Strange as it sounds, my answer would be Dorothy Gale of Kansas. Not as played in the 1939 movie, but as I discovered her in the Oz books when I was a kid. She was just a regular kid living out in the middle of nowhere, but she was also smart, gutsy, plain speaking, and succeeded by being kind and helpful, rather than clawing over others.
Naturally, I developed a crush on her. :-) (Oh, and Dorothy Gale is blonde, dammit!)
She was a regular person from the rural midwest who managed to have grand adventures while also being true to herself. It was her adventures that started my lifelong fascination with reading, and that led directly to me wanting to document the adventures of others. My first fanfic was a Mary Sue about a trip to Oz -- I've been spinning stories ever since. Without Dorothy, it's hard to tell what kind of person I would have become, but I wouldn't be me.
