Ami (亜美) was an Academy Student from Konohagakure. She appears during a flashback to Ino Yamanaka and Sakura Haruno's time in the Ninja Academy. During a kunoichi lesson she taunts Sakura about her forehead, prompting Ino to throw a flower (that she claims is poisonous) into Ami's open mouth. Ami quickly runs away to tell their teacher, Suzume. She has purple hair in a style similar to that of Karin. (Source: Narutopedia)
Shiore is a Genin from Kusagakure. He and the rest of Team Shiore are killed and impersonated by Orochimaru before the Chūnin Exams. Izumo Kamizuki, Kotetsu Hagane, and Mozuku eventually found their faceless bodies, alerting Anko Mitarashi. (Source: Narutopedia)
Age: 14 (I) Birthday: June 12 Blood type: A Height: 156 cm (I) Weight: 48 kg (I) Dosu is a genin from the Sound Village, and leader of his squad. They were under the direct supervision of Orochimaru during the chunin exams. Dosu uses a sound amplifying device on his left arm, called a melody arm, to increase the vibrations he makes when he hits something, causing damage to the opponents ears and messes up their sense of balance. He is the only member of his squad to advance to the second stage in the chunin exams after defeating Choji Akimichi. He showed dedication to Orochimaru's task of killing Sasuke Uchiha, but later became disillusioned after learning that Orochimaru had given Sasuke a cursed seal. Realising that he and his team were actually pawns used to determine Sasuke's worth, Dosu's outlook changed as he lost any and all loyalty towards Orochimaru and vowed to kill Sasuke for the purpose of undermining Orochimaru. Because of this, he would attempt to take down Gaara prior to the actual match to lessen the obstacles beforehand, a rather rash decision that cost Dosu his life. (Source: Naruto Wikia)
Uruchi Uchiha (��� ウル�, Uchiha Uruchi) was the wife of Teyaki Uchiha, and used to own a small bakery at the Uchiha compound in Konoha. She used to be one of the many people in the Uchiha clan who encouraged Sasuke to be like his big brother, Itachi. In a short conversation with Sasuke, she does not seem to pay attention to him, not knowing how old he was. She was eventually killed by Itachi (as well as the rest of the Uchiha clan; except for Sasuke who he left alive). Sasuke referred to her as an aunt, and called the man who interrupted in their conversation to save Sasuke from answering, uncle. (Source: Narutopedia) Since she is from the Uchiha clan, she should posses the Sharingan. But this is unknown as she is not using it or mentioned using it.
