|“What you call "mud" is concentrated evil. A Dark Matter that with one drop could make a man's heart turn as black as night.”|
|— The Overlord to Garmadon|
Dark Matter (also called Concentrated Evil) is a sinister muddy matter known for turning someone evil.
Dark Matter is a violet material commonly mistaken for mud mined from Digger's Deep. In its natural state, it has light purple dots and a visible glow—when refined for weapons use, it becomes almost black in coloration. It is usually handled in trays or the Garmatron. Dark Matter is used in a shell, and it bears resemblance to regular stone.
- Dark Matter was weaponized for the ultimate weapon to make Ninjago in Garmadon's image.
