Koga Gou

About:
Koga has been, for a long time, Kariya's best friend. He's even taken in one of Kariya's projects. In the present, Koga is a very strong man who controls the doll maned Dark. Generally, he's a very nice man, and he even follows through with Kariya's plan. However, Koga tries to stop him after he realizes that Kariya's gone too far; wanting to blow up Soul Society.

Style:
A tank top with pants and boots, that's the gruff Koga for you. He also wears, what seems to be, head phones around his neck.

Power:
His doll, Dark, is basically heavy metals balls that form a skeleton to make a female machine. She can take on a couple of forms, one of them resembles a lady while the other resembles a preying mantis, although her face never changes. She's a very cynical character that could care less if you died. Koga is very caring towards Dark. Oh, and she also comes in a final form which is basically a giant axe which Koga wields.

History:
A long time ago, Kariya had stopped by his home and dropped of a boy that was a bount. At first they didn't get along, but they slowly did and Koga might have seen this boy as a son figure. Unfortunately, the young man died when he tried to make his own doll. He had no control over said doll and it killed him.
