As requested by @aspoonofsugar. 😀 

The Myers-Briggs Personality type is older than the Enneagram, and consists of sixteen types based on four different pairs of personality traits: Introversion vs. Extroversion; Sensing vs. Intuition, Feeling vs. Thinking, and Perceiving vs. Judging. To be clear, none of these categories are black and white–for example, all Feelers are capable of using logic, and Thinkers have feelings and care about people–but it’s a cool way of understanding personalities.

I’m not going to do every character, but simply the characters I think are most important and/or my favorites. 😛 Also, this is just my opinion and definitely open to debate! MBTI isn’t a science; it’s just a fun tool.

Main Characters:

Gon Freecss: ESFP “The Entertainer”

The biggest challenge ESFPs face is that they are often so focused on immediate pleasures that they neglect the duties and responsibilities that make those luxuries possible. Complex analysis, repetitive tasks, and matching statistics to real consequences are not easy activities for ESFPs. They’d rather rely on luck or opportunity, or simply ask for help from their extensive circle of friends. 

Killua Zoldyck: INTJ “The Architect” 

It’s lonely at the top… People with the INTJ personality type are imaginative yet decisive, ambitious yet private, amazingly curious, but they do not squander their energy.

Kurapika: ISFJ “The Defender” 

ISFJ personalities (especially Turbulent ones) are often meticulous to the point of perfectionism… ISFJs take their responsibilities personally, consistently going above and beyond, doing everything they can to exceed expectations and delight others, at work and at home. ISFJ personalities are a wonderful group, rarely sitting idle while a worthy cause remains unfinished

Leorio Paladiknight: ESFJ “The Consul”

Supportive and outgoing, ESFJs can always be spotted at a party – they’re the ones finding time to chat and laugh with everyone! But their devotion goes further than just breezing through because they have to. ESFJs truly enjoy hearing about their friends’ relationships and activities, remembering little details and always standing ready to talk things out with warmth and sensitivity.

Hisoka Morow: ENTP “The Debater” 

The ENTP personality type is the ultimate devil’s advocate, thriving on the process of shredding arguments and beliefs and letting the ribbons drift in the wind for all to see. Unlike their more determined Judging (J) counterparts, ENTPs don’t do this because they are trying to achieve some deeper purpose or strategic goal, but for the simple reason that it’s fun.

Illumi Zoldyck: ISTJ “The Logistician”

Their defining characteristics of integrity, practical logic and tireless dedication to duty make ISTJs a vital core to many families, as well as organizations that uphold traditions, rules and standards, such as law offices, regulatory bodies and military. People with the ISTJ personality type enjoy taking responsibility for their actions, and take pride in the work they do – when working towards a goal, ISTJs hold back none of their time and energy completing each relevant task with accuracy and patience..Dependency on others is often seen by ISTJs as a weakness, and their passion for duty, dependability and impeccable personal integrity forbid falling into such a trap… their blunt approach leaves others with the false impression that ISTJs are cold, or even robotic. People with this type may struggle to express emotion or affection outwardly, but the suggestion that they don’t feel, or worse have no personality at all, is deeply hurtful.

Chrollo Lucilfer: INTJ “The Architect”

He’s a confusing one because I kept going back and forth on the F or T function. But I lean T. 

While this may be intended as an insult by their peers, they more than likely identify with it and are even proud of it, greatly enjoying their broad and deep body of knowledge. INTJs enjoy sharing what they know as well, confident in their mastery of their chosen subjects, but owing to their Intuitive (N) and Judging (J) traits, they prefer to design and execute a brilliant plan within their field rather than share opinions on “uninteresting” distractions like gossip… A paradox to most observers, INTJs are able to live by glaring contradictions that nonetheless make perfect sense – at least from a purely rational perspective. For example, INTJs are simultaneously the most starry-eyed idealists and the bitterest of cynics, a seemingly impossible conflict. 

Dumpster Fire The Zoldyck Family

Alluka: ESFJ “The Consul”

ESFJs love to be of service, enjoying any role that allows them to participate in a meaningful way, so long as they know that they are valued and appreciated. 

Milluki Zoldyck: ISTP, “The Virtuoso”

While their mechanical tendencies can make them appear simple at a glance, ISTPs are actually quite enigmatic. Friendly but very private, calm but suddenly spontaneous, extremely curious but unable to stay focused on formal studies, ISTP personalities can be a challenge to predict, even by their friends and loved ones. ISTPs can seem very loyal and steady for a while, but they tend to build up a store of impulsive energy that explodes without warning, taking their interests in bold new directions.

Kalluto Zoldyck: ISFJ “The Defender”

I went back and forth on whether he was an ISTJ or ISFJ but decided on F thanks to that one brief snippet we had into Kalluto’s mind and how he desired to help Feitan whereas the other PT members did not. 

ISFJ personalities (especially Turbulent ones) are often meticulous to the point of perfectionism, and though they procrastinate, they can always be relied on to get the job done on time. 

The Phantom Troupe (or my faves there)

Machi: INTP “The Logician”

Further, with Thinking (T) as one of their governing traits, INTPs are unlikely to understand emotional complaints at all, and their friends won’t find a bedrock of emotional support in them. People with the INTP personality type would much rather make a series of logical suggestions for how to resolve the underlying issue, a perspective that is not always welcomed by their Feeling (F) companions… INTP personalities are so prone to reassessing their own thoughts and theories, worrying that they’ve missed some critical piece of the puzzle, that they can stagnate, lost in an intangible world where their thoughts are never truly applied.

Feitan: ISTJ “The Logistician”

ISTJ personalities are no-nonsense, and when they’ve made a decision, they will relay the facts necessary to achieve their goal, expecting others to grasp the situation immediately and take action. ISTJs have little tolerance for indecisiveness, but lose patience even more quickly if their chosen course is challenged with impractical theories, especially if they ignore key details – if challenges becomes time-consuming debates, ISTJs can become noticeably angry as deadlines tick nearer.

Phinks: ESTJ “The Executive”

ESTJs are aware of their surroundings and live in a world of clear, verifiable facts – the surety of their knowledge means that even against heavy resistance, they stick to their principles and push an unclouded vision of what is and is not acceptable… However, ESTJs don’t work alone, and they expect their reliability and work ethic to be reciprocated – people with this personality type meet their promises, and if partners or subordinates jeopardize them through incompetence or laziness, or worse still, dishonesty, they do not hesitate to show their wrath.

Pakunoda: ISFJ “The Defender”

ISFJs utilize excellent memories not to retain data and trivia, but to remember people, and details about their lives.

Shizuku: INTP “The Logician” 

Usually known as the philosopher, the architect, or the dreamy professor… They may appear to drift about in an unending daydream, but INTPs’ thought process is unceasing, and their minds buzz with ideas from the moment they wake up. This constant thinking can have the effect of making them look pensive and detached,

Uvogin: ESTP “The Entrepreneur” 

If ESTPs aren’t careful though, they may get too caught in the moment, take things too far, and run roughshod over more sensitive people, or forget to take care of their own health and safety… ESTPs are full of passion and energy, complemented by a rational, if sometimes distracted, mind. Inspiring, convincing and colorful, they are natural group leaders, pulling everyone along the path less traveled, bringing life and excitement everywhere they go. Putting these qualities to a constructive and rewarding end is ESTPs’ true challenge.

Shalnark: ENTP, “The Debater” 

ENTPs only make up about three percent of the population, which is just right, as it lets them create original ideas, then step back to let more numerous and fastidious personalities handle the logistics of implementation and maintenance.

Nobunaga: ESFP “The Entertainer” 

[T]here’s no greater joy for ESFP personalities than to bring everyone else along for the ride. ESFPs can chat for hours, sometimes about anything but the topic they meant to talk about, and share their loved ones’ emotions through good times and bad. 

Chimera Ants:

Meruem: ISTJ “The Logistician”

[P]eople with the ISTJ personality type often prefer to work alone, or at least have their authority clearly established by hierarchy, where they can set and achieve their goals without debate or worry over other’s reliability.ISTJs have sharp, fact-based minds, and prefer autonomy and self-sufficiency to reliance on someone or something.

Komugi: ISTP “The Virtuoso”

ISTPs love to explore with their hands and their eyes, touching and examining the world around them with cool rationalism and spirited curiosity… ISTPs explore ideas through creating, troubleshooting, trial and error and first-hand experience. … ISTPs enjoy lending a hand and sharing their experience, especially with the people they care about… ISTP personalities can be a challenge to predict, even by their friends and loved ones.

Pitou: ESFJ “The Consul”

ESFJs are the cheerleaders and the quarterbacks, setting the tone, taking the spotlight and leading their teams forward to victory and fame… ESFJs continue to enjoy supporting their friends and loved ones, organizing social gatherings and doing their best to make sure everyone is happy.

Shaiapouf: ISTJ “The Logistician”

People with the ISTJ personality type enjoy taking responsibility for their actions, and take pride in the work they do – when working towards a goal, ISTJs hold back none of their time and energy completing each relevant task with accuracy and patience… ISTJs tend to keep their opinions to themselves and let the facts do the talking, but it can be a long time before observable evidence tells the whole story.ISTJs need to remember to take care of themselves – their stubborn dedication to stability and efficiency can compromise those goals in the long term as others lean ever-harder on them, creating an emotional strain that can go unexpressed for years, only finally coming out after it’s too late to fix. If they can find coworkers and spouses who genuinely appreciate and complement their qualities, who enjoy the brightness, clarity and dependability that they offer, ISTJs will find that their stabilizing role is a tremendously satisfying one, knowing that they are part of a system that works.

Palm Siberia: ISFJ “The Defender”

ISFJs utilize excellent memories not to retain data and trivia, but to remember people, and details about their lives. 

Kurapika’s Side Character Buds

Senritsu/Melody: “The Advocate”

INFJs indeed share a unique combination of traits: though soft-spoken, they have very strong opinions and will fight tirelessly for an idea they believe in. They are decisive and strong-willed, but will rarely use that energy for personal gain – INFJs will act with creativity, imagination, conviction and sensitivity not to create advantage, but to create balance. Egalitarianism and karma are very attractive ideas to INFJs, and they tend to believe that nothing would help the world so much as using love and compassion to soften the hearts of tyrants.

Oito Hui Guo Rou: ESFJ “The Consul”

Moral of this: Why Oito should take over the Kakin Empire and make it a matriarchy. 

ESFJs are more concerned with fashion and their appearance, their social status and the standings of other people. Practical matters and gossip are their bread and butter, but ESFJs do their best to use their powers for good. ESFJs are altruists, and they take seriously their responsibility to help and to do the right thing.
