Gaara is a character from the anime Naruto. He has an older brother Kankuro and an older sister Temari.
Gaara has the sand demon Shukaku sealed within him, Prior to Gaara's birth, his father, then leader of the ninja village of Sunagakure, was forced to cut military spending and channel its revenue to other programs. To keep the village's military forces from becoming too weak, his father had the One-Tailed Shukaku sealed within Gaara during his birth; in doing so, his father hoped that Gaara would become the village's weapon, singlehandedly filling the void created by the budget cuts.
To help Gaara gain control over the powers granted to him by Shukaku, Gaara's father trained him in the ninja arts throughout his childhood. Despite years of efforts to tame and control the beast within him, Gaara was never able to gain complete control over Shukaku. Against Gaara's will, Shukaku would lash out and attack those close to him, making him feared as a monster by the villagers, despite his attempts to apologize. His father, fearing that Gaara might someday bring about the destruction of the village, ordered Gaara's assassination. Over the coming years Shukaku would protect Gaara from every assassination attempt and promptly kill the perpetrator. Realizing that he had been abandoned by his own family, Gaara adopted the belief that he, and by extension Shukaku, were the only people he could rely on in the world.
After Gaara fights Naruto, he realises the true meanings of love and friendship. Gaara and Naruto later become allies and help each other through out the rest of the series.
