Well, normally I'd answer with one of my own characters (definitely Annie), but since a lot of you aren't familiar with the crazy universe inside my head, I'll use a fictional character that isn't mine. I have to say Lilo from "Lilo and Stitch." I may not be a little Hawaiian orphan girl, but I'm definitely a lot like her personality-wise. I'm very odd, have a tremendous imagination, and most people really don't understand me (I'm not saying that in the teenage sort of "you don't understand me!" emo way, I really mean it - most people just don't understand why I am the way I am). I gravitate towards weird creatures who are also very misunderstood, and I like taking pictures of fat people. Well, I don't actually take pictures of random fat people very much, but I find them very interesting and would if I wasn't worried that they'd take it the wrong way and get offended and yell at me. I tend to wreak havoc wherever I go, even though my intentions are usually good. And I have some pretty unusual books in my room too (no road maps of Iowa though).
Either that or Luna Lovegood. She's pretty eccentric and creative too, but loyal to her allies. Only I'd hope my dad wouldn't turn in my friends just to free me.
