A Genin/Chuunin level Ninja, Sasuke is the natural genius offspring of the powerful Uchiha Clan. The most outstanding Clan in Leaf Village, the Uchiha's advanced bloodline give them the ability of the Sharingan. This ability allows Sasuke to be able to perform other's Jutsu just by having once witnessed it in use, as well as the ability to anticipate what a person may do next, and see through GenJutsu among other things. Through the Sharingan, Sasuke has learned some of Rock Lee's powerful Taijutsu and who knows how many new technques he could have learned if he was allowed to watch the Chuunin exam third test preliminaries? Though Sasuke's talent is not only confined to the Sharingan, before this ability even awakened he was considered the #1 Academy Ninja and the #1 rookie Genin. It is becuase of these abilities that Orochimaru is interested in Sasuke and gave him a Curse Seal/Stigma. Receiving the small mark which appears on the neck through a bite from Orochimaru, afterwards the Sasuke falls unconscious. Then, strong enough to survive the 9/10 chance of immediate death, he regains concsiousness. Just by releasing Chakra the curse becomes active and forcibly pulls out more Chakra, stealing the persons mind. At this point the the small mark on the neck grows to wrap around Sasuke's whole body. It's a forbidden Jutsu which eats at the user's body. Sasuke's will power is surprisingly strong enough to hold back this curse and after Kakashi performs his Evil Sealing Method on him, it becomes even easier for him to control it and use his Chakra.

Uzamaki Naruto is the main character in the series. He 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, don't miss this, it's cool! He dreams of being acknowledged by everyone in the Leaf village. He is an outcast (nothing like being a demon to ruin your reputation). He has a close bond with Iruka, initially hates 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 once thought that Ramen and being Hokage were the only things he thinks about.
