THERE ARE MONSTERS AMONG US!

Street-fighter Marcus Damon meets a strange dinosaur on the run from the government agency DATS, and defends it from their agent Yoshino Fujieda.

Synopsis
Yoshino, a member of a government agency known as DATS, is dispatched to intercept a renegade Digimon signal. In her investigation, she spots an Agumon and a boy, both beginning to throw punches. Some time later, the two are equally worn out and complimenting each other on their fighting skills. Agumon introduces himself, and the boy reveals himself to be Marcus Damon. Agumon vows to become his follower, seeing Marcus as the first human who does not boast about things that he cannot back up.

Before Yoshi can detain them, they escape. Marcus finds somewhere to hide Agumon while he goes to look for food. Before Marcus can make it back, Yoshi stops him and introduced herself. She takes him to DATS where Marcus is able to meet the leader of the organization, Commander Sampson, and his Digimon Kudamon. They try to convince Marcus that Agumon is a wild creature that will go out of control. Marcus dismisses this and claims that he will be responsible for anything Agumon does wrong. Before an answer could be given, an alarm sounds.

A wild Digimon signal has appeared in the city near where Agumon was left. Marcus takes off looking for him. Thankfully, the signal was not from him, but from Kokatorimon, a giant Bird-type Digimon.

Kokatorimon knocks Agumon out cold, forcing Marcus to explode with anger. He sprints towards Kokatorimon, leaping into the air, punching the bird right in his face. This punch unleashes a great power within his fist! An old fisherman appears, tossing Marcus a Digivice and tells him to use it with his charged DNA to allow Agumon to become stronger.

This power allows Agumon to Digivolve to GeoGreymon. He uses his primary attack to defeat Kokatorimon, reverting him back into a DigiEgg. Commander Sampson notes that Marcus not only has the ability to tame Agumon, but also is able to Digivolve him.
