Man if you dont have any ideas of where to take the fic, first of all try to focus on the AU Boys timline, for example, 1)Brian can be Homelander and Maeve's son, which will not only make him stronger than canon but also will help to boths reputation. 2) mc expose Vaught and take control but he has way more popularity than canon. Once you finish the boys plot my reomendation is to explore crossover universes ike mortal kombat crossover, there mc can travel MK and even invincible universes.
Man, this story is incredible, especially since there aren't many good fics about The Boys, a word of advice, there's no problem in making the MC a good person, just don't make him naive, like letting people step on him or Vought controlling him, There has to be a balance, like people being afraid of him if they provoke him too much and go into ignorance.
you're stuck because your hero is way too smooth, way too nice, he's not even a normal human being, he's a little twig in the body of the most powerful superhero, it doesn't add up. after a little idea you can move forward with the canon like that it will free you a little or you can talk about the events which led to the creation of the 7 are you already doing some elsewhere. you can show him training with his powers for example in the first episode of the series homelander lets die on a plane you can always see if ask the researchers for research to help him save a plane or something else to do it
dude so far i love this story it's definitely not the scotch talking lol. but seriously it's good. take a break ( even tho I don't want u to) read some books watch some movies get some inspiration if u feel the block. just relax and make the story yours cuz it is make it what u want it to be .good luck and iIlook forward to the next chapter
