If KO'd he slashes them vertically up in half instead.
Koh Kazama, often just called Samurai Koh, is a man truly ahead of his time... literally. Koh comes from an ancient time where he was considered the strongest warrior in a ninja village near Wildefort. One time the village got attacked by a menacing demon who had been locked up for centuries, Murasame. Koh stepped forth to beat the demon, and he managed to land a fatal blow, killing him. Murasame, with his last strength, opened up a portal to the future where Koh was sent to, getting back at him that he will never be able to protect his clan so that is slowly dies out. In the present Koh, although confused at first, he became accustomed to life in the present.

- His main appearance is based on Takamaru from The Mysterious Murasame Castle, with a mix of Samurai Jack from his titular series.
- His backstory closely resembles that of Jack, being a person who traveled forwards in time. However this time he simply lives there and works as a kendo teacher. This is similar to Jack's role in Powerpuff Girls Doujinshi.
- His surname was not revealed until Warriors of Babylon. Kazama is assumed to be the original name of Fūma Kotarō, the leader of the Fūma clan, and notorious for having killed Hattori Hanzō.
