Its Rapid Fire capabilities and Accuracy have increased dramatically, along with several appearance changes. King Rekuso's basic paint color has been changed, since being upgraded from Rekuso; the colour scheme has been changed from light red to a more maroon/burgundy color. The holding pads on the foot armor had been expanded, along with its shoulder units.
