An unlockable character is a character in the Super Smash Flash series that is not available at the start of the game (unlike a starter character), but must be unlocked. Unique criteria must be met in order to unlock a certain character. In both Super Smash Flash and Super Smash Flash 2, typically, the player must accomplish a particular in-game feat and once complete, a message will display: "Warning! Challenger Approaching!" with a white question mark block over the black silhouette of the unlockable character.

By completing the in-game feat and defeating the opponent in a 1-stock match, the character becomes playable. In the original Super Smash Flash, this matches would always take place on Final Destination, but in Super Smash Flash 2, each character is fought on a different stage; their home stage.
