List of unused and removed content of Super Smash Flash 2

Any unused or removed content refers to certain content from video games that was removed or altered in some way before a product reaches completion. This can be affected by certain factors, including changed ideas, new mechanics implemented that do not work with the old model, or simply because it was deemed unnecessary. The following list consists of those that were originally planned to be in Super Smash Flash 2, as well as any elements shown in a Super Smash Flash 2 Demo that were removed.

 * Rock Lee and Sasuke Uchiha from the Naruto series.

 * Vegeta from the Dragon Ball series.
 * Vegeta's Final Smash was planned to be his Super Saiyan form (like Goku's), a Final Form which would enhance his moveset with new attacks.
