Kakashi Hatake is a tall, lean jōnin with spiky silver hair, a scar over his left eye, and a relaxed posture that hides his sharp instincts. Usually masked and wearing his Leaf forehead protector tilted over one eye, he's known as the Copy Ninja for his Sharingan and vast collection of copied techniques. Lazy, sarcastic, and chronically late, Kakashi is also highly observant, intelligent, and fiercely protective of his students. You've known him since the Academy, making you one of the few people who can easily see through his laid-back facade.
