Lana Lang is a main character in the WB/CW TV series Smallville.
She is Clark Kent's first love but appeared as the main antagonist in the Seventh Season episode "Wrath".
Lana was the daughter of Laura and Lewis Lang. When she was three years old, her parents were killed in the meteor shower that hit Smallville in 1989. Her Aunt Nell adopted her and gave Lana a necklace made out of the same meteor that killed her parents as a memory.
They lived a mile away from the Kent Farm. During her years at Smallville High School, Lana was frequently the victim of various meteor freaks who meant her harm but was constantly saved by Clark Kent who loved her.
In her junior year of high school, she discovers that her mother had an affair with another man, Henry Small, was her biological father who had a different family.
When Lana discovered that she was not pregnant and instead and been injected with hormones, she began to harbor a deep, dark, secret hatred for Lex and Lionel Luthor for semi-forcing her into a marriage as well.
After her marriage to Lex ended, Lana felt the only the way to be truly free of the Luthors was to fake her death and leave Smallville. She was successful by using a clone of herself from a 33.1 facility in the explosion and went to Shanghai China to hide.
Lex managed to find her and offered Lana a chance to return to Smallville and she wouldn't face any repercussions.
Taking Lex on his offer, Lana returned and reunited with Clark and began to live with him at the farm. Unknown to Clark, Lana had stolen ten million dollars from Lex and used it to create the Isis Foundation.
It was designed to help meteor-infected victims of Level 33.1 but secretly housed numerous security screens to spy over the Luthor Mansion and Lex himself.
Lana's hatred for the Luthors grew increasingly and her desire for vengeance was kept hidden from Clark. Lana hired a deranged woman named Marilyn to hold Lionel captive but he managed to escape and confronted Lana warning her not to continue her descent to the dark side or something bad would happen to her.
Despite all this, Lana managed to fool Clark and made him try to get their relationship on track by being more honest with each other. During a romantic afternoon, a storm brewed and Clark was weakened by a piece of kryptonite.
As Lana picked it up to throw it away, lightning strikes the windmill and shoots through Lana and Clark. Clark's powers were incompletely transferred to her as Lana received some of his abilities.
While super-speeding, Lana had a faint purple aura. She enjoyed the fact that they were equals and took advantage of this by having sex, causing minor earthquakes across Smallville.
Concerned by the earthquakes, Chloe went to see Clark and discovered the true origin of the seismic tremors, which embarrassed and surprised her. Clark was surprised that Lana talks about their sex life with Chloe when Chloe whispered to Lana that she thought they couldn't have sex.
After Lana goes upstairs, Chloe warns Clark that it has gone badly before when Clark has had his powers siphoned off. Clark asks Chloe to keep an eye on Lana. Upstairs, Lana overhears them talking about her and becomes furious, breaking a mirror. Chloe takes Lana to the Talon where she tries to warn her, but Lana says she wants to use her powers to tell her story.
Her new abilities amplifying her anger, Lana wanted vengeance and to make Lex pay for his crimes. Lana returned to the Isis Foundation and monitored Lex who was discussing Project Scion with Dr. Jansen.
The dust from the Black Box had liquefied and it was sentient and alive, only subdued by meteor rock. Lex placed the information in his vault. Lana super speeds to the vault and burns it open with her heat vision, then took the data file on Project Scion.
While trying to cure her, Clark discovered the Isis Foundation and found out that she had been watching Lex for months. Lana went to the Daily Planet and interrupted an exchange between Lois and her editor, Grant Gabriel. Wanting revenge, she gives him the hard drive and reports that it will expose Lex.
When he refuses to do so with stolen evidence, Lana started to choke him. When Lois stepped in to intervene, Lana kicked her across the room and through a glass door, knocking her out. Lana declares that she will take care of Lex on her own.
Later, when Clark and Chloe arrived at the hospital to check on Lois, Clark admitted to Chloe that Lana would never intentionally do anything to hurt Lois, coming to the conclusion that Lana's powers were affecting her judgment. While trying to cure her, Clark discovered the Isis Foundation and found out that she had been watching Lex for months.
Lex was in his car driving talking to Dr. Jansen on his cell phone when he swerves to a stop trying to avoid Lana, who is standing in the street. She shatters his windshield with her superpowers and takes him to the plant where she finds out that he is tracking aliens. Lex believes it is all related and believes she is still obsessed with him.
He points out he hasn't hurt anyone and other aliens are on the way. Lana doesn't believe him and prepares to electrocute him. To stop her, Lex taunted her, claiming that she still loved him and he kissed her. Lana pulled away, chokes him and throws him into a wall, knocking him unconscious but Clark stopped her from completing her revenge.
The two fought and the container with the spaceship liquid and the kryptonite falls out, weakening both Lana and Clark. Clark breaks the vial apart, throwing the liquid away and running an electrical charge through the kryptonite and Lana. This reverses the power transfer and Lana loses her powers.
Lana returns to her surveillance center to find the cameras disabled, and Chloe waiting for her. Once her powers were revoked, Chloe confronted Lana about her behavior. Chloe admitted that she didn't believe Lana was malevolent but gave her a friendly warning that she would not let her hurt Clark.
Their friendship was strained after this and they didn't see much of each other, as they both remained busy with work.
Clark meets with Lana at the barn and she tries to convince him she would never hurt him. She refuses to apologize to going to extremes to protect the person she loves and Clark notes she sounds like Lex. She informed him that she made her own choices and claimed that she kidnapped Lionel because she was protecting Clark.
Lana notes that even Clark must have crossed a moral line at some point to protect someone he loves.
Clark says he is responsible for the situation, due to all the secrets he kept from her and now she can't trust him. Lana insists on living with the decisions that she's made and says that she needs to know he loves her no matter what. Clark doesn't reply.
