Lena Luthor - Modern Version

Modern Version

In Final Crisis: Legion of 3 Worlds #3, Legionnaires Polar Boy, Wildfire, and Dawnstar travel to Smallville during the 20th Century, back to when Superman was still a suburban legend. The three heroes arrive to the Luthor household, where they hear a young Lex Luthor arguing with his father about his mother and sister.

In the revived Adventure Comics, Lena is Lex Luthor's younger sister and grew up alongside Lex until he left Smallville. Lex made certain to cover-up his Smallville history, and that included disavowing a connection to his sister. Lena is now an invalid, living in Smallville with her daughter Lori. Lori became friends with Superboy, but both were shocked to find Luthor on Lori's doorstep, intent on taking control of Superboy again and claiming he can cure Lena's condition. With Superboy's help Luthor indeed cures Lena, but he then undoes his cure, claiming he only helped her to prove to Superboy that he could and that so long as Superman lives, he will never reveal how he did it. Currently Lena is under the care of Wayne Enterprise doctors, thanks to Red Robin.
