Hunter x Hunter's nen system is an intricate power system that categorizes people's particular abilities! Most people stay in one nen type, and all their powers are derived from this type. This awesome list below, taken from the Hunter x Hunter wiki, first vocalized by Hisoka, describes more of each type!

Enhancers are simple and determined.[56] Most of them never lie, hide nothing, and are very straightforward in their actions or in their thinking. Their words and actions are often dominated by their feelings. They are generally very selfish and focused on their goals. This is reflected in their Nen as enhancers typically rely on simple and uncomplicated Hatsu techniques.

Transmuters are whimsical and prone to deceit/dishonesty. Transmutation users have unique attitudes, and many are regarded as weirdos or tricksters. Often they put forth a facade while hiding the truer aspects of their personalities. Even when they don't hide their personalities they rarely reveal their true intentions.[56] Many Transmuters rely on techniques that give unique and unpredictable properties to their Nen that reflects their personalities.
Emitters are impatient, not detail-oriented, and quick to react in a volatile manner. Many of them are quick-tempered and hot-blooded.[57] They resemble the Enhancers in building their impulsivity, but the difference between them is that Emitters probably tend to calm down and forget easier. Because of the nature of Emission, many Hatsu techniques created by emitters are primarily long range.

Conjurers are typically high-strung or overly serious, stoic, and nervous.[57] They are often on guard as to be cautious. They are very observant and logical, rarely falling into traps. Being able to analyze things calmly is the strength of Conjurers. Many of the items that conjurers create are often used by them in a very deliberate and practical, logical fashion.

Manipulators are argumentitive and logical. They advance at their own pace[57] and tend to want to keep their families and loved ones safe. On the other hand, when it comes to pursuing their own goals, they do not listen to what others might have to say about it. While manipulators often use techniques that allow them to control their opponents, some choose an inanimate medium to control.

Specialists are independent, individualistic, and charismatic.[57][58] They won't tell you anything important on them and will refrain from being close friends, but, because of their natural charisma that draws others, they are always surrounded by many people. Because Specialization is unique and can have many facets, most Specialists possess only one Hatsu technique.
