The man

Motaro is a member of a race known as Centaurians. Centaurians are native to Outworld, and are the natural enemies of the Shokan. Before Kahn's invasion, Motaro was in charge of organizing the extermination squads that would be used during the invasion. However, when both Goro and Kintaro are defeated, Shao Kahn promotes Motaro to General of Outworld's armies so that he can lead the invasion. The Centaurians living in Outworld see this as a victory over the Shokan and rally to support Kahn in his invasion. Motaro leads Kahn's armies through the portals to the Earth realm. Once there, Motaro commands the armies to begin sweeping the globe and wiping out all the remaining humans. What Motaro doesn't do is to closely guard Shao Kahn himself. He feels confident that if any humans find their way to Kahn's new fortress, that he and Kahn will be more than enough to stop them. His confidence proves to be misguided, and Kahn is driven back into Outworld by mortals. Shao Kahn starts to rebuild his army back in Outworld. Having few strong allies left he allows Motaro to keep his position, until he finds out what he must do to enter this new tournament. Because of the rules of Mortal Kombat, Goro is the only one who can enter the Outworld in the Mortal Kombat between the Earth realm and Netherrealm. To gain Goro's support, Kahn demotes Motaro and gives Goro his former position as General of Outworld's armies. Motaro barely tolerates the demotion, being loyal to Shao Kahn, but he's furious that his position of power has been taken from him, and given to a Shokan
