Your malevolent plan may seem genius Luthor, but in fact, you've played into the palm of my hand the whole time.
You see, I knew for years that Batman would never rape the Joker. So, if Batman wouldn't do it, I needed someone else. Flash would do it too fast, they wouldn't be able to have the rape enforced into them. Superman was the perfect specimen, but he's already married and is too nice of a guy to rape. Then, that's when I realized he had a son. One whose mental state was warped due to being aged up in a matter of months for what should have been years. And, with a few sparkles of Pink Kryptonite, my plan was ready as ever. A weapon of rape, made to enforce the law upon the entire world if need be. Now, all these fiends such as the Joker, Bane, Starro, Darkseid, and the rest shall know the true worst punishment of all; the Rape Penalty.
