What if supervillains existed in the Boys?

Superheroes.

The universe they inhabit contain all sorts of dangers and horrors the police, army or even the most badass normal vigilantes can handle.

But in order to support the series' argument that superheroes are not needed, the canon world of the Boys was specifically designed to not need the presence of superheroes.

And so supervillains did not exist in the world of the Boys.

Thus, superheroes had nothing to do but sit on their asses, engage in publicity stunts or take down Supes who don't agree to toe Vought's company line (which there were very few since Vought had a pretty sweet deal to anyone with superpowers).

But what if the Boys' verse had someone like the Skrulls, Brainiac, Thanos or Darkseid?

What if the villains existed? What if the Seven had to do actual superhero work?
