Hideaki Kobayakawa

Hideaki Kobayakawa (小早川 秀秋) is considered to be Hideyoshi's nephew and is the famous turncoat at Sekigahara.

Samurai Warriors
In Samurai Warriors 2, he is a young and indecisive general at Sekigahara. He is stationed in a garrison and hesitates to take action. Ieyasu often orders his men to force him into action, such as ordering Magobei Fuse to fire at him or sending Hanzō Hattori to threaten him. If the Western Army prevent these from succeeding, he will finally charge for the Western Army. He is alternatively seen to have already defected at the start of battle. In Motochika's stage, he defects once more to the Western Army and is touched to see anyone come to his rescue.

In Nene's dream stage, he's one of her allies and defends the main camp. Though Ieyasu tries to break his will, he will be loyal to his aunt.

Kessen
Kobayakawa appears as a member of the Western Army in Kessen. He is relatively the same as his Samurai Warriors counterpart except that he acts frightened by the mere sight of his comrades. He came in contact with Ieyasu prior to the battle and promised to move out against his side immediately. However, he spends a majority of the battle contemplating and will refuse to take any action. If the Western Army does poorly, he will defect to the East and charge for Mitsunari's camp. Should the Western Army win, he remains a reluctant yet massive unit.
