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

This is a list of pre-release and unused content 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 and it was originally planned for the SNES. 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
Several more characters were planned to be in the game (Bowser, King Dedede and Mewtwo being the only characters to be specifically mentioned ), but were cut due to time constraints. In the character select, the question mark boxes were originally supposed to be in color/colour (in the final version, they are all black, and show the character silhouette). Saffron City initially had a pink and purple color scheme on the rooftop. Final Smashes were originally planned for this game, but were cut due to hardware limitations. However, half of the characters in the game have multiple unused Final Smash voice clips. 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 four unused Announcer voices: "Bonus Stage!", "Draw Game!", "Are You Ready?" and "Final Stage!". It is also worth noting that "Bonus Stage!" is in the Sound Test as number 198 in the "VOICE" section.

Aside from unused Announcer voices, there are also unused character voice clips in the game. Some of these voice clips are used in the second game.
