She has a small pink beak and large, curved eyelashes. Her personality is cold, dominant, and manipulative. She is haughty and arrogant, viewing those she considers beneath her with open disgust and disdain, not hesitating to call them 'peasants'. She has an evil streak and is prone to fits of anger, like stamping her feet.
