Motaro is one of the most powerful beings in Outworld. Ruler of the Centaurian race of half-man, half-beast creatures (a race known for their hunting prowess), the horned warrior is one of Shao Kahn's most trusted generals and most powerful allies.

Motaro's hatred of humanity is such that he is even willing to ally himself, albeit temporarily, with Sheeva, general of the four-armed Shokan race, the sworn enemies of Motaro's people. Vowing to hunt down every single human soul and spare no one, Motaro leads Extermination Squads on the trail of Sonya Blade and Jax. Eventually, he will confront Jax in a final battle, using his spiked body, beats kicks and flailing tail whip in an effort to destroy the human fighter once and for all.
