Clark's (Kent and Luthor) secret is made up of a combination of five (at times varying) truths:
- He was born as the Kryptonian Kal-El, an alien from the planet Krypton.
- As a Kryptonian under a yellow sun, he has extraordinary powers.
- He has weaknesses: kryptonite (especially green kryptonite) and magic.
- Clark Kent uses his powers to save people and fight crime: first anonymously in Smallville, then later under the guises of the Good Samaritan, Red-Blue Blur, The Blur, as well as finally Superman in Metropolis (Earth-1). Clark Luthor uses his powers for personal gain and domination, willing to commit murder to do so: using the guise of Ultraman he rules Metropolis as a tyrant with an iron fist (Earth-2).
- Clark believes that he is responsible for the 1989 meteor shower, when his spaceship arrived in Smallville. The meteors caused many deaths (including Lana Lang's parents): it also caused many mutations, resulting in a number of psychotic villains. In this way, Clark always believed himself to be indirectly responsible for many of the bad things that have happened in Smallville. However, it was revealed in Season Seven's Apocalypse, when he traveled to a reality where his ship never made it to Earth, that the meteor shower would have happened anyway and, without him in the picture, the planet would have been worse off. This lifted a huge weight off of Clark's shoulders and he soon began to step out of the shadows and fight crime as the vigilante known as The Blur, as well as subsequently Superman.
In addition to his own secret, Clark tries to conceal related information as much as possible (his spaceship, other Kryptonians, Brainiac, the Phantom Zone, phantoms, the meaning of the cave writing, his fortress, the crystals, others with special abilities (including his dog), time travel, parallel universes, etc.). He also tries to conceal his feelings for Lana and Lois whenever he feels that their safety and/or happiness are at stake. (For example, as long as he thinks that Lana loves Whitney, he doesn't interfere.)
Learning Clark's Secret
It often takes time for someone in Clark's life to learn his full secret, if they ever do.
Clark discovering his powers
- Clark displayed super strength as a kid, although his parents taught him that he shouldn't tell anyone else about them.
- He discovered his super speed at the age of 6. (Transference)
- At the age of 14, Clark discovered his invulnerability when he was hit by Lex Luthor's car. (Pilot)
- When Clark asked his father about his strange powers, Jonathan told him that Clark had landed in a spaceship on the day of the meteor shower. (Pilot)
- Clark encountered kryptonite and felt sick while playing near Creekside Foundry with Pete Ross and Greg Arkin as a kid. (Metamorphosis).
He was also weakened by Lana's necklace, (Pilot)
but he didn't know why until Coach Walt Arnold trapped him in a sauna with meteor rocks and he figured out that those made him weak. (Hothead)
- Clark discovered his X-ray vision after a football training in the boy's locker room. (Hothead)
- Clark discovered his heat vision while watching a sex-education video in the biology class. (Heat)
- Clark used his super leap ability for the first time to jump from the Daily Planet skyscraper to the LuthorCorp Plaza skyscraper where Martha and Lionel were held hostages. (Insurgence)
- Clark learned from Dr. Swann that he had come from the planet Krypton. (Rosetta)
- Clark discovered his super hearing when he was blinded by a reflection of his heat vision at green kryptonite. (Whisper)
- When re-programmed as Kal-El, Clark showed the ability of flight (Crusade).
Back to his normal self, he was not able to use this ability again until Finale, Part 2 (the jump onto a nuclear missile in Hidden was rather a super-leap than a flight).
- When Clark had caught a cold, his sneeze blew the barn door off its hinges. This led Chloe to suggest he might have a super breath which proved to be true when he blew down a steel door. (Sneeze)
- The voice of Jor-El told Clark further details of his origin and his destiny. (many episodes)
Clark disclosing his powers to other people
- Clark showed his powers to Pete Ross after Pete had found the spaceship, as well as he told him about his alien origins (Duplicity). At that point in Season Two, Clark himself didn't know where he came from, telling Pete that "I don't know where that ship brought me from." Pete discovered Clark's weakness later in that same episode, when Clark told him that he's "allergic to the meteor rocks." Pete's difficulties in keeping Clark's secret, leading to his decision to leave Smallville (Forsaken) prevented Clark from disclosing his secret to further people, even from telling it to Lana.
- Under the influence of red kryptonite, Clark showed off his invulnerability in front of Ted Palmer and Lionel Luthor by firing a gun into his palm and then dropping the bullets. Even if Lionel was blind at this time and Ted Palmer was later killed, it is shown that Lionel has collected the deformed bullets. (Red)
- Clark uses his Heat vision in the presence of Cyrus Krupp, who believed himself to be an alien, in order to save him from attackers. (Visitor)
- Clark used his powers in front of Alicia Baker to prevent an elevator accident. (Obsession) She overheard him talking with his parents about his vulnerability to kryptonite, as well as later used both green and red kryptonite against him. It is unlikely that she ever learned about his alien origins, as she repeatedly told Clark how similar they were, since they both had secret powers that other people didn't understand.
- Clark told Chloe the rest of his secret, especially his alien origins, when she told him that she knew already about his super strength and speed. (Arrival)
- Clark showed Lana Lang his powers and proposed to her in the Fortress of Solitude. But then, Lana was killed in a car accident and Clark used a crystal to go back in time to change it. In doing so, Clark decided not to tell Lana his secret so that Lana neither learned the secret nor was proposed to. (Reckoning)
After Lana had secretly witnessed Clark's powers at the day of her marriage (Promise), Clark told her he was an alien shortly before she faked her death. (Phantom)
- Clark used his heat vision to help Oliver Queen in his Green Arrow suit to escape from Lois who was about to unmask him to learn his identity. He then stopped Oliver who rode away on his motorcycle and said he owned him one from which Oliver learned about Clark's super powers. (Arrow)
- Clark showed Javier Ramirez his super speed to save him from the police. (Subterranean)
- Clark showed Richtor Maddox his invulnerability to be admitted to his underground fight club. Maddox was shortly after killed by Titan. (Combat)
- Clark disclosed Lois Lane his secret twice in an alternate timeline:
He used his powers in to prevent Lois from being arrested when he was taken by Jor-El to an alternate universe in which he never had arrived at earth. Lois's immediate reaction was to assume that he was a meteor freak and she said "Pretty handy having a meteor freak on my side." Clark corrected her misunderstanding, saying, "I'm not a meteor freak." (Apocalypse)
Clark told Lois his powers and his alien origin so she could write an article about him instead of Linda Lake. When Clark reversed time, this never occurred. (Infamous)
Clark finally told Lois that he was the Blur in the main timeline after she had already reckognized him by a kiss. Clark said the only way they can share a life together is if she knows his secret and that there's no one else he'd rather take that chance with. Lois, overjoyed, pounces on Clark in a romantic embrace and asks what took him so long to reveal it to her, whereupon Clark is shocked by her already knowing the truth. (Isis)
Clark told Lois about his alien origins in the following episode. (Harvest)
- Clark told Jimmy he was the Red-Blue Blur after Jimmy had witnessed his wound healing instantaneously. (Doomsday) He referred to the episode Identity when Jimmy connected the Blur with Clark based on photos and Clark threw off this suspicion by getting Oliver Queen to dress up in a red-and-blue costume and save Jimmy from a mugging.
- Clark used his powers in front of Alec Abrams, who temporarily was converted into Warrior Angel, when he saved Chloe from falling off a skyscraper's rooftop. Alec, converted back to his boy shape, gave him an image he had painted of the red-blue Blur with "RBB" on his chest, but stated he would like the "S" better.
Other people discovering Clark's powers
Other people in Clark's life also tended to learn his secret over time, some of them have yet to even learn his full secret:
- Sam Phelan accidentally saw Clark stopping a bus that went out of control. He kept the secret and used it to blackmail Clark until he was shot during a robbery. (Rogue)
- Kyle Tippet saw Lex, who was under the control of Bob Rickman's handshake, shooting Clark with an automatic weapon, while Clark dodged the bullets. He promised to keep Clark's secret. (Hug)

- Roger Nixon spied upon Clark, discovered his secret and even found the spaceship. (Tempest)
He was shot before he could publish his discoveries. (Vortex)

- Chloe Sullivan discovered Clark's super speed and strength when Alicia tricked Clark into stopping a moving car while Chloe was watching. (Pariah)

- Kevin Grady, Lois Lane and Sheriff Nancy Adams learned Clark's secret after watching him save Chloe by catching two falling columns. However, all the three women had their memory wiped by Kevin. Since he only took them away a few minutes of memory, Chloe still remembered what she learned of Clark's secret months ago and earlier that day. (Blank)
- Arthur Curry saw Clark absorbing the explosive force of a bomb with his body. (Aqua)
He later became a member of the Justice League.
- Linda Lake, in the form of water in a bathtub, overheared a conversation between Chloe and Clark from which she learned that Clark was an alien. She prepared an article, but her computer was destroyed by Chloe and she was run over by a car before she could publish it. (Hydro)

In Season Eight's Abyss, Chloe's memory of Clark's secret was wiped and Jor-El, at Clark's request, did not restore it.

Lex learned that Clark was the Traveler from Brainiac (disguised as Kara) at the end of Season Seven, in Arctic.

- Season Three, Asylum - Lex has refrained from mentioning Clark's secret to anyone.

- Season Eight, Identity - Jimmy deduces that the "Good Samaritan" saving citizens of Metropolis is Clark. He confronts Chloe and Clark, who both deny it. Clark is adamant that Jimmy not confirm his secret, since he firmly believes that anyone that knows his secret is in danger. Clark enlists Oliver Queen's help in staging a rescue of Jimmy by the Good Samaritan, so that Clark has an alibi. Also, Sebastian Kane uses his memory-reading powers to learn Clark's secret: Chloe then kills Sebastian by overloading him with information, presumably downloaded from Brainiac.
- Season Eight, Abyss - Chloe's memories are being deleted by Brainiac, including her knowledge of Clark's secret. Clark brings her to the Fortress of Solitude to have Jor-El restore her memories: her memories are restored but at Clark's request, she has no recollection of Clark's powers or of Krypton.

- Season Eleven, Olympus - Clark reveals his secret identity to Diana in order to gain her trust and help her track down the creatures that attacked her and Lois prior.
- Clark's guilt over indirectly causing the 1989 meteor showers was behind his greatest fear: he feared that Lana would reject him once she realized "his" meteors had killed her parents. (Season Four's Scare) This part of Clark's secret has not been fully explored in Clark and Lana's relationship: by the time she discovered the rest of his secret at the end of Season 6, Lana had presumably already dealt with the death of her parents and was ready to move on.
- Jor-El showed Clark what would have happened if his ship had not made it to Earth: the 1989 meteor shower still would've happened, but Lex Luthor would become President of the United States and cause a nuclear apocalypse on Earth. This may have helped Clark overcome his guilt over his role in the first meteor shower.
- Clark's secret is sometimes perceived of as a burden by those who bear it. Pete told Clark that, "I walk around every day afraid that I'm gonna slip up." Pete moved away to Wichita, as he couldn't live with the risk that he might slip up and reveal Clark's secret. After Jonathan passed away, Martha was glad to learn that Chloe shared Clark's secret. (Vengeance)
- Both Chloe and Lionel found a sense of purpose after finding out Clark's secret, as well as were willing to do anything to protect him, including sacrificing their lives. Chloe refused to give up Clark's secret even while she was tortured and almost killed by Agent Vanessa Webber in Sleeper, Lionel refused to reveal the identity of the Traveler to Lex, who killed him in anger in Descent.
- Clark Kent is not willing to sacrifice people's lives to protect his secret. He tried to save Dr. Steven Hamilton even though Dr. Hamilton had learned his secret. Clark Kent was even unwilling to sacrifice someone's memories: Clark tried to prevent Lex from undergoing electroshock therapy to give him amnesia, even though Lex had witnessed him using his powers.
- Federal government agents have twice tortured Clark's friends, seeking to discover his secret. Chloe was tortured by Agent Vanessa Webber of the Department of Domestic Security, while Pete was tortured by FBI Agent Frank Loder.
- In Infamous, federal agents interrogated and shot at Clark in his house: they later started a manhunt for not only Clark but also Chloe, his best friend.
- Clark has revealed his secret and then "taken it back" three times. The first two times were with Jor-El's help twice. In Season Five's Reckoning, he told Lana his secret: after she died, he used Jor-El's time crystal to reset time. In Season Eight's Abyss, Chloe's memories are removed by Brainiac: Clark asks Jor-El not to restore her memories of Clark's powers or of Krypton. The last time, he revealed his powers to planet Earth, but then later went back in time using the Legion ring.
- After Clark's secret was revealed to the Earth, Martha was forced to temporarily step down as Senator for the state of Kansas. (Infamous)
- It's interesting to note that by the end of Season Eight, every character in the opening credits, except for Lois, learns Clark's secret. Lois learns the secret in the Season finale of Season Nine and retains that knowledge to herself in Season Ten (acknowledging that she was "the last one to know".) until Clark tells her his secret willingly and Lois reveals that she knows. As of Season 10, every main character in the cast knows about his secret from the premiere onward which is the first time in the show's history this has happened.
- The meteor freaks and human antagonists that have found out Clark's secret while trying to kill him are rumored to have told the others in Belle Reeve.
- Clark has revealed his secret to Lois purposefully on three occasions. He, under the influence of red kryptonite revealed it to her in Crimson. Since both were infected, she forgot when cured. In order to prevent Linda Lake from manipulating him, he revealed it to her again in Infamous so she could tell the planet but had to reverse the timeline so he didn't reveal it to her. He reveals it to her in Isis on his own, knowing she needed his honesty if they were going to share a life together.
- Clark has revealed his secret to three people as they were leaving his presence. He told Pete in Duplicity, who was driving off angrily because Clark had been lying to him. He told Lana in Phantom as she was leaving the barn, preparing to leave Smallville to get away from Lex. He revealed his secret to Lois as she was leaving the basement of the Daily Planet in disappointment because Clark had just said the Blur probably wouldn't reveal his secret to Lois as long as it put her life in danger.
- ↑ As revealed in Apocalypse, the meteor shower would still have happened even if Clark's ship hadn't made it to Earth.
- Secret Keepers - A list of people who have learned about Clark's powers (but don't necessarily know his full secret)..
