The series takes place in a world where superheroes embrace the darker side of their massive celebrity and fame, and revolves around a group of titular vigilantes known as "the boys", who set to take down corrupt superheroes with their blue-collar grit and willingness to fight dirty.

The Boys contains examples of the following tropes:
- Eye Beams: A trailer shows Billy Butcher wielding a superpowered baby as a weapon by making it blast blue beams from its eyes at his enemies.
- Off with His Head!: A trailer shows how someone's head is blasted off by the Eye Beams of a superpowered baby held by Billy Butcher. Notably, there's no clean cauterization of the wound as usually expected with beam wounds, and instead there's thick gore from both the neck stump and the separated head.
- Out with a Bang: The trailer shows how an unnamed man giving oral sex to a female superhuman dies when she couldn't control herself during orgasm and accidentally crushes his head with her thighs.
- Strong Flesh, Weak Steel: There's a scene in the trailers where a female superhero jumps in front of the truck that was about to run someone over: she is completely unhurt, while the truck instantly has its engine crumble to pieces.
