Baiyi's appearance could be changed at will, but he usually preferred three appearances.
The first was his classic pumpkin-head-plus-emoji-face form, used before the Voidwalkers and his closest friends for no reason other than familiarity.
The second was a spectacularly grandiose and magnificently gilded armor that would gleam in golden hues under every ray of light. Such an awesome and awe-inspiring look was for public appearance.
Finally, exclusively for his family members and his mistress, Baiyi assumed the look of a sophisticated, gallant man — a bourgeoise, cultured man with profound sensibilities and finely-aged handsome look. This was also the body where every essential biological function was complete.
