Hawkeye

Clint Barton is one of the greatest marksmen alive. He may not have superpowers, but his natural ability to hit virtually any target earned him a place alongside Earth's mightiest heroes. As Hawkeye, he's been known to take down an entire enemy fleet with nothing more than a quiver full of arrows.

For a time, Clint distanced himself from the Avengers, setting off on a quest for vengeance as the assassin called Ronin. He returned to the fold older and wiser, just in time to infiltrate Hydra's Charteris Base and rescue the captured Winter Soldier.
