Did you ever wonder why Johnny Cage had to fight everyone in Mortal Kombat? Even Raiden, the guy supposedly on his side? Well, Johnny wonders that too, and there is no real answer, to be honest.
A recent video may at least provide some insight into how the hell this happened. It's the start of the Mortal Kombat tournament, with Shang Tsung getting senile in his chair, and Goro is left in charge of the roster -- which explains everything, actually.
Poor Goro hates the "R" word, so avoid using that in his presence, lest he break down in tears and then rip your skin from your bones to use as Kleenex.
