Deidara

Name: Deidara
From: Rock
Birthday: May 5
Age: 19
Blood type: AB
Height: 166cm
Weight: 50.8 kg
Affiliation: Akatsuki
Ring: 'Blue' in kanji
Ring Position: Right Index Finger
Partner: Sasori, then Tobi
Weapon: Clay bombs
Hobbies: Playing clay

Background: Deidara is the youngest member of Akatsuki Group and has great respect and passion for art. He is an S-class missing nin from Rock Village who left his town in pursue of greater opportunities to practice his art.

The Deal with him: His artistry takes form in his clay creation. He molds figures using the mouths on his palms then infuses it with chakra to become a destructive weapon called clay bombs. His clay handiwork varies from the tiniest piece to gigantic clay explosives, from animal figures to deceivingly real human clones. He can control them at will and even uses it for transportation. 

Deidara has an explosive personality as his clay bombs. His temper boils very quickly and he gets annoyed easily. Being trigger-happy that he is, you wouldn't want to risk making him angry, hmmm? 

He is a clever strategist and often uses his clay to deceive his opponents. He is assigned to capture the one-tailed shukaku along with his then partner, Sasori. He had an explosive battle with Kazekage Gaara that cost him his left arm. Later after Sasori died, he is teamed up with Tobi who annoyed him with the newbie's carefree personality. He believes Akatsuki members must be formidable and serious. 

Sai

Name: Sai 
Age: 17 
Birthday: 25 November 
Zodiac: Libra
Rank: Chunnin
From: Leaf
Team: Team Yamato
Teammates: Uzumaki Naruto, Haruno Sakura

Sai is known to be Sasuke's replacement. He does have to struggle with the title but he seems to be making a name for his own.

Another introverted ninja caused about the tragic loss of his brother. Sai is a gifted artist who has good eyes for details. A trait that is very useful to being a ninja. He is indeed observant and strategic in his mission. 

Though being almost emotionless helped him in accomplishing his missions, it did him bad in the long run. He cannot conceive the meaning of friendship and brotherhood. He's even bewildered on Naruto's initiative to rescue Sasuke.

His great talent for drawing (which by the way, would surely earn a praise from Deidara) is also the source of his jutsu. He can make his drawings come to life by infusing chakra on it, also called “Super Beasts Imitation Picture.” Aside from this, he's exceptionally skilled in hand-to-hand combat as well.

Kabuto Yakushi

Name: Yakushi Kabuto
Age: 19
Birthday: 29 February (celebrates birthday once every 4 years)
Zodiac: Pisces 
Rank: Genin
From: Leaf
Teacher: ??
Teammates: Akadou Yoroi, Tsurugu Misumi
Other Affiliates: Orochimaru
Most Used Technique: Running away from Kakashi 

Background: His origins were unknown. Years ago, during the ninja wars, the leader of the Konoha medical squad brought a boy back from the battlefield and adopted him.

The Deal with him: Kabuto is a traitor and spy of the Hidden Village of Sound and Orochimaru's right hand man. He pretends to be a Genin of the Leaf who failed the Chunnin exams 6 times in a row on purpose to gather data for Orochimaru. He is as strong as a jounin and is even said that his strength is comparable to Kakashi's.

Kankurou

Name: Kankurou 
Age: 15
Birthday: 15 May
Zodiac: Taurus
Rank: Jounin
From: Sand
Teacher: Baki
Teammates: Gaara, Temari
Family: Kazekage (Father), Temari and Gaara (younger siblings)
Weapon: Those weird puppets
Hobbies: Face painting.

Background: Son of former Kazekage and brother of current kazekage. 

The Deal with him: Kankurou is probably best known for walking around in his pajamas and carrying heavy looking puppets on his back. Kankurou uses branded puppet weapons created by Sasori of the Red Sand, former Sand nin and current Akatsuki member.

Though a formidable ninja in his own right, Kankurou's career is shadowed by his baby brother Gaara's achievements. When they were little genins, all everyone talked about was how scary Gaara was. Gaara's insane abilities as the Shukaku's carrier also made him the the leader of the team. When Gaara became Kazekage, all everyone gushed about was how much they love him, once again side-lining Kankurou until he got his ass kicked by Sasori of the Desert.

Kankurou's avid hobby with experimental face painting of various symbols and shapes is also really useful in distinguishing his age and timeline of events during the flashbacks in the anime.

Iruka Umino

Name: Umino Iruka
Age: 25
Birthday: 26 May 
Zodiac: Gemini 
Rank: Chuunin
From: Leaf
Occupation: Pre-Genin Teacher in the Ninja Academy
Most Seen: Eating ramen with Naruto

Background: Umino Iruka lost his parents during the invasion of the nine tailed demon fox

The Deal with him: Umino Iruka is one of the first to acknowledge Uzumaki Naruto. Iruka relates to Naruto as he himself lost his parents in a young age and grew up trying to vie for attention. initially failing Naruto in the Genin exams, Iruka later passed Naruto after the boy saved him from Mizuki (and celebrated over a bowl of ramen).

Umino Iruka has a mild kind hearted personality as docile as his name (which means dolphin), and is truly a new age sensitive ninja. He is also the first to be defeated by Naruto's devastating technique, the Sexy No Jutsu.

Anko Mitarashi

Name: Mitarashi Anko 
Age: 24 
Birthday: 24 October 
Zodiac: Scorpio 
Rank: Special Jounin 
From: Leaf
Teacher: Orochimaru 
Teammates: - 
Forbidden Technique: Dual Snake Destroyer 

Background: Former subordinate of Orochimaru.

The Deal with her: Not much is revealed about Anko yet. We first saw her during the Chuunin exams as the exuberant loud-mouthed examiner of the second exam. Her wide confident smiles were soon doused with the knowledge that her former teacher, Orochimaru had returned to the village. Orochimaru had used her years ago when she was his subordinate and had placed a cursed seal on her, which would have killed her had she been weaker. Anko is rash, impulsive, and very much haunted by her past affiliation with Orochimaru.
