where? ^^

he fought against kakashi and run away

Kabuto has proven himself to be a skilled and cunning ninja, particularly because of his medical abilities. His skills are said to rival those of Kakashi Hatake on more than one occasion. He has been shown to be able to kill ANBU members with relative ease and even mockingly stated he could handle at least 10 ANBU members. During his battle with Tsunade, she remarks that Kabuto's jutsu sense and sharpness may have surpassed hers, even in her prime. Through keen observation, Kabuto can quickly determine the situation at hand. Even when up against a stronger opponent, he can take advantage by quickly exploiting their weakness. Kabuto is also very adaptable, as when Tsunade flipped his nervous system signals, he managed to regain control of his body quickly, a feat that impressed even Tsunade.
