For reference almost all COs have extremely different designs in the japanese version of AW1
Most of the designs are the same from AW2 onwards except for Olaf who wears his western outfit but still has white hair, Grit who always wears a cowboy hat and Sonja who always has glasses and wears a red outfit
Also interesting, AW1 and 2 were actually released in North America first BEFORE the Japanese versions which were both cancelled and later released after a few years, so technically the NA designs were what everybody got first
