How does madara die?

Answer 1

He gets taken down by Deidara and is brought to the Akatsuki's hide out where they extract his kyuubi.

He doesn't permanently die though because Chiyo uses a life transferring technique to bring him back to life in exchange for hers.

There is only one mistake I see in your answer. Gaara does not contain Kyuubi, Naruto does. There are different names for each bijuu. Ichibi, Niibi, Sanbi, Yonbi, Gobi, Rokubi, Shichibi, Hachibi, and Kyuubi. 1-9 in that order. Gaara contains Ichibi.

Gaara died by having his biiju taken out of him by Akatsuki after he was captured by Deidara. But he was brought back to life by elder chiyo (Sasori's grandma) in exchange for her own life but at the moment Gaara is still alive.

technically he doesn't- Deidara from Akatsuki capture him and they suck out his Jinkchuriki (One tailed Shukaku) and when they do that, you cannot survive that, so Gaara is left with no soul, only a shell. But Lady Chiyobaa Uses the Ultimate Medical Ninjutsu and Gives her life to him with the help of Naruto. Thus, Gaara is brought back to life, but no longer a Jinkchuriki.

Hope this helps you!- Narutofan2000
