What Is Black Kryptonite?
Like most other forms of the deadly element, Black Kryptonite emerged with the explosion of Krypton. It actually originally debuted in the Smallville episode “Crusade,” and made its comic book debut in Supergirl (2005) #2. Those two appearances showed it as separating the affected person into two halves; one good, and one evil. However, all of its subsequent uses have instead depicted it as altering the mind of the person it affects, inverting their morality and turning them into murderous monsters. It made its first post-New 52 appearance in The Batman Who Laughs #1, where the Dark Multiverse version of Batman used it to have Superman and Jon Kent kill their family before it killed them. However, that was a different universe, and for a long time Black Kryptonite was absent from the main DC Universe. Now it’s back, and worse than ever.
Rise of Satan Girl and Krypto the Satan Dog
Supergirl is dealing with an imposter. Her hometown of Midvale has been convinced that Lesla-Lar, a Kryptonian from the Bottle City of Kandor, is the real Supergirl, and Kara is the imposter. She’s gone as far as to brainwash the Danvers into thinking she was their daughter instead of Kara, and the only person still on Kara’s side is Lena Luthor. Still, even if the entire town is calling her Phonygirl, that’s not going to stop Kara from being a hero. She continued to fly about Midvale and solve problems, getting everyone to love her, even if they think she’s trying to cut in on Supergirl’s fame. Lesla-Lar, meanwhile, is completely taken aback that the town turns on her so quickly. She is obsessed with Supergirl and desperately jealous of the attention she receives, but fails to understand that people treat her well because she is a hero who isn’t seeking reward. Wanting the town to hate Supergirl as much as Lesla does, she exposes the superheroine to Black Kryptonite. Supergirl and Krypto are completely transformed into moralless villains, with Kara redubbing herself Satan Girl.
