Belle~ I have explained these reasons so many times it's practically engraved in my head, lol. I like Belle because she is exactly the person whom I want to be because she's a independant person with a beautiful personality, a personality I just adore. The rest of the reasons are pretty much surrounding on why she's my fave princess.
Gwen Stacy (Spider-Man remake)~ Gwen is an intelligent person who gets the job done. 'Nuff said.
Ginny Weasley (HP)~ Ginny belives in so much and I think I like her the best in the last two films. She comes across as a strong girl and that she fights for a good cause no matter what they are up against. Ginny is also awesome because she usually doesn't except defeat.
Maximum Ride~ I loved her series so much and it's amazing that she was so strong of a leader even when it looked like all hope was lost. She can fly in to rescue and she never gave up, no matter what. Max rules!
Mulan~ I know this is technically another Disney character, but I just adore her. She does whats right in unselfish acts, even saves China by being true to herself. I have always admired her without doubt.
I'll probably think of more later.
