Yoko Kurama
Yoko was once a legendary thief in Makai (the demon world). He is incredibly powerful and respected, if not outright feared, by nearly every demon alive. Hiei chose to form a partnership with him so that he would never have to face him... and that's saying something. As Yoko, Kurama is cold, calculating, and arrogant. He is a merciless fighter of unequalled skill. He can control and manipulate (as in alter or change) plants, including terrible demon plants and is incredibly fast. He is also cunning and intelligent. When he reverts to this form he seems to forget most of his experiences as a Shuichi. At the very least he chooses to ignore his human emotions, though he does appear to remain loyal to the commitments and attachments/relationships he formed in that state. He also seems to look down on his human self somewhat. Yoko is not entirely without feelings though, he had a partner named Koronue who he was very close to. Yoko has nearly overwhelming powers and incredible speed. He is also very athletic (especially in gymnastics).
