Demo version: Defeating Orochimaru
When you are on the episode fighting Orochimaru, you may think it is easy, but it is not. He uses a lot of attacks and he blocks requently. As the Third Hokage you may be able to defeat him. When Orochimaru uses the attack while sending out worms out of his sleeve, jump and attack from above. When he uses his tongue and turns it to a snake, use your staff to knock down Orochimaru. He will then make his neck longer. This will be the difficult part. He will try to attack anywhere. Make sure you walk to block his attack. After a few attacks he will use his Jutsu. He will try to make you stand still, then he will attack and you will lose. Try to jump over Orochimaru and make sure your Chakra gauge is full. Then, use your Jutsu behind him to defeat Orochimaru. Now it is time to fight Gaara.
