You have to finish Fragment or get alot of Storm Points
What I know is Danzo vs Sasuke FIRST!!!!!!then Sasuke vs Naruto on the end!!!!!!
you have to finish Fragment. Then you'll unlock Taka Sasuke(or Akatsuki Sasuke) and Killer Bee.
Karin healed Sasuke through him biting her arm and sucking her chakra while Taka was fighting Killer Bee.
Sasuke formed Taka in "Naruto: Shippuden" during Episode 152, titled "Somber News." After leaving Konoha, he recruits Suigetsu, Karin, and Jugo to assist him in his quest for vengeance against Itachi Uchiha. This new team is initially called "Hebi" but later rebranded as "Taka," meaning "hawk."
You can unlock Taka (Akatsuki) Sasuke in Naruto Ultimate Ninja Storm 2 when you have 560 000 SP. hope it helped!
After Sasuke finds out Naruto killed Pein(Nagato) and saved Konoha, he decides he is going to invade the Kage Summit and sets off with Taka.
I believe its during the get together of the new "Team Taka" (Team Hawk)
They started off there goal killing Itachi Uchihia, Danzo, Raikage, and almost Killer Bee. And Naruto and them started training to bring Sasuke back home.
Sort of, Suigetsu and jugo gets captured by samurai and Karin is almost killed by sasuke, then caught by team Kakashi. Suigetsu and Jugo later rejoins sasuke
He joins Orochimaru for 3 years for training. He then kills Orochimaru, and forms the Hebi (later known as Taka), which includes Jugo, Suigetsu, Karin, and himself. Taka then does some favores for the Akatsuki (specificlly Madara), like capturing the 8 Tails. They wore Akatsuki robes when doing so, but after the favor was done, Sasuke claims the Taka isn't working for them
Killerbee is still live. Sasuke's group Taka tried to take him but he escaped by taking a form of tenticle of his tailed beast.
sasuke's clan is called the uchiha clan. :) but then he creates a team called hebi, later known as taka. and he is also in the akatsuki :)
