Duskmon

Duskmon is one of the antagonists in the anime Digimon Frontier. He is a demon Digimon that has skulls for his head, hands, and feet. He has eyes for his shoulders, chest, and his feet. His real red eyes can be seen in the skull head. He weilds two red blades as swords.

Duskmon first appeared as a sillouette. Then after the battle against Petaldramon and reverted back to Arbormon, Duskmon appeared and cold-heartedly killed Arbormon and scanned his data. The Digidestined tried to fight back, but they were no match for Duskmon.

Later on, he was looking for Koji, and it revealed that Duskmon was Kouchi, Koji's brother. With the help of Aldamon, Beowulfmon defeated Duskmon and Kouchi returned to normal.
