Nistro

Gauche is a character appearing in the Yu-Gi-Oh! ZEXAL anime. He is Dr. Faker's right-hand man and a committee member responsible for maintaining the World Duel Carnival. He works together with Droite for Mr. Heartland along with Kaito Tenjo.

He has a Duel Disk which looks a lot like IV's. He also has a d.gazer tatoo, like Kaito Tenjo, III, IV and his partner Droite.

Personality
Opposite to Droite's cold-blooded personality, Gauche is a very high-spirited person evident to how excited he got during the opening ceremonies of the World Duel Carnival. He also seems to take his job less seriously as when investigating mysterious duels within the tournament, he joked about how some of the duelists were defeated whilst Droite maintained a calm manner whilst investigating.

Biography
During the opening ceremonies of the World Duel Carnival, Gauche along with Droite and Mr. Heartland kept watch over various parts of Heartland. Seeing the amount of duelists excited Gauche, but he was quickly scolded by Droite who told him to be more professional. He then argues with Droite but is stopped by Mr. Heartland. Then Kaito arrives due to Mr. Heartland requesting him to which Gauche joked about Kaito and how he came so quickly to which Kaito gave Gauche a dirty look.

Deck
According to the December issue of the V Jump magazine, Gauche along with Droite plays a Photon Deck much like Kaito Tenjo who also works for Dr. Faker.

Trivia

 * "Gauche" means "left" in French. This may be a reference to the fact of him being Dr. Faker's "left hand" while Droite is the "right hand".
 * Although Gauche has a normal D-Gazer, in episode 37 he is seen dueling with a tattoo-like D-Gazer like the ones used by Tron's family and by Kaito.
