Killer Instinct and Mortal Kombat borrowed heavily from each other. Killer Instinct was literally considered a Mortal Kombat clone.
you say "besides having finishing moves" but you need to recognize that it was a HUGE DEAL that both had finishing moves at the time. Finishing moves were crazy and new at the time, and it wasn't mere coincidence that both had them. No Mercies were inspired by fatalities, Brutalities were inspired by ultra combos, stage finishers, copious amounts of blood and gore, etc etc.
And Mortal Kombat is still a huge influence on Killer Instinct today. The first new Killer Instinct character introduced in 2013 was Sadira- who is heavily reminiscent of the Mortal Kombat art style (like, heavily- she looks like a straight-up MK character).
...and if you need further proof the games share the DNA of each other deep inside... the first new character introduced for MKX was ALSO a bug-lady.
I acknowledge the finishing that they borrow from each other 20 years ago. When midways helped published they game. But they are completely different now where I wouldn't even considered it a part of the MK culture.
There are tons of characters in FG that borrow or looks like someone else from other fighting games. Moves, looks, and story.
My point is they are two different identities from one another. I might have thought they were the same when I was playing KI on SNES or Gold on N64, but I can't see that now.
Plus why would't KI want to have their own culture and identity now without relying on getting support from MK culture?
