Both fatalities were impressive in their own right, and happen to be the most graphic depictions shown off to date, so it remains to be seen whether there will be anything else that will top these. For starters, Scorpion will send a fireball flying through Sub-Zero’s chest, where his dangling heart will then be exposed, prior to having the front of his face literally removed from him. This leaves his brain hanging there, and his corpse would then fall onto the ground with a thump.
Quan Chi, on the other hand, relies on some telepathy in order to send Kortal Kahn toward a levitating sword. This would see the sword pierce Kahn through the mouth, and it continues all the way to the handle before being disemboweled, with the coup de grace seeing him cut into two clean halves. Definitely not for the weak hearted.
