Tremor is a brown garbed ninja and a member of the Black Dragon clan who first appeared in Mortal Kombat: Special Forces. He escaped from Special Forces custody during a prison break orchestrated by Kano, to whom he was blindly loyal. Kano assigned him to guard the portal to Outworld and kill any Special Forces agents that may have discovered his whereabouts. Tremor was defeated and killed by Major Jackson Briggs in their encounter.
