Gaara

Gaara is one of the main characters in Naruto. He was first introduced to be an enemy. He is the Jinchuriki of The One Tailed Shukaku

Past
Gaara is the son of the Fourth Kazekage and Karura. His siblings are Kankuro and Temari. Gaara's past is much like Naruto Uzumaki's past. He is a Jinchuriki so many people hated him. The Shukaku was sealed inside of him when he was being born.but in order to seal a tailed beast there must be a human sacrifice. The sacrifice in this case was Gaar's mother Karura. The Shukaku was sealed inside of him because his father the Fourth Kazekage ordered the village elder Chiyo to seal the Shukaku inside of Gaara. To make him the ultimate weapon. Later on Gaara's uncle Yashamaru raised him as a child. It seemed like only Yashamaru cared and loved Gaara much like how only Iruka Umino was the only one who cared for Naruto.

Because Gaara couldn't control the Shukaku's power yet he often hurt people by accident. Because of those incidents Gaara's father sent assassins to kill his son but none of them worked. Eventually Gaara's father sent Yashamaru to kill Gaara. When Yashamaru confronted Gaara Gaara immediatly struck him with a lethal blow. Then Gaara noticed it was Yashamaru he had killed he burst into tears and screamed horrified that he had just killed his only friend. After that Incident he eyched the word love on his forehead and became a cruel person who would have no mercy for any opponent.
