The Birth of a Demon
Bore Gaara was born, a continuing series of budget cuts plagued the Land of Wind. This resulted in his father (The Fourth Kazekage) sealing the one-tailed beast, Shukaku, inside of him, making him a jinchūriki like Naruto.
The sacrifice that was made to seal Shukaku was in fact Gaara's mother.For years, Gaara's uncle Yashamaru told him of how his mother, Karura, loved him to the moment she died, when, in reality, she had cursed the Village Hidden in the Sand for her death. She gave her last child a name. His name was "Gaara", meaning "A self loving carnage", thus saying that Gaara was a demon that only loved himself, fought for himself, and thought only of himself. In reality, Gaara only tried to help others as a child, and, much like Naruto, he was shunned, simply because of his powers and jinchūriki status.
On one Occasion he tried to get a group of little kids ball for them, but rather than take it, they just left in terror.  The rush and Gaara's want for them to take it back and keep playing caused him to accidentally use his sand to hold them to the ground, nearly crushing them.  His uncle Yashamaru, one of the Sand's medical Ninja, realized what was happening and rushed to stop Gaara. In the midst of all this, Yashamaru received a minor cut on his finger and a wound to his forehead. Later that day, at home, Gaara is seen with a knife trying to slit his wrists.  Yashamaru walks in on Gaara just as he does it, but is relieved to see that the sands of Shukaku stop the knife blade. He then tells Gaara that it pains him to see that kind of thing, even if the sands stop him from receiving harm. Gaara then asks what pain is like, and Yashamaru explains that it is an unbearable experience, much like what he feels when he is left out from everything that the other children do.
He then explains that there are wounds that even he can't heal, and that these are wounds to the heart. Yashamaru explains that the only known cure to these wounds is love. He tells his opinions on Gaara's mother, how he thinks that every grain of sand is a symbol of her love for him. In reality, this was not so, because she cursed him as she died. Gaara then decides to show his newfound cure to the kids he accidentally harmed at the park earlier by giving them some wound ointment that his uncle gave him. When the door opened, the kid saw him and told him he was a monster and to get away from him. A disheartened Gaara trudged home silently until he wandered into a drunk. The drunk then told him to watch out and began threatening him... until realizing that this boy was in fact the jinchūriki. It was at this point that Gaara finally snapped. In a rage, Shukaku's sands wrapped around the middle-aged man, crushing him(since Gaara was still a child, the man's body was still in a recognizable form, as Gaara wasn't strong enough to crush them into a pulp until he was older). He continues his walk home, without any guilt on his face. His father sees him on his way home and they exchange glances. This would be the last even slightly friendly meeting between the two. As Gaara finally reaches the top of the building to his Apartment, a masked man began hurling his levitating kunai at the little Gaara. "Why... why... is it always ME?!" Gaara exclaims as the kunai dropped from the sand and wrapped around the masked assassin. Gaara's fist closed on the man as did the sand, with bone-crushing force. Gaara then calmed down and went from his state of rage to nervousness as he noticed a bandage on the mans finger. He lifted up the mask to find that the assaulter was none other than the only person that Gaara thought had ever loved him, his dear uncle, Yashamaru. "Yashamaru? But... why?" asked the confused child, in a broken, sobbing voice.
"Because, Gaara... I was ordered to." replied his half-dead uncle.
"By who?" said the broken six- year old, already in tears.
"Your father..." he said in an emotionless voice.
"Oh..." he said, lightening up, barely. "So that means that... you had no choice, right?"
"No, Gaara, you're wrong, I did have a choice." replied Yashamaru.
"I said that I loved you.. but, deep down inside, I hated you, Gaara. I could never forgive you for taking my sister away from me. Your name, do you know what it means? 'Gaara' a demon that loves only itself, and fights for only itself. That is the name she gave you. Your mother... she hated you... as do I. Now, please, think about someone else, for once, you monster, and, please die."
Yashamaru then opened up his Shinobi vest to release the multiple paper bombs that he had concealed on himself the whole fight, and killed himself in the explosion.
Gaara lay on his knees, angered, broken, and let out a scream that could have been heard throughout the Sand village, as the grains of Shukaku's sand all flew into one spot on Gaara's forehead above his left eye forming the kanji 愛(Ai)-love.
After a few years, Gaara's father, the Fourth Kazekage, decided that the assassinations attempts should stop, and that Gaara could be a very useful tool for the sand village.
The Chunin Exams
His first mission (as the Sand village weapon) was to enter the Chūnin Exams with his brother and sister, Kankurō and Temari, while secretly helping Orochimaru in his plot to take the Leaf village. During the first test of the Chūnin exams (a written test) Gaara used his third eye (a floating ball of sand) to cheat on another student's paper in order to get his answers.
During the second exam (the Forest of Death) it is shown that his team was able to obtain their two scrolls with great ease and that because of Gaara's bloodlust, ended up killing more people than they had to, even though Kankurō was against it.
Once they had reached the center tower,
Anko noted that it was extremely unusual that Gaara and his team had made it through the whole Forest of Death without so much as a scrape or cut.
During the Final exam preliminaries Gaara is pitted up against Rock Lee. Due to Lee's amazing Taijutsu strength and speed, he was able to break through Gaara's Sand shield and eventually move so fast that Gaara couldn't even see him.
Though things were in Lee's favor, Gaara was still able to win the battle because Lee was forced to use a move that could potentially kill him. Gaara ended up crushing Lee's left arm and leg, and attempting to kill him, which would have worked if Might Guy hadn't stopped the sand from hitting him.
The night that the Chūnin exams preliminaries were concluded, a sound ninja, Dosu Kinuta, approaches Gaara with intent to kill. "Do you ever sleep?" asks Dosu Kinuta. "No", replies Gaara "For fear of the demon inside of me being allowed to eat away at my personality even more...". Dosu Kinuta then explains that, since he'd seen Gaara's ability already in the Chūnin preliminaries (and that he'd be fighting him in the first round) that he'd attempt to just kill him in his sleep. After brandishing his weapon, Gaara killed Dosu Kinuta without second-thought.
Gaara later tries to kill Lee in the hospital, only to be postponed by Naruto and Shikamaru, the only thing keeping Gaara from killing both of them was Shikamaru's Shadow possession jutsu. He then reveals a small bit of his past and his views on friends and family to pass the time while Shikamaru slowly loses chakra. Gaara reveals that he has a monster inside of him, and that made Naruto both nervous and scared of Gaara.
When Shikamaru's jutsu loses effect, Gaara then tries to kill them both, only to be stopped by Might Guy, yet again. Guy tells him to save his energy for the finals, and everyone leaves. But before Gaara leaves he says, "If you ever get in my way again. I'll kill you."
After the month-long wait for the Chūnin exams finals, the contenders gathered for the fight. Due to the fact that Dosu Kinuta was not there, Gaara was paired up with Sasuke instead, who was also a no-show until right before they announced him a no-show.
Before the Final rounds Sasuke would have all too easily been defeated by Gaara.
But, with his new-found speed and strength, along with his powerful new jutsu-Chidori (lightning blade), he was able to put up a very good fight against Gaara, even able to give Gaara a very bad injury near his left shoulder. He freaks out because he bled for the first time.
After a while, Gaara gave into the demon inside of him, and his brother and sister had to take him into the Forest of Death, only to be chased down by Sasuke, and eventually Naruto, Sakura, and Kakashi's tracker dog, Pakun. Sasuke was defeated by Gaara's half demon form before Naruto could reach them. Gaara's attempt to kill Sasuke was stopped by Sakura, who stood in front of Sasuke with a kunai. This gave Gaara painful memories of his Uncle Yashamaru and Guy. He pushed Sakura aside, sealing her onto the side of a tree with constricting sand that grew tighter as time passed, giving Naruto even more reason to fight his best.
Naruto started off with a barrage of all of his shadow-clones until Gaara used his sand shuriken technique. Eventually, Gaara used his play-possum jutsu, allowing him to summon the full sized Shukaku demon, that planned to get rid of Naruto quickly with a sabaku-kyu attack. The only thing that saved Naruto was his last minute breakthrough with the demon foxes chakra, allowing him to summon the chief toad Gama-Bunta.
The battle escalated into a large scale fight with massive "bullet" attacks from both of the large fighters. Naruto used a transformation jutsu to turn Gama-Bunta into the Demon fox, which allowed for the chief toad to grab a hold of Shukaku, leaving the sleeping Gaara wide open for Naruto's attack, waking him up and releasing the seal of Shukaku's complete possession.
Naruto then rushes straight at Gaara, only to be surrounded by sand just as he gets within striking range. Seeing no other way, Naruto headbutts Gaara with all of his strength, and, seeing as both were all out of chakra, caused both huge fighting entities (Gama-Bunta and Shukaku) to disappear, thus sending both fighters colliding into the trees. Both warriors then leaped at each other for the final blow, with Naruto landing his punch straight into Gaara's face. The two shinobi both fell onto the ground, as Sasuke catches the unconscious Sakura in mid-air. Naruto then tries to talk to Gaara and ask him why he acts the way he does.
Gaara yells at him and tells him not to come any closer, but Naruto did not heed his words and continues to crawl forward inch by inch with only his chin. Naruto then tells Gaara how much alike they really are, and how he made it out of the darkness.
Gaara's siblings then come to rescue him, and, to their surprise, he tells them that he is sorry for what he'd done and then proceeds to ask them for forgiveness. Kankurō and Temari tell him that they would, and that it was fine.
Gaara's next appearance is during the battle against Kimimaro. He appears right at the last second to save Lee.
The fight then proceeds, with both warriors being put to their limits. The final blow would've killed Gaara and Lee if it weren't for Kimimaro's lethal disease killing him right before his blow would've landed.
Two years later, Gaara is the Fifth Kazekage (Wind Shadow) of Sunagakure (Hidden Sand Village), and has finally gained complete control over the demon within him, The One-Tailed beast, Shukaku. And now, the Akatsuki are after the jinchūriki (the people that hold the demons within themselves), and apparently see Gaara as one of their first targets. Deidara and Sasori are the two members who go after the powerful warrior. Sasori uses a puppeteering jutsu to take over the mind of Yura, the head guard of Sunagakure.
After infiltrating the guard system around the city, Deidara went in over head on a clay bird that he formed. Gaara notices the bird flying high above them, and leaves his office.
Meanwhile, Deidara scouts over the village with his scoped left eye, and after finding the Kazekage's residence, lands on top of the building and prepares for a fight. However, Gaara was already there waiting for him.
"Whoa..." said Deidara, very surprised at the speed of the warriors arrival. "But how did you know, hmmmmmm?" he asked.
"There are no such birds...in this desert." Gaara replied, pointing at the huge avian behind them.
Gaara wasted no time in sending sand flying straight towards Deidara. Deidara leaped on his bird and flew high into the sky. Gaara leaped onto his sand and flew after him in pursuit with startling speed.
"Ho, that's quite useful...." Deidara complimented, but Gaara did not take any notice.
Gaara raised both of his arms over his head, as the entire desert raised itself behind him. Deidara was left to simply stare in awe as it surrounded Gaara in an unbreakable protective shield. And as it began to engulf him. He barely had a way out at all, and still had his arm snagged, and then crushed with unimaginable force. His options were growing thin, as Gaara stared at him with his cold, expressionless face.
"Grrr..... I'm tire of your expressionless face! I'm going to wipe that look off of it forever!!!" Deidara said, obviously infuriated that Gaara had just ripped his arm off. The kazekage just stared at him blankly through the small hole that was in his shield.
He was very open in his attempts to kill Deidara, and sent the sand flying at him every second or so, and refused to give Deidara a second's rest.
However, Deidara had a plan, and it would require that Gaara choose between himself and the village. It was then that Deidara sent some of his specialized clay birds to exploit Gaara's shield. The small birds were then inside of Gaara's shield, and rather than let the explosion impact the entire Village Hidden in Sand, he enclosed the explosive clay Avian's within his shield and took the full force of the blast in a valiant, noble act.
"Hmmmm....leave it to the Kazekage to take the sand himself and hold it up...when it would have been so much easier to dump it on 'em...heheheh" Deidara said as his huge clay bird clutched the fallen Kazekage in it's claws.
"Gaara...." Kankurō said with a sad expression on his face. He knew that his brother had saved the entire village, and he was proud.
Deidara and Sasori take Gaara to their hideout. Where Akatsuki begins the extraction of the Shukaku from Gaara. The extraction takes three days and three nights. The extraction is complete and Gaara dies from the Shukaku no longer residing within him. During his time of death, Sakura and Chiyo (one of the elder siblings of the Sand Village) take on Sasori which ends in Sasori's death. Naruto and Kakashi take on Deidara. And Team Guy takes on a fake Itachi and Kisame. After the battles are over, the rest of the sand ninja arrive. They decided that they were going to help their Kazekage, the one who protected them. Chiyo then decides to give the remainder of her chakra to Gaara in a forbidden jutsu that brings back the dead. When she didn't have enough Naruto lent her some of his to finish the jutsu. After the jutsu was complete Chiyo died. She traded her life, for Gaara's. When Gaara awoke, he found out once and for all, that he is not alone in this world, and that many people really care about him.
When Naruto and the others left, Gaara showed that he still has the ability to control sand, but to what extent is still unknown as he hasn't appeared in the series since.
Gaara returns in Shippūden, getting ready to set off to the meeting of the five Kages. With his siblings, Temari and Kankuro as his bodyguards.
Sasuke Uchiha and Gaara have switched roles. Sasuke being one of the protagonist and Gaara being one of the antagonist. After a while Sasuke became an Antagonist and Gaara becomes one of the Protagonist.
In the land of Iron, at the Five Kage summit, Gaara and the other Five Kages were deliberating on what to do about the Akatsuki now that they have almost all of the tailed beasts. While this is happening, Sasuke, along with team Taka, infiltrates the Land of Iron. A white Zetsu comes in and interrupts the summit by exposing Sasuke and his team to the Kages. The Raikage flies into a rage and goes after him. By the time Gaara gets to the scene, the Raikage was already preparing to finish off Sasuke. He then used his sand to stop this from happening so that he could speak with Sasuke. The Latter rejects everything that Gaara has to say and then proceeds to use Amaterasu on him, only for his ultimate defense to block it. Then Sasuke causes the area they're in to cave in, making Gaara to cover himself, Kankurō, Temari, and Darui with sand.
By the time he gets back to the meeting room, Tobi is there with Sasuke in hand, explaining his plan to them. In light of this declaration of war, he and the other Kages band together to form the first Allied Shinobi Forces.
Powers and Abilities
Gaara has the power to control sand. He can summon it anytime he wants and it well does so. He can summon a lot of sand, enough sand to shield or cover a person. If anytime Gaara runs out of sand he can break down the ground to have lots more sand. He can control dry sand, if he uses regular sand it makes him tire very easily because it takes more chakra. That’s why he always keeps a calabash looking gourd with him, that’s from the sand on the back of him. The sand is already combined with Gaara's chakra; it makes it faster and stronger because it is easier to control.
When Gaara fights, he is very slow and he is always in one spot, he hardly even uses taijutsu. One of his first moves he learned was the Desert Coffin. Gaara uses the sand to cover the rival's whole body then drowns the rival in it making the rival suffocate. After this blow he does a move called Sand Burial then forcefully crushes the rival very hard into the ground.
Another time in battle if the rival was to ever attack Gaara and uses the sand to block every attack. Unless the rival has great speed and is too fast for the sand to block then he will get hit, just like in the third chūnin exam when Rock Lee was fighting Gaara he was fast to get an hit but Gaara's sand was too strong. Gaara can put a forcefield made of sand around himself to protect himself.
Gaara can also make sand replicas of himself called Sand Clone. Gaara can use this clone for distraction and battle. He can also summon sand for making himself a platform for flying; he can also summon a sand eyeball for spying.
He also has a demon inside of him called Shukaku, making himself have more power. Shukaku takes over Gaara's body more and more when after the transformation for it. But, he grows more and more destructive as it grows. With the demon he obtains more powers. He can now use "Sand Shurikan" and throw shurikans made out of sand. "Wind Style: Sandstorm Devastation" is another jutsu he obtains. He can throw up sand everywhere which is dangerous to the rival and the land.
Gaara can summon him any time he wants if he uses the jutsu called "Play Possum Jutsu". It's a jutsu that makes Gaara to fall asleep giving Shukaku a chance to take over. When Gaara wakes up he gets control back over his body.
