- Lena Luthor on her mother

An unnamed woman (died 1997) was the mother of Lena Luthor and the lover of the late Lionel Luthor.

Biography
The woman started having an affair with billionaire Lionel Luthor sometime after the birth of his son, Lex. Eventually, Lionel's wife Lillian discovered the affair when she surprised Lionel and the woman together on a business trip. Lionel decided to send the woman, who was pregnant with their child, away in order to rebuild things with his wife and she was paid to keep quiet about the affair and stay away from the Luthor family.

In 1993, the woman gave birth to a daughter, whom she named Lena, and the two were very close.

Four years later, the woman took Lena out to a lake during a cloudy day, where she went swimming while her daughter watched nearby from the shore. Unfortunately while swimming, the woman drowned in the lake and died.

Legacy
After the woman's death, Lionel took in their illegitimate daughter and welcomed Lena into the Luthor family.

Lena felt great guilt over her mother's death, as she had frozen in fear upon witnessing her drowning, and wondered if she truly deserved the horrible legacy of the Luthor family.

Personality
The woman was a very loving and devoted mother to her daughter Lena, who looked up to her as a hero. She had a playful, free-spirited disposition with a love for the outdoors.
