My favorite is the female path of Nagato. She is the most badass of every female and deserves to be with Sasuke Uchiha and probably would have been if that bastard Jiraiya never killed her.
I can't put finger on who is my favorite female character :nuts:
I never pay that much attention to them unless they are badazz, like mikasa or they are in a pairing i have interest in.
Temari because she is not useless and has an interesting ability; never been a fodder; always been a badass.
Mei, Tayuya, Anko, Tsunade, Konan are cool too.
But Temari is the best imo; both in personality and badassary; also very skilled and strong.
