Prince/prince - this would be a medieval setting where the princes are from opposing/warring kingdoms where they somehow fall into a situation requiring them to work together to save both their kingdoms. This line possibly explore themes like slavery/political intrigue etc and require worldbuilding and fleshing of details for two different kingdoms. Please be ready for that if you are interested in this line.
Cop or FBI/Art thief - I would play the art thief. He's someone who has stolen countless famous works. The more famous/difficult it is, the more he views it as a challenge he wants to overcome. But in all his years of doing so, the many people he's divested of enormous sums by way of expensive pieces, he's never really killed anyone or done anything major that would hurt someone. And now his case lands on your doorstep, the famous art thief killed the owner of an art piece after a scuffle and its up to you to try and track down this man that has been giving interpol the runaround for upwards of a decade.
Spaceship captain or hotshot pilot/space pirate or mercenary - I would play the captain/pilot. The captain has helmed his own ship for as long as he can remember, he can be part of a private patrol crew, or anything we want it to be tbh. But he is good at what he does and very young for a captain too. And then he comes across your pirate or mercenary after a scuffle port/planetside on one of their supply stops that throws them both on the same ride-or-die path. We can make up all the rest of the details as we go along.
