Gaara

Gaara is the son of the Fourth Kazekage, and the younger brother of Temari and Kankuro. Before Gaara's birth, his father ordered Chiyo to seal the One-Tailed Shukaku within him, in hopes that Gaara would become the ultimate weapon for Suna. Because a sacrifice was needed, Gaara's mother, Karura, was used. Before she died, Karura cursed Sunagakure, hoping Gaara would avenge her death. Gaara was trained by his father, but raised mainly by his maternal uncle, Yashamara.Because of the power of Shukaku, the villagers of Suna hated and feared Gaara, seeing him only for the monster sealed within him. For a time, Yashamaru seemed to be the only person who cared about Gaara. When Gaara would mistakenly harm others due to the subconscious abilities granted to him by Shukaku, Yashamaru would be the only one who understood that Gaara hadn't intended to harm anyone. Gaara's father, however, did not see Gaara in the same light, and viewed Gaara's frequent attacks upon villagers as a result of a failed experiment that was a threat to Suna.Because of the danger Gaara imposed, his father began sending assassins to kill him, though when all attempts were met with failure, the Kazekage requested Yashamaru to kill Gaara. As a result, Yashamaru tried to assassinate Gaara, only to fail just as those before him. Gaara dealt a lethal blow to him. But when Gaara realized that it was Yashamaru, he was horrified, and screamed, before bursting into tears. Although Gaara tried to dismiss Yashamaru's attack as an order of the Kazekage, Yashamaru corrected him, by saying that he had willingly accepted the mission. Having never truly loved Gaara, Yashamaru hoped that killing Gaara would avenge the death of his sister, who had named Gaara after the phrase "a self-loving carnage" (我を愛する修羅, Ware wo ai suru shura), a sign of her intense hatred for Suna, not as love for her son. In the last ditch effort to kill Gaara, Yashamaru detonated a number of exploding tags covering his body, asking Gaara to "please die". Using his sand, Gaara survived the blast, and lost the only person he thought had cared for him. Since this incident, Gaara became an aloof and cruel person who would kill anyone to prove his existence and to obtain recognition from the village.
