The Shadow Clone Technique is a popular ability in the anime and manga series Naruto. It allows a user to create multiple copies of themselves, known as clones, that can act independently. Unlike simple clones, these shadow clones have physical substance and can perform jutsu, making them effective in combat and training. This technique requires a significant amount of chakra, the energy source in the Naruto universe. It is often used by skilled ninjas like Naruto Uzumaki to overwhelm opponents or gather information quickly. The ability to create shadow clones is a hallmark of advanced ninja techniques in the series.
