A Heartless is a fictional enemy in the video game Kingdom Hearts. The Heartless are emotionless and empty creatures that devour worlds and embody everything that is darkness. There are two different kinds of heartless:Pureblood Heartless and Emblem Heartless.Pureblood Heartless are the most common, but have a small range of species. Common pureblood heartless include Shadows, Neoshadows and certain bosses like Darkside. Pureblood Heartless do not release hearts, unlike the Emblem Heartless. When a Heartless is destroyed, it's heart gathers with other hearts into an entity known as Kingdom Hearts, which is often used by the antagonists of the game.Emblem Heartless are a sort of artificial Heartless that have a symbol of a heart located on their body. They have a wide variety of species. The Emblem Heartless must be destroyed by the Keyblade, otherwise the hearts they release will gather back into Heartless again.
