Smallville is an American television series developed by writer/producers Alfred Gough and Miles Millar, and was initially broadcast by The WB. After its fifth season, the WB and UPN merged to form The CW, which is the current broadcaster for the show in the United States. The show features a regular cast of characters, which began with eight main characters in its first season. Since then, characters from that first season have left the show, with new main characters having been both written in and out of the series. In addition, Smallville features guest stars each week, as well as recurring guests that take part in mini story arcs that span a portion of a season. Occasionally, the recurring guest storylines will span multiple seasons.

The plot follows a young Clark Kent, in the fictional town of Smallville, Kansas, as he journeys toward becoming Superman; it also follows Lex Luthor's path to the dark side, and the two's friendship turned hatred for one another. As the series progressed, recurring guests are added to help move the overall storyline of the show, like the addition of the disembodied spirit of Clark’s biological father, or to provide a side-story arc for one of the main characters, like the creation of Adam Knight.

Main characters

Unlike most shows, which generally get about four weeks of casting, Gough and Millar had five months. In October 2000, the two producers began their search for the three lead roles, and had casting directors in ten different cities. The following is a list of all the characters that are, or at one time were, a main character in the show. During its first season, Smallville had eight regular characters. As of season eight, six characters from the original cast have left the show, with seven new characters coming in over the course of seven seasons.

Clark Kent

Further information: [[:Clark Kent (Smallville)]]

Portrayed by Tom Welling, Clark Kent is an alien being with superhuman abilities, which he uses to help others in danger. Clark is adopted by Jonathan and Martha Kent in the series pilot, when he crash lands to Earth as a three year-old child. Twelve years later, he tries to find his place in life after being told he is an alien by his adoptive father. For most of the series, Clark spends his time running from his Kryptonian heritage, going as far as leaving Smallville, abandoning a quest his biological father Jor-El sends him on in search of three Kryptonian stones of knowledge, continuing his training at the Fortress of Solitude, and unwittingly unleashing a Kryptonian criminal from the Phantom Zone when he refuses to kill Lex.

Lex Luthor

Further information: [[:Lex Luthor (Smallville)]]

Michael Rosenbaum portrays Lex Luthor, the son of billionaire Lionel Luthor, who is sent to Smallville to run the local fertilizer plant. After Clark saves his life the pilot episode, the two become quick friends. Over the course of seven seasons—beginning on the day Clark rescues him from drowning—Lex tries to uncover the secrets that Clark keeps. Lex’s curiosity eventually leads to a blowout between him and Clark in the season three finale. Lex’s investigations ultimately lead to him discovering the truth about Clark’s alien heritage.

Lana Lang

Further information: [[:Lana Lang (Smallville)]]

Portrayed by Kristin Kreuk, Lana Lang is one of Clark Kent’s friends and on-again-off-again girlfriend. In the first season, Lana and Clark’s friendship is just beginning, as she is dating Whitney Fordman during this time. After Whitney leaves for the Marines in the season one finale, Lana and Clark slowly begin to try and start a romantic relationship. In season seven Lana realizes that, even though she loves him, the only way for Clark to help the world to the best of his ability would be if she left Clark, and Smallville for good.

Chloe Sullivan

Further information: [[:Chloe Sullivan]]

Allison Mack portrays one of Clark’s best friends, Chloe Sullivan. Editor of the school newspaper, her journalistic curiosity—always wanting to "expose falsehoods" and "know the truth"—causes tension with her friends, especially when she is digging in Clark's past. She discovers Clark’s secret in the fourth season episode "Pariah", but the knowledge of his secret is eventually stripped away from her by Clark, who wanted to release her from the burden and danger of knowing his secret, in the season eight episode "Abyss".

Pete Ross

Sam Jones III plays Pete Ross, another of Clark's best friends. He hates the Luthors for what he sees as their thievery of his family's creamed corn business, and is the first person Clark voluntarily informs of his secret. It is established in season three’s "Truth", that Pete is in love with Chloe. He kept this truth to himself because of the Clark-Lana-Chloe love triangle already taking place. In season three’s "Velocity", Pete, feeling alienated by Clark, begins hanging around a group of street racers. Pete joins the ranks and becomes successful, but when he refuses to throw a race his life it put in jeopardy. Clark is forced to abuse his powers in order to help Pete win a race, which leads to a falling out between the two friends. The character was written out of the series at the end of season three, citing the trouble keeping Clark's secret was causing him. Pete returns to Smallville in season seven’s "Hero", after gaining superhuman abilities from kryptonite-enhanced chewing gum, which allow him to stretch his body to extreme lengths. Lex learns the truth and blackmails Pete into abusing his powers for Lex’s personal gain. When Pete fails, Lex attempts to have him killed, but Clark saves Pete’s life. Before Pete leaves Smallville again, the two friends settle the issues that were left unresolved between them.

Sam Jones III was the last of the season one series regulars to be cast – being hired just four days before filming for the pilot episode began. Jones, who is African American, was also cast against the Superman mythology where Pete Ross is Caucasian. Jones has stated that he would have understood if the producers had simply created a black character for him to portray, but the fact that they chose to go with him, even though the character has always been white, gave him more honor to be a part of the show. While filming for the first season was in progress, Jones felt like his character should have been given more screen time, but he admits that he eventually realized that the show was about Clark’s journey and that the other characters are there to help his story move along.

"I know that I told you keeping your secret wasn’t hard. But I lied. I walk around every day afraid that I’m going to slip up."

— The stress of knowing Clark’s secret first appeared in season two’s "Ryan". This idea became the ultimate story arc for the character in season three, which lead to him leaving Smallville.

Jones was not alone in his wish to get more screen time, the writers, who were reading internet forums and receiving mail from the audience that requested the same thing, decided that Pete would learn Clark’s secret in season two. The creative team hoped that knowing Clark’s secret would allow the character to be written into more scenes, and become involved on a daily basis with the Kent family. Ultimately, that was not enough to save the character in season three. Pete’s primary story arc in season three became the character’s inability to deal with knowing Clark’s secret, and his growing feeling of abandonment from Clark, who was spending more time with Chloe, Lana and Lex. The feeling of abandonment extended when Chloe replaced him as Clark’s best friend.

Miles Millar has stated that he felt the character was being wasted on Smallville, which lead to the decision of writing the character off the show. Millar hoped that they could bring Jones back with a prominent role in future episodes. There was dissension between the cast and crew over Jones’s character leaving the show. According to Annette O’Toole, Clark needs a guy friend in his life, and she feels that the Kents would have taken Pete in when his parents left Smallville. Though Al Gough does not disagree that writing out the Pete Ross character was the best thing, he does feel that the way the situation was handled could have gone better. According to Gough, Pete’s departure felt rushed, and seemed to lack the importance that it should have had.

Jonathan Kent

File:557px-JohnSchneiderB yPhilKOnstantinPublicDomain.jpg

John Schneider’s background portraying Bo Duke on The Dukes of Hazzard lent to him landing the role of Jonathan Kent. Schneider performed the role for five seasons, before his character was killed off in a scene reminiscent of Glenn Ford's death as Jonathan Kent in Richard Donner's Superman.

John Schneider portrays Jonathan Kent, Martha’s husband and Clark's adopted father. He goes to great lengths to protect his son's secret. After a reporter threatens to expose Clark’s secret to the world in the season one finale, Jonathan chases after him during a storm and almost kills him – he stops only because of what he believes Clark will think of him if he does. In the season three premiere, Jonathan makes a deal with Clark’s biological father, Jor-El, that he will let Jor-El take Clark to fulfill his destiny when the time comes, if Jor-El gives him the power to bring a runaway Clark back home. Season three’s "Hereafter" explains that Jonathan’s heart was strained while he was imbued with all of Clark’s powers – with Jonathan suffering a heart attack at the end of the episode.

In the season three finale, Jonathan objects to Clark’s departure when Jor-El comes for his son. In order to get Clark to leave, Jor-El threatens Jonathan, strangling him with an energy beam. When Clark leaves, Jonathan is left in a coma for three months. In season five, Jonathan decides to run for a seat in the Kansas Senate against Lex. In the season five episode "Reckoning", on the evening that his victory is announced, Jonathan suffers a fatal heart attack.

Millar and Gough wanted a recognizable face for Smallville, and they loved the idea of casting John Schneider as Jonathan Kent because Schneider was already known as Bo Duke from The Dukes of Hazzard. Gough felt that Schneider’s past credit as Bo Duke added belief that he could have grown up running a farm. Schneider was initially uninterested in being a part of the show, but after reading the pilot script he saw the potential for bringing back "real parenting" to television. Schneider particularly saw his character as a means to replace those "goof" father-figures that had become prevalent on television. He also saw his character as a means to keep the show grounded in reality, specifically by making sure that Jonathan’s life is clearly displayed for the audience to see – performing his daily routine on the farm.

According to Schneider, Jonathan is "perfectly willing to go to jail, or worse, to protect his son". The actor characterizes Jonathan as fast to lose his temper, which Schneider views as being a development of his protective nature over his family. Schneider believes that the season two episode "Suspect"—where Jonathan is arrested, but his sole concern is protecting Clark’s secret—summarizes the character well, and shows that the "least important person in Jonathan’s life is Jonathan". Schneider admits that occasionally he and Annette O’Toole have to "police" the creative team when it comes to the relationship between Martha, Jonathan, and Clark. According to Schneider, there are moments where they have to make sure that the characters are not taken to a place they would not normally go, specifically where the parents are useless without the "innate intelligence of [their] teenager".

Tom Welling feels that the deal Jonathan made with Jor-El at the beginning of season three made Jonathan realize that he will not always be around to protect Clark. Welling believes that it is the repercussions of that deal that allow Jonathan to give Clark more freedom in the choices that he makes during season three. Jonathan comes to the realization that it is time to help Clark find the confidence in his ability to survive on his own, so that he will be able to leave home one day. One scene that Schneider specifically remembers was at the end of season three's "Forsaken". Here, Jonathan admits to not trusting his instincts anymore and allowing Clark to rely on his own instincts. This "admission of fallibility", but faith in his son’s ability to make the right choices, is what Schneider sees as the growing of the family dynamic.

For season three, Jonathan also has to deal with his emerging heart problems. For Schneider, the “treatments” and “cures” that his character underwent were all for nothing, as the actor believes that Jonathan’s heart attack at the end of "Hereafter" was less of a real heart attack and more of Jor-El trying to get Jonathan’s attention. A heart condition is not new to the character, as it has been used in previous incarnations, like Glenn Ford’s Jonathan Kent in Richard Donner’s Superman, as well as the comic books. In contrast to those versions, it was Smallville that tied his heart condition to a deal that he made with Jor-El. When the moment came for his character’s death, Schneider considers the event an "empowering death", which he likens to John Wayne’s character death as Wil Andersen in The Cowboys.

Martha Kent

Martha Kent, Clark's adopted mother, is portrayed by Annette O'Toole. Martha, along with her husband Jonathan, gives Clark sage advice about how to cope with his growing abilities. In season two, Martha becomes pregnant with her first child—in the season two episode "Fever", Clark’s spaceship heals her body and allows her to have children, something she physically could not do when she adopted Clark—but in the season two finale she suffers a miscarriage after an automobile accident. In order to help the family financially, Martha takes a job as Lionel Luthor’s assistant in season two, but quits her job the same season in the episode "Suspect". While Jonathan lies in a coma at the start of the fourth season, Martha takes a job running the local coffee shop, the Talon. She continues to manage the Talon into season five until Jonathan dies from a heart attack, which ultimately leads to her taking his state senate seat at the request of the Kansas Governor in season fives "Tomb". This eventually paves the way to a job in Washington, D.C. in the season six episode "Prototype", and the character's exit from the show.

"I have the feeling that she didn't have a mother growing up—they've never introduced a mother for her. That's why being a mother is so important to her—and being the 'picture book' kind of mother at that."

— Annette O'Toole on Martha Kent's parenting.

The role of Martha Kent was originally given to Cynthia Ettinger, but during filming everyone, including Ettinger, realized that she was not right for the role. O'Toole was committed to the television series The Huntress when Ettinger was filming her scenes for the pilot. Around the time the creators were looking to recast the role of Martha Kent The Huntress was canceled, which allowed O'Toole the chance to join the cast of Smallville. Coincidently, the actress had previously portrayed Lana Lang in Superman III. O’Toole thinks that the producers wanted someone older for the role of Martha, and when she came in to talk to the producers everyone appeared to be on the same page with what the character and the show should be about. O’Toole characterizes Martha as really intelligent, but believes the character has to hide her intelligence at times "to keep the peace".

In order to add more depth to her character, and feeling like her character was wasting her college degree, O’Toole suggested to the producers that her character go to work for Lex during the second season. The producers agreed, but altered the concept so that Martha went to work for Lionel, and that she would use this new position to spy on Lionel and find out what he knows about Clark. O’Toole was disappointed when the storyline ended quickly into the second season, and she had hoped that the secret her character was holding in "Ryan" was that Martha was going to run for Mayor. In O’Toole’s opinion, Martha needs some form of outlet for intelligence.

To make matters worse for O’Toole, Martha’s next storyline—the expectation of a new child—tied the character to the farm in a way the actress did not agree with. O’Toole wanted to perform as if the pregnancy was fake—something mentally created by Clark’s ship—but the producers insisted that she wear the pregnancy pads to indicate that she was indeed pregnant. One important outcome for the character, which O’Toole fought for, was that she would not blame Clark for the loss of the baby when she and Jonathan were caught in the shock wave that emanated from spaceship when Clark destroyed it. Before season four began, O’Toole suggested again to the producers that Martha go to work for Lex. O’Toole had enjoyed the moments in the show when she was working for Lionel, because it gave her character something more to do, and she wanted to do that again for season four. The producers took her suggestion and had Martha take a job at the Talon. O’Toole felt this story element allowed Martha to interact with the other characters in Clark’s life.

O’Toole relished the opportunity that came with Jonathan’s passing, even though she was saddened to see a friend leave the show. For her, Martha taking the senate seat was a chance to explore more adult stories with her character beginning midway through season five, which was important for the actress since Clark was becoming an adult on the show. It also allowed for O’Toole the chance to depict "strong emotions" over Jonathan’s death. Al Gough feels that Jonathan’s passing allowed for them to explore more of Martha’s smart and strong side, as well as her relationship with Lionel. The idea was to show that there was some form of attraction between Martha and Lionel, but that Martha would never have any romantic relationship with the billionaire, especially after all that he had done to her family. O’Toole likens Martha’s interest in Lionel with that of watching a dangerous animal: "It’s that attraction you have for a very beautiful, dangerous animal. You know you can’t stop watching it, but at the same time you feel, "Oh my God, he’s going to kill me."" The actress believes that Martha’s ultimate motivation was to protect Clark, to get close enough to Lionel to know what he is planning. When it came time for Martha, and O’Toole, to leave the show writer Todd Slavkin contends that they wanted to give the character "more of a send-off" than they achieved on film. Slavkin explains that they could not do anything equivalent to what they gave John Schneider, as there were already so many storylines going on by the season six finale that they could not fit anything else in. The writers also realized that, because of the mythology, they could not kill off the character. Instead, they chose to send her to the US Senate, creating a parallel to Clark where Martha fights injustice on the political stage.

Whitney Fordman

Eric Johnson appears as Whitney Fordman, Lana's boyfriend, in season one. He becomes jealous of Clark and Lana's budding friendship, going so far as to haze Clark. When his father is stricken with a heart disease, Whitney is forced to run the family business and loses his football scholarship. This results in him ignoring Lana, and hanging around with past high school football stars, who recruit him for their illegal endeavors. He eventually reconciles with Clark and Lana before joining the Marines. Whitney was written out of the show in the first season's finale, but he made appearances in the season two episode "Visage", where it is revealed he died in combat overseas, and the season four episode "Façade", during a flashback of Clark's freshman year.

Eric Johnson auditioned for the roles of Lex and Clark, before finally being cast as Whitney Fordman. When the producers called him in for one more audition, after passing on him for the major roles, Johnson informed them that if they wanted him then they would need to bring him in for a screen-test. After the screen-test, Johnson was cast and spent only one day filming his scenes for the pilot. The producers, along with Johnson, wanted to portray Whitney as more than just the "stereotypical jock" that he could have easily become. Had they done that, everyone believes that it would have just made Lana look stupid for going out with him. Whitney was given multiple storylines in season one in an effort to get audiences to view the character in a more pleasant light, but Kristin Kreuk feels that audiences did not get to know the character well enough, because he was only seen through Clark's eyes.

Johnson realized after reading the script for the pilot episode that his character was not going to be around for the entirety of the series. This became even clearer when his character’s storylines began to develop quickly. While filming "Obscura", Johnson was informed that his character would not be returning as a series regular for season two. Initially fearing that he had made some mistake and that they were going to kill his character off, Johnson learned that Whitney would be enlisting into the Marines. The actor has expressed his pleasure in the way the writers handled Whitney's departure, by giving the character the exit of a hero.

Lionel Luthor

Further information: [[:Lionel Luthor]]

John Glover portrays Lex’s father, Lionel Luthor. Lionel initially sends his son to Smallville to run the local fertilizer plant, as a test. When Lex succeeds in making a profit for the first time in years, Lionel closes the plant down completely and blames it on Lex’s poor managerial skills. As the series progresses, Lionel becomes interested in the Kawatche caves, which have Kryptonian symbols painted on their walls; his interests also extend to the secrets Clark keeps. After being possessed by Jor-El in the season five episode "Hidden", Lionel begins assisting Clark in keeping his secret hidden from Lex. In season seven, Lionel is murdered by Lex, who realizes that his father has been covering up the truth about an alien visitor.

Lois Lane

Further information: [[:Lois Lane (Smallville)]]

Erica Durance first appears in season four as Chloe’s cousin, Lois Lane. Lois comes to Smallville investigating the supposed death of Chloe, staying with the Kents while she is in town. In season five’s "Fanatic", Lois takes a job as Jonathan's Chief of Staff when he runs for state senate; she continues these duties when Martha takes Jonathan’s place following his death. After some reservation, Lois decides that she is interested in journalism and takes a job at a tabloid newspaper called The Inquisitor. This eventually lands her a position at the Daily Planet.

Jason Teague

Jensen Ackles appears in season four as Jason Teague, a love interest for Lana. The pair meet in Paris, while Lana is studying abroad. When she leaves unexpectedly in the season four episode "Gone", Jason follows Lana back to Smallville and takes a position as the school's assistant football coach. In season four’s "Transference", Jason is fired from the school when his relationship with Lana comes to light. By the end of the fourth season, it is revealed that he has been working with his mother Genevieve (Jane Seymour) to locate the three stones of knowledge — three Kryptonian stones that when united form a single crystal that creates Clark’s Fortress of Solitude. The Teagues kidnap Lex and Lionel in an effort to discover the location of one of the stones in the episode "Forever". In the season four finale, Lionel claims that Lana has one of the stones. Genevieve confronts Lana, and the two women get into a struggle with Genevieve dying by Lana’s hand. Jason, who believes that the secret of the stones lies with Clark, heads to the Kent farm where he holds Jonathan and Martha hostage until they tell him where Clark is hiding the stones. He is killed during the second meteor shower, when a meteor falls through the Kent home and lands on him.

The creation of the character was something handed down by the network, who wanted Lana to have a new boyfriend – one who was "different from Clark". There was apprehensive because they were already introducing Lois Lane into the series, and introducing two new characters would be difficult. Gough and Millar began rethinking where the relationship between Clark and Lana had left off at the end of season three, and they realized that Clark had turned his back on Lana. The pair began to like the idea of bringing in a new character, one that would create a new love triangle; eventually they tied him into the larger storyline involving the three Kryptonian stones of knowledge.

According to writer Brian Peterson, where Clark brings "angst" and "depth" to his relationship with Lana, Jason is designed to bring "joy", "levity", and "fun". On the topic of Jason’s relationship with Lana, Ackles believes the character did love Lana, because he saw an innocence in her that had not been able to experience growing up in the upper class society; Jason grew up having to question the actions of his mother, and with Lana he had the opportunity to experience an honest relationship. Jensen Ackles was Gough and Millar’s first choice to place Jason Teague, as the actor had been the runner up for the role of Clark Kent when they were casting for the pilot. Ackles received top billing for season four. He was contracted to remain through season five, but was written out of the show in the season four finale, which, according to Ackles, was due to his commitments to the WB’s new series Supernatural. Gough contends that Supernatural did not alter any of their plans, and that Jason Teague was intended to be a single season character.

Jimmy Olsen

Aaron Ashmore, whose identical twin has also appeared on the show, joined the cast as a recurring guest in season six. When he returned in season seven his character had been moved up to series regular status.

Jimmy Olsen is first mentioned in season four as the person Chloe lost her virginity to while interning at the Daily Planet. He first appears, portrayed by Aaron Ashmore, in the season six opener. Working as a photographer for the Daily Planet, Jimmy rekindles his relationship with Chloe in the season six episode "Wither". In the episode "Hydro", Jimmy works with Lois to uncover the true identity of Green Arrow, and in season seven, when Lois is hired by the Daily Planet, the pair work together on finding stories for the paper. When Jimmy’s relationship with Chloe comes to an end—due to her keeping the truth about her developing powers a secret, as well as to the nature of her relationship with Clark—Jimmy begins a brief romantic relationship with Clark’s cousin Kara in season seven’s "Cure". After he and Chloe rekindle their relationship in the season seven episode "Sleeper", Jimmy falls into Lex’s debt when Lex, at Jimmy’s request, keeps Chloe from being arrested by the Department of Domestic Security for hacking into their government files. In the season seven finale, Lex goes back on his word and has Chloe arrested, just as Jimmy proposes marriage.

After being saved by Oliver Queen and Clark in the season eight premiere, Chloe is reunited with Jimmy and accepts his marriage proposal. In "Committed", a deranged jeweler kidnaps Jimmy and Chloe after their engagement party and subjects them to a torturous test to see if they truly love each other — they both pass and are allowed to return to their normal lives. In the season eight episode "Identity", Jimmy begins to suspect that Clark is the "Good Samaritan", an individual who has been stopping crimes and saving people’s lives around Metropolis, until Oliver Queen dresses up as the "Good Samaritan" to help Clark trick Jimmy into believing he was mistaken. In the eighth season episode "Bride", Jimmy and Chloe are officially married, but Doomsday crashes their wedding and kidnaps Chloe, leaving Jimmy in the hospital because of injuries sustained from Doomsday.

Ashmore indicates that his casting was both a surprise and what he wanted. The actor states, "I auditioned for [the role] and I put myself on tape. I hadn't heard anything, and a couple of weeks later, all of the sudden, I got the call saying, 'You're going to Vancouver to start shooting Smallville.' It's a dream come true, really." Aaron Ashmore’s identical twin, Shawn, who is better known as Bobby "Iceman" Drake in the X-Men film series, appeared in two episodes of Smallville as the power leeching Eric Summers.

Kara

Laura Vandervoort joined the cast in season seven as Kara, Clark's Kryptonian cousin. She arrived on Earth at the same time as Clark, with the mission to protect her cousin, but was stuck in suspended animation for eighteen years. In the season seven premiere, Kara is released from suspended animation and saves Lex from drowning. A brief glimpse of Kara flying into the sky results in Lex’s new obsession with finding the "angel" that saved his life. Kara eventually finds Clark, in the episode "Kara", who informs her that Krypton was destroyed when the two of them were sent to Earth, and everyone there is dead. Clark teaches Kara to control some of her abilities, and at the same time blend into society. In season seven’s "Lara", Kara is captured by the Department of Domestic Security and tortured, where she relives one of her early memories of visiting Earth with Clark’s mother, Lara. She realizes that her perceptions of her father were wrong and that he was as evil as Clark said. Kara and Clark have to work together to fight her father, Zor-El, who was unwittingly released when Clark attempted to create a clone of his biological mother in the episode "Blue". When Zor-El is destroyed at the end of the battle, Kara disappears from the Fortress of Solitude. She awakens in Detroit with amnesia and none of her abilities.

Laura Vandervoort joined the cast of Smallville in season seven as Clark's biological cousin Kara, but was written out of the series in the season seven finale.

In the episode "Fracture", Kara is discovered and brought home by Lex, who wants to exploit her amnesia to his benefit, with the intent of discovering the truth about Clark. In the season seven episode "Traveler", Lex makes plans to help Kara regain her memory. Chloe convinces Jor-El to return Kara’s memory and powers before Lex can learn her and Clark’s secret – Jor-El agrees. When Lana is placed in a catatonic state by Brainiac in the episode "Veritas", Kara agrees to cooperate with him in the hope that he will not kill Lana. In "Apocalypse", Kara is taken through time to Krypton, just before it explodes, so that Brainiac can kill the infant Clark. With Jor-El’s help, Clark manages to arrive on Krypton and stop Brainiac. Unknown to Clark, Brainiac is not killed in their fight on Krypton, and he manages to place Kara in the Phantom Zone, while he assumes her identity back on Earth. In the season eight episode "Bloodline", Clark is transported to the Phantom Zone, where he finds Kara. Working together they escape, and Kara leaves Earth to search for Kandor, a city rumored to hold surviving citizens of Krpyton.

Vandervoort does not return as a series regular for the eighth season, but returns as a guest star in the season eight episode "Bloodline".

Oliver Queen

Justin Hartley portrays Oliver Queen, a billionaire who left Star City to live in Metropolis. In the season six episode "Sneeze", Oliver kidnaps Lex after watching footage of Lex—possessed by the Kryptonian criminal General Zod—break into the Pentagon and repel bullets fired at him. After learning that Lex no longer has his powers, Oliver is informed by his assistant that another individual, Clark, has been exhibiting the same abilities. In the episode "Arrow", Oliver begins masquerading around Metropolis as a costumed vigilante, named Green Arrow by Lois, who steals from the rich—only stealing objects he knows were already stolen by those wealthy individuals—and gives to the poor. Oliver uses high-tech gadgets, such as experimental arrow tips for his compound bow and sound synthesizers to hide his true voice, to fight crime. Oliver also begins a romantic relationship with Lois.

In the season six episode "Rage", Lois and Oliver’s relationship begins to strained because of Oliver’s constant disappearing acts. In the episode "Justice", Oliver and Clark—along with Bart Allen, Arthur Curry and Victor Stone—band together to take out one of Lex’s secret 33.1 facilities, where Lex experiments on meteor-infected individuals against their will. After destroying the facility, Oliver invites Clark to join his team, but Clark declines. Oliver and Lois break up when Oliver is forced to leave town to track down more of Lex’s 33.1 facilities. Lex, fed up with Green Arrow and his team, sends vigilante Dinah Lance to kill Green Arrow in the season six episode "Siren". The vigilante, who is dubbed the "Black Canary" by Chloe and Clark, learns that Green Arrow is not the terrorist she was led to believe, and joins his team instead of fulfilling her contract with Lex.

Oliver tracks down and rescues Clark in the season eight opener, after the latter goes missing when his Fortress of Solitude is destroyed. Afterward, Oliver and his team disband for fear that their identities have been compromised. In the season eight episode "Toxic", it is revealed that Oliver has a romantic past with Tess Mercer, Lex Luthor’s hand-picked successor who took over LuthorCorp after Lex went missing following the collapse of the Fortress of Solitude. Oliver believes he has tracked down Lex’s whereabouts in the episode "Bride", but he does not find Lex when he arrives; Oliver reveals that he plans to kill Lex when he does find him.

According to Al Gough, Justin Hartley was the producers’ first choice to play the role of Oliver Queen, and his alter-ego Green Arrow. The introduction of the character was designed to provide an alternative view for what it means to be a hero. At the same time, the producers wanted a character that could impact the lives of both Clark and Lois. Writer Tracy Bellomo characterizes Oliver as a guy that does not take himself very seriously, and enjoys making fun of people that try to take him that way. Bellomo believes that this is one of the reasons that he is attracted to Lois, with the other being that Lois provides a challenge for him. Oliver’s relationship with Clark is designed to "broaden Clark’s rather limited horizons", and to teach Clark that a world exists beyond Smallville. Hartley was a recurring guest in the sixth and seventh seasons, but becomes a series regular in season eight.

Tess Mercer

Cassidy Freeman portrays Tess Mercer, who is the acting CEO of LuthorCorp that was picked by Lex to run the company should something ever happen to him. Tess Mercer's primary goal in season eight is finding Lex, which draws her inquisitively to Clark, whom she believes will be able to help her find Lex. Tess’s first contact with Clark is when he pulls her from a wrecked city bus in the season eight episode "Plastique"; she immediately suspects that Clark is not telling her all that he knows about Lex’s disappearance. That same episode reveals that Tess is bringing together a group of meteor-infected individuals, and in "Plastique" she recruits Bette, a young girl with the power to create combustion on command. In the episode "Prey", Tess enlists a young man who can turn himself into a shadow. In "Toxic", it is revealed that Tess had a brief romantic relationship with Oliver Queen after she saved his life while he was stranded on an island. In the season eight episode "Instinct" and "Bloodline", Tess learns about Krypton and the name "Kal-El", though she does not attribute any of the information directly to Clark.

The name "Tess Mercer" is a homage to two characters from Superman lore, Eve Teschmacher and Mercy Graves. As Freeman describes her character, Tess Mercer is Lex's handpicked successor; she is "fierce", "fun" and intelligent.

Davis Bloome

Sam Witwer portrays Davis Bloome, a paramedic for Metropolis General Hospital. He first appears in the season eight episode "Plastique", assisting Chloe with helping an injured person after a bomb explosion. In the episode "Toxic", Chloe calls on his help when Oliver is poisoned and refuses to be taken to a hospital. In "Prey", Clark begins to suspect that Davis is a serial killer after he finds Davis unconscious at one of the murder scenes, and learns later that Davis is usually the first paramedic to arrive on similar scenes. Davis starts to suspect the same thing himself when he begins to lose track of large portions of time, and finds himself covered in blood. Davis confides his fears to Chloe, who reassures him that he could not be capable of such violence. Davis learns in the episode "Bloodline" that he was genetically created by Faora and General Zod, after the pair could not physically have children, to be Earth’s ultimate destroyer. Faora, upon informing Davis of who he really is, stabs and kills him – Faora whispers in Davis’s ear that whatever kills him will make him stronger. Afterward, Davis wakes in a pool of his own blood, but the stab wound has healed – Davis attempts to stab himself but the knife he uses shatters when it hits his chest. In the season eight episode "Abyss", Davis confesses to Chloe that he is in love with her, and believes that she is marrying the wrong man. On Chloe’s wedding day, in eighth season episode "Bride", Davis, caught by a security guard disposing of bloody garbage bags, transforms into a hulking monster, called Doomsday, with boney protrusions coming out of every part of his body and face. Doomsday travels to Smallville, interrupts Chloe’s wedding, injures Jimmy, and kidnaps Chloe.

Davis is actually Smallville's interpretation of the comic book character Doomsday, the only character to have succeeded at killing Superman. In Smallville, Doomsday is represented as a "nice guy" paramedic, who grew up moving from foster home to foster home. His storyline is considered "very dark" in that the character uncovers horrible truths about himself as season eight progresses. Brian Peterson explained that he, and the rest of the new executive producers, were looking for a villainous character that was "as great as Lex", with Michael Rosenbaum's departure at the end of the seventh season, and Doomsday fit what they were looking for.

Recurring characters

The following is a list of the characters that are, or at one time were, a recurring guest on the series, in the order that they first appeared on the show. Thirteen characters have had minor story arcs that have spanned multiple seasons, while the others were restricted to arcs that occurred during a single season of the show. Two of the recurring guests have strong connections to the Superman mythology. The first is Christopher Reeve, who played Superman in the four major motion pictures featuring the titular comic book character. The second is Terence Stamp, who portrayed Superman’s nemesis, General Zod, in Superman II, and who had a brief appearance as the same character in the first film.

Sheriff Ethan

Sheriff Ethan is portrayed by Mitchell Kosterman in seventeen episodes spanning seasons one and two. Kosterman’s first scene as Ethan came in "Jitters", which was originally scheduled to be the third episode of season one but was pushed back to the eighth position. Ethan’s first few appearances only involved a few lines of dialogue. Season one’s "Rogue" introduced the idea that Sheriff Ethan had a history with Jonathan, and it was that moment that Kosterman felt like he was more than a background image for the show. That history was used against Jonathan, when Ethan framed him for the attempted murder of Lionel Luthor. Ethan's subterfuge was discovered by Clark and Pete, who set up a scheme of their own to bring Ethan's action to light. Once revealed, Ethan immediately surrenders to the authorities. Kosterman, who has played law enforcement officials on other television programs, initially turned down the role. After his agent informed him it would be a recurring role, and that the producers were willing to pay him more than he made on any previous show, Kosterman decided to take the job. The show’s producers were all in favor of making Mitchell’s character the villain in season two’s "Suspect". To executive producers Mark Verheiden and Greg Beeman, this was the ultimate red herring for audiences. Initially, Sheriff Ethan was going to take a nurse hostage at the end of the episode, but it was rewritten to leave Ethan as more of a sympathetic character. Mitchell prefers the filmed ending, as he could not see any reason why his character would suddenly become evil. Mitchell believes that his character fell into the established theme that "good people being pushed to do the wrong thing by bad people like Lionel Luthor".

Dr. Helen Bryce

Dr. Helen Bryce, portrayed by Emmanuelle Vaugier in nine episodes between seasons two and three, is a Smallville medical doctor who first appears in an anger management class that Lex is sentenced to attend. She and Lex begin a romantic relationship, which becomes a concern of Jonathan’s when Helen—after taking a sample of blood from Clark during a period when he was infected by kryptonite—discovers that Clark is not human. Helen promises Jonathan that she will keep Clark’s secret, but at the same time she does not destroy the vial of blood she took for him. As a result, the blood is stolen from her office, though it did not have Clark’s name on it. Her relationship with Lex becomes serious when he proposes marriage to her.

The day before her wedding, Helen leaves Lex, after discovering that he was the one that stole the vial of blood. She returns, forgiving him, and goes through with the wedding. While on the LuthorCorp jet, destined for their honeymoon, Lex passes out and wakes to an empty plane that crash lands in the ocean. After three months, the search for Lex is called off and he is declared dead. Helen appears at Lex’s funeral, grieving the loss of her husband, to Lionel’s disgust. When Lex returns he discovers that Helen was responsible for the plane’s crash. Lex orchestrates his own plan for revenge, which results in Helen disappearing while the two go on their second honeymoon.

By the time of season two's nineteenth episode, the writers had decided Helen's fate. Originally, the character was going to die on her wedding night, but the creative team felt that they could use her more in the mythology. Gough explains that the idea that Helen still had Clark's blood, she knew his secret, and her relationship with Lex was too good to write off. The creative team kept Helen's true motivations a secret to Vaugier, which the actress enjoyed because it allowed her to play the character as if there were no ulterior motives.

Dr. Virgil Swann

Christopher Reeve appeared in two episodes of Smallville. When filming his scenes, Reeve would often give the director suggestions about ways to shoot around his chair, so that it would not be so obvious that he was paralyzed.

Christopher Reeve appeared twice as Virgil Swann, a scientist who was able to translate the Kryptonian language. In 1989, the day of the meteor shower that brought Clark to Earth, Virgil Swann's team of scientists receives a message from space. Swann deciphers the message, which states that a child was sent to Earth and that whoever should find him should protect him from evil. When Swann sees a burned Kryptonian symbol on the Kent barn he immediately contacts Clark, in hopes that he was the child the message spoke of. Clark visits Swann at his conservatory, where Swann gives him two messages that were intended for him, one of which informs Clark that his birth name is "Kal-El". When Lionel begins piecing together the alien language on the Kawatche cave walls, and Clark's constant presence at the caves, he seeks out Swann for the answers. Swann, though he denies knowing how to read the symbols in the caves, agrees to help Lionel when it correctly guesses that Lionel is dying; how Swann helps Lionel is not made clear. Some time later, Swann dies. Clark receives a package from Swann, just before learning of his death, which contains the octagonal disk that had been missing for some time.

"Dr. Swann provided the first tantalizing answers to the quest that had been plaguing Clark for all of his young life. 'Where am I from?' 'What happened to my parents?' 'Am I truly alone?"

— Gough and Millar on Dr. Swann's significance

Gough and Millar always had intentions of bringing Christopher Reeve onto the show. When the pair learned that Reeve enjoyed watching Smallville, Gough and Millar decided that they were going to bring him on for season two. They had already crafted a character, Dr. Virgil Swann, they knew would reveal the truth about Krypton to Clark, and they decided that Reeve would be perfect for the part. According to Gough and Millar, it was "natural" for Reeve to be the one to educate Clark about his past, and help him see his future. As Gough describes it, the scene between Clark and Dr. Swan is a "passing of the torch" moment for the series. The creative team decided to fly to New York to film Reeve's scenes since he is confined to a wheelchair and requires much assistance when he travels. Although James Marshall directed the episode, for Reeve's scenes in New York the Smallville crew sent Greg Beeman as a stand-in director. Gough, Welling and Mat Beck travelling alongside Beeman to New York, and John Wells, who had previously lent his White House office on The West Wing to the Smallville crew for season one's "Hourglass", allowed the team to use the production offices from the Third Watch for Reeve's scenes.

"I thought it would be fun; it’s a very welcome relief from politics and medical research. Butting heads with politicians and the whole establishment in terms of advancing medical research is a very difficult job, and time-consuming and energy-consuming, and this is a very welcome change of pace."

— Reeve's experience filming

There was initial concern about Reeve's stamina for shooting the scenes, as his particular scene with Welling was six pages long, which translates to approximately twelve hours of work day. Beeman tried to design the scene so that it was as simple as possible, but Reeve quickly readjusted the scene. Beeman originally had Welling walk into frame and stand in front of Reeve, and then make a single move behind Reeve. Beeman was told, by Reeve, that the scene needed more dynamic between the characters, and if Welling only made a single move then the dynamic would be lost. According to Reeve, "Tom moving around me will hide the fact that I'm unable to move." Beeman's fear of overstretching Reeve’s stamina, because of the added shots to the scene, were put to rest when Reeve himself stated that it did not matter how long it took to finish the scene, as long as it turned out great. Reeve was directing Yankee Irving when Smallville was gearing up to film the fourth season opener. As a result, Reeve could not reprise his role as Dr. Swann, which was the intention.

Sheriff Nancy Adams

Camille Mitchell appeared as Sheriff Nancy Adams in 22 episodes of Smallville, spanning the course of four seasons. Sheriff Adams makes her first appearance in Smallville when she arrests Clark for getting into a fight with another patron of the Talon. During an investigation into a triggered alarm at the Luthor Mansion, Adams is killed by two rogue police officers looking for the black ship that landed during the second meteor shower. Mitchell makes a special appearance as Nancy Adams in season seven. In this episode, Clark is taken to an alternate reality, where he meets Adams, who is a Department of Domestic Security agent providing Lois, who is a Pulitzer Prize winning reporter, with inside information on President Lex Luthor’s operations.

Camille Mitchell had auditioned for the role of Byron’s mother in "Nocturne"; Greg Beeman had remembered the audition and had the actress come in to read for the role of Sheriff Adams. Mitchell did some research for the role, talking with female law enforcement officers to gain an understanding of how they evaluate situations. Mitchell views her character as a "down-to-earth sheriff" that carries with her a "farmer’s common sense". The actress believes that a character like Nancy Adams lends to the realism the show tries to portray within its comic book environment. Gough describes Sheriff Adams as "a cross between Holly Hunter and the sheriff in Fargo".

Adam Knight

Adam Knight appeared in six episodes of season three; he was portrayed by Ian Somerhalder. He is first seen as a fellow patient of Lana’s at the Smallville Medical Center; he helps Lana push through her physical therapy after she was trampled by a horse. The two develop a friendship, which blossoms when Lana offers to rent Adam the apartment above the Talon coffee shop. Adam’s actions—specifically his injection of an unidentified drug developed by LuthorCorp, which is revealed to be the only way he can keep his body alive, after having died of a rare liver disease—begin to arouse suspicion in Lana and her friends. Lana discovers that Adam has been keeping a journal of all her actions, as well as all of Clark’s, so she tries, and fails, to evict him.

Lana enlists Lex’s help to get rid of Adam, but Adam disappears before Lex can do anything. Lex tracks Adam’s whereabouts to a LuthorCorp lab run by Dr. Tang, where Dr. Tang is injecting Adam with an experimental drug—this was against Lionel’s order, who cut-off Adam’s supply when he failed to deliver any new information on Clark—to keep him alive. Adam eventually breaks out of his confinement, killing Dr. Tang and the rest of the lab technicians. He kidnaps Lana and attempts to kill her, but Clark stops him. Without his serum, Adam’s body begins to rapidly degenerate until he finally dies.

Internet speculation had the character of Adam Knight actually being that of Bruce Wayne, but the crew contest that theory, arguing that it was never their intention to reveal Adam Knight to be a young version of Bruce Wayne. The actual intention was for Adam to be Lana’s new boyfriend—a legitimate relationship—but the chemistry between Ian Somerhalder and Kristin Kreuk was not working. The creative team decided to bring the character’s storyline out of the romantic path and into a “thriller Pacific Heights direction”. According to Gough, the character’s storyline degenerated into a science fiction story, and when that occurred, they decided they had to wrap it up quickly.

Milton Fine

James Marsters appears in eight episodes of season five, as well as four episodes of season seven, as Milton Fine. Brought to Earth by the two disciples of Zod, Fine poses as a professor at Central Kansas A&M, where he befriends Clark. Fine's ultimate plan is revealed when he attempts to use Clark’s Fortress to release Zod from the Phantom Zone. Clark prevents Zod from being released, and presumingly destroys Fine. A few months later, Fine reappears and teams up with Lex to develop a super-vaccine, one that would be able to cure all of the world's most deadly diseases. Fine is revealed to actually be an artificial intelligence, known as the Brain-Interactive-Construct. Fine explains to Clark that he was supposed to become the vessel for Zod’s spirit, but Lex became Clark’s replacement. In the season five finale, Fine unleashes a computer virus that cripples the world’s cyber infrastructure. Clark is then tricked into using a Kryptonian dagger, given to him by Jor-El to destroy Zod’s vessel (Lex), to kill Fine, who uses the dagger to provide himself with a link to the Fortress of Solitude and release Zod’s spirit into Lex.

James Marsters was the creators' first, and only choice to play Brainiac; had Marsters decline the role then Al Gough and Miles Millar would have replaced Brainiac with another character from the DC Comics universe.

In season seven, it is revealed that a small fragment of the black ship had been recovered by Lex, whose scientists were using meteor rocks to keep it subdued. The containment unit holding the fragment is broken and the fragment injects itself into a lab technician. Draining the lab tech of her natural metal content, along with several other victims in Metropolis, the fragment soon re-forms into Milton Fine. Fine learns that his creator, Dax-Ur, is on Earth and he pits Clark and Clark's clone against each other so that they will lead him to Dax-Ur. Once found, Fine kills Dax-Ur by downloading Dax-Ur’s knowledge from his brain, knowledge that allows Fine to repair himself. Fine’s new plan is to go back in time and kill Clark before his biological parents can send him to Earth. When that plan fails, Fine assumes Kara’s identity, leaving her in the Phantom Zone, and returns to Earth to find the device Veritas was hiding that could control Clark. Clark discovers the truth and destroys Fine.

Gough and Millar always had their eyes set on casting Marsters as Milton Fine/Brainiac. The pair wrote a draft for the major story arc for season five, knowing that they wanted a new villain on the show to fight Clark. With the arrival of the black ship at the end of season four, Gough and Millar decided to introduce Brainiac. To them, Marsters was the only actor they could envision that could fit the "menace, intelligence, and sexiness” that Brainiac was going to embody. Had Marsters declined the role, Gough and Millar would have rethought introducing Brainiac, as they could not think of any other actor that could fill those shoes. Marsters felt excited playing a character that was completely intentional; he likened the intention to that of a shark. As Marsters explains, "[Fine] was just composed of his intent. And that’s exciting—it’s like watching a shark. You don’t really ask how a shark is feeling—it’s pure." Fine was trying to seduce Clark to his side, and his philosophy that humans are beneath him (Clark).

Writer Steven DeKnight, who wrote for Marsters when he was portraying Spike on Buffy the Vampire Slayer, used a different approach for Marsters when writing for him as Milton Fine. Spike is more "snarky", and DeKnight felt that Fine is more sincere, and a "straight-ahead classic villain". This different approach to villainy worked well for Marsters, who wanted to show people that he could portray characters, who were not Spike, effectively. Marsters describes Brainiac as "a murderous robot" with no remorse over his actions. According to Marsters, the character is an "intellectual" who is focused on what he wants. Marsters was drawn to the series because of the "refreshing" take the producers had with the concept for the show. Marsters appreciated the idea of a show about Clark's journey toward becoming Superman.

The actor states that it is "great playing a robot that is pretending to care". Marsters did have an initial apprehension about taking the role, as the actor was familiar with who he was portraying and he did not wish to be turned green and wear the character's traditional pink outfit. Little research was needed for Marsters while preparing for the role, as Brainiac's backstory only consisted of a few comic book panels. Marsters believes that his character wants to get rid of the humans because they are doing nothing but destroying their own planet, and Brainiac sees it as his duty to perform "pest control" on the species. Marsters was going to appear in season six, but, when his schedule filled, his character was "killed" so that the producers could "close the door" on his character's storyline. Marsters was approached by Gough and Millar about returning to the show; this time Marsters had free time in his schedule and he returned as Brainiac for the seventh season.

John Jones

Phil Morris was selected to portray Martian Manhunter for season six. Morris has appeared in four episodes as the character, with an unknown actor portraying his first cameo on the show. In his first appearance, the character is not identified by name, nor shown for more than just a brief glimpse. He saves Clark during a fight with an escaped Phantom Zone criminal, and then flies off into the night. The only identifying features are the dropped oreos, a favorite of his comic book counterpart, and a red trail that is left in his wake as he flies away. Although he never introduces himself in the show, in the episode "Crimson", Chloe uses the name "Martian Manhunter" when she describes him, and the official description for "Bizarro" lists his name as John Jones — spelled J'onn J'onzz in the comics. At the start of season eight, John sacrifices his powers when he takes Clark to the yellow Sun to restore Clark's powers, after they are lost when Lex uses the Kryptonian orb to bring down the Fortress of Solitude. Later, John takes a job as a police detective so that he can stay close to Clark, in case Clark needs his assistance, when Clark starts using a police scanner to locate crimes in progress and stop them.

Morris stepped in for the character's first official appearance, guiding Clark out of a fictitious reality that was created by a Phantom Zone criminal attempting to take over Clark’s body. It is revealed in the season six finale that he has been working with Lionel, and was once an emissary of Jor-El’s. He has been watching over Clark since his arrival on Earth, instructed, by Jor-El, only to interfere if Clark’s life was in true danger – Clark’s recent battle with the escaped Phantom Zone criminals qualified for interference. When the last of the Phantom Zone criminals clones Clark's DNA, turning himself in Clark’s doppelganger, Martian Manhunter lends his assistance in defeating the clone. Upon learning of Clark's cousin Kara's existence on Earth, he echoes Jor-El's warning of Kara. In the season eight premiere, John arrives just as Clark is about to die—having lost his powers when the Fortress collapsed—and takes Clark to the yellow Sun to restore his powers. In the process of restoring Clark's powers, the yellow Sun also takes John's powers from him, leaving him mortal on Earth.

Morris was approached by the producers for the part of Martian Manhunter. The actor came into audition twice, and then waited three weeks before he received the call to confirm that he has received the role. Morris relished the new design of the character, stepping away from the cape and tights, and going with a more contemporary look. Morris classifies John Jones as Jor-El’s "tool, security force, his guardian, and his protector". The actor has stated that he would like his character to lead the future Justice League on the show, as he sees John Jones as a natural leader.

Grant Gabriel

Michael Cassidy appears in seven episodes of season seven as the Daily Planet's newest editor, Grant Gabriel, and the love interest for Lois this season. Shortly after hiring Lois, in part to inspire better stories out of Chloe, Grant begins a romantic relationship with Lois. The couple's secret is discovered by Chloe and Lex, who both insist Lois and Grant break up to prevent questions about how Lois actually got her job. The two stay together, working harder to keep their relationship a secret. After Lex buys the Daily Planet, it is revealed that Grant is actually a clone of Lex's baby brother, Julian, who died as an infant. When Grant discovers this information he attempts to connect with Lionel and keep Lex from controlling his life, which has been nothing but a lie manufactured by Lex to begin with. When Lex cannot control Grant he has him murdered.
