Born of a Romalian father (who supposedly had "second sight") and an American mother from Bangor, Maine, Crystal Ball actually was the seventh son of a seventh son . . . and such men, the gypsies of old believed, were possessed of supernatural powers. That may or may not be true, but Crystal Ball can sometimes read minds, making him a unique addition to the Cobra forces, especially as an interrogator of captured Joes. Cobra doesn't use torture to interrogate their prisoners; when Crystal Ball is having one of his good days, they simply don't need to.
