Similar to the Clone Technique, this jutsu creates clones of the user. Unlike the Clone Technique, these clones are actual copies, not illusions. The user's chakra is evenly distributed among every clone, giving each clone an equal fraction of the user's overall power. The clones are capable of performing jutsu on their own and can even bleed, but will usually disperse after one or two solid blows. They can also disperse on their own. The clones will be created in roughly the same condition as the original.
Shadow clones can't be distinguished from the actual person even by the Byakugan because the clones have the exact same amount of chakra and aren't made from any other substance. In the anime, Sasuke Uchiha claims that the Sharingan can distinguish clones from the original, however various events throughout the series seem to indicate that this is not the case, implying that the Sharingan was merely used to keep track of the original's movements.
