Cerberumon

Cerberumon was a minor villain in Digimon Frontier and Data Squad.

Appearance
Cerberumon is an Ultimate Class Digimon that looks like a black Cerberus or a three headed dog with six claws on each paw, three of them are longer than the other.

Digimon Frontier
When Takuya, Tommy, J.P., and Zoe were in the Digital World for the first time, a Cerberumon was the first Digimon that attacked them. He first attacked the Digimon Bokomon and Neemon. Takuya tried to save them but this caused Cerberumon to attack him. Takuya eventually found the spirit of fire and Digivolved into Agunimon. Both of them fought each other, but Cerberumon tried to give himself and advantage by using Portal of Darkness because darkness is his homefield advantage. Even with that advantage Agunimon still defeated him and purified hid data.

Digimon Data Squad
When Marcus, Thomas, Yoshi, and Homer were sentence by Baromon, he unleashed a Cerberumon on them. Homer's Digimon, Kamemon freed the other Digimon and attacked Cerberumon. Agumon couldn't Digivolve because Marcus couldn't punch Cerberumon. He manage to punch him because Cerberumon was having a bullfight with Yoshi. Just when Agumon was going to Digivolve Baromon told Cerberumon to stop and decided to spare the DigiDestined when he found out that Marcus is related to Spencer Damon.
