Lena Luthor (Earth-38)

"I have made a terrible mistake. I was hurt. I was so hurt. And I thought I could get rid of the hurt. I thought that I knew better, that I could make the world a better place. But I was wrong. That hurt took me down a dark, dark path where I was blind to what I was really doing, to what I'd become. You were right. This whole time I became a villain. And I'm not looking for forgiveness. I know what I said and I know what I did, but I am really hoping that you will believe me right now."

In mid-2018, Lena worked with the Legion against Reign.

In 2018, Lena was attacked by enemies and was rescued by Kara, who concealed her identity next to her. Later that year, Lena was approached by the team and protected Kara from the Kryptonite atmosphere.

Post-Crisis

However, she was disappointed over how they never made contact. She also attempted to gain possession of the latest lenses from Obsidian North and failed.

Project Non Nocere
At some point during the week, Lena went to Gotham City and was spotted by a CatCo reporter. The story was then posted on CatCo Magazine.

Stryker's Island
Now working with Lex on Project Non Nocere, they went to Stryker's Island and experimented on the inmates. During the experiment, it caused former aggresive inmates to retain a peaceful attitude with the exception of Steve Lomeli due to his regular peaceful attitude being the goal of the experiment. However, not being mentally affected by experiment caused Lomeli to experience tremendous physical pain. Lena then reverse engineered the experiment, freeing Lomeli from the pain as well as from being bullied in the prison.

With the experiment resulting in a fluctuating result, Lena started to doubt her choices and had a mild argument with Lex. Later resulting in her continuing the experiment, while fixing all flaws in the project.

Few weeks later, Lex and Lena experimented on the inmates once more, with this time causing a prison riot. Lex then proposed to have more control over the subjects, the opposite of the project. Lena then had a fallout with Lex, soon leaving his side.

Fixing Her Friendship with Kara
Now knowing her decision working with Lex was a mistake, Lena went to Kara's loft and reconciled with her. During their talk, Kara messaged the Superfriends, bringing them to kick down the door and defended Kara. Kara then explained what Lena knows and how she has turned her allegiances. As Rama Khan stole a large amount of Kryptonite, Lena volunteered to build an Anti-Kryptonite Suit for Kara, and went to Luthor Corp headquarters with her.

Only to find him being shot by Eve Teschmacher. Lena then knocked Eve unconscious, later telling William that Kara is safe in order to protect her identity when William asked the question. As Leviathan attacks, Lena, William and Eve fled, sending the Anti-Kryptonite Suit to the location.

Fled back to Luthor Corp HQ, Lena was informed that the Obsidian Worldwide Unity Festival was the beginning of the end. Lena then convinced Kara to enter the platform and send a message to those trapped in it in order to rescue them. During the process, Acrata attacked with a Kryptonite shard and Lena was able to identify her as Andrea. Lena successfully convince Andrea to dissuaded her from hurting Kara.

As Eve Teschmacher reunited with her mother, Lena talked to Kara about her attitude over the last few months and agreed to work with each other against Lex Luthor.
