you cannot beat a ghost in lavender tower because your pokemon are too scared to fight them, however if you unmask them you may battle and defeat them. to unmask then you need the silph scope, which you can get from team rocket hideout, after beating giovanni. and unmasked ghost may either be a ghastly, haunter, cubone or if it is the boss ghost, it is cubone's mother marowak.
