Lena Luthor II

Lena Luthor is the daughter of Lex Luthor and Contessa Erica Del Portenza in the Post-Crisis universe. She is named after Lex's foster sister who had been killed by their foster father, Casey Griggs. After Lena's birth, Lex takes advantage of Contessa Erica's wish to be unconscious at child birth by keeping her permanently drugged and unconscious at his corporate headquarters, not wishing to share his daughter's love with anyone else (Although he himself avoids attending the birth to provide himself with a clear alibi for an assassination attempt he arranged at the time).
