Marsha, the Queen of Diamonds, is after the giant diamond that powers the Batcomputer. With her love darts, she puts both Commissioner Gordon and Chief O'Hara under her spell (and into her custody). When the Dynamic Duo show up, they too are injected with her love potion, and Batman must agree to marry Marsha if he ever wants his friends to be returned.
Did You Know?
Marsha is a spin on Mortisha, the character from The Addams Family that actress Caroline Jones is best known for portraying, and was such at the time too. Even tho Marsha and Morticia where two very different characters, she was still given a very Addams Family-esk side-kick and witch in Aunt Hilda. See more
Where is Chief O'Hara? What have you done with him, you diabolical Mata Hari? If you've harmed a hear on O'Hara's head, I'll have you in jail for the rest of your life.
Oh, don't be tiresome, darling. Here, sit down next to me and relax.
Your hanky-panky won't work with me, young lady, I want O'Hara.
