How do you unlock sharingon Sasuke in clash of ninja 2?

"when your using sasuke, you have a glowing chakra gage under the health bar. when the whole thing glows yellow and shines, with the numchuck, press the control stick directly down, and on the wii remote, hold it right side up, and hold the down key pad, and he will say "Sharingan!" that's how you can also use the chidori as a special jutsu "

Thats clash of ninja revoulution.... Not Naruto Clash of ninja two. I think, but im not usre cuz im trying to figure it out too XD, you have to get all the other characters, and get everything else in the shop.
