[The Boys] Question about the last 80 years of this universe’s history (mild spoilers)

Who did the supes fight before the super villains? Just petty criminals all the time? How were they able to keep people engaged in their stories if no one was ever able to challenge them? 

I can’t imagine there is an equivalent to Lex Luthor in this universe since Vought already personifies corporate evil. Similarly, Black Noir can’t have a rogues gallery like Batman considering how quick he is to kill. And if the supes do have weaknesses (like kryptonite), they aren’t widely known or available (assuming the weakness is an item).

I am not sure how the show handles it, but in the comics Villains like Heroes, are just employees of Vought. They even parcitipate often in the same events as heroes, like their yearly party filled with drug use and orgies. Black Noir in particular is noted to have the darkest Villain gallery. But not in the sense that they are more dangerous, but that they have darker public origin stories.
