That makes sense. I wanted a more fun version of super strength/durability, with an interesting weakness. In this case, he'd be weakened by being removed from an urban environment. But I can understand if the ability is too hard to keep track of, or too powerful at maximum strength.

Besides, I liked the idea of an ability intended to 'harvest' humanity being used by a good guy. My original idea was that his power, unbeknownst to him, also drained Mana. So he was a non-magic user with stupendous amounts of mana, constantly charging up a veritably limitless reserve to power a spell he didn't know how to cast.

I think I'll keep the general concept, but just change the power to something else.
