With his tongue!
For power. Orochimaru told Sasuke he could help, and so to avenge his clan and defeat his brother, sasuke turns to orochimaru.
He killed Orochimaru, for sure... lol itachi isn't dead sasuke and him still have to battle in shippuden and itachi will die cuz of to much use of the mangekyou duh and sasuke only killed orochimaru becuz he didnt have anything else to learn from him
To gain power from Orochimaru so he could kill Itachi
Sorta. Sasuke absorbed Orochimaru's body, so he gains all of his abilities etc, so technically he lives on. Regardless their is more to it in that in the manga. Later, Kabuto went hunting for Naruto, sucessfully finding him, he only wanted to chat though, during their chat he said how Naruto shown him the light and that he will become who he really wants to be, then showing that he had took Orochimaru's body inside on himself, he then said that Orochimaru was taking over his body, and that if it succesfully takes over Kabuto, he would be forever gone, meaning Orochimaru would come back. At that time Orochimaru took over 1/3rd of his body, by now he could be at 3/3, unless Kabuto got Orochimaru out somehow, though I don't think that is the case. Later Sasuke faced Itachi, Itachi (purpously) made Sasuke completely out of chakra, leaving Orochimaru open to take over Sasuke's body. Orochimaru then leaves Sasuke through the Curse Seal, where Itachi's Susanoo sucessfully seals Orochimaru forever in a genjutsu like world for eternity. So basically original Orochimaru is sealed forever inside a genjutsu like world, but a new Orochimaru is forming inside of Kabuto, one with the same personality, memories, desires etc etc. But this Orochimaru will be stronger as it is Kabuto + Orochimaru.
He went to Orochimaru and got really strong so he could be Itachi
*SPOILERS* Orochimaru is killed in a weakened state, in the hands of Sasuke. Along the line, Sasuke (stupidly) keeps Kabuto alive, which was a grave mistake, as Kabuto managed to fuse himself with Orochimaru and now he is running a full-blown war with the United Five Nations with "Madara" (who can no longer be validly known as Madara, as Madara is dead and revived as part of the Resurrection jutsu). In a nutshell, Orochimaru lives within Kabuto like Lord Voldemort lived within Harry Potter. Feel free to shudder.
My opinion and others think that Orochimaru is gay. Proof? Well when Anko and Orochimaru are fighting in the forest of death, Orochimaru turns round to Anko and says (Talking about Sasuke) "He's a beatiful boy" or "He's beautiful" Which is strange... But Orochimaru dosent like any one.... He's either Gay, Lesbian or a perv XD
so that orochimaru could see what he was seeing His secret is he serves orochimaru and all kabuto is doing is gathering information on naruto, sakura & sasuke for his master
Sort of. He gets kicked out because he fails a mission.
He was not ordered to leave the village. After he got bitten by Orochimaru, he was hungry for power and so he left on his own.
no after killing his brother he goes after ochimaru for more power by the time he kills itachi orochimaru is already dead sasuke kills both of them he said that he may not have been able to kill orochimaru if he wasnt in the weakened state itachi is a good guy he loved his brother and only killed the uchiha clan because he was ordered to the only reason left sasuke was so that sasuke could become strong nd kill him itachi freed sasuke from the cursed seal also sasuke has become a rouge criminal and wants to destroy naruto nd the konoha village
yes he has collected them since they first came out but no longer collects them because orochimaru wont let him buy anymore because they are too much money and also because he has too many and orochimaru doesn't have money to buy them but yes sasuke collects them and his favorite is the one with a star on its butt hole he thinks it's so cute he could kiss it and also gets realy angry when a new one comes out and orochimaru wont let him buy any more .
