Akatsuki is an organization consisting of rogue shinobi from all sorts of villages. Akatsuki's goal is to collect all the Bijuu, or Tailed-Beasts. The leader of Akatsuki is Pain, however Tobi (aka Uchiha Madara) is the actual shadow leader and mastermind.Madara reveals that he set up Akatsuki to collect all the Bijuu and revive the legendary Juubi (or Ten-Tails), which is a fusion of all 9 Bijuu. After becoming the Juubi's host, he will have enough power to preform Mugen Tsukuyomi which will cause a world-wide tsukiyomi.The Akatsuki members are:Sasori (dead, killed by Sakura and Granny Chiyo)Itachi Uchiha (dead, killed for revenge by Uchiha Sasuke,Itachi planned his death and let Sasuke kill him)Kisame (dead, killed by Gai in Kumogakure)Pain [Nagato] (dead, killed due to chakra overuse when reviving all of Konoha).Konan (dead, Madara killed her after she refuses to give him the location of Nagato's body after she leaves Akatsuki)Hidan (restrained, in pieces, underground and slowly dying)Kakuzu (dead, killed by Naruto and Kakashi)Deidara (dead, killed by Sasuke after using CO)ZetsuTobi [Uchiha Madara]Orochimaru (dead, Itachi killed him with Susano'o in his battle with Sasuke, thus stripping Sasuke of his curse mark)Kabuto later revives most members using Edo tensei (impure world resurrection) when he allies himself with Madara in preparation for the fourth ninja war.
He Got it From Obito when he was on a mission when he was younger. Obito got crushed by a rock and gave kakashi his Sharingan as a gift before he died. Obito had the Sharingan because he was an Uchiha.
Other than the bloodline Uchiha Sasuke and Uchiha Obito have no relation. Obito was born and died way before Sasuke was even born.
No, Kabuto is the one reviving the dead.
Itachi is dead.
TWO MEMBERS: Sasuke and Obito Uchiha are the last known living members of the Uchiha clan. Most known members, including Sasuke and Itachi's parents, etc. were killed on the night of the Uchiha Clan Massacre. Itachi later died himself, leaving "Tobi" as Sasuke's sole family member. Their relationship (uncle, cousins, grandparent, etc.) is unknown. TO CLARIFY ON TOBI'S IDENTITY AS AN UCHIHA: Tobi is confirmed to be Obito Uchiha. Obito was originally believed to have died as a teen after being half-crushed by a boulder saving Kakashi Hatake, but was revealed to have survived, and the evidence from the boulder are on his face, even now as an adult. He later claimed to be Madara Uchiha, but it was revealed that he was ordered to do so by the REAL Madara. The real Madara Uchiha is currently dead.
