Kō Hyūga

is a shinobi of Konohagakure and is also a branch member of the Hyūga clan.

Appearance
Unusual for a Hyūga, Kō has light hair. It is short with backwards spikes. He has the Byakugan and his nose is broad and well-defined. He wears the standard Konoha uniform and flack jacket and he wears his forehead protector on his head as a bandanna.

Invasion of Pain arc
When Hanabi Hyūga and Hiashi Hyūga were away, he was assigned as Hinata Hyūga's bodyguard during Pain's attack on the village. When Hinata went to try and help Naruto Uzumaki fight Pain, Kō called her back. He claimed that she would only be a burden to Naruto. Later, he watched in horror with his Byakugan as Hinata went ahead regardless. He was unable to restrain her, due to a broken leg he had sustained when Pain used his Shinra Tensei on the entire village.

Trivia

 * In the anime, Kō's appearance was changed. Instead of having light, spiky hair and a broad nose, he has a small nose and dark, straight hair. This made him look identical to the unnamed Hyūga that was with Sakura after Pain destroyed Konoha, hinting that the anime creators either conflated the two characters, or mistook them for one another.

Quotes

 * (To Hinata) "It would be my everlasting shame if anything were to happen to you while Hiashi and Hanabi were away."
