Yūgo

Yūgo (ユーゴ) is a character in the Yu-Gi-Oh! ARC-V anime. He is the Synchro Dimension counterpart to Yūya Sakaki (from the Standard Dimension), Yūto (from the Xyz Dimension), and Yūri (from the Fusion Dimension).

Appearance
Similarly to his dimensional counterparts, Yūgo has dual hair color. The front bangs of his hair are blonde and the base hair that sits on his head is blue. He wears a white jacket with red borders and yellow stripes on the sleeves, along with a white jumpsuit that has red, blue, and yellow stripes that meet in the center in a chevron pattern, white gloves, shoulder, elbow and knee pads, and gray boots.

Personality
Yūgo is shown to be very impulsive and short tempered, especially when his name is pronounced incorrectly. Because of this, Yūgo frequently got into many fights against others, including Yūto, who incorrectly stated he was a pawn of Fusion, and the Ryozanpaku School Duelists who mistook him for Yūya Sakaki.

He also appears to be extremely unaware of his surroundings, as he failed to notice Yuya at all during his Duel against Yūto, despite Yūya talking to him constantly throughout the Duel, and on both trips to the Standard Dimension he showed almost no awareness of where he was or how he got there. Yūgo also appears to be extremely protective of a girl named Rin who upon mistaking Yuzu Hīragi for her hugged her and smiled.

Etymology
His name, Yūgo (ユーゴ) is often confused with Yūgō (, Fusion), causing most people (mainly the Resistance) to mistake him for a "Pawn of Fusion".

Past
While growing up, Yūgo and Rin were raised as orphans in the slums of City as commons. Inspired by Jack Atlas, he and Rin perfected their Dueling skills to compete in the Friendship Cup to challenge Jack to a Turbo Duel. Together, they built a Duel Runner to achieve their dream.

A few years later, Rin was being targeted by Yūri as per the Professor's orders, and Yūgo rode around looking for her. However, when he found her, Yūri had already defeated Rin and disappeared. Shortly afterwards, "Clear Wing Synchro Dragon" shined and teleported Yūgo to Heartland City in the Xyz Dimension. There, Yūgo searched for Rin and but instead spotted Yūto. Yūto accused Yūgo of being a member from Academia, and Yūgo challenged him to a Duel in response. Yūto brought out "Dark Rebellion Xyz Dragon" and Yūgo grout out "Clear Wing Synchro Dragon" but fled when Shun Kurosaki and other members of the Resistance came to Yūto's aid.

Round 1
Yūgo arrived in the Standard Dimension via Clear Wing Synchro Dragon. He crashed into a pole and started complaining about it until Yūto noticed him. The two then started a Duel with Yūya Sakaki watching. He battled with his Duel Runner and brought out his ace and permitted Yūto to do the same so that they could "settle the score". However, they then went berserk, and Yūto gained the upper hand and began to obliterate "Clear Wing Synchro Dragon". However, Yūya stopped him and helped Yūto break out of berserk mode. Yūya couldn't snap Yūgo out of berserk mode, however, and Yūgo proceeded to defeat Yūto. After the Duel, Yūgo returned to his normal state of mind, unaware of being possessed. He was transported away by a bright light afterwards.

Battle Royale
Yūgo returned to the Standard Dimension by the same mean of transport during the Maiami Championship Junior Youth Battle Royal. He arrived in the Iceberg Area, mistaking it as an apocalyptic future. He spied Ken Umesugi and Makoto Takeda of the Ryozanpaku School. They mistook him for Yūya, prompting Yūgo to indignantly declare that his name is "Yūgo". Yūgo quickly defeated them in a Duel and yelled out to see if there were any other people nearby.

Yūgo went to the Volcano Area where he spied the Obelisk Force turning the Lancers into cards. With only Yū Sakuragi left standing, Yūgo joined the battle and quickly brought out his ace and used its Special Ability to defeat the Obelisk Force. He later returned to the Iceberg Area, where he spied Yuzu Hīragi. Mistaking her for Rin, Yūgo leapt off his Duel Runner and hugged her. As Yūya came in close proximity, Yuzu's bracelet shone and teleported her and Yūgo away.

Synchro Arc
Yuzu's bracelet transported her and Yugo back to the Synchro Dimension, Yūgo's homeland. Concerned for Yuzu's safety, he tried to wake her up, and was unprepared for her startled response to him being close to her, resulting in Yuzu pushing Yūgo into his Duel Runner. After checking up on his Duel Runner, he warned Yuzu to be careful around it, and when prompted, explained that they were in the City, his hometown. He was pleased when Yuzu got his name right and then angered when she asked if he was allied with the Fusion Dimension, realizing that she wasn't Rin, since Rin wouldn't have gotten his name wrong. Yuzu mentioned a Duelist who had kidnapped Rin, much to Yūgo's interest. He asked where the Duelist was now, but Yuzu admitted that she didn't know and explained that he'd vanished when Yūgo showed up.

Yūgo explained to Yuzu that she was in the Synchro Dimension, and reassured her that he'd been surprised the first time he'd crossed dimensions as well, which had been after Rin was kidnapped, upon which he'd found himself in the Xyz Dimension's Heartland. Yuzu informed Yūgo that Yūto hadn't been the person that had kidnapped Rin, and that he was in fact trying to find someone precious to him as well, like Rin was to Yūgo. Yūgo was quite surprised, and he denied, blushing, that Rin was his girlfriend when Yuzu asked him about it. Yūgo explained to Yuzu that "Clear Wing Synchro Dragon" had transported him across dimensions, and they realized that the Duelist that had kidnapped Rin must have been nearby the first time he Dueled Yūto. Yuzu explained about her and Yūgo's dimensional counterparts, suggesting that those with the same face may be drawn to one another, and Yūgo remembered in shock that the Duelist that had been with Yūto had had the same face as him. Yuzu explained about the four dimensions, as well as the goals of Academia and the Professor. Pleased that he knew where Rin was, Yūgo suggested that they storm Academia using Yuzu's bracelet, but Yuzu explained that it only worked when Yūya was around and broke down in tears. Yūgo apologized, handed Yuzu a handkerchief and admitted that he couldn't control "Clear Wing Synchro Dragon" either, and that he needed Rin to keep him in line.

They were interrupted when the Tops finally noticed them, and they fled on Yūgo's Runner. Yūgo explained the competitive society of the City to Yuzu, as well as the history of the Duel King, Jack Atlas, whom he and Rin had idolized and built their Duel Runner for the purpose of Turbo Dueling. A Security member arrived, and Yūgo attempted to outpace him, explaining that their trespass would mean being sent to a Facility if they were caught. The Duel Chaser forced a Turbo Duel, and Yūgo asked for Yuzu's name, since he hadn't before. Telling her to hold on tight, he began the Turbo Duel.

Trivia

 * Unlike his dimensional counterparts, Yūgo is the only one who doesn't wear a cape (or any clothes that make it look like one).
