The developers of Mortal Kombat 1 seem just as excited as we are for the possibility that the new game's Kameo Fighter system might open the door for a bigger array of crossover characters.
Mortal Kombat has often included characters from other franchises - Peacemaker, Homelander, and Omni-Man are all scheduled for the new game's DLC, for example. But MK's brutal fatalities tend to make rights holders squeamish about licensing their characters for appearances in the series. It's tough to imagine, say, Marvel wanting to put Spider-Man in a game where somebody might reach into his neck and rip out his entire spinal cord.
