People who imply they're friends with their own Secret Identities in Fan Works.
Crossovers
- In Neither a Bird nor a Plane, it's Deku!, Hisashi Midoriya says that he works near where Firestorm operates and that he's had to deal with the New York branch of the Hasigawa Family when the topic of the Yakuza is brought up at the U.A. Culture Festival.
- The Secret Return of Alex Mack: Downplayed; Alex doesn't claim to personally know Terawatt but publishes the first clear video of her, and claims to have been trying to get a scoop on her for six months, so she's widely known to be associated with Terawatt. Danielle Atron joins the wrong dots, concluding that Alex saw Terawatt get her powers and knows who she is.
- Twice Chosen: In order to protect their secret identities, the Rangers plan to stage a broadcast after Rita's defeat pretending that they rescued the missing Tributes. This includes showing themselves in front of the Zords while they're being remote-controlled by Alpha.
- Curiosity Made the Cat has Shinichi get turned into a cat by the apotoxin. When Kaitou Kid hears Conan yowling as he transforms back into a human, he asks Catastrophe about him, with Catastrophe reassuring him that "He's fine. He's one of mine. I trained him to bring you here."
- This later backfires when Kaitou Kid decides that the best way to get Catastrophe's attention is to grab Conan, much to Shinichi's frustration.
- In Iron Touch, criminal counterfeiter Lovestrong introduces himself as Lovestrong's assistant to Michelle and Hol Horse (and therefore, the reader). It's not until Chapter 17 that it's revealed that the two of them are the same person, and only because his friend and contractor Depeche Mode refused to play along with the alias.
- In A Little Red and Blue
where Sharon Carter ends up getting transported to the year 1944 after an encounter with Wanda Maximoff. She later meets the past Steve Rogers and finds out that during this time, he was attempting to hide the fact that he is Captain America from the general public and claiming that he's just a soldier assisting the Captain. Steve becomes attracted to Sharon (who introduces herself to him as "Kate" and hides the fact that she's from the future) and has some difficulty hiding it when speaking to her in his Captain America guise, even kissing her at one point, all the while being unaware that "Kate" knows that he and Captain America are the same person.
- Tends to crop up in some Salt Fics; after falling out with her Fair-Weather Friends, Marinette will hint or even outright reveal that she's close to Ladybug, and that she personally recommended several of her former friends to serve as temporary heroes. She commonly backs up this claim by reminding Alya how she helped arrange her first interview with Ladybug, or revealing her brief stint as Multimouse.
- A Lady's Scout (and the Salt within her Soul) has Marinette subtly implying to her classmates that she's got some kind of connection to Ladybug by giving each of the temporary Heroes a piece of clothing themed around their alter ego... right around the time that they're replaced by other bearers, making them look like consolation gifts. When Lila attempts to drive a deeper wedge between her and Alya by implying Marinette might have had something to do with Rena Rouge getting replaced, many of her other classmates start trying to cozy back up to her in hopes she'll point Ladybug their way.
- LadyBugOut: Marinette knows that Ladybug starting her own blog will open her up to people tracing the blog back to its origins. In order to protect her secret identity, she posts a video where Ladybug introduces her as a friend helping her set up and maintain LadyBugOut.
- Miraculous Two Weeks: When Chat Noir realizes that Marinette must have seen Ladybug transform, she convinces him that the other girl is her Secret-Keeper. He subsequently tries to convince them both to let him make Adrien his secret keeper, so that they both have civilian contacts through which they can communicate with each other.
- Inverted in Now Kiss, where Chat Noir and Ladybug are pretending to be friends of Adrien and Marinette, respectively, so that they can talk with each other about themselves.
- In Rate This (Trust is Hard to Come By), the akuma Gardener unleashes her own version of Ladybug's Miraculous Cure, revealing how much (or how little) the heroine trusts every single person in Paris. Marinette's score is naturally quite high; when Alya furiously demands to know why, Chloé reminds the Ladyblogger that Marinette was the one responsible for arranging her first interview. Marinette rolls with this and informs her classmates that she's been showing her alter ego all of the nasty messages they sent her before she changed her number.
- Scarlet Lady has Chloé constantly claiming to be best friends with her own alter ego. She keeps up the ruse on both ends; Scarlet Lady often goes out of her way to reassure everyone that she personally made certain that Chloé made it to safety.
- Originally, nobody believed Chloé, assuming she was just fishing for attention. When Scar publicly declares it during the "Despair Bear" incident, it has a serious impact on how the rest of the class regards Scarlet Lady, since Chloé is Hated by All.
- Chloé also notably does not take it well when Lila tries claiming that she's close to Scarlet Lady, going out of her way to completely humiliate the other girl.
- This comes back to haunt Chloé when Sabrina barges into her bedroom during "Party Crasher", demanding that she contact her "lazy so-called best friend" and point her towards the latest akuma attack.
My Little Pony: Friendship Is Magic
- How To Win Enemies And Influence Ponies: So far as the world knows, A.K. Yearling is simply Daring Do's public relations agent, rather than her alter ego.
- A Moon and World Apart: Variant in that it's a friend who's in on the secret making the claim — in chapter 11, when Twilight, Sunset, and their new friends meet Princess Cadance in her public disguise of "Love Hearts", Sunset says that "Love here and my old foalsitter Cadance are real close". Cadance reveals her true identity to all of them just two chapters later.
