What do you think would happen if Scorpion (restored as a living human) and Sub-Zero (now the Lin Kuei's Grandmaster) were randomly teleported to the Kill la Kill universe?
So here's how the plot would begin:
Scorpion and Sub-Zero were fighting their way to Kronika's Keep along with the other Earthrealm and Outworld heroes. Then all of a sudden, a dimensional rift (similar to the one Kronika caused when the past and future MK Timelines merged as they did in MK11) occurs and Scorpion and Sub-Zero are one of many to be sent to different universes. Scorpion and Sub-Zero end up in the Kill la Kill universe just during the events of Episode 11.
I'll let you guys decide what happens next. :)
