I would love to see characters getting out of sticky situations because they are genre savvy/know their tropes.
I have a weakness for Hux but I think Poe would be great for this as well - fills with several characters could be awesome in general (the heroes and villains tryiing to out-savvy each other could lead to wonderful chaos). If you want to throw ships into it, I like Kylux, Stormpilot, Finn/Rey and Phasma/Rey but Gen works just fine!
