Gaara of the Sand Sticker
Gaara is a shinobi of Sunagakure. He was made the jinchūriki of
the One-Tailed Shukaku before he was born, causing the villagers of Suna to fear him as a monster.
With nobody to connect to, he grew up hating the world and looking out only for himself,
giving his life meaning by killing anyone he came across. After being defeated by Naruto Uzumaki.
