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 match would always take place on Final Destination, but in Super Smash Flash 2, each character is fought on a different stage, being their home stage.

Yes.svg This section contains information for a confirmed feature that is not currently available.

The subject was confirmed by an official source, but is not present in the current version of the work bound to appear. Instead, it is meant for a future update. Any information is subject to change.

It has been confirmed that all characters added after the initial release of Beta 1.0 will be unlockable in the full version of SSF2. However, it should be noted that from Beta 1.2.0 onwards, all unlockable characters have been available without needing to be unlocked, in the same vein as starter characters. This is only temporary, as they will go back to being unlockable in a future update.
