Special Forces

The Special Forces was initially formed in the United States of America as the United States Special Forceswith the goal of stopping international crime gangs, in particular the Red Dragon and Black Dragon clans. By the time of Mortal Kombat: Armageddon, the organization has become the Earthrealm Special Forces; while it was still an anti-crime organization, its mandate had expanded to defending all of Earthrealm against outerdimensional invasions, such as by the Tekunin.

The game that includes the Special Forces as the main protagonists is Mortal Kombat: Special Forces for the Playstation. Kano and Jarek of the Black Dragon are the organization's main enemies. Jackson "Jax" Briggs,Sonya Blade, Cyrax, and Kenshi are the only playable character members in the series. Non-playable characters include Mikka Stone, Sylence, Torque, and Vapor.

The Outer World Investigation Agency (OIA) was something of a successor to the original U.S. Special Forces, as many members of the U.S. Special Forces later join the OIA. The OIA later became the Earthrealm Special Forces.
