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 can be five characters long, whereas Melee allows only four characters. In Super Smash Bros. for Wii U, names can have up to ten characters. A name will have its own records for things such as KO's, SD's, damage taken, pratfalls, etc., which can be seen in the Records menu. 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 and can then be transferred to another Wii console.
In rare cases, names may affect gameplay. For example, in Melee, name tags remain visible even if they are pointing to an invisible character, making it easier to punish teleportation special moves such as Farore's Wind and Vanish.
The Name Entry is a menu where names are entered and managed. In Melee, it is found in the VS. Mode menu, while it is found under "Options" in Brawl; in Smash for Wii U, it can be found in both places. New names can also be typed in at the Character Select screen, although in Melee, it will shift screens to a name entry screen; in Brawl and Smash for Wii U, a new name may be typed in directly, although controls cannot be set this way.
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 allows the same possibilities. The NTSC version of Brawl allows uppercase Latin letters, punctuation, numbers and Japanese characters.
There is also an option to have the game enter a random name. Most of the random names that can appear are names of existing Nintendo characters.
The Name Entry will refuse to set names such as "CPU" and "P1", likely due to them being tags for players without names. However, variations with lowercase letters, such as "Cpu" and "p1", can be set.
