Not sure I'd say Shinnok stole Neo's moves when MK came out before Matrix...just saying lol
That's kind of like saying Neo bit off Superman flying around....
But just want to say that fatality is a little different actually as the guy is uppercuting slicing the guys face off, while Scorpion kind of overkills you with shooting a hole through your chest with a fireball first then on your knees slices your face off from top to bottom. So not "exactly" like it.
It is true that some MK characters, fatalities take inspiration from other things(as does everything) though a lot of their fatalities are also very original like KL's, Ermac's and many others.
I have one I'd do for Bo, have him break the guys jaw, open it then throws up in his mouth forcing him to choke and gag while he holes his mouth shut, then as the guy goes on his knees bo takes his bo impales the guys eye socket then twists it full 360 breaking his neck(similar to Jax's) then you see the blood and puke leak out of his face and mouth.
