Gō Koga

is an character in the anime-exclusive Bount arc. He is a Bount, and the one closest to Jin Kariya.

Appearance
Koga has red hair cut short, with a spiky orange center. He is a very large and muscular man, usually wearing a sleeveless shirt and large headphones around his neck.

Personality
Despite his size, this man is kind. When he took Cain in, he tried to protect the young man from his doll, but failed. Ever since, he refuses to hurt children, which is why he turned against Kariya. After realizing he was the only Bount left, he apologized for their harsh actions.

History
In 1800s, while still going under the name Claude Gaugain, Koga was living in a countryside somewhere in Europe. One day Kariya, known at that time as Eugene Currier, payed him a visit and brought Cain with him. He asked Koga to take care of Cain and teach him how to live as a Bount. Koga initially refused, saying that Bounts should live on their own and train themselves. However, Kariya managed to convince him. Before leaving he gave Koga a book, which detailed doll summoning instructions. Initially Koga's relationship with Cane was rather rocky, but with time they developed a master-apprentice bond. Some time later Koga bought Cain his own coat without asking. Cain was delighted with the gift, but some rude villagers tried to take it from him. They attacked Koga with no success, and retreated. A mob charged Koga's home soon after that and he released Dalk to fight them. Cain was impressed with Dalk and wanted a doll of his own. Koga gave him the book for summoning one, but told him not to try on his own. Cain disobeyed him though and before Koga could save him, his doll turned on him. Before turning to dust, Cain reached out to his master and told him he didn't want to die. Koga greatly suffered the loss of Cain and later joined Kariya's cause.

Synopsis
Koga was first seen trying to take Yoshino Sōma and Uryū Ishida back to Kariya's mansion. He briefly fought Yoshino's doll, Goethe, but used Dalk to overpower her. After her soul was used to create the bitto, he fought Ichigo, because the latter was attempting to protect his friend. Koga would have won, but Ichigo's inner hollow appeared, then Izuru Kira used his Zanpakutō's ability to bring Dalk to her knees. He is then forced to retreat.

After breaking through to the Soul Society, he helps Kariya and Maki Ichinose rally forces from the 79th District of Rukon. When Kariya adsorbs the Jōkaishō, he begins to wonder about his true motives. He then slams Kariya into a wall, and is stabbed through the stomach as punishment.

Going after Kariya, he is stopped by Tōshirō Hitsugaya. The two battle, and Hitsugaya appears to have the upper hand, being that metal is vulnerable to ice. However, after Dalk falls, Koga reveals her core is actually a large battle axe. The two continue, but he still fails to beat the captain and loses at his hand.

Yoruichi Shihōin finds and saves him, healing his wounds. Realizing he is the last of his kind, he apologizes for their actions and is free to go.

Powers & Abilities
Enhanced Strength: strong enough to pick up a metal girder and use it as a weapon with ease. Able to deal devastating blows to his opponents with minimal effort.

Master Hand-to-Hand Combatant: With his centuries of experience, Koga has become a highly proficient battler, enough to effortlessly dispatch several Shinigami unarmed.

Doll
is Koga's doll. When sealed she takes the form of a small metal marble. The marble multiplies and expands into a large metal sphere with the Bount seal. When unsealed the metal sphere explodes into a multitude of small metal spheres floating in the air, these spheres form together into a semi-humanoid shape, with a flirtatious female personality. Dalk has trouble with cold-based attacks, which make it difficult for her to split her body apart. As seen against Tōshirō Hitsugaya's Zanpakutō Hyōrinmaru. As a heavy, metal-based creature, she is also vulnerable to Izuru Kira's Zanpakutō, Wabisuke, which doubles the weight of anything it cuts. In contrast, Dalk seems to be nearly invulnerable to heat. In the Japanese version, Dalk is voiced by Takako Honda and in the English dub by Karen Strassman.


 * Metallic Body Control: In this form she can control the metal that makes up her body, reforming it into any shape she wishes. She is able to split herself into tiny spheres no bigger than a ball bearing, making it very difficult to destroy her. She uses a variety of attacks in combat, firing pieces of her body as projectiles, and even turning her arms into machine guns to fire makeshift bullets through. She is also able to absorb metal that she comes into contact with increasing the amount of metal she has.


 * Spider Form: After Koga drank the Bitto's soul elixir, Dalk became even more spider-like, retaining only her humanoid torso. She also gained much more metal to work with. She became faster, heavier and harder. In this form along with her average abilities she also can create strong webs made of the metal from her body, with the sticky consistency of an actual spider web. She uses the ability to entrap the opponent and limit their movements.


 * Battle Axe: Dalk's core form is a large battle axe that Koga wields. Due to his own immense size, wielding a weapon this large is no problem for Koga.
