Princess Mandie (pronounced "Man-die") is a minor antagonist in The Fairly OddParents. She's an alien princess that Mark Chang left on the altar because he considers her beautiful appearance to be hideous. She wants to marry Mark so that she can cast him aside and rule Yugopotamia herself.
Mandie is the princess of an alien planet of Boudacia (pun on bodacious) and is what is to be considered as a "Deadly Beauty". She somewhat resembles in a science-fiction variation of the TV character “Xena: Warrior Princess”. She carries a flaming sword which is her preferred choice of weapon, and yet she possess many other kinds of weapons such as bazooka guns, a double bladed axe, a bomb, and she even grows diamond claws on her finger nails, similar to the Marvel Comics characters "Wolverine" or “Lady Deathstrike” (or the villain Nadira from Power Rangers Time Force). She also has rockets built into her boots that allow her to fly.
Mandie has yellowish-green skin, elf-like ears, long purple hair, light green colored pupils, a pair of curled antenna on her head resembling that of a butterfly, and black lipstick. She wears crystal earrings and a headdress, an emerald (light blue in picture) colored corset, skirt, and knee-high boots. Mandie also has sharp teeth, shown whether she is angry or smiling.
Mandie was looking forward to being married to her future husband to be Mark Chang of Yugopotamia. However, once Mark fled the planet and left her at the altar, her true colours comes out. When her heart gets broken, she becomes extremely angry and vengeful that she will kill anyone in her path, and what she hates the most is being left alone at the altar.
