Sergey Volkov (セルゲイ・ヴォルコフ, Serugei Vorukofu) is a character in the Yu-Gi-Oh! ARC-V anime. He became an infamous criminal known as the Dueling Destroyer (Duelist Crusher in the Japanese version) who was modified and became Jean-Michel Roget's primary enforcer in his military coup of New Domino City. At some point during his life (presumably after he was recruited by Roget), he received cybernetic implants and became a humanoid cyborg.
