Digimon Adventure (movie)

Two children receive a strange egg through their computer, which hatches into their very first Digimon, leading to the night that would change their lives forever.

Synopsis
In Highton View Terrace, Tokyo, in the Kamiya residence, two kids named Tai and Kari are awoken late at night when a strange egg comes out of their computer. The next morning, Tai cannot believe his eyes when he realises the egg is real. Whilst their mother is out, the egg seems to develop a mind of its own when it escapes Kari's grasp and rolls away. It then hatches into a Botamon (though the kids do not know this), and immediately latches onto Tai's face. Tai throws it off, and it runs under the nearby bed. Kari eventually gains its trust with her whistle, and begins feeding it chocolate, causing it to digivolve into Koromon. Now out of food, Kari steals the food belonging to the cat, Miko, and gives it to Koromon, who thanks her by latching onto her face as well. Though, Miko soon finds Koromon with its food, and lashes out at him, and then Tai, who tries to protect him. Soon after, Koromon introduces himself, and tells Tai and Kari that he is a Digimon from the digital world. They don't really understand this, and later head to bed, but Koromon suddenly digivolves into an unusually large Agumon, and begins roaming the streets, causing destruction on a small scale. Before he manages to cause any real casualties, a large bird Digimon called Parrotmon appears out of a huge orb in the sky. Agumon lashes out, which only angers the bird, causing it to destroy an overhead bridge, covering Agumon and the two kids in rubble. Though out of the rubble, Greymon appears in Agumon's place, and begins fighting back against Parrotmon. After a few minutes, Greymon is knocked out, and only awakens when Tai blows Kari's whistle. He then lets out a blinding fire breath attack, and the two Digimon vanish, leaving Tai and Kari alone amongst all the destruction.
