Secret Legacy

"The hero is in dire straits, on the ropes from the Giant Mook's relentless attack, when who should come and save him but... his mom?"

Heroes are a lonely lot. Whether a Superhero, psychic, the Last of His Kind, or an Ignored Expert fighting uphill for the sake of the ungrateful masses, heroing is a solitary and unpopular path that separates one from all other Muggles and even loved ones. His own family can come to reject the hero, denying their approval or outright scorning him as a freak, it's not like their career choice is following the ancient family legacy. Or is it?

Despite growing up with an otherwise mundane childhood with nary an inkling of the extraordinary, our hero jumps into the thick of things and becomes a hero, or is a Weirdness Magnet and thrust into adventures he can barely fathom. A ways through the series, they'll find out that they're actually heirs to a Secret Legacy of heroism. Maybe it's an old ally of their parents, the parents themselves (though a lot of the time, the legacy is from the father's side), or discovering a hidden cache of artifacts and weapons that belonged to his parents. In any case, characters who have a Secret Legacy are heirs to a family tradition of unusual and heroic proportions. Crime fighting, archaeological adventure, and super heroing are just some examples. Maybe it's "Genetic" or In the Blood, but more often than not it's adventure that finds them, or simple common nature with the parents that leads to the hero picking up his birthright.

For whatever reasons, the hero's real or Muggle Foster Parents chose not to tell him of their real job or former adventuring and keep him Locked Out of the Loop. Some reasons could be to forget the past, to protect him from their enemies, to raise him in a "normal" environment, to prevent his repeating the folly of dead relatives, or because they died. Whatever the specifics, from the point they reveal their Secret Legacy onwards they'll serve as mentors and occasional backup. A Secret Legacy can be used to add depth to a character's background, for cheap laughs, or to give them a support network capable of helping fight bigger threats. Occasionally, both sides will be in a double blind situation where neither knows what the other is up to.

Note, this can happen with the Villain's kids too. This can result in a Living with the Villain situation if the kids get recruited to the other side before the parents tell the kid what's going on. Occasionally the parents won't know about their child's real job outside the Burger Fool thanks to a Secret Identity, so you have a double blind situation which at least justifies why they made him struggle alone with his powers and adventures, forcing him to figure it out himself.

Compare Rags to Royalty, when the legacy is monarchy. May be passed on as an Unexpected Inheritance.

Anime and Manga

 * In Bleach, Ichigo's dad turns out to hold captain-level spiritual power. Pretty crazy considering they make him out to be an idiot.
 * Ishida's dad follows the trope even more, revealing himself to be an active Quincy after all, and showing up to save Ishida's ass after he's lost his powers.
 * In Gate Keepers, Shun eventually learns that the reason his supposedly neglectful father was hardly ever home was because he was a Gate Keeper, too.
 * The manga Initial D. A character is left in the dust of an old Corolla, something he is understandably annoyed about, as he is riding an RX-7. He rides to a nearby gas station the next day to see if they know about the rust bucket, where the manager of said station implies that the only car fitting that description belongs to the main character's father, a local racing legend back in the day. The main character, however, couldn't care less about this bit of information (or about anything else at the beginning of the series.)
 * The main character of Naruto is eventually revealed to be part of a line of people linked both by blood and Mentor ship who have been the leaders of the village since its foundation.
 * That's on his Fathers side, on his mothers side we have all the nine tails jinchuuruki.
 * his mother's side are also distantly related too the first two hokages and the first nine tails jinchuuruki being marred to the first hokage.
 * In One Piece, the people with "D" in their name are said to have "The Will of D." They all seem to share similar characteristics (being Big Eaters, having their own sense of justice which they doggedly pursue no matter who is in their way, and smiling at their deaths) and their actions tend to have far-reaching consequences (Luffy's being most apparent in his various adventures, but others such as Jaguar D. Saul saving Nico Robin who is now the only person who can read poneglyphs and seeks to discover the mystery of the Lost One Hundred Years have cropped up), not to mention Gol D. Roger, the Pirate King, who turned the world upside-down with his legendary feat of reaching the end of the Grand Line and his proceeding actions that led to the start of the Golden Age of Piracy.
 * This legacy is so secret that not even those who carry it know what it means. Luffy and Saul don't even get the reference when asked about the D. This makes Roger notable as the only D (thus far) who actually knew what it meant.
 * Magic Kaito is about the main character finding out about his father's secret identity and taking up the mantle. In aversion of the normal plot, the reason this was kept from him isn't any of the usual reasons, it's that the identity is that of a gentleman-thief, and so everyone keeps it a secret. His mother even knows, and is completely accepting of him taking up his father's mantle, even though it eventually got his father killed. He even has the rest of his father's support network working with him and some of them don't even know it's a different person now.
 * The one reason that he doesn't exactly like it is that his best friend and love interest hates his secret identity, and her father is the police chief in charge of catching him.

Comic Books

 * Marvel's Runaways series embodies this trope pretty well.
 * May "Mayday" Parker in the MC2 continuity fits this perfectly.
 * Jacob and Miller find out that their mother was the worlds greatest supervillain in Necessary Evil.
 * In the earliest version of the Superman story, Clark knew that the Kents had found him in a rocket ship, but had no idea where the ship came from, nor any inkling of the heroic legacy of his father, the original Jor-El. During the Silver Age, Kal-El came to Earth as a toddler and had Total Recall of his days on Krypton. In the Christopher Reeve movies, the Timm/Dini animated series, Smallville, and the Post-Crisis Ret Cons, he didn't even know about the space ship until his powers developed to the point where his adopted parents couldn't just dismiss them any more.
 * In Wanted, Wesley's father was The Killer, a member of the Fraternity, a worldwide group of Supervillains. As expected Wesley has no idea about this, since his father left him and his mother while he was still young. It is revealed to him after his father is killed, since his father left everything he has to him, on the condition that he takes up the mantle of The Killer.
 * Spider-Man: Peter Parker's real parents were actually special operatives, which is why his camera was automated.
 * William Warlock from I Hunt Monsters finds out about his just as the monsters he's supposed to keep sealed break out from their prison.
 * Played with in Invincible. Mark Grayson knew all his life that his father was an alien superhero and Mark would probably inherit his powers. However, Mark didn't find out until he began his own superhero career that his father was a scout for a race of conquering alien Nazis.

Film

 * George Lucas likes to use this for some reason.
 * Indiana Jones and his father Henry Jones in Indiana Jones and the Last Crusade
 * Indiana Jones and his son, Henry "Mutt" Williams in Indiana Jones and the Kingdom of the Crystal Skull
 * Star Wars plays this trope straight and subsequently subverts it in that Luke's father is Darth Vader and lampshades it by having Yoda's last words being to tell Luke he has a sister.
 * In Wanted, the protagonist Wesley is told that his father (who left his mother the first week after his birth) was actually an assassin and was killed by an evil man named Cross. Wesley endures harsh training to kill Cross, but Cross unexpectedly saves his life. That doesn't stop Wesley from
 * The second two Ocean's Eleven movies use this with Linus Caldwell's parents. In Twelve, his mother appears as a police officer, takes over the investigation of his crime, breaks him in the interrogation room, and we are treated to a stunning reveal in the cars on the way out of the station. In Thirteen, his father turns up and pulls a very similar stunt. In both cases, the twist works only because we don't know who these police officers are and they are introduced as if their credentials are valid.
 * In the second film, Isabel's father was a thief who taught her everything he knew. She later becomes a cop and starts using that knowledge to catch thieves, including the famous Gaspar LeMarque. In the end, she finds out that LeMarque is her father.
 * In The Mummy Trilogy, Evelyn is a quiet librarian who claims her mother was an Egyptian. She mostly plays the role of a damsel in the first movie. In the sequel, she gets upgraded to an Action Girl, which is revealed to be due to her being the reincarnation of an Ancient Egyptian princess. Given her heritage, it can be assumed she is descended from the princess. Also, her husband is actually descended from a Medjai tribe.
 * Stop! Or My Mom Will Shoot

 * As Harry figured out, to be eligible to be a Knight of the Cross, one has to be the descendant of royalty. Since most people don't know whether they are partially royalty, Knights of the Cross are this.
 * In the Codex Alera... guess who. No, really. Go on. We'll wait. It was Tavi, in case you were wondering. He has the dubious distinction of being the one and only normal guy in a world where everyone has Elemental Powers. He proceeds to save the world repeatedly anyway through a combination of badassitude, intelligence, and leadership skills. It turns out that in this last especially,

 * The entire Royal line of Valdemar is secretly descended from Vanyel, the Last Herald-Mage, through a bargain struck to preserve the continuity of the Monarchy during a time of major political upheaval. This is crucial to the plot, as his descendant, Princess Elspeth, takes up the mantle of being Valdemar's first new Herald-Mage six hundred years later. She subsequently meets up with yet another descendant of Vanyel, Firesong K'Treva of the Tayledras—in fact, he's the one who tells her, as the Hawkbrothers were the only ones Vanyel entrusted with the knowledge outside of the inner Royal circle.
 * In the Army of the Sun trilogy, the main character is an orphan whose mother told him that he was born from a one-night stand with a crewman on a spaceship. In the third novel, he finds out that he is the direct descendant of.

He is being hunted by the previous Dragonslayer who now believes that it is necessary for a Dragon to survive. In the end, Victor has a vision that reveals that his strange grandmother is actually from the Middle World and was banished by the Dragonslayer after being raped by him (It Makes Sense in Context), making him the guy's grandson.

And then it's the discovery that her mother was a double triple quadruple -- okay, at this point, we have no idea WHO Irina was working for—agent up to her eyeballs in Rambaldi.

When her mother overhears, Yuki covers by saying they were discussing an Anime. The next two strips feature Meimi wondering about the silliness of Magical Girl shows
 * Yuki's father is in on the secret, too; unfortunately, having an ex-Magical Girl and a Magical Girl-to-be in the family meant his Magical Girl Detector alarm kept on bugging him, which meant he had to keep it switched off, which meant that when Yuki's powers actually did manifest, Inspecter Sonoda was a little unprepared...
 * Girl Genius is all this, with Agatha initially not knowing she's a child of an incredibly well-known hero and his less-well-known-as-the-ultimate-evil wife, or that her adoptive "parents" were also a well-known pair of heroes.

 * Up until Billie Wilson got her superpowers, she had no idea that her parents were superpowered mutants who work for the C.I.A. Or that her annoyingly-perfect older brother was a superpowered mutant with a low-level Paragon power. Or that her incredibly annoying kid inventor younger brother was also a mutant. Okay, her brothers were also clueless on this until she manifested and became Tennyo. (On the other hand, Jadis Diabolik has known about her father since she was old enough to keep a secret, because he is one of the most wanted supervillains on the planet.)

Western Animation

 * Kim Possible's Nana was resented by Kim, primarily for criticizing her clothes as too revealing and saying her world saving was just a phase, and that she'd grow out of it. What Kim's father never told her, but Dr. Drakken somehow knew, was that in The Sixties Nana studied with the Shaolin monks, was a top-rated aviatrix, and was the first woman to pass the Navy's underwater demolitions training course. He then uses a mind-controlling hearing aid to force Nana to fight Kim, a fight Nana wins.
