SuperDarkKnightmon

Super DarkKnightmon is the fusion of DarkKnightmon, SkullGreymon, and SkullSatamon. In this form, DarkKnightmon's cape turns into demon wings, while his weapons are enhanced: his Shoulder Blade is enlarged, with SkullSatamon's ribs as accents, and the Twin Lance is turned into a jousting lance featuring the skull and bones of SkullGreymon.
