Korobi

is a ninja from Sunagakure and a subordinate of Gaara along with his partner Yaoki.

Personality
He is shown to be cowardly and wimpy around Gaara, due to him formally being a murderous maniac. He later befriends Gaara, forming one of Gaara's very first friendships.

Konoha History Arc
When Konoha and Suna start to get along again, Korobi is assigned to a team with Gaara in order to take out a group of bandits located between Suna and Konoha, which Team 7 was also assigned to. He is very afraid of Gaara at the beginning, unable to forget what Gaara used to be like.

When Gaara is caught in a trap by Suna's assassination squad, he tells Korobi and Yaoki to get away. Naruto runs into them, learning that Gaara was captured and asks them why they abandoned their friend. Korobi and Yaoki both wonder if Gaara is their friend. Korobi and Yaoki both burst dramatically onto the scene, announcing that Gaara is their friend and they're sorry they left him. They then assist Naruto in rescuing Gaara. After their mission is finished, Gaara asks Korobi and Yaoki to repeat what they said and they happily say they're his friends.
