The Centaurians are a race very similar to the Centaur legend which their bodies, agility, behaviors and even their ferocity is based on. Motaro is the only known member of the Centaur race. Long ago, they served the Emperor Shao Kahn as one of his Extermination Squads, and they have been in his favor above their most hated foes, the Shokans, ever since. They even proclaim themselves as the so-called greatest of all the species of Outworld.
Motaro and his people appeared twice in Mortal Kombat: Defenders of the Realm. He and his Centaurian warriors were present at the castle in which Rain held Kitana hostage. They were later seen during the plot to overthrow Shao Kahn. After being warned by Raiden, Motaro appeared to fight the treacherous Shang Tsung and the Shokans led by Sheeva.
