Ok, so I think that this jutsu I have choosen is a fairly powerful jutsu, without doing anything at all. It is 3-prong Sharingan, which is used by all members of the Uchiha clan that have activated the 3-prong, Sasuke Uchiha, Itachi Uchiha, and Kakashi Hatake. This is not just a jutsu, but a kekkei genkai, and it allows the user to copy and jutsu they observe while sharingan is active, but not perfectly. It doesn't have many defensive capabilities other than being able to predict what the opponent is going to do just a few seconds before he does it. Well, that is my #9 pick, I hope everyone enjoyed reading, and please comment.
