Orochimaru bites Sasuke during their battle in the Forest of Death during the Chunin Exams. Specifically, Orochimaru bites Sasuke's neck in an attempt to transfer his consciousness into Sasuke's body.
The time Sasuke is escorted out of the village by the Sound 4 and Shikamaru, Neji, Kiba, Chouji and Naruto follow them soon after is during the Sasuke Retrieval Arc. It's on episodes 107-135 and chapters 172-238. In the Sasuke and Sai Arc, the new Team 7 heads out and in the end, ultimately finds Sasuke, leading to an awkward reunion. This is on episodes 33-53 of Shippuden. In the Five Kage Summit Arc, Sakura leaves to hunt down and kill Sasuke. Naruto and Kakashi run after her, leading to another Team 7 reunion. I'm not sure if there are other instances.
Yes, Tayuya, a character from the "Naruto" series, remains dead after her defeat during the Sasuke Retrieval Arc. She is killed by the character Kimimaro, and her death is confirmed in the storyline. There are no subsequent appearances or resurrections for her character in the main series or its sequels.
Itachi removed it and killed Orochimaru during his fight with sasuke.
no during naruto's battle with sasuke, sasuke kills the nine tail fox.
Orchimaru
during the old times im pretty sure sasuke cares for sakura only like a sister............
Its probably from Sasuke's sword during their final fight.
to store data during proccessing and for later retrieval.
SPOILER ALERT: Sasuke first met karin in the forest of death during the chunin exam, but you first see them "meeting" each other two episodes after sasuke kills orochimaru.
They are equal in Power .During their latest battle, Sasuke won (it was very tight though), it is unclear who will win this time.
During the episode 51-52 special.
