MASTER ROSHI
MR
The ancient, perverted martial arts master living on a tiny island who invented the legendary Kamehameha wave after fifty years of concentration. Underneath his tropical shirts, sunglasses, and shameless antics lies the world's greatest living martial arts grandmaster. Disguising himself as "Jackie Chun" in the World Martial Arts Tournaments, Roshi enters the ring specifically to defeat his young pupils, teaching Goku and Krillin the eternal lesson that there will always be someone stronger in the world to strive against.
MASTER THROUGH THE ARCHIVE //
MARTIAL ARTS SCHOOLS //
Open page →Roshi's training is almost aggressively unglamorous. Goku and Krillin deliver milk, plow fields, swim through dangerous water, dodge hazards, study and perform everyday labor while wearing weighted turtle shells.
He is not rushing them toward a secret finishing move. He is building stronger bodies, better endurance and the discipline to keep training without making fighting their entire lives.

The Breakdown
Roshi's lesson is to train hard, study hard, eat and rest properly, then enjoy life too. The Kamehameha is his famous technique, but the foundation is what makes his students dangerous.

Drunken Fist
Open →Suiken · Erratic Stance Taijutsu · Jackie Chun (Master Roshi)
A deceptive martial stance modeled after traditional folklore. Jackie Chun mimics severe intoxication - stumbling, staggering, and swaying uncontrollably - to mask precise, unpredictable striking angles that throw off an opponent's analytical timing.
Hypnotic Lunar Illusion
Open →Saimin Jutsu · Neural Suggestion Stance · Jackie Chun (Master Roshi)
A high-level hypnotic technique deployed during the 22nd Tournament. Jackie Chun uses rhythmic hand movements and voice suggestion to trick a lycanthropic opponent (Man-Wolf) into perceiving a smooth bald head as a full moon, permanently curing his condition.
Evil Sealing Wave
Open →Mafuba · Dimensional Containment Kinjutsu · Master Mutaito, Master Roshi, Tenshinhan, Kami
A sacred forbidden art created by Master Mutaito to seal demonic entities inside air-tight containers (like rice cookers or vacuum flasks). The caster swirls green energy to physically bind the target before guiding them into the vessel. The extreme physical toll guarantees the death of the user upon execution.
Kamehameha
Open →Kamehameha · Energy Concentration & Projection · Master Roshi, Son Goku, Krillin, Yamcha
The quintessential energy attack of the franchise. The user draws latent internal ki into a tight, vibrating sphere between cupped hands at the hip before thrusting palms forward in a concentrated beam. Master Roshi spent 50 years perfecting the technique, which he used in Episode 8 to obliterate Fire Mountain.
SAGA SUMMARIES //
Open page →Roshi Enters Because Goku Needs to Lose
Open →Jackie Chun · Master as opponent
Master Roshi does not enter the tournament as Jackie Chun because he needs prize money or because he secretly wants glory. He enters because Goku and Krillin are improving too quickly, and he is terrified that winning too easily will convince them there is nothing left to learn.
That makes the final against Goku less about deciding who is strongest and more about Roshi trying to preserve Goku's hunger to improve. He is willing to exhaust himself, destroy the moon, and nearly lose the disguise entirely to make the lesson stick.

Why it matters
Dragon Ball's first major tournament ends by telling its hero that losing can be useful. Goku does not walk away humiliated. He walks away excited that somebody stronger still exists.
Rival Schools, Not Just Rival Fighters
Open →Roshi vs. Shen · Goku vs. Tien
Master Shen has trained Tien and Chiaotzu to treat strength as domination and assassination as a respectable career. Roshi's students have been taught to train hard, live fully and keep looking for somebody better.
That argument plays out through the bracket. Yamcha is injured deliberately. Chiaotzu cheats on command. Jackie Chun eventually steps away because Roshi realizes Tien is already beginning to question the man who raised him as a weapon.

Why it matters
The tournament has an ideological winner before it has a bracket winner. Tien has to decide what kind of martial artist he wants to be while he is still fighting Goku.
COMBAT LEDGER //
Open page →Goku vs. Jackie Chun
Open →21st Tenkaichi Budokai · Episodes 26–28
Goku finally meets an opponent who can answer almost everything he does. Jackie Chun mirrors the Turtle School techniques, survives the Great Ape disaster by destroying the moon, and still has enough experience left to win the final exchange by the smallest possible margin.
The Breakdown
The fight works because Roshi is secretly trying to teach while fighting for real. He needs Goku to believe the world is still larger than him, but he cannot fake the loss or the lesson means nothing. The result is Dragon Ball's first great 'winning is not the same as progressing' fight.
