Mind Body Switch Technique

The Mind Body Switch Technique is the signature ability of the Yamanaka clan. With it, a ninja sends his mind into a target's body supplanting the target's mind with his own. More skilled ninja are also able to switch to more than one body as showed by Ino during the war. The user transfers their consciousness to the target, giving them complete control of the body for a short period of time.

Their original body is left defenceless while this jutsu is active, leaving it susceptible to attack until they return. The mind transfer moves in a straight direction and takes some time to return to the user's body if it misses. Because of these reasons, it should only be used on immobilized targets. Similarly, if the opponent's will is strong enough, they can force the user from their body, as Sakura Haruno did to Ino Yamanaka in the Chūnin Exams. Lastly, should any physical injury befall the victim's body while the mind-link is active, it would cause the user's body to also receive those same injuries. This can be rectified if user cancels the jutsu before the victim's body receives the damage.

Trivia

 * In Naruto Shippūden 3: Inheritors of the Will of Fire, Ino uses a different hand seal to perform this technique.
 * During the Fourth Shinobi World War arc, the Mind Body Switch Technique is used in a number of ways that deviate from earlier depictions and explanations of the jutsu.
 * When Santa Yamanaka used this technique on Kakashi Hatake, he gained control of Kakashi's body while Kakashi gained control of Santa's.
 * Ino uses it to possess two targets at once while both were seemingly incapacitated at the time. During this same instance, the jutsu travels in a curved line to each target, rather than the typically observed straight direction.
