With this technique Pain allocates a portion of an individual's chakra and transfers it into a living human sacrifice. The human sacrifice takes on the appearance and abilities of the individual, essentially becoming a physically identical copy of them. The copy can then be controlled from a distance by the original and used to fight battles in their stead.
The technique will imitate any weapons, tools or even kekkei genkai held by the original person, allowing the copy to fight with them. The power of the copy is in proportion to the volume of allocated chakra, which is decided by Pain. All of the original's techniques are also available, yet once the chakra given to the copy runs out or the copy is defeated, the technique is cancelled. Afterwards the copy's appearance will revert back to the original appearance of the sacrifice.
While the appearance of the copy during the Shapeshifting Technique is completely perfect, it is possible for someone who has experience fighting with the original person to detect something is amiss. Exactly what is amiss is usually not realised until the copy has been defeated.
