A Dark Knight Digimon. ChaosDukemon is a Dukemon whose armor is a dark grey with a purple cape. Its holy lance "Gram" has been replaced with the evil Balmung Spear, and the Gorgon Shield takes the place of Aegis. A theory says that it and Megidramon are the same being, and that its horrible aura manifests either as a dark knight or a dark dragon depending on the viewer.
ChaosDukemon is referred to as ChaosGallantmon in English material.
