Adrian Cross was a faulty clone of Lex Luthor's deceased brother Julian in the WB/CW TV series Smallville.
He served as the main antagonist in the Season 7 episode "Gemini".
He was portrayed by Tim Guinee.
Adrian was manufactured by Lex's secret Project Gemini. He was programmed with a set of false memories in order to live a life in the outside world. He claimed to be the first clone to survive the project, but a defect in his genetic sequencing caused him to age at an accelerated pace.
Lex would later succeed in creating a stable clone of Julian naming him Grant Gabriel and discarded Adrian. Determined to expose Lex's wrongdoings before his death, Adrian went to extreme lengths to complete his goal.
First, Adrian planted a bomb on Chloe Sullivan's secret Santa gift. Then he left a cellphone for Lois Lane to answer despite it not belonging to her. Adrian tells her that Chloe had a bomb on her and if she doesn't stop ignoring him, Chloe will die.
Adrian told Lois his name and tells her his story of being an escaped clone from LuthorCorp, his body was aging at a rapid rate and he expects to die very soon. As they talked, Lois attempted to e-mail Chloe to warn her, but her internet line is cut.
Adrian called her again and warns her not to disobey him. Frightened Lois mistook a delivery man as Adrian and confronted him but he thought she was crazy. As he turned to leave, he fell back toward Lois, dead from being stabbed with a pair of scissors.
Lois' cell phone rings and Adrian warns her to keep her mouth shut. Lois still attempted to warn Chloe about the bomb. She tried to get a woman to deliver a manila envelope to Chloe which has the warning written on the back.
The woman hands the letter to Chloe, who tells Lois that Clark is back and she is leaving to go visit him. At this time, Lois receives a text message from Adrian, warning Lois not to tell Chloe anything. Chloe suspected that something was bothering Lois, but she doesn't say anything.
Chloe shares an awkward elevator ride with Jimmy when she turned the envelope over and reads Lois' warning message about the bomb.
At that moment, the elevator suddenly brakes, trapping Chloe and Jimmy with the bomb. Lois notices an "out of service" sign on the elevator. She begins to walk toward it, but is stopped by Adrian, who is holding the detonator in his hand and demanding his story.
Lois showed Adrian her article about LuthorCorp's first clone. Adrian tells her about his family and his Christmas memories, then reveals that they were all fictitious memories downloaded into his brain. Lois promises to publish the story if Adrian will let Chloe go, but Adrian has another mission for Lois. She must force Lex to confess what he's done.
Using Chloe as leverage, Adrian forced Lois to use her scheduled interview with Lex as a platform to get him to admit knowledge and responsibility of Project Gemini. Lois went to her interview wearing a hidden camera and a device in her ear which allows Adrian to talk to her.
If she can't get a confession from Lex, Adrian will kill Chloe. Grant and Lex were both waiting for Lois, but they are surprised with her first question, a demand to know about Project Gemini.
Adrian is still communicating with her through her earpiece, telling her exactly what to do. Lex claims he doesn't have anything to do with cloning and he denies knowing a man named Adrian. Adrian orders Lois to aim a gun at Grant to get Lex to confess.
Lois begins ranting about Adrian's life story. Lex knocks her out and finds the hidden camera she was wearing. Shortly after, Adrian enters and tells Lex and Grant about more of his memories.
Grant soon realizes that they have the exact same memories, even talking about their past experiences simultaneously. Adrian also says that they have the same DNA and history, only Adrian was a failed experiment and Grant was a successful one.
In an outburst of anger, Lex shoots and kills Adrian, saying he was just a mistake. In his last seconds of life, Adrian presses the button on the bomb's detonator.
However, Chloe and Jimmy were able to be rescued by Bizarro posing as Clark Kent. As a result of Adrian's appearance, a rift emerged between Lex and Grant that was never resolved until Lex had Grant killed.
