Name: True name is unknown. Ermac is what people call him.
Homeworld: Outworld.
Appearance:

Fighting Style: Huaquan (named Hua Chuan in the videogames). Huaquan is an old and ancient technique. Peacefully calm when the fighter is in its stance, the technique is executed like a fast burst of wind when Ermac attacks. Despite that, Ermac's is not that strong when it comes to mere punches and kicks, so the furthermost part of his limbs (like his knuckles or his knees) become lit with his mental powers to enhance his hits.
Special Abilities:
Telekinesis is Ermac's main ability. The hundreds and hundreds of souls that form Ermac have given him various abilities, but the one that he uses masterfully is his telekinesis. He can move every object with it, no matter how big or small it is, no matter if it is a human or an inanimate object. However, he cannot use his powers indefinitely on living creatures, and he has to get rid of them when his control over them is wearing off.
Tele-Ball: Ermac channels his telekinetic abilities into a small and highly dangerous projectile that he shoots out of his hands. The projectile is green and looks unstable given to how much it moves. When it collides with something, it pushes them back in a very violent way.
Tele-Punch: Ermac disappears in the blink of an eye, avoiding any attack and reappears next to his enemy (he can appear in any direction facing his opponent) and punches him with his a devastating blow.
Air denial technique: With his telekinetic powers, Ermac makes the air around the enemy more dense to the point where the air itself hits him slightly, making him lose focus or balance. Not intended to deal good damage or to cause pain, it's just an extremely annoying movement to keep his enemies off the air.
Fatality:
Mind Control: Ermac lifts his enemy of the ground and levitates him pretty high. He then proceeds to clench his fists, crushing the enemy's insides as well as his bones. He then claps his hands together really hard and the enemy turns into a bloody pulp, his body squished and completely destroyed.
Personality: Ermac is a cunning warrior, violent and mercyless but not the kind of talkative person. Although he is highly loyal to Shao Kahn, he doubts about his future and as to wether or not his master will turn on him or not. As thus, he does not trust anyone other than Shao Kahn himself.
Backstory: Ermac was not present during the first Mortal Kombat. In fact, he had not yet been created. Ermac was created from hundreds, almost thousands of souls that Shao Kahn slayed on the various massacres that he did throughout the Outworld. He created Ermac as his own loyal bodyguard, mostly to ensure that no pesky Earthrealm defender would try to play nice. Although Ermac was going to enter the second tournament as a last resource, Shao Kahn wanted to ensure their victory as to accelerate his process of dominating the Earthrealm. He does not have links with anyone other than Shao Kahn or Shang Tsung, given that it was Tsung's elite shadow priests who joined all the souls together into one body. Ermac rejects any living for coming from any other place that is not the Outworld. His presence is nothing but a mere myth to most Earthrealm warriors.
Motivation: Ermac fights only to aid his master in dominating his master's plan. He is nothing more than a pawn and he serves Shao Kahn.
