TheSword
Legend
I’ve listed the themes and style that feature in superhero fiction in a later post.Themes and style? 20th level PCs are dealing with Armies of demons or undead, across time and alternate realities, and fighting literal Gods for the fate of the world!
How does that differ from the Avengers?
If fighting armies of demons or dueling gods was one of the features of superhero fiction then the 80% of superhero fiction that doesn’t feature these things couldn’t be considered such. That patently isn’t the case.
I say again, you are focusing on power as being the thing that defines whether something make it superheroic. Really all power defines is... well... how powerful something is.
