I have a question about both of them. Kakashi`s Mangekyou Sharingan can send a person or an object to another dimension right? Then how come Deidara found his arm then. Shouldn`t the arm be in another dimension? My Itachi question was about his Amaterasu. Can it burn anything in an instant. More importantly can it burn people? Wouldn`t this be the strongest thing ever. If it could just simply burn u up out of no where or can it only burn objects like Jiraiya`s frog stomache? Answers?
