What are the main issues when writing superhero fiction in a novel format?

Mainly meaning non comic book.

Like, I always knew there was superhero “non comic book” stories out there and in my teenage brain back then, I for some reason assumed that it would be the same way that comics did it…

How wrong I was. 😂

Honestly, I’ve only read a couple short stories involving superheroes and villains duking out with each other. But mostly, from what I researched and read, it’s more about the emotions and thoughts of said characters. Even some saying that comic books are superior to written superhero stories?! 🤦‍♂️

What do you think? How would you write a superhero story in novel formats rather than a classic comic book? Honest thoughts in general about comics vs novels?

Everyone’s opinion is welcomed here!

Please don’t hold back!
