This article is about Tess of Earth-2. For her Earth doppelganger, see Tess Mercer.
|Family||Lionel Luthor (father, deceased), Lex Luthor (half-brother, deceased), Clark Luthor (adopted brother)|
|Occupation||Former Stockholder of LuthorCorp|
|Played By||Cassidy Freeman|
In an alternate Earth where Lionel found the Traveler in Smallville and raised him as his son, Tess grew up knowing that Lionel was her father and that Lex was her half-brother and was raised by him but was disowned because she was not "special".
Despite being adopted siblings, Tess was having a passionate affair with Clark and together planned to use Lionel's mirror box to escape to Earth-1 and make it their own. When Clark Kent was sent to this darker Earth, Tess did not take long to realize that they were not the same person and helped Clark realize what happened.
After trying to get information about the Kryptonian device from Lionel's office, she was discovered by him and after a heated argument where Tess claimed that he never loved her, she was arrested by security for having slapped Lionel.
It is mentioned by Earth-2's Chloe Sullivan that the planet was destroyed, meaning Tess was probably killed as well.
