Fan Casting Secret Character in Sort by Tropes

A secret character is a character where the player has to complete some sort of specific action in order to challenge and/or unlock them. Like any other form of Unlockable Content, doing this is not required to finish the game. If the game's a Role-Playing Game, this character can be recruited to your Player Party, sometimes through extremely convoluted means, sometimes as New Game Plus reward. In this case, the fact that they can join you can make them a Walking Spoiler. 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 of versus matches completed or a set amount of gameplay time for those who don't want to play the story mode.
