Tarkatans are vicious mutants from the wastes of Outworld, and Baraka is the most brutal among them. Serving in Shao Kahn's army, he gained the Emperor's favor and became one of his personal enforcers. Many of Shao Kahn's opponents have been slain by Baraka's retractable blades, including the defenders of Earthrealm during the Emperor's invasion. But when Shao Kahn was defeated by the Forces of Light, Baraka vowed to avenge his master and returned to Earthrealm to hunt them down.
As the worlds returned to normal, the Kombat Rage dissipated in its victims - except the Tarkatans. Through the Rage, the savage Outworld race has descended to an even greater level of bloodlust. Marking their foreheads with the blood of their enemies, they now storm throughout the realms, dominating all.
