Bio: Mao Onigawara is the main character of Earth Defender Mao Chan. She works for the defense force as a member of the ground defense force. Mao's clover is green and it allows her to transform and use abilities to defend against cute aliens. What type of advantages she has being "ground" has not really been made clear.

Opinion: She's determined. Despite her failures and mistakes, she doesn't give up. She's also cute as a button. And while she takes things lightly considering she is a child. She is very serious when it comes to her job.
