Supposedly he was a Lin Kuei ninja who abandoned the clan and joined the Black Dragon.

He had control of the ground and could create tremors to attack people.

I read that Tremor was to be put in MKT, but eventually pulled out. However, in early versions of the game his bio would appear as a glitch. And below you can read Rain's false Bio that originally belonged to Tremor:

Rain is an assassin working freelance. He was once a member of the Lin Kuei along with Sub-Zero, but left the clan under mysterious circumstances. Years later, Rain is found working for Shao Kahn as an assassin in the Outworld. Born a human, he finds himself questioning his loyalty towards Kahn after watching the invasion of Earth.

So most probably, Tremor indeed was a Lin Kuei member at first. But in MK:SF he belonged to Black Dragon and was a portal guard boss at the end of 4th level. His attacks were mainly earth tremors.

Here is his MKSF concept art:






and here's an in-game pic


I actually like his potential, earthquake abilities haven't really been explored, and would be good in the 3D games.

umm link for that image please?
