Genma Shiranui

is a Tokubetsu Jonin. He always has a senbon needle in his mouth to use as a weapon.

Chunin Exams
During the Chunin Exams, Hayate Gekko (third proctor) was killed before the final rounds. Because of this Genma took over and was the proctor during the Chunin Exam finals. The Village Hidden in the Sand attacked Konoha with the help of the Sound Village (founded by Orochimaru). Having the battle interrupted, Baki (team leader of the Sand Genin, consists of Temari, Kankurou, and Gaara) goes head to head with Genma. During the battle he tells Sasuke to follow Gaara.

Search for Tsunade arc
After Tsunade accepts being he new Kage he is given (along with Aoba)the task to announce the inauguration of the fifth Hokage to the village.

Sasuke Retrieval
Later on in the series, Genma is on a mission with Shizune, Iwashi Tatami, and Raido Namiashi. After the mission was over, they began heading back to Konoha when they hear a loud noise. Genma and Raidou decided to check out what was going on. They meet with Sound Four (consisting of Sakon, Tayuya, Kidomaru, Jirobo). They begin to fight. Although as strong as Genma and Raidou are, they are still no match for the Sound Ninja during first state and second state of Orochimaru's cursed seal because they were low on chakra due to their previous mission. Later on, Shizune finds them and heals them. Genma states that their powers were well beyond any normal shinobi.

Fire Country
Genma reappeared in Part II in a filler arc. He along with other Konoha ninjas, were fighting against the zombies that Kazuma had resurrected. Genma happens to act as a leader of the Konoha ninjas as he is mostly seen giving out orders to them.
