Hinata, Sakura and Ino. A lot of the women in Naruto seem really weak and never get their own fights.
Well hinata still needs her chance to shine (trying to fight pain was really brave and all, but she got owned

) and sakura.... Well sakura needs to act like the main heroine again (vs sasori she was b/a) and id like to see her do something original, not just be a mini tsunade.
Ino will never get a 1v1 cuz shes purely a support nin.
Konan's really underrated imo. I think its because the only fights she was shown in were the worst possoble matchups for her: her sensei eho knew her jutsus weakness and tobi whose powers basically completely hardcountered hers. And she almost managed to kill tobi despite that. I mean, she ripped off an arm, broke part of his mask, and forced him to sacrifice an eye. O yeah and split the freakng water like she was moses or something
Mei and tsunade are also underated, madara said that tsunades attack was even stronger than raikages. And meis boil release is soooo deadly.
