they both have demons inside them called demon foxes gaara is i
think the 3 tails and nartos the kyuubi (9 tails)
<edit> actually gaara had the ichibi (one tail)
- i don't think its a fox... it doesnt even really look like a
fox. gaara has the shukaku. a one tailed thing. it doesnt really
look like an animal. and naruto have the 9 tailed fox in him. their
opposite jinchurikis. the shukaku is the weakest of the tailed
beasts and the kyuubi is the strongest of the tailed beasts.
naruto and gaara were both hated when they were kids. but naruto
made friends eventually. and gaara didnt have any friends. gaara
trusted only his uncle. but his uncle tries to kill him and the
shukaku or gaara kills him. many people tried to kill gaara. nobody
tried to kill naruto (when he was little i mean). gaara never made
friends. naruto did. even though naruto was the strongest
jinchuriki and gaara was the weakest jinchuriki, gaara was hated
way more than naruto. (guess because it was more obvious espacially
from his insomnia and he started killing people). even when gaara
apologized to a kid that the shukaku hurt, the kid still hated him.
even tamari and konkuro didnt like him until they become a team i
guess
