Chidori is a powerful lightning-based technique used in the Naruto anime and manga series. It was created by the character Kakashi Hatake and is primarily associated with Sasuke Uchiha. The technique involves the user channeling a large amount of electrical energy into their hand, creating a distinctive chirping sound similar to a bird. When executed, Chidori allows the user to strike opponents with immense speed and force, delivering a devastating electric shock. It is often used in close combat situations and requires a high level of chakra control. Over time, Sasuke develops variations of the technique, enhancing its power and effectiveness.
