As the Sannin, Tsunade, Jiraiya, and Orochimaru battled against each other, Naruto battled Kabuto Yakushi and performed the Rasengan on him, but when it did, Kabuto used his Medical Ninjutsu: Strong Beam to cut a major artery to Naruto's heart which caused it to almost kill him. As Tsunade tried to save him, the demon fox realized its surroundings were getting darker and darker. It didn't take long for it to realize that Naruto was dying which greatly scared the beast. Despite Naruto being saved (by Tsunade or by himself), this became the demon fox's first brush with mortality.
