White Snake Possession

Orochimaru transfers his consciousness into a white snake where it slithers into a person's body and enabling Orochimaru to gain control of their body and mind. Similar to the Yamanaka clan technique, Mind Body Switch Technique where the user's original body is left defenceless after taking control of someone's body. Orochimaru used this technique to control Kajika and so test the extent of Sasuke's power.
