List of Super Smash Bros. pre-release and unused content

This is a list of beta elements for the game Super Smash Bros.

Early iteration
Super Smash Bros. was initially developed by Masahiro Sakurai and Satoru Iwata in their downtime, in a form titled 格闘ゲーム竜王 (Kakuto-Gēmu Ryūō, or Dragon King: The Fighting Game), which lacked Nintendo characters. Iwata, however, felt that the game could not provide the proper atmosphere on a home console without Nintendo characters, and they were soon added and the game was redesigned.

Early builds
Princess Peach, Bowser, King Dedede, Pit, Wario and Mewtwo were all supposed to appear in the game as playable characters but were all scrapped. Peach and Bowser were cut due to the N64's technical limitations, and King Dedede, Pit, Wario and Mewtwo were cut due to time, although Peach and Bowser then become playable in Melee and Brawl, while Mewtwo became playable in Melee and King Dedede, Pit and Wario became playable in Brawl. In the character select, the question mark boxes were originally supposed to be colored (in the final version they're all black). Saffron City initially had a pink and purple color scheme on the rooftop. Final Smashes/Smash Balls were originally planned for this game, but cut for unknown reasons. Recordings of the character's voices during their Final Smash made for the original game of the series are still used in Super Smash Bros. Brawl unedited. . Peach's Castle initially lacked the sign, bridge and sliding stone block present in the final version.

Unused data
In the final game, two early Kirby stages are only playable with a GameShark. The stages have strange elements, such as invisible barriers. A working Dream Land stage can be viewed in the "How to Play" tutorial, which itself can be seen by waiting on the title screen. There are two unused Announcer voices: "Are You Ready?" and "Final Stage!".
