Genma Shiranui

becomes the proctor during final rounds of the Chūnin Exams after the death of Hayate Gekkō. He usually has a senbon in his mouth.

Personality
Genma is shown to be very calm, collected, proud and "casual". He is never seen being boisterous or lost in difficult situations; he hates Orochimaru for power - playing.

Chūnin Exams arc
After Hayate's death, Genma referees the final round matches of the Chūnin Exams. He battles Baki during Orochimaru's attempted invasion of Konoha. However, their fight is interrupted when Orochimaru calls off the invasion. He also advises Sasuke to chase after Gaara telling him do what you must do for Konoha.

Search for Tsunade arc
Later, in the anime, he and Aoba are assigned to announce Tsunade's inauguration as the Fifth Hokage.

Sasuke Retrieval arc
Genma is returning to the village from a mission with Raido Namiashi, Iwashi Tatami and Shizune, when he and Raidou encounter the Sound Four. In order to defeat Raido and Genma, the Sound Four activate level two of their cursed seals, leaving Genma gravely injured and in serious need of medical attention. In addition to this, Genma and Raido barely had any chakra left.

Fire Temple arc
In the anime, he is seen giving out orders to some Chūnin during Furido's attack on the village.

Invasion of Pain arc
Later, Genma appears with Yamato and other Jōnin helping to restore the village after Pain and Naruto's fight.

Abilities
Genma is known for having been on difficult missions and participation in handful fights. Still, Genma has never been seen in combat. He can spit the senbon from his mouth as a projectile with enough force to deflect a kunai. Given that the Sound Four decided to activate their cursed seals in order to defeat Genma and Raido Namiashi, it is likely that he is a formidable fighter. After the fight, while the Sound Four were resting, they noted that they wouldn't have won without using their cursed seals.
