Gaara

When Naruto and Gaara fought during the Konoha Crush and Naruto defeats Gaara, Gaara took this as proof that his own choices in life were wrong; he had surrendered to his difficult circumstances too easily. From that point onward he starts moving away from "Gaara of the Sand Waterfall" and started emulating Naruto instead, improving his relationships with his siblings, making friends within Suna and without, and finding something that he's willing to give his life to protect. His relationship with Shukaku did improve somewhat when he told the tailed beast he used to hate it, but was grateful to the beast because he was able to meet Naruto due to the painful life Shukaku made him endure. He also developed more sympathy for even enemies, as he pitied Kimimaro's emptiness and loneliness as a motivation to serve someone as evil as Orochimaru.Gaara becomes Suna's Kazekage by the start of Part II, signalling the success of his emulation of Naruto. As Kazekage, Gaara becomes much wiser than most people his age when he took on the role. He forgave his father for trying to assassinate him as he was only trying to protect the village. Gaara also gains a new purpose in life by dedicating all his energy towards serving the village and those who live there. Although he retained some detractors, most of the villagers adore him and will do what they can to help him reform Suna and the rest of the world. Even this reform is very much inspired by Naruto, as he wishes for the Five Kage and their hidden villages to cooperate and benefit from each other in the same way that he has benefited from Naruto's influence. Gaara believes in forgiving past differences and strife, abandoning antiquated concepts of "honour" that only promote isolation, and serving a purpose greater than one's self. As in Suna, this unity that Gaara advocates is slow to catch on, for a time only gaining support from Naruto's own Konohagakure. By the time of the Fourth Shinobi World War, however, the Five Kage are convinced by Gaara and this in turn starts trickling down into the larger Allied Shinobi Forces. Despite his history of cruelty and young age during his ascent to Kazekage, Gaara attains the love of his people by showcasing his idealism, compassion and willingness to reform himself. A man of few words, Gaara leads by example, an assertive, thoughtful and collected presence in the heat of diplomacy and battle, who willingly puts his life on the line for his friends and allies. Gaara's way with words, astuteness and integrity earn him the respect of the older, more experienced Kage. Gaara's touching speech before the Allied Shinobi Forces produces a resounding response and is able to mend the rift between the Five Great Shinobi Countries. Gaara's superlative leadership abilities lead to his posting as Regimental Commander of the Allied Shinobi Forces. Gaara has fair skin, green eyes, and short auburn hair. He lacks distinctive pupils or eyebrows, the latter of which others sometimes make fun of. He's had tanuki-like black rings around his eyes his whole life, which Gamabunta attributes to insomnia. As a child, he carved the kanji for "love" (愛, ai) on the left side of his forehead, which his hair is parted in order for it to be kept visible. In Part II, many girls in Sunagakure start to consider Gaara handsome.In Part II, Gaara wore a long-sleeved crimson coat and full-length dark trousers with a pair. Over the coat he wore two buckled belts, a grey vest held in place by a single strap over his left shoulder, and two buckled belts which he also used to carry his gourd. Gaara speaks in a monotone voice, but when experiencing strong emotions, his voice and face will slightly change to accommodate those feelings

Gaara used to be the Jinchūriki of the one tails, Shukaku, but it was extracted from him by the Akatsuki not too long ago. Because of Shukaku, Gaara, all his life, suffered from insomnia, as he'd feared Shukaku would take over his body if he fell asleep. But now, with Shukaku gone and him no longer a Jinchūriki, his sleep schedule is improving. But not quick enough. So, while on a mission to the Hidden Leaf Village, Gaara collapses during the meeting with Lady Tsunade.
