Background & History

Li Shu arrived in the Dragon Ball world with an Undying Body and instantly acquired Japanese language proficiency. He intentionally starved himself nearly to death to test the achievement system, earning Ki Sense in the process. Soon afterward, Son Gohan found him on Mount Paozu; Li Shu claimed to be an orphan and was taken into Gohan’s home alongside Son Goku. He disclosed that he was a Saiyan and offered to teach Goku how to retain his sanity during Great Ape transformations. 2

He spent five years on Mount Paozu, sparring with Goku while avoiding especially painful training. After Son Gohan’s death, Li Shu comforted Goku through his grief. Goku eventually learned to control his Great Ape state while retaining his mind. 4

Seeking system rewards and Senzu Beans, Li Shu followed Korin to Korin Tower. He defeated Bora respectfully, flew to the tower’s summit, and received a Beginner Senzu Bean Can and Dimensional Storage Space. He repeatedly challenged Korin for the Super Holy Water, ultimately distracting the cat guardian with yarn; drinking the water earned him a Dojutsu draw and Battle Eye. The pain of awakening Battle Eye left him unconscious for more than a month, causing him to miss Shenron’s summoning. 7 8

Personality

Li Shu is calculating, opportunistic, and highly conscious of system mechanics. He deliberately engineers situations that may trigger achievements, upgrades useful items through risky probability-based attempts, and studies the conditions behind hidden missions. His desire for strength often takes the form of efficient preparation rather than conventional discipline. 2 15 34 47

He is intensely afraid of pain, a weakness made worse by the hundredfold pain sensitivity imposed by his Undying Body. He avoids unnecessary suffering, relies on Senzu Beans and painkillers when possible, and seeks Pain Immunity through the Dragon Balls. Even so, he can remain conscious and fight through extreme pain when cornered. 26 29 32 33

Li Shu can be courteous in formal combat, as shown in his fight with Bora and his treatment of Yamcha after defeating him. However, his pursuit of achievement progress also leads him to intimidation, torture, and vigilante punishments against criminals and Red Ribbon Army soldiers; these methods disturb Goku. 7 18 38 40 45

• He discovered hidden achievements may be triggered by altering established events or interacting with non-original figures. 34
• He later concluded that strong emotions can help trigger achievement missions. 36 47
