|Lex Clone LX-Ø|
|Portrayed by:||Michael Rosenbaum|
Our story hasn't been written yet, Kal-El. And every villain is only as great as his hero. But, you see, that all relies on you saving us from the coming Apokolips.
|Lex Clone LX-Ø to Clark Kent.|
Unknown to anyone for some time, Lex took his failed clones' best pieces to create a perfected, composite clone LX-Ø. Unfortunately, he was unable to successfully duplicate a heart at the time. After Lex's “masterwork” is discovered by a parallel reality Lionel Luthor, Lionel's biomedical research company tried to locate Conner Kent (a Human/Kryptonian hybrid clone made from half of Clark Kent's DNA and half of Lex Luthor's DNA) for a heart to give LX-Ø but Tess's efforts to hide Conner forced Lionel decide to use Tess as a last resort.
While Apokolips (a planet which resembles a massive sphere, with fiery pits emanating from around it) was approaching the Earth and after Tess escaped and shot Lionel for planning on using her heart to revitalize LX-Ø, Lionel desperately crawled toward LX-Ø to which Lionel and Darkseid made an exchange: Darkseid (a very powerful alien entity associated with the planet Apokolips) would give Lionel's heart to LX-Ø while Lionel surrendered his own soul to Darkseid in the process.
Completely restored, LX-Ø noticed the parallel reality-Lionel's change of heart and met with Clark at the Luthor Mansion's remains. LX-Ø told Clark that he embraced his destiny as Clark's nemesis. He was then able to encourage Clark to go fight Darkseid, saying that Clark couldn't defeat Darkseid but they both knew who could.
LX-Ø later arrived at LuthorCorp and confronted Tess, revealing he knew that she was his sister all along and the fact that she shot the parallel reality-Lionel (who only wanted Lex back). He told her he loved her and the two siblings embraced. Subsequently, LX-Ø stabbed Tess with a long blade. As Tess died, LX-Ø said he was saving her from becoming him, to which she said Clark already has. Tess then rubbed a neurotoxin on his face, which interfered with his memory.
She told him he had 30 seconds until his memories were wiped. He forgot everything that happened throughout his original self's life in Smallville. LX-Ø looked out of the office window at the coming Apokolips while its chaotic damage “destroyed” LuthorCorp, leaving behind LexCorp in its place.
