Background / History

Lin Yuan was a 23-year-old livestreamer from Earth. He was transported into the Dragon Ball world when a One-Star Ball he had purchased emitted golden light and engulfed him. He awoke in a tomb-like castle, escaped into a forest, and discovered a system that rewards completed missions with Battle Power and Perfect Saiyan Bloodline progress. 1 2

Initially possessing a Battle Power of only 3, Lin Yuan chose to wait for Bulma and Goku rather than search for them blindly. After meeting them, he gave Bulma his Dragon Ball and joined their journey. He fought Oolong, Yamcha, Rabbit Boss, General Blue, Mercenary Tao, and other threats while pursuing increasingly demanding training. 2 4 5 7 12 14

Lin Yuan used Shenron to obtain Instant Transmission and a physical enhancement, although he initially lacked enough ki to use the technique. He later trained with gravity equipment, Korin, Mr. Popo, and Kami, prioritizing ki control, martial arts fundamentals, and combat efficiency over raw power alone. 7 10 14 21 33

Following his victory in the World Martial Arts Tournament, Lin Yuan founded the Ultra Instinct Dojo in West City. He recruited Nam as its manager and instructor, later accepting Tien Shinhan and Chiaotzu as trainees. The dojo expanded to over 130 disciples during his extended training at Kami’s Lookout. 18 19 20 21 23

Lin Yuan became engaged to Launch after returning from the Demon Realm, where he and Goku rescued Princess Misa and defeated Ashura. He and Launch later had a son, Lin Yiqi. 23 39

By the Saiyan conflict, Lin Yuan had become one of Earth’s strongest defenders. He killed Raditz with a single punch, defeated Vegeta after exploiting the Great Ape transformation’s weakness, spared him, and later fought Turles during the Tree of Might crisis. 38 45 46 50

Appearance

Lin Yuan is a tall, leanly muscular young man with a build that emphasizes agility as much as strength. Before his transmigration, he stood 178 centimeters tall and commonly wore black clothing. 1

• Neat short black hair.
• Deep, bright eyes.
• High nose bridge and thin lips.
• Distinct but not overly bulky musculature.
• Frequently wears weighted training gear or a gravity suit during cultivation. 13 15

Personality

Lin Yuan adapts quickly to unfamiliar and dangerous circumstances. Though initially frightened after arriving in the tomb-like castle, he immediately focused on escaping, assessing risks, and finding shelter. 1 2

He is highly goal-oriented and strategic. He plans his training around known future threats, uses deception against stronger opponents such as Mercenary Tao, and removes Raditz’s scouter and spacecraft for later research and tracking. 5 14 38

Despite his desire for power, Lin Yuan has a strong protective streak. He defends friends and civilians, establishes a dojo to develop Earth’s martial artists, rejects the Tree of Might’s planet-killing power for personal gain, and spares Vegeta. 7 19 20 45 50
