Erase Data, previously known as Backup Clear in Super Smash Bros., is an option in the first three installments of the Super Smash Bros.. It allows the player to erase specific data in the game, such as high scores, trophies, and characters. In all three appearances, the option to erase singular categories of data is available, alongside an "Erase All" ("ALL Data Clear" in Smash 64) option.
Once the player erases data, there is no way to recover it. As such, Super Smash Bros. Melee advises players to save a copy of game data onto a separate memory card before erasing data. However, this is not possible in Smash 64 nor Super Smash Bros. Brawl. The game data is directly saved into the game cartridge for Smash 64 and the game data cannot be copied from one Wii to another (nor to an SD Card) in Brawl.
Neither version of Super Smash Bros. 4 nor Super Smash Bros. Ultimate has an "Erase Data" menu, making it impossible to selectively erase any specific data. In Super Smash Bros. for Nintendo 3DS, players can erase all data at once by holding A, B, X, and Y on startup and selecting "Yes" three times when prompted (just like in Brawl for "Erase All"). In Super Smash Bros. for Wii U, the only way to erase data is to delete the entirety of the game's data file in "Data Management" under the Wii U system's "System Settings." In Super Smash Bros. Ultimate (similar to the Wii U and Wii U version of Super Smash Bros. 4) the only way to erase data is to delete the entirety of the game's data file, which is found in the "Manage Save Data/Screenshots and Videos" section of "Data Management" under the Nintendo Switch system's "System Settings".
