|“||I don't think so. I'm from out of town. Unexpected visit. But I guess I'm back in the nick of time. Wouldn't want to miss how it all turns out.||„|
|~ Lionel (Earth-2), to a newspaper vendor after arriving on Earth-1 and breaking the fourth wall, "Luthor".|
The Earth-2 version of Lionel Luthor in the CW TV series Smallville appeared in four episodes of the show's Tenth and final season.
Like his normal universe counterpart, he was portrayed by John Glover, who also played Dr. Jason Woodrue in Batman & Robin, Mr. Sivana in Shazam!, Verad Kalon in Star Trek: Deep Space Nine, Theodore Maddox in Fear the Walking Dead and voiced The Riddler in Batman: The Animated Series.
Lionel first appears when Clark Kent accidentally activates the mirror box, a Kryptonian device that transports him to Earth-2, an alternate universe where Kal-El was found and adopted by Lionel Luthor rather than the Kents. Lionel named Kal-El "Clark Luthor" and raised him to become his enforcer as he successfully took over Metropolis.
He also allowed Clark Luthor to kill that Earth's Lex Luthor, though he came to regret it. After Lionel lectured Clark, they dueled with swords laced with blue kryptonite.
Lionel later caught Tess sneaking around into Lionel's office to get a hold of a journal that had information regarding the mirror box. Lionel catches her and finds what she was after - a drawing of the mirror box. Lionel and Tess have a heated argument about how she is a disappointment.
Tess slapped Lionel after he called her a half-bred tramp, and Lionel calls security. Before security takes her away, she asks why he treated Clark better than her, to which he replies that she was never special enough. She then tells Lionel that Clark will eventually betray and kill him.
When Kent went to the Fortress of Solitude in the hopes of getting help from Jor-El, Lionel was there and had the Fortress integrated with Earth technology to silence Jor-El. Lionel mentions to Kent that he saw Tess and asks why they were both after the mirror box.
Kent lies and tells Lionel he wants it so he can destroy it. Lionel tells him that Oliver Queen has it, and Clark goes after it. Lionel starts to believe that Clark is going to betray him.
This was revealed to be a lie as Lionel himself had the Mirror Box. He had instead wanted to locate Oliver and to discover if Clark was going to betray him as he once assumed. Oliver had subdued Kent with kryptonite and was about to finish him off when Lionel intervened, hitting Oliver over the head.
Instead of helping Clark, Lionel said that he has failed him as a father and that if he was a true Luthor, he would have killed Lionel by now and Lionel blames himself.
Lionel starts to beat Clark K. with his belt as he rants about how only the strong survive and how he will be the strongest in this Earth or any other. At this point, Oliver realizes that Clark is the "good one" and turns off the kryptonite.
Clark Kent tells Oliver to turn on the kryptonite again when Clark Luthor returns and assures Oliver that in the other world, they do save the world together. Clark K. grabs the mirror box and activates it, while in the background, Lionel runs
By the end of the episode, Clark manages to retrieve the mirror box and use it to return to his world, but is unknowingly followed by Lionel. Lionel bought a newspaper from a vendor who recognizes him but Lionel responds by saying he just came in from out of town for an unexpected visit. He adds that he wouldn't want to miss how it all turns out then walks away into a crowd.
In "Beacon," Lionel reveals himself on the prime Earth, and proceeds to seize control of LuthorCorp from Tess Mercer and Oliver Queen, after researching everything to find out more about his doppelganger. He later travels to Suicide Slum, where he finds Alexander Luthor, a teenage clone of the original Lex Luthor, and takes him under his wing so he can groom him to be his successor.
He also tells him that in another life he betrayed his son and chose Clark, but now he plans to take advantage of this second chance and to make things right and rule the Luthor Dynasty with his son.
Oliver Queen later returned to LuthorCorp but when he walks in he finds Lionel-2 and Alexander. Lionel-2 explains that he has been quietly reclaiming his assets and bought out Oliver’s shares having taken control of LuthorCorp.
Oliver wanted to strike Lionel, but when he dares him to, Oliver restrains himself. Lionel-2 tells him that he was a fool to seek out the spotlight and how the people have turned against him once and they will do it again when the VRA repeal vote fails. Oliver-1 insists that people are full of surprises and that he will be back for Lionel-2 once his named has been cleared.
Later, he is confronted by Martha Kent, only for Alexander to knock Martha unconscious and turn against Lionel, whom he knocks out before setting fire to the Luthor Mansion. Fortunately, they are both saved by Clark Kent.
In "Scion," Lionel confronts Tess in the ruins of Cadmus Labs and disbelieves her claims that Alexander is dead (in actuality, Alexander was revealed to be a genetic clone of both Lex and Clark, and underwent a transformation into Conner Kent). When Conner runs away from the Kent Farm after learning that half of his DNA came from Lex, Lionel finds him in the ruins of the Luthor Mansion.
He gives him a Red Kryptonite ring, causing Conner to fall under the extraterrestrial mineral's personality-altering sway. Later, after Clark destroys the Red Kryptonite ring and restores Conner to normal, Lionel appears with a chunk of Green Kryptonite, weakening both Clark and Conner. He tries to drag Conner away, but Conner declares he's not a Luthor and destroys the Kryptonite with a burst of heat vision. Lionel then leaves the scene.
In the episode's final act, Lionel is sitting in his office at LuthorCorp when Tess comes in and informs him she has exposed him as a fraud, leading to Lionel being escorted out of the building by security guards. In the final scene, Lionel visits Lex's grave and expresses his wish that Lex was still alive. At that moment, Darkseid materializes from a cloud of smoke before a terrified Lionel.
In "Finale," Lionel has Tess taken captive with the intention to transplant her heart to LX-0, a "perfect" clone of Lex manufactured from other, less-than-perfect clones. However, Tess gets free, shoots Lionel, and escapes. Lionel, mortally wounded, opens the room containing LX-0 and crawls toward the table.
When Darkseid materializes offering him the deal that Lionel had previously turned down: to live forever. Lionel refused immortality instead asks him to restore Lex to life; Darkseid agrees in exchange for Lionel's soul and rips out Lionel's heart and transplants it into LX-0, restoring Lex to life.
Darkseid later inhabits Lionel's corpse to confront Clark. When Clark gains the power of flight, he flies through Darkseid, destroying his vessel and seemingly the villain himself.
