Princess Mandie stands about the height of a human adult. She has yellow skin, elf-like ears, and a pair of curled antenna on her head resembling that of a butterfly. She wears an emerald colored corset, skirt, and knee-high boots. She also has crystal earrings and a crystal headdress, and she wears black lipstick. She has long purple hair, and green colored pupils. She is considered by Boudacians, humans and fairies to be a very beautiful girl, but hideous by Yugopotamians.
She was looking forward to marrying Mark Chang of Yugopotamia. However, once Mark fled the planet and left her at the altar, her true colors came out. When her heart gets broken, she becomes extremely angry and vengeful that she’ll kill anyone in her path, and what she hates the most is being left alone at the altar. She would find that person who she is after and either force them to marry her or kill them, which is why her name is pronounced "Man-Die" instead of the normal name "Mandy". Despite her rather beautiful appearance, she has an extremely aggressive nature and short temper.
