Dark Matter is the main antagonist of Pokémon Super Mystery Dungeon. Dark Matter is an entity born out of the negative feelings of all the Pokémon in the world. By absorbing a Pokémon's life energy, it has the ability to turn them to stone. When a Pokémon's body is turned to stone, its spirit is sent to the Voidlands, a dark realm swarming with Void Shadows, Dark Matter's minions capable of taking on the form of Pokémon. Dark Matter is also able to possess Pokémon that have even the smallest amount of darkness in their hearts. Using its mind-controlled slaves, Dark Matter turns Pokémon to stone to absorb their energy and grow stronger. Its ultimate goal is to "return the world to the void", namely to cause its spinning to stop and make it be consumed by the sun. It attempts to accomplish this by absorbing energy from the Tree of Life, the source of all the life in the world.
