How do you save the world and not tell anybody? Terry:
I can tell you. You can tell me. That's why I'm glad you found out, partner.
Your hero has a dirty little secret
that is central to the character and the show's main plot. He might be a superhero, or he might have a lab in his bedroom
, or she might be a witch
. There will sometimes be one regular Joe who knows about the hero's secret, and will also keep it secret. The Secret Keeper can be family, though it's very uncommon for them to be parents
Often, the existence of a Secret Keeper is only hinted at, rather than explicitly revealed to either the hero or the audience.
The phrase originated
in Harry Potter
, where the Fidelius Charm
hides a secret within a living person's soul (that person would then become the "Secret Keeper"); everyone else in the world other than the chosen person would be unable to learn the secret unless directly told of it by the Secret Keeper. Even if they originally knew the secret, the details would become muddy in their minds unless reminded by the Keeper.

to keep a secret. See also The Confidant

that someone knows his secret, see Secret Secret Keeper

- In the classic anime Kimagure Orange Road, blood members of the Kasuga family all had psychic powers and a desire to keep them a secret from the general populace. This necessitates that anyone who marries into the family (such as Kyousuke's father) must become a Secret Keeper. The manga takes this to its logical conclusion that members of the Kasuga clan must reveal their powers to those they intend to marry before they can get hitched. Hopefully, if you love them enough to marry them, they like you enough not to blab your secret to the world.
- The other major secret that Kyousuke has - his budding love for Ayukawa Madoka - is kept by his sister Manami. In the manga, she even explains it to Hikaru, with the iconic "red hat" as proof.

A girl named Shouko Utakura finds her friend Sawanami dead and, due to his dying clues, she realises that their common acquintance Mifune is the murderer. However, Shouko is Mifune's Unrequited Tragic Maiden and decides to keep this a secret... but commits the huge mistake of actually telling Mifune that she knew the truth, but wouldn't snitch. Mifune, who had killed Sawanami because he was involved in his girlfriend's death and now believes Shouko had something to do with it too, thought she would denounce him anyway and few days later he strangles her to death.

Lelouch gains many more Secret Keepers as the second season progresses with the likes of Kallen and his own maid, Sayoko, but after the Grand Finale, only a handful of people in the world know that Zero has been replaced by Suzaku Kururugi.
- A case shows up in One Piece, regarding what really happened between Zoro and Kuma. Aside from Zoro himself, only three members of the crew know the truth: Brook, who saw it happen (since it's next to impossible to tell if a skeleton is conscious or not); Sanji, who heard it from the Risky Brothers and told them not to tell anyone else; and Robin, who used her powers to eavesdrop on that conversation. And Zoro only knows that Brook knows; the other two keep the knowledge to themselves because it would devastate Luffy if he found out, and Zoro didn't do it to be praised anyway.
- Also, the Gorgon Sisters. They would sooner die than let anyone find out that they were ever slaves to the World Nobles; only four known individuals have been trusted with the secret. The first three are Silvers Rayleigh, Shakky, and their surrogate mother Elder Nyon, who helped them get back to Amazon Lily after they escaped. And the fourth is Luffy, Hancock's love interest.
- A handful of one off characters in the Sailor Moon anime find out about one or more of the Sailor Senshi's identities, but they usually only show up in an episode each. The manga has a few more ongoing characters learn of the masquerade (most notably Motoki). It is implied in both during R/the Black Moon arc that Naru does know Usagi is part of something unusual and important but that Usagi doesn't want her to ask about it, so she complies to not put pressure on her.
- In Karin, the character Kenta Usui ends up pretty much strong-armed into becoming one for the Marker/Maaka family when he learns that their middle daughter Karin is a vampire.
- In Baccano!, Ronnie Schiatto serves as Maiza's secret keeper and only constant companion up until everyone in the Martillo family winds up immortal, and Maiza catches on that that Ronnie is a lot less human than he originally presented himself as, at which point the roles reverse.
- In Bakuman。, Moritaka Mashiro, after finding out that his fiancee Miho Azuki's mother Miyuki once loved his uncle, Nobuhiro, and that Miho is unaware of this, asks Miyuki not to tell her. She agrees and asks Moritaka's partner Takagi to do the same. This comes back to haunt Moritaka later, as Miho becomes angry with him for keeping it from her, and does not believe they should have secrets between them.
- In Mai-HiME, Takumi becomes one for Akira when he first finds out that Akira is the "secret ninja" protecting the school, and later when he finds out that Akira is female.
- Mobile Suit Gundam The Plot To Assassinate Gihren reveals that Cecilia Irene was the keeper of the keys for Big Bad Gihren Zabi. She knew all his dirty secrets, ran black operations for him, and kept a lid on anything that might hurt his public image.
- In Sakura-sou no Pet na Kanojo, Sorata is asked to keep one from Misaki regarding Jin. He finds out Jin wants to go to a university in Osaka, not a local one nearby where Misaki was going. Jin says he's going to tell her at some point, and asks him not to tell her about it.
- Then Misaki finds out about it anyway in episode 11, although it was Fuuka, Misaki's sister, casually mentioning it to Jin, who says she heard it from his mother. Although Sorata comes clean about knowing the secret, Misaki seems more excited by the fact that he turned down her sister, which mean she still has a shot with him.
- In Sekirei, a majority of the Single Numbers (with the exceptions of Tsukiumi and Akitsu), as well as Uzume, Seo, and the twins Hikari and Hibiki, are sworn to secrecy about the identity of the mysterious #01. It is Harem Nanny Miya Asama. The secret is kept primarily because they are terrified of what she will do to them if they let it slip. Even the Big Bad honors the secret, and leaves her alone.
- In Tonari no Kashiwagi-san Yuuto finds out about Kotone secretly being an otaku, which is what kicks off the plot. Sayaka, a Childhood Friend of Kotone, was already in the loop, and eventually more characters find out. Tina figures it out herself almost immediately when she notices the phone strap Kotone has, and Yuuto tells her to keep it a secret.
- In Private Actress, very few people know that Shiho Kobayakawa is the secret daughter of the famous actress Sayuri Nagasawa. Among them we have her nanny Makiko Mouri, her boyfriend and fellow P.A. Tomoomi, the Intrepid Reporter Matsumae, fellow aspiring actress and illegitimate child Mariko Soriarno and her Evil Counterpart Kana Juumonji/Satoka Ryoudou.
- At the start of Boku Girl, Mizuki's best friend Takeru is the only person who knows he's been Gender Bent into a girl. Later, Takeru's sister Mei is brought in on the full secret. Mizuki's roommate Yamada knows Mizuki is physically female, but thinks he's a girl masquerading as a boy. As far as Mizuki knows, the same is true of classmate Loki, though in that case Loki is the cause of the Gender Bender. As of chapter 38, Mizuki's crush Fujiwara has also been told the full truth.
- Superman's secrets have a surprisingly large number of protectors:
- In the Post-Crisis era, Lois Lane discovered Clark Kent's secret identity around the time they got engaged. Afterwards, Lois was a very able Secret Keeper. In the New 52 books, however, Lois, like her Pre-Crisis counterparts, doesn't know.
- Bruce Wayne is also one of Clark's Secret Keepers (as is Clark for Bruce). This led to an amusing sequence when Bruce assumed Lois knew his secret, because he didn't expect Clark to keep secrets from his wife, whereas Clark felt it wasn't his secret to share. By the end of the story Lois has become another of Bruce's Secret Keepers.
- Lana Lang, in pre-Crisis what-passed-for-continuity, sometimes knew Clark's secret and sometimes didn't. In some stories she knew it but was hypnotized to only remember it in certain circumstances (such as, for example, being in the 30th century as Insect Queen... yeah, the Silver Age was like that). One 1958 story even Deconstructed why (Silver Age) Lana would make a poor Secret Keeper when she tried to cook up a new secret identity for an amnesiac Superboy as her 'cousin Andy'. Unfortunately her attempts to cover for 'Andy' backfired badly and she later ruefully concluded she just wasn't "smart enough" to hang onto the secret without blowing it. Post-Crisis onward, Lana definitely knows since Clark told her and has been a special confidant to him ever since.
- Jonathan and Martha Kent started keeping Clark's secret long before he knew about it himself.
- Pete Ross discovered Superman's secret ID back when he was just Superboy during a camping trip. A convenient flash of lightning revealed Clark changing clothes, and Pete kept it secret, not even letting Superboy know that he knew. He once even used his knowledge to become an honorary member of the Legion of Super-Heroes by claiming he had telepathy and knew Superboy's secret ID. Writing the identity on a lead tablet so Superboy couldn't see. Superboy assumed Pete was bluffing and that everyone else was just going along with the joke.
- More people are in on Bruce Wayne's secret than one might expect:
- Alfred Pennyworth is his primary Secret Keeper. He knows things about Bruce that even Dick Grayson doesn't know.
- Lucius Fox is sometimes portrayed as most likely knowing that Batman and Bruce Wayne are one and the same, but not telling anyone, not even Bruce, this knowledge. In the recent movies, this was expanded to him explicitly knowing his secret and being in the loop.
- In "Hush," The Riddler reveals that he deduced Batman's Secret Identity while taking a dip in a Lazarus Pit. However, Batman convinces him to keep it secret for two reasons: first, having such a secret is no fun for an obsessive puzzler like him if every one knows it, and second, it would give the owner of the Lazarus Pits, the Big Bad Ra's Al Ghul, a vital clue that the Riddler used a pit without permission and have his League of Assassins kill him no matter where he is. More recently, the Riddler has developed a mental block preventing him from remembering this.
- "Hush" actually showed a lot of Batman Secret Keepers: two Robins, Superman and Lois Lane, the Huntress, Leslie Thompkins, Zatanna, Batgirl, Catwoman, Ra's and Talia Al Ghul, the Riddler...
- Jim Gordon is generally portrayed as being a good enough detective to have found Batman's secret, but reserved enough not to tell anyone, even Bruce, likely because it would put him in an uncomfortable legal position. In the first of the most recent Batman/Superman series, Batman, while noting the same thing about Superman's Perry White, reveals that he's aware that Gordon most likely knows.
- In one issue of Birds of Prey, Barbara Gordon revealed her operations as Oracle to her father, who was initially stunned but ultimately proud of his daughter. Barbara then pulled out her old Batgirl costume, saying, "I'm so glad that you're handling this so well, Dad, because there's more to it, I'm afraid." Jim Gordon's response: "Okay, this part I knew."
- Batwoman has her dad, Colonel Kane, who is also her main source of logistical support. Also, Renee Montoya and Nightwing deduce her identity in 52 (the former knows her quite intimately, while the latter comments that she has been leaving him clues on purpose as a sign of trust).
- Mary Jane Watson was Spider-Man's Secret Keeper, then Aunt May until that entire "One More Day" thing happened.
- MJ is still Spider-Man's secret keeper. They're just not romantically involved at this time.
- Then again in Ultimate Spider-Man, including former bully Kenny McFarlane. Kenny actually figures it out on his own, staying up late at night, thinking about Peter's new awesomeness (ie: he flipped Kenny once, broke Flash's hand, replaced Flash on the basketball team, etc.) and Spidey's apparent availability at Midtown High School. Then he tests it. Cue the subverted Bruce Wayne Held Hostage.
Peter Parker: (to himself, while he's loading books in his locker) What the-? Oh, come on... My Spider-Sense is going off at school. That can only mean one thing. And the Academy Award for best performance by an amateur super hero trying desperately to hold onto his secret identity goes to...
Kenny: [kicks him into the locker]
Peter Parker: Ow! Owy ow! Why did you- ow! What is wrong with you!!?? Ow- Owww!!
- Miles Morales, the new Ultimate Spider-Man, shared the secret of his powers with his friend Ganke.
- Aunt May seems to play this role in the Spider-Man Trilogy movies, particularly the second movie, where she gives Peter a speech seemingly directed at Spider-Man, which helps him decide to become Spider-Man again.
- Aunt May definitely plays this role later in Ultimate Spider-Man. With that awesome matriarchy, Aunt May subverts There Are No Therapists. At one point, she pulls a gun on a recognized supervillain.
- Jaime Reyes, the current Blue Beetle, was thrown a year into the future after Infinite Crisis. His family, naturally enough, freaked out on his return, so Jaime decided to prove his story about what had happened to him by revealing his secret identity. His family and friends know, but keep it a secret outside of that.
- The second Blue Beetle, Ted Kord, had his girlfriend Tracy as a Secret Keeper during his Charlton incarnation.
- It's revealed in DC Comics' Identity Crisis, that all the superheroes (the ones whose identities remain a secret) know each other's identities.
- Whether or not the superheroes' secret keepers are aware of the others are open to debate. Especially considering that Jean Loring knows Tim Drake is Robin, despite Tim having his identity a deep secret even from Bruce's allies.
- Wesley Dodds' girlfriend Dian Belmont knows he is the Sandman, and occasionally helps him in his cases.
- Green Lantern Hal Jordan's first Secret Keeper was his airplane mechanic, Tom Kalmaku. When Tom accidentally learned Hal's identity, he respected GL enough to offer to let him erase the memory from his mind—but the offer convinced Hal that Tom was trustworthy, so he let him keep the knowledge and they became close friends.
- In a villainous example, the Kingpin kept Daredevil's secret for years, to the point that among his goons, it was well known that he knew exactly who DD was. However, a no-name criminal decides that this is unacceptable, since Daredevil still ruins criminal operations, and thus, Kingpin is indirectly responsible for the losses other gangs have suffered. Thus, the upstart turns all of Fisk's goons against him.
- In Kyon Big Damn Hero, Rika and Kyon are this to each other, Miyoko/Miyokichi inadvertently became one, and Kyon's sister wants to become one.
- So far, quite a few members of the extended SOS Brigade trust Kyon's sister, but Kyon himself doesn't trust her.
- In the Mass Effect Self Insert Mass Vexations, Tali eventually becomes Art's secret keeper.
- He gets a lot more secret keepers in the sequel: as of the moment, Garrus, Madison, Thane, Kasumi, and Shala'Raan have all found out.
- In the Elemental Chess Trilogy, it gets revealed that Maes Hughes was this for Roy Mustang and Riza Hawkeye, before and during the early part of the Fullmetal Alchemist canon. Hughes, who was Mustang's best friend, was the only one who had absolute confirmation of the actual relationship between the two (though plenty of other people guessed).
- A Brief History of Equestria: Prior to the birth of Pansy's son Plow Blade, the only pony who knew about her relationship with the Earth Pony Trencher was her friend Shield Skin, who they even used as a secret messenger. This lasted for years, until Plow Blade's birth — since he was an Earth Pony like his father, Pansy was forced to admit the truth, leading to Hurricane trying to arrest and kill Trencher, which kicked off the Winter War.
- There are two examples in A Growing Affection:
- The five Kages and the leaders of three Kekkei Genkai clans (one of which is Hiashi, the other two are unrevealed) hold the secret origins of bloodline traits.
- Tsunade and Jiraiya, with Kakashi and Shizune as backup, keep the secret of Naruto's father's identity.

- Mare of Steel: The rest of the Mane Six, Princess Celestia, and Rainbow Dash's mother Firefly become this for Dash when she becomes Supermare. Thunderlane joins the list when he figures out her identity during her final fight with Brainiac.
- In one of the side stories, she and Batpony become this for each other when he deduces her identity, and she uses her X-Ray Vision to see that he's the real Prince Blueblood (who was kidnapped and replaced by Zod.
- The Elements of Harmony and the Savior of Worlds: Celestia and King Spykoran are the only ones aware that Spike is Spykoran's long-lost grandson. They agree to keep the secret for the time being, because they can tell he's quite happy with Twilight.
- A Hairier Problem Rise Of The Furball: The Cutie Mark Crusaders initially become this for Apple Bloom when they witness her first transformation into a werewolf. Babs Seed later is introduced to the secret after accidentally witnessing it herself, and Silver Spoon has to keep it as well following her Heel-Face Turn. The other new lycanthrope, Lightning Dust, has keepers in Rainbow Dash, Applejack, Fluttershy, and Twilight, but thanks to a slip-up by Rainbow on Nightmare Night Rarity, Pinkie Pie, and Spike learn her secret as well.
- In Mega Man: Defender of the Human Race, ProtoMan is this for the fact that Nomad's alive.
- Cut Man, Guts Man, and Magnet Man are this for ProtoMan meeting with Nomad.
- MLP Next Generation: Know Fear!: Sunny Skies is the first pony to find out Starburst's Secret Identity as the Fear Lantern, and agrees to stay quiet on it both out of respect to their friendship, and because she feels she owes Star for saving her life in Stalliongrad. This ends up becoming a moot point, when Starburst ends up outing herself as the Lantern while in her rush to save her mother.
- In Origin Story, many people think they know Superwoman's Secret Identity. She get's called "Karen Starr" all the time by various people. Thing is, Superwoman's real name isn't Karen Starr... its Alexandra Harris. Alex's domestic partner Louise and the members of The Runaways function as Alex's Secret Keepers.
- Patrick and Grace Winslow play this role in The Smurfs regarding their little blue visitors from another time and place, because, hey...who would believe them in a world that seems to regard the Smurfs as a mere legend documented by a Belgian cartoonist?
- In The Unknown, Cojo the midget knows Alonzo's secrets (that he is a murderer and that he is not really armless) and helps him maintain his cover in the circus.

- The last episode has Tori.
- Keely in Phil of the Future.
- Harper in Wizards of Waverly Place.
- Justin's best friend, Zeke, becomes this in season 4.
- The family (yep, her parents too) of Raven from That's So Raven, is fully aware of her secret Psychic Powers, most likely even before she was. These were later revealed to be a hereditary trait. The ability is treated serenely since the very first episode of the series, despite the sitcom-y mishaps that regularly occur because of them.
- It's also played straight with Eddie and Chelsea.
- On Torchwood, Rhys Williams (Gwen Cooper's fiance), stumbled onto proof of just what it is that Gwen does for Torchwood. Captain Jack Harkness decides to not dose Rhys with Retcon (Torchwood's amnesia pill) after he sees how much good it does Gwen to have someone outside of Torchwood to talk to about work.
- In Dexter, Harry, Dexter's foster father, is the typical example. The second is the Ice Truck Killer, Dexter's nemesis, who is appropriately revealed to be Dexter's biological brother.

- On Bewitched, Darrin Stephens acts as a Secret Keeper for not only his wife, Samantha, but also for his mother-in-law, Endora, her father, Maurice, as well as Samantha's many aunts, her Uncle Arthur, and Samantha's witch-doctor, Doctor Bombay, all of whom interact with various mortals during the course of the series.
- The writers of Smallville have had to let so many people in Clark's secret to keep the show fresh that Lois Lane is about the only one who DOESN'T know by now. Clark told Pete his secret in season two when the latter discovered his spaceship, Alicia revealed Clark's powers to Chloe in season four and Chloe tells him she knows in the season five premier, Lionel found out in season five, Lana started causing trouble around season six and found out in the finale, Lex found out in the season seven finale but was then Put on a Bus.
- Lois seems to know now and is currently a Secret Secret Keeper as Chloe was before her.
- As of the episode "Isis", it's official; Clark confessed that he's the Blur to Lois, who responded by jumping into his arms, kissing him and asking, "What took you so long?"
- Though it did take even longer for her to find out about the Justice League, which led to some particularly funny moments, like when Tess, despite knowing that Lois knows Clark's secret, still plays dumb because Lois doesn't know that Tess knows (and more than she does to boot). The first part of season ten gets a bit confusing at times.
- Tess was a Secret Keeper as well, which was particularly important since she was one of the bad guys, yet she still kept his secret from everyone. She had a Heel-Face Turn, though.
- Pushing Daisies: Emerson and Chuck are keeping Ned's secret that he can bring the dead back to life, while Ned, Emerson and Olive are keeping Chuck's secret that she's not dead, but Olive thinks that Chuck faked her death whereas Ned and Emerson know that she did die and was brought back.
- Also, Olive eventually becomes Lily's secret keeper, hiding the fact that Chuck is actually Lily's daughter, not her niece, conceived during an affair with her sister's fiance. Olive gets so overwhelmed by all the secrets that at one point she runs away to nunnery.
- Gaius from Merlin is the only person (as yet) in town who knows about Merlin's powers, as well as being his mentor.
- Lancelot knows too, but has agreed to keep it a secret.
- Likewise, Merlin is Lancelot's Secret Keeper: he's the only one who knows that Lancelot is still in love with Guinevere.
- On the same show, Gaius, Merlin and Gwen are the only ones that know Morgana has precognitive dreams.
- Inverted in regards to Morgana in season 3. For the first half of the season only Merlin and Gaius know the secret that Morgana is evil, but they are unable to tell anyone about it without any proof, despite dearly wanting to warn their friends. The same thing happens with Agravaine in season 4. They both reveal themselves as traitors.
- In season 5, Mordred and Merlin are this for each other, as they're both warlocks.
- The wives of The Unit.
- In Psych, the only people who know that Shawn Spencer is a Phony Psychic are his father, Henry, and his best friend, Gus.
- That's debatable. Lassiter claims to not believe and wants to expose him as a fraud, even hooking him up to a polygraph machine (which Shawn beat due to his father's extensive training). It would seem Da Chief doesn't believe it either, but Shawn is really good at solving crimes, so she doesn't care how he does it.
- As of Season 5, there is also amateur profiler Declan Rand and, oddly enough, Curt Smith from Tears for Fears.
- And as of Season 7, Juliet finds out, at first reacting in anger but eventually resolving to keep the secret once Shawn proves that he cares more about her than anything else, including his work at the SBPD. She also realizes that the cases he solved might be jeopardized if he told the truth about it.
- The Power Rangers series in general has a tendency for family members of the rangers to find out their secret identities; in these cases, they only appear in one episode. Some examples include:
- In Power Rangers Zeo, Red Ranger Tommy's brother David.

- Power Rangers Mystic Force has Toby, the rangers' boss at their civilian jobs, but he doesn't find out until the fourth-to-last episode…though they did use a Sarcastic Confession on him at an earlier point to explain why they continuously ran off during their shifts. Subverted, however, in that he pretty much tells the whole town in order to gather enough energy to give the Rangers the final boost in power that they need to destroy the Big Bad.
- Buffy the Vampire Slayer:
- The Scoobies are Buffy's Secret Keepers, but they all stretch the definition of "normal". Many of the Scoobies start outside the fold as "normals" and eventually get pulled in to Scoobiedom (Cordelia, Oz, Tara). Another example would be Buffy's mother Joyce after Season 2.
- Principle Snyder knew about the existence of the Hellmouth all along - and was even charged to keep it a secret from as many people as possible by the Mayor himself. That said, he was completely oblivious to Buffy's identity or the Scooby Gang.

- Warehouse 13: It's far from unheard of for an outsider to discover the Warehouse in some way, but it hasn't been made into a major plot point yet; as of yet, most of the outsiders that have learned enough to be a threat have either been recruited or killed; the only known exceptions as of yet are Claudia's brother, Mrs. Frederic's grandson, and Monty the Magnificent, an elderly magician that was let in on the secret due to his passion for "real magic." However, the series also has a Chekhov's Gun that has yet to be fired: each Warehouse agent is allowed to reveal the true nature of their work to exactly one living person. But as was said earlier, it hasn't been made into a major plot point yet.

- In the second game of the Eagle Eye Mysteries PC Edutainment Game series, protagonists Jake and Jennifer Eagle, as well as your unseen player character, become Secret Keepers in "Case of Blood's Bold Bauble." A distant relative tells you that there's a particular story that has been kept within his immediate family for generations: that three centuries ago, an ancestor found a small but very valuable ruby that was dropped by the titular thief Captain Blood and his gang, who beat a hasty retreat after attempting to break into the Tower of London to steal the Crown Jewels. The ancestor, fearing he would be implicated in the robbery if he tried to return the ruby, kept it for himself and only told its story to his son, who in turn told the tale to his son, and so on. By the time you, Jake and Jennifer have been told the story, the secret's origins are so distant that the ruby's revelation can no longer hurt the family; the only reason the relative tells you the story is because he thinks one of his three children, who are currently the only other people who know the family secret, might have broken the bond of parent-child trust and told the secret to cash in on it—hence, the beginning of your covert investigation to find out who's responsible without tipping off any of the children as to your knowledge. Turns out none of the kids talked—the oldest son is set to star in a film about a very different Captain Blood, and the misunderstanding arose from that.

- Lawyers (at least in the United States, the United Kingdom, and some other common law jurisdictions). While there are a few exceptions to attorney-client privilege (generally having to do with preventing reasonably certain serious bodily harm), for the most part, an attorney can't reveal anything that their client tells them in confidence. This means that in most, if not all, U.S. jurisdictions that if an attorney find out their client committed a crime that an innocent person's in jail for, their ethical obligations to their client prevent them from saying anything without their client's permission, even if the other person is serving a life sentence. Keeping Secrets Sucks.
