GeoGreymon

GeoGreymon is Agumon's Champion level form. GeoGreymon is an orange Tyrannosaurus rex with orange eyes, and spikes on his arms, shoulders, and jaw, with blue tips on them. He has blue stripes on his legs, arms, neck, torax, mouth and tail. He wears red training bracers and a brown helmet with three horns and multiple spikes on it. The helmet also has red stripes, and the spikes have red tips.

GeoGreymon first appears during Agumon and Marcus's fight against a large Kokatorimon. This is when Marcus activated his DNA for the first time. Marcus was given his Data Link Digivice, and with it, he was able to help Agumon digivolve into GeoGreymon for the first time. After the first battle with Merukimon, GeoGreymon is often replaced by one of his digivolved forms so this form is used less and less in battle.
