Balto: Jenna is willing to fight a furious bear far larger than she is and has no qualms with standing up to Steel, something many of the male dogs in the film are too afraid to do. Sadly, she ends up fading into the background in the other two films.
Bolt has Penny (the onscreen version, anyway), particularly in the opening. Mittens has her moments as well.
Dragons Fire And Ice: Princess Kyra, who is an exceptional hand-to-hand fighter, is very skilled with a staff and kali sticks, and can wield friggin' fire.
Galatea in 2-D: Penny. When the hero struggles all out with her, she's still able to overpower him.
Shrek: Princess Fiona has a BadassAction Girl moment in the first movie, but kind of stays behind in the second and third movies. Now in Forever After, the fourth movie, holy crap...
