Background / History

Sui Yan is Lu Ze's childhood friend. When Lu Ze moved to Chang'an City as a child, Sui Yan cried and insisted on accompanying him; Sui Yan's father subsequently transferred jobs so the two could remain together. Their relationship is close enough that they refer to one another as brothers, despite their constant teasing and competitive bickering. 12

During the Academy Battle Tournament, Sui Yan qualified for the Main Event through ten consecutive victories. He initially relied on Growlithe, displaying effective tactical command even against unfavorable matchups, before Growlithe later evolved into Arcanine. 34 35 36 107

As his strength grew, Sui Yan developed from a straightforward Fire-type trainer into a specialist in Sunny Teams and flexible weather-based compositions. He entered major domestic and international competitions alongside Lu Ze and Tang Yunqin, eventually becoming one of Dragon Nation's strongest young Trainers. 609 710 882

At the World Youth Championship, Sui Yan formed a major rivalry with Ambrose of the United States. Their Reshiram and Zekrom repeatedly clashed; although Sui Yan's initial individual match was disrupted by Kyogre's sudden rain, he later defeated Ambrose and Zekrom in the team competition. 809 833 1222

Sui Yan later rose through the World Elite Four Rankings, defeating ranked Trainers such as Samon Hernandez and Chu Wanquan. He also traveled with Lu Ze into the Pokémon world, where Professor Oak arranged an identity for him and he began competing against Trainers such as Korrina and Iris. 1387 1390 1476 1477 1509

Personality

Sui Yan is outgoing, loud, and highly competitive. He frequently boasts before battles, calls attention to his own “heroic performance,” and refuses to back down when provoked—even when he is visibly nervous about a challenge. 34 443 750

His confidence is balanced by loyalty and self-awareness. He readily follows Lu Ze into dangerous situations, seeks Lu Ze's advice after defeats, and recognizes that his own tactical ability improves through studying stronger Trainers. 110 629 892

Sui Yan can also be impulsive. He bought an overpriced map of the Black Secret Realm without comparing it to maps his group already possessed, and he has a history of making purchases based on enthusiasm rather than preparation. 326

Despite his bravado, he has a softer side. He wants a small Fire-type Pokémon he can carry in his arms, is protective of his friends, and is easily pleased by praise from his girlfriend Wu Mengxin. 666 1135

Abilities & Skills

Sunny Team Strategy

Sui Yan is a weather-team specialist whose primary strategy centers on establishing and exploiting Sunny Day.

• Reworked his Sunny Team to include Pokémon outside a purely Fire-type composition, favoring individual strengths over rigid team construction. 882 1378
• Can dismantle his standard weather composition when necessary and adapt to an opponent's team rather than forcing the same plan. 1378
