his abilities are ridiculously powerful and resourceful, for example the handseal that creates the avalanche of sand, capable of burying opponents alive and then creating a shockwave (sabaku taiso) to obliterate them.
His childhood was extremely sad, and made him very disturbed when he grew up. He has a bloodlust and kills anyone he can, when he can.
He is incredibly powerful and is feared by everyone in his village, when he was first intodruced in naruto, he was the most powerful genin and in the chunin exams, people feared going against him.
He has a demon sealed inside of him, that will take over him when he sleeps. So he is an insomniac.
He has dark lines around his eyes, making it look like he's wearing thick eyeliner. but its really from the demon shukaku.
His sea-green eyes are emotionless and they intimidate most people.
He is my favorite character in the show naruto, and he's uber sexy :P
Hes pretty hardcore because he controls sand and has a wicked tattoo on his head. Gaara likes to walk in the beach, destroying kids sand castles, just to build a giant mansion of sand to brag about it.
Kid: Hey! Look at my sand castle!
*Gaara kicks it*
Kid: Hey man wtf!
Gaara: I love to kill things.
Kid: Emo bitch! No one loves you! Kill yourself! I hate you! I HATE YOU!!!
Gaara: What... did... YOU SAY??????????
*gaara goes gaga*
Kid: HOLY SHIT!
Gaara: YOU DONT LIKE ME??? ARRGG! THE PAIN!!! DIE!!!!!
*gaara kills the kid by snapping every bone of him with his sand. Them he makes the body explode, leading to a bloody mess: gibs all over. Them he picks the kids heart, and smashes it with his hand, with blood and blue veins coming from all sides The carnage is unbelievable*
Gaara: I feel better :)
And thats a day in Gaara's life.
