Andrealphus is a lanky, peacock-like avian demon with a short light blue beak, and cyan eyes that both lack pupils and irises and have periwinkle upper-eyelids. His feathers appear to be mostly white with slicked-back, short, light periwinkle hair with a few dark blue spots. He also sports long tail feathers colored in a gradient of cyan-to-white with no outlines. Inside his beak, his tongue is the same color. Andrealphus wears an extravagant, dress-like coat that is mostly shades of light blue.
