Physical Description

Jiang Yun presents a strikingly handsome and youthful figure, often described as a "monster-like man" in terms of his good looks, with an appearance that immediately commands attention 24. He appears to be in his late teens to early twenties, with a slender, agile build that is not particularly robust but exudes a sense of latent power and grace 8. His demeanor is marked by an ethereal temperament and an unfathomable stillness, making him seem both exceptionally young and mysteriously wise beyond his years 38 44. When not actively concealing his presence, he gives off a plain and unremarkable impression to casual observers, yet those with keen perception sense a profound depth and harmony with the world 20 31. His movements are unhurried and steady, and his expression often carries a carefree, unrestrained air, especially when adopting a persona of a wealthy young master 31 40.

• Age and Build: Appears to be seventeen or eighteen years old, with a lean, slender physique that is not muscularly robust but capable of explosive power 8.
• Facial Features: Described as handsome, with traits that align with Earth's aesthetic ideals; mentioned as having a "slender waist and long legs" only in reference to another character (Tights), but his own attractiveness is consistently noted 4 24.
• Aura and Presence: Possesses an ethereal, almost otherworldly temperament that makes him seem shrouded in mystery; when calm, he blends into his surroundings, yet his aura can become sharp and intense during combat 20 44.
• Expression and Demeanor: Often wears a friendly smile or a carefree, unrestrained expression; his eyes are described as profound and ambitious, reflecting his inner drive 31 38 40.
• Attire: Typically seen in simple martial arts clothing; later adopts a custom red-and-white combat uniform for the Blazing Squad, designed to be both striking and formidable 40.

Background

Jiang Yun originated from Blue Star, a world he left behind after death or transport—the exact circumstances of his arrival in the Dragon Ball universe are not recorded. He found himself as a twelve-year-old boy in a world of talking animals, flying cars, and hidden martial arts masters, and he was ecstatic. In his previous life, he had been the CEO of a listed company whose greatest passion outside of money was martial arts; now he had a second chance to pursue that passion in a realm where ki was real and power could transcend the limits of the human body 1. Over the next three years, he trained relentlessly. Although his body's potential rivaled that of Krillin—the strongest Earthling in the original timeline—he understood that raw talent alone would not let him stand alongside the Saiyans who would one day descend on Earth. He needed a master, a method, and a faction to accelerate his growth 1 2.

His first goal was to find Master Roshi, the legendary Turtle Hermit who had trained Son Gohan and would later train Goku. But the vast, endless ocean made the search nearly impossible. Jiang Yun quickly learned that the easy path depicted in the fanfiction of his past life was a fantasy: one could not simply stumble upon the master's island or beat the "God of Martial Arts" after a few years of casual training. If increasing combat power were that simple, Vegeta would not have stagnated for twenty years under Frieza's command 1. Still, Jiang Yun did not waste his years of wandering. Drawing on the concepts of internal martial arts from his previous life, he developed a unique technique he called "An Jin" (Hidden Force), which allowed him to project double his current combat power in a single strike. He also touched the threshold of ki cultivation, his superior comprehension and mental energy allowing him to sense and manipulate the life energy that flowed through the world 1. By the time he emerged from his initial training, his power level had climbed past one hundred—comparable to Master Roshi himself—and he had learned the Flight Technique, a skill Roshi himself could not master 3.

But Jiang Yun did not rely solely on his own cultivation. He understood that wealth, companions, methods, and location were all crucial to growth 1. Shortly after arriving, he returned to the small village where his new life had begun and gathered the young martial artists there. He shattered a boulder with a single strike to prove the power of true martial arts, and he convinced them to join him in founding the Martial Alliance 2. To fund the faction, he opened a Chinese restaurant called Huayun Restaurant, which soon monopolized half of West City's catering market 2 3. Within a year, he had defeated every youth in the village and rivaled the older generation; within three, his disciples were reaching power levels of seventy or eighty—invincible in the early Dragon Ball setting except for a handful of characters 3. He also trained his disciples in mental fortitude, sending them into the primeval forest for three-month survival trials to temper their willpower, because he believed martial arts must be forged through life-and-death experience—just as Goku grew fastest when facing powerful enemies 4.

Jiang Yun's own training continued in parallel. After a year of seclusion, during which he refined his ki control and developed the "Double-Layer Hidden Force" (a second layer of An Jin that could burst with power sufficient to defeat both Roshi and Master Shen), he decided to gain practical experience outside the dojo 3. He suppressed his cultivation level and wandered the wild lands of the Dragon Ball continent, competing with tigers for food, racing against elk, swimming against sharks, and testing his strength against elephants 7. These exercises honed his speed, efficiency, and power. During this journey, he encountered Yajirobe, a powerful swordsman whose debut combat power rivaled Kid Goku's. Jiang Yun tried to recruit him into the Martial Alliance with the promise of excellent food, but Yajirobe's priorities lay elsewhere 7. More importantly, Jiang Yun climbed Korin Tower and trained under the cat hermit, who possessed centuries of wisdom about ki. Jiang Yun surpassed Korin's expectations, learned to sense energy at a distance, and took an entire jar of Senzu Beans 13. His potential now dwarfed that of any other human on Earth; even Krillin was far behind 12.

As the original plot approached, Jiang Yun shifted his focus toward preparation. He visited Dr. Brief and commissioned both a Gravity Training Room and a spaceship capable of interstellar travel, trading four Senzu Beans for the former 22. He later secured the blueprints for the most advanced spaceship in the universe by stealing Shenron's wish from Emperor Pilaf's gang, ensuring he could travel beyond the solar system 23. He observed Goku and Bulma's adventure from the shadows, saw the Turtle Hermit offer Goku apprenticeship, and eventually introduced himself to the group—declining Yamcha's desperate plea for training by directing him to Master Roshi instead 23 24. When the Gravity Training Room was finished, Jiang Yun underwent six months of intense, methodical training, carefully repairing any physical injuries to maintain his body's potential. He pushed himself to the brink in a mental battle with a simulated version of himself, and his combat power soared to fifty thousand 28. He also deepened his understanding of energy to the point where he could convert ki into a healing ability that guided cellular regeneration, which he began teaching to his disciples 28 29. By the time the 21st World Martial Arts Tournament began, Jiang Yun was already thinking about the wider universe: Frieza was merely a hurdle on the path to godhood, and he had no more opponents left on Earth 27 29.

Plot Synopsis

Founding the Martial Alliance

After arriving in the Dragon Ball world three years prior, twelve-year-old Jiang Yun resolved to become stronger. Recognizing that wealth, companions, methods, and location were essential for cultivation, he decided to establish a faction. Recruiting young martial artists from his village, he shattered a boulder with a single strike to demonstrate his power and convince them. He named the faction the Martial Alliance, appointing Bu Chen as Vice Alliance Master. Jiang Yun also opened a Chinese restaurant, Huayun Restaurant, to provide economic support and food for training 1 2.

Within three years, the Martial Alliance expanded rapidly. Huayun Restaurant came to monopolize 50% of West City's catering market, with the Alliance secretly protecting it. Jiang Yun spent a year in seclusion, reaching a critical stage in his cultivation and developing the Flight Technique and "Double-Layer Hidden Force," raising his power level to over 100 3.

Early Trials and Encounters

Jiang Yun announced a trial for Martial Alliance members: they must survive alone in the primeval forest for three months to forge a true martial heart and improve mental cultivation. He believed that growth came from life-and-death tempering 4. Later, he left seclusion for practical experience, honing his ki control by competing with wild animals. After half a year, he met Yajirobe and attempted to recruit him into the Martial Alliance, offering excellent food as an incentive 7.

During this period, Jiang Yun encountered Tights, a novelist, after saving her from thugs. She pursued him for martial arts stories, and he shared some reluctantly. She gave him a business card from Capsule Corp, and he realized she was Bulma's sister 3 4.

Development of the Gravity Training Room and Internal Affairs

Jiang Yun had long planned to leverage technology for cultivation, particularly the gravity training room. He approached Dr. Brief to commission a room capable of reaching one hundred times Earth's gravity. Dr. Brief agreed, though he noted that interstellar spacecraft technology existed but could only travel within the solar system 22 14. Years later, the gravity training chamber was finally built. Jiang Yun instructed Bu Chen to increase investment and reserve the chambers for core disciples, using a contribution-point system to regulate use 14.

The Martial Alliance grew into a platform organization, issuing tasks with difficulty ratings (1–10 stars) and awarding Bronze, Silver, and Gold Martial Medals. This attracted wandering martial artists and even led the King to request Alliance disciples to train soldiers 15. However, the Alliance encountered resistance from the Crane School, disciples of Master Shen. Jiang Yun chose not to intervene directly, believing the disciples needed to face challenges to grow 15.

Conflict with the Crane School and Expansion

The Martial Alliance swiftly defeated Crane School disciples in West City. Master Shen, shocked by the defeat of his brother Mercenary Tao, considered the Alliance a potential hidden sect. Jiang Yun ordered the Alliance to clear out nearby factions and demanded ten billion in compensation from the Crane School. Master Shen and Mercenary Tao temporarily yielded while vowing revenge 20. Jiang Yun himself broke through in cultivation, doubling his combat power to 2000, and resolved to protect Earth without relying on Saiyans 20.

The Wish on Shenron

Jiang Yun located Bulma and Goku during their quest for the Dragon Balls. Observing from a distance, he witnessed Goku's kindness and the Turtle Hermit's offer of apprenticeship (which Goku declined). After Goku and friends collected all seven Dragon Balls and faced Emperor Pilaf, Jiang Yun appeared, stole the wish, and requested the blueprints for the most advanced spaceship from Shenron. When Goku transformed into a Great Ape and attacked, Jiang Yun easily defeated him 23.

Further Preparations and the Blazing Squad

Over time, core disciples of the Martial Alliance grew in power: 1,000 experts exceeded a power level of 100, 300 surpassed 200, and Bu Chen reached over 300. Jiang Yun developed a modified "Kaioken" technique with reduced side effects, and planned to cultivate healing talents alongside combat skills (Ch. 26). He also continued to refine the Jiang Fist technique, making it more stable and efficient 39.

Dr. Brief made significant progress on the spaceship using the blueprints Jiang Yun provided, but noted that speed would be halved due to the unavailability of Adamantium on Earth 37. This news solidified Jiang Yun's decision to venture into space within two years. He returned to the Martial Alliance and announced the formation of an elite squad, the Blazing Squad, to be selected in one year and led by him into space 38.

Meanwhile, Dr. Gero sought powerful martial artists for experiments, and Master Shen and Mercenary Tao trained Tien Shinhan for revenge against the Martial Alliance 38.

Preparations for the Universe

One year later, the Blazing Squad was assembled, each member possessing combat power exceeding 2,000. Bu Chen reached 8,000. Jiang Yun collaborated with Dr. Brief to develop an AI foundation for a "Virtual Universe" — a virtual network designed to aid training and combat experience. It was planned as a subscription model to generate revenue and accelerate human development 39.

Journey to Qiu Long Planet

Jiang Yun and the Blazing Squad departed Earth for Qiu Long Planet, a mercenary hub. They encountered various alien species at the docking facility. Xiuka, a vice-captain of the Lone Wolf Mercenary Group, approached them, mistaking them for inexperienced wealthy youths. Jiang Yun played along as a carefree young master to gain information and avoid conflict, while his squad remained in the background 40.

Power Progression

Period	Power Level	Key Achievements
Early Years (first 3 years in Dragon Ball world)	Over 100	Developed unique An Jin (Double-Layer Hidden Force) technique, capable of unleashing double his combat power. Mastered the Flight Technique. Established the Martial Alliance and began recruiting disciples. Recognized the importance of foundation and ki cultivation 1 3.
After Underwater Trial & Spirit Energy Enlightenment	Over 1,000	Discovered Spirit Energy—an existence superior to ki present in all things. Achieved enlightenment, absorbing Spirit Energy to cleanse his body and elevate his potential to the level of a super genius, comparable to Son Goku. Developed the Explosive Flame Meteor technique (ki compression), which at its initial test nearly killed him but showed immense destructive potential 11 12.
First Month in Gravity Training Room	2,000	After building the Gravity Training Room (up to 10× Earth’s gravity), Jiang Yun’s combat power doubled in one month, surpassing the power level of Raditz upon his first arrival on Earth. Used the chamber to temper his Earthling physique, aided by Vital Energy 20.
Six Months Intensive Gravity Training	50,000	Through disciplined, methodical training—repairing hidden injuries and building a solid foundation—his combat power leaped to 50,000. Gained a profound understanding of energy, enabling him to develop a healing skill that could mend injuries. Mental energy also improved dramatically via meditation and simulated combat against himself 28.
Pre-Space Mission Training (One Year Later)	120,000	With Dr. Brief’s upgraded Gravity Training Room, his power soared to 120,000—equivalent to Captain Ginyu. Perfected the Jiang Divine Body (a power-boosting technique inspired by the Kaioken), allowing a five-fold boost and sustained tenfold mode by absorbing Vital Energy. Can now convert Vital Energy into ki for combat, achieving near-endless endurance 5 39 43.

Techniques and Abilities

An Jin (Hidden Force)

An Jin is a power-projection technique that Jiang Yun developed through his understanding of internal martial arts, allowing him to emit a secondary wave of force upon striking 1. By layering this projection, he can momentarily amplify his combat power—the "Double-Layer Hidden Force" raises his effective output enough to surpass masters like Master Roshi and Master Shen, despite his base power level being only slightly over one hundred 3. The technique is born from Jiang Yun's exploration of Ki, as the act of projecting An Jin helped him touch the threshold of Ki cultivation even before he mastered it fully 1. However, the amplification is purely transient and cannot sustain a prolonged boost the way the Kaioken can 1.

• Applications
  • Provides a burst of power for critical moments, enabling victory against opponents with slightly higher base combat power 1 3
  • Serves as a foundation for Jiang Yun's understanding of ki manipulation, linking physical force to energy projection 1
• Limitations
  • Only a momentary increase; cannot be maintained in sustained combat 1
  • Places high demands on the user's body, and the underlying principles are not fully understood even by Jiang Yun 1
  • Ineffective against opponents whose speed or reflexes outpace the user's attack, as the technique relies on close-quarters striking 26

Modified Kaioken

Jiang Yun spent three months modifying the Kaioken—a technique originally developed by King Kai that boosts ki intensity at the cost of extreme physical strain—into a form usable by Earthlings 26. By drawing on the principles of his own Jiang Divine Body and the characteristics of this world's ki, he drastically reduced the technique's side effects and lowered the minimum power requirement, allowing even Martial Alliance disciples with a power level as low as one hundred to activate it 26. The modified version still requires mastery of a complex ki circulation path, which Jiang Yun devised through his creative understanding of energy manipulation 26.

• Applications
  • Gives low-power martial artists a temporary power amplification that would otherwise be impossible for humans due to frail physiques 14 26
  • Can be taught systematically within the Martial Alliance, enabling group combat boosts without the violent backlash of the original Kaioken 26
• Limitations
  • Still imposes a physical burden, though milder than the original; the duration may be shorter compared to the original Kaioken due to the gentler energy used 14
  • Learning the technique requires a deep grasp of ki circulation, making it inaccessible to those without proper foundational training 26
  • Cannot reach the high multipliers (e.g., twentyfold) of King Kai's version without risking bodily collapse 14

Jiang Divine Body

The Jiang Divine Body is a comprehensive power-boosting technique that Jiang Yun created by referencing the Kaioken's operational mode—burning ki to intensify energy—while aiming for an amplification comparable to the Super Saiyan transformation 5. In its initial form, it provides a five-fold increase in overall combat power 5. Later refinements, made possible by Jiang Yun's discovery of Spirit Energy and the Breath of All Things, allowed the technique to absorb Vital Energy from the environment automatically, reducing the burden on the user and extending its duration dramatically 39. With Vital Energy support, Jiang Yun can sustain a tenfold mode for extended periods, even achieving a state of near-endless endurance by converting absorbed Vital Energy into ki for combat 39.

• Applications
  • Provides a sustained, overall amplification of combat power rather than a single explosive burst 5 39
  • When supplemented with Vital Energy, can be maintained for long battles, effectively making the user tireless as long as energy is available to absorb 39
  • Serves as a foundation for other techniques, such as the modified Kaioken derived from its refined circulation patterns 26
• Limitations
  • The initial version had a fixed multiplier (three-fold for the precursor Half-Step Crushing Fist) that could not be increased due to physical limitations, though later refinement overcame this 5
  • Without external Vital Energy, the technique still drains the user's own ki and stamina, and the higher the multiplier, the greater the strain 5 39
  • Requires a profound understanding of energy and body cultivation; early Martial Alliance members could not learn it until they had a firm grasp of ki 26

Healing Art

Jiang Yun developed the Healing Art after exploring the resonant qualities of life energy using the Breath of All Things 28. By converting his ki into a gentle, green energy identical to Dende's healing aura, he can guide cellular regeneration rather than merely stimulating cells. The technique successfully heals plants, animals, and humans, and can even regenerate severed limbs—though at a significantly higher ki cost due to the sheer number of cells that must be regrown 29. Jiang Yun designed the skill to be teachable, planning to cultivate medical personnel within the Martial Alliance so that members do not rely solely on Senzu Beans or medical equipment during combat 29.

• Applications
  • Heals wounds quickly and completely, leaving no scar or injury behind 29
  • Capable of regenerating entire limbs, restoring the limb to its original state 29
  • Can be taught to other martial artists, allowing the development of field medics who can treat injuries in the midst of battle 29
• Limitations
  • Ki consumption is ten times higher when guiding cellular regeneration compared to simple stimulation healing; regenerating a limb requires proportionally more energy 29
  • The converted healing ki is permanently consumed—it is not regained on its own, so the user must reserve sufficient ki for the healing process 29
  • Its effectiveness on high-level ki practitioners is uncertain; Jiang Yun himself was unsure whether powerful fighters would heal themselves naturally or resist the external energy 29

Relationships

• Korin: Jiang Yun’s relationship with Korin begins as a formal master–student dynamic but rapidly deepens into genuine friendship and mutual respect. Upon reaching Korin Tower, Jiang Yun impresses Korin with his rapid climb and humble demeanor, stating that he seeks guidance rather than the Ultra Divine Water, which Korin finds sincere 9. Korin accepts him as a student and administers a series of physically and mentally demanding trials—first snatching a bell without ringing it, then catching ten thousand blindfolded fish in the deep sea. Jiang Yun masters both tasks far faster than Korin anticipated, displaying extraordinary adaptability and dedication 10. Korin openly marvels at Jiang Yun’s talent, calling him a “genius” whose seamless technique and deep understanding of ki leave even the veteran cat amazed 10. Over the course of training, Jiang Yun surpasses Korin’s expectations entirely, and Korin acknowledges that he has nothing left to teach—Jiang Yun has already touched upon the essence of energy and achieved a level of spiritual pressure that surprises Korin 13. The two develop an affectionate bond; Korin shows fondness by giving Jiang Yun a pouch of Senzu Beans and later an entire jar, the latter causing Korin to wince at the loss but accept it because of their connection 13. Jiang Yun, for his part, expresses deep gratitude, stating that the training at Korin Tower was “one of the cornerstones for his future as a powerhouse” 13. He promises to return with Korin’s favorite fish and leaves behind a capsule of various fish he caught during his stay, a gesture of care that underscores the warmth between man and cat 13. Korin reflects on Jiang Yun’s growth with pride, contrasting him favorably with Master Roshi, and even speculates that Jiang Yun could one day surpass the Guardian of Earth 13 9.

• Dr. Brief: Jiang Yun’s relationship with Dr. Brief is built on mutual respect, intellectual excitement, and a strategic business partnership that evolves into a comfortable friendship. They first connect when Jiang Yun offers the data for an advanced spacecraft—obtained from Shenron—in exchange for a Gravity Training Room and later a spaceship. Dr. Brief, a world-class scientist, is thrilled by the “exquisite” technology and spends over half a year studying it 25 37. In return, Dr. Brief offers Jiang Yun 20% of Capsule Corp shares; Jiang Yun, demonstrating his humility and lack of greed, negotiates it down to 10%, becoming the second-largest shareholder 25. Their interactions are marked by Dr. Brief’s easygoing, thick-skinned nature and Jiang Yun’s deference to him as an elder. For instance, when Dr. Brief’s wife makes a flirtatious remark, Jiang Yun feels awkward, but Dr. Brief remains unfazed, which earns Jiang Yun’s inward respect 37. Jiang Yun brings the doctor fine cuisine from Huayun Restaurant, understanding his tastes, and Dr. Brief in turn builds a Gravity Training Room small enough to fit inside a capsule—a feat that impresses Jiang Yun 27. The doctor also misunderstands Jiang Yun’s relationship with Bulma, but Jiang Yun wisely refrains from correcting him, knowing that explanations would only entangle the matter 25. Despite the generation gap, their partnership thrives: Jiang Yun entrusts the doctor with his most valuable technological secrets, and Dr. Brief treats Jiang Yun not merely as a shareholder but as a worthy partner and friend, readily agreeing to build him a spaceship when asked 27.

• Bu Chen: Bu Chen is Jiang Yun’s most trusted lieutenant and closest friend within the Martial Alliance. Unlike a mere subordinate, Bu Chen is treated by Jiang Yun as a peer and confidant; Jiang Yun explicitly views him as a friend rather than a servant 38. Bu Chen serves as the vice alliance leader, handling day-to-day affairs while Jiang Yun focuses on training and self-cultivation. Their bond is one of absolute trust: Jiang Yun leaves the Alliance’s response to the Crane School entirely in Bu Chen’s hands, confident in his leadership and strategic judgment 16. When Bu Chen’s brother Bu Fan is nearly killed by Mercenary Tao, Bu Chen fights with an enraged intensity that significantly boosts his power, and Jiang Yun—watching telepathically—allows Mercenary Tao to escape on purpose, trusting that Bu Chen’s victory and the lesson it imparts will benefit the Alliance in the long run 19. Jiang Yun also praises Bu Chen’s progress publicly—Bu Chen’s power level surpasses 300—and encourages him to continue improving 26. Bu Chen, in turn, is utterly loyal; he never pries into Jiang Yun’s mysterious knowledge or origins, positioning himself as a subordinate out of respect, though Jiang Yun consistently raises him to the level of an equal 38. When the time comes to venture into space, Jiang Yun includes Bu Chen in the Blazing Squad, asking gently if leaving Earth will be a problem, and Bu Chen enthusiastically agrees, confident that his brother Bu Fan can now handle the home front 40. Their relationship exemplifies mutual reliance, shared ambition, and deep brotherly affection.

• Tights: Jiang Yun’s encounter with Tights is accidental but leaves a meaningful impression. He rescues her from a group of thugs in West City, and Tights, a novelist, becomes intensely curious about his martial arts, pursuing him for stories to incorporate into her writing 3 4. Jiang Yun is initially reluctant—he is entirely focused on cultivation and has no interest in romance—but he eventually agrees to dine with her at Huayun Restaurant (unbeknownst to Tights, it is his own establishment) and shares a few martial-arts anecdotes from his village 4. Tights is persistent and undeterred by his standoffishness; she gives him her business card before they part 4. Jiang Yun finds her attractive—noting her “slender waist and long legs”—but his mind is set on martial arts, so the interaction remains platonic and transactional: she seeks material for her novel, and he obliges out of a sense of obligation for her earlier pursuit 4. There is a hint of mutual curiosity, but the relationship does not progress beyond this single meeting in the provided context.

• Yajirobe: Jiang Yun meets Yajirobe while traveling toward Korin Tower. They spar, and Yajirobe, an accomplished swordsman, is immediately impressed by Jiang Yun’s immense power. Though Yajirobe is strong, Jiang Yun’s effortless superiority leads to a friendly parting, with Yajirobe acknowledging his strength 8. No deeper bond is formed, but the encounter reinforces Jiang Yun’s growing reputation as a martial artist of extraordinary caliber.

• Bora: As the gatekeeper of Korin Tower, Bora initially challenges Jiang Yun to prove his worth. However, after sizing him up, Bora recognizes Jiang Yun’s potential and invites him to rest before attempting the climb—a gesture of respect from a seasoned guardian 8. The interaction is brief but positive; Bora’s approval is a prerequisite for accessing Korin, and Jiang Yun passes the test simply through his calm, unassuming demeanor.

• Bu Fan: Bu Fan is Bu Chen’s younger brother and a developing disciple of the Martial Alliance. Initially portrayed as mischievous and unsteady, Bu Fan grows under his brother’s guidance and Jiang Yun’s influence. After Mercenary Tao attacks and nearly kills him, Bu Fan resolves to become more responsible, and Bu Chen entrusts him with managing the Alliance’s affairs while the senior members go into seclusion or travel to space 16 40. By the time of the space expedition, Bu Fan’s power level exceeds 3,000, and he chooses to stay on Earth to secure the home front—a decision that demonstrates his maturity and loyalty to the Alliance 40. Jiang Yun does not interact with Bu Fan directly in the provided context, but the trust Jiang Yun places in Bu Chen extends to Bu Fan by extension.

• Master Roshi (indirect): Although Jiang Yun never meets Master Roshi face-to-face in these passages, their relationship is implied through contrast. Korin frequently compares Jiang Yun to Roshi, noting Jiang Yun’s humility and hard work versus Roshi’s lecherous laziness, which pleases Korin 13. Jiang Yun also observes Roshi from a distance when Goku meets him, feeling no excitement—a sign that his own power already far exceeds the Turtle Hermit’s 23. The relationship is one of distant acknowledgment and implicit superiority.

• Mercenary Tao: A purely adversarial relationship. Mercenary Tao is hired by the Crane School to attack the Martial Alliance. He kills Bu Fan (or so it appears) and wounds Bu Chen with a bomb, but Bu Chen, enraged, defeats him. Jiang Yun, watching telepathically, instructs Bu Chen to let him escape—a calculated move that allows Jiang Yun to later issue an ultimatum to the Crane School without unnecessary bloodshed 19. Tao’s defeat cements the Martial Alliance’s dominance and demonstrates Jiang Yun’s strategic ruthlessness.

• Xiuka: An acquaintance from the Saibaman Tournament. Xiuka is a competitor who uses rare Black Cotton Soil and loses to Lan Peiling. Jiang Yun observes the battle and later, to prevent Earth’s exposure to external threats, orders Bu Chen to eliminate Xiuka after the match 50. The relationship is coldly pragmatic: Xiuka is a loose end that must be tied off.

• Dr. Brief’s wife: A minor but memorable character. She flirts with Jiang Yun openly, causing awkwardness for him and Bu Chen. Jiang Yun internally notes her beauty and her resemblance to Bulma, but Dr. Brief’s complete lack of reaction impresses Jiang Yun with the doctor’s forbearance 37. No substantive relationship develops beyond this single interaction.

• Jiang Yun planned to explore parallel worlds using three methods: Future Trunks' Time Machine, the Supreme Kai's Time Ring, or by tearing space through sheer power (as Super Saiyan 3 could do) 27.
• Jiang Yun's "Double-Layer Hidden Force" allowed him to unleash a burst of power sufficient to defeat both Master Roshi and Master Shen, despite having a similar base power level 3.
• Jiang Yun's physical talent is similar to Krillin's, but his comprehension is leagues ahead due to being a transmigrator with strong mental energy 1.
