Nen is the ability to manipulate life energy (aura). Mastery involves four fundamentals - Ten, Zetsu, Ren, and Hatsu - with Hatsu expressing a user's unique combat style. Each Hunter's Hatsu is guided by their Nen type.

The Six Nen Types

• Enhancer: Reinforces self or objects to boost raw power.
• Emitter: Projects aura at range with control and speed.
• Manipulator: Controls targets — objects or even people.
• Transmuter: Alters aura’s properties to mimic something else.
• Conjurer: Materializes constructs with specific rules and conditions.
• Specialist: Unique abilities outside the standard categories.

Training demands discipline, creativity, and risk. Oaths and limitations can amplify power in exchange for strict conditions - a core theme across Hunter x Hunter’s strongest abilities.
