Naruto's father-Namikaze Minato, the Yondaime Hokage (4th Hokage) of Konoha, sealed Kyuubi into Naruto when Kyuubi got pissed off by Uchiha Madara and attacked Konoha in his rage-remember, MADARA PROVOKED KYUUBI, so Madara kinda brought it upon the village to deal with the demon fox. Naruto was the newborn baby Kyuubi was sealed into. Minato was one of a few people who could use the attack that takes the soles of the evil, feeds it to a Shinigami (death god/god of death) which seals it in him, then it kills him too. The Sandaime (3rd) Hokage used the attack against Orochimaru-teme (snake @^$@^!&$) and temporarily prevents Orochimaru from destroying Konoha by taking his own life with that attack (sorry, I don't know the attack's name). It was the dying Minato's last wish that Naruto, his son, be seen as a hero, not just as the Kyuubi himself. Unfortunately the villagers don't see him as a hero...and you know the rest.
To protect the leaf village...Minato sealed the fox in naruto
Naruto has the nine tailed fox demon sealed inside of him. In later episodes, they usually refer to it as a chakra monster.
the kyuubi is the nine tailed demon fox yodaime sealed within Naruto.
The one on his stomach was the seal used to imbue the Nine-tailed Fox demon inside him. It is a Reaper Death seal. This is a jutsu that his father, the Fourth Hokage, used to take away some of the fox's power by sealing it within Naruto.
Naruto is NOT Kyuubi! Get this into your head! He and the demon fox are ENTIRELY different! The villagers know that the fox is sealed into Naruto but they treat him as an outcast, not the hero keeping Kyuubi from getting his revenge on Konohagakure no Sato (Leaf Village)
No, the 4th hokage/Naruto's dad, SEALED the demon in Naruto which kills him,that's why Naruto was so lonley anywho, it's physical body is gone, but it spirit still rages on(inside of Naruto).
Naruto is treated diffrently because his father sealed the 9-tailed fox demon Kyuubi inside of him when he was an infant.The reason why is unknown.

It almost did when Naruto was in 8 tailed form while fighting with God Realm Pain. Naruto ,while in 8 tailed form was uncounciusly talking with the Demon Fox. The Demon Fox persuade naruto on taking off the seal and Naruto almost take it off, that's when his father, the 4th Hokage appear as a memory and pull naruto away from the Demon Fox and tell naruto that he is his father and tell him stuff about the time when the Demon Fox attack Konoha. For more info read Naruto manga chapter 440 - 441.
