10 ways to beat the Sharingan and the Byakugan

1. Since the abovementioned bloodline limits uses sight, one can use the method Zabuza used when fighting Kakashi: which is to use some kind of jutsus to make mist appear. However, since it would require quite a bit of chakra to make the mist thick enough and since you obviously won't be able to see anything as well, it would not be entirely adviseable to do it unless you are able to locate your enemies using sound like Zabuza as not being to see anything will put you at a disadvantage.

2. Do something about eyes. For example, if you should succeed in poking or gauging the eyes out, then the Sharingan/Byakugan user would be helpless against you. However, since the process of just getting near enough to do that would enable the Byakugan user to do something to your tenkutsu, using some kind of weapon to do that would be more advisable.

3. Throw something in the air which will irritate the eyes. A fine example would be pepper, which is light enough to stay in the air long enough for you to beat him/her and is easy to carry around, unlike sand, which despite being extremely undesirable anywhere near the eyes is very heavy when carried around in large quantities and will only serve as a distraction for only a few seconds.

4. Attack from behind or from below, where you should be out of a Sharingan user's line of vision, thus preventing him/her to seeing or copying or countering any jutsu you may use. However, never try this on a Byakugan user who has his/her Byakugan activated as the Byakugan allows the user to see 360 degrees around him/her.

5. Blindfold them. However, since this will only work if you actually manage to blindfold them and will only work if the Byakugan user does not activate the Byakugan, it is not very advisable to attempt it.

6. Spray some kind of liquid into their eyes which will cause temporary blindness. However, you can use something which will cause permanment blindness if you want to.

7. Use some kind of jutsu which will drain them of chakra, which should work since both the Sharingan and the Byakugan need chakra to work.

8. Attack by surprise. Since they would need a few seconds to recover from shock and react accordingly to the situation, it should give you at least a few seconds to finish them off.

9. Use some kind of disraction.

10. Attack when they are sleeping. Since everyone closes their eyes when sleeping, there is no reason why this should not work unless you fail to check whether they are really asleep or you are clumsy or noisy enough to accidentally wake them up.

Notes: Happily, this turned out better than I had expected. Please review!
