Naruto is naturally impetuous and tends to rush into combat without thinking, and is very hyperactive. However, he is capable of devising some quite clever Jutsus when necessary. Naruto is the sealed nine-tails demon fox, and when he is under great stress or when his friends are severely threatened it starts to become unsealed

He initially hated Sasuke (he still hates him, but respects him too) and has a crush on Sakura, who hates him. Naruto also likes Ramen. A lot. In fact, Kakashi, his sensei, once thought that Ramen and being Hokage were the only things he thinks about.

A Genin level Ninja, he is a TaiJutsu specialist. Incapable of using NinJutsu or GenJutsu, he spent all his time and concentration on TaiJutsu. It is because of this determination and hard working ethic that Lee has become an outstanding Ninja. When in heated battle, Lee removes the extremely heavy weights he wears on his legs. This vastly increases his already amazing speed. His greatest technique being the Lotus, which, after using opening the bodies Initial Gate, he can perform the Initial Lotus. This Jutsu is self damaging, making it (in most cases) an all or nothing move. A forbidden technique, all of that high speed TaiJutsu puts a lot of stress on the legs and body, leaving the user feeling so much pain they can barely move. Although Lee is not your regular case. This is Lee's Trump card, and he uses it to only protect precious people, or to prove his Ninja way: to be a great Ninja, without using Ninjutsu or GenJutsu. After using it for the first time against Gaara, Lee's body was so beaten up that he could barely even move, and, after his left leg and left arm were both completely pulverised, and he was unconscious, he still strived to achieve his Ninja way. However, because of all of the damage that was done to his body during the battle, he was told by the Leaf Village medics that he would be unable to live as a Ninja any more, but after he had healed sufficiently, he was back on his strict training regime, pushing his body to new limits.

Hatake Kakashi, also known as 'the Copy Ninja Sharingan Kakashi', he is a Jounin assigned to look after and train Sakura, Sasuke, and Naruto. Kakashi has memorized over 1000 Jutsus (probably more), all of which are very impressive. He learnt them through a special eye technique which can copy Jutsus called the Sharingan - also known as the 'copy wheel eye'. However, because he is not a member of the Uchiha clan, it seems to have been attached in an operation - there is a scar over it, and normally the Sharingan effects both eyes, not just one. Kakashi is a very powerful Ninja, one not to be underestimated. He is known around the world for his incredible powers. He is rivals with Gai, a fellow Jounin in the Leaf village. They have fought almost 100 times, 50 wins and 49 losses. Gai claims to be stronger but we'll have to see about that...

A Jounin level ninja, he is the sensei of Neji, Tenten, and Rock Lee. Gai and Lee have a special connection, Lee idolizes and mimics Gai, and Gai has the utmost respect and admiration for Lee. A very talented Jounin, he has very dangerous Jutsu which he has passed on to his students, then forbidding those capable of performing them to do so unless it is to "protect a precious person". Gai is also described to be the "Eternal Rival" of Kakashi, and they have a record of 50 wins and 49 losses. Gai claims to be stronger but it is unknown which Ninja has had the most wins.

A Genin level ninja, she is a subordinate to Gai. Not much is known about her techniques, other than that she uses dozens of various types of weapons in battle, and she can throw them faster than the eye can see...

A Genin/Chuunin level ninja, he was the #1 rookie of his Ninja Academy graduating class. He was also considered to be the strongest and most talented of all the Genin. A member of the Hyuga Clan, branch house, Neji can never be leader of his clan. Using the Hyuga Style TaiJutsu, the strongest Leaf Village TaiJutsu style, combined with the Byukugan Neji is quit dangerous. With this style even a slight touch is enough to cause drastic internal damage. This TaiJutsu which has been passed down each generation is what makes the Hyuga so talented. Neji has a complete defense, having mastered the Juken (Gentle Fist Style), he is able to expel Chakra from his whole body and is able to defeat the physical attack with the force of his Chakra discharge alone. Making his body spin like a top, he dodges and pushes them back with their own force. Also making it a great offense. This is a secret Jutsu that is only passed down onto the successor of the Main Hyuga House, Neji is a genius among genius' to have mastered it on his own.

Sakura has a crush on Sasuke, but she may well have some competition. She's often self-conscious about her forehead, despite the fact that, if you compare it to the foreheads of some of the other characters, it's not that big at all. In fact, a heck of a lot of the male characters have a crush on her (for example Naruto (who she hates) and Rock Lee (who she's starting to respect)). At the start of the manga, all she seems to care about is love. However, during the Chuunin exam, her personality changes suddenly - she realizes that in her infatuation with Sasuke, she has neglected her duties as a team member - this coincides with her chopping off most of her hair (which she grew long because Sasuke apparently likes long hair). Then, she kicks sound-nin butt using her intelligence which is her main strength.

A Genin level ninja, she is described as a very talented female shinobi by her Sensei. Ino has the ability to take over peoples bodies using a Jutsu called ShinTenShin. Entering her spirit into her target's mind, Ino can take full control of their body for a few minutes.

A Genin level ninja, he is in Asuma's Team 10. Capable of using a Jutsu unique to the Akimichi Clan, Choji can increase the size of one part or even all of his body. This technique is called "Multi-Size no Jutsu", and when combined with "Leaf Style TaiJutsu; Meat Tank" it is quit formidable. Although it uses up a high amount of calories, and (when combined with "Meat Tank") will leave you very dizzied. By using "Meat tank" with "Multi-size", he can transform into a large ball shape and roll towards his opponent with furious speed and even bounce into the air. Sensitive about his weight, it may be dangerous to insult him about his size.

A Genin level ninja, she is in Kurenai's team 8. A Member of the Hyuga ichizoku(clan), main house, her father is the leader of the clan. As a member of the clan, she can use the Byukugan. Although a talented ninja, Hinata lacks confidence in herself, which is her greatest weakness. Having entered the Chuunin Selection Exam to change herself, Hinata has decided to stop running away from confrontation. Using the Hyuga Style TaiJutsu, the strongest Leaf Village TaiJutsu style, combined with the Byukugan eye technique, Hinata is quite a dangerous ninja. With this style even a slight touch is enough to cause drastic internal damage. This TaiJutsu which has been passed down each generation is what makes the Hyuga so talented.

A Genin/Chuunin level ninja, he is in Asuma's Team 10. He's the kind of guy who likes to spend his time just sitting around and taking his time with everything. He likes stuff that old men usually are into. So, he really likes Shogi (Chess) and Go. He's great with coming up with a strategy and Asuma has never beaten him once. Shikamaru would be a genius military leader according to Asuma. Although his grades from the Academy were almost as low as Naruto's. He felt that even moving his pencil in class was a pain in the ass and he always slept through tests. But Asuma had his doubts after seeing his skill at strategy games, so he gave him an IQ test once. The results, Shikamaru is a genius. His score was over 200. By connecting his shadow with his opponents, Shikamaru can control their movements. His best Jutsu is the Shadow Copy Skill (Kagemane no Jutsu), its only drawback is that there is a time limit (about 5 minutes) on how long it can be used. The ways in which he uses his Shadow Copy are quite ingenius, being able to stretch and manipulate the shape of the shadow.
