Abilities
Kakkō excelled in all shinobi abilities, in ninjutsu, taijutsu, and genjutsu. This made him a highly influential and powerful figure in Iwagakure. He was highly belligerent and had great experience in battle, allowing him to use advanced tactics to defeat his enemies. He also fought using retractable blades attached to his arms.

Background
He used his skills while fighting Team Minato, led by Kakashi Hatake. First he tried to extract information from Rin using genjutsu, but this proved unsuccessful. Later when Kakashi and Obito Uchiha attempted to rescue Rin, Kakkō managed to corner them and even kill Obito. However, once Kakashi had received the Sharingan, the tides turned and he was killed by Kakashi's Chidori, but not before Kakkō cut in two the famous White Light Chakra Sabre Kakashi had inherited from his father, Sakumo Hatake.
