Mortal Kombat X: 10 Future Guest Characters That Must Be Included

5. The Joker

Have we already had the Joker in a Mortal Kombat game? Yes. Was it a toned down, weak excuse for an MK game, with the tamest fatalities in it of all time? Oh yes. The Joker even had a fatality that was so brutal in concept, yet very lamely toned down it was reused in the Mortal Kombat game from 2011, simply because it was just too good to not give the full effect. The Joker is one of the most demented villains in comic book history, and his love for destruction and insanity would truly fit perfectly in the destructive environment of Mortal Kombat. Mortal Kombat Vs. DC Universe and Injustice: Gods Among Us both showed off a pretty brutal fighting style, however he hasn't been given the ability to showcase that truly homicidal side since both those games were rated T. For the love of god, in The Dark Knight Returns story, The Joker goes on TV and kills everyone before before ending himself by breaking his own neck (a Hara-Kiri perhaps?). It's safe to say The Joker has the ability to be dark and demented, and what a better place to showcase it than Mortal Kombat, but correctly this time?
