There's only about nine hundred 'Cassandras' out there, usually with some kind of future vision or prophecy ability, and 'Cain' should just be retired from comics for good. But it doesn't help that she has one of the WORST regular names in comics. Double-so for any character with over 70 issues of a solo book under their belt. She's an interesting look at characters involved in the Batverse, because up until her, there had been almost no 'also-ran' characters in the Batman family.
