"I just wanted to save the world..." - Tess Mercer, Sacrifice

Tess Mercer (born Lutessa Lena Luthor) is Lex Luthor's former protégée and half-sister and Lionel Luthor's illegitimate daughter.

When Lex disappeared during a private expedition to the Arctic, Tess took control of all his projects and business, assuming the role of acting CEO of LuthorCorp and publisher of the Daily Planet. Like her predecessors, she became obsessed with finding the truth about Clark Kent, had her own metahuman agenda and an unusual approach to saving the world.

Supported by the records left by both Luthors, Tess managed to discover Clark's secret and started to see him as a kind of savior, diverting some of her devotion toward him, despite using unconventional methods to prove it. She had very little touch with everyone who knew Clark, including Chloe Sullivan, Lois Lane and her old flame Oliver Queen, who did not have any confidence in her due to being an emissary of the Luthors.

For a long time, Tess was obsessed with maintaining the Luthors' legacy and was totally devoted to Lex, whom she considered a hero, but after discovering that Lex was spying on her, she became very angry and took her revenge on him, merging LuthorCorp with Queen Industries and leaving Lex without resources to continue his life support.

After learning about Clark's secret and guided by voices coming out of the Orb, Tess released the power contained within the Kryptonian device and allowed Major Zod and his army to be reborn on Earth. Thinking that in this way she would be saving the world, Tess helped Zod to achieve all his goals, but not without getting her own ambitions and plans. However, her plans were affected when Tess was summoned by an old organization to which she belonged, and was pushed to go underground to prevent an assassination attempt.

Being rejected by Oliver, Zod and all those she knew, Tess realized that she had lost everything she had in her quest for power and, in an attempt for redemption, faced Zod and tried to stop him, but was severely burned in the process. From her hospital bed, Tess helped Clark use the Book of Rao and apologized for everything she had done. Unable to bear the wounds she had suffered, she died in the hospital, but was mysteriously resurrected, waking in Cadmus Labs, where she found hundreds of Lex clones. Tess started to take care of what appeared to be a young clone of Lex whom she believed she could change, but things started to become more complicated than she expected due to the latent presence of Lex's mind inside the boy, but was able to convince the genetically engineered version of Lex to have a change of heart with Clark's help.

With a second chance to redeem herself, Tess decided to start doing things right and chose to help Clark and Oliver in their fight against crime. Soon, she was able to obtain a place in their team of heroes and given the command of Watchtower. However, her loyalty was ultimately tested after learning that she was Lionel's daughter, consequently making her a Luthor; and her situation was aggravated when she discovered that she had been resurrected to serve Darkseid and dueled against a Lionel Luthor of a parallel world.

After a long struggle against her dark side, Tess finally chose a side in the battlefield and finally was killed by her brother Lex, but not without getting the redemption she longed for by erasing all of Lex's memories and thereby protecting Clark's secret. Thanks to an unexpected property of the Neurotoxine however, her coscience survives inside of Lex's mind and so is later rescued by the team and resurrected in a cybernetic form.

As an artificial intelligence, called Tess 2.0, she succeeds to overcome her obsession for revenge on her brother and rejoins the Justice League, becoming Watchtower once again while Chloe is on maternity leave.

Physical Appearance

Tess in Season Eight.

Tess in Season Ten.

Tess is a Caucasian female in her late twenties. Her height is about 5'8", and her build is thin and moderate. She has fair skin with long curly red hair and green eyes.

Tess usually wore her hair down or straightened, but sometimes had it tied up in a bun when she was working at the Daily Planet or Watchtower. On the occasions when Tess attended social events, she had her hair tied to the side. (Checkmate, Kent)

Unlike most of the main characters, Tess' appearance virtually stayed the same since her first appearance in Season Eight, though her hair was slightly longer in Season Ten. Like her half-brother Lex, Tess usually dressed in dark clothing, wearing mostly purples and blacks. She also had a signature gray, button-down coat that she wore a number of times.

Tess also had a pair of glasses that she wore while working at Watchtower. (Ambush)

Tess' new cyber form after her rebirth.

While she was Lex's secondary consciousness she appeared wearing the clothes that she wore when she was killed. The only difference was that her grey button-down coat's colour was changed to green with a big blood stain on it. (Guardian, Detective, Haunted)

Emil Hamilton's original costume design for Tess.

In her cyber form, Tess appears as an holographic mass of RAM's memory banks and binary codes which forms the red, nude, transparent ghost-like shape of her physique. While her hair and eyes are bright red, her skin seems light red, almost pink with some shades of white. Her whole body emits a bright red light and is surrounded by light particles similar to fireflies. (Haunted, Argo, Olympus, Hollow)

While Emil offered a series of codes which upgrades clothes on her projection interface, she refused stating that clothes are for people and she doesn't see herself as one anymore but she later reconsiders accepting Emil's offer. (Hollow)

Later she adopts a red, transparent, full body costume, which she "wears" on a regular basis. (Alien, Harbinger, Lantern)

Personality

"Tess Mercer, the ultimate eco-terrorist." - Lois Lane about Tess Mercer, Pandora

Tess is a fine example of what can happen to an individual who has been betrayed, abandoned, abused and used by those they loved. While being the meek Tess that Oliver dated, and rescued from the island, she trained herself to become strong, independent, and fierce in her life as well to everyone.

Tess cares deeply for the Earth and nature. She believes that humankind is destroying the planet Earth, and that the Kryptonian race is the solution. She believes this because she feels a strong responsibility to make things right, it takes her time to realize that Clark is destined to save Earth and he will do it on his own terms.

Based on this conviction, when she read about the Traveler in the Luthor journals, she believed it was her role to help him become a hero and battle the ultimate Destroyer. Still unsure of Clark's role, she later believes that Major Zod would help save humanity, which is why she released him and his fellow Kandorians from the Orb. (Crossfire) Tess gradually became more conscientious, both as a result of seeing her actions in relation to Zod backfire, and also because of her interaction with Clark, Oliver, and their allies. She gradually became someone that the Justice League could trust, culminating with her taking over the role of Watchtower from Chloe in Season 10.

Tess strives to be on equal terms with her partners, from her professional interactions with Lex Luthor to her attempts to save humanity with Clark Kent and Zod. This may be the result of her brutal treatment at the hands of others: she was physically abused by her father, held hostage by Marcos, and controlled by Lex. In the past she does not hesitate to manipulate people or use unconventional methods to get what she wants. She is willing to go to great lengths to achieve her goals: she even allowed herself to be brutally interrogated by the Kandorian army in order to learn more about the Kandorians.

Tess respects strength and power. She gave Lois a raise despite the fact that Lois always gets in her plans and has hostile encounters with her. She also wanted a rematch with her after having fought and lost in the Daily Planet.

Tess appears to be cold on the outside, but on several occasions she has been seen crying alone. (Identity)

Tess is capable of great brutality and violence, especially vengeance or if she feels that it is for the greater good. As her character progresses we can see the changes her personality on-goes as she repeatedly claims that Clark has saved her and she becomes more creative in methods to help others. This can be seen in how she treats Lex in the final episode, instead of killing him she gives him another chance to live without the horrible memories that made him a monster.

• Tess personally poisoned her old kidnapper Marcos dooming him to an almost certain death, after purposefully bailing him out of jail.
• She was deeply upset and filled with vindictive rage against Lex when she discovered that he had been spying on her through ocular implants. To get revenge, she merged LuthorCorp with Queen Industries and left Lex without resources to continue managing his projects of life support hoping to kill him with it.
• Tess also brutally beat and killed Regan Matthews.
• She also attempted to kill Lana Lang and Dr. Groll, in an attempt to destroy Lex's Project Prometheus.
• Tess blew up Davis Bloome in his car after discovering he was a serial killer.
• Tess had Parasite take Livewire's superpowers away, and then killed Livewire.
• Tess shot Winslow Schott in the leg without remorse, forcing him to leave Oliver Queen alone.
• Tess overpowered or killed the Kandorian security guard that Major Zod had sent to interrogate.
• Tess shot Stuart Campbell after he refused to wipe Lois Lane's memories.

Eventually, Tess started to try and redeem herself for her sins. From this point on, she used violence only when she didn't have another choice:

• She tried to stop Zod and beat him with Kryptonite knuckles, only to have her face severely burned by his heat vision.
• As her first mercy killing, Tess tried to inject Alexander Luthor with cyanide to prevent him from becoming the villain he will eventually loathe being. However, the syringe had bent due to his impenetrable skin.
• Tess used a chemical solution from Summerholt to destroy all of Lex Luthor's memories of his time in Smallville.

Tess' dreams indicate her obsession with Lex.

Having moved on with her life and changed her personality, due to her friendship with Clark and her involvement with the Justice League, she still seems she hasn't forgive Lex for what he had done to her for all these years: manipulated and lied to her, used her as his own "ears and eyes" without her will, kept her in the dark about her origin, killed her and finally threatened her if she would not tell him the truth about Superman. Even when she was freed from Lex's body she still seemed to hold on to her past seeking vengeance from her brother. While she was on standby mode she dreamed about many moments in her life and between them they were many scenes of violence including Lex, indicating that she wants to get revenge. In many cases she has being seen to uses her powers as A.I. to somehow hurt or even kill him. This obsession to get revenge on Lex seems to stops her from settling into her new life and moving forward.

Tess also seems to acknowledge her obsession for revege, asking for some advice from Hank Henshaw, who has been in her place some months ago. According to Henshaw, recognizing her obsession as a problem and asking for help makes Tess move a step forward. Later Tess actually got her chance for revenge on Lex but at the last moment, she decided to spare her brother's life. She said, she feels like she is getting a second chance and she does not want to ruin it with any blood on her hands or darkness in her heart and that is why she didn't kill him.

Tess rejecting her human side.

Even though Tess was grateful to her friends for freeing her from her brother's body, she was unsatisfied with her new state as an A.I. at first. She rejected Emil's offer to design a costume for her because, according to her, clothes are only for humans and she didn't considered herself as one anymore. Tess seemed to have distanced herself from her humanity and her life, focusing only on her work at the Watchtower and especially her revenge on Lex. She was overlooking any signs that proved she was still human, at least in part, like the fact that she was still able to dream, because of her frustration over Lex. Fortunately when she finally faced Lex she chose not to kill him, realizing that she still has feelings. She confessed to Emil Hamilton that the reason for not killing Lex was because of her dreams, stating that if she has dreams, it must means that she is not just a machine but more human than she previously thought. She then started seeing her current state as a second chance and not as a bad fortune, wanting to make the best of it and that is why she decided to finally accept Emil's offer. (Hollow)

Powers and Abilities

Tess possesses no superhuman abilities, however due to conditioning and practice, she is good at:

• Diving: Though by no means an expert, Tess has stated that she enjoys diving as a hobby in her spare time. (Toxic)
• Kickboxing: Tess Mercer keeps herself in top form and is maintains a regular exercise regime while also practicing kick-boxing techniques. (Instinct)
• Hand-to-hand combat: Tess has being seen to be able to battle many skilled people in a hand to hand combat and most of the times she wins without needing to use a weapon to do it.

Tess waking from her standby mode.

As an artificial intelligence, Tess is able to manifest some abilities mostly associated with Watchtower's technology systems. Tess, in her new form, has many characteristics of a computer system substituting those of a human, like instead of going to sleep she goes on a standby mode, although it is stated that she may dream while she is on standby. Her thoughts also appear as options on screen.

Tess takes control of a robot.

• Technology Interface: She had been able to control the doors at LexCorp, remotely locking them whenever she wanted and manipulate some information through the computer systems at Metropolis' hospital, meaning that her control over technological systems does not end within Watchtower's walls. She has also being able to watch through cameras placed in almost every building in the city.
• Electronic Manipulation: Tess is connected with almost all the city's computers and prove to be able to control any electrical object anywhere. She took command of a helicopter and a crane arm in Metropolis and a robot at S.T.A.R. Labs.

Tess creates a holograph of a neighbourhood in Metropolis.

• Holographic Projection: She also has the ability to move from a place to another through the system in seconds and appear as an hologram through projectors, which are at some certain places. This is may possible due to Tess being connected to the network of the place she wants to go. She is also able to create on her own holographs of other objects.
• Longevity: Since Tess is an A. I., she is incapable of aging.

Early life

Lionel leaves Lutessa at Granny Goodness' orphanage

Born as Lutessa Lena Luthor from an affair between Lionel Luthor and Pamela Jenkins, she was given up to the St. Louise's orphanage, run by Granny Goodness. Granny Goodness began training Lutessa to become the leader of her group of warrior women due to the great potential she saw in her and considered Lutessa as her favorite. Because of the abuse she received during the training, Lutessa had a hard time in the orphanage and tried to escape on one occasion using a key hidden in her room. However, Goodness discovered and stopped her.

Lutessa being dragged away by Granny Goodness

Granny Goodness removed all of Lutessa's memories about her birth parents and childhood so far, but when Lionel located a home for his daughter and threatened Goodness to close the orphanage down if Granny resisted, she complied and removed Lutessa's memories of the orphanage before sending her at age five to her new parents. She was adopted by the childless Mercers in Louisiana and renamed "Tess Mercer".

However, her new life was far from content. Tess grew up in a swamp house where she taught herself how to read. Tess was abused by her adopted father when she was young, and often envied those that had such "blissful" childhoods. At the time, she ended up with a ruptured eardrum and a thrice-broken arm. However, she got into Harvard at fifteen and graduated from college at the age of 17 as a marine biologist.

Tess and Oliver meet for the first time.

Tess found Oliver Queen on an island in the South Pacific where she and her friend were kidnapped while on a marine biology trip. Oliver was poisoned by a flower on the island, but Tess saved his life due to the fact she was an expert on that field. He then returned the favor by saving her life using a makeshift dart (from the poison from the indigenous plant) against their kidnapper before they left him for dead and set sail for Star City.

After some time, Tess began working for LuthorCorp and a month after started, she was recruited by Amanda Waller to be part of a secret government organization called Checkmate. Amanda recruited her in order to learn more about the research on aliens from Lex Luthor and kept Tess as an undercover agent, placing her as the best candidate to win the confidence of Lex.

Tess kidnaps Lana Lang

While gathering viruses for LuthorCorp (possibly during Project Mercury) when Brainiac attacked, Lex saved Tess from an explosion that Brainiac caused. However, it was at that time during her recovery that Lex implanted a nano-transmitter in her optic nerve, so that she could be “Lex's eyes and ears” in case he needed her in the future.

In 2008, Tess was ordered by Lex Luthor to kidnap Lana Lang and to force her to create a farewell videotape to Clark before transporting her to a secret facility for her own safety. She was reassured by Lex that it was for her own safety and that the coma that Lana had been in was because of Clark Kent.

Season Eight

"One of the most important things that Lex taught me is you can't afford to live in the past." Tess Mercer to Oliver Queen, Committed

Tess introduces herself at the Arctic tundra.

Four weeks after Lex Luthor disappeared, Tess went to the Arctic to take command of LuthorCorp and search for signs of their missing CEO. She turned out to be the successor designated by Lex to guard all his interests in case something happen to him and immediately took control of the search project, but was forced to leave the area when they were ambushed by Oliver's team. She then made her way to Smallville to take up residence at Lex's mansion and in the process had her first encounter with Lois Lane. Tess began to look insistently at clues about the Lex's whereabouts and finally ended with a box containing the Crystal of Knowledge and a photo of a footprint that does not belong to Lex.

Clark saves Tess.

Tess took possession of all Lex's business, including the Daily Planet and on her first day, she was saved from the burning remains of a bus explosion by her new employee, Clark Kent. After she introduced herself to him, Tess showed herself to be flattered for meeting him, revealing that Lex told her a lot about Clark.

It became apparent that it was no coincidence that Tess was in the bus at the time of accident because she was chasing a girl with metahuman powers to recruit her for her new team of heroes that she was putting together and finally intercepted the prison bus in which the girl was put after Clark caught her.

Tess is questioned by Oliver about how she became the Luthor Queen.

After Oliver falls poisoned mysteriously, it was revealed that Tess and Oliver knew each other from before and that the two had maintained a relationship in the past. Tess helped to cure Oliver and later he questioned her about how much she had changed and about her alliance with Lex. Tess showed continuing resentment towards him for having cheated her, but however revealed to him that Lionel killed Oliver's parents.

Tess tests the crystal.

During her research about the crystal she found in the Arctic, Tess tracked down one of Lex's scientist for help and was reluctant to believe that the crystal was an alien technology, but when an experiment on it, sent a beacon attracting an alien princess to Earth, she began to believe it. After the crystal was stolen, Tess became suspicious of everyone who knew about it and later received an email saying that she wasn't ready yet.

At the same time, Oliver tried to rekindle his relationship with Tess and invited her to dinner but however, despite sleeping together, Tess told Oliver that she was not interested in a romantic relationship and rejected him.

Tess uses Sebastian to help her find the crystal.

Tess continued her recruitment of special people and her search to find out who took the crystal from her. She hired Sebastian Kane to help her find it by questioning Lois since she was her prime suspect and also sent her men after Jimmy, as he was her second suspect.

Tess tells Clark about the footprint in the Arctic.

When the crystal was eventually used, Tess tracked its energy pulse reading to the Kent Farm, where she questioned Chloe about it and started to suspect more of her and Clark. After meeting Faora while she was possessing Lois and learning a bit about Krypton and Kal-El, she called Clark into her office and revealed to him that she knows he was the last person to see Lex alive.

Finally, it was revealed that Tess had made contact with Lex at some point after her arrival in Smallville and that she had been keeping in touch with him through emails.

Tess learns the truth about Lex.

After Lana Lang returned to town, Tess was approached by her and confronted with the knowledge that Lex was alive and that Tess knew where he was. Tess denied that statement and after she learned that Lana had stolen information about a secret survival project of Lex denominated Project Prometheus, she confronted Lana and started a fight. Lana won the battle and exposed to Tess the nano-transmitter that Lex implanted in her optic nerves. Feeling betrayed, Tess decided to repay Lex by closing his bank accounts and offered Oliver the chance to merge with LuthorCorp.

Tess ready to destroy the Project Prometheus

When Lana went missing, Tess revealed to Clark everything that happened to Lana after awakening from her alien coma. After being confronted by Lex's right-hand man, Regan Matthews, who was revealed to know about the transmitters in her eyes, they got into a fight and Tess managed to killed him. Keen to prevent Lex from getting his hands on the Prometheus suit, Tess tracked it down to Dr. Groll's laboratory and was prepared to kill Lana in order to destroy the suit. However, Lana managed to defeat her and then tried to convince Tess to let go of her desire for vengeance against Lex.

Lex tried to get his revenge on Tess and the other LuthorCorp board members for switching their allegiance to Oliver Queen by hiring Winslow Schott to set a bomb to kill them. However, Tess was out of town to see a surgeon to remove the nano-technology that Lex had inflicted her with.

Tess sets up the fake plane crash.

After returning to town, Tess started to become more suspicious about Clark´s secret and devised a plan to force Clark to expose his powers aboard a jet, and even confided to Clark her deepest secret hoping that in return Clark would reveal his secret to her, but her plan was not successful. After they returned to Smallville, she thanked him for saving her and tried to convince him that he could trust her, stating she isn't Lex.

Tess finally managed to get hold of Lionel's journal and by reading it, surmised that two Kryptonian boys fell to Earth on the day of the meteor shower and soon came to the conclusion that Clark was the one who Lionel called "The Traveler".

Tess tries to discover more about Davis after trying to kill him

Thanks to Jimmy's note, Tess discovered that Davis Bloome was killing criminals and realized that he was the other Kryptonian and attempted to kill him although he survived and then she took him back to the mansion to explore his past with the Luthors. Tess confessed that she believed that Clark and Davis were destined to kill each other and keen for Clark to embrace his destiny but he ignored her.

It was revealed that Tess was in possession of the Kryptonian Orb that Lex deposited in the console of the Fortress the last time and following Clark's refusal to accept his destiny, Tess began to publish articles revealing Davis as the serial killer and began a manhunt against him, knowing that many will die in the process.

Tess listens to the Orb.

Still keen to defeat the threat of Doomsday, Tess found the perfect opportunity to use her team of heroes and sent them after Chloe and Davis, who were on the run. Tess sent her shape-shifting assistant, Eva Greer, to infiltrate Clark's life disguised as Chloe to learned more about him and using the recovered Kryptonian information relayed from Eva, find and destroy the Black crystal to force Clark to confront his destiny and kill Doomsday.

Tess prevents Lois from leaving.

It was revealed that Tess had been taking orders from the Orb who tells her that she will be the savior of Kandor after Clark kills the beast and when Tess returned to the Luthor Mansion after work, she found the Orb missing and that the vault was busted open from the inside and then instructed all of her staff to find it. When Tess discovered that Lois had been in her office, she immediately suspected her and confronted Lois at the Daily Planet basement. Lois accuses Tess of trying to bring an alien nation to conquer Earth but Tess claims she only wanted to save the world. A fight is quickly developed and Lois managed to defeat Tess by knocking her out.

Tess sees the Orb activate.

Tess woke up and returned to the Luthor Mansion and after Doomsday was defeated, Tess saw a glowing light outside the mansion. As she approached it she saw the Orb send a burst of light into the ground, out of which came a man standing on the Mark of Zod.

Season Nine

"Because I see... I see what mankind is doing to this planet. The earth is doomed." - Tess Mercer to Jor-El, Kandor

Tess being held hostage by the Kandorians.

Having released Zod and his troops via the Orb, Tess was held prisoner for three weeks in the Luthor Mansion. During this time, she was savagely interrogated by the soldiers and after meeting their leader, General Zod, she discovered that the Kandorians did not know how they came to be on Earth and that they are powerless.

When suddenly the whole army left the mansion, Tess revealed that letting herself be caught was only part of her plan to discovered more about them.

Tess discovers the Kandorian's secret lab.

Tess started her search of Zod and his troops, which led her to an abandoned laboratory with stolen technology from LuthorCorp. Tess realized that the kryptonians were trying to get their powers in any possible way and after Tess's team recovered the remains of the kryptonian experiment, they revealed to her that Kryptonian symbols had appeared across the globe since the day that Zod arrived on the mansion. Tess then saw the House of El symbol in a picture and someone lying on it.

During her search, Tess investigated the disappearance of twelve sailors on a Luthorcorp facility until was attacked by rabid zombies that infected her with a strange virus. When Clark and Lois visited her to ask what had happened she aggressively attacked them turned into a zombie and was placed in quarantine to be studied in detail, as the doctors believed she was the center of the infection.

Tess investigate the kryptonian symbols around the world

After being cured, Tess tracked Oliver down to Mexico and had him brought back to a shareholder's meeting in Metropolis at the Ace of Clubs. She made a "deal" with Toyman at his prison cell by giving him Metallo's kryptonite heart and enlisted him to discover how it worked.

Zod surprises Tess at the Luthor Mansion.

As Tess displayed her twin solar tower to her meeting of LuthorCorp executives, she was ambushed by Zod, who congratulated her on her accomplishment. When Zod asked her to help him find the "Blur", she denied any information about knowing who it was. However, she did ask him for equal partnership, but he told her that no human would ever stand with a Kandorian. Not trusting Tess, Zod sent a soldier to kill her but instead she killed the soldier and returned his medallion to Zod, letting him know she is a force to be reckoned with.

Tess accepts Zod's proposal.

Finally, Tess and Zod formed an alliance, although her primary motivation was to prevent Zod from finding the "Blur." Tess kidnapped Jor-El and convinced him to tell Zod that he was the Blur so that Clark could continue saving the world and when Clark learned that Tess had imprisoned his father, he threatened her by grabbing her neck and forced her to tell him where Jor-El was. She was happy that Clark had finally revealed his powers to her but not the way she expected. When she showed the location of Jor-El, Clark realized that Tess let Jor-El be kidnapped so that she could discover where the Kandorian army was.

Tess sees the future.

Intrigued by the mysterious disappearance of Lois weeks ago, Tess kidnapped her in order to examine her memories of the missing three weeks. Tess requested the use of Summerholt technology to enter Lois's mind and saw the Solar Tower completed, realizing Lois was in the future. Tess connected her mind to Lois's mind and after discovering that she will be killed by Chloe, Tess began to question her allegiance to Zod.

One night, Tess went to her office at the Daily Planet and was shocked to find a chess-set piece on her desk. Tess then met with Amanda Waller at the Checkmate headquarters, who addressed her as "Agent Mercer" and said they had a lot to catch up on.

Tess is revealed to be a member of Checkmate.

With the solar tower near completion, Zod decided to terminate his relationship with Tess and threatened to kill her. Then Tess tried to enlist Chloe´s help and suggested that they work together to stop Zod but, when Chloe refused. A Gemstone-kryptonite-infected Clark wanted to get his revenge on Tess for killing Jor-El and Tess pleaded with him for her life, saying that she did not kill Jor-El and reminded him that she had not revealed his secret to anyone. Chloe saved Tess and later Clark learned that Tess was telling the truth.

Tess pleads for her life.

Tess angrily confronted Oliver about the destruction of her Solar Tower and embezzlement that she discovered within the company. She sent an agent to follow Oliver and discovered that he and Chloe had an arsenal of weapons. However, before she was able to get to them, Oliver had hidden them.

Tess about to kiss Zod.

Tess arranged a meeting with Zod at the Kent farmhouse, where she shot him to prove that he had powers. She used green Kryptonite to weaken him and after talking of the superiority that some have over others they end up kissing and in bed. Zod asked Tess how she had weakened him in the barn and she told him they both have their secrets.

After Tess was summoned for a Checkmate operation to capture Green Arrow and later blamed when Green Arrow escaped, Amanda Waller threatened to kill her if she did not sort out the problem. When Tess discovered that Oliver was actually Green Arrow and helped him and Clark to shut down the power at Castle so they can save "Watchtower", Tess plead with him for help but Oliver showed no sympathy for Tess, as his trust in her had ended. Tess then revealed that she is "going underground", to prevent an assassination attempt from Checkmate

Tess resurfaced to retrieve John Corben when he escaped, and was discovered by Chloe who wanted to discovered how Clark became infected with red kryptonite. Together, they used their resources to stop Clark and Zod new partnership sending Corben to the Fortress of Solitude and as a desperate attempt to win support, Tess tries to manipulate Zod and informed him of some of the Kandorians betraying him to serve Kal-El, saying that she was the only one he could trust.

Chloe warned Tess about her decisions

Tess returned to LuthorCorp only to find Chloe in Oliver´s office, hacking into the Swiss National Bank. She reminded Chloe that although she might be underground, she still ran Luthorcorp. The pair discussed Tess's alliance with the Kandorian army and Chloe commented on Tess's partnership with Zod, telling Tess that she'll run out of people to betray quickly and warned her about her decisions.

Tess is resurrected by Chloe.

Tess came to the conclusion that Chloe was Watchtower and went after her, demanding all the information she possessed about the Kandorians. However, the two become trapped inside the building after the security system was activated by a Checkmate's protocol to access the system and both had to work together to try to escape alive. Tess revealed she has a GPS strip in her flesh that allows them to hack the computers and that burrows deeper into its host when threatened with extraction. In the midst of a touching conversation, Tess opens herself to Chloe and advises her about her relationship with Oliver. After making their way to get out of Watchtower, the two headed to Metropolis General Hospital knowing that Checkmate was following them to try to shut off the GPS strip. Chloe tells her the only way was killing her, and Tess accepted and put her trust in Chloe, knowing that she would let her die. After deactivating the chip, Chloe resurrected Tess, much to her surprise, and Tess then agreed to keep Chloe's secret as a form of compensation.

Tess revealed had the Book of Rao.

While being held hostage by Maxwell Lord using his telepathic abilities, Tess was accused of being the Red Queen and was required to disclose the location of the Book of Rao. However Tess escaped and went to find the Book of Rao she stole and hid in the wine cellar. Tess was later approached by the Red Queen, who was actually Martha Kent, and was forced to hand over the disc to her. Martha warned Tess about the bad choices she has made in her life and threatened her to stay away from Clark.

Tess confronts Zod looking for redemption.

When Zod declared the war to the earth, Tess revealed she used a tracking device on John Corben to find the Fortress of Solitude and visited it, where Zod was trying to mess with the console. Looking for redemption for everything she had done, she attacked Zod with kryptonite brass knuckles and damaged his face. However, Zod managed to heal and attacked her with heat vision, burning half of her body.

Tess dies.

Clark found her and rushed her to the hospital, where she told Clark about the crystal console the Kandorians built and how he could use it to activate the Book of Rao as her last chance for redemption. Later, she had a violent attack from her injuries, resulting in her death.

Once the doctors pronounced it and left the room, a mysterious old woman entered the room, shutting the door behind her.

"You want to know the truly perverse part? I'm upset that he threw me away... As grotesque and sordid a family tree as I've just inherited, I... Wasn't good enough." - Tess Mercer to Clark Kent, Luthor

Tess in Cadmus Labs.

Tess awakened in Cadmus Labs, mysteriously returned to life, with her face completely healed. She met "Alexander" (a conscious pre-pubescent clone of Lex), who told her how she survived. Tess discovered a multitude of clones engineered from Lex's DNA, and accidentally released an older psychotic clone, who incapacitated and imprisoned her in the facility, knowing that Clark would soon come to rescue her. When Clark eventually appeared, Tess relayed the clone's message to meet at Riley Field and later, when she returned to the Luthor Mansion, she took "Alexander" to live with her.

At the end of the crossover, Brainiac 12 and Imperiex are both destroyed, and Lena is regressed to infanthood and returned by her father by, who tells Luthor that he now has a second chance to try to be a man instead of a god.

Following Our Worlds At War, Lena appears infrequently, sometimes shown as still Brainiac discs on her forehead. In the Superman's Metropolis miniseries, the artificial intelligence controlling the B-13 technology believes itself to be Lena Luthor. When it creates a human body (female, but bald) to pursue a romantic romantic relationship with Jimmy Olsen, Superman confronts her with the real Lena Luthor, making her realize her personality is a computer simulation of Lena's. Lena has not appeared since Luthor lost the presidency, and her current status is unknown.

Alternate versions of Lena Thorul also appear in Superman Vol 1 #162, Tangent Comics: Wonder Woman #1 and Supergirl: Cosmic Adventures in the 8th Grade.

In the New 52's title Forever Evil, Lex Luthor mentions that when he was a child he tried to save his sister's cat, which had gotten itself stuck up an old white oak. According to him, Lena's incessant pleading motivated him to the rescue but when the cat scratched Lex, he threw it into the river. At some point later, Lex mentions that he used to run when older kids would chase him and his sister, calling them names and holding them in contempt for their father's reputation and sometimes they weren't fast enough so Lex would stop and tell to his sister to keep running, to hide in the field until it was over. 

Mercy Graves

Mercy Graves as she appears in the comics.

Mercy first appears in the DC Universe comics during the No Man's Land storyline. She is later joined by another female bodyguard in Luthor's employ: Hope Taya. The two might be Amazons, as they have exchanged blows with Superman. When the sorceress Circe appears at the White House demanding to meet with Lex. Hope and Mercy inform Circe that they can always recognize her, no matter what disguise or form she might take, suggesting the kind of previous familiarity which Amazons might possess. After temporarily changing them into birds, Circe tells Lex that he will need to rehire new Amazon bodyguards.

Although Hope's time as a LexCorp employee has passed, Mercy can be seen with the fugitive Lex Luthor after he is driven from the Presidency. Despite her loyalty to Luthor, she has still shown some humanity even while in his employ; when Superman was searching for Lois Lane after she was abducted and impersonated by the Parasite, Mercy saw him during his search, and, in that moment, saw him not as an alien, but as a man who had lost everything.

In the series 52, Mercy is seen alongside Luthor at the unveiling of his "Be Your Own Hero" program, and is injured when she fires several gunshots at Steel, which he deflects and sends back at her, hitting her in the right hand. She is later shown in Luthor's employ in 52 Week 40.

Mercy later appears in the Infinity, Inc. series, apparently wanting to atone for her past deeds. She takes on the moniker "Vanilla", and wears a costume equipped with a special mask, that will keep her identity hidden from the likes of Superman and Lex Luthor. Mercy almost beats a man to death. She leaves the team soon after, accepting the fact that she isn't "hero" material.

Mercy's status as an Amazon is confirmed when the supervillain Prometheus nearly kills Supergirl with god-forged bullets he claimed he bought from her.

Mercy also made some appearances in the comic book tie-in of the video game DC Universe Online and the comic book tie-in of the animated TV series, Young Justice, again as Lex's henchwoman.

Eve Teschmacher

On Earth-30, during the Superman: Red Son storyline, she made a cameo as Lex Luthor's secretary when Lex complains to her regarding Brainiac's inability to read a common road map.

She also appeared in JLA: Earth 2 when Alexander Luthor Sr. was filling in as the Matter Universe's Lex, and she was briefly seen working at LexCorp after Superman discovered Alexander's intentions to bring down the Crime Syndicade of America. Alexander then deposited 80.000 dollars in her account and told her to take a nice vacation somewhere warm.

She also appeared in Superman Returns Prequel #3, the comic book tie-in of the film with the same name.

She has appeared in Superman Family Adventures, which is a comic series for younger-readers, again next to Lex Luthor. In the last issue of the series Eve shares a scene with Lex, which is a nod to a scene from the film Superman Returns, where Lex shoots a kryptonian crystal in the ocean.

• Since the introduction of her character, it was unknown if Tess ever met Lionel Luthor. However, Tess remembers the night, when she was a young girl, that her real father placed her in the care of Granny Goodness. Tess was able to obtain her "Certificate of Live Birth" from Saint Louise's Orphanage in Metropolis revealing that Lionel Luthor and Pamela Jenkins were her biological parents. Tess' real birthdate is November 12, 1981 and her birth name is Lutessa Lena Luthor, making her 30 years old at the age of her death, one year shy of her older brother Lex Luthor.
• Tess was the first person that Oliver Queen has saved in his life, but not before Tess saved his life after he had been poisoned.
• St. Louise's Orphanage where she grew up was filmed on the same set as Black Creek, but in Black and White.
• Tess is the only CEO of LuthorCorp to not go to jail or prison unlike Lex's arrest and Lionel's arrest. Although Clark was planning to turn Tess over to the Metropolis Police Department for implanting chips in Bette Sans Souci and Rudy Jones and for the murders of Leslie Willis, Eva Greer and Neutron, but failed.

• Tess' maternal love of Alexander Luthor/Conner Kent mirrors Lillian Luthor's relationship with Lex.

Notes

Miss Eve Teschmacher

Mercy Graves

• Tess's name is inspired by Miss Eve Teschmacher (the loyal assistant of Lex from the 1978 Superman film played by the actress Valerie Perrine) and Mercy Graves (the loyal assistant of Lex from Superman: The Animated Series voiced by the actress Lisa Edelstein).
• Tess is a combination character, created through an amalgamation of Lena Luthor, Mercy Graves and Eve Teschmacher.
• This is the second live action appearance of Lena Luthor. She first appeared in the live action TV show, Superboy, where she was portrayed by the actress Denise Gossett and Jennifer Hawkins who played Lena in a younger age.
• Even though Lena Luthor never appeared in any animated series, in an episode of Justice League Unlimited animated series titled "The Clash", as Superman and Captain Marvel crash into the buildings of Lexor City (Lex Luthor's city), one of the buildings bears the name "Lena Luthor Memorial Hospital".
• In the TV series Superboy, Lex Luthor's assistant who was hepling him in his mad schemes was a character named Darla. She was an original creation for the series, but like many other female characters who have been Lex's right hand, she had many common elements with Miss Teschmacher.
• Eve Teschmacher and Otis serve as Lex Luthor's most loyal accomplices in his crimes in the Superman films, for which both characters were originally created for. Even though she did not appear in the homage sequel of the Superman films, titled Superman Returns, she along with Otis appeared in the comic book tie-in of the film.
• In the movie Superman Returns, Lex Luthor's loyal assistant was a woman named Kitty Kowalski, she served as a prison nurse and would give Lex his examinations. The character was entirely different from Tess Mercer. She is based mostly on Eve Teschmacher, whom she replaced, one of the characters Tess is based on. 
• In the comics one of the last female characters who served Lex Luthor as his right hand women was Lois Lane Robot, a robot who looks exactly like Lois Lane. This character may have influnced the creators of the popular animated show Young Justice to create a new version of Mercy Graves who is a cyborg. The fact that Tess is now an A.I. indicates that the creator of Smallville: Season Eleven was also influnced by that character. In the New 52, the two female characters who appear to serve Lex Luthor as his accomplices are also both robots.
• In the comics, Granny Goodness has a dog named "Mercy". Tess shares the same nickname on the show.
• Tess has common grounds with the comic character Big Barda. Both managed to escape the Granny Goodness' team of fighting women and both were considered Granny Goodness' favorite and best pupils.
• In the comics Lena Luthor has also appeared as a mother. Pre-crisis Lena had a daughter, named Nasthalthia "Nasty" Luthor, with an unnamed European man. She appears in the non-canon mini series All Star Superman as Lex's protégée. Post-crisis Lena has a daughter named Lori Luthor with whom she lives in Smallville. Lori grew up with her invalid mom and her distant dad so she always had to take care of Lena. She also befriends Superboy and she finds out his real identity but does not reveales to him that she knows.
• Tess taking care of Connor and living with him on Smallville, even for a small time of period, mirrors Lena Luthor's last comic appearance in the pages of the Superboy series where Lena lives with her daughter Lori in Smallville. In that storyline Conner Kent develops a close relationship with both mother and daughter.
• The storyline of season 10, where Tess is turned from a villain into a hero, a member of the Justice League called Watchtower II, is similar with a storyline from the comics, where Mercy Graves leaves Lex Luthor and becomes a member of the superhero team, Infinity Inc., and is called Vanilla.
• Tess being killed by Lex in the LuthorCorp office is similar with a scene from the animated movie Superman: Doomsday in which Lex kills Mercy Graves, one of the characters Tess Mercer is based on.
• A Mercy Graves-like character named Misty was to appear in the unfinished film Superman Lives. Not unlike her counterparts from the DC animated universe and comics, she is the valet/bodyguard/lover of Lex Luthor. She is by Luthor's side all through the film during his alliance with Brainiac. Interestingly, in several drafts of the script, she does not appear to say a single word (like many versions of Mercy in other media).
• Granny Goodness explains that Tess was born in darkness which is proven by being the heir of Lionel Luthor, raised by Granny Goodness and abusive parents, and being the sister of Lex Luthor.
• Lex chose Tess to be his successor to his estate before he left for the Arctic Circle in case he never returned from his own personal destiny.
• Tess inherited Lex and Lionel's obsession with the Traveler. Like Lionel, she wanted to help Clark fulfill his destiny.; and like Lex, she tested Clark to see if he had superpowers.
• After Lex had saved Tess's life, she had fallen in love with him and would've done anything for him but at the time she didn't know Lex was her half-brother.
• Tess doesn't share any scenes with Jimmy Olsen during Season Eight.
• Tess is the only main character who was an antagonist but was never a main antagonist for any season of Smallville. However, her good and evil status is up for some debate, as she often uses unscrupulous means to help Clark that do not always line up with his more purist view of justice.
• With the revelation that Tess' biological parents are Lionel Luthor and Pamela Jenkins, Tess becomes the latest Smallville main character to be an orphan. Other orphaned main characters include Clark Kent, Oliver Queen, Lana Lang, and Davis Bloome.
• It's unknown why Lionel abandoned her and left her to be adopted. It is possible he wanted to salvage his marriage. Or like his third son Lucas, Lionel wanted to see how she fared on her own without his money or influence.
• When Tess sings, Cassidy Freeman uses her natural singing voice.
• Like her brother Lucas, she is the only Luthor sibling to not have a clone.
• Tess has died 4 times. She is shot by Chloe, electrocuted by Chloe, burned by Zod and her final death came at the hands of Lex.
• Tess was the seventh and last main character to die. She is also the first and only female main character to die.
• Clark is the only main character to find out that Tess is a Luthor. Six months after Finale, the truth about Lex and Tess being siblings has been revealed to the public. While it is never shown on-screen, Lois makes a vague reference in Scion to Tess being a part of the Luthor family, suggesting that she does know the truth. Also, while not a main character, Emil Hamilton clearly knows the truth as well, as when talking to Tess in Kent he refers to Lionel as her father.
