His power isn't in question. As for Nighthawk, this is the Supreme Power version, who while very tough is by my understanding not in the Batman/Black Panther weight class that the normal Nighthawk occupies.
In the last issue of Captain America and the Mighty Avengers, when faced with the Last Incursion, Monica fires herself at Earth-1610 at the speed of light, fully intending to shatter it before hesitating at the last moment. She, at least, operates under the assumption that she's on a planet-breaking scale of power.
