Kotetsu Hagane

is a Chunin from Konohagakure. He spends most of the time with his partner Izumo Kamizuki.

Appearance
Kotetsu wears a bandage across his face over the nose. At one point, Asuma, Izumo and Shikamaru ask him about this and remind him that he didn't use it when he was a kid. Later he agrees to take the bandage off but then Shikamaru states that knowing it would only be troublesome much to Kotetsu's chagrin, so the reason for the bandage over the nose remains unknown.

Part I
Izumo and Kotetsu first appear disguised as Genin, trying to convince those planning to take part in the Chunin Exams not to bother. Team 7 recognizes that they have cast a genjutsu on the area, prompting them to give up in light of the group's skill. They then act as examiners in the first test. When Tsunade becomes Hokage, Izumo and Kotetsu start doubling as her assistant and as guards to the front gates of Konoha. The anime indicates that they are easily ignored or duped by those using the Transformation Technique while on the job.Alex Garcia was his brother!!!=)

Part II
Izumo and Kotetsu are assigned to a Niju Shotai team with Asuma Sarutobi and Shikamaru Nara. Their mission being to find members of Akatsuki, they do just that. The team tracks an Akatsuki duo to a bounty station, where Izumo and Kotetsu stab Hidan during a sneak attack. When Hidan survives, they pull back and watch Asuma fall prey to Hidan's jutsu, unable to help him. They instead engage Hidan's partner, Kakuzu, but are easily captured and must be rescued by Raido Namiashi and Aoba Yamashiro.

Personality
Kotetsu is almost always seen alongside Izumo, and is characterized as being the irresponsible and less conscientious one of the duo. He is seen, for instance, at the end of Shippūden Episode 79, shirking his duties and eating a large jar of syrup by himself in the Jonin lounge. Similarly, Izumo admonishes Kotetsu's lack of pride in his work when the latter complains that they are simply the Godaime's errand-boys or "gophers". He has also been depicted as being the more carefree and more volatile of the two.

Abilities
During his fight with Kakuzu, Kotetsu summons a large shell-like weapon from a carrying scroll. Since he is quickly captured by Kakuzu, it is unclear how skilled he is with it.

Trivia

 * During the Naruto OVA that came as a bonus for Naruto: Ultimate Ninja 3, Kotetsu engages in fight with Gaara, resulting in a humiliating defeat and a few broken bones.
