Digimon: The Movie

Four years before the original seven children's transportation into the DigiWorld, a Digi-Egg emerged from the Kamiya's computer, and hatched into a Botamon the next morning. Kari Kamiya managed to communicate musically with the Botamon using her whistle, and it accepted them as friends. After eating a bunch of candy bars, it Digivolved into a Koromon.

Able to speak now, Koromon constantly asks questions and eventually becomes friends with Tai and Kari. The following night, however, Koromon digivolves into Big Agumon.


The Dark Masters attack the facility where he is housed, and Gennai flees with the eggs in hand. He is taken to File Island, where he hatches into Botamon who eventually digivolves into Koromon. During this time, he plays with the other Digimon as he holds the Digivice that belongs to Tai, waiting for his partner's arrival.

Koromon finally meets his partner Tai while he is unconscious from his first arrival and tries to protect him when Kuwagamon attacks them. He digivolves to his main form Agumon when Kuwagamon corners him on the face of a cliff.
