Clint Barton, better known as the Avenger Hawkeye, is an expert marksmen that could probably take out a room full of armed soldiers with a nerf gun, but it never hurts to have a good weapon at your side — and Hawkeye's bow is one of the best.
The bow’s recurve design allows him to fire it rapidly without losing too much power. But the best thing about the bow might actually be the quiver, which holds all of his nifty trick arrows. In addition to the standard pointed variety, Hawkeye carries numerous arrows with special attributes, such as an explosive arrow, a taser, and a melter which, as the name implies, is capable of melting through most objects.
He's even used the bow in hand-t0-hand combat on occasion (to varying degrees of success). Luckily, his bow got a bit of an upgrade in Civil War, otherwise, his brief skirmish with Black Panther might not have gone so well.
Hawkeye might be just a guy with a bow and arrow, but his complete mastery of it (coupled with its varying abilities) make it one of the best weapons in the MCU. Who knows, maybe Barton and his bow could be starring in their very own Netflix series in the very near future?
