Рілвельт

He's one of the three fighters that challenge Gon and Killua on the 200th floor of Heavens Arena. Having reached the 200th floor without the use of Nen, he was "initiated" after being attacked with a malicious aura attack and paralyzed from the waist down. He fights with his two whips, the Twin Snake (Thunder Snakes) which also have an electric shock built-in about 1,000,000 volts of electricity.
