Teppei Tairyōbata

Teppei Tairyobata (大漁旗 鉄平 Tairyōbata Teppei) is a character in the Yu-Gi-Oh! ARC-V anime. He is a participant in the Maiami Championship.

Personality
Teppei is rather arrogant, greedy, and lazy, having plotted to become allies with Michio, only for him to do all the hard work during the Battle Royale so Teppei could take away all his Pendulum Monsters after the latter was exhausted, and rejected Gongenzaka's challenge unless he bet 5 Pendulum Monsters knowing that he would be unable to do that. He likes taking credit and only acts when there's a worthy enough reward from him, as he didn't want to help Yūya when he was in Berserk Mode and tried to persuade Yūya into giving him Pendulum Monsters without dueling.

He can also be a coward at times, as he was reluctant to face the Obelisk Force and only accepted due to Michio's insistence. Despite seeing Michio as just a pawn at first, their friendship did become genuine, shown when Michio was brutally defeated and sealed into a card.

Battle Royal
He is a Fishing Duelist, and his favorite catchphrase is "Let’s catch a big haul of fish!". He has qualified to the Final 16 of the MCS, and takes part in the Battle Royale challenge.

Teppei went to the Jungle Area and hooked a Pendulum Monster to his fishing line, waiting for an unsuspecting Duelist to pick it up. Michio Mokota picked up the card and Teppei reeled it in, suggesting an alliance with him. He laid two more traps, catching Halil and Olga, and Michio Dueled them by himself. Teppei plotted to have Michio defeat the competition and then defeat him himself to assure his own place in the Top 8. As he was watching the Duel, Gongenzaka approached him and challenged him. However, Teppei refused Gongenzaka's bet off a single Pendulum Card and told him to come back when he could bet five, much to Gongenzaka's fury.

After Michio defeated Olga and Halil, Teppei brashly took their Pendulum Cards, much to the duo's disdain. Teppei was then roped into restraining a berserk Yūya Sakaki by Mieru Hōchun and helped hold him down, but was injured for his trouble. Losing his temper, he claimed that he wasn't Michio's friend, and Michio agreed, stating that he'd teamed up with Teppei to improve his skills. Yūya soon calmed down, and Teppei provided fish for their evening meal. He tried to swindle Yūya's Pendulum Cards out of him, but no one listened to him. Michio cooked breakfast for them the next day, and Teppei sincerely called him the best partner for both his cooking and Dueling skills. Yūya explained to Teppei and Michio about the Duelists who had invaded from another Dimension, and they split up to look for everyone else. Teppei and Michio found Mieru, who had run off beforehand, in the Iceberg Area and decided to get her to safety, much to Teppei's discomfort. However, they ended up running into the Obelisk Force, who were Dueling fellow competitors Shun Kurosaki and Tsukikage, as well as a girl resembling Yuzu Hīragi. Michio intervened, dragging Teppei with them, causing them to suffer the intrusion penalty of 2000 LP. Despite this, Teppei combined his "The Legendary Fisherman III" with Michio's "Royal Cookmates" to deal 2000 damage to each of their opponents. But their combo had inadvertently set up the Obelisk Force's own combo, which allowed them to revive their monsters with boosted ATK, inflict half of that ATK as damage, and then double that damage. Michio was defeated first and sealed into a card, much to Teppei's sincere shock, and Teppei was defeated next. In his final moments before being sealed himself, he dazedly wondered why Michio was a card, since they were supposed to be the strongest combination.
