Movie
Description
Olong is an anthropomorphic pig who appears in Dragon Ball Movie 1: Curse of the Blood Rubies as a minor threat who gradually becomes a reluctant companion to the main characters. He is small and round, with a pig's snout and ears, and he relies on trickery rather than physical strength to get what he wants.

His background is shaped by his time at a shape-shifting school, where he was a classmate of Puar, the shape-shifting companion of the desert bandit Yamcha. Olong was expelled from the school for stealing the teacher's underwear, an early sign of the selfish and mischievous nature he carries into the film. Within the movie, he is first encountered in the form of a large monster accosting a young girl named Pansy. He uses his transformation ability to appear far more intimidating than his true form, a tactic he employs to terrorize villages and demand young women as brides.

Personality wise, Olong is lazy, cowardly, greedy, and self-serving. He avoids direct conflict whenever possible and prefers deception, escape, and personal comfort over any kind of ambition or genuine malice. His motivations are simple: he wants to look after himself, avoid danger, and enjoy easy pleasures, which makes him more of a nuisance than a serious villain.

His role in the story begins when Goku and Bulma come across him threatening Pansy. Goku proves his strength by destroying a large tree, causing Olong to flee, but Goku chases him down and knocks him over with the Power Pole, exposing his true pig form. From that point, Olong is pulled into the group's quest. He allows the travelers to use his camp for the night, and it is there that Pansy explains the crisis facing her homeland under King Gurumes. Later, when Master Roshi demands that Bulma show him her chest in exchange for his Dragon Ball, Oolong transforms into a copy of Bulma to trick the old master, a key moment that allows the group to continue their journey. He also accompanies the others to King Gurumes' palace, where he is shot down along with Bulma and Pansy during the attack by the king's air force.

His key relationships are with Goku, Bulma, and Puar. Goku sees through his disguise and defeats him easily but does not treat him as an enemy afterward, which sets the tone for his acceptance into the group. Bulma orders him around and puts his powers to practical use, while Puar is a former classmate from his shape-shifting school days, which establishes a shared history among the animal-like characters of the early story.

In terms of development, Olong shifts over the course of the film from a small-time menace into an ordinary member of the traveling party. He does not become a brave fighter, and his self-preserving instincts never disappear, but his involvement in the quest softens his role from troublemaker to companion. His flaws are played for comedy rather than genuine danger.

His defining ability is shape-shifting, which allows him to take the form of almost any person, animal, monster, or object. This is how he appears as a monster to frighten villagers and as Bulma to deceive Master Roshi. However, his transformations are temporary, lasting only about five minutes at a time before he reverts to his natural pig-like form. He has little combat skill, so he depends on disguises, quick thinking, and running away when threats arise.
