Agumon (2006)

Agumon (アグモン)
A unique Agumon which has bound red leather belts around its arms, its maturation is presumed to differ from its traditional evolutions. As it's still growing, its power is weak, but it has grown hard, sharp claws on its hands and feet, and demonstrates its power in battle. Its Special Move is spewing flaming breath from its mouth, striking the opponent (Baby Flame). Also, it can amass "Baby Flame" in its mouth and then spew it out all at once (Baby Burner), which is much more powerful.

Etymology
Agu: May come from aguagu (アグアグ) which is the sound of biting.
