The Heart Container is a item from The Legend of Zelda series that appears in Super Smash Flash and its sequel, Super Smash Flash 2. In both games, the Heart Container will reduce 100% of damage of the player who picks it up. It used to be the best recovering item until the introduction of the E-Tank in SSF2, which completely reduces the damage of the player to 0%.
The Heart Container made its first appearance in The Legend of Zelda. At the beginning of The Legend of Zelda, Link starts off with three hearts. When Link can either buy a Heart Container from a merchanter or get one by beating a boss. Once he gets the Heart Container, it gives him one heart unit to his life meter; however, it was not used to replenish his health. In The Legend of Zelda: Link's Awakening, when Link finds a Heart Container, it gives him another heart and replenishes his health. This was also true in The Legend of Zelda: Ocarina of Time and The Legend of Zelda: Twilight Princess. In Super Smash Bros., the Heart Container reduces a character's damage to 0%, but in Super Smash Bros. Melee and Super Smash Bros. Brawl, it only recovers 100% max (although, the three Heart Containers found in All-Star mode reduce the character's damage to 0%). Nevertheless, the recovery is not instantaneous in any game and a player can still take damage whilst recovering. In Super Smash Bros. and Melee, the Heart Container appears as it does in The Legend of Zelda: Ocarina of Time. Its appearance changed in Brawl to its The Legend of Zelda: Twilight Princess appearance, similar to Link, Zelda, and Ganondorf. Being based on Melee, SSF uses Ocarina of Time's design; but SSF2, instead of Twilight Princess' design as Brawl did, uses the design from The Legend of Zelda: Skyward Sword. It, however, used to have the design of Twilight Princess, being redesigned thrice, before being changed to Skyward Sword's design.
