Who do you believe is the most evolved character. The sources can be tv, film, manga, or even video game. Although the latter is really hard to justify.
I've heard alot of talk of naruto changing as a character and even characters from bleach etc. So I would like to hear who you think has changed the most from start to finish (or recent).
The character that comes to mind for me would be Cordelia Chase from the tv show Angel. Especially if you take her character from Buffy as the start point.
