It occurs to me that the Heroes will be pretty much depending on Hiro if they're in any kind of straight-up fight; no one has a straightforward offensive power except maybe astral-projection mom (and her abilities are too eratic), and Claire apparenlty doesn't know how to fight (and so can't really take advantage of being unbreakable-girl). The cop at least has some weapons training, but small arms didn't seem to work too well in the first encounter with Sylar.
