Edo Tensei

Even though she has been returned from the dead and deprived of free will, Fuu retains glimpses of her cheerful and carefree nature. When Naruto penetrates the shared consciousness of the tailed beasts, she behaves kindly, smilingly recalling the last moments of Son Goku and Roshi before sealing, and joyfully introduces herself together with her biju Chomei. However, under Tobi's control and with the implanted chakra receivers, her actions become mechanical and coordinated — she is no longer an impulsive chatterbox, but an obedient weapon with a single field of vision through the Rinnegan. Nevertheless, Fuu's soul inside the resurrected body remains friendly and open, which manifests in the moment of meeting Naruto: she shows no malice or hatred, but rather curiosity and joy at communicating with another jinchuriki. Her signature phrase 'There is no word for defeat in Fuu's dictionary' now sounds bitter — for she has already been defeated, killed in life.
