Digimon Adventure (デジモンアドベンチャー Dejimon Adobenchā?) is the first Digimon film. It was released in Japan on March 6, 1999, a day before the television series began airing in Japan. It was released in the United States on October 6, 2000 as the first part of Digimon: The Movie.
 
This film acts like a pilot episode for Digimon Adventure. The first story focused on Tai and Kari Kamiya four years before their adventure in the Digital World. It shows their first encounter with Digimon and what happened to them (as well as the other children that saw it became the other DigiDestined) when they participated in their first Digimon battle after raising a quickly growing Botamon. In the story, that Digimon hatches from a Digi-egg and eventually evolved into Greymon to fight a Parrotmon who appeared in the city. The movie was used in episodes of Digimon Adventure to explain why Tai and company became DigiDestined.
