He doesn't have a brother.
naruto does not have a brother
No Naruto has no siblings, he is an orphan with no blood relations, however he refers to Sasuke as his 'brother' which he means in more of an emotional way than literal.
yes he was separated from naruto as a kid but he doesn't recognize naruto
No. They are not even from the same country.
No! Sasuke only have (well... he HAD, now that he killed him) one brother, Itachi. Naruto does not even have a brother.
His older brother is Ukon.
Not according to the existing storyline. But it is not ruled out.
nagoto is naruto's older brother I guess >:S
Pein is a boy from the rain village HE IS NO WAY RELATED TO NARUTO
Naruto doesn't have an older brother he's an only child.
