There’s Batman, there’s the Guardian, there’s Green Arrow, Hawkeye, and (sort of) Captain America. Also the Falcon and the Manhunter, I believe. In fact I’m sure there’s a lot of them, though only because there are so many superheroes in general. My guess is that the nonpowered heroes tended to crop up in the ’40s and became less commonplace during the Silver Age and after, though the examples above show that they didn’t die out.
This is leaving aside all the Batman satellites. In the interest of franchise homogeneity, anyone who wants to be Batted cannot have special powers. Though, given the number of people who keep getting superpowers, and the number of people who want to be Batman’s crimefighting associate, and the difficulty of Batman’s line of work, you’d think there would be at least some people with superpowers who’d be trying out for the role of girl-Robin or the Silver Bat or whatever. (My thoughts on Kathy Kane, and commenters’ very informative remarks about Bat-training, can be found here.)
I don’t count Iron Man as nonpowered, though he couldn’t have got into the Legion of Superheroes: they think gizmos are cheating. Of course, where you draw the line between Batman’s ton of gimmicks and Tony Stark’s armor could be the subject of much debate. But I’m sure the line’s there someplace.
Don’t forget the Punisher.
I think the dividing line between Iron Man and Batman is whether you wear the technology or whether you simply use the technology.
I think the difference is whether you take the name of the technology (Iron Man) or whether the technology takes the name of you (Batarang.)
Thus, Green Arrow has powers, because he’s named after the arrows. Green Lantern has powers, because he’s named after the ring/lantern thingee. But the Joker doesn’t have powers, because he has Joker Bombs, Joker gas, etc.
Green Arrow has powers? No way.
No, I think Richard has hit on the key principle here.
Oh sure. Take his side.
I’d also say the level of effect that their technology has is a factor.
Batman’s gadgets are pretty neat, but Iron Man’s armour lets him fly around the world at mach-something-or-other, punch through walls, fire lasers and whatnot.
With his armour he can physically go toe-to-toe with the Hulk, while none of Batman’s regular gear puts him on the level of a physical superhuman.
Very good point. The utility belt devices and trick arrows all have strictly limited purposes and effects.
