Mia is a sarcastic, funny person who lies a lot. She is also very environmentally friendly,and loves animals,stating that she will never love anyone as much as her ginger cat, Fat Louie. Mia is worrisome, paranoid about Michael dumping her for either a smarter girl,a girl who is willing to "do it" with him or a "party girl". Also, Mia is quite romantic, writing love poems to Michael, who secretly loves her too, and insecure, constantly thinking of herself as a biological freak.
