With the ongoing non-aggression pact being spoke of (even though it's now a memory). Rumour would have it that Reiko will return as top commando for the upcoming Osh-Tekk potentate. While being Kotal Kahn's supreme teacher in the regnant side of things at the same time. This would spark the creation of a new union which no longer involve Earthrealm (maybe Netherrealm and Outworld instead).

That would be cool I guess
