no i don't think gaara knows how to blush.
Pretty much; the only difference is that he no longer has the Shukaku. He can probably sleep now that the Shukaku is gone, but as far as i know that hasn't been specified.
No. At least not in anything that isn't filler. He might have when Lee tried to imitate Gai when he was giving Kakashi a piggyback on the way home from the Save Gaara arc.
No.
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 have a last name.
She died after having Gaara-kun.
