Shigekuni Yamamoto-Genryusai is the Captain of Soul Society's First Division, often referred to with the title of Captain General. General Yamamoto founded the shinigami academy about 2000 years before the story of Bleach began, and has used it to train many generations of Death Gods. Yamamoto was a teacher at this academy, and personally instructed Shunsui Kyoraku and Jushiro Ukitake, both of which would go on to become Captains of the Gotei 13 themselves. Yamamoto admits to being proud of Ukitake and Kyoraku and that when they first became Captains of Soul Society, he boasted about them as though they were his own sons.
During the Soul Society Arc, Yamamoto spends much of the time organizing the other twelve Captains rather than doing things personally, but when
Shunsui and Jushiro make the move to stop the execution of Rukia Kuchiki, their former teacher was the one to step up and face both of them on his own. Though appearing feeble and frail, he is perhaps the most powerful Captain of Soul Society, with exception to Aizen Sosuke.
At the end of the Arc, he has made peace with Ichigo and his companions, even allowing Orihime passage into Soul Society during her training with Rukia. He stays in contact with Captain Hitsugaya via a communication system set up in Orihime's house, and has his Shinigami fight alongside Ichigo and his companions, even seeking them out while they were still in school.
The embodiment of conviction, Yamamoto follows the laws and regultaions of Soul Society to the letter, and expects the same of others. He is not a man to tolerate insubordination, and is vocal with those who attempt to be such a way. He is wuick to anger in the face of possible betrayal, and appears rather ruthless in combat. When in a state of peace, he carries himself with an air of fragility, even to the point where he has fallen asleep standing while awaiting Shunsui Kyoraku's arrival for a meeting.
Yamamoto possesses a powerful Reiatsu, capable of paralyzing Lieutenant Nanao Ise with a simply look. This later caused her to faint, and she had to be taken a safe distance away from the Captain General simply to regain her ability to breathe. He is also seen to be experienced in the art of Shunpo, though is not quite as fast as Shunsui or Ukitake, possibly due to his age.
His Zanapkutou is the most ancient one in Soul Society, as well as being the most powerful fire type. Ryujin Jakka (Flowing Blade like Flame) is activated by the command "Bansho Issai Kaijin to Nase" (Reduce the whole of creation to smoldering ashes), at which point the blade of the sword is transformed into fire. The aura of this weapon can disintegrate anything that Yamamoto waves the sword at, changing it into nothing more than into ash and engulfing the surrounding landscape in flames. Kyoraku and Ukitake, both high level Captains, can resist instant death at the hands of this weapon, but are still being injured by it's presence.
