Sergey Volkov

Sergey Volkov (セルゲイ・ボルコフ, Serugei Borukofu) is a character in the Yu-Gi-Oh! ARC-V anime. He works for Jean-Michel Roger. He is an infamous criminal known as The Duelist Crusher.

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 marks he has on his head, neck and upper torso. His left eye is capable of glowing red, implying it's technological in nature.

Etymology
Etymologically, Sergey's full name translates to "Protector of the Wolves." Given his connection to Jean-Michel Roger, his name references a Russian chess player of the same name.

History
Sergey was a dangerous Dueling criminal who viciously assaulted several Duelists, earning him the moniker of the Duelist Crusher. He was wanted dead or alive for these crimes. He was only stopped after a massive force of thirty 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 Gallager 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 Gallager and prompted the promotor to contact Jean-Michel Roger and send Sergey to him. Since then, Sergey served as Jean's agent.

Different Dimensions
Sergey was shown amongst the participants of the Friendship Cup. He later appeared standing behind Jean-Michel Roger, watching the tournament's matches.

When Selena was selected to Duel Tony Simons rather than him, Roger informed him that his Duel with Selena would be for later, since he had to beat the favorite Duelists in the tournament, then defeat Jack Atlas so as to shock the City.

He was eventually called to Duel Damon Lopez, shocking the audience 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 "Duelist Crusher". 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.
