Kongō

was one of the Three Wandering Ninja in the Land of the Moon.

Plot overview
He is first seen with Ishidate when they witnessed the bodyguards escape from the soldiers. He was then seen again attacking Naruto Uzumaki and managed to knock him out cold by punching his head through the sand. After that, he fought Rock Lee and defeated him easily. Kongo then went after Hikaru Tsuki and was shot by one of his "arrows". He only laughs and takes the arrow off and snaps it. He then gets ready to kill Hikaru but immediately stops when he felt the surge of power from Naruto. Naruto releases his Nine-Tailed Fox chakra and connects multiple hits on Kongo. After that, Kongo was then lying on the shore. Naruto walks up to him and tries to finish it but is interuppted by Karenbana who uses her Many Flowers in One Bloom technique, but Naruto easily blows the technique away. Later, he is seen retreating with Karanbana and Ishidate after they succesfully captured king Michiru Tsuki

Later on, he was seen again. This time, he was trying to stop the team from going on in the castle. He encounters them later on in the castle and plans to fight them, but Rock Lee says that he'll be his opponent. He then receives a blow from Lee but it seems to not have an effect all. After that, Lee takes off his weights and makes connecting hits at Kongo with blinding speed. Next, Lee takes him down with a powerful blast from his Nunchaku. But, that didn't take out Kongo and in return (saying that Lee was a stupid little idiot) he throws around Lee and makes heavy, critical hits, which manages to knock out Lee. Somehow, Lee was able to recover from the assault and then proceeded with his attack. Lee then used the fifth gate to take out Kongo with connecting nunchaku hits and used the Strong Thunder Lotus Chain which knocked him completely unconsious, his fate afterward is unknown
