Isaac Netero

Netero (ネテロ Netero) is the Chairman of the Selection Committee for the Hunter Exam. Presiding over it, Netero has final authority over every stage of the examination. In his first appearance he makes a 60-foot free-fall jump from the Judging Committee's blimp without a parachute, landing square on his feet without any sign of damage.

He was said to be the strongest Nen user in the world 50-years prior to the start of the series. In his youth, Netero spent four years doing ten-thousand punches and praying every day in order to express gratitude to the martial arts. His time spent doing those punches and prayers led to his enlightenment, giving him the ability to punch faster than the speed of sound. Netero is the Grand Master of the Shingen-Ryu style of Kung fu.

Netero is also revealed to be older than Zeno Zoldyck, who is said to be 67 years of age. At one point, Zeno says that when he was still a young boy, Netero was not only already old, but he is the only person alive who has fought with Maha Zoldyck. Various stated times would put Netero over the three digit mark.

Combat
Netero's ability, the 100-Type Guanyin Bodhisattva, utilizes Nen to make his attacks seem as if they had come from another dimension due to their incredible speed. When activated, Netero conjures a gigantic multi-armed statue of Guanyin using his aura. The arms on the statue strike down upon their targets in conjunction with Netero's own hand motions.
