If you bypass the manga and anime, I have heard a theory on this. Yamata no Orochi is an 8 headed snake bijuu from Japanese mythology. Now, you can already see the resemblance. Before the Villages and such, i have heard or seen hints and which all the clans were separate militias, always fighting. One of these clans was the Orochi clan, which worshiped Yamata no Orochi. They somehow gathered the power of Yamata no Orochi and became very powerful. The Kusanagi, Senju, and Yata clans all banded together to defeat the evil Orochi. The Orochi defeated all but the senju, and the Senju defeated them. Now, The Senju had sealed the Yamata no Orochi and had defeated its followers, the Orochi clan. Since they had sealedit and not killed it, they had to let one of the orochi survive to let the beast (Possibly close to a god) survive within him. The one they let live was you guessed it, Orochimaru. He is the only Survivor of the Orochi clan.

For power. Orochimaru told Sasuke he could help, and so to avenge his clan and defeat his brother, sasuke turns to orochimaru.
No, only members of the Hyuuga clan have Byakugan, like Hinata and Neji. Anko has a curse mark from Orochimaru though
No, Orochimaru is a boy.
Tsunade is stronger in strenth.But Orochimaru is stronger in skill.But to my opion Orochimaru's somuning is stronger.So my opion is Orochimaru
no, but orochimaru does.......
yes sauske does kill orochimaru when orochimaru tries to transfer into sauske's body
No,Sasuke killed Orochimaru then Kabuto used Orochimaru's body.
orochimaru is the very powreful person
No. Naruto absolutely despises Orochimaru.
Orochimaru's blood type is B.
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.
Orochimaru collected good ninjas like Tayuya and give them curse seal. To learn to control that seal they have to learn from Orochimaru. So she served Orochimaru as her own master.
