Lena Luthor is the younger sister of Alexis "Lex" Luthor. She was a toddler when her brother became a notorious criminal mastermind in his teenage years. Lex and Lena's parents were so ashamed of their son's crimes and reputation that they moved away from their home in Smallville with Lena and changed their surname to "Thorul"--"Luthor" inverted. Lena grew up with no knowledge of the fact that she had a brother or that he had become the arch-nemesis of Superman.
- This version of Lena Luthor, including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985-86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
