Bai Yun

Biodata

Power Progression

Bai Yun’s documented combat progression begins through his partner, Chimchar, and later expands into a six-Pokémon championship team centered on Fighting-type combat 15 387 713.

Background / History

Bai Yun grows up as the young heir of the wealthy Bai Group. Despite his family fortune, he does not want to manage the company. He chooses the Pokémon stream with the goal of becoming a Pokémon Breeder and achieving financial independence rather than being brought home to inherit the business 2.

He has known Cheng Tian since kindergarten and is identified as his best friend in both lives. Lin Lin also grows up with them. Bai Yun lives in a villa, and Cheng Tian visits often enough to have toiletries, sheets, and other belongings set aside there 2 4 23.

His father continues urging him to learn company management, but Bai Yun maintains that he is unsuited to running the business. The two families are already close enough for Lin Lin and her mother to visit his family during New Year’s Eve 132.

His initial breeding ambition eventually gives way to a more combat-focused path. At the Training Island camp, he becomes the Fighting-type Elite Four member’s apprentice, later identified as Shi Shen’s only disciple. He subsequently studies at Magic University and, after feeling increasingly left behind by Cheng Tian, commits himself to competing for Shi Shen’s vacated Elite Four seat 250 358 387 540.

Bai Yun takes time away from university to train at Mount Wudang, accompanied by Lin Lin. His later career culminates in a Pokémon League championship at age 24, although Cheng Tian ends his reign after two months 540 561 713.

Previous-Life Side Story

In the real-life side story, Bai Yun offers the narrator a salaried job in Bingzhou after hearing about his difficult working life in Capital City. He also agrees to help look after the narrator’s father, whose asthma and poor lungs remain a concern. Bai Yun reports that Lin Lin is working as someone’s manager in Magic City 47.

Personality

Bai Yun shares Cheng Tian’s unserious humor and enthusiasm for anime. He frequently teases his friend about girls, calls the back-row window seat the “protagonist’s seat,” and professes a preference for fictional “two-dimensional wives” over real-life romance 2 16 27.

His generosity is practical rather than merely verbal. When Cheng Tian prepares to enter the wilderness, Bai Yun offers to obtain a Pokémon through his father, supplies money and camping equipment, and helps conceal the preparations. He nevertheless objects strongly to the danger before reluctantly agreeing 3 4.

Bai Yun can be mischievous and self-protective: he provokes Lin Lin, tries to side with Cheng Tian’s mother when their deception is exposed, and copies homework after spending Sunday training Chimchar. As a Trainer, however, he accepts criticism and apologizes to Chimchar when poor commands cause a defeat 14 16 18 43.

His gentleness also extends to unfamiliar Pokémon. When a hungry stray Rockruff tries to take his food, he stops Chimchar from pursuing it and gives it the beggar’s chicken, explaining that life on the streets is difficult and that he can simply buy more 61.

His joking manner sometimes conceals strong emotional distress. After an illusion and nightmare in which Lin Lin disappears, he claims to have dreamed about anime characters instead, hiding his exhaustion and fear from his friends. The experience drives him to train particularly hard afterward 197 198.

Bai Yun develops an increasingly determined and competitive outlook without abandoning his humor. He accepts responsibility when his coach criticizes his reliance on purchased moves, is deeply moved by Rockruff’s perseverance, and promises to endure harder training alongside his Pokémon to protect what they cherish 167 222.

He describes himself as rebellious toward other people’s expectations. Although conscious that his wealth makes others view him as a carefree rich heir, he insists on attempting things others consider impossible. His concern about falling irretrievably behind Cheng Tian becomes a major reason for pursuing the Fighting-type Elite Four position 540.

His championship message reflects the emphasis on mental resilience developed during his training: “Stronger than the flesh is a heart that can never be defeated.” 713

Abilities & Skills

Pokémon Training

Bai Yun initially emphasizes mastering a few useful moves rather than accumulating skills without proficiency, although he later strays from this principle and has to relearn it under an Elite Four coach 19 167.

• Prioritizes Chimchar’s Thunder Punch and Fire Punch during entrance-exam preparations 19.
• Adopts weighted arm training after watching an instructional video with Cheng Tian; initially sets Chimchar’s load to five kilograms 19.
• By the battle assessment, Chimchar can deliver 140 punches per minute, each carrying 28 kilograms of force, with its weights removed 22.
• Purchases Bulk Up specifically to support Chimchar’s attempts to develop an anime-inspired technique 30.
• Later buys a large collection of TMs for Monferno and Rockruff, naming Thunder Fang, Fire Fang, Substitute, Protect, and Swords Dance among the intended additions 146 147.
• Acknowledges that he has focused too much on move variety after the Rock-type Elite Four member points out Rockruff’s ordinary execution and poor proficiency. Accepts Cheng Tian and Lin Lin’s offers to help him train 167.
• Learns fighting techniques from Shi Shen, whose continued coaching substantially improves Infernape’s close combat 222 338 342.
• After becoming Shi Shen’s disciple, favors Pokémon with the Fighting type while seeking variety through secondary typings rather than treating specialization as a reason to abandon coverage 387.
• At Mount Wudang, trains Lucario’s raw physical strength to the point that it can break a tree without using a move 623.

Battle Command

Bai Yun develops from a novice who over-directs his Pokémon into a Trainer capable of winning both placement-assessment battles 16 22 26.

• Opens against Elekid with Focus Energy and Work Up, then directs successive Fire Punch and Thunder Punch attacks 22.
• Learns from Cheng Tian that Pokémon should handle the flow of combat while Trainers give commands at crucial moments 16.
• His early reliance on forcing close combat leaves Chimchar vulnerable to Froakie’s ranged Bubble attacks 16.
• During the Jingxi Road mission, Chimchar’s offense works alongside Pachirisu’s Follow Me and Protect, but the level gap against Mightyena remains dangerous 48.
• Receives further criticism from Zhou Rongchang for ordering Chimchar into close combat with Exploud without withdrawing when the exchange becomes unfavorable 70.
• In the Rookie Tournament’s first team match, Chimchar draws Mienfoo’s attention while Qin Rourou’s Budew prepares and lands Solar Beam 83.
• Combines physical attacks with point-blank Flamethrower to keep Ambipom from retaliating during the Double Battle that leads to Chimchar’s evolution 89.
• Develops a three-team plan to separate Breloom and obtain Mushroom Powder during a Training Island mission, though the strength of the target and the arrival of a second Breloom complicate it 213.
• During the waterfall challenge, withholds Infernape after seeing the opponent’s Water-type attacks and sends Breloom to investigate because it is not weak to either Water or Fighting 624.
• Learns to examine an opponent’s training and temperament as well as its moves; Celestial Master Qingchen emphasizes that the waterfall Pokémon’s greatest advantage is its more tenacious heart 625.

Developed Techniques

Cheng Tian warns that Evil Fire Possession places a substantial psychological burden on Infernape. Bai Yun maintains that the state can be controlled as long as he does not push its anger too far 340.

Class Leadership

• Appointed temporary sports representative by Zhou Rongchang 29.
• Knows how to lead a group run and call cadence; leads the class through five laps of the school’s 400-meter track 29.

Physical Conditioning

Bai Yun initially dislikes exercise and struggles severely during the climb to his Mount Wudang training destination. Daily exercise and mountain training later transform his endurance and physique: Lin Lin notes that he has become tanned and developed abdominal muscles, and he can travel mountain trails without his earlier exhaustion 561 623.

Writing

• Has a longstanding interest in writing fiction and reports having written more than 300,000 Chinese characters before malicious reviews and speculative comments discouraged him from continuing 534.
• Recognizes the patience required to sustain a long work and encourages the new student Moufan after learning that his ongoing fanfiction exceeds one million Chinese characters 534.

Pokémon Partner

Chimchar

• Frequently shouts “muda” and imitates DIO-like mannerisms during training and combat 18 19 22.
• Bai Yun initially tries to change its viewing habits, then accepts its interest after seeing the resulting combat development 19 20 30.
• After their first recorded loss to Froakie, Bai Yun apologizes for his commands; Chimchar does not blame him 16.
• On evolving into Monferno, instinctively shakes off Bai Yun’s attempt to take its hand. The referee explains that Monferno’s hot temper can produce disobedience and advises further training 89.
• As Infernape, remains intensely eager to fight and repeatedly challenges Mount Wudang’s Mienshao, which can redirect its attacks and knock it unconscious 338 623.
• Battles alongside Lycanroc against Greninja and Ditto at university, but both are defeated by Greninja wielding the transformed Ditto as a katana 394.

Rockruff / Lycanroc

Bai Yun first encounters a filthy, hungry stray Rockruff during an outing with Lin Lin and gives it their beggar’s chicken instead of continuing to fight over the food. Rockruff watches them leave from an alley. A Rockruff is subsequently part of his active battling team 61 72.

• Battles alongside Qin Rourou’s Oddish in group training, losing after Aron defeats Oddish and Kakuna helps poison Rockruff 72.
• Learns a large number of moves, but initially lacks the training to use many of them proficiently. Demonstrates Earth Power and later ignores Bai Yun’s Stone Edge command while attacking uncontrollably 146 167.
• Uses Thrash during the Rock-type Elite Four member’s lesson, becomes confused afterward, and is safely knocked unconscious by Armaldo 167.
• Becomes increasingly aggressive before evolution, even briefly biting Bai Yun. This behavior is later explained as part of Rockruff’s pre-evolution period of challenging stronger opponents and tempering its will 222.
• Evolves into Midnight Form Lycanroc after repeatedly rising from injuries and exhaustion during a prolonged practical battle. Wins with Psychic Fangs, strengthening Bai Yun’s resolve to train alongside it 222.
• Defeats Yu Fei’s Snorlax shortly before Cheng Tian returns to Training Island 338.
• Is level 48 during the Mount Wudang waterfall challenge, where three rapid water-covered punches defeat it 624.
• Remains on Bai Yun’s championship team 713.

Cheng Tian remarks that the Bai family’s second child has not yet been born, establishing that Bai Yun also has a growing family by this point 736.
