Ok heres a scenario.
Gamefreak makes a short one-off spinoff.
Its a fighting game. Heres a twist: instead of pokemon fighting its mainly the characters from the game. Soem exeptions like mewtwo and other human-like mons work.
The game would act like a typical fighter with a power bar that can be used to summon assist pokemon. Like lets say when its 1/4 full sabrina can summon a kadabra to fling the opponent int othe air, or when its full ghetsis can summon kyruem to use glaciate.

What are some characters that would be in the game?
Heres an example

>ghetsis
>short range attacks with his cane/sword
>long range attacks include shadow triad member to appear,strike, then vanish like lambda 11's wing thingies
>full power meter summons kyream to use glaciate
>1/2 power meter summons hydreigon to use crunch
>1/4 summons drapion to lay toxic spikes
>alternate costumes include original king outfit and cofagrigus colored outfit
