Names are a feature in Super Smash Bros. Melee, Super Smash Bros. Brawl, and Super Smash Bros. for Wii U. It allows a player to input a short string of characters as a name to use in gameplay, where it will "float" above the character. In Brawl, the string could be five characters long, whereas Melee allowed a length of four. Names can also be used to store data and records under them. A name will have the records for things such as KO's, SD's, damage taken, pratfalls, etc., which can be seen in the Records pages of the games. Names can also be used to set Rumble on a controller and save a control preference for a player that uses different controls to the default setting. This effectively makes techniques like B-Sticking and T-Sticking available to use. In Brawl names can be transferred to the Wii Remote which can then be transferred to another Wii console.
Melee features "random names" that can appear when entering the name entry menu. Most of these names are of existing Nintendo characters. Strangely, though, one of the random names in Melee is "Ike", who did not exist at the time, but was a playable character in Brawl.
In the European version of Brawl, Latin uppercase and lowercase characters, including diacritics, could be used, as well as punctuation and numbers. The PAL version of Melee held the same possibilities. The NTSC version of Brawl allows uppercase Latin letters, punctuation, numbers and Japanese characters.
The Name Entry is a console where names are put in and managed. In Melee, it was found in the VS. Mode menu, wheras it's found under "Options" in Brawl. In both games, however, new names can be typed in at the Character Select screen, although in Melee, it will shift screens to a name entry screen; in Brawl, a new name may be typed in directly.
In Brawl, this section is only called "Names".
In both Melee and Brawl, the Name Entry will refuse to set names such as "CPU" and "P1", likely due to them being tags of players without names. However, variations with lowercase letters, such as "Cpu" and "p1", can be set.
