Chaos Heart

The Chaos Heart is a dark source of power from Super Paper Mario. As prophesised in the Dark Prognosticus, the Chaos Heart was unleashed by the marriage of a powerful king (Bowser) and a pure princess (Peach), and used to create an interdimensional rift known as The Void, which would engulf the universe.

The Chaos Heart was first controlled by Count Bleck, who wanted to destroy all worlds and create new ones out of inconsolable heartbreak due to the disappearence of his love, Lady Timpani. The Chaos Heart would soon be overridden and banished by the power of the Pure Hearts, closing The Void and saving the universe from destruction.
