So this, from the Civil War Files, made me happy yesterday:
It must be official because, really, what's more official than a guidebook like this, even if it is written from Tony Stark's point of view? She-Hulk is strong as Hercules, strong as Sentry, stronger than Iron Man and stronger than Thing. Sure, it sounds silly, like a "this character can beat up that character" sort of thing, but you know? It's still kind of nifty.
Note: I am conveniently overlooking the fact that the whole ID card could be a mistake, inasmuch as it uses the word "equipment" rather than "powers," and the description of said powers is ambiguous. "Resistance to regeneration?" Ouch.
