He gains a lot of skill and power.
Sasuke joins Orochimaru in the end of episode 109 but everyone(except Sakura) finds out in episode 110
i think she loves naruto its a possibility that she loves naruto but you still have to keep in mind that she never stopped loving sasuke
Naruto fails to stop Sasuke and leaves on a journey with Jiraiya. Sasuke joins Orochimaru. Sakura starts her medical training. Then there is the side story called Kakashi gaiden, that shows how Kakashi got his Sharingan.
At the end of Naruto (original) Sasuke wants power and joins orochimaru. In Shippuden Sasuke gets stronger and more evil by killing more people. Sasuke kills Orochimaru and joins the Akatsuki. Right now Sasuke's target is Naruto and Konohagakaru.
When Orochimaru was transforming, Sasuke enters the room and tried to kill him. Orochimaru is in Sasuke, but Sasuke took over Orchimaru so Sasuke has full control of his own body. During Itachi's final battle, Itachi finds that Orochimaru is still alive in Sasuke, so Itachi drove Orochimaru out and kills him. Part of Orochimaru is in Kabuto after Sasuke and Orochimaru's fight, so Orochimaru might not be dead, but Orochimaru is mainly killed by Sasuke. The answers you find here are all found from the manga we read.
no, but orochimaru does.......
Hmm... how should I answer this question? Simply put, Orochimaru was not killed by Itachi, but by Sasuke. Sasuke killed Orochimaru in Orochimaru's weakest condition, knowing that Orochimaru had no more power to grant him.
yup sasuke marries sakura (sasuke kills orochimaru) and naruto marries hinata
he didn't Sasuke killed Orochimaru himself ,well sort of.
Sasuke Uchiha has the 'Sharingan' ability, an asset that Orochimaru would find very useful. Also, Sasuke is a very powerful Ninja, already adept at Taijutsu, Genjutsu and Ninjutsu. Orochimaru has already managed to put a curse upon Sasuke, which lends Sasuke a portion of Orochimaru's power at certain points. Orochimaru believes that by lending him such power, Sasuke will hunt for more, eventually leading him to find Orochimaru. Another reason is that Orochimaru eventually wants to take over Sasuke's Body because he is so powerfull. once Sasuke kills Itachi, Orochimaru Plans to inhabit Sasuke's soul.
In shippden Sasuke is getting taught under Orochimaru while Sakura is by Tsunade and Naruto is traveling with Jiraya. But Sasuke eventually kills itachi but relizes his brother was acutally ordered (itachi used to be in the anbu) by the hokage to kill all uchiha and he had no choice, but left sasuke alive. Then sasuke kills orochimaru and changes his team name (orochimaru put sasuke in a team called snake) to team Hawk with karin, Suigetsu, and Jirou. Then all team hawk joins the akasuki. Now team hawk is planning to destroy konoha for revenge of the hokage of killing the uchiha. Madara (leader of akasuki), sasuke, and Kakashi are now the only ones with sharingan.
Actually Sasuke kills Orochimaru >spoiler<
