Over the last few years, the Mortal Kombat franchise has been leaning more and more into the realm of pop-culture crossovers, right alongside the rest of the gaming industry's leading players. While Mortal Kombat 2011 had just one crossover fighter, that number quickly grew to four in Mortal Kombat X, and five in Mortal Kombat 11, and before Mortal Kombat 1 even hit store shelves, it had already announced that three guest characters would be coming in post-launch DLC, with Invincible's Omni-Man leading the charge.
