Let's pretend Hux survives the fall of the First Order and manages to get away. He would lay low for a while - but then what? He needs to make a living, but is far too high profile to just do anything. So he decides to capitalize on his natural ruthlessness and starts his life as a smuggler/space pirate - in disguise.

Then one day, he deals with Leia and the good guys without their knowledge (maybe redeemed Kylo/Ben and/or redeemed Phasma is with them, whether they recognize Hux is up to you). Just imagine the adrenaline rush one would get from such an encounter!

I'm very fine with Gen, if you want to add any ships, I'm partial to Kylo/Hux. No get ships with Hux, though, please, and no background Reylo.
