Netero accepted, under the lighthearted condition that he would be brought some food first. The man broke down at Netero's feet, begging to be trained and offering the title of Grand Master in his stead. Among his audience was the grandmaster of the dojo, who was moved to tears by the raw power and grace brought about by Netero's training. His time on the mountain had allowed him the ability to strike faster than the speed of sound, to the astonishment and amazement of his onlookers. Sometime later, Netero descended from the mountain, returning to the dojo he had begun his training in and demonstrated his new strength. As a result, he spent the extra time in prayer, a development that led him to enlightenment.

Two years later, at the age of fifty, Netero had become capable of doing the ritual in under an hour. One day after that time had passed, he realized that although he had completed his ten thousand punches, the sun had not yet set. This would become Netero's daily routine for the next two years. After completing the ritual, he would collapse from exhaustion and fall into a deep sleep, only to awaken and repeat the ten thousand punches the next day. On the first day of his training, it took him over eighteen hours to complete ten thousand punches. During his time there, he showed his gratitude to the martial arts and would do a set of ten thousand punches and prayers daily.

Netero was trained in martial arts and, at the age of 46, he went to train in the mountains. At some point in his life, he fought Maha Zoldyck and became an acquaintance of the Zoldyck Family. His proficiency was such that it earned him the title of most powerful Nen user in the world. The circumstances in which Netero became a Hunter and learned Nen are unknown. Nonetheless, in certain occasions he prioritized results over sacrifices: he was willing to let as many as five million people die if that ensured the end of the Chimera Ant kingdom. He banned expeditions to the Dark Continent as a consequence of Hunters trying to imitate him and dying, and in spite of his fondness for challenges, he preferred to avoid fighting both Neferpitou and Meruem, hoping to end the conflict with the fewest casualties. His strength of mind and selflessness were beyond unwavering, and he did not hesitate to end his own life in a last attempt to kill Meruem.ĭespite his tendency to act as he pleased, Netero was not amoral. His goal in life was to find a worthy adversary against whom he could fight with his all. However, he was not arrogant, as he presented the possibility of Gon threatening him without saying the boy would stand no chance against him. He displayed a great deal of pride in his own abilities and had no respect for the weak. Netero had dedicated his life to the martial arts and prayer, intended as a form of appreciation. Additionally, he gave a quick glance at Menchi's cleavage during the 287th Hunter Exam. He apparently made a name for himself as a lustful man in the Hunter Association, since many Hunters left risqué magazines under his effigy as a tribute. He himself liked challenges, to the point he wanted his Vice-Chairman to be someone he just could not get along with. Biscuit Krueger even called Netero a "twisted individual", as he often enjoyed giving Hunters he trusted impossible assignments, sometimes with deadlines of only a few months, that should take years to complete. This strange passion affected the way in which he governed the Hunter Association, frequently testing the physical limits of those attempting to become Hunters. He enjoyed challenges, and was thrilled by the prospect of a formidable enemy. However, he was a true martial artist who was nothing but earnest during fights. There were clear discrepancies between his words and his thoughts during the 287 th Hunter Exam. Although he was capable of acting professionally when called to intervene as Chairman of the Hunter Association, on all other occasions, he proved himself to be so extravagant he was sometimes called insane. Netero was energetic, playful to the point of being mischievous, and, at times, seemingly absentminded. When in combat, Netero preferred to wear a t-shirt with the Japanese kanji character for the word "heart/mind", 「心」( kokoro), printed on the front and track shorts. During the Chimera Ant arc, he changed his appearance for his upcoming fight with Meruem by trimming his beard, mustache, and ponytail. Netero was commonly seen wearing a traditional man's kimono and pair of geta with one ha (tooth). He had a ponytail, a thick beard, and stretched earlobes with two piercings in both ears. Isaac Netero appeared to be a helpless old man, but was surprisingly fit and muscular for his age.
