Mestre Kame is an ancient and wise martial arts master who serves as the first teacher of Son Goku in the events of Dragon Ball Movie 4: The Path to Power. He lives in seclusion on a small island known as Kame House, accompanied by a sea turtle, and is recognized as the creator of the legendary Kamehameha technique, which he spent decades perfecting. In this film, his background is that of a legendary fighter who has trained several notable warriors, including Goku’s adoptive grandfather. His personality blends deep wisdom with an exaggerated, comical lechery, often pursuing attractive women and indulging in adult magazines. Despite this humorous flaw, he is fundamentally disciplined, selfless, and devoted to the Turtle School philosophy that emphasizes hard work, humility, and constant growth. His primary motivation is to guide Goku and Krillin toward becoming balanced fighters, teaching them that true strength comes from daily effort and moral integrity rather than raw power alone. In the story, he first appears after Goku and Bulma help his sea turtle return home, and he repays them by granting Goku the Flying Nimbus cloud. He then accepts Goku and Krillin as students, putting them through a rigorous training regimen of manual labor and physical challenges that builds their foundation. When the Red Ribbon Army threatens the world, Mestre Kame provides strategic advice and uses his abilities—such as the Kamehameha and a temporary muscle-bound state—to aid the young heroes, though his main role remains that of a mentor rather than a frontline combatant. His key relationships are with Goku, whom he treats like a grandson and instills with core values, and Bulma, who frequently becomes the target of his comic advances. Over the course of the movie, Mestre Kame demonstrates his development by showing unwavering courage when facing threats far beyond his own power, but he does not undergo a dramatic transformation; instead, his wisdom and experience remain constant as he passes the torch to the next generation. His notable abilities include the Kamehameha wave, which he uses to extinguish a raging fire on Mount Frypan, and his capacity to dramatically increase his muscle mass and energy output for short bursts, allowing him to deliver immense physical force and ki attacks. He also possesses centuries of combat knowledge, enabling him to read opponents and adapt his strategies quickly.
