SkullKnightmon is an Undead Digimon. It is a big brother who exchanged cups of brotherhood with Axemon. As a knight which excels in cunning, its behavior is based on its policy, "Those who are knights must fight. Even more than fighting, they must win", and generally speaking, it puts importance on the outcomes in which it wins. Moreover, it will unabashedly perform any kind of unclean act to arrive at that result. It specializes in combat which capitalizes on the size of its body, and the manner in which it dives at the opponent's chest, swinging its "Spear Needle", shows off the unthinkable actions of a knight that has forgotten its pride.

SkullKnightmon is patterned off of the archetypal undead skeleton knight. It is clad in black, full-bodied armor with a cape. It wields red lances as its hands, and its chest is a skull with red eyes.
