Ok, I think I’ve found the superhero with the best rogues gallery, in my opinion of course. Spider-Man, and not just because I grew up with him and he was my family’s favorite hero.
I think there’s two big reasons.
- A good power set. Spider-Man is in a sweet spot, strength-wise, where you can pit both low-end nominal humans and strong supervillains against him without it seeming too implausible. This isn’t like (and I know I’m using DC here) Superman where his foes have to be either cosmic or kryptonite-based, or a Daredevil/Batman/Punisher where they have to be weaker.
- The lack of an “evil counterpart” for a while. Evil counterparts are tricky. They have to eventually lose, but they’re symmetric so the fights frequently become less than ideal. The Hulk (Abomination) and Iron Man (A parade of power-suited villains) are notorious for this. It took Spider-Man decades to get a direct evil counterpart in the form of Venom, and even he’s better than most.
This, mixed with silver age creativity, makes Spidey’s villains memorable. Sadly (or maybe not sadly), Marvel has had an aversion to making new villains for a while. I’ve heard part of it is a reluctance by writers to create something they won’t have financial or creative control over, but that doesn’t explain all of it. I think it’s just because the comics themselves are doubling down on being niche, while the movies still have decades of material to mine.
