Movie
Description
The character known as Follet Tortuga Mutenroshi is the elderly martial arts master who lives on a small, isolated island. His name, Follet Tortuga, translates to Turtle Hermit, a title reflecting his reclusive nature and the large turtle shell he carries on his back as part of his training attire. He is a bald, bespectacled old man with a thick white beard and mustache, and despite his small stature and frail appearance, he possesses immense strength and holds the title of the God of Martial Arts.

In the story of Dragon Ball Movie 2: Sleeping Princess in Devil's Castle, Follet Tortuga serves as the catalyst for the adventure. At the beginning of the film, the young warriors Son Goku and Krillin arrive at his island home seeking to become his students. Demonstrating his traditional and often mischievous nature, the master refuses to simply accept them. Instead, he sets them a difficult condition for their training: they must journey to the menacing Devil's Castle and successfully rescue the beautiful Sleeping Princess who lies imprisoned within. This task is not born of malice but is a test of their courage, resourcefulness, and willpower, qualities he deems necessary for a worthy student.

His motivations are rooted in his role as a guardian of martial arts. He is not a main combatant in this particular film, but his presence looms over the plot, as the entire quest is undertaken to earn his tutelage. He is the legendary master who taught Son Gohan and the Ox-King, and he is the creator of the signature Kamehameha wave, a powerful energy attack that concentrates the user's ki into a destructive blast. He is also implied to be the strongest martial artist on Earth at this time, though his students do not witness the full extent of his power directly in this adventure.

Regarding his personality, Follet Tortuga is famously a lecherous old man. He has a well-documented obsession with beautiful women, which often provides comedic relief. He spends his free time watching aerobics programs on television and reading magazines featuring models in bikinis. It is strongly implied that his request to rescue a sleeping princess was partly motivated by the expectation that she would be a beautiful young woman. Despite this flaw, he is a figure of great wisdom and a genuinely good-hearted mentor who cares for the development of his students. His key relationships established in this story are primarily with Goku and Krillin, whom he pushes to their limits even before they formally begin their training.

In terms of notable abilities, even in his relaxed state, his power level is far beyond that of ordinary humans. He is the inventor of the Kamehameha, a technique that Goku uses throughout the film after having learned it from him previously. He has also achieved a form of longevity that has allowed him to live for over three hundred years, and he has supposedly gained eternal life from drinking a legendary elixir, meaning he does not die from old age, though he can still be harmed or killed. He is a master of the "Double Image" technique, moving at incredible speeds to create illusions of himself to confuse opponents. The character sees little development within this specific movie, as he serves more as a goal and a challenge for the younger heroes than as a protagonist who changes himself.
