|Debut||Dragon Ball: The Magic Begins|
One day after training with his grandfather Sparkle on Mount Paozu, he goes out to get a crocodile for them to eat. When walking home he was almost ran over by a jeep driven by Seetoe who ends up being the first girl he has ever seen. When he gets back to his house he sees that his Dragon Pearl was stolen and that his grandfather was kidnapped. He goes with Seetoe to find them using her device that can track Dragon Pearls.
While traveling they are attack by Zebrata and Malilia and several other soldiers who destroy Seetoe's jeep forcing them to walk. While walking they meet Jade who was being chased by a shapeshifting man they named Piggy. Monkey Boy fought him in a fight and easily beat him and he offered to help them. Next Monkey Boy met a bandit named Westwood and his bird named Miss Knowwhat. Monkey Boy and Westwood put out an even fight but Westwood dropped his guard and ran in defeat when Seetoe showed up. Monkey Boy and the others went to the house of the Turtle Man to ask for his help in defeating the evil forces taking over Jade's village.
When they showed up the Turtle Man tells Monkey Boy that Westwood told him he wanted to fight him and steal his Dragon Pearl. Monkey Boy says that he did not want to and the Turtle Man made him step on the Magic Cloud to show if he was honest. Seeing that the cloud let Monkey Boy on and didn't allow Westwood on Turtle Man gave Monkey Boy the cloud. After Turtle Man gave them his and Westwood's Dragon Pearls, Zebrata and Malilia's forces come to his island destroying his house and taking the Dragon Pearls. Monkey Boy had Seetoe and Jade get on the Cloud while Piggy held onto the Magic Pole so they did not get caught in the explosion.
Seeing that Turtle Man, Westwood and Miss Knowwhat survived the explosion they decided to all join forces to go to Jade's Village and defeat King Horn the one responsible. Monkey Boy and Westwood fought Malilia once getting into the village. After Piggy killed her using a gun, they ran to the castle where they engaged in battle against King Horn. During the battle, his grandfather was released and King Horn resurrected all the people he killed to kill the gang. Monkey Boy used his magic cloud and attacked King Horn while he was using the ray bringing everybody back. After the spell was broken King Horn was defeated by Turtle Man and Sparkle and the dragon was summoned restoring the village. In the end Westwood challenges Monkey Boy to another match and he gladly accepts.
- Monkey Boy already knows how to fly in the beginning, but Goku didn't learn how fly until late in Dragon Ball
- Any hints of him being a Saiyan were completely absent since he had no tail in the film and never transformed into the Great Ape. As well as the fact that the film was released before the point in the manga that explained Goku's origin.
