Tarkatan

The Tarkatans are an interracial breed of warriors, a mix of Humans from Outworld and Demons from the Netherrealm.

Biology
They have long pointy teeth, large mouths, and blades protruding from their bodies, especially their arms.

Culture and society
Baraka is their leader, and Mileena is half-Tarkatan as well. The Tarkatans are a nomadic species, mainly populating Outworld's wastelands, but it's discovered that they come from the Netherrealm and migrated to Outworld. This race possesses a love for battle and serves whomever is in command (Shao Kahn, the Deadly Alliance, etc.).
