2. Lightning

Lightning is the protagonist and narrator throughout the Final Fantasy XIII trilogy. She is only the second female main character in the numbered series, the first being Terra from Final Fantasy VI. This pink haired beauty was forced to raise her sister alone after the death of her parents. She later became a soldier which resulted in her neglecting her duties as her sisters guardian. After realizing that her sister had been branded a Pulse Fal'Cie, she resigned from the Guardian Corps in hope to rescue her sister. 

Lightnings whole character is very reminiscent of Cloud Strife from Final Fantasy VII. There is even a Cloud outfit that you could get in Final Fantasy XIII: Lightning Returns. As a result she acts more masculine than most traditional female Final Fantasy characters. She still has her feminine charm though. As the series went on her dress became gradually more revealing. 

See what I mean? Lightning did not look like this in FF XIII.
