Chairman of the Hunters Association. Known as the most powerful Nen user in the world. Seen in the anime/manga Hunter X Hunter.
Hardly anything is known about Netero's past. Somewhere in the past, when Netero was 46 years old, he was seen training in the mountains during winter time. He did 10,000 punches of gratitude to the martial arts that helped him mature, named Shingen-Ryu Kung Fu. After every single punch he would clap his hands together and pray. When he first started this it took him 5 to 6 seconds to complete the sequence and over 18 hours to complete the 10,000 punches and prayers. After he completed the sequence he would fall into a deep sleep and upon awakening he would resume the punching, day after day. After 2 years of following this daily routine he noticed a difference; when he finished the 10,000 punches the sun was still up. He continued doing this for another 2 years. At age 50 he managed to complete the 10,000 punches in under an hour. The time he spared by this he used to pray more. When he came down from his training in the mountains he could punch faster than the speed of sound. He demonstrated this at the dojo he had begun his training in, with the grandmaster of the dojo being moved to tears offering him the dojo and asking Netero to accept him as a student. Netero accepted this offer, under the condition that he would be brought some food first.
When Netero was in his mid-sixties, he sought challengers at his dojo which were determined to defeat him. Each challenger was defeated and showed their respect to him with a bow while Netero forgave them. Years later he would fight Maha Zoldyck, the grandfather of Zeno Zoldyck, from an elite assassin family and would be the only person to survive his encounter with the assassin. He also became the 12th chairman of the Hunter Association somewhere and was a member of the Serin Group, a team of versatile hunters which were so skilled they were considered legendary.
Enhanced physical strength: Netero has superhuman muscle strength despite his old age allowing him to char a wooden floor by simple force exerted from one single foot and perform inhuman feats like jumping several dozens of feet into the air and falling from great heights without sustaining any damage. His muscles when not completely relax have steel-like durability, as seen when Killua kicked Netero's leg and commented it was as hard as iron while that same kick would shatter a normal person's leg.
Enhanced reflexes: Due to Netero's long training in the mountains he has greatly increased his own speed. Netero can now punch faster than the speed of sound and can outspeed every single Chimera Ant including Neferpitou and Meruem. His fastest motion is his prayer motion, which he uses to initiate his special Nen Ability the 100-Type Guanyin Bodhisattva.
Enhanced pain tolerance: Netero has shown immense pain tolerance as even when his left arm and right leg were severed he didn't flinch.
Muscle control: Netero is able to control his muscles to a great extent, being able to harden his muscles to prepare for incoming impacts and prevent blood loss through sheer muscle control.
Martial artist master: Netero is the grandmaster of the Shingen-ryu kung-fu, a title which he gained after returning from his years long training in the mountains. He can deliver 10,000 punches in under an hour at faster than the speed of sounds. During his time as grandmaster he defeated every fighter that came to challenge the dojo, proving his skills in the Shingen-ryu kung-fu.
Nen: Netero has the ability to use Nen at very high levels having claimed the title of most powerful Nen user fifty years before the start of the series. He has an immense aura which people commented felt like being stung by needles. He has such control over his Nen abilities that his signature Nen Ability is a combination of Conjurer, Enhancement and Manipulation which he can use with great efficiency.
