Agumon

Agumon (アグモン) is a Rookie level Digimon.

Description
Agumon is a short and stout dinosaur-like Digimon, standing at about 3 feet tall. It has amber orange skin and light green eyes, as well as flattened forearms with broad, three-clawed hands - though early artwork for the Digimon virtual pet depicted its hands with four claws - and distinct pectoral muscles. Its legs and arms are shown to be very vascular. Its tail is stubby, and its head and snout are almost as large as the rest of its body.

Digimon World
Agumon is the first Digimon that challenges Mameo to a battle upon leaving File City and entering the Native Forest (800 HP). After beating it in a fight, it joins the city and opens the Item Keeper store.

Several Agumon work for Ogremon as members of his bandit gang. After Mameo clears the Ogre Fortress, the gang of Agumon decreases to two members, and finally separates from their boss when it quits its profession to patrol the city.

Agumon is available as Digimon Partner evolving from Koromon. A player is able to start out with Agumon as their partner is they chose that they prefer "Day" during Jijimon's question at the start of the journey.

An Agumon is the Meaty Troops gatekeeper and keeps guard at the entrance of the Guts Wastes, just outside of the Meaty Troops' base.
