Digi-destined in File Island

A boy, T.K., with his Digimon friend, Patamon, was separated from the rest of the digi-destined. They visited a hatchling ground after they got permission from Elecmon, a Digimon who lost to Patamon in tug-of-war. They had fun playing until Leomon and Ogremon trapped T.K. and Patamon, but soon, the other digi-destined came to help. After they escaped, T.K. and the rest decided to finish off Devimon, an evil Digimon, and saved File Island.
First they thought they had won, but then Devimon popped out of the Fortress. He started attacking, and so did the Digimon. Every Digimon digivolved into their Champion stage. Patamon was the only Digimon to stay at rookie level. T.K. and Patamon watched the other Digimons fought Devimon. They almost beat Devimon, but the evil Digimon came back and defeated the other Digimon. Leomon started to attack also, but Ogremon was hidden somewhere in the rocks and blocked Devimon from Leomon. Now, Devimon thought it was only T.K., Patamon and himself, but suddenly, the other Digimon bit and beat up Devimon. Devimon looked defeated, but he got up and blew the Digimon away. The evil Digimon now grabbed for T.K., but Patamon was between them and made Devimon get him.
In his hands, there was suddenly white blinding light. Patamon was Digivolving at last. Patamon, the little Digimon was a mighty Angemon. He told Devimon that the good forces were more powerful than the evil forces. The evil Digimon did not believe this, so Angemon used his power and destroyed Devimon. Everybody cheered, but Angemon disappeared also. T.K. found a Digi-egg in front of him. It was Angemon. The day was saved.
