Nighthawk is a pretty smart fighter. In a way he’s sort of like a weaker Batman from Marvel. The guy may not be quite as smart as the Dark Knight but he is still a genius in his own right and looked pretty good in Avengers Assemble. He can take out some guns and tech to try and stop Bakugo, but ultimately they will all be futile. Nighthawk just doesn’t have what it takes to defeat an opponent of Bakugo’s caliber. It’s just not happening and he would need a big power up to try and make it close. Bakugo wins.
