Nightmare Fuel / Elseworld's Finest: Supergirl & Batgirl

---

• Pa and Ma Kent never found Kal-El's rocket. Lex Luthor did. And then he murdered the baby.
• After murdering him, Lex examined his body and his sunlight-absorbing cells and developed a solar battery. Luthor owes his fortune and Metropolis its prosperity to a murdered baby. And the casual, smug way he goes "it was an alien, who cares?" when Supergirl confronts him about it is a perfect showcase of someone being a sociopath.
• And he intended to murder Supergirl, too.
• The Joker's obsession with Batgirl is dumb but amusing... until you read The Killing Joke and Death of the Family.
