A mild mannered insurance salesman living in the universe where all action movies takes place gets tired of action heros always crashing everything and wants to make them answer for their latest transgression, without being drawn into the action himself.

Yes, make it personal.

Thanks for the suggestion of a profession. That makes more sense.

I think I'll make it personal for him. Like I mentioned, the inciting incident would be that some kind of big event, like a wedding, that the main character is involved in gets ruined by an action hero and the hero doesn't even stop to apologize, as he's busy chasing/evading some bad guys. So the protagonist focuses on that hero.

>>>a more ironic profession for him

Yes, that makes sense.

Maybe an insurance claims adjuster? He has to sort out who is entitled to how much compensation. And super heroes are super destructive, make his job super hard to do.

However, there is still the issue of need more clarity as to what "answer for their latest transgression" means. How does that translate into a specific objective goal? Also, for plotting purposes, it might be better for him to target a chief offender rather than the whole ensemble of usual suspects; make him an example to warn and restrain others.

fwiw

Good point. I hadn't thought of that. Actually, it's not important for the story that he has that profession.

I'm considering the inciting incident that the protagonist is at some life event, like a wedding. It's interrupted by yet another action hero literally crashing it by taking a high-speed chase through the event. The protagonist gets fed up with the fact that ordinary people's lives are constantly disturbed in such ways.

I'll try to think about a more ironic profession for him to have in this scenario.

What's his motivation? What are the personal stakes for him? He's a *SALESMAN*. More accidents means more demand for coverage, more policies sold, more re-newals -- more premiums he can pocket.

He's working in a salesman's heaven.
