"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.[1] 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.[2] 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.

SuperBlahBlahAdded by SuperBlahBlah

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)

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)

TG90Added by TG90

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)


"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.[3] 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.[4]

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.[5] She also wanted a rematch with her after having fought and lost in the Daily Planet.[6]

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.

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:

Tess' dreams indicate her obsession with Lex.
TG90Added by TG90

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.
TG90Added by TG90

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 AbilitiesEdit

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.

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.

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.

TG90Added by TG90
  • 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 lifeEdit

Lionel leaves Lutessa at Granny Goodness' orphanage
SuperBlahBlahAdded by SuperBlahBlah

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.

RoR-ElAdded by RoR-El

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.

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.

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.

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.

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.

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.

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.

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".

In the ComicsEdit

Lena Luthor

TG90Added by TG90

In Silver Age continuity, Lena is Lex Luthor's younger sister. After Lex began his villainous career, his family changed their last name in shame to the anagram "Thorul". As a result, Lena never knew she had an older brother, as Lex Luthor himself worked to keep her from learning the truth. Lena had psychic/empathic abilities, gained from touching a space brain, Luthor was experimenting on before he became a villain. She lost her powers after brain surgery, and the decision was made to tell her the truth about Luthor. After the initial shock, there were signs of reconciliation after Luthor discovered he had unwittingly aided another criminal's conspiracy against Lena, and he was deeply apologetic. Lena later married a man named Jeff Colby with whom she had a son, Val. Like many minor characters, Lena as Lex' biological sister was removed from comic continuity following the event of the Crisis on Infinite Earths.

In Final Crisis, Legionnaires Polar Boy, Wildfire, and Dawnstar travel to Smallville during the 20th century, back to when Superman was still a suburban legend. The three heroes arrive to the Luthor household, where they hear a young Lex Luthor arguing with his father about his mother and sister, indicating that the Pre-Crisis Lena has been restored to the Post-Crisis continuity. Unlike her Silver Age counterpart, Lena grew up alongside Lex, until he left Smallville. Lex made certain to cover-up his Smallville history, and that included disavowing a connection to his sister. Lena is now an invalid, living in Smallville with her daughter Lori. Recently, Lori made friends with Superboy, but both were shocked to find Luthor on Lori's doorstep, intent on taking control of Superboy again, and claiming he can cure Lena's condition. With Superboy's help, Luthor indeed cures Lena, but he then undoes his cure, claiming he only helped her to prove to Superboy that he could and that so long as Superman lives, he will never reveal how he did it. Currently Lena is under the care of Wayne Enterprise doctors, thanks to Red Robin.

Lena Luthor II.
TG90Added by TG90

Even after the Crisis on Infinite Earths a new Lena was introduce Post Crisis, as the child of Lex Luthor and Contessa Erica Del Portenza. She is named after Lex's foster sister who had been killed by their foster father, Casey Griggs. After Lena's birth, Lex takes advantage of Contessa Erica's wish to be unconscious at child birth by keeping her permanently drugged and unconscious at his corporate headquarters, not wishing to share his daughter's love with anyone else. 

Lena Luthor II (Brainiac-Teen version).
David KaiqueAdded by David Kaique

When Brainiac 13 arrives from the 64th century, the modern Brainiac possesses the infant Lena to escape it. Even after Brainiac leaves Lena's body, Luthor trades her to Braniac 13 for control of the future technology that has transformed Metropolis. Lena returns to visit Lex during the Our Worlds at War crossover, where she has apparently been aged by Brainiac 13. Lena plays a sneaky role during the event, helping Luthor and his allies beat Imperiex by feeding her information, while secretly manipulating events to benefit Brainiac 13. She is ultimately convinced at the end to side with her father. 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 #162Tangent 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 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.

TG90Added by TG90

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.

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.

  • Tess can speak Chinese and knows kick-boxing, aikido and various other forms of martial arts. (Instinct)
  • Oliver first refers to Tess as "Mercy" during his delirium. He continues to do so throughout the show as a playful nickname.[8] This is a note to Mercy Graves, the villain who Tess is based on.
  • A newspaper article reveals that Tess Mercer is 30 years old.[9] This episode aired on March 19, 2009.
  • Tess wears a bracelet that she gave to her best friend and classmate Megan. Megan was killed when the two were kidnapped. Tess wears it in her memory.[10]
  • Tess can appear to go to the highest heights of extreme methods for her questions' answers.
  • Tess has fought against two of Clark's love interests. She fought Lana Lang at the Isis Foundation and fought Lois Lane at the Daily Planet. She lost both times.
  • Tess is one of three women to have fought Green Arrow.[11] The first was Lois Lane and then Lana Lang.[12]
  • 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 has either fought or had a violent moment with every other woman on the opening theme except for Kara Kent. She has fought with Lana, Lois and Chloe, and though she did not fight her, Martha (as the Red Queen) pointed a gun at Tess from behind.
  • Tess' maternal love of Alexander Luthor/Conner Kent mirrors Lillian Luthor's relationship with Lex.
  • The name "Tess" is short for Lutessa, her birth name. Cassidy Freeman originates the role of Lena Luthor, Lex's little sister from the comics (Lena being Tess' middle name) on live-action television.
  • Tess has been romantically involved with two of her brothers. She revealed to her biological brother that she loved him, but it is later cleared that her relationship with Lex was never sexual but more of a mentor-mentee, also at that point of time Tess didn't know that she was Lex's sister. On an alternate Earth, Tess had a romantic relationship with her adopted brother.
  • Tess has interacted with all main characters, except Jonathan, Pete, Whitney, Jason, and Kara. She has interacted with Jimmy off screen. Tess has interacted with the Red Queen (who unbeknownst to her, at the time was Martha, who Tess didn't meet).

  • 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.;[13] and like Lex, she tested Clark to see if he had superpowers.[14]
  • 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.[15]
  • 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.
