I Am Who?

"Hagrid:"Yer a wizard, Harry." Harry:"I'm a what?""

- Harry Potter and the Philosopher's Stone

The main character must be special somehow. The hero who would save the world cannot be just a farmer's son. In the rare case that the hero is not prophesied to do something or the current villain's relative, he or she is probably a powerful being, even a god, but does not know it.

The reason the character's true identity is hidden may range from simple lack of knowledge to a forced, magical amnesia. In this kind of story, this revelation is often the plot's main twist.

Often, this is an Awful Truth that must be withheld at all costs, because the character is unlikely to be able to control their immense powers or use them responsibly at this point in time, or ever.

May lead to Amnesiac Dissonance; may overlap with Luke, I Am Your Father in case the character is a god's relative. A particularly nasty revelation — for example, a Robotic Reveal — may drive the poor protagonist utterly mad. If it's not the protagonist who's secretly special, then this is King Incognito.

Subtropes include Amnesiac God. Often the result of a Changeling Fantasy. Related to Tomato in the Mirror. If everyone else knows the truth, the hero's been Locked Out of the Loop. Unrelated to I Am Not Who.

 * In Osamu Tezuka's Metropolis, Tima is a robot that was designed to run the Ziggurat, a weapon capable of controlling all mankind. The only one's aware of this fact are Dr. Laughton who is killed in the first few minutes of the film, Duke Red who commissioned Tima to be built, and Rock who wants Tima destroyed.  This is a trope namer as this question is Tima's first words in the film.

 * Superman's origin in more recent decades has this element. He gets a mostly normal early childhood, then starts developing special abilities then eventually encounters or is told about his rocketship which also eventually transmits a message or series of messages from Jor-El which usually tells him he has a great destiny.

 * After at the end of new series 4,  Of course, for Tennant's "going-away" episode,

 * The Doctor wasn't the only Time Lord to do this. Of course,
 * Parodied in a sketch on The State. The priest and nuns at a Catholic orphanage tell a young man on his eighteenth birthday that he's really a super-human alien from another planet. They tell him to "go out there and fight for truth and justice", and he jumps out the window...and falls. They then proceed to laugh their asses off, then decide to "do another one before lunch".

Oral Tradition

 * Many variants of the Arthur myth have King Arthur raised as a much lower-ranked if not common boy before proving himself in battle and being told of his lineage, or finding out upon the whole "sword in the stone" business.
 * Older Than Feudalism, from Classical Mythology: Paris or Oedipus the King, who were both prophesied to bring destruction and so were brought up as peasants instead of princes. Naturally, this didn't thwart their destinies. Oedipus's revelation was possibly the biggest tragic Heroic BSOD in theater ever, and led him to gouge his own eyes out.
 * The play about Oedipus has him raised by another king. His hamartia (Tragic Flaw) was his uncontrollable temper that drove him to club his father to death at the crossroad, to disregard Teiresias, and to jump to conclusions about Creon. His I Am Who? moment segued beautifully into his Heroic BSOD and exile.
 * Theseus, also. The son of Aethra (herself the daughter of a king) and King Aegeus (and also the god Poseidon ... however that works), he was only told his true heritage when he was strong enough to lift a massive boulder and reveal Aegeus's sword.
 * Actually, smart enough. The point was that the boulder was really too massive for any single man to be likely to lift it up and move it. Theseus uses a fulcrum and a lever to begin his Guile Hero career.

Tabletop Games

 * The White Wolf Tabletop RPG Scion is based on the concept that the player characters are the children of the ancient Gods from various pantheons (Greek, Norse, Egyptian, Japanese, Aztec, and Voodoo are in the main book; an expansion pack is available for Celtic, Chinese, and Indian pantheons).
 * And Scion's progenitor-game Exalted leaves the groundwork of this available to every single last one of the Celestial Exalted, each of whom has lived lifetime after lifetime of epic awesome heroism (in the classical Greek sense), but only allows the current incarnation at best partial recall of his legacy

Video Games

 * Baldur's Gate: The main character is revealed to be.
 * Beyond Good & Evil: With very little in the way of fore-warning, game throws you this curve-ball in the last act.
 * We'll be seeing it soon enough.
 * Neverwinter Nights Tales of Arterra, in which the player is . Also The Bastard of Kosigan, with.
 * Neverwinter Nights 2, when the Spirit-Eater Curse is explained.
 * Knights of the Old Republic: The main character is.
 * The Elder Scrolls III: Morrowind. The main character, a former prisoner and a spy for the Empire, is revealed to be.
 * Two sequels later, in The Elder Scrolls V: Skyrim, the Player Character eventually finds out that they are a Dragonborn; a prophesied being where a dragon soul ends up in a mortal body. Handy, since there seems to be a bit of a Dragon problem in Skyrim, and the Dragonborn is the only one who can permanently kill dragons. That, and the dragons' leader Alduin the World Eater isn't the only existential threat to the world at the time.
 * Arcanum: Of Steamworks and Magick Obscura copies the reincarnation variant of this trope. But subverts it when you find that the wizard/saint (whose soul you allegedly inherited) is in fact.
 * Zero struggles with various levels of amnesia in the Mega Man X series. He keeps getting flashbacks of his creator, Dr. Wily, but remembers nothing else from before Sigma captured him. In the Zero series, he's even lost his memory of the X series—everyone tells him that he's a "legendary Reploid" and he just has to take their word for it.
 * from Lunar: The Silver Star (and its Updated Rerelease) is revealed to be the human incarnation of the Goddess Althena. not the main character, though. One of the main characters, but not the main character.
 * But she is arguably the most important character.
 * In Persona 3, the main character discovers that he is
 * In Persona 4, the main character is revealed to be
 * Devil Survivor,
 * Castlevania: Aria of Sorrow had a plot twist:
 * Then the direct sequel, Dawn of Sorrow, states this early on in the game, spoiling it for anyone who played it before Aria of Sorrow.
 * Kratos from God of War is revealed to be . Of course, it's not like this was uncommon in Greek mythology.
 * In Soul Nomad and The World Eaters the main character is revealed to be
 * The eponymous character in Lufia is . This also applies to in Lufia: The Legend Returns.
 * Subverted in The Legend of Zelda: The Wind Waker. Unlike all of the other games in the series, this game's particular Link is not the reincarnation of the Hero of Time, and as a result he is required to go and find the Triforce of Courage by himself to be deemed worthy to hold the Master Sword. Played straight with the reveal that.
 * In Knights in The Nightmare, the Wisp is the soul of the late king, as well as the Arbitrator. This is absolutely no secret to the player, as Maria and Meria inform you of this very early on. The question of "Yes, but what does an Arbitrator do?" isn't explored until much later on. It leads to a bit of dramatic irony, as the player can piece things together a lot easier than the Wisp itself, which seems rather reluctant to remember much.
 * Also the case with Garlot in Blaze Union--he is the first pureblooded descendant of the demon god Brongaa to be born in centuries. He doesn't know this because his mother—who feared that his powers might be too strong and would lead him to becoming used by others... and just sort of feared his power—sealed said powers and Mind Raped him into believing himself to be human when he was a toddler. This even caused him to forget his real name, Gulcasa. His mother didn't think that the seal was strong enough, so she left the family to go find out how to make a stronger one... and then It Got Worse for Garlot. Much, much worse. Whether or not he realizes his true identity varies by route.
 * Three times in Gloria Union - Also,  Whether or not any of these facts are discovered may or may not depend on route.
 * Arx Fatalis featured, as I recall, partway through the game, the revelation that the main character was in fact a form of supernatural manhunter, sent specifically in order to prevent a particular deity from manifesting on the material world in which the game is set. The amnesia in this case, I believe, was said to be normal, usually being dealt with by virtue of a contact on the destination world. Alas, in this case, said contact ended up dead, and our protagonist started off in a goblin jail...
 * Zidane of Final Fantasy IX is told late in the game that . This, combined with, triggers a very uncharacteristic Heroic BSOD. Of course, Garland wasn't counting on his True Companions.
 * The Tales (series) loves these. The main character will inevitably be revealed to be special in some way:
 * Cless from Tales of Phantasia is the son of the warrior who sealed the Big Bad a generation ago (this is a minor example, as it is revealed fairly early).
 * Lloyd from Tales of Symphonia is
 * And in the sequel
 * In Tales of the Abyss, Luke turns out to be the Chosen One.
 * In Metal Gear Solid, Solid Snake discovers he's  rather than an ordinary but talented soldier like we'd initially assumed.
 * In Pokémon Mystery Dungeon: Red/Blue Rescue Team, the hero eventually discovers . Notably,.
 * One-upped in Explorers of Time/Darkness/Sky, where it turns out.
 * A large driving point behind Xion, and to a lesser extent, Roxas, in Kingdom Hearts 358/2 Days. Unlike the other members of Organization XIII, they have no memories of their previous lives and wield the Keyblade, the only thing able to accomplish the Organization's goal..
 * Parodied in Dragon Knights III (Xentar Knights in Western release.) Desmond's legendary prowess is revealed to be his birthright as the son of the God and Goddess of Good. To ensure he'd be prepared for his destined battle with the son of the Gods of Evil, they bestowed on him effeminate beauty and irresistibility to women, so he would always be faced with trouble. To disguise his nature as a god, they cursed him with foul body odor and laughable genitals. They did not offer to revoke those curses after the battle.
 * Radiant Historia: Stocke is This is why he was given the power of the White Chronicle at the beginning of the game.
 * E.Y.E.: Divine Cybermancy: If you manage to get to the end of the hidden labyrinth,
 * Inverted in Ghost Trick. The information Sissel gathered on himself is being contradicted and discredited bit by bit, until he (and the player) thinks he knows nothing. Turns out he's wrong. He does know something about himself that's so basic that it's not worth noting ... then that gets overturned in an amazingly decisive way! It's that kind of game.
 * Dark Souls, according to both Darkstalker Kaathe and Word of God, humanity in it's entirety is descended from the Furtive Pygmy, and as a result inherited a piece of the titular Dark Soul through him. This means every human is a descendant of a god and has access to his powers like the Dark Hand.
