Sergey Volkov 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 . Design . Appearance . Sergey is a very tall and muscular individual , towering above most other characters . He wears a full - body riding suit with green and purple parts , which are separated by a red lines . There are spikes on the elbows , around his middle and on bracelets . The suits opening is very broad , exposing a lot of skin from his upper torso , showing the many criminal mark s he has on his head , neck and upper torso . His left eye is technological in nature , being a high tech scanner which can also provide Roget with a live feed of Sergey ' s view . His right sleeve was torn open during his Duel with Zuzu Boyle and his arm was scarred , but his left arm appears to be completely mechanical and contains his Duel Disk , in a similar manner to Rex Goodwin . His legs were later shown to contain booster rockets , allowing him to accelerate explosively and fly . When merged with his Duel Runner , he comes out on top of the converted machine , riding single - wheeled with the former front wheels acting like extendable arms . Towards the end of his life , his identity as an actual humanoid cyborg is shown , as he consists of metals , wires , machinery , and scraps covered up with a humanoid appearance . Personality . Sergey is a Duelist who Duels in a cruel manner , similar to Yami Marik and Kalin Kessler . He continually inflicts damage to himself without attempting to stop it in addition to reveling in his own pain . He revels in the suffering he causes towards his opponent , as seen in his Duel against Zuzu where he brutally defeated her and rammed her Duel Runner with his own and went to describe the carnage as " beautiful " . He enjoys giving his opponent a false hope of victory and then crushing them , being submissive for most of the Duel , then defeat them with overwhelming power . However , these personality traits are usually restrained by Roget through the use of a mind - control device . When Sergey gets highly excited or surprised by illogical Dueling behavior however , the mind control breaks partially , revealing his own hot - blooded nature , expressing his love for " beautiful " duels . This obsessive desire is worth everything to him , refusing rescue from a fatal fall so as not to ruin the moment . His idea of beauty , however , still remains as the process of destruction . Abilities . Sergey ' s abilities are all primarily products of his cybernetic body , which Jean - Michel Roget describes as the " ultimate living Duel machine " . He has incredible strength ; he is able to effortlessly break through a solid wall with little acceleration and easily beat down multiple individuals with hand - to - hand combat training . He can produce his Duel Disk directly from his cybernetic left arm , and he can boost across the ground at high speeds and fly with the rocket boosters built into his legs . Like the Three Pure Nobles and their true form , he can merge with his Duel Runner , although , unlike them , his body does not undergo any visible transformation . Due to his enhanced left eye , he can also scan cards on the field or ahead of him to further his strategies . There seems however to be some degree of side - effects to his cybernization . The most recurrent of them is a visible mental instability which tends to trigger when he becomes excessively excited , causing him to lose restraint and Roget losing partial or total control over him , unless captured and submitted again . His left eye which is also connected to an internal computer seems to be sensitive to information , as an apparently illogical play during a Duel was enough to trigger an error display and briefly disable his attention . Etymology . Etymologically , Sergey ' s full name translates to " Protector of the Wolves . " Given his connection to Jean - Michel Roget , his name references a Russian chess player . Voice / Mannerisms . In the dub , Sergey speaks with a Russian accent and in slightly broken English . He also tends to use computer terminology when Dueling such as ' protocol ' , ' initiate ' , and ' compute ' . In the original , while he is under the control of Roget , Sergey speaks in a monotone until he breaks free . Biography . History . Sergey was a dangerous Dueling criminal who viciously assaulted several Duelists , earning him the moniker of Dueling Destroyer . He was wanted dead or alive for these crimes . He was only stopped after a massive force of thirty Sector Security operatives managed to capture him . He was sent to the Facility as a result . However , even in the Facility , Sergey was just as brutal as in the outside , and single - handedly defeated all the other inmates in the prison . His viciousness was such that he had to be placed underground . While in the underground , he was met and welcomed by Lucas Swank who explained the rules of the disposal center and how he could climb back to the surface if he defeated every Duelist around . Sergey did so , destroying fifty opponents by himself , a feat that shocked Lucas and prompted the promoter to contact Jean - Michel Roget and send Sergey to him . At some point , Roget had Sergey undergo mind - altering surgery and had had his body modified to be largely technological in nature , turning him into his agent . Friendship Cup . Sergey was shown amongst the participants of the Friendship Cup . He later appeared standing behind Roget , watching the tournament ' s matches . When Celina was selected to Duel Tony Zomboni rather than him , Roget informed him that his Duel with Celina would be for later , since he had to beat the favorite Duelists in the tournament , then defeat Jack Atlas so as to shock New Domino City . He was eventually called to Duel Damon Lopez , and the audience were shocked to learn that he was the legendary criminal . The Duel started and the young Commons resident seemingly dominated Sergey for most of the match , constantly forcing him on the defensive , leaving the audience and Damon unimpressed with the " Dueling Destroyer " . However , through unknown means , Sergey reverted the situation in one fell swoop and instantly defeated Damon , destroying his Duel Runner and leaving him injured , stunning the entire audience as to how exactly he had won . Friendship Cup Finals . In the second round , he was set to Duel Zuzu Boyle , and ordered to bring her to Roget as she was one of the pieces that he required to build his kingdom . The news caused Sergey to smile . He Dueled Zuzu as the first match in the second round of the Friendship Cup , and appeared to be at a disadvantage for most of the Duel despite the strong effects of his " Thorn Prisoner " monsters . Sergey set up Thorn Counter s that continually damaged him , and a fragment of pavement tore open his sleeve and scarred his arm , causing him to call it beautiful . He was amused when Zuzu displayed concern for him and believed that she had the Duel won after reducing his LP , and called it beautiful , far better than his Duel with Damon . Breaking from the control of his limiter , he Fusion Summon ed " Thorn Overserver Vandarlizuma " on his next turn and madly declared that he had endured the pain until he got what he wanted . " Van Darli Zuma " defeated Zuzu ' s " Bloom Prima the Melodious Choir " and when Zuzu attempted to get an Action Card , he crashed his Duel Runner into hers , flinging her through a building . He returned to the Duel Palace in a giggling daze , and didn ' t seem to register Sector Security taking him into custody . Sergey was sent to his doctor so that he could begin " reprogramming " him . Roget later insisted that the doctor hurry the process along so that the same could be done to Yuya Sakaki . After his " reprogramming " , Roget sent him to the Council Building to help recapture the High Council . While waiting , Roget had Sergey intercept the Obelisk Force instead after they started to invade New Domino City . Sergey engaged the Obelisk Force outside the Capital Building and continually defeated their members . Roget then sent Sergey to retrieve Zuzu and Celina from both the Lancers and Duel Academy forces . Sergey joined Yuya and Barrett ' s Duel , taking the intrusion penalty , then trapping Zuzu with his Field Spell " Earthbound Prison " . He simultaneously Fusion and Synchro Summon ed " Earthbound Servant Geo Gryphon " and " Earthbound Servant Geo Kraken " and finished off Barrett in an OTK . He was however , unable to stop Barrett from carrying Celina back to the Fusion Dimension at the last moment . An enraged Roget instructed Sergey to ensure Zuzu ' s capture . Although Yuya , now free of Barrett ' s " Chains " , Summoned " Odd - Eyes Rebellion Dragon " , Sergey destroyed it with " Geo Griffon " and then defeated the defenseless Yuya . Knocking down Moon Shadow , " Twilight Ninja Shingetsu " and Sora with his rocket boosters , he grabbed Zuzu , broke through the ceiling and flew off with Zuzu , successful in his mission . The next day Sergey Dueled against Jack Atlas for the second semi - final , who accepted the challenge due to Yugo ' s absence . During the Duel Sergey used the effects of his " Earthbound " cards to Synchro and Fusion Summon simultaneously . He tried to destroy Jack ' s " Scarlight Red Dragon Archfiend " , but Jack managed to protect his ace monster and destroy both of Sergey ' s " Earthbound Servants " . After using " Earthbound Tundra " to deal burn damage to Jack , Sergey ' s program started to drive him mad and combined him with own Duel Runner to become the ultimate Duel Machine . As the Duel intensified , Sergey ' s heartbeat rose . He attempted to slow Jack down by tearing up the track with his Runner ' s arms , and Synchro and Fusion Summoned " Earthbound Servant Geo Gremlin " and " Earthbound Servant Geo Gremlina " , then he forced Jack to choose whether to destroy " Scarlight Red Dragon Archfiend " . Jack refused to destroy the pride of his soul and kept his ace monster out and continued to protect it . When Sergey began to fall off the track due to the damage that he ' d caused to the track destroying the bridge , Jack saved him from falling using " Scarlight " . This corrupted Sergey ' s program and unleashed Sergey ' s sadomasochistic nature , breaking himself from the control of Roget . It finally came down to them no longer using Action Cards , and despite Sergey summoning his ultimate " Earthbound " , " Earthbound Servant Geo Grasha " , Jack was still able to hold on and win the Duel . When Sergey was thrown off the course , Jack attempted to save him once more , but Sergey rejected it this time , knocking away " Scarlight " with one of the arms of the Duel Machine . He requested that Jack honor his beautiful defeat before falling to his presumed doom . Despite being heavily damaged from his fall , Sergey survived and attempted to crawl away . Here , it is revealed the extent of Sergey ' s cybernetic modifications : the skin on his face and shoulders peeling away to reveal a metallic skull and musculature , while a crackling mess of broken machinery and wires spilled out bloodlessly from his torso and lower body . However , a group of nearby Commons saw him , recognized him as the Duelist Crusher , and proceeded to pick up weapons . A moment later , his vitals monitor in Roget ' s office defaulted to a " NO SIGNAL " message , implying that Sergey was killed . Decks . Thorn Prisoner . Sergey initially runs a " Thorn Prisoner " Deck . His Deck focuses on the reduction of his own LP at a calculated rate through the effects of his monsters and through Thorn Counter s . To facilitate this , his monsters all have 0 ATK and DEF . Sergey can use both Synchro Summon ing and Fusion Summon ing to bring out his key monsters to capitalize on his low LP and inflict large amounts of damage . Earthbound . Sergey later switches to an " Earthbound " Deck that he debuts in his Duel with Barrett and Yuya Sakaki . Like his previous Deck , it focuses on Fusion and Synchro Summon ing . The main strategy of this Deck is to simultaneously Summon Fusion and Synchro Monster s , by using the same materials for both Summons with the effect of " Harmonic Synchro Fusion " . Some of his cards also gain effects when the Field Zone is occupied .
