Heart
Hearts are a form of currency in Angel Land and are accepted in every Store. Nearly every enemy drops one when defeated, and special care must be taken to avoid leaving the resulting Heart out of Pit's reach. Exposed Hearts vanish after a few seconds. They come in three size varieties:
Heart: This grants 1 Heart.
Half Heart: Bestows 5 Hearts.
Big Heart: Worth 10 Hearts.
Appearances
Kid Icarus
In the original Kid Icarus, all enemies (excluding bosses and two other standard foes) would automatically drop these once defeated. The size of the heart depends on what enemy was defeated. These could be traded in for goods at any store, and a very large amount of hearts could be traded at the black market for any stolen weapons.
Kid Icarus: Of Myths and Monsters
The monetary heart system hasn't changed since the previous adventure, but enemies may instead drop Hammers and goblets of life water when defeated.
Kid Icarus: Uprising
As in the previous adventures, hearts will be dropped by all enemies when defeated and will give Pit points for collecting them. He can use these to buy things just like in the earlier games. Small hearts will automatically move towards Pit without him having collect them individually. Big hearts (now with silver or gold frames), on the other hand, must be collected manually like in the original games. Also this time around, Pit can offer hearts to Palutena, but whether or not if she gives the player something in return is currently not known.
Trivia
- Hearts bear a striking visual resemblance to Heart Containers from the Legend of Zelda series.
