Marvel’s Luke Cage has superhuman strength and bulletproof, unbreakable skin, and that’s way too overpowered to be a “street-level” hero. What makes characters like Spider-Man and Daredevil “fun” is the fact that they are vigilantes who can be hurt; they can be shot or stabbed, and their friends worry about them because they aren’t indestructible. But when you have a character that’s indestructible, then all that danger goes away. Also normal thugs aren’t a threat to you.
I mean yeah I can agree with the gist of it… not really sure they tier them out quite like we have. (Why I think many found it kind of silly to have say, hawkeye and black widow in the original avengers). superheros generally are just set to be a match for… their respective villains.
Obviously the super hero universe thing people have to close their eyes on is the concept of the over the top OP heros nearby are generally equipped well enough that they could usually overcome all the “street level” villains over a lunch break.
To my knowledge that’s kind of it with Luke Cage though is more… he doesn’t have any major mobility or solving advantages. So effectively the way villains need to work around him is… don’t get close.
