Tremor was a forgettable palette swap ninja in the abbysmal Mortal Kombat: Special Forces game. He is equally hated by MK fans since not only is he just another palette swap ninja, but he also appeared in only one game, the aforementioned MK: Special Forces, which wasn't even a fighting game. I figured Tremor needed a bit of a makeover. I tried to make him look unique from the other MK ninjas, but the more I changed from the basic design, the less he looked like Tremor, so I had to go with the basic ninja motif.
