Revival platform

A revival platform is the mean whom a character is brought back to the stage once they have been KO'd in Super Smash Flash 2 and, as such, is a feature absent from Super Smash Flash. All revival platforms look similar, usually a circular platform with a white tinge to it and with different sizes regarding the character. Often it would be lit-up. Once a character comes back on the battlefield, the character will be immune to any attack for a few seconds. Also, the color of the platform changes, matching the main color of the palette.

Origin
The revival platform originates from the game Mario Bros.. When Mario or Luigi loses a life, the plumber re-spawns on a small platform, accompanied by a short melody. While on the platform, the plumber is invincible. The melody that plays when Mario or Luigi re-spawns is not included in the Super Smash Bros. games or Super Smash Flash games.
