The Super Smash Bros. (Japanese: 大乱闘スマッシュブラザーズ) series, sometimes abbreviated as Sumabura (Japanese: スマブラ) in Japan, is a series of fighting games published by Nintendo. It features mainly Nintendo characters (with some third party characters as of third and fourth entries in the series) and the main objective of the game is to deal damage (measured in %) and knock characters off the screen. The higher % value a character has, the more easier it is to knock them off the screen.
The original idea for the game originated from a prototype called "Dragon King: The Fighting Game" (Japanese: 格闘ゲーム竜王), which Satoru Iwata and Masahiro Sakurai worked on together. Masahiro Sakurai handled the planning, specs, design, modeling and movement and Satoru Iwata handling the programming. [1][2] When this game was in development, there were originally no Nintendo characters until Nintendo approved.
