Kōga

Koga (鋼牙 Kōga) is the young leader of the southern yōkai-wolf tribe, which is nearly wiped out by Kagura and Naraku. He first meets InuYasha as an opponent in battle, but becomes a reluctant, occasional ally despite maintaining a strong sense of rivalry with the "useless dog" about their relative combat strengths as well as Koga's persistent courtship of Kagome.

Although Koga always flirts with Kagome and getting Inuyasha mad, it is seen that he has promised Ayame, another wolf demon to be his wife. Koga had promised Ayame, when she was younger, that he would someday make Ayame his wife. Later in the episode, Koga tries to get Ayame to leave by saying he will only marry someone who can see the Sacred Jewel Shards. At the end of the anime it is revealed he did infact marry Ayame.

After suffering serious wounds, Koga is partially restored by three Shikon shards embedded into his legs and right arm. The shards are eventually taken away from him by Naraku, gravely weakening him; he leaves and disappears from the manga, after telling Kagome that she may leave InuYasha and come to him at any time.

He wears brown wolf fur and has a tail that is like a bushy wolf's tail. Koga has a brown wolf fur head band and he wears silver and black armor. Koga also has brown wolf fur as shoulder plates. He carries around a sword but is never seen using it. His ears are pointed just like a wolf's.

Name Meaning

 * The 鋼牙 means "steel fang".

Abilities

 * Whirlwind - Koga's method of transportation. Whenever on the go, he is enveloped in a high-speed tornado. Despite its effectiveness, Koga never actually uses it in battle.
 * Goraishi- A claw that Koga earns from his ancestor spirits so that he can avenge the deaths of his comrades and destroy Naraku. It creates energy blasts that are equal to that of a fully-powered Wind Scar. The claw shields him, barely, from Naraku's corruption of the jewel but it was only able to protect him once. The Goraishi has literally become a part of Koga.
