Secret Character

"HERE COMES A NEW CHALLENGER!"

- Street Fighter

A character that the casual player may never see. Not due to some strange invisibility, or even things that he should know but are All There in the Manual. Like any other form of Unlockable Content, getting the Secret Character is not required to finish the game.

If the game's a Role Playing Game, this character can be recruited to your Ragtag Bunch of Misfits, sometimes through extremely convoluted means, sometimes as New Game+ reward.

In a Fighting Game, uncovering the character may be as simple as holding down a button while you select a certain fighter, or you may have to beat the game on the hardest setting, without using any continues. In many fighting games, there is also a secondary path to getting characters that usually entails a set number (usually in the hundreds) of versus matches completed or a set amount of gameplay time if you really don't want to play story mode.

Some Secret Characters can be Lost Forever depending on the means used to unlock or acquire them.

Action Adventure

 * Since Symphony of the Night, Castlevania has featured unlockable characters, usually the secondary characters. Dawn of Sorrow 's Julius Mode, besides being a tribute to Castlevania 3, is also a rare example of a Bad End Plus: the reason you're playing as Julius is to

Action Game

 * After beating Killer 7 once on any difficulty, you can go back and re-play the game in killer8 mode, which gives you access to the previously unavailable Young Harman character, whose huge amount of health and tommy-gun make him almost a Game Breaker. You'll need him though, since the only difficulty level available for killer8 mode is Bloodbath, where enemies take obtuse amounts of damage, give almost no blood at all, and have invisible weak points.

Fighting Game

 * Most famous Fighting Game example: Akuma/Gouki in Super Street Fighter II Turbo, who began life as an April Fool's day joke by EGM. Now subject to Wolverine Publicity, as he shows up in games which aren't associated with Street Fighter, like Cyberbots, where he appears as a giant robot version of himself.
 * Street Fighter Alpha also had Akuma, but Joke Character Dan Hibiki made his debut as a secret character in the first Alpha game. Alpha 2 featured Shin Akuma and Evil Ryu.
 * SN Kvs Capcom: SVC Chaos had a buttload of secret characters. Some of them were the ones you woudl expect like Dan or Geese, while others included Zero and Demitri. It also featured an evil version of Ken, called Violent Ken, based off of his possessed self from the Street Fighter 2 movie.
 * Battle Arena Toshinden: In order to play as Gaia and Sho, the two bosses, you had to enter two codes on the title screen before the options showed up, then select either Eiji or Kayin while holding certain down certain buttons on the D-pad
 * Most of the modern WWE games have former WWE talent as hidden "legends".
 * Recent WWE games can be hacked to unlock WWE management like Vince Mcmahon, Jim Ross, Michael Cole, Lillian Garcia, Mike Chioda and Nick Patrick.
 * Dissidia Final Fantasy: Shantotto and Gabranth join the heroes and villains (respectively) once their story lines are cleared, adding them to the PP catalog to be purchased.
 * This is the case for Prishe and Gilgamesh, and  in the sequel. Shantotto and Gabranth must still be purchased, but unlike the others the ability to purchase them is from the start.
 * A tradition in the Super Smash Bros series. Typically, you first unlock Jigglypuff by beating single-player mode once, and then the requirements get tougher. Each time you meet the requirements, you will fight that character with whichever one you were playing as at the time, and if you win you will unlock the character. Other typical requirements include beating the game without continues, with a specific character, or completing certain side events. Each game would also give you the characters if you logged a certain amount of multiplayer hours. In Brawl, there are three ways to unlock each character: getting them to join you in Adventure Mode, playing a certain number of Vs. matches, or by doing other events. Also, that version mixed it up by making Jigglypuff one of the last characters you unlock.
 * Mewtwo in particular took the Guide Dang It to the extreme, you have to play over 20 player-hours (that is, 20 hours divided by the number of people playing) or fight around 700 matches.
 * Sheik and Zero Suit Samus are technically "secret" in Melee and Brawl respectively because you cannot play as them right from the start without holding a button.
 * Tekken's "Devil Kazuya" was unlocked by leaving the game on for 30 hours. Alternatively, one could get a perfect score in the game of Galaga that replaced a standard Loading Screen at the very beginning of the game.
 * In the Killer Instinct games, the Big Bad could be played as by entering certain button combinations as the fights loaded.
 * In the Fighting Game One Must Fall, it was possible, through a series of button sequences, to play as both the end boss, and use his towering robot (not normally available in the story mode). There were also a lot of secret characters you couldn't play as, but could access for special fights, both in story mode and tournament play--"unranked challengers". In tournament mode, some of these unranked challengers would appear in other tournaments, some were the only appearance of a story mode character in the tournaments, some were references to other Epic Games franchises, and some were just unique characters who only popped out surprise you.
 * Guilty Gear is outright vicious about unlocking characters. In XX, to unlock Robo-Ky, Kliff, and Justice, you must do one of the following: complete forty of the game's fifty (insanely hard) missions; complete all the story paths (some of which are Guide Dang It, some of which are outright painful, and some of which are both) for all characters; or complete over 200 levels of Survival Mode (which amounts to seventy or so battles - including twenty much harder "Daredevils"). Or just leave the game running for several days. Then, there are the laternate movesets for most of the characters, which are practically characters unto themselves...
 * Lightning Legend Daigo no Daibouken has four unlockable characters. Defeat Means Playable is the way to get them; it's not a problem for two of them, who are, but the other two are   requiring near-completion of the game and no continues in a playthrough in addition.
 * Toraichi and Toraji in Nekketsu Kakutou Densetsu.

Platform Game

 * There are a few secret characters in the Sonic the Hedgehog series. The Super Mode versions might count, but there's also Metal Sonic in Sonic Adventure DX who is available after getting all 130 emblems (though he's only available in trial mode and can't do Sky Chase), as well as Amy in Sonic Advance 2 after beating the game with all the Chaos Emeralds with the previous 4 characters.
 * The first Viewtiful Joe game lets you play as and even  ( who is unfortunately, only unlockable in the PS 2 version of the game) by beating the game's multiple difficulty levels.
 * Super Meat Boy has a whole host of entirely optional secret characters from other various indie games, including Commander Video, Naija, a headcrab, The Kid, Captain Viridian, the alien hominid...
 * Luigi has become this in many of the recent platform games, usually because his abilities tend to overshadow Mario's gameplay-wise.

Puzzle Game

 * Super Puzzle Fighter II Turbo Scrolling off to the side on the character select screen revealed a few secret characters, including Dan. Also, holding down a button while selecting certain characters turned them into others.
 * Shift 3 lets you unlock Fancy Pants from Fancy Pants Adventures.
 * Wrecking Crew '98 had four original secret characters: Onigiri, Onnanoko, Oyaji and Dogu. As with the normal opponents, Defeat Means Playable, but they might not even be seen on a normal playthrough.

Real Time Strategy

 * In War Craft 3, you can recruit a Hydralisk unit from Starcraft for one mission. It was only one mission, but he was hidden quite a ways away.
 * Likewise, in the expansion pack it was possible to receive an extra hero unit for one mission providing you first triggered a secret mission in the preceding mission and then completed said secret mission.

Racing Game

 * In racing games, you often have secret vehicles rather than secret characters. Though some games like the Mario Kart series are character driven enough to qualify.

Rhythm Game

 * The Cheer Girls and the Divas in Ouendan and Elite Beat Agents aren't particularly secret; they have their own bios in the manuals and everything, they're just really, really hard to unlock.
 * Not terribly. You get them by beating hard mode, which unlocks Harder Than Hard mode. in EBA< beating that allows you to
 * Space Channel 5 Part 2 somewhat does this. By completing Reports with 100% and by doing other things, you can play as other characters in the game, including the Big Bad.

Roguelike

 * Certain demon-lords in Nethack have no "fixed" lair and only turn up when/if summoned. It is entirely possible to finish the game and never meet them. (And in the case of Demogorgon, this is mostly considered a good thing...)

Role Playing Game

 * Saga Frontier: Sei required you to finish a sidequest in an optional dungeon; Time Lord and Kylin required you to get two gifts of magic first to even access the quest to recruit them (or buy their magic); Suzaku required you to defeat an obscure miniboss who randomly appeared if you fight a certain monster in the previous screen; and Rei was another Guide Dang It character available only in Asellus' quest and was Lost Forever if you forgot to do something or did something you shouldn't have done at the start of said quest.
 * Wild Arms: In the second game, you recruit Marivel in a completely optional dungeon. Alter Code, the remake of the first game lets you recruit Zed after a Bonus Boss fight and after you give him an item acquired in the last dungeon.
 * Suikoden II lets you recruit the overpowered main character of the first game as a non-Star. It required a last dungeon save file from the first Suikoden and a Side Quest.
 * Suikoden Tactics did something similar for the main character of Suikoden IV. Also, considering the Suikoden games always have around 100 Optional Party Members, (There's always 108 characters, but some are automatic, permanent members) there's often a boatload of difficult to get ones.
 * Planescape Torment: You can get a special character, the Rogue Modron Nordom, only by exploring a bizarre pocket dimension where the inhabitants are trying to understand the concepts of dungeon-delving. The result is a randomly generated maze, creating by opening and shutting various doors between the myriad chambers, and Nordom can only be found in a specific chamber. To even get to the pocket plane, you buy a specific item (the "Metallic Cube" - a poseable Modron figurine) from Vrichika's Curiosity Shoppe. Then, after talking to the Modrons in the Brothel of Slaking Intellectual Lusts to discover that it is a portal, you have to figure out on your own the specific pattern you need to alter the figure's limbs into to activate it (extend left wing, extend right wing, rotate right arm). Once there, you first have to fight your way through a randomly generated maze (fortunately set on "Easy" difficulty) to find the control room. Then, from there, you have to set the maze to "Hard" and then try and find the room where Nordom is waiting. Did we mention that, on this difficulty, the maze is filled with powerful enemy constructs, which can make this a Bonus Level of Hell if the party doesn't time Level Grinding on either the Easy or Medium settings? And that, as this maze is randomly generated, you may need to reset it over and over before Nordom's chamber becomes accessible?
 * However, all Torment PC's are unique and don't even stand out very much from the crowd given that unique characters are all over the place. As with many other such characters, Nordom is hinted at but not explicitly identified. Morte and Annah are the only characters you will definitely encounter. Second, Nordom is also always found in his dungeon on Hard if you look around. Third, let's not forget Vhailor, who is even more secretive: you have to walk past a certain portal into a room you couldn't get into before, and which doesn't obviously show up.
 * Breath of Fire II: Bleu/Deis. You must walk over a specific panel in a random desert with nothing else in it after reading a certain book. The book both unlocks the panel and tells you, if obtusely, which one it is.
 * The Final Fantasy series has a few:
 * Final Fantasy VI: Gogo the Mime was found in a small optional dungeon which you accessed by fighting an enemy that only appeared in one place, and letting it eat you instead of killing it.
 * Also from Final Fantasy VI was Umaro who can be found by jumping off a cliff where the Esper Tritoch/Valigarmanda was and having Mog in your party.
 * Final Fantasy VII: Yuffie appeared as a random battle, and the player must select certain dialogue options to get her to join. The game was merciful, though, in that she would appear later until the player gets it right (justified as she stole from you each time you got the sequence wrong). Also Vincent, who involved solving puzzles in a haunted house. After finally finishing the puzzles, surprise! Boss Battle! Also made annoying in that the boss was very tough if you didn't know what you were doing, and there's still little indication on what you're supposed to do to actually recruit Vincent.
 * Not only did you need a strategy guide to find these two, but they were in the ding dong instruction manual! That's right, the two secret characters you could miss very easily? They're mentioned in the instrusions! And then there was Dirge of Cerberus...
 * Paper Mario the Thousand Year Door had Ms. Mowz, who makes several appearances as an NPC but won't join unless you do a certain side-quest.
 * Time Stalkers has Marion. Although not a secret by any stretch (she's listed in the manual with all the other characters), the method for getting her is convoluted and relies entirely on luck--you have to find her as a randomly generated item.
 * In the Pokémon games, there are a few secret characters in every game. First generation had Mew, second generation had Celebi, third generation had Jirachi and Deoxys and fourth generation had Darkrai, Shaymin and Arceus.
 * Generation V adds Victini, Keldeo, Meloetta, and Genesect.
 * To any Americans playing Gen. II: No Celebi, sorry. The related event series was removed for the English version.
 * Natsume in .hack//G.U. Vol. 3: Redemption. She only appears if you've defeated all the Chaotic Player-killers, and even then, you can't actually get her in the party until after you beat the final boss. Tabby from Roots is similar, as you find her on the 50th floor of the game's Bonus Dungeon.
 * With high enough Paragon/Renegade skill in Mass Effect 2, it's possible to.
 * in Shin Megami Tensei Nocturne. In Hell's Maze, you can encounter two souls; one that's red and another that's green . Talking to both of them causes a corpse to show up in Zoshigaya Cemetery, which is holding the Afterlife Bell. Bring the Bell to the two souls and ring it to bring them Back From the Dead as their former selves. That alone won't unlock them, however; you still need to fuse a pair of demons to get them. Dante and Black Frost also count, but they join you instantly regardless of your level.
 * Speaking of Megaten, from Persona we have Reiji, who is infamous for this. From Persona 2, we have the Custom Personae, which can be unlocked by certain dialogue choices, and Durga, which needs a certain choice as well. Also, from Eternal Punishment, the Ancestral Personae and Lugh.
 * On the Dragon Age wiki, "Secret Character" is the spoiler-shielding codeword for... the secret character of Dragon Age Origins.
 * Phantasy Star Portable 2 Infinity lets you at random find a KFC in dungeons... and recruit Colonel Sanders as a party member.
 * Many of the Legendaries in Pokemon Mystery Dungeon: Explorers of Time/Darkness/Sky. They don't appear at all unless you have either the Secret Slab or the Enigma Part, and from there, you'd need a strategy guide to figure out where exactly they appear.
 * The Hellfire Expansion Pack for the original Diablo came with two secret, "unlockable" characters: the Bard and Barbarian. The Barbarian has since reappeared in the sequels.

Shoot'Em Up

 * Star Fox Assault 's Multiplayer mode lets you play as the core Star Fox team, but Wolf O' Donnell can be unlocked. He has the same total stats as Fox, but with three maxed out skills (a maxed out speed in particular that lets him run around all the other characters), he is considered by some to be a Game Breaker.
 * Raiden Fighters Jet has the Slave and Fairy planes, unlockable by holding the bomb button when pressing Start at the title screen. The Slave will replace whichever plane you select, inheriting its movement speed and bomb; the Miclus is replaced by the Fairy instead.
 * In Phantasmagoria of Flower View you can unlock Merlin and Lunasa Prismrivers if you complete the Nintendo Hard Extra Mode with Komachi and Shikieiki. Given that this game is from Bullet Hell genre, many casual players won't even try this (it's like the story mode, but with number of bullets on Lunatic standards, both you and opponent having one hit point while she has the invincibility time for the beginning of the fight, and without any spare lives or continues).
 * In the iOS port of Daifukkatsu you can unlock  as a playable ship. And it is just as powerfull as it's boss counterpart.

Simulation Game

 * This is a fixture of the Tokimeki Memorial series. Each game contains at least two of them :
 * Tokimeki Memorial 1 : Miharu Tatebayashi and  ;
 * Tokimeki Memorial 2 : Maho Shirayuki, Maeka Kudanshita, and Sumire Nozaki ;
 * Tokimeki Memorial 3 : Kazumi Watarai and Hotaru Izumi
 * Tokimeki Memorial 4 : Rui Nanakawa, Haruna Mizuki, and
 * Tokimeki Memorial Girl's Side : Aoki Chiharu, Tendou Jin (for the DS Version 1st Love)
 * Tokimeki Memorial Girl's Side 2nd Kiss : Akagi Kazuyuki, Majima Tarou and Komori Taku (for the DS Version 2nd Season)
 * In Frozen Essence, not completing the requirements for any character's path unlocks 's path.

Sports Game

 * The Backyard Baseball series has secret characters ranging from Mr. Clanky to the announcers to freaking Babe Ruth.

Stealth Based Game

 * Metal Gear Solid: Portable Ops allowed you to unlock a whole bunch of characters (usually through a New Game+, with a code as an alternative). A couple are from the Alternate Continuity MetalGearAc!d, and are only unlocked if you have a save file from the Ac!d games (or, again, through using the right code).

Turn Based Strategy

 * Super Robot Wars: Many secret mechs in the Super Robot Wars series. The methods for getting them vary from the simple (kill X number of enemies with character Y, especially easy when character Y is a walking engine of death) to the Guide Dang It, (beating a certain enemy with a single character, not attacking a particular unit in a fight, or reassigning a character to an incredibly weak robot before a certain mission, or winning a Hopeless Boss Fight).
 * Due to the nature of the games, this may not be so much Guide Dang It as All There in the Manual.
 * And quite often, there will be two or more hidden mecha/weapons that cannot be gained in the same playthrough (ex: Hyperion Gundam and Tekkaman Rapier in W, which are achieved on different sides of the same route split), making One Hundred Percent Completion impossible.
 * Final Fantasy Tactics: Cloud. An incredibly long series of actions and optional maps before getting him, Guide Dang It.
 * The PSP port/upgrade of Final Fantasy Tactics, Final Fantasy Tactics: The War of Lions, included Cloud and all of FFT's unlockable characters, as well as Final Fantasy XII's Balthier (as a secret character) and Final Fantasy Tactics A2's Luso (met in the story).
 * Final Fantasy Tactics Advance: 4 characters offer to join your party if leaving with certain mission items, 4 others from completing certain missions.
 * Final Fantasy Tactics a 2 had Frimedla Lotice, gained from doing five separate quests. The game also had Vaan, Penelo, Al-Cid Margrace and Montblanc as optional party members.
 * Nippon Ichi games, such as Disgaea or La Pucelle, often allow you to unlock characters from their other games.
 * Shining Force was horrible with these, and it extended to the sequels.
 * The game Vantage Master by Falcom allowed you to play as characters from their other games, by answering the questions to get a specific class, then naming the character appropriately. For instance, becoming a knight and naming him "Adol" lets you play the knight from the Ys games, while naming the swordsman "Mail" gives you the title heroine from the game Popful Mail.
 * Fire Emblem: Path of Radiance has Stefan, who is very, very vaguely hinted at... and nowhere in the hint is it mentioned that you can only unlock him with two specific characters (neither of which are the main character, whom you use to recruit about 85% of the recruitable units). He's very much worthwhile, and would be even if he didn't come with the second best sword in the game, losing only to the Eleventh-Hour Superpower sword Ragnell (which only Ike can wield anyway).
 * Radiant Dawn is far worse. Stefan returns as even more of a Guide Dang It, especially as you only get your vague hint after he's Lost Forever. But even worse is the other Secret Character, . You have to go through several convoluted steps (hinted at nowhere in the game), one of which can be completely impossible if you were unaware of it several chapters beforehand (or even just had bad luck with the Random Number God). And if you finally do unlock him, guess what? You get him for one chapter. Namely the final boss battle. In which he comes with no weapon, meaning you just went through all those steps for practically nothing. Admittedly he does make a good white mage, but you should already have two of those (and possibly more).
 * If you're willing to give up Micaiah or  (if you got him) for magical attackers and give   Rexaura or Balberith, turns out, he's actually fast enough to double attack the Final Boss. For added fun, and possible symbolism, have him team up with Micaiah and perhaps Sanaki to bring   down. Nothing quite like happy
 * Advance Wars had Nell, and the sequel added Hachi. Both are gamebreakers.
