Giant Fish are a breed of fish that are often seen in a lake on Mount Paozu. These fish are blue and purple in nearly all versions in which they appear; in the movie Dragon Ball: The Path to Power, Giant Fish are colored green and yellow.
One is caught by Goku in the first episode of Dragon Ball to be Goku's lunch, just before his encounter with Bulma. The fish plays a very memorable figure of Goku's childhood in Mount Paozu and has been reenacted in alternate versions of the beginning in the movies such as Dragon Ball: Curse of the Blood Rubies and Dragon Ball: The Path to Power. This Giant Fish is the first living thing to be killed on screen.
A number of very similar looking fish of the same breed have been seen throughout the series, such as in Dragon Ball Z: Cooler's Revenge where one is caught by Goku (ironically he says that it is "a little on the small side but just right for making sushi") and the episodes "Goku's Ordeal" where another is caught by Gohan. In "Hour of Temptation", one is hit by Cell's Energy Wave fired at Vegeta. In "Memories of Gohan", Goku plays a prank on Krillin making him think that a Giant Fish eats him and that Krillin is next. In "I am Saiyaman", a Giant Fish is seen having been caught by Goten. In "He's Always Late", Goku is eaten by a Giant Fish after he saves a pterosaur egg falling from a waterfall, but he then manages to escape from the fish's mouth with the egg.
Video game appearances
Giant Fish are enemies in Dragon Ball: Revenge of King Piccolo, Dragon Ball: Origins 2, and Dragon Ball Z: Attack of the Saiyans. Three types of Giant Fish appear in Attack of the Saiyans: the regular Giant Fish, Wild Fish, and Sand Fish.
Giant Fish can be seen in the Grandpa Gohan's house stage in Dragon Ball Z: Budokai 3 and Dragon Ball Z: Infinite World, and in background of the main menu of Dragon History mode in Dragon Ball Z: Budokai Tenkaichi 3.
- The first Giant Fish seen in the series speaks in the Japanese version, but he is silent in the English versions. The green one in Dragon Ball: The Path to Power is the only one who talks in the English dubs.
- In the live-action movie Dragon Ball: Ssawora Son Goku, Igyeora Son Goku, the fish is normal. In the second live-action adaption, Dragon Ball: The Magic Begins the fish was replaced by a crocodile.
