Capcom nixed a Mortal Kombat/Street Fighter crossover because it "wasn’t a good fit"
Mortal Kombat 11 is stuffed with guest characters, with the T800 from Terminator in it right now, and Spawn and the Joker headed to the fighting game soon. IF NetherRealm’s Ed Boon had his way, the game may have had a guest fighter from the venerated Street Fighter series, making heads all over the internet explode.
