Hsu Hao is a Mortal Kombat
character that first appeared in Mortal Kombat: Deadly Alliance
. He is a human from Earthrealm and a member of the Red Dragon crime syndicate that takes orders from Mavado
. The device embedded in his chest is an artificial heart.
On orders from the Red Dragons, Hsu Hao worked as a double agent within the Earthrealm's Outworld Investigation Agency. He gained the trust of Jax
and others in order to aid the OIA in the destruction of the Red Dragon's rivals in the Black Dragon clan. Once the Black Dragons were no longer a threat, Mavado instructed Hsu Hao to turn on his supposed allies and destroy their headquarters along with the OIA's portal to the other realms. After rigging the portal to explode using a nuclear device, Hsu Hao leaped through the portal to Outworld
. However, Jax, having discovered Hsu Hao's treachery, manages to follow him before the portal and the OIA headquarters are destroyed.
Following the destruction of OIA headquarters, Hsu Hao receives new orders from Mavado. Quan Chi
has shown interest in allying himself with the Red Dragons, and Mavado agreed to help by eliminating the sorcerer's enemies. Specifically, Mavado gives Hsu Hao the task of eliminating Shang Tsung
, whom Quan Chi suspects will betray him after discovering that Shang allied himself with the oni Moloch
Jax's Deadly Alliance ending follows up on Hsu Hao's ending. In it, he catches up with Hsu Hao while the Red Dragon member is en route to eliminate Shang Tsung. He ambushes the double agent and kills him by tearing out his artificial heart.
Hsu Hao is killed by a shockwave that erupts from Blaze's
violent death and descends into the Netherrealm
. Once there, he becomes a powerful demon of emptiness. He leads an army of oni against Shinnok
and becomes ruler of the Netherrealm.
