I'm not talking about the character writeup. But why the name? I really dislike using established hero names for a product that doesn't relate to the established names. Both DC and Marvel have Nighthawk characters: one is a Western character and the other a Batman clone (strangely enough).
They could have just used Knighthawk and had all the difference the situation demanded. And even had a closer link to Batman, which is what he is supposed to be, anyway.
