SkullKnightmon Cavalier Mode is an Enhancement Digimon. It is the "Assault Mode" (突撃形態 Tougeki Keitai?) in which SkullKnightmon is mounted on Axemon. Its main purpose is for getting close to the opponent by speeding like a bullet, defying all obstacles. After charging at the opponent with its "Kiba Braver", Axemon transforms into SkullKnightmon Mighty Axe Mode to fight joined with SkullKnightmon. If the progress of a battle becomes unfavorable it changes back into "Assault Mode" and hastily retreats from the battlefield. Axemon, who possesses limitless stamina, does not tire, so it can repeat this process without accident, and for a short while Axemon's way of fighting is more feared on the battlefield than SkullKnightmon's.
- Kiba Braver (キバブレイバーKiba Braver? lit. "Cavalier Braver"): Cuts the opponent apart as it charges at them.
