Movie
Description
Oolong is an anthropomorphic pig with pale pink skin who typically dresses in human clothing such as trousers, button-down shirts, and suspenders. In Dragon Ball Movie 4: The Path to Power, an alternate retelling of the original Dragon Ball story, he is introduced early in Goku and Bulma's journey. While the pair is traveling through a forest, Oolong blocks their path in the disguise of a large bull and demands the girl, Bulma. When Goku fights back, Oolong changes into a robot and then a bat, but his transformation time runs out and he is revealed as a pig. Bulma then convinces him to join their quest as a traveling companion, and Oolong becomes part of the group traveling in his house-wagon.

Before this adventure, Oolong attended a shapeshifting school where his improper behavior, involving stealing the teacher's underwear, got him expelled. This history catches up with him during the story when Puar, the shapeshifting companion of the desert bandit Yamcha, recognizes Oolong and scolds him for his perverted antics at the school. His tendency toward selfishness, laziness, cowardice, and lecherous humor makes him a constant source of comic relief, and he often looks for the easiest and most comfortable path for himself rather than the bravest one. Despite these flaws, he is not entirely self-centered, and his time with the group gradually brings out a more loyal side.

Oolong's motivation throughout the film is largely practical and self-serving. He joins Goku and Bulma because their search for the Dragon Balls seems like a convenient way to secure an easy life, and he often dreams of wealth and comfort. He is not a fighter by nature and prefers to avoid danger whenever possible, relying on his wits and his shapeshifting to slip out of trouble. His cowardice frequently puts him at odds with Goku's fearless enthusiasm, but his ability to change form makes him genuinely useful to the team, particularly for deception, escape, and creating diversions.

His key relationships in the movie are with the members of the traveling group. With Bulma, he shares a pragmatic partnership, as both are more interested in comfort and convenience than Goku is, and Bulma is often the one who keeps him in line. With Goku, he begins as an opportunistic hanger-on and slowly becomes a reluctant but genuine friend who stands by the boy when it matters. His reunion with Puar adds a comedic layer to his past, as the two share a history as classmates at the shapeshifting school, and Puar has little patience for his old habits. He also interacts with Master Roshi, with whom he shares a similarly lecherous appreciation for Bulma's wardrobe mishaps, and he travels with Yamcha, Puar, and the others when the group is captured by the Red Ribbon Army.

Oolong's role in the story is that of a supporting companion and comic relief. He provides transportation in his house-wagon, helps the group survive the journey, and is present during several key confrontations. When the heroes are captured by General Blue's forces, Oolong is imprisoned alongside Bulma, Yamcha, Puar, and Roshi, and he takes part in their escape. He remains with the group through the final battle against the Red Ribbon Army and is present when the Eternal Dragon is summoned at the climax, witnessing the wish that revives Android 8.

His development across the film is subtle. Oolong begins as an opportunist who only cares about his own benefit and safety, but through his repeated experiences with Goku and the others, he becomes more willing to stay with the group in difficult situations. While he never loses his cowardly and lazy personality, his loyalty grows, and he proves that even a selfish shapeshifter can become a dependable member of the team.

Oolong's most notable ability is his shapeshifting, which allows him to take on the appearance of almost anything, from animals to machines. However, this power has a strict limitation: he can only hold a transformation for about five minutes before reverting to his true form, and he needs time to recover before transforming again. In the movie, he uses this ability to attack in the form of a bull, to flee as a bat, and to create various disguises. His combat skills are minimal, so he depends on trickery and escape rather than direct confrontation. This combination of a powerful but limited ability, a self-serving attitude, and a hidden streak of loyalty makes him a memorable and enduring presence in the film.
