being paid to. They also hold no loyalty to their clients and don't let conflicts of interest get in the way of accepting assassination contracts. When the Mafia hired Zeno and Silva to kill Chrollo, he simply hired Illumi, Maha, and Kalluto to assassinate the Mafia leaders before he could be killed, voiding the hit on him.
- Professional Killers: And very, very good ones. If someone hires a Zoldyck to kill you, then you are better off trying to find who and have them killed, so as to cancel out the contract, than trying to defend yourself against them.
- Sugar and Ice: Some seem sweet or kooky on the outside, but are black ice on the inside or when on the job. Some are the classic ice on the outside, but show gooey centers in the right circumstances and only to the right people or things. Some hide active volcanoes under their glaciers. All can give you murderous-intent-induced freezer-burn in microseconds from either mode if you're not careful.
- Training from Hell:
- Every member of the family undergoes this type of training from a young age that increases their strength, speed, and resistance to pain.
- The household staff live in a constant state of training and everything they use is weighted. For example, their clothes can weigh between over 100 to 300 pounds and the doors to the bathrooms weighs well over 1100 pounds.

Zeno's grandfather. He once fought Netero and is the oldest character of the manga.
- Adapted Out: His debut scene is cut out of the 2011 anime remake.
- Gonk: His face looks like a clay Djinn.
- Out of Focus: Appears all of one time in the story, doesn't get a speaking part, and is off on some unrelated assassination mission.
- Really 700 Years Old: He looks incredibly old, but is actually even older than he manages to seem.
- World's Strongest Man: Possibly. Zeno said Netero is the only one who survived a fight against him. He didn't say who won that fight.

Killua's grandfather and Silva's father. For someone his age, he is shown to be a formidable fighter with a sharp mind. His Nen abilities revolve around emitting aura in the form of a dragon.
- Alliterative Name: Zeno Zoldyck
- Badass Moustache: Droopy, but it fits with his "elderly assassin" vibe.
- Came from the Sky: His apparition during the Palace Invasion with his Dragon Dive.
- Colony Drop: His Dragon Dive technique shatters a Dragon Head into countless smaller aura dragons that rain down from the sky.
- Cool Old Guy: Comes across as a bit of a wacky, old coot with a sense of humour when he isn't putting the Game Face on like a champ. Particularly in comparison to his daughter-in-law's total lack of anything remotely resembling flexibility towards new ideas.
- Everybody Has Standards: He makes it a point to never kill anyone unless he's being paid to, remarking that assassination is his job, not his hobby.
- Mythical Motifs: Dragons. His nen abilities revolve around dragon-shaped aura attacks, and he's a powerful assassin from the famed Zoldyck family.
- Never Hurt an Innocent: Despite the fact that he's violent and kills without hesitation, Zeno does not like to harm people that are outside of his contract work. This is demonstrated when he accidentally injures Komugi when he was out to kill the Chimera Ant King.
- Shaping Your Attacks: His nen attacks have the form of a dragon.

Killua's father, who resembles David Bowie. Well, as seen in Labyrinth anyway. Silva is pleasant towards everyone in his family and presumably everyone he hasn't been assigned to assassinate. He forgives Killua for not wanting to follow the rest of the family, much to his wife's dismay. He accompanies his father Zeno to dispatch Chrollo, but Illumi killed the man who ordered the hit, and the two called off the fight. Silva's ability seems to be energy blasts of varying sizes, not unlike those seen in Dragon Ball Z.
- Action Dad: Is Killua's father, and he kicks lots of ass in curbstompy ways.
- Adaptation Dye-Job: Is given white hair in the 1999 anime, but the 2011 adaptation shows him having platinum blonde hair. Though the lighting in some scenes does give the impression of him having white hair.
- Doting Parent: No, really. Despite the many and varied dangers most of his children pose to the world, he sincerely loves them all. He just has a really odd way of showing it.
- Evil Cannot Comprehend Good: Allows Killua to leave the Zoldyck household and travel with Gon after listening to Killua explain his experience during the Hunter Exam. It's later revealed that he didn't do this out of the goodness of his heart, but because he believes that Killua is just going through a phase that he'll eventually outgrow.
- Fanboy: Of Benny Delon.
- Hair Color Dissonance: Although he is commonly portrayed as having platinum blonde hair, various lighting in some scenes gives the impression of him having silver hair.
- Happily Married: Totally in love with Kikyo, and is even willing to allow Killua to walk out of the family's estate with Alluka in his arms rather than risk Kikyo's death-by-wish.
- I Gave My Word: About letting Killua live in his own way for the time being. And, he's sticking to it. There is, however, a catch: he's fully expecting his son to come back permanently, on his own terms.
- Nonstandard Character Design: Looks more like a character from Fist of the North Star.
- Parental Favoritism: To Killua, the chosen heir.
- Punny Name: Silva is pronounced like Silver.
- The Patriarch: The current head of the House. He will definitely listen to advice from the older ones (and, his darling, ever-beloved wife), but what he says ultimately goes (despite grumblings).
- Strong Family Resemblance: Somewhat, Killua is the only one of his sons to inherit his silver hair and blue eyes.
- Tough Love: Oh, boy... yes. One example? Throw your six-year-old son at a gladiatorial tower of death to work his way up to the 200th Floor. Given what can very easily happen on that floor to Nen newbies, and you've got to wonder... Add all the torture, murder, and poison training (and how to endure it) his kids get and it leaves you only one sentence: "What the hell, Silva?". But, it's not done because he hates them, but because that's how Zoldycks grow up and he loves them.
- Worthy Opponent: Sees Chrollo as a target worthy of his full strength.

Killua's mother, who dresses in an elaborate Victorian dress and a sci-fi visor over her eyes. She also talks like a lady from that era. She feels upset that Killua has decided against following in his father's footsteps and becoming a professional assassin. Seemingly as compensation, she trains Kalluto to be subservient. This seems to have failed too, as Kalluto has joined the Spiders.
- Action Mom: A lot more actiony than you'd think, looking at those bandages.
- Almighty Mom: Subverted, she couldn't argue her husband's decision regarding Killua.
- Bandaged Face: She is always seen with bandages on her entire face, suggesting something nasty happened to her in the past.
- Butter Face: She has a fit and nice body for a lady with several grown kids but Bandaged Face and Nightmare Face qualifies as this.
- Dark Action Girl: She is the matriarch of a family of assassins.
- Happily Married: She has a good relationship with Silva.
- Impractically Fancy Outfit: It would appear that a Victorian style dress would be difficult for an assassin so she can run quite quickly wearing it.
- My Beloved Smother: She knows what's best for her precious little Killua and will make sure he follows the family rules, even if she has to send three butlers to follow and/or apprehend him to do so.
- Nice Hat: A damn fine Edwardian style she's got going on there.
- Nightmare Face: Downplayed, in that Kikyo is not, by herself, all that terrifying, but the context within the show makes her appearance unnerving. After seeing her for the first time, one gets the impression that Killua scarred his mother so badly that she had to bandage most of her face and needs her sci-fi visor just to get around. Flashbacks reveal she always wore that visor, leaving the impression that this trope might just be the reason why she wears something so out of place in the setting. What's more, is that she looked even creepier in the first anime.
- One-Way Visor: She has an electronic visor covering her eyes with a mouth microphone. It's shown in a flashback she already had it years ago, so it wasn't caused by Killua.
- Parental Favoritism: Killua is definitely her favorite child. Although, she isn't backward when it comes to doting on any of her other children (even Alluka)... with her own very distinct twists on that concept. Her standards are very likely not to be yours.
- Pet the Dog: After watching Killua's Declaration of Protection for Alluka/Nanika, Kikyo decides to remove the restrictions movement she previously put on Killua.
- Pimped-Out Dress: A large and frilly purple one in Victorian style that goes with that Nice Hat. She can easily turn into Kicking Ass in All Her Finery, whenever she feels so inclined.
- Proper Lady: She certainly tries her best to be this. If she got any stiffer, you'd expect starch to come out of her clothes at every step. She's also not very quick to embrace change.
- Rags to Riches: Originates from Meteor City, the archetypal poverty center of the series. Now, she is a member of the exceedingly wealthy Zoldyck family.
- So Proud of You: Says this a lot to Killua, such as when he gambles her own life on the idea that Silva would sooner allow him to leave the family's mountain with Alluka/Nanika in tow than let her die from a wish he made to Nanika. It showed that he was growing up properly.
- Strong Family Resemblance: It's assumed she has black hair and black eyes considering all of her children except Killua have black hair and eyes, with the exception of Kalluto who has purple.
- Tears from a Stone: In the 1999 anime, when Kikyo cries, it causes her whole visor to blotch out with TV snow static, symbolic of her state of grief. In the 2011 anime, she properly cries, suggesting she wears her visor over impaired/technologically enhanced eyesight.
- Tough Love: Very clingy she may be, but if you think this means nothing but being spoiled rotten with sunshine, rainbows, and puppies, you are very mistaken. What she's inflicted on Alluka is probably also a twisted form of this, in her eyes at least.
- Yandere: Dear Lord, you'd not want to try splitting her up from her hubby. And, heaven help you if you try taking her babies from her... Especially the ones she's a bit disappointed in. She still loves them, way too much to let you think about getting away with it.

The oldest of Killua's brothers, Illumi seems to personally know Hisoka and is on a roughly equal level of power as him. Illumi shows no emotion at all, though he's subservient to nobody except his clients. His abilities, both nen and normal, revolve around needles. He can stick needles into himself to change his appearance, and he can also stick needles into other people to control their movements or, if need be, to deflate them. Illumi planted a needle in Killua that functioned as a Power Limiter and gave him the impulse to back off from fights he wasn't sure he'd win. Killua noticed this during the Chimera Ants arc and removed the needle.
- Aloof Big Brother: It certainly seems this way, but he actually pays a great deal of attention to Killua... more than Killua would like.
- Arc Villain: Serves as the main antagonist in the Chairman Election Arc due to his desire to first kill and later control Alluka/Nanika putting him in direct conflict with Killua and several members of the Hunter's Association sent to stop him.
- Big Brother Bully: He's rough with his siblings, and likes to shove his pins into them so he can control them. For these and other reasons, he is seen as a bully by Killua and others. Of course, he doesn't see himself in that light.
- Big Brother Instinct: Hisoka once playfully suggested murdering Killua to his face. It went over about as well as you'd expect.
- Big Brother Mentor: He was the one who taught Killua to fight and he cares (in a twisted way) about his younger sibling. The feeling isn't reciprocated.
- Blue-and-Orange Morality: Even by his family's standards, Illumi's morality is something else. Zeno, Silva, and Koko have all displayed varying degrees of being able to show empathy to others outside of their family. Illumi sees everyone as his puppets who need to be controlled for their own good, including family. This isn't because he likes controlling people, because he says it is out of familial love for them.
- The Comically Serious: You get the impression this is mainly why and how Hisoka manages to tolerate him for days at a time: you sometimes just need a dedicated straight-man to bounce mayhem off. That, and constantly trying to get those dead eyes to produce some reaction other than "pickled shark" could be seen as a hobby.
- Code Name: "Gittarackur" is what he calls his go-to disguise, such as the one he entered the Hunter Exam at the start of the series in.
- Dissonant Serenity: Despite being a Perpetual Frowner or because of it, he comes off as an even more brutal sadistic prick than Hisoka, which says a lot.
- Dragon with an Agenda: Ends up joining the Spiders, per Hisoka's request after the latter declared open war with them. While Illumi has associated with them in the past, he makes it known during his introduction that his only interest is killing Hisoka.
- The Dutiful Son: Followed his parents' footsteps and is a professional killer.
- Eerie Pale-Skinned Brunette: His sickly skin tone and dark hair make him all the more unnerving.
- Empty Eyes: Great, big, blackly blank pools of damn creepy that manage a permanent Thousand-Yard Stare.
- Expository Pronoun: Illumi uses the Japanese pronoun "Ore". In the Dark Continent arc, he uncharacteristically uses "Boku" instead, which happens to be Hisoka's pronoun of choice, hinting that he might be Hisoka in a disguise to get closer to the Troupe.
- Extreme Doormat: He might accuse Killua of being a puppet, but he'd do better looking in a mirror for that accusation to stick.
- Heterosexual Life-Partners: With Hisoka, during the exam. Even afterwards they're still shown hanging out together from time to time, though this friendship has its limits, such as Hisoka asking if it's okay to kill Killua. The resulting bloodlust from Illumi was strong enough to be felt from miles away. The relation changes, in some strange way, after Hisoka hired Illumi to kill him... and they're calling it an engagement.
- Knight Templar Big Brother: Extremely overprotective of Killua. He threatens to kill Gon since he's in the way of allowing Killua to become a full-fledged assassin. He is also responsible for putting a needle in Killua's brain to make sure he would avoid fighting stronger enemies at all costs to keep him safe.
- Laughing Mad: A terrifying case when he witnesses the immense power Alluka/Nanika has firsthand. He then becomes thoroughly convinced that he must have that power all for himself at any cost, declaring it belongs to him.
- Loophole Abuse: The Zoldyck's have a strict rule about not killing their own family which they must uphold. However, Alluka's bizarre existence and powers mean that the family considers them to be more of a dangerous creature under their care than one of the family, so Illumi sees no problem killing them. Killua is not amused.
- Master of Disguise: Using his pins and needles to change his appearance just for that extra squick value.
- Nightmare Face: When he gets angry, he goes from "creepy" to truly "nightmare-inducing". It's coupled with a killing intent so strong it's broadcast for miles.
- Not-So-Well-Intentioned Extremist: The entire plot of killing Alluka to prevent the wish blowback from wiping out his family or potentially many others initially sounds somewhat reasonable. However, this is entirely for selfish reasons rather than any sense of altruism, and not long thereafter quickly found to be antagonistic towards a better solution.
- People Puppets: One of the many uses of Illumi's needles is that he can control the minds and bodies of those pierced by them.
- The Quiet One: Creepily Quiet. When he does bother communicating, it's usually in a monotone others need to strain to follow.
- Soft-Spoken Sadist: Rarely raises his voice or shows emotion no matter what horror he is engaged in at the time.
- The Stoic: So much, that showing emotions makes him scarier than not showing them.
- Tough Love: What he thinks he's doing with Killua counts as this because he doesn't want his dear little brother to fight someone guaranteed to kill him. It's just a little needle driven into his head, and other mind-games to keep him further under control. It's for Killua's own good, you know. No one agrees with him, least of all Killua.
- Unholy Matrimony: Implied with Hisoka, after he contracted Illumi to kill him. If all his talk about engagement rings and prenuptial agreements is true, then this very well may be the case.
- The Voiceless: As Gittarackur, he never speaks. He is not this when he's around someone who knows his true identity.
- Yandere: Portrayed very much as a case of crazy love when Killua is concerned, albeit in a big-brother sense. He sincerely believes all of his measures where Killua is concerned are completely justified. Killua disagrees.

The second-oldest of Killua's brothers. He is an otaku and perhaps a hikikomori, keeping hundreds of anime figurines in his room. He has demonstrated no fighting skill of his own, but he has a genius intellect and creates death traps and doomsday devices with it. He normally stays within the family's estate, torturing his younger brothers as part of their assassin training. Milluki is directly responsible for Killua's total Acquired Poison Immunity and near total resistance to electric shock. He is proud of what he builds and will call his family members at random times to tell them about his latest inventions. He visits Yorknew City each year when the auctions arrive to try to buy Greed Island but has never been able to gather enough money to do it.
- Awesome, but Impractical: His inventions generally land here when he's left entirely to his own devices, including one that... blows up mosquitoes? However, when he gets it right, he hits Crazy Awesome. See Killua's yo-yos.
- Badass Bookworm: Not in the conventional sense, no. But, he can get the job done when you need him to kick a computer program or a whole network into submission quickly. He also has the standard family training, so good luck if you try to take him down with poisons or just hitting him with shocks. He can tank it.
- Big Beautiful Man: His sharp eyes and pouty lips give the impression that he'd be a bonafied Bishōnen if he lost weight.
- Butt-Monkey: His plans rarely go quite or fully according to plan. And, he's not as gifted in the conventional senses as his other siblings are. However, don't make the mistake of thinking that means he isn't dangerous. When he has to pull the stops out, he can work on many jobs in quick succession which mostly involve people winding up dead, for a lot of pocket money.
- Clint Squint: Does this practically on a full-time basis. Which helps hide the fact that, like Illumi, he also has the world's creepiest, blank eyes of black. Saved from hitting the Uncanny Valley so often chiefly thanks to the squint.
- Fat Bastard: He's fat. And, he's quite the Jerkass. In his defence, he's usually just going along with the flow. And the reason he's fat is because he's a shut-in glued to his computer who can't be bothered to exercise. It's cranked Up to Eleven when he tries to get his hands on a copy of Greed Island online and spends so much more time holed away indoors cramming miles of junk food into his system he goes from being fat to morbidly obese. But when he finally decides to actually leave the house, he burns off the excess calories... and at least manages to return to being his old overweight self.
- Gadgeteer Genius: Some of his more creative inventions are, admittedly, rather bad, but he is the one who made Killua's yo-yos. And, he can pull his weight on capers when he does go to work to produce more standardised things as needed.
- Hikikomori: After several years, he finally left the house for a while in the Yorkshin arc.
- Informed Ability: It's mentioned that he endured the Zoldyck training but he hasn't shown any of these abilities yet.
- Otaku: Very much — the computers, his figurines and his workbench are his life.
- Playful Hacker: What he is underneath it all, is someone who has fun messing around with computer programs instead of people. But, for his family's business, he'll be The Cracker as and when needed, too.
- The Resenter: Towards Killua. Milluki despises him for being their parents' favorite child and seemingly being a Karma Houdini despite constantly rebelling against their parents.
- Torture Technician: His specialty when he's not hiding behind a keyboard is torture. He's the one mainly responsible for Killua being accustomed to electric shocks. It was under Mother's orders, obviously.

The second youngest of Killua's siblings.
- Because You Were Nice to Me:
- Killua is the only family member who treats Alluka as family and a human being instead of a tool, a dangerous entity, or something to be controlled. Because of this, she's loving and affectionate to a fault around him, and it's almost stated outright that this is the reason some of Alluka's rules, like "Nobody may make two consecutive wishes", don't apply to him.
- Nanika has stated that she loves Killua as well, and for the same reasons; she is visibly hurt when he tries to send her away. As such, Killua's privileges regarding his wishes are not only dependent on Alluka's affections, but also of Nanika's well-being and permission.
- Creepy Child: Alluka can be a little too cheerful at times for full comfort, especially once you know what she can do... but, this isn't really the problem. When Nanika wakes up to play, things get creepy at light speed. She means well, but the mechanics of her ability...
- Early-Bird Cameo: She can be seen long before her proper introduction.
- She appears in siluoutte along with the other Zoldycks in the 2011 anime.
- Also appears in a family photo facing away from the camera.
- Four Is Death: All Zoldycks are assassins, but is it coincidence that the fourth child happens to have an ability (triggered upon refusal of four requests) to cause mass-murder? Even her parents are terrified of her.
- Magic A Is Magic A: Alluka's powers follow specific and reliable rules such as "one person must fulfill three requests before a wish can be granted", and "if one person refuses four requests then they die". Illumi refuses to negotiate with Killua during the Election Arc because Killua knows more rules than Illumi does, and so could leverage this hidden knowledge to his own advantage.
- Make a Wish: Alluka can grant wishes, and there doesn't appear to be a limit to the scale or nature of the wish, although there are some limitations as to how the wish manifests. When a butler wished to become a millionaire, Alluka redirected a plane carrying that much money over her family's mountain and forced it to drop its load.
- Troubling Unchildlike Behaviour: Is it normal for a child to seriously ask for your liver?.
- The Unfavorite: Apart from Killua, the Zoldycks don't even recognize Alluka as a member of the family, and Killua is the only one who loves her as a person. The family might have some cause for this negative attitude. If Nanika has "taken over" who Alluka would have been and the whole family (except for Killua) has been viewing the one we know as an imposter, it certainly would explain Kikyo's inability to fully accept "the imposter" as her child, including the lengths she's gone to to isolate it without killing it (if that's even possible).
- Killua himself isn't fond of Nanika for much of the "twins'" existence, but doesn't treat her as The Worst Thing Ever.
- Ambiguous Gender Identity: Alluka is referred to as a girl by Killua and dresses like a shrine maiden. However, the rest of the clan refers to Alluka as a boy or something non-gendered like "it" or "the entity" and, in a flashback, it's shown she wore more androgynous clothes as a little kid. Alluka also uses the female "I" pronoun of "atashi". Because of this, it's implied that Alluka is a trans girl.
- Big Brother Worship: Killua means the world to her. Even if he were the only person in the world to love her, she would still be happy and content.
- Black Sheep: In the eyes of her family she's a vicious creature that kills people according to Fair Folk style rules or petty reasons, instead of people she is contracted to kill for money, like them. The exception is Killua who considers her as the White Sheep, a sweet girl who wouldn't even harm anyone, let anyone kill, if others didn't exploit her power for selfish reasons.
- Born Winner: On the face of it, it looks like she developed her Hatsu both unconsciously and extremely early with little issue. Or not — extra material added in volume 33 of the manga confirms that Nanika is not a Hatsu and is, in fact, a fully individual Dark Continent being. Alluka presumably has not unlocked her own nen at all, possibly because of Nanika.
- Cheerful Child: The Alluka that Killua knows is always smiling and playful. Everybody else just finds her creepy.
- Outnumbered Sibling: Well, gender ambiguity aside and not to mention her younger brother's unhelpful cross-dressing tendencies, since Killua uses female pronouns for her and she also refers to herself as a girl, that would technically make her the only bone fide daughter of the family. Kalluto does complicate things, but he still refers to himself as male.
- Protectorate: Killua is fiercely protective of Alluka and protecting her from all threats, including his own family, becomes his drive from the Chairman arc onward.
- Spoiled Sweet: If Killua was spoiled then Alluka was absolutely spoiled, living in a large and colorful room with lots of toys and apparently no mandatory assassin training. She is also accustomed to her requests being granted promptly (because refusal has gruesome side-effects) but she is by far the kindest of the Zoldyck children and the requests she makes are controlled by Equivalent Exchange. As long as no one asks for something crazy like "a million dollars" then she only asks that others play with her.
- What the Hell, Hero?: Alluka gives Killua hell near the end of the Election arc when he tells Nanika to leave so that Alluka could have a normal life. She tells Killua that if he's going to love and protect her, then he has to do the same to Nanika as well and she won't forgive him if he doesn't. This gets through to Killua who apologizes to Nanika and promises to protect her too.
- Catchphrase: Whenever someone makes a wish, she will say "'Kay" to acknowledge it.
- Cuddle Bug: After Killua makes a wish to heal Tsubone's hand, and she does so, she immediately requests a hug from Killua.
- Cry Cute: She may be a mysterious entity, but you will feel sympathetic towards her when those creepy empty eye sockets of hers shift into a distressed scribble.
- Equivalent Exchange: In a twisted way. Any wish she grants does not require the one who made the wish to give something of equal value in return. Instead, it is the person who she pesters next who will be asked to pay for it. Failure to grant four requests results in the both pestered person and at least one of their loved ones dying. Depending on how great the at-gunpoint wish is, more people die — who dies also depends on how much time the pestered "client" has spent with those people, with the longest being higher on the dead list. However, the simplest way to circumvent the price and reset the whole thing? Wish for something both unselfish and positive for somebody or somebodies else. Or, just be Killua.
- Healing Magic Is the Hardest: Nanika can grant most wishes without a care for location but wishes to heal someone requires that she physically touch them.
- Jackass Genie: Though not, perhaps, by choice. And, it may actually be a subversion. As it turns out, Alluka/Nanika's twisted form of Equivalent Exchange only applies when granting cruel or greedy wishes. If they're asked to heal another on the asker's behalf or to do some other genuinely unselfish deed, Nanika just gets tired.
- Laser-Guided Karma: Nanika's wishes operate on some inscrutable "morality" system of sorts, where she continually pesters people for more and more severe requests. If they deny her, she will continue to pester other people until it reaches a peak at four, wherein she kills the fourth person via some unknown means. It's eventually revealed that this is due to the quality of the wish — asking for material goods, cruel acts, or selfish needs causes Nanika's pestering cycle, while asking her for a selfless or kind wish just tuckers her out. Though this still makes her dangerous, it does make her significantly less dangerous than initially assumed.
- Punny Name: Nanika translates to "something".
- Reality Warper: What that wish-granting ability of Nanika's basically amounts to. She doesn't seem to have any limits beyond the whole pester thing.
- Sharing a Body: Nanika is a distinct entity that inhabits Alluka's body and wakes when three "requests" are fulfilled or Killua calls on it. It loves Killua just as Alluka does, and the two are aware of each other's presence.
- Something Only They Would Say: If "Alluka" ever addresses Killua by his name then this means it is actually Nanika speaking, because Alluka only ever addresses him as "brother".
- Superpowered Evil Side: Averted. While Nanika's wishes can have nasty consequences, it's really not from deliberate malice, and she doesn't give any harmful requests if her previous wish wasn't greedy in nature.
- The Symbiote: The Dark Continent arc implies Nanika is a creature called "Ai" — one of them was shown saying Nanika's signature phrase. Nanika has since been confirmed as a DC being, but her being an "Ai" is still unconfirmed (but heavily implied). It is possible that a Zoldyck ancestor by the name of Zzigg who visited the Dark Continent with Netero may have brought a little something extra back with him.

Killua's youngest brother (yes that's a boy, he just likes to look like a girl), who is first seen following Kikyo around. He is later revealed to have joined the Phantom Troupe to search for his "missing" brother (most likely Killua, now that Alluka's been revealed to have been locked up in a glorified safe the whole time) and assists in the attack on the Chimera Ants infesting Meteor City. Though outwardly appearing calm and quiet, rarely speaking at length to others, he hides a bloodthirsty side and a deep commitment to his goal. Even while recognizing his massive inferiority to other members of the Phantom Troupe, he renews his determination to find his brother, no matter how long and how hard he has to work. He is a Nen user who fights with paper.
- Ax-Crazy: Mentions, looking completely innocent, that he needs to get over his bad habit... of playing with his prey. In the background of the panel is a Chimera Ant splattered all over the ground.
- Beauty Mark: Oddly enough, a quite fetching one. For a lad.
- Beware the Quiet Ones: Behind that calm and quiet exterior is a deadly assassin who can turn your body into minced meat by using confetti.
- Creepy Child: Well, yes. He is a young Zoldyck, so it's not like there was much other option. The pretty, porcelain doll thing he has going on is the icing on the cake.
- Death of a Thousand Cuts: His ability exploits this. His first onslaught is to first just fling a harmless flurry of confetti at the opponent. This has no chance of hurting the opponent, but if any of the confetti pieces does manage to embed into them, he'll follow it up with a powerful strike guaranteed to tear through the opponent. And if another piece of confetti gets stuck on the opponent after that, he'll do it again... and again and again until the opponent is totally torn to shreds.
- Dude Looks Like a Lady: Seriously — if you didn't know, you wouldn't guess. Dude rocks a frock like nobody else.
- The Friends Who Never Hang: Family-variant, though he spends most of his by his mother's side, he hasn't been seen interacting with the other members of his family. His most telling relationships are with his mother and Killua. In fact, the "Zoldyck Family Dynamic Chart" does not show any kind of relation to them.
- Impractically Fancy Outfit: Kimono. It would appear so but he can run quite quickly wearing it.
- Improbable Weapon User: Fights with paper of all things, and can slice through steel cable with a paper fan and dismember a Chimera Ant with flying streams of confetti.
- Informed Flaw: The "Zoldyck Family Dynamic Chart" states that Kalluto has a jealousy of Alluka, this fact hasn't been brought up in the story or explained. Especially since the two haven't been seen directly interacting with each other.
- Killer Rabbit: Looks like a young girl wearing a kimono. Is a member of a family of Professional Killers and the Phantom Troupe. He can also cut steel rope with paper.
- Mama's Boy: Heavily, heavily implied. He may be away from her for the moment, but only in the "went back to where she came from in the first place" sense, so it's hardly a case of breaking away.
- Overshadowed by Awesome: Him versus the other members of the Phantom Troupe. His normally calm expression turns to horror when he realizes that he can barely see Feitan's speed... while the other members comment that Feitan is rusty and not moving well. There are shades of this when it comes to the relationship between Killua and him as well. If the poor sod thought getting with the Phantom Troupe would help with that, he was most likely very sadly mistaken.
- Paper Master: Killer confetti? Why, yes: it's possible.
- Pint-Sized Powerhouse: If you think killing with paper is the most impressive trick he's got, you're going to be surprised about what else he can do, and how fast he can do it.
- The Stoic: He rarely displays any overt signs of emotion.
- Troubling Unchildlike Behaviour: He's a Zoldyck, so he's trained in assassin techniques, in addition to being fully versed in the use of Nen.

An apprentice butler who handles intruders on the estate.
- Badass Adorable: Face it, she's as cute as a button, and you know it. Can still whack with that baton of hers like nobody's business.
- Bad Liar: Or maybe it's because Gon is very observant.
- Battle Butler: The lowest one on the totem pole. But, if you think that means she's a pushover, you've just given Mike a free meal.
- Declaration of Protection: Towards Killua.
- Doppelgänger Spin: The Rhythm Echo, which leaves afterimages as you move.
- Emotionless Girl: Subverted. Her facial expression may be as neutral and calm as you'd expect from this trope the vast bulk of the time, but... there's actually a dynamo of feels living under it.
- I Lied: When she was starting out as a Zoldyck butler, she told Killua that she didn't know how to do the move Rhythm Echo. However, when a band of potential thieves came to rob the Zoldyck family house, she uses that very same move when she defeated the group all on her own. After Killua points it out, she admits that it was because she wanted to find some way to become friends with him.
- Improbable Weapon User: Fights with a rod.
- Like Brother and Sister: With Gotoh. She's also the most visibly concerned after his death.

- Posthumous Character: She doesn't make it past a flashback.

A Blacklist Hunter who works for the Zoldyck family.
The giant guard dog of the Zoldyck Estate.
- Canis Major: Looking like a cross between a wolf, a wolfhound and a werewolf. On growth hormones and a very expensive, and exclusive, protein diet.
- Cool Pet: Scary? Sure: but will do anything for a Zoldyck as long as he knows for sure they are one.
- Fluffy the Terrible: A cute, typical doggy name... slapped on that thing.
- The Heartless: Figuratively. Gon took one look in Mike's eyes and realized he couldn't make friends with him. Zebro even thinks he's more machine than beast.
- It Is Pronounced "Tro-PAY": In his case, it's pronounced "mee-keh".
- Nightmare Face: DEAR GOD. Try looking at his page image without getting the creeps. Gon himself was mortified by what he saw.
- Only the Worthy May Pass: There are two entrances to the Zoldyck property: The test door, which weighs several tons, or the maintenance door, which only requires a key to open. Problem is, Mike is ordered to kill and eat anyone he doesn't recognize that comes through the maintenance door.
- Stripped to the Bone: His Establishing Character Moment. Two thugs get suckered into taking the wrong entrance to the Zoldyck manor... we hear their agonizing screams... and then Mike pops open the door and reveals their barren, battered skeletons, having eaten everything meaty off them right down to their brains.
