Colleen is a superb voice actor. Up until recently, I didn't know much about her, but now that I do I'm glad. She's a splendid voice actor who does some of my favorite characters.
She provided the voice of Sora for 'Digimon'. This was my favorite of all of her performances. Sora was sorta the den-mother type character. Yeah she was a bit tom-boy, but she was also the calm character who tried to keep the group together. Collen did a fantastic job on Sora. She really made Sora lovable.
Jazz Fenton (Danny Phantom) is the perfect older sister. Good grades, peppy spirit, and maturity of an adult. Jazz is also caring and watch out for Danny. Collen does a good job on Jazz. She knows how to change your feeling about Jazz at an instance. At one momment you want to yell get out the screen, and at the next, you start loving her again.
The most current voice of Collen's is Suzie. A lot of people can't stand Suzie and I'm one of them. The thing about it though, is Collen helps you hate Suzie. She gives Suzie one of those voices that makes you fell like punching her.
In short, Collen's fantastic. I'm keeping my fingers cross that she'll be a bigger star.
