Marsha, Queen of Diamonds/Marsha’s Scheme of Diamonds

New Villain Alert!!! This could be the worst one yet as Marsha, Queen of Diamonds steps on the scene to make Batman fall in love with her and give up the location to the Batcave for a giant diamond he has in there for some reason. It's 24 Karat Hilarity. Ugh. I hate myself for typing that.
