Akatsuki literally translates to Dawn or Daybreak.
Do you mean the akatsuki?
SPOILER ALERT Depends on what you are asking. His partner in the Akatsuki is Kisame Hoshigaki. I assume that is what you mean.
If you mean what akatsuki members were resurected in the manga, then its Nagato, kakuzu, sasori, deidara, itachi, and a 6th unknown person.
If you mean the strongest, probably Nagato or Tobi.
The akatsuki aren't kinda mean... they just have a goal. That goal is to put all of the Hidden Villages and small towns into a all-out war. The Leader of akatsuki plans to capture all the Jinchuriki and make them into the Ulimate Weapon. The Leader just wants to teach everyone true Pain. Akatsuki people just kill people because people get in the way.
If your asking about the founder of Akatsuki, then it is Madara Uchiha. (Tobi)
Daybreak in/of the east, twilight in/of the west.
no the akatsuki is hunting him instead...
Akatsuki Kambayashi has written: 'Kambayashi Akatsuki' 'Shuiro no tamago'
He died because he fight against the akatsuki, the leader of the akatsuki. Pain, he is the leader of the akatsuki, Master jiraya was killed by the akatsuki.
No, he never joined Akatsuki. Akatsuki wanted to extract Shikaku (One tailed Raccon) from him which results death but they did it. So there is no way he would join Akatsuki.
