Erase Data, or Backup Clear in Super Smash Bros., is an option appearing in three of the four installments of the Super Smash Bros. games. 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. This is not possible in Smash 64 or Super Smash Bros. Brawl, as 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 or to an SD Card in Brawl.
Neither version of Super Smash Bros. 4 allows the player to erase any specific data in the game; in fact no "Erase Data" menu option exists in Super Smash Bros. 4. Both versions allow the player to erase only all of it. In Super Smash Bros. for Nintendo 3DS, players can erase all data by holding A, B, X, and Y on startup and selecting "Yes" three times when prompted (just like in Brawl for "Erase All"). However, in Super Smash Bros. for Wii U, this version of Super Smash Bros. 4 has no such built-in application. Players in Super Smash Bros. for Wii U instead can erase all data by erasing the game's data file in "Data Management" under their Wii U's "System Settings".
