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 don't 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.

Characters
Several characters were planned to appear on the playable roster:
 * Rock Lee and Sasuke Uchiha from the Naruto series.
 * While Rock Lee's Final Smash was never revealed (leaving it open to speculation from fans), Sasuke's Final Smash was planned to be his Cursed Seal form, a Final Form meant to enhance his moveset with new attacks.
 * 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.
 * Renji Abarai from the Bleach series.
 * Renji's Final Smash was planned to be Bankai: Hihiō Zabimaru, where he would turn his Zanpakutō Zabimaru into its Bankai form, then send it into the ground in its Shikai state and having numerous blades sprout from the ground.
 * Fan characters Blade and Blue, along with newcomers Azrael, Robo Ninja, and Spikeman.
