Cerberumon was the first Digimon encountered under the influence of Cherubimon, whom the DigiDestined in Frontier had to battle. They stumbled upon him after their arrival in the Digital World, when he attacked Fire Terminal and absorbed the Fractal Code for Fire Town while looking for something called a Spirit. During this process he also attacked Bokomon and Neemon. When Takuya tried to lead Cerberumon away from the others, he found the Spirit of Fire, whic gave him the power to become Agunimon for the first time. He then battled Cerberumon, who however had the advantage with the Portals of Darkness attack before being beaten and purified by Agunimon which reverted him to a Digi-Egg. Takuya used his D-Tector to release the Fractal Code which restored the village and the nearby area.
