1. Tsunade, been my number one since I saw her
2. Anko - Orochimaru is my favorite character and she's his disciple so
3. Mei - Highly respected and powerful fighter (before you start factoring in all of the human-gods that apparently exist now, she would have been powerful)
4. Temari - Femme Fatale of first series
5. Tayuya - When you think about it her power was pretty badass. Sound based genjutsu that would completely paralyze her opponent. If only it weren't rendered useless by wind.
