Pure Heart

The Pure Hearts are eight sacred hearts created by the Tribe of Ancients to save the world from the Chaos Heart. The Pure Hearts seem to be Super Paper Mario ' s the equivalent of Paper Mario ' s Star Spirits or Paper Mario: The Thousand-Year Door ' s Crystal Stars. Mario must find eight of these throughout his adventure to form the Purity Heart. The Pure Hearts are great treasures created by the Ancients. They supposedly hold great power. The source of power in these Pure Hearts are the power of love itself (parent, smitten, etc.). The Ancients researched love, believing it to be the universe's only salvation. They created the Pure Hearts as the embodiment of love. Hopefully, their combined brilliance would negate the destruction of the Chaos Heart, a feat which it ended up successfully performing.

Here are all eight locations of the Pure Hearts:
 * 1) Red: Kept by Merlon in Flipside and given to Mario when he begins his journey.
 * 2) Orange: Guarded by Fracktail deep within the Yold Ruins in Lineland. The Pure Heart was given to Mario by Merlumina.
 * 3) Yellow: Kept by Merlee in Gloam Valley.
 * 4) Green: Emerged in the Bitlands's Fort Francis after Mario rescues Tippi.
 * 5) Cyan: Hidden by the ancient Squirpians in the Whoa Zone somewhere in Outer Space.
 * 6) Blue: Kept by the Floro Sapiens in the Land of the Cragnons.
 * 7) Purple: Kept by King Sammer in Sammer's Kingdom.
 * 8) White: Personified as a Nimbi named Luvbi. Her foster parents are Grambi of the Overthere and Queen Jaydes of the Underwhere.

They have a defining trait: They are drawn by their own power toward those strong with love, likely due to their aforementioned love-powered creation. It is also interesting to note that Pure Hearts may be sapient, as the Luvbi character spoken of above actually managed to remember being a Pure Heart when her true being as a Pure Heart was revealed to her after a prolonged amount of time in which she thought she was born a Nimbi.
