I honestly think that if these 'heroes' were real, that they'd all be absolutely unrelateable to normal humans. Many of them would have godly abilities (imagine a Wonderwoman or a Blue Marvel) type, and by their very nature would come across as cold and aloof. After all, what would we be to them? At best, farm animals that need to be cared for and tended to. At worst, insects ....fragile in every way.
In Justice you could see how even superheroes would look at Superman and Captain Marvel with a mix of awe and fear. Especially when Cap Marvel would have his broad smile ...absolutely frightening.
And then you'd have the 'human' types - who would even be more arrogant than the powers. Imagine how someone like Bruce Wayne would look at you. He's a billionaire, a mental polymath with IQ scores that are stratospheric in multiple disciplines, he has astounding fighting capability, and he has honed his body to the epitome of human perfection. To the point that even when it comes to healing he's rather do it the old fashioned way than use a mother box.
And there you are eating a hotdog.
Now imagine T'Challa ...like Batman, but now king. Or Reed Richards ...or Tony Stark. Or Von Doom?
Or Ozymandias
All of these guys would be absolute monsters. The powers seeing themselves as literal gods, and the human heroes seeing themselves as our betters since they have made themselves perfect while most of humanity is comprised of slouches.
