Negative Emotions Sensing

When Naruto Uzumaki achieved his Nine-Tails Chakra Mode, he gained the ability to sense negative emotions. He was able to sense Kisame Hoshigaki while he was hiding inside Samehada even though Kisame and Samehada shared the same exact chakra signal. According to Madara Uchiha, Mito Uzumaki also possessed this ability.

Trivia
