Koh Grif (グリフ・コウ, Gurifu Kou?) is a character from the BakuTech! Bakugan Manga. He uses Haos Kilan Leoness and is Sho Grif's younger brother. He later teamed up with Harubaru, Raichi, and his elder brother to form Team Dragaon.


Koh appears older than his actual age due to his very muscular build. He has yellow eyes and spiky blue hair fastened by pink clips. Just like his older brother, he is often seen wearing his white uniform with blue linings.

After his Kilan Leoness evolved into Shield Leoness, Koh dyed his hair blonde and wears his uniform with yellow linings to match his newly evolved Partner Bakugan's color.

Years later in the series, after Shield Leoness evolved into Ogre Leoness, Koh dyed his hair back to blue to match his newly evolved Partner Bakugan's color, while he seems to keep his uniform as before. .


BakuTech! Bakugan[edit]

Koh is the son of the head of the Grif Financial Group. He is an Elementary School Student in the Fifth Grade (making him around 11 years old). He uses the Haos Attribute and his Partner Bakugan is Kilan Leoness. He does not look like an elementary school student because of his imposing figure and body build. He approached Harubaru with haughtiness and underestimation but when he was defeated, he apologized and befriended Harubaru.

He refers to himself in third person "This Koh Grif" (Kono Kou Gurifu) in the manga, "Waga" in the anime and his second person pronoun is "Omae."

Koh refers to Sho as "Aniki" (Older Brother). After that, the two enrolled to the Bakugan Dojo. Koh takes great pride in his brawling skills and his shooting skill is "BakuTech Lion Rock."


BakuTech! Bakugan[edit]

Koh makes his debut alongside Sho in the fourth episode, The Grif Brothers. He brawls against Harubaru Hinode in a Critical K.O. type of brawl which he lost. After that, he befriended Harubaru.

In the fifth episode, Koh was overwhelmed by the interruption of Tohga to which he crashed into a wall. This angered his older brother, Sho, who fought against Tohga with Raichi and Harubaru with the intention of avenging him but to no avail.

In Quilt's temple, Koh and his older brother were not seen much in between falling down the trap door and returning to the Bakugan Dojo by sunset. It was also not revealed if they were given any tests by Quilt.





BakuTech! Bakugan (Anime)[edit]

Koh fought five battles but has only won once. He is an extremely powerful Brawler in terms of sheer force but he loses due to being overpowered.
