You have to go to Saffron City and get through Silph Co. After you get Team Rocket out, the president of Silph Co. will give you the Silph Scope. Go back and find the ghost. Its true identity will be unveiled, but I wont tell you who it is, and you can battle it. But beware- YOU CANNOT CATCH THIS POKÉMON! It is a waste of pokéballs to even try, and PLEASE don't waste your masterball on it, if you have it yet. I did that once... not fun to try and get through it with no masterball. So don't.
