Clone Technique

This technique creates intangible copies of the user. The clones are simply illusions and will dissipate when they come into contact with something. The illusions can be seen through by the Byakugan and the Sharingan. A person with normal eyes can also distinguish the clones from the original, since the clones do not have shadows and will not disrupt the area around themselves with their movement (won't kick up dust, crush grass, etc.).

Trivia

 * In Konoha, to be promoted from Academy Student to genin, students are required to properly produce at least three clones with this technique as part of their evaluation. However, Naruto Uzumaki and Rock Lee are the only two ninja known to pass through the Academy without mastering this technique.
