The Pure Hearts are powerful artifacts created by the Tribe of Ancients in Super Paper Mario. All eight Pure Hearts are pieces of the Purity Heart, and they were created by the Ancients using the power of love, which was believed to be the only force powerful enough to save all worlds from destruction.
The Pure Hearts were created as part of the prophecies detailed in the Light Prognosticus, which state that four Heroes of Light must gather all eight of them in order to counteract the Chaos Heart and defeat the one who wields it. When placed in a Heart Pillar, each Pure Heart leads to a dimension where the next one is located, through a series of doors at the top of Flipside Tower. The Pure Hearts are eight pieces of the whole Purity Heart, which was divided into the Pure Hearts by the Ancients so it could be hidden across different dimensions.
The first Pure Heart is held by a descendant of the Ancients named Merlon, who gives it to Mario, the first of the four heroes, with the task of traveling through dimensions in order to gather the other seven and stop Count Bleck from destroying all worlds using The Void. During his journey, Mario eventually comes to reunite with Princess Peach, Bowser, and Luigi, all of whom are proven to be the remaining three Heroes of Light, and together, the four of them manage to collect all eight Pure Hearts and travel to Castle Bleck to battle against Count Bleck, the holder of the Chaos Heart.
Despite the immense power of the Pure Hearts, they are not indestructible, and can be weakened--for example, the Violet Pure Heart was turned to stone upon being consumed by The Void along with the rest of Sammer's Kingdom. It was revitalized by Queen Jaydes of The Underwhere, using her power over life and death. In addition, the power of the Pure Hearts is depleted after they are used to break through the Chaos Heart's protection over Count Bleck, though they are all revitalized by Bleck's minions.
At the end of the game, Dimentio, having stolen the Chaos Heart for himself, uses the last of his power to sustain the Chaos Heart long enough to ensure the destruction of every world. In their final moments, Count Bleck and Tippi--now revealed to be long-lost lovers Lord Blumiere and Lady Timpani--reaffirm their love for each other, sacrificing themselves in order to save all worlds; their vows manage to unite the Pure Hearts into the whole Purity Heart, destroying the Chaos Heart and reversing the prophecy of destruction.
The eight Pure Hearts, as well as their locations and keepers, are listed below.
