Agumon

Agumon is a fictional character from the Digimon media franchise. He is the Digimon partner of Marcus Damon and a main character in the Digimon Data Squad anime series. Agumon usually calls Marcus "Boss" because Marcus takes care of and protects Agumon. Agumon is a bipedal yellow Tyrannosaurus rex-like creature with green eyes and stubby legs and tail. He wears red training bracers.

Agumon adores his partner Marcus, and considers himself to be "Marcus's employee". He even refers to Marcus as his "Boss".

In the first episode, he is referred to by the code-name of Raptor-1 by DATS.

This Agumon in particular holds true to the given description of a common Agumon being somewhat aggressive.

Being the main digimon character in the series, Agumon is always the first amongst the partner digimon to reach a new level. Unlike the other partner digimon in Digimon Data Squad, Agumon was easily accepted into Marcus' family when he was discovered, and is even given free reign of the Damon household.

Although Yoshino tells Marcus that Digimon can only eat special Digimon food, Agumon tends to eat practically anything, including Marcus's mother Sarah Damon's fried eggs. Agumon's obsession with eating sometimes results in comical moments when Agumon (or Koromon, in one situation) attempts to eat Marcus's head.

In the final episode, Marcus' DNA gives Agumon a new appearance. An outline of a dragon surrounds him, and he is given fiery bird-like wings and a dragon-like tail. In addition, Marcus can ride him, using straps attached to Agumon's wristbands to control his movements. Whether this is a super charge of Marcus' DNA or a new digivolution stage is unknown. Fans like to refer to him as "Agumon Burst Mode".
