Razor (レイザー Reizā?) is one of the Gamemasters and a creator of Greed Island. Razor was entrusted by Gon's father that he was not to hold back against his son should he ever comes to Greed Island. Razor is a key person in getting one of the hardest designated card of the game. To get the card, the challengers must confront Razor and his 14 devils in a group of 15 people, and defeat them in different sporting events. It is learned that the 14 devils were not his allies, but Razor's own ability to emit 14 Nen creatures at will. He is defeated in a dodgeball game by Gon's allied party (consisting of Gon, Killua, Biscuit, Hisoka, and several other hunter/players hired by Battera). Razor later reveals to Gon that he was formerly a convict captured by Ging and brought to the island as a prisoner. Inspired by Ging's spirit, Razor helped him create Greed Island and became the warden for the convicts. He also became one of Ging's friends and was entrusted to look after the island as one of its Gamemasters.
