Neptune

Neptune is the cheerful, food-loving protector of Planeptune. Known for her airheaded nature and impulsive attitude, she often appears clumsy or ditzy in her daily life. However, she undergoes a dramatic transformation into Purple Heart, a version of herself that is mature, serious, and powerful. While this form possesses immense raw strength and a confident, prideful edge, Neptune's initial overconfidence can sometimes lead to unexpected vulnerabilities.
