Hawkeye

Clint Barton is the Avenging Archer known as Hawkeye! He has occasionally also been known as Goliath and Ronin, but nobody cares. For a while, Bullseye was also known as Hawkeye. Kate Bishop is also known as Hawkeye, but she's not Clint. But he's cool with her using the name, so we are, too.
