What happened to Lex Luthors Daughter?
Lex Luthor’s daughter Lena was a vessel for Braniac 2.5, until Lex made a deal with Brainiac 13 (future version) and gave away his own daughter in exchange of the technology and power of the city of tomorrow. Later, a grown-up Lena came back from the future, under the influence of Brainiac 13. Somehow reverted back to her infant form (yet with the mark of Brainiac on her forehead), Lena was returned to her father after Brainiac 13 was defeated.
