The Master
Episode 17
Writer: James Cappe Director: Harvey Laidman
A mysterious Master comes to Zhu Zin to settle a old score with Shang
Tsung and train new warriors with Kung Lao.

Shang Tsung (series regular Bruce Locke) has escaped to Earth Realm and is
enjoying his freedom when he comes upon Master Cho (guest star George
Kee Cheung)--the very Master Shang Tsung turned against many years ago to
join forces with Shao Kahn. Master Cho has been waiting a very long time to
settle the score with Shang Tsung, and in no time, physically beats him and
then reverses his immortality, turning him into an ancient old man.

The Master leaves Shang Tsung to die and heads to the trading post to find
Kung Loa (series regular Paolo Montalban) and begin training him for future
Mortal Kombat matches. When Taja and Siro (series regulars Kristanna Loken
and Daniel Bernhardt) see this old man wanting to join their ranks, they're both
skeptical and amused--until Master Cho demonstrates some moves that
remove everyone's doubts.

The Master reveals his history with Shang Tsung to Kung Lao. Long ago,
Shang Tsung was a sorcerer being training to defend Earth Realm in Mortal
Kombat. In his first match, Shang Tsung violated the rules of Mortal Kombat
and was basically given the choice to join Shao Kahn's dark force or die (Shao
Kahn sensed the inherent evil in Shang Tsung and exploited it). Among the
moves Shao Kahn taught Shang Tsung was how to take a victim's soul to fuel
one's own immortality. What the Master leaves out of his story is that Shao
Kahn has also touched him with the "curse" of immortality and what it takes
to maintain--the taking of others' life force.

Meanwhile Shang Tsung has summoned Omegis (guest star Angelica
Bridges) to bring her potions and reverse the Master's aging spell. Omegis
comes as beckoned, but only reverses the physical effects, returning Shang
Tsung's youthful looks, but leaving his body on the verge of death. Omegis, it
turns out, was double-crossed years ago by Shang Tsung and sees this as
her opportunity for payback. Many years ago, Omegis had helped Shang
Tsung betray Master Cho, with the understanding that they would partner for
eternity in Outworld. Instead, Omegis was cursed to immortality by Master
Cho and left behind in Earth Realm by Shang Tsung.

Concurrent with Master Cho's arrival, a flu-like epidemic sweeps through Zhu
Zin. The illness is revealed to be the work of Master Cho, who, to stay alive,
must take a bit of life force from the mortals around him--not enough to kill
them, but enough to make them physically ill. When Kung Lao learns of this
(and after Master Cho has tapped Taja), he is repulsed and throws the Master
out of the trading post.

Finally, Omegis agrees to once again help Shang Tsung if he promises to
remove Master Cho's curse and make her mortal again. Shang Tsung agrees,
and Omegis reverses Master Cho's curse. Presently, Master Cho arrives on
the scene and thanks Omegis for falling into his trap of aiding Shang
Tsung--now the two who betrayed him are together and he shall finish them off
once and for all. In the ensuing melee, however, Master Cho is beaten by his
former students, who then seal his not-dead body in a cave to perish.

Her end of the bargain fulfilled, Omegis seeks her mortality from Shang Tsung.
As he did many years earlier, Shang Tsung laughs at Omegis, telling her he
can't reverse the Master's curse and then leaves her. Not one to be fooled
twice, Omegis returns to the cave and unbeknownst to Shang Tsung, frees
Master Cho--now she will have the last laugh.
