This is an issue that's been bugging me for a while now: most superheroes, at least in roleplaying games, are better in EVERY respect than their normal counterparts, even if their powers shouldn't logically affect those areas.
Using _Champions_ as an example, we have Pulsar, who despite being identified as a high-school dropout, is of exactly average intelligence (or maybe above-average--is 8 still the "average" value for a stat?) and Witchcraft, who, even though her training was in mental/spiritual fields, has a DEX of 20, giving her Olympic-level agility. Maybe it's some kind of permanent enchantment.
Why does having energy manipulating powers make you more agile? Why does having the strength to lift a bus make you smarter? Why does being a super-genius make you better-looking?
I can understand a wholly self-made hero like Batman being better all around, but for the most part, even a hero who gets her powers from some freakish accident isn't a normal person with a power set added--if she's an RPG character, she was _already_ smarter, faster, stronger, better-looking, tougher, and more mentally stable than her peers. The fact that she can now fly and shoot firebolts is just gravy.
SPD is a particular sticking point here. Looking at _Champions_ again, EVERYONE has at least 5 SPD. The slowest person here can act two and a half times faster than the average human!
Now that I think about it, this could be explained two ways. First, as stat inflation. I don't know if there is any response to this other than to accept it and redefine what an "average" stat really is. Second, as the "zero-level NPC" viewpoint, in which dramatically unimportant characters are actually assumed to be inferior in all respects to the main characters. Will this lead to increased alienation between the PC's and the rest of the world? Who knows.
I'm either thinking about this too much, or not enough.
