Movie
Description
Master Roshi, also known as the Turtle Hermit, is an ancient and wise martial arts master who plays a significant role in the film Dragon Ball Z: The World's Strongest. His background establishes him as a legendary figure in the world of martial arts. Fifty years before the events of the movie, Master Roshi was considered the strongest fighter on Earth. This reputation is central to the film's plot, as the villainous Dr. Wheelo and his assistant Dr. Kochin specifically target him based on outdated information, believing his body would be a suitable vessel for transplanting Wheelo's brain.

In terms of personality, Master Roshi embodies a blend of contradictory traits. He is the archetypal wise old man, possessing centuries of experience and martial arts knowledge. He is deeply kind-hearted and cares for his students and friends as if they were his own family. However, he is also famously perverted, often distracted by beautiful women and spending his leisure time consuming questionable media, a trait that provides much of his characteristic comic relief. Despite these eccentricities, he is capable of great seriousness when the situation demands it.

Master Roshi's motivation in The World's Strongest is straightforward: to protect his friends and defend the Earth. He is kidnapped by Dr. Kochin, who uses Bulma as a hostage to force his compliance. Once brought to Wheelo's fortress, Roshi is forced to fight against Kochin's three Bio-Warriors to demonstrate his strength as a potential host for Wheelo. Although he puts up a decent fight, he is ultimately overwhelmed and defeated while outnumbered. His role evolves from being a captive to becoming an active participant in the final battle. After being freed, he joins Goku, Krillin, Piccolo, and Gohan in their assault on Dr. Wheelo's giant robotic body. In a notable moment of teamwork, he joins Goku and Krillin in firing a triple Kamehameha wave, known as the Master-Student Kamehameha, at their foe. He also personally intervenes to stop Dr. Kochin from shooting Bulma and Krillin, proving that his skills remain valuable even in the face of overwhelming power.

The film highlights Master Roshi's key relationships with the younger heroes. He is the original martial arts master to both Goku and Krillin, and this dynamic is central to the movie's action. Although both students have far surpassed their teacher in raw power by this point in the timeline, the film shows Roshi fighting alongside them as an equal comrade, demonstrating respect and camaraderie. His relationship with Bulma is also featured, as his lecherous nature is played for humor even in the midst of a crisis, and she is instrumental in revealing to the villains that Goku is now the world's strongest, not Roshi.

While Master Roshi does not undergo significant personal development within the confines of this single film, his role reaffirms his enduring legacy. By the time of Dragon Ball Z, he is typically overshadowed by the Saiyans and other powerful warriors, often relegated to the role of a wise but perverted background figure. The World's Strongest is notable for being one of the few instances in the Dragon Ball Z era where he is given the opportunity to fight seriously and contribute directly to the defeat of the main villain, reminding the audience that beneath his frail and comical exterior lies a mighty warrior.

Master Roshi possesses a number of notable abilities. As the inventor of the Kamehameha, he can unleash a powerful ki blast that is capable of immense destruction. In this film, he demonstrates proficiency in hand-to-hand combat, holding his own against multiple Bio-Warriors simultaneously. He has also mastered the Afterimage Technique, moving at super speed to leave a decoy behind. When he fights at full strength, he can enter a Max Power form, where his muscles bulge dramatically, granting him immense physical strength and a more powerful version of his signature Kamehameha. Although he rarely uses this form due to its toll on his aged body, it represents the pinnacle of his martial power.
