Multiple Shadow Clone Technique

This technique is essentially a massive version of the Shadow Clone Technique. Instead of a few clones, it creates a few hundred clones (or a number of equal grandeur). This is considered a kinjutsu, because it can potentially be dangerous to the person performing it, seeing as how all of the clones are given an equal amount of chakra directly from the user. Naruto learned the technique from the scroll of forbidden seals.

Few people are able to use this technique effectively, due to the large amount of chakra it consumes. However, this weakness is not an issue to Naruto, due to his massive chakra reserves. Having such reserves allows him to create hundreds of clones while maintaining a decent supply of chakra in each one. This technique is also used by Naruto to train quickly, since all the clones share their experiences with Naruto, but it causes extreme fatigue with repeated use.

Naruto is shown to use this technique on multiple occasions to form human chains, for both offensive and supplementary reasons.

Trivia

 * Naruto sometimes does not appear to distinguish between the Multiple and regular variations of the technique, and often simply says "Shadow Clone Technique" regardless of how many clones he uses.
 * At the end of Prologue — Land of Waves, Kakashi notes that he does not have enough chakra to take on Gatō's thugs. Despite this, he uses a Multiple Shadow Clone Technique to create several dozen copies of himself as a bluff, scaring them away.
 * According to Kakashi Hiden: Lightning in the Icy Sky, after losing his right arm but before gaining a prosthetic, Naruto learned to make the seals necessary by making a cross with his left hand’s index finger and middle finger by entwining them.
 * Boruto Uzumaki was able to use this technique using a special forearm device in Boruto: Naruto the Movie.
 * Hōki created the facade of copying this technique from Naruto by using a visual projector.
