The revival platform is a special platform in all Super Smash Bros. games that appears after a player has been KO'd. Provided the player is not out of stocks, they will respawn on a platform floating above the center of the stage. The platform disappears as soon as the player moves or attacks. If the player does not act, the platform will disappear by itself after 5 seconds; in Super Smash Bros. 4, this time limit is represented by a section of the platform that gradually changes color from yellow to red. The platform cannot be boarded by any other character. If multiple players are KO'd at or nearly at the same time, then more than one platform can be on the screen at once, one for each KO'd player, appearing next to each other. If 5 or more characters are KO'd around the same time, some revival platforms will be above others.
The revived character is invincible the entire time they are on the platform. This may be used to avoid temporary dangers such as an opponent using a Final Smash. In addition, many players utilize the invincibility to plan out their strategy and gather their thoughts. After dropping down from the platform, the character has a further period of invincibility to aid their descent. In Super Smash Bros. Ultimate, the period of invincibility after leaving the platform is decreased proportionally to the amount of time the player spent waiting on the platform, making the total amount of invincibility roughly the same no matter when the player chooses to drop down.
CPUs generally exit the revival platform immediately; however, high-level CPUs tend to wait on the platform for as long as possible during a transformation Final Smash, or when a player on screen is using a powerful item, such as a Golden Hammer.
The animation for characters being revived has not changed much over the games. After a KO, the character will simply descend from the sky on the revival platform. The original game has a slightly different animation; upon appearing on the platform, characters will be lying down, and will then get up as the platform descends.
In the original Super Smash Bros., a character gets the Mystic bonus for being on a revival platform when his/her opponent is KO'd. In Melee, the player gets the Angelic bonus when the match ends this way.
The revival platform originates from the game Mario Bros. When Mario or Luigi loses a life, the plumber respawns 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 respawns is not included in the Smash Bros. games.
