He never sleeps. Gaara has chronic insomnia because he is afraid of Shukaku completely possesing him.
Gaara has black rings around his eyes because he has chronic insomnia. Gaara wont sleep because he is afraid of Shukaku (demon possessing Gaara) to completely take over him when hes asleep.
No. His jutsu keeps him awake in order to keep his biju under control. If he falls asleep the demon comes out. He has some kind of insomniac jutsu that help him keep awake, also theorized that it is partially the cause of his behavior. EDIT: Actually, it is suggested in the anime that he does sleep though does so rarily because any sustained amount of sleep will cause Shukaku to slowly eat his soul and take over control.
gaara
It is unknown. Sabaku no Gaara is his only name we know of. His surname isn't revealed. I don't think Gaara has another name besides Sabaku No Gaara but that's just my opinion. Yes, Gaara has no last name. Neither does Kankuro or Temari, seeing as they are brothers and sister. I do not believe TenTen has a last name either. Gaara only goes by Sabaku no Gaara, meaning Gaara of the Desert or Gaara of the Sand. Many people (now) call him Gaara-sama when he is Kazekage.
Ninjutsu: Gaara Taijutsu: same Genjutsu: gaara smartness: shikamaru speed: gaara stamina: gaara So basically Gaara would thrash shikamaru in a fight.
Gaara was created in 2000.
Temari is oldest, then Kankuro, then Gaara
I don't know.But i think she loves him(GAARA).It's because i can see her love for Gaara in her eyes.(cute ... Isn't it?)
Gaara died after having his Shikoku sucked out of him. After Naruto and the others retrived Gaara, Lady Chiyo then revived gaara. It is unknown if gaara still has the same skill as when he had the Shikoku. But it will soon be found out what his skills are after he is revived.
No, Gaara does not kill Temari.
She died after having Gaara-kun.
