One of Shang Tsung's guards (like the ones in the MK1995 movie) taken in by then bodyguard Reptile or less likely Goro, because of his knowledge on Semitic sorcery and being Israelite. Factors of this craft was not to be known about, only to Shadow Priests. He's sort of a pariah compared to the rest.
It's creativeness but I don't see the need for him or this practice in MK.
Another thing is he could be human Tekunin, which is unheard of in Japan (without going through reasons and details). Don't know if this bandit's allegiance would be to Sektor or Triborg though.
Not a fan of this mask on him but he should have a headdress and maybe a face covering of some sort. They take vermilion seriously, unlike Lin Kuei's who do all different types of colours.
If he was good/neutral he could be a White Lotus member like MK2 Kung Lao, going by the vest. The Shaolin and Gods see the garment bringing good fortune and courage, although that's not the meaning. Imagine if Kung Lao had his own clan/people (a whole different scenario to Kung Jin).
