This character, I obviously made up, is named Kaiser. He is a servant of Shang Tsung. He is very loyal and so, stitched his mouth shut to never talk back to his master. Thats why he wears a cloak which covers his mouth. Kaiser was still a embryo in his mothers womb before he went through his transformation. His mother died while he was still growing inside his mothers womb. He was at the verge of dying until Shang Tsung saved him and raised him to be a great warrior/bodyguard.
