Even as hardcore fandom reignites debate over the legitimacy of guest characters in Mortal Kombat X; Creative Director Ed Boon has been discussing some of the franchise crossovers that never quite came to pass.

Speaking with IGN, Boon revealed characters from Terminator and Halloween were among the choices discussed at NetherRealm Studios: "We've tossed around a whole bunch of names, like The Terminator, or something like that. And for various reasons – whether it wasn't a match, or we just couldn't come to terms with it – they didn't happen."
