At this point it's nothing more than Marvel with curse words and sex scenes and tons of political references. At first the ripoff costumes were part of the parody. They just copied Marvel or DC without really doing any original work. But now that the show is just another capeshit universe the lazily stolen costume designs and powers might as well be plagiarism. They are even copying the Marvel and DC business models.
"Let's take a Marvel superhero, steal their powers and costume design, then have them curse a lot, and engage in deviant sex". This is what being on the creative team for The Boys has essentially become.
